Mural Survey: Despite Perceived Confidence in Go-To-Market Processes, 85% of Teams Report Regular Misalignment — Putting Outcomes and Revenue at Risk
SAN FRANCISCO--(BUSINESS WIRE)-- Mural, the leading visual collaboration platform, today announced the results of its 2025 Global Go-to-Market (GTM) Alignment Gap Index conducted in collaboration with market research firm The Martec Group. The global survey uncovered that GTM teams made up of sales, marketing, and research and development (R&D) departments are often working toward different goals. It also found that decision makers and individual contributors on those teams disagree on the root cause of misalignment.
GTM teams are increasingly pressured to get products to market faster with less budget and resources. Mural's survey uncovered that 85% of them feel confident about how they collaborate to accomplish that, but the same number frequently find that they are working toward different goals and objectives. That misalignment results in frustrated staff, wasted investment, and revenue forfeited to competitors who get their products to market first.
'Across industries and geographies, we see organizations eager to transform, full of fresh ideas and a drive for change. Yet the true test lies in keeping teams unified throughout the transformation journey, especially during critical go-to-market motions,' said Leigh-Margaret Stull, CEO of Mural. 'As companies accelerate these initiatives and bring new products, AI transformations and processes to market, misalignment can undermine progress. Our latest research reveals where go-to-market efforts hit the most friction and provides useful strategies to help teams align, move forward together, and realize their transformation goals.'
Mural's survey also revealed additional challenges and trends impacting how GTM teams work together:
Collaboration breakdowns negatively impact revenue: 89% of respondents recognized direct revenue-related impacts including reduced customer retention, lower conversion rates, and slower time-to-market. 83% recognized indirect revenue-related impacts including siloed systems and processes, lower morale, increased frustration, and frequent 'fire drills.'
Decision makers are more likely to see poor strategy as a leading cause: Decision makers are twice as likely (43%) to attribute misalignment to a lack of clear strategy and goals compared to individual contributors (22%). Decision makers are also more than twice as likely to attribute it to unclear deadlines and priorities (24% vs 10%).
Sales and marketing teams share learning styles, yet still struggle to communicate: They're equally likely to learn best visually or through reading and writing (61%). However, they are also nearly equally likely to say that it is difficult to communicate clearly between teams (41% for sales, 43% for marketing).
Even with endless software options, GTM teams still collaborate in spreadsheets: Despite massive software investments that should eliminate the need for spreadsheets, 87% of individual contributors use them to collaborate. The same percentage also experience misalignment often either weekly or monthly.
"Our research shows it's not enough to just spend time meeting together,' said Christina Bottis, CMO of Mural. 'Teams must collaborate to reach alignment so they can drive faster GTM outcomes. That alignment requires intentional co-creation, well-defined methods, and the right platforms applied across the GTM team. Mural helps teams achieve this by creating the central source of truth from which decisions get buy-in and made."
Over half of Fortune 100 companies use Mural to plan and execute on their GTM strategies. Sales, marketing, and R&D teams use its AI-powered workspace to increase efficiency, boost productivity, and improve revenue.

IMFINZI® (durvalumab) regimen reduced risk of progression, recurrence or death by 29% in early-stage gastric cancer vs. chemotherapy alone in MATTERHORN Phase III trial
Two-thirds (67.4%) of patients treated with IMFINZI-based perioperative regimen remained event-free at two years First and only immunotherapy to demonstrate statistically significant event-free survival in a global Phase III trial in this setting WILMINGTON, Del., June 01, 2025--(BUSINESS WIRE)--Positive results from the MATTERHORN Phase III trial showed perioperative treatment with AstraZeneca's IMFINZI® (durvalumab) in combination with standard-of-care FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) chemotherapy demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of event-free survival (EFS) versus chemotherapy alone. Patients were treated with neoadjuvant IMFINZI in combination with chemotherapy before surgery, followed by adjuvant IMFINZI in combination with chemotherapy, then IMFINZI monotherapy. The trial evaluated this regimen versus perioperative chemotherapy alone for patients with resectable, early-stage and locally advanced (Stages II, III, IVA) gastric and gastroesophageal junction (GEJ) cancers. These results will be presented today during the Plenary Session at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, IL (abstract #LBA5) and simultaneously published in The New England Journal of Medicine. In a planned interim analysis, patients treated with the IMFINZI-based perioperative regimen showed a 29% reduction in the risk of disease progression, recurrence or death versus chemotherapy alone (based on an EFS hazard ratio [HR] of 0.71; 95% confidence interval [CI] 0.58-0.86; p<0.001). Estimated median EFS was not yet reached for the IMFINZI arm versus 32.8 months for the comparator arm. An estimated 78.2% of patients treated with the IMFINZI-based perioperative regimen were event-free at one year compared to 74.0% in the comparator arm; the estimated 24-month EFS rate was 67.4% versus 58.5%, respectively, signaling a greater magnitude of benefit over time for the IMFINZI-based regimen. For the secondary endpoint of overall survival (OS), a strong trend was observed in favor of the IMFINZI-based perioperative regimen (HR=0.78; 95% CI 0.62-0.97; p=0.025). The trial will continue to follow OS, which will be formally assessed at the final analysis. Yelena Y. Janjigian, MD, Chief Attending Physician of the Gastrointestinal Medical Oncology Service, Memorial Sloan Kettering Cancer Center, New York, and principal investigator for the trial, said: "Despite receiving curative-intent surgery and chemotherapy, patients with gastric and gastroesophageal cancers frequently develop recurrent disease. Results from the MATTERHORN trial showed that more than two-thirds of patients treated with a durvalumab-based perioperative regimen had not experienced a recurrence or were progression-free after two years. This new treatment approach should become the new standard of care in this setting based on these results." Cristian Massacesi, Chief Medical Officer and Oncology Chief Development Officer, AstraZeneca, said: "This immunotherapy-based perioperative regimen has the potential to change the clinical paradigm in early gastric and gastroesophageal junction cancers based on the reduction in risk of progression, recurrence or death by nearly a third and the strong trend towards improved survival. As the third positive trial of perioperative treatment with IMFINZI across multiple tumor types, the MATTERHORN trial further validates this approach and highlights our commitment to bringing novel therapies to early stages of disease where there is the greatest chance for cure." Summary of results: MATTERHORN IMFINZI-based regimen (n=474) Chemotherapy regimen (n=474) EFSi Median EFS (95% CI) (in months) NR (40.7-NR) 32.8 (27.9-NR) HR (95% CI) 0.71 (0.58-0.86) p-valueii p<0.001 EFS rate at 12 months (%) 78.2 74.0 EFS rate at 24 months (%) 67.4 58.5 OS mOS (in months) NR 47.2 HR (95% CI) 0.78 (0.62-0.97) p-valueiii p=0.025 EFS rates are based on Kaplan Meier estimates. Threshold to declare statistical significance p-value<0.0239. Threshold to declare statistical significance p-value<0.0001. The safety profile for IMFINZI and FLOT chemotherapy was consistent with the known profiles of each medicine, and the percentage of patients that completed surgery was similar compared to chemotherapy alone. Grade 3 or higher adverse events due to any cause were similar between the two arms. In a previously reported interim analysis for the key secondary endpoint of pathologic complete response (pCR), the IMFINZI-based regimen more than doubled the pCR rate compared to neoadjuvant chemotherapy alone (19% versus 7%, odds ratio 3.08; p<0.001). IMPORTANT SAFETY INFORMATION There are no contraindications for IMFINZI® (durvalumab) or IMJUDO® (tremelimumab-actl). Severe and Fatal Immune-Mediated Adverse Reactions Important immune-mediated adverse reactions listed under Warnings and Precautions may not include all possible severe and fatal immune-mediated reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. Immune-mediated adverse reactions can occur at any time after starting treatment or after discontinuation. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and before each dose. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue IMFINZI and IMJUDO depending on severity. See USPI Dosing and Administration for specific details. In general, if IMFINZI and IMJUDO requires interruption or discontinuation, administer systemic corticosteroid therapy (1 mg to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy. Immune-Mediated Pneumonitis IMFINZI and IMJUDO can cause immune-mediated pneumonitis, which may be fatal. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation. IMFINZI as a Single Agent In patients who did not receive recent prior radiation, the incidence of immune-mediated pneumonitis was 2.4% (34/1414), including fatal (<0.1%), and Grade 3-4 (0.4%) adverse reactions. In patients who received recent prior radiation, the incidence of pneumonitis (including radiation pneumonitis) in patients with unresectable Stage III NSCLC following definitive chemoradiation within 42 days prior to initiation of IMFINZI in PACIFIC was 18.3% (87/475) in patients receiving IMFINZI and 12.8% (30/234) in patients receiving placebo. Of the patients who received IMFINZI (475), 1.1% were fatal and 2.7% were Grade 3 adverse reactions. The incidence of pneumonitis (including radiation pneumonitis) in patients with LS-SCLC following chemoradiation within 42 days prior to initiation of IMFINZI in ADRIATIC was 14% (37/262) in patients receiving IMFINZI and 6% (16/265) in patients receiving placebo. Of the patients who received IMFINZI (262), 0.4% had a fatal adverse reaction and 2.7% had Grade 3 adverse reactions. The frequency and severity of immune-mediated pneumonitis in patients who did not receive definitive chemoradiation prior to IMFINZI were similar in patients who received IMFINZI as a single agent or with ES-SCLC or BTC when given in combination with chemotherapy. IMFINZI with IMJUDO Immune‑mediated pneumonitis occurred in 1.3% (5/388) of patients receiving IMFINZI and IMJUDO, including fatal (0.3%) and Grade 3 (0.2%) adverse reactions. IMFINZI with IMJUDO and Platinum-Based Chemotherapy Immune-mediated pneumonitis occurred in 3.5% (21/596) of patients receiving IMFINZI in combination with IMJUDO and platinum-based chemotherapy, including fatal (0.5%), and Grade 3 (1%) adverse reactions. Immune-Mediated Colitis IMFINZI with IMJUDO and platinum-based chemotherapy can cause immune-mediated colitis, which may be fatal. IMFINZI and IMJUDO can cause immune-mediated colitis that is frequently associated with diarrhea. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis. In cases of corticosteroid-refractory colitis, consider repeating infectious workup to exclude alternative etiologies. IMFINZI as a Single Agent Immune-mediated colitis occurred in 2% (37/1889) of patients receiving IMFINZI, including Grade 4 (<0.1%) and Grade 3 (0.4%) adverse reactions. IMFINZI with IMJUDO Immune‑mediated colitis or diarrhea occurred in 6% (23/388) of patients receiving IMFINZI and IMJUDO, including Grade 3 (3.6%) adverse reactions. Intestinal perforation has been observed in other studies of IMFINZI and IMJUDO. IMFINZI with IMJUDO and Platinum-Based Chemotherapy Immune-mediated colitis occurred in 6.5% (39/596) of patients receiving IMFINZI in combination with IMJUDO and platinum-based chemotherapy including fatal (0.2%) and Grade 3 (2.5%) adverse reactions. Intestinal perforation and large intestine perforation were reported in 0.1% of patients. Immune-Mediated Hepatitis IMFINZI and IMJUDO can cause immune-mediated hepatitis, which may be fatal.

IMFINZI with IMJUDO Immune-mediated adrenal insufficiency occurred in 1.5% (6/388) of patients receiving IMFINZI and IMJUDO, including Grade 3 (0.3%) adverse reactions. IMFINZI with IMJUDO and Platinum-Based Chemotherapy Immune-mediated adrenal insufficiency occurred in 2.2% (13/596) of patients receiving IMFINZI in combination with IMJUDO and platinum-based chemotherapy, including Grade 3 (0.8%) adverse reactions. Hypophysitis: IMFINZI and IMJUDO can cause immune-mediated hypophysitis. Hypophysitis can present with acute symptoms associated with mass effect such as headache, photophobia, or visual field cuts. Hypophysitis can cause hypopituitarism. Initiate symptomatic treatment including hormone replacement as clinically indicated. IMFINZI as a Single Agent Grade 3 hypophysitis/hypopituitarism occurred in <0.1% (1/1889) of patients who received IMFINZI. IMFINZI with IMJUDO Immune-mediated hypophysitis/hypopituitarism occurred in 1% (4/388) of patients receiving IMFINZI and IMJUDO. IMFINZI with IMJUDO and Platinum-Based Chemotherapy Immune-mediated hypophysitis occurred in 1.3% (8/596) of patients receiving IMFINZI in combination with IMJUDO and platinum-based chemotherapy, including Grade 3 (0.5%) adverse reactions. Thyroid Disorders (Thyroiditis, Hyperthyroidism, and Hypothyroidism): IMFINZI and IMJUDO can cause immune-mediated thyroid disorders. Thyroiditis can present with or without endocrinopathy. Hypothyroidism can follow hyperthyroidism. Initiate hormone replacement therapy for hypothyroidism or institute medical management of hyperthyroidism as clinically indicated. IMFINZI as a Single Agent Immune-mediated thyroiditis occurred in 0.5% (9/1889) of patients receiving IMFINZI, including Grade 3 (<0.1%) adverse reactions.

Exfoliative dermatitis, including Stevens-Johnson Syndrome (SJS), drug rash with eosinophilia and systemic symptoms (DRESS), and toxic epidermal necrolysis (TEN), has occurred with PD-1/L-1 and CTLA-4 blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-exfoliative rashes. IMFINZI as a Single Agent Immune-mediated rash or dermatitis occurred in 1.8% (34/1889) of patients receiving IMFINZI, including Grade 3 (0.4%) adverse reactions. IMFINZI with IMJUDO Immune-mediated rash or dermatitis occurred in 4.9% (19/388) of patients receiving IMFINZI and IMJUDO, including Grade 4 (0.3%) and Grade 3 (1.5%) adverse reactions. IMFINZI with IMJUDO and Platinum-Based Chemotherapy Immune-mediated rash or dermatitis occurred in 7.2% (43/596) of patients receiving IMFINZI in combination with IMJUDO and platinum-based chemotherapy, including Grade 3 (0.3%) adverse reactions. Immune-Mediated Pancreatitis IMFINZI in combination with IMJUDO can cause immune-mediated pancreatitis. Immune-mediated pancreatitis occurred in 2.3% (9/388) of patients receiving IMFINZI and IMJUDO, including Grade 4 (0.3%) and Grade 3 (1.5%) adverse reactions. Other Immune-Mediated Adverse Reactions The following clinically significant, immune-mediated adverse reactions occurred at an incidence of less than 1% each in patients who received IMFINZI and IMJUDO or were reported with the use of other immune-checkpoint inhibitors. Cardiac/vascular: Myocarditis, pericarditis, vasculitis. Nervous system: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy. Ocular: Uveitis, iritis, and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment to include blindness can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss. Gastrointestinal: Pancreatitis including increases in serum amylase and lipase levels, gastritis, duodenitis. Musculoskeletal and connective tissue disorders: Myositis/polymyositis, rhabdomyolysis and associated sequelae including renal failure, arthritis, polymyalgia rheumatic. Endocrine: Hypoparathyroidism. Other (hematologic/immune): Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenia, solid organ transplant rejection, other transplant (including corneal graft) rejection. Infusion-Related Reactions IMFINZI and IMJUDO can cause severe or life-threatening infusion-related reactions. Monitor for signs and symptoms of infusion-related reactions. Interrupt, slow the rate of, or permanently discontinue IMFINZI and IMJUDO based on the severity. See USPI Dosing and Administration for specific details. For Grade 1 or 2 infusion-related reactions, consider using pre-medications with subsequent doses. IMFINZI as a Single Agent Infusion-related reactions occurred in 2.2% (42/1889) of patients receiving IMFINZI, including Grade 3 (0.3%) adverse reactions. IMFINZI with IMJUDO Infusion-related reactions occurred in 2.6% (10/388) of patients receiving IMFINZI and IMJUDO. IMFINZI with IMJUDO and Platinum-Based Chemotherapy Infusion-related reactions occurred in 2.9% (17/596) of patients receiving IMFINZI in combination with IMJUDO and platinum-based chemotherapy, including Grade 3 (0.3%) adverse reactions. Complications of Allogeneic HSCT after IMFINZI Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/L-1 blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/L-1 blockade and allogeneic HSCT. Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/L-1 blocking antibody prior to or after an allogeneic HSCT. Embryo-Fetal Toxicity Based on their mechanism of action and data from animal studies, IMFINZI and IMJUDO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. In females of reproductive potential, verify pregnancy status prior to initiating IMFINZI and IMJUDO and advise them to use effective contraception during treatment with IMFINZI and IMJUDO and for 3 months after the last dose of IMFINZI and IMJUDO. Lactation There is no information regarding the presence of IMFINZI and IMJUDO in human milk; however, because of the potential for serious adverse reactions in breastfed infants from IMFINZI and IMJUDO, advise women not to breastfeed during treatment and for 3 months after the last dose.

Notes Gastric and gastroesophageal junction cancers Gastric (stomach) cancer is the fifth most common cancer worldwide and the fifth-highest leading cause of cancer mortality.1 Nearly one million new patients were diagnosed with gastric cancer in 2022, with approximately 660,000 deaths reported globally.1 In many regions, its incidence has been increasing in patients younger than 50 years old, along with other gastrointestinal (GI) malignancies.2 In 2024, there were approximately 43,000 drug-treated patients in the US, European Union (EU) and Japan with early-stage and locally advanced gastric or GEJ cancer.3 Approximately 62,000 patients in these regions are expected to be newly diagnosed in this setting by 2030.4 GEJ cancer is a type of gastric cancer that arises from and spans the area where the esophagus connects to the stomach.5 Disease recurrence is common in patients with resectable gastric cancer despite undergoing surgery with curative intent and treatment with neoadjuvant/adjuvant chemotherapy. Approximately one in four patients with gastric cancer who undergo surgery develop recurrent disease within one year, and one in four patients do not survive beyond two years, reflecting high unmet medical need.6-7 Additionally, the five-year survival rate remains poor, with less than half of patients alive at five years.8 MATTERHORN MATTERHORN is a randomized, double-blind, placebo-controlled, multi-center, global Phase III trial evaluating IMFINZI as perioperative treatment for patients with resectable Stage II-IVA gastric and GEJ cancers. Perioperative therapy includes treatment before and after surgery, also known as neoadjuvant/adjuvant therapy. In the trial, 948 patients were randomized to receive a 1500mg fixed dose of IMFINZI plus FLOT chemotherapy or placebo plus FLOT chemotherapy every four weeks for two cycles prior to surgery. This was followed by IMFINZI or placebo every four weeks for up to 12 cycles after surgery (including two cycles of IMFINZI or placebo plus FLOT chemotherapy and 10 additional cycles of IMFINZI or placebo monotherapy). In the MATTERHORN trial, the primary endpoint is EFS, defined as time from randomization until the date of one of the following events (whichever occurred first): RECIST (version 1.1, per blinded independent central review assessment) progression that precludes surgery or requires non-protocol therapy during the neoadjuvant period; RECIST progression/recurrence during the adjuvant period; non-RECIST progression that precludes surgery or requires non-protocol therapy during the neoadjuvant period or discovered during surgery; progression/recurrence confirmed by biopsy post-surgery; or death due to any cause. Key secondary endpoints include pCR rate, defined as the proportion of patients who have no detectable cancer cells in resected tumor tissue following neoadjuvant therapy, and OS. The trial enrolled participants in 176 centers in 20 countries, including in the US, Canada, Europe, South America and Asia. IMFINZI IMFINZI® (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumor's immune-evading tactics and releasing the inhibition of immune responses. IMFINZI is also approved in combination with chemotherapy (gemcitabine plus cisplatin) in locally advanced or metastatic biliary tract cancer and in combination with IMJUDO® (tremelimumab-actl) in unresectable hepatocellular carcinoma (HCC). IMFINZI is also approved as a monotherapy in unresectable HCC in Japan and the EU. In addition to its indications in GI cancers, IMFINZI is the global standard of care based on OS in the curative-intent setting of unresectable, Stage III non-small cell lung cancer (NSCLC) in patients whose disease has not progressed after chemoradiotherapy (CRT). Additionally, IMFINZI is approved as a perioperative treatment in combination with neoadjuvant chemotherapy in resectable NSCLC, and in combination with a short course of IMJUDO and chemotherapy for the treatment of metastatic NSCLC. IMFINZI is also approved for limited-stage small cell lung cancer (SCLC) in patients whose disease has not progressed following concurrent platinum-based CRT; and in combination with chemotherapy for the treatment of extensive-stage SCLC. IMFINZI is approved in the US and other countries as a perioperative treatment in combination with neoadjuvant chemotherapy for muscle-invasive bladder cancer based on the NIAGARA Phase III trial. Additionally, IMFINZI plus standard-of-care Bacillus Calmette-Guérin induction and maintenance therapy demonstrated a statistically significant and clinically meaningful improvement in disease-free survival for patients with high-risk non-muscle-invasive bladder cancer in the POTOMAC Phase III trial. IMFINZI in combination with chemotherapy followed by IMFINZI monotherapy is approved as a 1st-line treatment for primary advanced or recurrent endometrial cancer (mismatch repair deficient disease only in US and EU). IMFINZI in combination with chemotherapy followed by olaparib and IMFINZI is approved for patients with mismatch repair proficient advanced or recurrent endometrial cancer in EU and Japan. Since the first approval in May 2017, more than 374,000 patients have been treated with IMFINZI. As part of a broad development program, IMFINZI is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with NSCLC, bladder cancer, breast cancer, ovarian cancer and several gastrointestinal cancers. AstraZeneca in GI cancers AstraZeneca has a broad development program for the treatment of GI cancers across several medicines and a variety of tumor types and stages of disease. In 2022, GI cancers collectively represented approximately 5 million new cancer cases leading to approximately 3.3 million deaths.9 Within this program, the Company is committed to improving outcomes in gastric, liver, biliary tract, esophageal, pancreatic, and colorectal cancers. In addition to its indications in BTC and HCC, IMFINZI is being assessed in combinations, including with IMJUDO, in liver, esophageal and gastric cancers in an extensive development program spanning early to late-stage disease across settings. Fam-trastuzumab deruxtecan-nxki, a HER2-directed antibody drug conjugate, is approved in the US and several other countries for HER2-positive advanced gastric cancer. Fam-trastuzumab deruxtecan-nxki is jointly developed and commercialized by AstraZeneca and Daiichi Sankyo. Olaparib, a first-in-class PARP inhibitor, is approved the US and several other countries for the treatment of BRCA-mutated metastatic pancreatic cancer. Olaparib is developed and commercialized by AstraZeneca and Merck & Co., Inc., known as MSD outside the US and Canada. The Company is also assessing rilvegostomig (AZD2936), a PD-1/TIGIT bispecific antibody, in combination with chemotherapy as an adjuvant therapy in BTC, in combination with bevacizumab with or without IMJUDO as a 1st-line treatment in patients with advanced HCC, and as a 1st-line treatment in patients with HER2-negative, locally advanced unresectable or metastatic gastric and GEJ cancers. Rilvegostomig is also being evaluated in combination with fam-trastuzumab deruxtecan-nxki in previously untreated, HER2-expressing, locally advanced or metastatic BTC. AstraZeneca is advancing multiple modalities that provide complementary mechanisms for targeting Claudin 18.2, a promising therapeutic target in gastric cancer. These include sonesitatug vedotin, a potential first-in-class antibody drug conjugate licensed from KYM Biosciences Inc., currently in Phase III development; AZD5863, a novel Claudin 18.2/CD3 T-cell engager bispecific antibody licensed from Harbour Biomed in Phase I development; and AZD6422, an armored autologous chimeric antigen receptor T-cell (CAR T) therapy, currently being evaluated in an investigator-initiated trial (IIT) in collaboration with AbelZeta in China. In early development, AstraZeneca is developing two Glypican 3 (GPC3) armored CAR Ts in HCC. AZD5851, currently in Phase I development, is being developed globally, and C-CAR031 / AZD7003 is being co-developed with AbelZeta in China where it is under evaluation in an IIT.

IMFINZI ® (durvalumab) regimen reduced risk of progression, recurrence or death by 29% in early-stage gastric cancer vs. chemotherapy alone in MATTERHORN Phase III trial
WILMINGTON, Del.--(BUSINESS WIRE)--Positive results from the MATTERHORN Phase III trial showed perioperative treatment with AstraZeneca's IMFINZI ® (durvalumab) in combination with standard-of-care FLOT (fluorouracil, leucovorin, oxaliplatin, and docetaxel) chemotherapy demonstrated a statistically significant and clinically meaningful improvement in the primary endpoint of event-free survival (EFS) versus chemotherapy alone. Patients were treated with neoadjuvant IMFINZI in combination with chemotherapy before surgery, followed by adjuvant IMFINZI in combination with chemotherapy, then IMFINZI monotherapy. The trial evaluated this regimen versus perioperative chemotherapy alone for patients with resectable, early-stage and locally advanced (Stages II, III, IVA) gastric and gastroesophageal junction (GEJ) cancers. These results will be presented today during the Plenary Session at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting in Chicago, IL (abstract #LBA5) and simultaneously published in The New England Journal of Medicine. In a planned interim analysis, patients treated with the IMFINZI-based perioperative regimen showed a 29% reduction in the risk of disease progression, recurrence or death versus chemotherapy alone (based on an EFS hazard ratio [HR] of 0.71; 95% confidence interval [CI] 0.58-0.86; p<0.001). Estimated median EFS was not yet reached for the IMFINZI arm versus 32.8 months for the comparator arm. An estimated 78.2% of patients treated with the IMFINZI-based perioperative regimen were event-free at one year compared to 74.0% in the comparator arm; the estimated 24-month EFS rate was 67.4% versus 58.5%, respectively, signaling a greater magnitude of benefit over time for the IMFINZI-based regimen. For the secondary endpoint of overall survival (OS), a strong trend was observed in favor of the IMFINZI-based perioperative regimen (HR=0.78; 95% CI 0.62-0.97; p=0.025). The trial will continue to follow OS, which will be formally assessed at the final analysis. Yelena Y. Janjigian, MD, Chief Attending Physician of the Gastrointestinal Medical Oncology Service, Memorial Sloan Kettering Cancer Center, New York, and principal investigator for the trial, said: 'Despite receiving curative-intent surgery and chemotherapy, patients with gastric and gastroesophageal cancers frequently develop recurrent disease. Results from the MATTERHORN trial showed that more than two-thirds of patients treated with a durvalumab-based perioperative regimen had not experienced a recurrence or were progression-free after two years. This new treatment approach should become the new standard of care in this setting based on these results.' Cristian Massacesi, Chief Medical Officer and Oncology Chief Development Officer, AstraZeneca, said: 'This immunotherapy-based perioperative regimen has the potential to change the clinical paradigm in early gastric and gastroesophageal junction cancers based on the reduction in risk of progression, recurrence or death by nearly a third and the strong trend towards improved survival. As the third positive trial of perioperative treatment with IMFINZI across multiple tumor types, the MATTERHORN trial further validates this approach and highlights our commitment to bringing novel therapies to early stages of disease where there is the greatest chance for cure.' The safety profile for IMFINZI and FLOT chemotherapy was consistent with the known profiles of each medicine, and the percentage of patients that completed surgery was similar compared to chemotherapy alone. Grade 3 or higher adverse events due to any cause were similar between the two arms. In a previously reported interim analysis for the key secondary endpoint of pathologic complete response (pCR), the IMFINZI - based regimen more than doubled the pCR rate compared to neoadjuvant chemotherapy alone (19% versus 7%, odds ratio 3.08; p<0.001). IMPORTANT SAFETY INFORMATION There are no contraindications for IMFINZI ® (durvalumab) or IMJUDO ® (tremelimumab-actl). Severe and Fatal Immune-Mediated Adverse Reactions Important immune-mediated adverse reactions listed under Warnings and Precautions may not include all possible severe and fatal immune-mediated reactions. Immune-mediated adverse reactions, which may be severe or fatal, can occur in any organ system or tissue. Immune-mediated adverse reactions can occur at any time after starting treatment or after discontinuation. Monitor patients closely for symptoms and signs that may be clinical manifestations of underlying immune-mediated adverse reactions. Evaluate clinical chemistries including liver enzymes, creatinine, adrenocorticotropic hormone (ACTH) level, and thyroid function at baseline and before each dose. In cases of suspected immune-mediated adverse reactions, initiate appropriate workup to exclude alternative etiologies, including infection. Institute medical management promptly, including specialty consultation as appropriate. Withhold or permanently discontinue IMFINZI and IMJUDO depending on severity. See USPI Dosing and Administration for specific details. In general, if IMFINZI and IMJUDO requires interruption or discontinuation, administer systemic corticosteroid therapy (1 mg to 2 mg/kg/day prednisone or equivalent) until improvement to Grade 1 or less. Upon improvement to Grade 1 or less, initiate corticosteroid taper and continue to taper over at least 1 month. Consider administration of other systemic immunosuppressants in patients whose immune-mediated adverse reactions are not controlled with corticosteroid therapy. Immune-Mediated Pneumonitis IMFINZI and IMJUDO can cause immune-mediated pneumonitis, which may be fatal. The incidence of pneumonitis is higher in patients who have received prior thoracic radiation. IMFINZI as a Single Agent In patients who did not receive recent prior radiation, the incidence of immune-mediated pneumonitis was 2.4% (34/1414), including fatal (<0.1%), and Grade 3-4 (0.4%) adverse reactions. In patients who received recent prior radiation, the incidence of pneumonitis (including radiation pneumonitis) in patients with unresectable Stage III NSCLC following definitive chemoradiation within 42 days prior to initiation of IMFINZI in PACIFIC was 18.3% (87/475) in patients receiving IMFINZI and 12.8% (30/234) in patients receiving placebo. Of the patients who received IMFINZI (475), 1.1% were fatal and 2.7% were Grade 3 adverse reactions. The incidence of pneumonitis (including radiation pneumonitis) in patients with LS-SCLC following chemoradiation within 42 days prior to initiation of IMFINZI in ADRIATIC was 14% (37/262) in patients receiving IMFINZI and 6% (16/265) in patients receiving placebo. Of the patients who received IMFINZI (262), 0.4% had a fatal adverse reaction and 2.7% had Grade 3 adverse reactions. The frequency and severity of immune-mediated pneumonitis in patients who did not receive definitive chemoradiation prior to IMFINZI were similar in patients who received IMFINZI as a single agent or with ES-SCLC or BTC when given in combination with chemotherapy. IMFINZI with IMJUDO Immune‑mediated pneumonitis occurred in 1.3% (5/388) of patients receiving IMFINZI and IMJUDO, including fatal (0.3%) and Grade 3 (0.2%) adverse reactions. IMFINZI with IMJUDO and Platinum-Based Chemotherapy Immune-mediated pneumonitis occurred in 3.5% (21/596) of patients receiving IMFINZI in combination with IMJUDO and platinum-based chemotherapy, including fatal (0.5%), and Grade 3 (1%) adverse reactions. Immune-Mediated Colitis IMFINZI with IMJUDO and platinum-based chemotherapy can cause immune-mediated colitis, which may be fatal. IMFINZI and IMJUDO can cause immune-mediated colitis that is frequently associated with diarrhea. Cytomegalovirus (CMV) infection/reactivation has been reported in patients with corticosteroid-refractory immune-mediated colitis.

Immune-Mediated Dermatology Reactions IMFINZI and IMJUDO can cause immune-mediated rash or dermatitis. Exfoliative dermatitis, including Stevens-Johnson Syndrome (SJS), drug rash with eosinophilia and systemic symptoms (DRESS), and toxic epidermal necrolysis (TEN), has occurred with PD-1/L-1 and CTLA-4 blocking antibodies. Topical emollients and/or topical corticosteroids may be adequate to treat mild to moderate non-exfoliative rashes. IMFINZI as a Single Agent Immune-mediated rash or dermatitis occurred in 1.8% (34/1889) of patients receiving IMFINZI, including Grade 3 (0.4%) adverse reactions. IMFINZI with IMJUDO Immune-mediated rash or dermatitis occurred in 4.9% (19/388) of patients receiving IMFINZI and IMJUDO, including Grade 4 (0.3%) and Grade 3 (1.5%) adverse reactions. IMFINZI with IMJUDO and Platinum-Based Chemotherapy Immune-mediated rash or dermatitis occurred in 7.2% (43/596) of patients receiving IMFINZI in combination with IMJUDO and platinum-based chemotherapy, including Grade 3 (0.3%) adverse reactions. Immune-Mediated Pancreatitis IMFINZI in combination with IMJUDO can cause immune-mediated pancreatitis. Immune-mediated pancreatitis occurred in 2.3% (9/388) of patients receiving IMFINZI and IMJUDO, including Grade 4 (0.3%) and Grade 3 (1.5%) adverse reactions. Other Immune-Mediated Adverse Reactions The following clinically significant, immune-mediated adverse reactions occurred at an incidence of less than 1% each in patients who received IMFINZI and IMJUDO or were reported with the use of other immune-checkpoint inhibitors. Cardiac/vascular: Myocarditis, pericarditis, vasculitis. Nervous system: Meningitis, encephalitis, myelitis and demyelination, myasthenic syndrome/myasthenia gravis (including exacerbation), Guillain-Barré syndrome, nerve paresis, autoimmune neuropathy. Ocular: Uveitis, iritis, and other ocular inflammatory toxicities can occur. Some cases can be associated with retinal detachment. Various grades of visual impairment to include blindness can occur. If uveitis occurs in combination with other immune-mediated adverse reactions, consider a Vogt-Koyanagi-Harada-like syndrome, as this may require treatment with systemic steroids to reduce the risk of permanent vision loss. Gastrointestinal: Pancreatitis including increases in serum amylase and lipase levels, gastritis, duodenitis. Musculoskeletal and connective tissue disorders: Myositis/polymyositis, rhabdomyolysis and associated sequelae including renal failure, arthritis, polymyalgia rheumatic. Endocrine: Hypoparathyroidism. Other (hematologic/immune): Hemolytic anemia, aplastic anemia, hemophagocytic lymphohistiocytosis, systemic inflammatory response syndrome, histiocytic necrotizing lymphadenitis (Kikuchi lymphadenitis), sarcoidosis, immune thrombocytopenia, solid organ transplant rejection, other transplant (including corneal graft) rejection. Infusion-Related Reactions IMFINZI and IMJUDO can cause severe or life-threatening infusion-related reactions. Monitor for signs and symptoms of infusion-related reactions. Interrupt, slow the rate of, or permanently discontinue IMFINZI and IMJUDO based on the severity. See USPI Dosing and Administration for specific details. For Grade 1 or 2 infusion-related reactions, consider using pre-medications with subsequent doses. IMFINZI as a Single Agent Infusion-related reactions occurred in 2.2% (42/1889) of patients receiving IMFINZI, including Grade 3 (0.3%) adverse reactions. IMFINZI with IMJUDO Infusion-related reactions occurred in 2.6% (10/388) of patients receiving IMFINZI and IMJUDO. IMFINZI with IMJUDO and Platinum-Based Chemotherapy Infusion-related reactions occurred in 2.9% (17/596) of patients receiving IMFINZI in combination with IMJUDO and platinum-based chemotherapy, including Grade 3 (0.3%) adverse reactions. Complications of Allogeneic HSCT after IMFINZI Fatal and other serious complications can occur in patients who receive allogeneic hematopoietic stem cell transplantation (HSCT) before or after being treated with a PD-1/L-1 blocking antibody. Transplant-related complications include hyperacute graft-versus-host disease (GVHD), acute GVHD, chronic GVHD, hepatic veno-occlusive disease (VOD) after reduced intensity conditioning, and steroid-requiring febrile syndrome (without an identified infectious cause). These complications may occur despite intervening therapy between PD-1/L-1 blockade and allogeneic HSCT. Follow patients closely for evidence of transplant-related complications and intervene promptly. Consider the benefit versus risks of treatment with a PD-1/L-1 blocking antibody prior to or after an allogeneic HSCT. Embryo-Fetal Toxicity Based on their mechanism of action and data from animal studies, IMFINZI and IMJUDO can cause fetal harm when administered to a pregnant woman. Advise pregnant women of the potential risk to a fetus. In females of reproductive potential, verify pregnancy status prior to initiating IMFINZI and IMJUDO and advise them to use effective contraception during treatment with IMFINZI and IMJUDO and for 3 months after the last dose of IMFINZI and IMJUDO. Lactation There is no information regarding the presence of IMFINZI and IMJUDO in human milk; however, because of the potential for serious adverse reactions in breastfed infants from IMFINZI and IMJUDO, advise women not to breastfeed during treatment and for 3 months after the last dose.

You may report side effects related to AstraZeneca products. Notes Gastric and gastroesophageal junction cancers Gastric (stomach) cancer is the fifth most common cancer worldwide and the fifth-highest leading cause of cancer mortality. 1 Nearly one million new patients were diagnosed with gastric cancer in 2022, with approximately 660,000 deaths reported globally. 1 In many regions, its incidence has been increasing in patients younger than 50 years old, along with other gastrointestinal (GI) malignancies. 2 In 2024, there were approximately 43,000 drug-treated patients in the US, European Union (EU) and Japan with early-stage and locally advanced gastric or GEJ cancer. 3 Approximately 62,000 patients in these regions are expected to be newly diagnosed in this setting by 2030. 4 GEJ cancer is a type of gastric cancer that arises from and spans the area where the esophagus connects to the stomach. 5 Disease recurrence is common in patients with resectable gastric cancer despite undergoing surgery with curative intent and treatment with neoadjuvant/adjuvant chemotherapy. Approximately one in four patients with gastric cancer who undergo surgery develop recurrent disease within one year, and one in four patients do not survive beyond two years, reflecting high unmet medical need. 6-7 Additionally, the five-year survival rate remains poor, with less than half of patients alive at five years. 8 MATTERHORN MATTERHORN is a randomized, double-blind, placebo-controlled, multi-center, global Phase III trial evaluating IMFINZI as perioperative treatment for patients with resectable Stage II-IVA gastric and GEJ cancers. Perioperative therapy includes treatment before and after surgery, also known as neoadjuvant/adjuvant therapy. In the trial, 948 patients were randomized to receive a 1500mg fixed dose of IMFINZI plus FLOT chemotherapy or placebo plus FLOT chemotherapy every four weeks for two cycles prior to surgery. This was followed by IMFINZI or placebo every four weeks for up to 12 cycles after surgery (including two cycles of IMFINZI or placebo plus FLOT chemotherapy and 10 additional cycles of IMFINZI or placebo monotherapy). In the MATTERHORN trial, the primary endpoint is EFS, defined as time from randomization until the date of one of the following events (whichever occurred first): RECIST (version 1.1, per blinded independent central review assessment) progression that precludes surgery or requires non-protocol therapy during the neoadjuvant period; RECIST progression/recurrence during the adjuvant period; non-RECIST progression that precludes surgery or requires non-protocol therapy during the neoadjuvant period or discovered during surgery; progression/recurrence confirmed by biopsy post-surgery; or death due to any cause. Key secondary endpoints include pCR rate, defined as the proportion of patients who have no detectable cancer cells in resected tumor tissue following neoadjuvant therapy, and OS. The trial enrolled participants in 176 centers in 20 countries, including in the US, Canada, Europe, South America and Asia. IMFINZI IMFINZI ® (durvalumab) is a human monoclonal antibody that binds to the PD-L1 protein and blocks the interaction of PD-L1 with the PD-1 and CD80 proteins, countering the tumor's immune-evading tactics and releasing the inhibition of immune responses. IMFINZI is also approved in combination with chemotherapy (gemcitabine plus cisplatin) in locally advanced or metastatic biliary tract cancer and in combination with IMJUDO ® (tremelimumab-actl) in unresectable hepatocellular carcinoma (HCC). IMFINZI is also approved as a monotherapy in unresectable HCC in Japan and the EU. In addition to its indications in GI cancers, IMFINZI is the global standard of care based on OS in the curative-intent setting of unresectable, Stage III non-small cell lung cancer (NSCLC) in patients whose disease has not progressed after chemoradiotherapy (CRT). Additionally, IMFINZI is approved as a perioperative treatment in combination with neoadjuvant chemotherapy in resectable NSCLC, and in combination with a short course of IMJUDO and chemotherapy for the treatment of metastatic NSCLC. IMFINZI is also approved for limited-stage small cell lung cancer (SCLC) in patients whose disease has not progressed following concurrent platinum-based CRT; and in combination with chemotherapy for the treatment of extensive-stage SCLC. IMFINZI is approved in the US and other countries as a perioperative treatment in combination with neoadjuvant chemotherapy for muscle-invasive bladder cancer based on the NIAGARA Phase III trial. Additionally, IMFINZI plus standard-of-care Bacillus Calmette-Guérin induction and maintenance therapy demonstrated a statistically significant and clinically meaningful improvement in disease-free survival for patients with high-risk non-muscle-invasive bladder cancer in the POTOMAC Phase III trial. IMFINZI in combination with chemotherapy followed by IMFINZI monotherapy is approved as a 1st-line treatment for primary advanced or recurrent endometrial cancer (mismatch repair deficient disease only in US and EU). IMFINZI in combination with chemotherapy followed by olaparib and IMFINZI is approved for patients with mismatch repair proficient advanced or recurrent endometrial cancer in EU and Japan. Since the first approval in May 2017, more than 374,000 patients have been treated with IMFINZI. As part of a broad development program, IMFINZI is being tested as a single treatment and in combinations with other anti-cancer treatments for patients with NSCLC, bladder cancer, breast cancer, ovarian cancer and several gastrointestinal cancers. AstraZeneca in GI cancers AstraZeneca has a broad development program for the treatment of GI cancers across several medicines and a variety of tumor types and stages of disease. In 2022, GI cancers collectively represented approximately 5 million new cancer cases leading to approximately 3.3 million deaths. 9 Within this program, the Company is committed to improving outcomes in gastric, liver, biliary tract, esophageal, pancreatic, and colorectal cancers. In addition to its indications in BTC and HCC, IMFINZI is being assessed in combinations, including with IMJUDO, in liver, esophageal and gastric cancers in an extensive development program spanning early to late-stage disease across settings. Fam-trastuzumab deruxtecan-nxki, a HER2-directed antibody drug conjugate, is approved in the US and several other countries for HER2-positive advanced gastric cancer. Fam-trastuzumab deruxtecan-nxki is jointly developed and commercialized by AstraZeneca and Daiichi Sankyo. Olaparib, a first-in-class PARP inhibitor, is approved the US and several other countries for the treatment of BRCA- mutated metastatic pancreatic cancer. Olaparib is developed and commercialized by AstraZeneca and Merck & Co., Inc., known as MSD outside the US and Canada. The Company is also assessing rilvegostomig (AZD2936), a PD-1/TIGIT bispecific antibody, in combination with chemotherapy as an adjuvant therapy in BTC, in combination with bevacizumab with or without IMJUDO as a 1st-line treatment in patients with advanced HCC, and as a 1st-line treatment in patients with HER2-negative, locally advanced unresectable or metastatic gastric and GEJ cancers. Rilvegostomig is also being evaluated in combination with fam-trastuzumab deruxtecan-nxki in previously untreated, HER2-expressing, locally advanced or metastatic BTC. AstraZeneca is advancing multiple modalities that provide complementary mechanisms for targeting Claudin 18.2, a promising therapeutic target in gastric cancer. These include sonesitatug vedotin, a potential first-in-class antibody drug conjugate licensed from KYM Biosciences Inc., currently in Phase III development; AZD5863, a novel Claudin 18.2/CD3 T-cell engager bispecific antibody licensed from Harbour Biomed in Phase I development; and AZD6422, an armored autologous chimeric antigen receptor T-cell (CAR T) therapy, currently being evaluated in an investigator-initiated trial (IIT) in collaboration with AbelZeta in China.

Kite Presents New Real-World Data Supporting Use of Potentially Curative Yescarta ® in Outpatient Care Setting for Patients with Relapsed/Refractory Large B-Cell Lymphoma at ASCO 2025
SANTA MONICA, Calif.--(BUSINESS WIRE)--Kite, a Gilead Company (Nasdaq: GILD), today announced real-world data evaluating the safety and effectiveness of Yescarta ® (axicabtagene ciloleucel) for patients with relapsed/refractory large B-cell lymphoma (R/R LBCL) assigned to treatment in an outpatient setting (no planned hospital stay) versus those assigned to an inpatient setting in a hospital. The analysis, based on data collected from the Center for International Blood and Marrow Transplant Research (CIBMTR) registry, observed that safety and effectiveness outcomes for people treated as outpatients were comparable to those patients who received treatment in a hospital. The results were shared in a presentation (Abstract #7023) during the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting. 'The encouraging results from this study corroborate reports from treatment centers and prior studies in the real world that illustrate the potential feasibility of administering axi-cel in the outpatient setting for people with relapsed or refractory large B-cell lymphoma,' said Dr. Fateeha Furqan, lead investigator, The University of Texas MD Anderson Cancer Center. 'Outpatient administration of axi-cel has cost-effective advantages over inpatient treatment, including less burden on hospitals. These clinical results reflect the fact that the knowledge and experience needed to safely administer the therapy has only grown since axi-cel was first approved in 2017.' Data were collected from the CIBMTR observational database (between July 2021 to Nov 2023). The final analysis assessed data on patients with R/R LBCL from 75 treatment centers, comparing 119 individuals who were assigned to receive Yescarta in the outpatient setting to 119 patients assigned to receive Yescarta in the inpatient setting. With a median follow-up of 12 months, no general differences were found between the 2 groups in the rates of cytokine release syndrome, neurologic events or immune effector cell-associated neurotoxicity syndrome grade ≥ 3. Almost one-fourth of 119 patients who were assigned to receive Yescarta in the outpatient setting did not require hospital admission within 30 days, and half of 119 patients did not require hospital admission within 3 days based on propensity score-matched dataset. These real-world data are not currently in the U.S. Prescribing Information. "We are seeing a growing body of evidence that suggests outpatient administration of Yescarta could be reliable and safe in suitable settings, with benefits for the patient, their family and healthcare system,' said Dominique Tonelli, M.D., Vice President and Global Head of Medical Affairs, Kite. 'We are confident that these promising results will help inform providers to expand the number of patients who can achieve the curative potential of a one-time treatment with Yescarta.' Patients assigned to the outpatient and inpatient treatment groups were matched by age, sex, comorbidities, lactate dehydrogenase (LDH), bulky disease, prior lines of therapy, chemosensitivity and infusion year. Patients assigned to the outpatient group had a median age of 63 years (25% ≥ 70), 66% were male and 67% had ≥ 1 comorbidity. Half had elevated LDH and 73% had 1 prior line of therapy. Bulky disease was reported in 3% and 60% had chemo-resistant disease. About LBCL Globally, LBCL is the most common type of non-Hodgkin lymphoma. In the United States, more than 18,000 people are diagnosed with LBCL each year. About 30-40% of patients with LBCL will need second-line treatment, as their cancer will either relapse (return) or become refractory (not respond) to initial treatment. About Yescarta Please see full Prescribing Information, including BOXED WARNING below and Medication Guide. YESCARTA is a CD19-directed genetically modified autologous T cell immunotherapy indicated for the treatment of: Adult patients with large B-cell lymphoma that is refractory to first-line chemoimmunotherapy or that relapses within 12 months of first-line chemoimmunotherapy. Adult patients with relapsed or refractory large B-cell lymphoma after two or more lines of systemic therapy, including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, primary mediastinal large B-cell lymphoma, high grade B-cell lymphoma, and DLBCL arising from follicular lymphoma. Limitations of Use: YESCARTA is not indicated for the treatment of patients with primary central nervous system lymphoma. Adult patients with relapsed or refractory follicular lymphoma (FL) after two or more lines of systemic therapy. This indication is approved under accelerated approval based on response rate. Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s). U.S. IMPORTANT SAFETY INFORMATION BOXED WARNING: CYTOKINE RELEASE SYNDROME, NEUROLOGIC TOXICITIES and SECONDARY HEMATOLOGICAL MALIGNANCIES Cytokine Release Syndrome (CRS), including fatal or life-threatening reactions, occurred in patients receiving YESCARTA. Do not administer YESCARTA to patients with active infection or inflammatory disorders. Treat severe or life-threatening CRS with tocilizumab or tocilizumab and corticosteroids. Neurologic toxicities, including fatal or life-threatening reactions, occurred in patients receiving YESCARTA, including concurrently with CRS or after CRS resolution. Monitor for neurologic toxicities after treatment with YESCARTA. Provide supportive care and/or corticosteroids, as needed. T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies, including YESCARTA. YESCARTA is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the YESCARTA and TECARTUS REMS Program. CYTOKINE RELEASE SYNDROME (CRS) CRS, including fatal or life-threatening reactions, occurred following treatment with YESCARTA. CRS occurred in 90% (379/422) of patients with non-Hodgkin lymphoma (NHL) receiving YESCARTA, including ≥ Grade 3 (Lee grading system1) CRS in 9%. CRS occurred in 93% (256/276) of patients with large B-cell lymphoma (LBCL), including ≥ Grade 3 CRS in 9%. Among patients with LBCL who died after receiving YESCARTA, four had ongoing CRS events at the time of death. For patients with LBCL in ZUMA-1, the median time to onset of CRS was 2 days following infusion (range: 1 to 12 days) and the median duration of CRS was 7 days (range: 2 to 58 days). For patients with LBCL in ZUMA-7, the median time to onset of CRS was 3 days following infusion (range: 1 to 10 days) and the median duration was 7 days (range: 2 to 43 days). CRS occurred in 84% (123/146) of patients with indolent non-Hodgkin lymphoma (iNHL) in ZUMA-5, including ≥ Grade 3 CRS in 8%. Among patients with iNHL who died after receiving YESCARTA, one patient had an ongoing CRS event at the time of death. The median time to onset of CRS was 4 days (range: 1 to 20 days) and the median duration was 6 days (range: 1 to 27 days) for patients with iNHL. Key manifestations of CRS (≥ 10%) in all patients combined included fever (85%), hypotension (40%), tachycardia (32%), chills (22%), hypoxia (20%), headache (15%), and fatigue (12%). Serious events that may be associated with CRS include, cardiac arrhythmias (including atrial fibrillation and ventricular tachycardia), renal insufficiency, cardiac failure, respiratory failure, cardiac arrest, capillary leak syndrome, multi-organ failure, and hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS). The impact of tocilizumab and/or corticosteroids on the incidence and severity of CRS was assessed in two subsequent cohorts of LBCL patients in ZUMA-1. Among patients who received tocilizumab and/or corticosteroids for ongoing Grade 1 events. CRS occurred in 93% (38/41), including 2% (1/41) with Grade 3 CRS; no patients experienced a Grade 4 or 5 event. The median time to onset of CRS was 2 days (range: 1 to 8 days) and the median duration of CRS was 7 days (range: 2 to 16 days). Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of YESCARTA. Thirty-one of the 39 patients (79%) developed CRS at which point the patients were managed with tocilizumab and/or therapeutic doses of corticosteroids with no patients developing Grade 3 or higher CRS. The median time to onset of CRS was 5 days (range: 1 to 15 days) and the median duration of CRS was 4 days (range: 1 to 10 days). Although there is no known mechanistic explanation, consider the risk and benefits of prophylactic corticosteroids in the context of pre-existing comorbidities for the individual patient and the potential for the risk of Grade 4 and prolonged neurologic toxicities. Ensure that 2 doses of tocilizumab are available prior to infusion of YESCARTA. Monitor patients at least daily for 7 days at the certified healthcare facility following infusion for signs and symptoms of CRS. Monitor patients for signs or symptoms of CRS for 4 weeks after infusion. Counsel patients to seek immediate medical attention should signs or symptoms of CRS occur at any time. At the first sign of CRS, institute treatment with supportive care, tocilizumab, or tocilizumab and corticosteroids as indicated. NEUROLOGIC TOXICITIES Neurologic toxicities (including immune effector cell-associated neurotoxicity syndrome) that were fatal or life- threatening occurred. Neurologic toxicities occurred in 78% (330/422) of all patients with NHL receiving YESCARTA, including ≥ Grade 3 in 25%. Neurologic toxicities occurred in 87% (94/108) of patients with LBCL in ZUMA-1, including ≥ Grade 3 in 31% and in 74% (124/168) of patients in ZUMA-7 including ≥ Grade 3 in 25%. The median time to onset was 4 days (range: 1-43 days) and the median duration was 17 days for patients with LBCL in ZUMA-1. The median time to onset for neurologic toxicity was 5 days (range:1- 133 days) and median duration was 15 days in patients with LBCL in ZUMA-7. Neurologic toxicities occurred in 77% (112/146) of patients with iNHL, including ≥ Grade 3 in 21%. The median time to onset was 6 days (range: 1-79 days) and the median duration was 16 days. Ninety-eight percent of all neurologic toxicities in patients with LBCL and 99% of all neurologic toxicities in patients with iNHL occurred within the first 8 weeks of YESCARTA infusion. Neurologic toxicities occurred within the first 7 days of infusion for 87% of affected patients with LBCL and 74% of affected patients with iNHL. The most common neurologic toxicities (≥ 10%) in all patients combined included encephalopathy (50%), headache (43%), tremor (29%), dizziness (21%), aphasia (17%), delirium (15%), and insomnia (10%). Prolonged encephalopathy lasting up to 173 days was noted. Serious events, including aphasia, leukoencephalopathy, dysarthria, lethargy, and seizures occurred. Fatal and serious cases of cerebral edema and encephalopathy, including late-onset encephalopathy, have occurred. The impact of tocilizumab and/or corticosteroids on the incidence and severity of neurologic toxicities was assessed in 2 subsequent cohorts of LBCL patients in ZUMA-1. Among patients who received corticosteroids at the onset of Grade 1 toxicities, neurologic toxicities occurred in 78% (32/41) and 20% (8/41) had Grade 3 neurologic toxicities; no patients experienced a Grade 4 or 5 event. The median time to onset of neurologic toxicities was 6 days (range: 1-93 days) with a median duration of 8 days (range: 1-144 days). Prophylactic treatment with corticosteroids was administered to a cohort of 39 patients for 3 days beginning on the day of infusion of YESCARTA. Of those patients, 85% (33/39) developed neurologic toxicities, 8% (3/39) developed Grade 3, and 5% (2/39) developed Grade 4 neurologic toxicities. The median time to onset of neurologic toxicities was 6 days (range: 1-274 days) with a median duration of 12 days (range: 1-107 days). Prophylactic corticosteroids for management of CRS and neurologic toxicities may result in higher grade of neurologic toxicities or prolongation of neurologic toxicities, delay the onset and decrease the duration of CRS. Monitor patients for signs and symptoms of neurologic toxicities at least daily for 7 days at the certified healthcare facility, and for 4 weeks thereafter, and treat promptly. REMS Because of the risk of CRS and neurologic toxicities, YESCARTA is available only through a restricted program called the YESCARTA and TECARTUS REMS Program which requires that: Healthcare facilities that dispense and administer YESCARTA must be enrolled and comply with the REMS requirements and must have on-site, immediate access to a minimum of 2 doses of tocilizumab for each patient for infusion within 2 hours after YESCARTA infusion, if needed for treatment of CRS. Certified healthcare facilities must ensure that healthcare providers who prescribe, dispense, or administer YESCARTA are trained about the management of CRS and neurologic toxicities. Further information is available at or 1-844-454-KITE (5483). HYPERSENSITIVITY REACTIONS Allergic reactions, including serious hypersensitivity reactions or anaphylaxis, may occur with the infusion of YESCARTA. SERIOUS INFECTIONS Severe or life-threatening infections occurred. Infections (all grades) occurred in 45% of patients with NHL. Grade 3 or higher infections occurred in 17% of patients, including ≥ Grade 3 or higher infections with an unspecified pathogen in 12%, bacterial infections in 5%, viral infections in 3%, and fungal infections in 1%. YESCARTA should not be administered to patients with clinically significant active systemic infections. Monitor patients for signs and symptoms of infection before and after infusion and treat appropriately. Administer prophylactic antimicrobials according to local guidelines. Febrile neutropenia was observed in 36% of all patients with NHL and may be concurrent with CRS. In the event of febrile neutropenia, evaluate for infection and manage with broad-spectrum antibiotics, fluids, and other supportive care as medically indicated. In immunosuppressed patients, including those who have received YESCARTA, life-threatening and fatal opportunistic infections including disseminated fungal infections (e.g., candida sepsis and aspergillus infections) and viral reactivation (e.g., human herpes virus-6 [HHV-6] encephalitis and JC virus progressive multifocal leukoencephalopathy [PML]) have been reported. The possibility of HHV-6 encephalitis and PML should be considered in immunosuppressed patients with neurologic events and appropriate diagnostic evaluations should be performed. Hepatitis B virus (HBV) reactivation, in some cases resulting in fulminant hepatitis, hepatic failure, and death, can occur in patients treated with drugs directed against B cells, including YESCARTA. Perform screening for HBV, HCV, and HIV in accordance with clinical guidelines before collection of cells for manufacturing. PROLONGED CYTOPENIAS Patients may exhibit cytopenias for several weeks following lymphodepleting chemotherapy and YESCARTA infusion. ≥ Grade 3 cytopenias not resolved by Day 30 following YESCARTA infusion occurred in 39% of all patients with NHL and included neutropenia (33%), thrombocytopenia (13%), and anemia (8%). Monitor blood counts after infusion. HYPOGAMMAGLOBULINEMIA B-cell aplasia and hypogammaglobulinemia can occur. Hypogammaglobulinemia was reported as an adverse reaction in 14% of all patients with NHL. Monitor immunoglobulin levels after treatment and manage using infection precautions, antibiotic prophylaxis, and immunoglobulin replacement. The safety of immunization with live viral vaccines during or following YESCARTA treatment has not been studied. Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during YESCARTA treatment, and until immune recovery following treatment. SECONDARY MALIGNANCIES Patients treated with YESCARTA may develop secondary malignancies. T cell malignancies have occurred following treatment of hematologic malignancies with BCMA- and CD19-directed genetically modified autologous T cell immunotherapies, including YESCARTA. Mature T cell malignancies, including CAR-positive tumors, may present as soon as weeks following infusion, and may include fatal outcomes. Monitor life-long for secondary malignancies. In the event that a secondary malignancy occurs, contact Kite at 1-844-454-KITE (5483) to obtain instructions on patient samples to collect for testing. EFFECTS ON ABILITY TO DRIVE AND USE MACHINES Due to the potential for neurologic events, including altered mental status or seizures, patients are at risk for altered or decreased consciousness or coordination in the 8 weeks following YESCARTA infusion. Advise patients to refrain from driving and engaging in hazardous occupations or activities, such as operating heavy or potentially dangerous machinery, during this initial period. ADVERSE REACTIONS The most common non-laboratory adverse reactions (incidence ≥ 20%) in patients with LBCL in ZUMA-7 included fever, CRS, fatigue, hypotension, encephalopathy, tachycardia, diarrhea, headache, musculoskeletal pain, nausea, febrile neutropenia, chills, cough, infection with unspecified pathogen, dizziness, tremor, decreased appetite, edema, hypoxia, abdominal pain, aphasia, constipation, and vomiting. The most common adverse reactions (incidence ≥ 20%) in patients with LBCL in ZUMA-1 included CRS, fever, hypotension, encephalopathy, tachycardia, fatigue, headache, decreased appetite, chills, diarrhea, febrile neutropenia, infections with pathogen unspecified, nausea, hypoxia, tremor, cough, vomiting, dizziness, constipation, and cardiac arrhythmias. The most common non-laboratory adverse reactions (incidence ≥ 20%) in patients with iNHL in ZUMA-5 included fever, CRS, hypotension, encephalopathy, fatigue, headache, infections with pathogen unspecified, tachycardia, febrile neutropenia, musculoskeletal pain, nausea, tremor, chills, diarrhea, constipation, decreased appetite, cough, vomiting, hypoxia, arrhythmia, and dizziness.
