Uses
1 INDICATIONS AND USAGE LYNOZYFIC 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) ] . Continued approval for this indication may be contingent upon verification and description of clinical benefit in confirmatory trial(s).

Side Effects
6 ADVERSE REACTIONS The following clinically significant adverse reactions are described elsewhere in the labeling: Cytokine Release Syndrome [see Warnings and Precautions (5.1) ] Neurologic Toxicity, including Immune Effector Cell-Associated Neurotoxicity Syndrome [see Warnings and Precautions (5.2) ] Infections [see Warnings and Precautions (5.4) ] Neutropenia [see Warnings and Precautions (5.5) ] Hepatotoxicity [see Warnings and Precautions (5.6) ] The most common adverse reactions (≥20%) are musculoskeletal pain, cytokine release syndrome, cough, upper respiratory tract infection, diarrhea, fatigue, pneumonia, nausea, headache, and dyspnea.
Interactions
7 DRUG INTERACTIONS 7.1 Effects of LYNOZYFIC on Other Drugs Certain CYP substrates Monitor for toxicity unless otherwise recommended in the Prescribing Information of certain CYP substrates where minimal changes in the concentration may lead to serious adverse reactions when used concomitantly with LYNOZYFIC. Linvoseltamab-gcpt causes the release of cytokines [see Clinical Pharmacology (12.2) ] that may suppress cytochrome P450 (CYP) enzyme activity . Concomitant use with LYNOZYFIC increases CYP substrate exposure which may increase the risk of adverse reactions related to these substrates.
Warnings
WARNING: CYTOKINE RELEASE SYNDROME AND NEUROLOGIC TOXICITY, INCLUDING IMMUNE EFFECTOR CELL-ASSOCIATED NEUROTOXICITY SYNDROME Cytokine release syndrome (CRS), including serious or life-threatening reactions, can occur in patients receiving LYNOZYFIC. Initiate treatment with LYNOZYFIC step-up dosing to reduce the risk of CRS. 5 WARNINGS AND PRECAUTIONS Infections : Can cause serious or fatal infections. Monitor patients for signs or symptoms of infection and treat accordingly. ( 5.4 ) Neutropenia : Monitor complete blood cell counts at baseline and periodically during treatment. ( 5.5 ) Hepatotoxicity: Can cause hepatotoxicity. Monitor liver enzymes and bilirubin at baseline and during treatment as clinically indicated. ( 5.6 ) Embryo-Fetal Toxicity: May cause fetal harm. Advise females of reproductive potential of the potential risk to the fetus and to use effective contraception. ( 5.7 , 8.1 , 8.3 ) 5.1 Cytokine Release Syndrome (CRS) LYNOZYFIC can cause cytokine release syndrome (CRS), which can be serious or life-threatening. 4 CONTRAINDICATIONS None. None. ( 4 )
Pregnancy
8.1 Pregnancy Risk Summary Based on the mechanism of action, LYNOZYFIC may cause fetal harm when administered to a pregnant woman [see Clinical Pharmacology (12.1) ] . There are no available data on the use of LYNOZYFIC in pregnant women to evaluate for a drug associated risk. No animal reproductive or developmental toxicity studies have been conducted with LYNOZYFIC. Linvoseltamab-gcpt causes T-cell activation and cytokine release; immune activation may compromise pregnancy maintenance.
Storage
Store unopened vial in a refrigerator at 2°C to 8°C (36°F to 46°F) in the original carton to protect from light. Do not freeze or shake.
