Results from the Phase 2 RedirecTT-1 study demonstrate deep responses with 78.9 percent overall response rate through dual targeting of GPRC5D and BCMA
Data signal potential of novel, off-the-shelf approach in patients with extramedullary disease who face significant unmet needs
MILAN, June 15, 2025 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) announced today new results from the Phase 2 RedirecTT-1 study evaluating the investigational combination of TALVEY® (talquetamab-tgvs), the first U.S. Food and Drug Administration (FDA)-approved GPRC5D-directed bispecific antibody, and TECVAYLI® (teclistamab-cqyv), the first FDA-approved BCMA-directed bispecific antibody. The results show a high overall response rate (ORR) with durability in patients with triple-class exposed (TCE) relapsed/refractory multiple myeloma (RRMM) who have true extramedullary disease (EMD). EMD is defined as soft tissue/organ-associated plasmacytomas with no contact to bony structures as per International Myeloma Working Group (IMWG) criteria.1 RedirecTT-1 is the largest study dedicated to patients with EMD to date. These data were featured in a late-breaking oral presentation (Abstract #LB4001 ) at the 2025 European Hematology Association (EHA) Congress.
EMD represents an aggressive form of multiple myeloma and occurs when myeloma cells spread and form tumors (plasmacytomas) elsewhere in the body, such as in soft tissues and organs. These patients often face limited treatment options and worse outcomes due to the complexity of the disease, including tumor heterogeneity, resulting in low ORRs and rapid relapses with current standard therapies. On average, TCE RRMM patients with EMD have an ORR of less than 40 percent and a median progression-free survival (PFS) of less than 6 months.2
'The investigational combination of TALVEY and TECVAYLI has demonstrated deep, durable responses in patients with relapsed or refractory multiple myeloma, and now shows great promise in those with extramedullary myeloma, where standard therapies often fall short,' said Yael Cohen, M.D., Head of Myeloma Unit, Tel-Aviv Sourasky Medical Center, Tel-Aviv, Israel.* 'Dual targeting of GPRC5D and BCMA may lead to a higher ORR and greater depth of response by mitigating target antigen-related escape. The RedirecTT-1 trial shows the power of this novel dual-targeting combination approach as a potential treatment option for patients with this disease.'
The Phase 2 RedirecTT-1 study enrolled 90 patients with TCE RRMM with true EMD. Of these patients, 84.4 percent were triple-class refractory, 35.6 percent were penta-drug refractory, 20 percent had previously received BCMA CAR-T therapy, and 8.9 percent had previously received a bispecific antibody.3 The investigational combination of TALVEY® plus TECVAYLI® led to a high ORR of 78.9 percent (95 percent confidence interval [CI]; 69.0–86.8), with more than half of patients (54.4 percent) achieving complete response or better.3 High responses were observed even in patients exposed to prior BCMA CAR-T or anti-FcRH5 bispecific antibodies (83.3 percent ORR; 58.6-96.4 and 75 percent ORR; 34.9-96.8, respectively).3 Among responders, 66.2 percent remained in response at the data cutoff, with a median follow-up of 13.4 months, signaling deep and durable responses.3 Treatment with the combination resulted in 61 percent of patients progression free and alive at one year.3 Additionally, the combination led to durable responses, with 64.1 percent of patients maintaining response (median duration of response: 13.8 months) and 74.5 percent of patients alive at one year, while median overall survival was not yet reached.3
'Patients with extramedullary myeloma, especially those who have exhausted prior therapies, need more effective treatment options,' said Jordan Schecter, M.D., Vice President, Disease Area Leader, Multiple Myeloma, Johnson & Johnson Innovative Medicine. 'Our first-in-class bispecific antibodies TALVEY and TECVAYLI have transformed treatment for relapsed or refractory multiple myeloma. The RedirecTT-1 study underscores our commitment to advancing innovative therapies that attack the disease in different ways by building combinable and complementary regimens.'
The safety profile of the combination was consistent with previous reports of TALVEY® and TECVAYLI® as monotherapies, with no new safety signals identified.3 Patients were given the option to switch to once a month dosing, potentially contributing to improved tolerability. Rates of discontinuation were low with the treatment combination of TALVEY® and TECVAYLI® due to adverse events (AEs).3 Four participants discontinued TALVEY® only.3 Reports of CRS and immune effector cell-associated neurotoxicity syndrome (ICANS) were mostly low grade.3 Of the ten patients who had Grade 5 AEs (11.1 percent), five were due to infections and five were unrelated.3 The rates of severe infection were similar to those observed with BCMA bispecific antibody monotherapies.3
About TALVEY®
TALVEY® (talquetamab-tgvs) received approval from the U.S. FDA in August 2023 as a first-in-class GPRC5D-targeting bispecific antibody for the treatment of adult patients with relapsed or refractory multiple myeloma who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 antibody.4 Since FDA approval, more than 4,900 patients have been treated worldwide with TALVEY®. The European Commission (EC) granted conditional marketing authorization (CMA) of TALVEY® ▼ (talquetamab) in August 2023 as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma (RRMM) who have received at least three prior therapies, including an immunomodulatory agent, a proteasome inhibitor, and an anti-CD38 antibody and have demonstrated disease progression on the last therapy.5
TALVEY® is a bispecific T-cell engaging antibody that binds to the CD3 receptor expressed on the surface of T-cells and G protein-coupled receptor class C group 5 member D (GPRC5D), a novel multiple myeloma target which is highly expressed on the surface of multiple myeloma cells and nonmalignant plasma cells, as well as some healthy tissues such as epithelial cells of the skin and tongue.
About TECVAYLI®
TECVAYLI® (teclistamab-cqyv) received approval from the U.S. FDA in October 2022 as an off-the-shelf (or ready-to-use) antibody that is administered as a subcutaneous treatment for adult patients with relapsed or refractory multiple myeloma (RRMM) who have received at least four prior lines of therapy, including a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 antibody.[6] Since FDA approval, more than 15,900 patients have been treated worldwide with TECVAYLI®. The European Commission (EC) granted TECVAYLI® conditional marketing authorization (CMA) in August 2022 as monotherapy for the treatment of adult patients with RRMM who have received at least three prior therapies, including a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 antibody, and have demonstrated disease progression since the last therapy. In August 2023, the EC granted the approval of a Type II variation application for TECVAYLI®, providing the option for a reduced dosing frequency of 1.5 mg/kg every two weeks (Q2W) in patients who have achieved a complete response (CR) or better for a minimum of six months. TECVAYLI® is a first-in-class, bispecific T-cell engager antibody therapy that uses innovative science to activate the immune system by binding to the CD3 receptor expressed on the surface of T-cells and to the B-cell maturation antigen (BCMA) expressed on the surface of multiple myeloma cells and some healthy B-lineage cells. In February 2024, the U.S. FDA approved the supplemental Biologics License Application (sBLA) for TECVAYLI® for a reduced dosing frequency of 1.5 mg/kg every two weeks in patients with relapsed or refractory multiple myeloma who have achieved and maintained a CR or better for a minimum of six months.

About multiple myeloma
Multiple myeloma is an incurable blood cancer that affects a type of white blood cell called plasma cells, which are found in the bone marrow.7 In multiple myeloma, these plasma cells proliferate and spread rapidly and replace normal cells in the bone marrow with tumors.8 Multiple myeloma is the third most common blood cancer worldwide and remains an incurable disease.9 In 2024, it was estimated that more than 35,000 people will be diagnosed with multiple myeloma in the U.S., and more than 12,000 people would die from the disease.10 People living with multiple myeloma have a 5-year survival rate of 59.8 percent.[11] While some people diagnosed with multiple myeloma initially have no symptoms, most patients are diagnosed due to symptoms that can include bone fracture or pain, low red blood cell counts, tiredness, high calcium levels and kidney problems or infections.12,13

Because of the risk of CRS and neurologic toxicity, including ICANS, TALVEY® is available only through a restricted program called the TECVAYLI® and TALVEY® Risk Evaluation and Mitigation Strategy (REMS).
CONTRAINDICATIONS: None.
WARNINGS AND PRECAUTIONS
Cytokine Release Syndrome (CRS): TALVEY® can cause cytokine release syndrome, including life-threatening or fatal reactions. In the clinical trial, CRS occurred in 76% of patients who received TALVEY® at the recommended dosages, with Grade 1 CRS occurring in 57% of patients, Grade 2 in 17%, and Grade 3 in 1.5%. Recurrent CRS occurred in 30% of patients. Most events occurred following step-up dose 1 (29%) or step-up dose 2(44%) at the recommended dosages. CRS occurred in 33% of patients with step-up dose 3 in the biweekly dosing schedule (N=153). CRS occurred in 30% of patients with the first 0.4 mg/kg treatment dose and in 12% of patients treated with the first 0.8 mg/kg treatment dose. The CRS rate for both dosing schedules combined was less than 3% for each of the remaining doses in Cycle 1 and less than 3% cumulatively from Cycle 2 onward. The median time to onset of CRS was 27 (range: 0.1 to 167) hours from the last dose, and the median duration was 17 (range: 0 to 622) hours. Clinical signs and symptoms of CRS include but are not limited to pyrexia, hypotension, chills, hypoxia, headache, and tachycardia. Potentially life-threatening complications of CRS may include cardiac dysfunction, acute respiratory distress syndrome, neurologic toxicity, renal and/or hepatic failure, and disseminated intravascular coagulation (DIC).
Initiate therapy with step-up dosing and administer pre-treatment medications (corticosteroids, antihistamine, and antipyretics) prior to each dose of TALVEY® in the step-up dosing schedule to reduce the risk of CRS. Monitor patients following administration accordingly. In patients who experience CRS, pre-treatment medications should be administered prior to the next TALVEY® dose.
Counsel patients to seek medical attention should signs or symptoms of CRS occur. At the first sign of CRS, immediately evaluate patient for hospitalization and institute treatment with supportive care based on severity, and consider further management per current practice guidelines. Withhold TALVEY® until CRS resolves or permanently discontinue based on severity.
Neurologic Toxicity including ICANS: TALVEY® can cause serious, or life-threatening neurologic toxicity or fatal neurologic toxicity including immune effector cell-associated neurotoxicity syndrome (ICANS), including fatal reactions. In the clinical trial, neurologic toxicity, including ICANS, occurred in 55% of patients who received the recommended dosages, with Grade 3 or 4 neurologic toxicity occurring in 6% of patients. The most frequent neurologic toxicities were headache (20%), encephalopathy (15%), sensory neuropathy (14%), and motor dysfunction (10%).
ICANS was reported in 9% of 265 patients where ICANS was collected and who received the recommended dosages. Recurrent ICANS occurred in 3% of patients. Most patients experienced ICANS following step-up dose 1 (3%), step-up dose 2 (3%), step-up dose 3 of the biweekly dosing schedule (1.8%), or the initial treatment dose of the weekly dosing schedule (2.6%) (N=156) or the biweekly dosing schedule (3.7%) (N=109). The median time to onset of ICANS was 2.5 (range: 1 to 16) days after the most recent dose with a median duration of 2 (range: 1 to 22) days. The onset of ICANS can be concurrent with CRS, following resolution of CRS, or in the absence of CRS. Clinical signs and symptoms of ICANS may include but are not limited to confusional state, depressed level of consciousness, disorientation, somnolence, lethargy, and bradyphrenia.
Monitor patients for signs and symptoms of neurologic toxicity during treatment and treat promptly. At the first sign of neurologic toxicity, including ICANS, immediately evaluate the patient and provide supportive care based on severity. Withhold or permanently discontinue TALVEY® based on severity and consider further management per current practice guidelines [see Dosage and Administration (2.5)].
Due to the potential for neurologic toxicity, patients receiving TALVEY® are at risk of depressed level of consciousness. Advise patients to refrain from driving or operating heavy or potentially dangerous machinery during the step-up dosing schedule and for 48 hours after completion of the step-up dosing schedule, and in the event of new onset of any neurological symptoms, until symptoms resolve.
TECVAYLI® and TALVEY® REMS: TALVEY® is available only through a restricted program under a REMS, called the TECVAYLI® and TALVEY® REMS because of the risks of CRS and neurologic toxicity, including ICANS.

The most frequent oral toxicities were dysgeusia (49%), dry mouth (34%), dysphagia (23%), and ageusia (18%). The median time to onset of oral toxicity was 15 (range: 1 to 634) days, and the median time to resolution to baseline was 43 (1 to 530) days. Oral toxicity did not resolve to baseline in 65% of patients.
TALVEY® can cause weight loss. In the clinical trial, 62% of patients experienced weight loss, regardless of having an oral toxicity, including 29% of patients with Grade 2 (10% or greater) weight loss and 2.7% of patients with Grade 3 (20% or greater) weight loss. The median time to onset of Grade 2 or higher weight loss was 67 (range: 6 to 407) days, and the median time to resolution was 50 (range: 1 to 403) days. Weight loss did not resolve in 57% of patients who reported weight loss.
Monitor patients for signs and symptoms of oral toxicity. Counsel patients to seek medical attention should signs or symptoms of oral toxicity occur and provide supportive care as per current clinical practice, including consultation with a nutritionist. Monitor weight regularly during therapy. Evaluate clinically significant weight loss further. Withhold TALVEY® or permanently discontinue based on severity.
Infections: TALVEY® can cause infections, including life-threatening or fatal infections. Serious infections occurred in 16% of patients, with fatal infections in 1.5% of patients. Grade 3 or 4 infections occurred in 17% of patients. The most common serious infections reported were bacterial infection (8%), which included sepsis and COVID-19 (2.7%).
