New data show Roche's Itovebi significantly extended survival in a certain type of HR-positive advanced breast cancer
The Itovebi TM (inavolisib)-based regimen reduced the risk of death by more than 30% in people with PIK3CA -mutated HR-positive, HER2-negative advanced breast cancer, compared with palbociclib and fulvestrant alone 1 The PIK3CA mutation is found in approximately 40% of HR-positive advanced breast cancers and is associated with a poor prognosis 2,3 New data are being presented in an oral session at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting and published in the New England Journal of Medicine 1 Basel, 31 May 2025 – Roche (SIX: RO, ROG; OTCQX: RHHBY) announced today positive final results from the overall survival (OS) analysis of the phase III INAVO120 study. These data showed ItovebiTM (inavolisib), in combination with palbociclib (Ibrance®) and fulvestrant, reduced the risk of death by more than 30% compared with palbociclib and fulvestrant alone. This represents a statistically significant and clinically meaningful improvement in overall survival for people with PIK3CA -mutated, hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, endocrine-resistant, locally advanced or metastatic breast cancer.1 The results are being presented in an oral session at the 2025 American Society of Clinical Oncology (ASCO) Annual Meeting and simultaneously published in the New England Journal of Medicine (NEJM). 1 'For the first time, a PI3K pathway-targeted drug has shown it can help people with this breast cancer subtype live longer,' said Levi Garraway, M.D., Ph.D., Roche's Chief Medical Officer and Head of Global Product Development. 'Itovebi exemplifies our continued commitment to improve survival rates for people with this common PIK3CA mutation, for whom more effective treatment options are needed.' 'The landmark data for the inavolisib-based regimen showed not only a doubling in progression-free survival, but importantly that it extended lives and gave people more time without chemotherapy,' said Professor Nicholas Turner, Lead Study Author and Professor of Molecular Oncology at The Institute of Cancer Research, and Consultant Medical Oncologist at The Royal Marsden NHS Foundation Trust, London, United Kingdom. 'These results give us confidence that this regimen could become the new standard of care in the first-line setting, having demonstrated a substantial benefit on patient outcomes and quality of life.' The Itovebi-based regimen demonstrated a meaningful OS benefit compared with palbociclib and fulvestrant alone.1 The median OS was 34.0 months (95% CI: 28.4–44.8) for people in the Itovebi arm, compared with 27.0 months (95% CI: 22.8–38.7) in the palbociclib and fulvestrant arm (stratified hazard ratio [HR]=0.67; 95% CI: 0.48–0.94, p-value=0.0190 [boundary=0.0469]).1 The benefit seen in delaying cancer progression was maintained in the updated analysis, with the Itovebi-based regimen showing a consistent improvement in median progression free survival of 17.2 months versus 7.3 months (stratified HR=0.42; 95% CI: 0.32-0.55) in the comparator arm.1 The Itovebi-based regimen also led to a statistically significant improvement in objective response rate (the percentage of patients whose signs of cancer completely disappear or their tumours shrink significantly after treatment) and ad-hoc exploratory analyses showed it substantially delayed time to chemotherapy by approximately two years (stratified HR=0.43; 95% CI: 0.30-0.60).1 No new safety signals were observed at the time of the final OS analysis, with a low discontinuation due to adverse events supporting good tolerability.1 The Itovebi-based regimen is approved in the United States, Switzerland, Canada, Australia, United Arab Emirates and China. In May, it received a positive opinion from the European Medicines Agency's Committee for Medicinal Products for Human Use (CHMP), with a final decision regarding the approval expected from the European Commission in the near future. Data from the INAVO120 study are currently under review with other global health authorities. Beyond INAVO120, Itovebi is currently being investigated in three company-sponsored phase III studies (INAVO121, INAVO122, INAVO123), all in PIK3CA -mutated, locally advanced or metastatic breast cancer in various combinations.4-7 We are exploring additional studies in breast cancer and other tumour types with the hope of providing the benefit of this targeted therapy to more people with PIK3CA mutations. About Itovebi TM (inavolisib) Itovebi is an oral, targeted treatment that has been shown to provide well-tolerated and durable disease control in people with PIK3CA -mutated, hormone receptor-positive, human epidermal growth factor receptor 2-negative, advanced breast cancer, who often have a poor prognosis and are in urgent need of new treatment options.2,3,8 Itovebi has been designed to help minimise the overall burden and toxicity of treatment and is differentiated from other PI3K inhibitors due to its high potency and specificity for the PI3K alpha isoform versus other isoforms, and unique mechanism of action that facilitates the degradation of mutated PI3K alpha.9,10 About the INAVO120 study The INAVO120 study [NCT04191499] is a phase III, randomised, double-blind, placebo-controlled study evaluating the efficacy and safety of Itovebi™ (inavolisib) in combination with palbociclib and fulvestrant versus placebo plus palbociclib and fulvestrant in people with PIK3CA -mutated, hormone receptor (HR)-positive, human epidermal growth factor receptor 2 (HER2)-negative, locally advanced or metastatic breast cancer whose disease progressed during treatment or within 12 months of completing adjuvant endocrine therapy and who have not received prior systemic therapy for metastatic disease.4 The study included 325 patients, who were randomly assigned to either the investigational or control treatment arm.4 The primary endpoint is progression-free survival, as assessed by investigators, defined as the time from randomisation in the clinical trial to the time when the disease progresses, or a patient dies from any cause.4 Secondary endpoints include overall survival, objective response rate, and clinical benefit rate.4 Beyond INAVO120, Itovebi is currently being investigated in three additional company-sponsored phase III clinical studies in PIK3CA -mutated locally advanced or metastatic breast cancer in various combinations:5-7 in combination with fulvestrant versus alpelisib plus fulvestrant in HR-positive/HER2-negative breast cancer post cyclin-dependent kinase 4/6 (CDK4/6) inhibitor and endocrine combination therapy (INAVO121; NCT05646862). in combination with pertuzumab plus trastuzumab for subcutaneous injection (SC) versus pertuzumab plus trastuzumab for SC and optional physician's choice of endocrine therapy as a maintenance treatment in HER2-positive disease (INAVO122; NCT05894239). in combination with CDK4/6 inhibitor and letrozole versus placebo plus a CDK4/6 inhibitor and letrozole in the first-line setting in PIK3CA -mutated HR-positive/HER2-negative, endocrine-sensitive breast cancer (INAVO123; NCT06790693). About hormone receptor (HR)-positive breast cancer HR-positive breast cancer is the most prevalent type of all breast cancers, accounting for approximately 70% of cases.11,12 A defining feature of HR-positive breast cancer is that its tumour cells have receptors that attach to one or both hormones – oestrogen or progesterone – which can contribute to tumour growth. People diagnosed with HR-positive metastatic breast cancer often face the risk of disease progression and treatment side effects, creating a need for additional treatment options.12-14 The PI3K signalling pathway is commonly dysregulated in HR-positive breast cancer, often due to activating PIK3CA mutations, which have been identified as a potential mechanism of intrinsic resistance to standard of care endocrine therapy in combination with cyclin-dependent kinase 4/6 inhibitors.3 About Roche in breast cancer Roche has been advancing breast cancer research for more than 30 years with the goal of helping as many people with the disease as possible.

SunPower says all shareholder proposals pass at Annual Meeting
SunPower (SPWR) held its Annual Meeting yesterday, May 29th at 11:00 a.m. Pacific Time. All 12 SunPower proposals won with votes of 95% or higher, including: 1. the re-election of our 11 Board members, 2. re-hiring BDO as our auditor, and 3. the approval of the employee stock plan. SPWR chairman and CEO, T.J. Rodgers, said, 'First and foremost, I thank our shareholders again for their great financial support in approving the stockholder plan proposal with a 96% vote. We have already transformed the company with our SPWR asset acquisition, and you just approved the shares – the standard new-hire shares – for about 1,000 SunPower employees that joined us as, in effect, founders, and swelled our ranks by 10x and our revenue by 14.7x. In addition, you also pre-approved the hiring shares for the next acquisition, which we are working on vigorously. And the ITC phase-out in the news today will make our next acquisitions easier. I have also run multiple financial scenarios for SPWR on the impact of the ITC phase-out. I do not see any possible ITC problem for the rest of this year that could cause SunPower's revenue to drop enough to make us unprofitable, let alone have a serious financial issue. The 2026 ITC phase-out is still being debated, but in the worst case, an abrupt ITC shutdown at the end of Q4'25, we would have to suffer a quarterly revenue decline to below our breakeven point of $72M, an unlikely event. I wanted investors to know that now, while I am preparing a deeper presentation on the ITC issue to be presented on Thursday, June 5, 2025.'

In Largest Molecular Residual Disease (MRD) Study in Colon Cancer, Guardant Reveal Testing Prior to Chemotherapy Provides Robust Stratification for Risk of Disease Recurrence and Survival to Enable Timely Treatment Decisions
PALO ALTO, Calif.--(BUSINESS WIRE)--Guardant Health, Inc. (Nasdaq: GH), a leading precision oncology company, and its research collaborators today presented results of the largest study to date evaluating circulating tumor DNA (ctDNA) in colon cancer prior to chemotherapy, demonstrating the ability of the Guardant Reveal™ test to stratify the risk of disease recurrence and overall survival, and thus inform treatment decisions after surgery. Data from the phase III trial of FOLFOX-based adjuvant chemotherapy (NCCTG N0147) involving over 2,000 patients with stage III colon cancer with median follow-up of 6.1 years were presented at the 2025 American Society for Clinical Oncology (ASCO) Annual Meeting. Results demonstrated that circulating tumor DNA detected in the bloodstream after cancer surgery and prior to the start of adjuvant therapy, using the Guardant Reveal test, is a strong predictor of the risk of disease recurrence and poorer survival, and suggest the potential for ctDNA testing to improve decision-making at a critical time point for post-operative chemotherapy. Specifically: Among patients with post-surgical ctDNA detected, 62.6% had the cancer return within 3 years, despite having had adjuvant chemotherapy, while only 15.4% of patients with undetectable ctDNA recurred in the same period. The level of ctDNA, or tumor fraction, showed promise in identifying individuals who are less likely to clear residual disease with adjuvant treatment. 'Thirty percent of patients with stage III colon cancer will relapse after surgery, despite having standard adjuvant chemotherapy,' said Frank Sinicrope, MD, professor of oncology and medicine at Mayo Clinic and principal investigator for the study. 'In this study, we demonstrate that analysis of postsurgical ctDNA can improve the prediction of disease recurrence over standard staging criteria, which may help guide patient management and follow-up. These data further support the routine use of ctDNA in management of stage III colon cancer patients.' 'With the Guardant Reveal test, a simple blood draw can be used to identify colorectal cancer patients who have molecular residual disease and are most likely to benefit from adjuvant therapy,' said Helmy Eltoukhy, Guardant Health chairman and co-CEO. 'This large study confirms the test's ability to identify high risk of cancer returning and support oncologists in making more informed therapeutic decisions to help improve patient outcomes.' The full abstract for the presentation can be found on the ASCO website. About Guardant Reveal Guardant Reveal, which runs on the Guardant Infinity™ smart liquid biopsy platform, is a blood test that uses epigenomic (methylation) analysis to detect circulating tumor DNA, a marker of minimal residual disease, to predict cancer recurrence, helping to guide clinical decisions after surgery or chemotherapy. The test is covered by Medicare for patients with colorectal cancer in the early post-surgical setting and for surveillance testing to monitor for disease recurrence after curative intent treatment. About Molecular Residual Disease Molecular residual disease refers to a subclinical measure of cancer burden that remains during and following treatment. A patient's MRD status is a reliable indicator of clinical outcome and response to therapy and can be used for risk stratification and to guide treatment options when used in conjunction with other clinical data. About Guardant Health Guardant Health is a leading precision oncology company focused on guarding wellness and giving every person more time free from cancer. Founded in 2012, Guardant is transforming patient care and accelerating new cancer therapies by providing critical insights into what drives disease through its advanced blood and tissue tests, real-world data and AI analytics.

ENHERTU ® Reduced the Risk of Death by 30% Versus Ramucirumab Plus Paclitaxel as a Second-Line Therapy in Patients with HER2 Positive Unresectable or Metastatic Gastric Cancer in DESTINY-Gastric04 Phase 3 Trial
TOKYO & BASKING RIDGE, N.J.--(BUSINESS WIRE)--Positive results from the DESTINY-Gastric04 phase 3 trial showed ENHERTU ® (trastuzumab deruxtecan) demonstrated a statistically significant and clinically meaningful improvement in overall survival (OS) compared to ramucirumab plus paclitaxel in patients with second-line HER2 positive (IHC 3+ or IHC 2+/ISH+) unresectable and/or metastatic gastric or gastroesophageal junction (GEJ) adenocarcinoma. Results will be presented today as a late-breaking oral presentation (LBA #4002) at the 2025 American Society of Clinical Oncology (#ASCO25) Annual Meeting and simultaneously published in The New England Journal of Medicine. ENHERTU is a specifically engineered HER2 directed DXd antibody drug conjugate (ADC) discovered by Daiichi Sankyo (TSE: 4568) and being jointly developed and commercialized by Daiichi Sankyo and AstraZeneca (LSE/STO/Nasdaq: AZN). In the primary endpoint analysis of OS, ENHERTU reduced the risk of death by 30% versus ramucirumab plus paclitaxel (hazard ratio [HR]: 0.70; confidence interval [CI]: 0.55-0.90; p=0.0044). Median OS was 14.7 months with ENHERTU (n=246) versus 11.4 months with ramucirumab plus paclitaxel (n=248). In the secondary endpoint analysis of progression-free survival (PFS), ENHERTU demonstrated a 26% reduction in the risk of disease progression or death versus ramucirumab plus paclitaxel (HR: 0.74; 95% CI: 0.59-0.92; p=0.0074) as assessed by investigator. Median PFS was 6.7 months with ENHERTU versus 5.6 months with ramucirumab plus paclitaxel. A confirmed objective response rate (ORR) of 44.3% (95% CI: 37.8-50.9) was seen in patients treated with ENHERTU with seven complete responses (CR) and 97 partial responses (PR) versus an ORR of 29.1% (95% CI: 23.4-35.3) with three CRs and 66 PRs in the ramucirumab plus paclitaxel arm (p=0.0006). Median duration of response (DOR) was 7.4 months (95% CI: 5.7-10.1) in the ENHERTU arm and 5.3 months (95% CI: 4.1-5.7) in the ramucirumab plus paclitaxel arm. Disease control rate (DCR) was 91.9% (95% CI: 87.7-95.1) with ENHERTU versus 75.9% (95% CI: 70.0-81.2) with ramucirumab plus paclitaxel. Improvements in OS and PFS with ENHERTU were consistent across subgroups. 'Gastric cancer is particularly challenging to treat, especially in the advanced stages where the five-year survival rate remains low,' said Kohei Shitara, MD, Chief, Department of Gastrointestinal Oncology, National Cancer Center Hospital East, Chiba, Japan and lead investigator in the DESTINY-Gastric04 trial. 'The superior overall survival demonstrated in DESTINY-Gastric04 confirms that ENHERTU could become the global standard of care in the second-line metastatic setting of HER2 positive gastric cancer or gastroesophageal junction cancer.' The safety profile of ENHERTU in DESTINY-Gastric04 was consistent with previous gastric cancer clinical trials with no new safety concerns identified. The most common grade 3 or higher treatment related adverse events occurring in patients treated with ENHERTU were neutropenia (28.7%), anemia (13.9%), thrombocytopenia (8.6%), leukopenia (7.4%) and fatigue (7.0%). Interstitial lung disease (ILD) or pneumonitis occurred in 13.9% of patients treated with ENHERTU and 1.3% treated in the ramucirumab plus paclitaxel arm. In the ENHERTU arm, the majority of ILD or pneumonitis events were low grade (grade 1 [n=7; 2.9%] or grade 2 [n=26; 10.7%]) except for one grade 3 ILD event (0.4%) as determined by an independent adjudication committee. In the ramucirumab plus paclitaxel arm, there were two grade 3 (0.9%) and one grade 5 (0.4%) ILD events. 'ENHERTU continues to deliver impressive results with these new data from DESTINY-Gastric04, which represent the first time a HER2 directed medicine has demonstrated a survival benefit in a randomized phase 3 trial in the second-line HER2 positive metastatic gastric cancer setting,' said Ken Takeshita, MD, Global Head, R&D, Daiichi Sankyo. 'Similar to our strategy in other tumor types, we continue to pursue the development of ENHERTU in earlier stages of gastric cancer and have recently initiated phase 3 trials evaluating ENHERTU as part of a combination regimen as a first-line treatment in patients HER2 positive metastatic disease.' 'Patients with HER2 positive metastatic gastric cancer who experience progression after first-line treatment have historically faced poor outcomes,' said Cristian Massacesi, MD, Chief Medical Officer and Oncology Chief Development Officer, AstraZeneca. 'These results showed that ENHERTU reduced the risk of death by nearly one-third in patients with previously treated HER2 positive metastatic gastric cancer, reinforcing the benefit of ENHERTU in this setting.' ENHERTU is currently approved in more than 70 countries in the second-line or third-line metastatic setting of HER2 positive gastric cancer based on DESTINY-Gastric01, a randomized phase 2 trial, and DESTINY-Gastric02 and DESTINY-Gastric06, two single-arm phase 2 trials. Daiichi Sankyo and AstraZeneca are currently evaluating ENHERTU in the first-line metastatic setting through the DESTINY-Gastric05 and ARETEMIDE-Gastric01 phase 3 trials. The majority of patients in the DESTINY-Gastric04 trial had received no prior treatment with an immune checkpoint inhibitor (84.1% in the ENHERTU arm and 84.7% in the ramucirumab plus paclitaxel arm) and had two or more metastatic sites (70.3% in the ENHERTU arm and 69.8% in the ramucirumab plus paclitaxel arm). Median duration of follow-up was 16.8 months in the ENHERTU arm and 14.4 months in the ramucirumab plus paclitaxel arm. Median treatment duration was 5.4 months (range: 0.7-30.3) with ENHERTU and 4.6 months (range: 0.9-34.9) with ramucirumab plus paclitaxel. Of the patients that discontinued treatment from the ramucirumab plus paclitaxel arm, 52 (21.0%) proceeded to receive ENHERTU and 12 (4.8%) disitamab vedotin post-trial. As of the data cut-off of October 24, 2024, 18.9% of patients receiving ENHERTU and 18.5% receiving ramucirumab plus paclitaxel remained on study treatment.

The primary endpoint is OS. Secondary endpoints include investigator-assessed progression-free survival, objective response rate, duration of response, disease control rate and safety. In March 2025, an Independent Data Monitoring Committee recommended unblinding DESTINY-Gastric04 based on the superior efficacy of ENHERTU seen at a planned interim analysis. DESTINY-Gastric04 enrolled 494 patients in Asia, Europe and South America. For more information about the trial, visit About HER2 Positive Gastric Cancer Gastric (stomach) cancer is the fifth most common cancer worldwide and the fifth leading cause of cancer-related death. 1 Approximately one million cases of gastric cancer were diagnosed in 2022. 1 Gastric cancer is associated with a poor prognosis, particularly in advanced stages of the disease where the five-year survival rate is 5% to 10%. 2 HER2 is a tyrosine kinase receptor growth-promoting protein expressed on the surface of many types of tumors, including gastric cancer. 3 Approximately one in five gastric cancers are considered HER2 positive. 3,4 Prior to the results of the DESTINY-Gastric04 trial of ENHERTU, no other HER2 directed medicine has demonstrated a survival benefit in the second-line metastatic setting in a randomized clinical trial. 5 About ENHERTU ENHERTU (trastuzumab deruxtecan; fam-trastuzumab deruxtecan-nxki in the U.S. only) is a HER2 directed ADC. Designed using Daiichi Sankyo's proprietary DXd ADC Technology, ENHERTU is the lead ADC in the oncology portfolio of Daiichi Sankyo and the most advanced program in AstraZeneca's ADC scientific platform. ENHERTU consists of a HER2 monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers. ENHERTU (5.4 mg/kg) is approved in more than 80 countries worldwide for the treatment of adult patients with unresectable or metastatic HER2 positive (immunohistochemistry [IHC] 3+ or in-situ hybridization (ISH)+) breast cancer who have received a prior anti-HER2-based regimen, either in the metastatic setting or in the neoadjuvant or adjuvant setting, and have developed disease recurrence during or within six months of completing therapy based on the results from the DESTINY-Breast03 trial.

Warnings and Precautions Interstitial Lung Disease / Pneumonitis Severe, life-threatening, or fatal interstitial lung disease (ILD), including pneumonitis, can occur in patients treated with ENHERTU. A higher incidence of Grade 1 and 2 ILD/pneumonitis has been observed in patients with moderate renal impairment. Advise patients to immediately report cough, dyspnea, fever, and/or any new or worsening respiratory symptoms. Monitor patients for signs and symptoms of ILD. Promptly investigate evidence of ILD. Evaluate patients with suspected ILD by radiographic imaging. Consider consultation with a pulmonologist. For asymptomatic ILD/pneumonitis (Grade 1), interrupt ENHERTU until resolved to Grade 0, then if resolved in ≤28 days from date of onset, maintain dose. If resolved in >28 days from date of onset, reduce dose 1 level. Consider corticosteroid treatment as soon as ILD/pneumonitis is suspected (e.g., ≥0.5 mg/kg/day prednisolone or equivalent). For symptomatic ILD/pneumonitis (Grade 2 or greater), permanently discontinue ENHERTU. Promptly initiate systemic corticosteroid treatment as soon as ILD/pneumonitis is suspected (e.g., ≥1 mg/kg/day prednisolone or equivalent) and continue for at least 14 days followed by gradual taper for at least 4 weeks. HER2-Positive, HER2-Low, and HER2-Ultralow Metastatic Breast Cancer, HER2-Mutant NSCLC, and Solid Tumors (Including IHC 3+) (5.4 mg/kg) In patients with metastatic breast cancer, HER2-mutant NSCLC, and other solid tumors treated with ENHERTU 5.4 mg/kg, ILD occurred in 12% of patients. Median time to first onset was 5.5 months (range: 0.9 to 31.5). Fatal outcomes due to ILD and/or pneumonitis occurred in 0.9% of patients treated with ENHERTU. HER2-Positive Locally Advanced or Metastatic Gastric Cancer (6.4 mg/kg) In patients with locally advanced or metastatic HER2-positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg, ILD occurred in 10% of patients. Median time to first onset was 2.8 months (range: 1.2 to 21). Neutropenia Severe neutropenia, including febrile neutropenia, can occur in patients treated with ENHERTU. Monitor complete blood counts prior to initiation of ENHERTU and prior to each dose, and as clinically indicated. For Grade 3 neutropenia (Absolute Neutrophil Count [ANC] <1.0 to 0.5 x 10 9 /L), interrupt ENHERTU until resolved to Grade 2 or less, then maintain dose. For Grade 4 neutropenia (ANC <0.5 x 10 9 /L), interrupt ENHERTU until resolved to Grade 2 or less, then reduce dose by 1 level. For febrile neutropenia (ANC <1.0 x 10 9 /L and temperature >38.3° C or a sustained temperature of ≥38° C for more than 1 hour), interrupt ENHERTU until resolved, then reduce dose by 1 level. HER2-Positive, HER2-Low, and HER2-Ultralow Metastatic Breast Cancer, HER2-Mutant NSCLC, and Solid Tumors (Including IHC 3+) (5.4 mg/kg) In patients with metastatic breast cancer, HER2-mutant NSCLC, and other solid tumors treated with ENHERTU 5.4 mg/kg, a decrease in neutrophil count was reported in 65% of patients. Nineteen percent had Grade 3 or 4 decreased neutrophil count. Median time to first onset of decreased neutrophil count was 22 days (range: 2 to 939). Febrile neutropenia was reported in 1.2% of patients. HER2-Positive Locally Advanced or Metastatic Gastric Cancer (6.4 mg/kg) In patients with locally advanced or metastatic HER2-positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg, a decrease in neutrophil count was reported in 72% of patients. Fifty-one percent had Grade 3 or 4 decreased neutrophil count. Median time to first onset of decreased neutrophil count was 16 days (range: 4 to 187). Febrile neutropenia was reported in 4.8% of patients. Left Ventricular Dysfunction Patients treated with ENHERTU may be at increased risk of developing left ventricular dysfunction. Left ventricular ejection fraction (LVEF) decrease has been observed with anti-HER2 therapies, including ENHERTU. Assess LVEF prior to initiation of ENHERTU and at regular intervals during treatment as clinically indicated. Manage LVEF decrease through treatment interruption. When LVEF is >45% and absolute decrease from baseline is 10-20%, continue treatment with ENHERTU. When LVEF is 40-45% and absolute decrease from baseline is 20%, interrupt ENHERTU and repeat LVEF assessment within 3 weeks. If LVEF of 20% is confirmed, permanently discontinue ENHERTU. Permanently discontinue ENHERTU in patients with symptomatic congestive heart failure. Treatment with ENHERTU has not been studied in patients with a history of clinically significant cardiac disease or LVEF <50% prior to initiation of treatment. HER2-Positive, HER2-Low, and HER2-Ultralow Metastatic Breast Cancer, HER2-Mutant NSCLC, and Solid Tumors (Including IHC 3+) (5.4 mg/kg) In patients with metastatic breast cancer, HER2-mutant NSCLC, and other solid tumors treated with ENHERTU 5.4 mg/kg, LVEF decrease was reported in 4.6% of patients, of which 0.6% were Grade 3 or 4. HER2-Positive Locally Advanced or Metastatic Gastric Cancer (6.4 mg/kg) In patients with locally advanced or metastatic HER2-positive gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg, no clinical adverse events of heart failure were reported; however, on echocardiography, 8% were found to have asymptomatic Grade 2 decrease in LVEF. Embryo-Fetal Toxicity ENHERTU can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risks to a fetus. Verify the pregnancy status of females of reproductive potential prior to the initiation of ENHERTU. Advise females of reproductive potential to use effective contraception during treatment and for 7 months after the last dose of ENHERTU. Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ENHERTU and for 4 months after the last dose of ENHERTU. Additional Dose Modifications Thrombocytopenia For Grade 3 thrombocytopenia (platelets <50 to 25 x 10 9 /L) interrupt ENHERTU until resolved to Grade 1 or less, then maintain dose. For Grade 4 thrombocytopenia (platelets <25 x 10 9 /L) interrupt ENHERTU until resolved to Grade 1 or less, then reduce dose by 1 level.

Use in Specific Populations Pregnancy: ENHERTU can cause fetal harm when administered to a pregnant woman. Advise patients of the potential risks to a fetus. There are clinical considerations if ENHERTU is used in pregnant women, or if a patient becomes pregnant within 7 months after the last dose of ENHERTU. Lactation: There are no data regarding the presence of ENHERTU in human milk, the effects on the breastfed child, or the effects on milk production. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with ENHERTU and for 7 months after the last dose. Females and Males of Reproductive Potential: Pregnancy testing: Verify pregnancy status of females of reproductive potential prior to initiation of ENHERTU. Contraception: Females: ENHERTU can cause fetal harm when administered to a pregnant woman. Advise females of reproductive potential to use effective contraception during treatment with ENHERTU and for 7 months after the last dose. Males: Advise male patients with female partners of reproductive potential to use effective contraception during treatment with ENHERTU and for 4 months after the last dose. Infertility: ENHERTU may impair male reproductive function and fertility. Pediatric Use: Safety and effectiveness of ENHERTU have not been established in pediatric patients. Geriatric Use: Of the 1741 patients with HER2-positive, HER2-low, or HER2-ultralow breast cancer treated with ENHERTU 5.4 mg/kg, 24% were ≥65 years and 4.9% were ≥75 years. No overall differences in efficacy within clinical studies were observed between patients ≥65 years of age compared to younger patients. There was a higher incidence of Grade 3-4 adverse reactions observed in patients aged ≥65 years (61%) as compared to younger patients (52%). Of the 101 patients with HER2-mutant unresectable or metastatic NSCLC treated with ENHERTU 5.4 mg/kg, 40% were ≥65 years and 8% were ≥75 years. No overall differences in efficacy or safety were observed between patients ≥65 years of age compared to younger patients. Of the 125 patients with HER2-positive locally advanced or metastatic gastric or GEJ adenocarcinoma treated with ENHERTU 6.4 mg/kg in DESTINY-Gastric01, 56% were ≥65 years and 14% were ≥75 years. No overall differences in efficacy or safety were observed between patients ≥65 years of age compared to younger patients. Of the 192 patients with HER2-positive (IHC 3+) unresectable or metastatic solid tumors treated with ENHERTU 5.4 mg/kg in DESTINY-PanTumor02, DESTINY-Lung01, or DESTINY-CRC02, 39% were ≥65 years and 9% were ≥75 years. No overall differences in efficacy or safety were observed between patients ≥65 years of age compared to younger patients. Renal Impairment: A higher incidence of Grade 1 and 2 ILD/pneumonitis has been observed in patients with moderate renal impairment. Monitor patients with moderate renal impairment more frequently. The recommended dosage of ENHERTU has not been established for patients with severe renal impairment (CLcr <30 mL/min). Hepatic Impairment: In patients with moderate hepatic impairment, due to potentially increased exposure, closely monitor for increased toxicities related to the topoisomerase inhibitor, DXd. The recommended dosage of ENHERTU has not been established for patients with severe hepatic impairment (total bilirubin >3 times ULN and any AST).
