Yahoo Finance TALVEY® (talquetamab-tgvs) demonstrates highly durable, longer-term responses in patients with relapsed or refractory multiple myeloma
24-month overall survival rate of 67 percent achieved with TALVEY® 0.8 mg/kg biweekly dosing in the Phase 1/2 MonumenTAL-1 study
MADRID, June 14, 2024 /PRNewswire/ -- Johnson & Johnson (NYSE: JNJ) announced today that long-term data from the Phase 1/2 MonumenTAL-1 study showed that with 20 to 30 months of median follow-up, triple-class-exposed patients with relapsed or refractory multiple myeloma (RRMM) who were treated with TALVEY® (talquetamab-tgvs) maintained high overall response rates (ORR) and durable responses, irrespective of whether they had received prior T-cell redirection therapy.1 These data, featured in a poster presentation at the 2024 European Hematology Association (EHA) Congress (Abstract #P915) demonstrate the efficacy and durability of TALVEY® when used before or after chimeric antigen receptor T-cell (CAR-T) therapy or bispecific antibody therapies in triple-class-exposed patients with RRMM.1
"Results from the MonumenTAL-1 study continue to show deeper response levels and a longer duration of response in patients treated with either of the approved dose options of talquetamab, while the median overall survival has yet to be reached at two years," said Dr. Leo Rasche, attending physician on the myeloma service, University Hospital of Würzburg.* "It is encouraging to see no notable increases in treatment-related discontinuations with this longer follow-up across cohorts."
In MonumenTAL-1, 297 patients with no prior exposure to T-cell redirection therapy received TALVEY® at the recommended Phase 2 dose (RP2D) of 0.8 mg/kg biweekly (Q2W) (n=154) or 0.4 mg/kg weekly (QW) (n=143).1 At a median follow-up of 23.4 months, patients in the Q2W cohort demonstrated a median duration of response (DOR) of 17.5 months, with median DOR not reached in patients with complete response (CR) or better. For patients in the QW arm, a median follow-up of 29.8 months showed a median DOR of 9.5 months with a median DOR of 28.6 months in patients with a CR or better. At 24 months, 67.1 percent and 60.6 percent of patients were alive from the two dosing cohorts, respectively.1
At a median follow-up of 20.5 months, TALVEY® continued to show strong efficacy in patients with prior T-cell redirection therapy exposure (n=78), with 55.1 percent of patients achieving very good partial response (VGPR) or better and 57.3 percent alive at 24.2 months.1
Infection rates remained lower than in studies of B-cell maturation antigen–targeted bispecific antibodies (BsAbs), consistent with previous reports. No increase in grade 3/4 infections was observed, with longer follow-up GPRC5D-associated adverse events (AEs) led to few dose reductions and discontinuations. One additional patient discontinued treatment due to AEs since the previous report. Weight loss, as assessed by vital signs, was evident early but stabilized and improved over time, including in patients with oral toxicities. 1
Data from MonumenTAL-2 support continued durable responses at one year with investigational combination of TALVEY® and pomalidomide in patients with RRMM who had ≥ two prior lines of therapy
Longer follow-up from the Phase 1b MonumenTAL-2 study of the investigational use of TALVEY® and pomalidomide show deep responses and a manageable safety profile in patients with RRMM and support the potential to combine TALVEY® with an immunomodulatory agent (IMiD). These updated data, from the first-ever study of a regimen combining a GPRC5D-targeted therapy and an immunomodulatory agent, were featured as a poster presentation at the 2024 EHA Congress (Abstract #P911).2
Patients in the Phase 1b MonumenTAL-2 study (n=35) were treated with subcutaneous (SC) TALVEY® at the RP2D of 0.8 mg/kg (Q2W) (n=19) or 0.4 mg/kg (QW) (n=16) with step-up doses, plus 2.0 mg of oral pomalidomide daily. At a median follow-up of 16.8 months (range, 1.2-25.1), response-evaluable patients demonstrated an ORR of 88.6 percent (≥ VGPR, 80 percent).2
"With multiple dosing options and the ability to be used both before or after CAR-T therapy and BCMA bispecifics, TALVEY is an important and versatile treatment option for the treatment of relapsed or refractory multiple myeloma," said Jordan Schecter, M.D., Vice President, Disease Area Leader, Multiple Myeloma, at Johnson & Johnson Innovative Medicine. "The low rate of grade 3/4 infections seen in MonumenTAL-2 suggests the flexibility of TALVEY as a combination partner with an immunomodulatory agent for patients who continue to face limited treatment options with this complex hematologic disease."
At 12 months, 80.4 percent of patients who achieved a CR or better maintained their response.2 The progression-free survival (PFS) rate at 12 months was 72.6 percent.2
The most common grade 3/4 hematologic AEs were neutropenia (57.1 percent), anemia (25.7 percent), and thrombocytopenia (20 percent).2 Taste, nail, skin, and rash toxicities occurred in 85.7 percent, 68.6 percent, 74.3 percent, and 28.6 percent of patients, respectively; the majority were grade 1/2 with few discontinuations.2 Cytokine release syndrome (CRS) occurred in 74.3 percent and infections occurred in 80 percent (22.9 percent, grade 3/4) of patients.2

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.8 In multiple myeloma, these plasma cells change, spread rapidly and replace normal cells in the bone marrow with tumors.9 Multiple myeloma is the third most common blood cancer and remains an incurable disease.10 In 2023, it is estimated that more than 35,000 people will be diagnosed with multiple myeloma in the U.S. and more than 12,000 people will die from the disease.11 People living with multiple myeloma have a five-year relative survival rate of 59.8 percent.12 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.13,14

IMPORTANT SAFETY INFORMATION
WARNING: CYTOKINE RELEASE SYNDROME and NEUROLOGIC TOXICITY, including IMMUNE EFFECTOR CELL-ASSOCIATED NEUROTOXICITY SYNDROME
Cytokine release syndrome (CRS), including life-threatening or fatal reactions, can occur in patients receiving TALVEY®. Initiate TALVEY® treatment with step-up dosing to reduce the risk of CRS. Withhold TALVEY® until CRS resolves or permanently discontinue based on severity.
Neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS), and serious and life-threatening or fatal reactions, can occur with TALVEY®. Monitor patients for signs and symptoms of neurologic toxicity including ICANS during treatment and treat promptly. Withhold or permanently discontinue TALVEY® based on severity.
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%. Most events occurred following step-up dose 1 (29%) or step-up dose 2 (44%) at the recommended dosages. Recurrent CRS occurred in 30% of patients. 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, including immune effector cell-associated neurotoxicity syndrome (ICANS), including fatal reactions. In the clinical trial, neurologic toxicity 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.
Further information about the TECVAYLI® and TALVEY® REMS program is available at www.TEC-TALREMS.com or by telephone at 1-855-810-8064.
Oral Toxicity and Weight Loss: TALVEY® can cause oral toxicities, including dysgeusia, dry mouth, dysphagia, and stomatitis. In the clinical trial, 80% of patients had oral toxicity, with Grade 3 occurring in 2.1% of patients who received the recommended dosages. 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 of 5% or greater, regardless of having an oral toxicity, including 28% 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%).
Monitor patients for signs and symptoms of infection prior to and during treatment with TALVEY® and treat appropriately. Administer prophylactic antimicrobials according to local guidelines. Withhold or consider permanently discontinuing TALVEY® as recommended, based on severity.
Cytopenias: TALVEY® can cause cytopenias, including neutropenia and thrombocytopenia. In the clinical trial, Grade 3 or 4 decreased neutrophils occurred in 35% of patients, and Grade 3 or 4 decreased platelets occurred in 22% of patients who received TALVEY®. The median time to onset for Grade 3 or 4 neutropenia was 22 (range: 1 to 312) days, and the median time to resolution to Grade 2 or lower was 8 (range: 1 to 79) days. The median time to onset for Grade 3 or 4 thrombocytopenia was 12 (range: 2 to 183) days, and the median time to resolution to Grade 2 or lower was 10 (range: 1 to 64) days. Monitor complete blood counts during treatment and withhold TALVEY® as recommended, based on severity.
Skin Toxicity: TALVEY® can cause serious skin reactions, including rash, maculo-papular rash, erythema, and erythematous rash. In the clinical trial, skin reactions occurred in 62% of patients, with grade 3 skin reactions in 0.3%. The median time to onset was 25 (range: 1 to 630) days. The median time to improvement to grade 1 or less was 33 days.
Monitor for skin toxicity, including rash progression. Consider early intervention and treatment to manage skin toxicity. Withhold TALVEY® as recommended based on severity.
Hepatotoxicity: TALVEY® can cause hepatotoxicity. Elevated ALT occurred in 33% of patients, with grade 3 or 4 ALT elevation occurring in 2.7%; elevated AST occurred in 31% of patients, with grade 3 or 4 AST elevation occurring in 3.3%. Grade 3 or 4 elevations of total bilirubin occurred in 0.3% of patients. Liver enzyme elevation can occur with or without concurrent CRS.
Monitor liver enzymes and bilirubin at baseline and during treatment as clinically indicated. Withhold TALVEY® or consider permanent discontinuation of TALVEY®, based on severity [see Dosage and Administration (2.5)].
