Boxed 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 [see Dosage and Administration (2.2 , 2.5 ) , Warnings and Precautions (5.1) ] . 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 [see Dosage and Administration (2.5) , Warnings and Precautions (5.2) ] . 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) [see Warnings and Precautions (5.3) ] . WARNING: CYTOKINE RELEASE SYNDROME and NEUROLOGIC TOXICITY, including IMMUNE EFFECTOR CELL-ASSOCIATED NEUROTOXICITY SYNDROME See full prescribing information for complete boxed warning.

Mechanism of action

Sourced from openFDA

Talquetamab-tgvs 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) expressed on the surface of multiple myeloma cells and non-malignant plasma cells, as well as healthy tissues such as epithelial cells in keratinized tissues of the skin and tongue. In vitro, talquetamab-tgvs activated T-cells caused the release of proinflammatory cytokines and resulted in the lysis of multiple myeloma cells.

Indications

Sourced from openFDA
  • TALVEY is indicated 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 monoclonal antibody. This indication is approved under accelerated approval based on response rate and durability of response [see Clinical Studies (14) ].ICD-10: C90.00

Oral Toxicity and Weight Loss : Monitor for oral toxicity and weight loss. Withhold or permanently discontinue based on severity. ( 5.4 ) Infections : Can cause serious, life-threatening, or fatal infections. Monitor for signs and symptoms of infection; treat appropriately. Withhold or consider permanent discontinuation based on severity. ( 5.5 ) Cytopenias : Monitor complete blood counts. ( 5.6 ) Skin Toxicity : Monitor for skin toxicity, including rash progression, for early intervention and treat appropriately. Withhold as recommended based on severity.

( 5.8 ) Embryo-Fetal Toxicity : May cause fetal harm. Advise females of reproductive potential of the potential risk to the fetus and to use effective contraception. ( 5.9 , 8.1 , 8.3 ) 5.1 Cytokine Release Syndrome (CRS) TALVEY can cause cytokine release syndrome, including life-threatening or fatal reactions [see Adverse Reactions (6.1) ] . 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).

Relapsed/Refractory Multiple Myeloma MonumenTAL-1 The safety of TALVEY was evaluated in 339 adult patients with relapsed or refractory multiple myeloma.

Use in specific populations

Sourced from openFDA

Lactation : Advise not to breastfeed. ( 8.2 ) 8.1 Pregnancy Risk Summary Based on the mechanism of action, TALVEY may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data on the use of TALVEY in pregnant women to evaluate for a drug associated risk. No animal reproductive or developmental toxicity studies have been conducted with talquetamab-tgvs. Talquetamab-tgvs causes T-cell activation and cytokine release; immune activation may compromise pregnancy maintenance. Human immunoglobulin G (IgG) is known to cross the placenta; therefore, TALVEY has the potential to be transmitted from the mother to the developing fetus. Advise women of the potential risk to the fetus. In the U.S. general population, the estimated background risk of major birth defects and miscarriage in clinically recognized pregnancies is 2% to 4% and 15% to 20%, respectively. 8.2 Lactation Risk Summary There is no information regarding the presence of talquetamab-tgvs in human milk, the effect on the breastfed child, or the effect on milk production. Maternal IgG is known to be present in human milk. The effects of local gastrointestinal exposure and limited systemic exposure in the breastfed child to TALVEY are unknown.

Pharmacokinetics

Sourced from openFDA
Metabolism
The C max and AUC tau of talquetamab-tgvs after subcutaneous administration increased proportionally over a dose range of 0.005 to 0.8 mg/kg weekly (0.01 to 2 times the recommended 0.4 mg/kg weekly treatment dose) and 0.8 to 1.2 mg/kg every two weeks (1 to 1.5 times the recommended 0.8 mg/kg every 2 weeks treatment dose). Ninety percent of steady state exposure was achieved 16 weeks after the first treatment dose for both regimens.
