Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
Relapsed/Refractory Multiple Myeloma
In Combination with Daratumumab and Hyaluronidase-fihj
The safety of TECVAYLI in combination with daratumumab and hyaluronidase-fihj (N=283) compared with either daratumumab and hyaluronidase-fihj, pomalidomide and dexamethasone (DPd) or daratumumab and hyaluronidase-fihj, bortezomib and dexamethasone (DVd) (N=290) was evaluated in patients with relapsed or refractory multiple myeloma in MajesTEC-3 [see Clinical Studies (14.1)]. Patients received step-up doses of 0.06 mg/kg and 0.3 mg/kg of TECVAYLI followed by TECVAYLI 1.5 mg/kg once weekly, followed by TECVAYLI 3 mg/kg every two weeks, followed by TECVAYLI 3 mg/kg every four weeks, subcutaneously.
Among patients who received TECVAYLI in combination with daratumumab and hyaluronidase-fihj the median exposure was 32 (range 0.03 to 43) months. Among patients who received DPd or DVd the median exposure was 16 (range 0.03 to 45) months.
Serious adverse reactions occurred in 71% of patients who received TECVAYLI in combination with daratumumab and hyaluronidase-fihj. Serious adverse reactions reported in ≥3% of patients included pneumonia (33%), upper respiratory tract infection (15%), cytokine release syndrome (10%), COVID-19 (7%), sepsis (6%), second primary malignancy (5%), pyrexia (4.9%), febrile neutropenia (4.6%), and gastroenteritis (4.2%).
Fatal adverse reactions occurred in 2.5% of patients who received TECVAYLI in combination with daratumumab and hyaluronidase-fihj, and included sepsis (0.7%), pneumonia (0.4%), sudden death (0.4%), myocardial infarction (0.4%), enterovirus myocarditis (0.4%) and hemophagocytic lymphohistiocytosis (0.4%).
Permanent discontinuation of TECVAYLI due to adverse reactions occurred in 6% of patients. Adverse reactions leading to discontinuation of TECVAYLI in more than one patient were pneumonia (1.1%), diarrhea (0.7%), fatigue (0.7%), second primary malignancy (0.7%), upper respiratory tract infection (0.7%) and cough (0.7%).
Dosage interruptions of TECVAYLI due to an adverse reaction occurred in 94% of patients. Adverse reactions which required dosage interruption of TECVAYLI in ≥5% of patients included neutropenia (53%), upper respiratory tract infection (48%), COVID-19 (34%), pneumonia (34%), thrombocytopenia (14%), cytokine release syndrome (13%), gastroenteritis (10%), cough (10%), pyrexia (8%), diarrhea (7%), sepsis (6%) and fatigue (5%).
The most common adverse reactions (≥20%) were hypogammaglobulinemia, upper respiratory tract infection, cytokine release syndrome, cough, diarrhea, musculoskeletal pain, COVID-19, pneumonia, injection site reaction, fatigue, pyrexia, headache, nausea, gastroenteritis, and weight decreased.
The most common Grade 3 to 4 laboratory abnormalities (≥20%) were decreased lymphocytes, decreased neutrophils, decreased white blood cells and decreased platelets.

Monotherapy
The safety of TECVAYLI monotherapy (N=165) in patients with relapsed or refractory multiple myeloma was evaluated in MajesTEC-1 [see Clinical Studies (14.1)]. Patients received step-up doses of 0.06 mg/kg and 0.3 mg/kg of TECVAYLI followed by TECVAYLI 1.5 mg/kg, subcutaneously once weekly. Among patients who received TECVAYLI, 47% were exposed for 6 months or longer and 7% were exposed for one year or longer.
The median age of patients who received TECVAYLI was 64 years (range: 33 to 84 years); 58% were male; 81% were White, 13% were Black or African American, and 2% were Asian.
Serious adverse reactions occurred in 54% of patients who received TECVAYLI. Serious adverse reactions in >2% of patients included pneumonia (15%), cytokine release syndrome (8%), sepsis (6%), general physical health deterioration (6%), COVID-19 (6%), acute kidney injury (4.8%), pyrexia (4.8%), musculoskeletal pain (2.4%), and encephalopathy (2.4%).
Fatal adverse reactions occurred in 5% of patients who received TECVAYLI, including COVID-19 (1.8%), pneumonia (1.8%), septic shock (0.6%), acute renal failure (0.6%), and hemoperitoneum (0.6%).
Permanent discontinuation of TECVAYLI due to adverse reactions occurred in 1.2% of patients. Adverse reactions resulting in permanent discontinuation of TECVAYLI included pneumonia (adenoviral and pneumocystis jirovecii pneumonia in the same patient) and hypercalcemia.
Dosage interruptions of TECVAYLI due to an adverse reaction occurred in 73% of patients. Adverse reactions which required dosage interruption in >5% of patients included neutropenia, pneumonia, pyrexia, cytokine release syndrome, upper respiratory tract infection, and COVID-19.
The most common adverse reactions (≥20%) were pyrexia, CRS, musculoskeletal pain, injection site reaction, fatigue, upper respiratory tract infection, nausea, headache, pneumonia, and diarrhea. The most common Grade 3 to 4 laboratory abnormalities (≥20%) were decreased lymphocytes, decreased neutrophils, decreased white blood cells, decreased hemoglobin, and decreased platelets.
