  • 5 WARNINGS AND PRECAUTIONS

    5.1 Cytokine Release Syndrome

    TECVAYLI can cause cytokine release syndrome (CRS), including life-threatening or fatal reactions [see Adverse Reactions (6.1)].

    In the clinical trials (monotherapy and combination therapy trials; N=448), CRS occurred in 64% of patients who received TECVAYLI at the recommended dosage, with Grade 1 CRS occurring in 46% of patients, Grade 2 in 18%, and Grade 3 in 0.2%. Recurrent CRS occurred in 27% of patients. Most patients experienced CRS during the initial step-up dosing schedule (step-up dose 1 (37%), step-up dose 2 (32%), or the initial treatment dose (20%)). CRS first occurred following subsequent doses of TECVAYLI in 2.5% of patients. The median time to onset of CRS was 2 (range: 1 to 9) days after the most recent dose and the median duration of CRS was 2 (range: 1 to 22) days.

    Clinical signs and symptoms of CRS included, but were not limited to, fever, hypoxia, chills, hypotension, sinus tachycardia, headache, and elevated liver enzymes (aspartate aminotransferase and alanine aminotransferase elevation).

    Initiate therapy according to TECVAYLI step-up dosing schedule to reduce risk of CRS [see Dosage and Administration (2.1, 2.5)]. Administer pretreatment medications to reduce risk of CRS and monitor patients following administration of TECVAYLI accordingly [see Dosage and Administration (2.3, 2.5)].

    At the first sign of CRS, immediately evaluate the patient for hospitalization. Administer supportive care based on severity and consider further management per current practice guidelines. Withhold until CRS resolves or permanently discontinue TECVAYLI based on severity [see Dosage and Administration (2.5)].

    TECVAYLI is available only through a restricted program under a REMS [see Warnings and Precautions (5.3)].

    5.2 Neurologic Toxicity including Immune Effector Cell-Associated Neurotoxicity Syndrome

    TECVAYLI can cause serious, life-threatening or fatal neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS) [see Adverse Reactions (6.1)].

    In the clinical trials (monotherapy and combination therapy trials; N=448), neurologic toxicity occurred in 60% of patients who received TECVAYLI at the recommended dosage, with Grade 3 or 4 neurologic toxicity in 6%. Neurologic toxicities reported in ≥5% of patients included headache (27%), sensory neuropathy (16%), motor dysfunction (15%), insomnia (12%), encephalopathy (11%), and dizziness (8%). Fatal neurologic toxicity occurred in 0.4% of patients, including Guillain-Barré syndrome and status epilepticus (one patient each).

    In MajesTEC-1, ICANS was reported in 6% of patients who received TECVAYLI as monotherapy at the recommended dosage [see Adverse Reactions (6.1)]. Recurrent ICANS occurred in 1.8% of patients. Most patients experienced ICANS following step-up dose 1 (1.2%), step-up dose 2 (0.6%), or the initial treatment dose (1.8%). Less than 3% of patients developed first occurrence of ICANS following subsequent TECVAYLI doses. The median time to onset of ICANS was 4 days (range: 2 to 8 days) after the most recent TECVAYLI dose with a median duration of 3 days (range: 1 to 20 days). The most frequent clinical manifestations of ICANS reported were confusional state and dysgraphia.

    In MajesTEC-3, ICANS was reported in 1.1% of patients who received the recommended TECVAYLI dosage in combination with daratumumab and hyaluronidase-fihj, including Grade 4 ICANS in 1 patient. All events of ICANS occurred during the step-up dosing schedule [see Adverse Reactions (6.1)]. The median time to onset of ICANS was 2 days (range: 1 to 3 days) after the most recent dose and the median duration of ICANS was 2 days (range: 1 to 2 days). The clinical manifestations of ICANS reported were amnesia, encephalopathy and delirium.

    The onset of ICANS can be concurrent with CRS, following resolution of CRS, or in the absence of CRS.

    Monitor patients for signs and symptoms of neurologic toxicity, including ICANS during TECVAYLI treatment. At the first sign of neurologic toxicity, including ICANS, immediately evaluate patient and provide supportive therapy based on severity. Withhold until neurologic toxicity resolves or permanently discontinue TECVAYLI based on severity per recommendations and consider further management per current practice guidelines [see Dosage and Administration (2.5)].

    Due to the potential for neurologic toxicity, patients receiving TECVAYLI are at risk of depressed level of consciousness [see Adverse Reactions (6.1)]. Advise patients to refrain from driving or operating heavy or potentially dangerous machinery during and for 48 hours after completion of TECVAYLI step-up dosing schedule and in the event of new onset of any neurologic toxicity symptoms until neurologic toxicity resolves [see Dosage and Administration (2.1)].

    TECVAYLI is available only through a restricted program under a REMS [see Warnings and Precautions (5.3)].

    5.3 TECVAYLI and TALVEY REMS

    TECVAYLI 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 [see Warnings and Precautions (5.1, 5.2)].

    Notable requirements of the TECVAYLI and TALVEY REMS include the following:

    • Prescribers must be certified with the REMS by enrolling and completing training.
    • Prescribers must counsel patients receiving TECVAYLI about the risk of CRS and neurologic toxicity, including ICANS, and provide patients with Patient Wallet Card.
    • Pharmacies and healthcare settings that dispense TECVAYLI must be certified with this REMS and must verify prescribers are certified through this REMS.
    • Wholesalers and distributers must only distribute TECVAYLI to certified pharmacies or healthcare settings.

    Further information about the "TECVAYLI and TALVEY REMS" is available at www.TEC-TALREMS.com or by telephone at 1-855-810-8064.

    5.4 Hepatotoxicity

    TECVAYLI can cause hepatotoxicity, including fatalities. There was one fatal case of hepatic failure in MajesTEC-1. In patients who received TECVAYLI at the recommended dosage in the clinical trials (monotherapy and combination therapy trials; N=448), elevated aspartate aminotransferase (AST) occurred in 47% of patients, with Grade 3 or 4 elevations in 2.9%. Elevated alanine aminotransferase (ALT) occurred in 48% of patients, with Grade 3 or 4 elevations in 3.8%. Elevated total bilirubin occurred in 10% of patients with Grade 3 or 4 elevations in 0.7%. Liver enzyme elevation can occur with or without concurrent CRS.

    Monitor liver enzymes and bilirubin at baseline and during TECVAYLI treatment as clinically indicated. Withhold TECVAYLI or consider permanent discontinuation of TECVAYLI based on severity [see Dosage and Administration (2.5)].

    5.5 Infections

    TECVAYLI can cause severe, life-threatening, or fatal infections.

    In MajesTEC-1 (N=165), in patients who received the recommended TECVAYLI dosage, serious infections, including opportunistic infections, occurred in 30% of patients, Grade 3 or 4 infections occurred in 35% of patients, and fatal infections occurred in 4.2% of patients [see Adverse Reactions (6.1)].

    In MajesTEC-3 (N=283), in patients who received TECVAYLI in combination with daratumumab and hyaluronidase-fihj at the recommended dosage, serious infections, including opportunistic infections, occurred in 54% of patients, Grade 3 or Grade 4 infections occurred in 54% of patients and fatal infections occurred in 4.6% of patients [see Adverse Reactions (6.1)].

    Monitor patients for signs and symptoms of infection prior to and during treatment with TECVAYLI and treat appropriately. Administer prophylactic antimicrobials according to current practice guidelines [see Dosage and Administration (2.3)].

    Withhold TECVAYLI or consider permanent discontinuation of TECVAYLI based on severity [see Dosage and Administration (2.5)].

    Monitor immunoglobulin levels prior to and during treatment with TECVAYLI and administer subcutaneous or intravenous immunoglobulin (IVIG) to maintain the serum levels >400 mg/dL.

    5.6 Neutropenia

    TECVAYLI can cause neutropenia and febrile neutropenia. In patients who received TECVAYLI at the recommended dosage in the clinical trials (monotherapy and combination therapy trials; N=448), decreased neutrophils occurred in 88% of patients, with Grade 3 or 4 decreased neutrophils in 70%. Febrile neutropenia occurred in 6% of patients [see Adverse Reactions (6.1)].

    Monitor complete blood cell counts at baseline and periodically during treatment and provide supportive care per local institutional guidelines.

    Monitor patients with neutropenia for signs of infection.

    Withhold TECVAYLI based on severity [see Dosage and Administration (2.5)].

    5.7 Hypersensitivity and Other Administration Reactions

    TECVAYLI can cause both systemic administration-related reactions and local injection-site reactions.

    Systemic Reactions

    In patients who received the recommended TECVAYLI dosage in the clinical trials (monotherapy and combination therapy trials; N=448), 2.5% of patients experienced systemic-administration reactions, which included recurrent pyrexia and rash.

    Local Reactions

    In patients who received TECVAYLI at the recommended dosage in the clinical trials (monotherapy and combination therapy trials; N=448), injection-site reactions occurred in 37% of patients with Grade 1 injection-site reactions in 29% and Grade 2 in 9%.

    Withhold TECVAYLI or consider permanent discontinuation of TECVAYLI based on severity [see Dosage and Administration (2.5)].

    5.8 Embryo-Fetal Toxicity

    Based on its mechanism of action, TECVAYLI may cause fetal harm when administered to a pregnant patient. Advise pregnant patients of the potential risk to the fetus. Advise females of reproductive potential to use effective contraception during treatment with TECVAYLI and for 5 months after the last dose [see Use in Specific Populations (8.1, 8.3)].

  • 6 ADVERSE REACTIONS

    The following adverse reactions are also described elsewhere in the labeling:

    6.1 Clinical Trials Experience

    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

  • 7 DRUG INTERACTIONS

    TECVAYLI causes release of cytokines [see Clinical Pharmacology (12.2)] that may suppress activity of certain cytochrome P450 (CYP) enzymes, resulting in increased exposure of CYP substrates, which may increase the risk of adverse reactions of the CYP substrates. The highest risk of drug-drug interaction is expected to occur after initiation of TECVAYLI step-up dosing schedule up to 7 days after the first treatment dose and during and after CRS [see Warnings and Precautions (5.1)].

    Monitor for toxicity and/or concentrations of CYP substrates where minimal increases in concentration may lead to serious adverse reactions. Consider decreasing the dosage of the concomitant CYP substrate as needed.

  • 8 USE IN SPECIFIC POPULATIONS

    8.1 Pregnancy

    Risk Summary

    Based on the mechanism of action, TECVAYLI may cause fetal harm when administered to a pregnant patient [see Clinical Pharmacology (12.1)]. There are no available data on the use of TECVAYLI in pregnant patients to evaluate for a drug associated risk. No animal reproductive or developmental toxicity studies have been conducted with TECVAYLI. Teclistamab-cqyv causes T-cell activation and cytokine release; immune activation may compromise pregnancy maintenance. Human immunoglobulin G (IgG) is known to cross the placenta; therefore, teclistamab-cqyv has the potential to be transmitted from the mother to the developing fetus. Advise women of the potential risk to the fetus.

    TECVAYLI is associated with hypogammaglobulinemia, therefore, assessment of immunoglobulin levels in newborns of mothers treated with TECVAYLI should be considered.

    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 are no data on the presence of teclistamab-cqyv in human milk, the effect on the breastfed child, or the effects 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 TECVAYLI are unknown. Because of the potential for serious adverse reactions in a breastfed child, advise women not to breastfeed during treatment with TECVAYLI and for 5 months after the last dose.

    8.3 Females and Males of Reproductive Potential

    TECVAYLI may cause fetal harm when administered to a pregnant patient [see Use in Specific Populations (8.1)].

    Pregnancy Testing

    Verify pregnancy status of females of reproductive potential prior to initiating TECVAYLI.

    Contraception

    Females

    Advise females of reproductive potential to use effective contraception during treatment and for 5 months after the last dose of TECVAYLI.

    8.4 Pediatric Use

    The safety and efficacy of TECVAYLI have not been established in pediatric patients.

    8.5 Geriatric Use

    • Of the 165 patients with relapsed or refractory multiple myeloma treated with TECVAYLI in MajesTEC-1 at the recommended dosage, 48% were 65 years of age or older, and 15% were 75 years of age or older. No overall differences in safety or effectiveness were observed between patients 65 to 74 years of age compared to younger patients. The study did not include a sufficient number of patients 75 years of age or older to assess whether there are differences in safety or effectiveness.
    • Of the 291 patients with relapsed or refractory multiple myeloma treated with TECVAYLI at the recommended dosage in combination with daratumumab and hyaluronidase-fihj in MajesTEC-3, 51% were younger than 65 years of age, 39% were 65 to 74 years of age, and 11% were 75 years of age or older. No overall differences in effectiveness were observed between patients 65 to 74 years of age compared to younger patients. The study did not include a sufficient number of patients 75 years of age or older to assess whether there are differences in effectiveness compared to younger patients. There was a higher incidence of serious adverse reactions in patients 75 years of age or older (83%) and in patients 65 to 74 years of age (77%) as compared to patients younger than 65 years of age (63%).
  • 11 DESCRIPTION

    Teclistamab-cqyv, a bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager, is a humanized immunoglobulin G4-proline, alanine, alanine (IgG4-PAA) antibody. Teclistamab-cqyv is produced in Chinese Hamster Ovary (CHO) cells using recombinant DNA technology. Teclistamab-cqyv consists of an anti-BCMA heavy chain and light chain and an anti-CD3 heavy chain and light chain with two interchain disulfide bonds connecting the two arms. The molecular weight of teclistamab-cqyv is approximately 146 kDa.

    TECVAYLI® (teclistamab-cqyv) injection is a sterile, preservative-free, clear to slightly opalescent, colorless to light yellow solution supplied in a single-dose vial for subcutaneous administration.

    Each TECVAYLI 3 mL single-dose vial contains 30 mg of teclistamab-cqyv, edetate disodium (0.054 mg), glacial acetic acid (0.72 mg), polysorbate 20 (1.2 mg), sodium acetate (2.7 mg), sucrose (240 mg), and Water for Injection, USP.

    Each TECVAYLI 1.7 mL single-dose vial contains 153 mg of teclistamab-cqyv, edetate disodium (0.031 mg), glacial acetic acid (0.41 mg), polysorbate 20 (0.68 mg), sodium acetate (1.5 mg), sucrose (140 mg), and Water for Injection, USP.

  • 12 CLINICAL PHARMACOLOGY

    12.1 Mechanism of Action

    Teclistamab-cqyv is a bispecific T-cell engaging antibody that binds to the CD3 receptor expressed on the surface of T-cells and B-cell maturation antigen (BCMA) expressed on the surface of multiple myeloma cells and some healthy B-lineage cells.

    In vitro, teclistamab-cqyv activated T-cells, caused the release of various proinflammatory cytokines, and resulted in the lysis of multiple myeloma cells.

    12.2 Pharmacodynamics

    Serum concentrations of cytokines (IL-6, IL-10, TNF-α, and IFN-γ) and IL-2R were measured before and after administration of step-up dose 1, step-up dose 2, and the three weekly doses of 1.5 mg/kg of TECVAYLI. Increased concentrations of IL-6, IL-10, and IL-2R were observed during this period.

    12.3 Pharmacokinetics

    The Cmax and Cavg of teclistamab-cqyv after the first subcutaneous 1.5 mg/kg TECVAYLI dose increase proportionally over a dosage range of 0.08 mg/kg to 3 mg/kg in monotherapy (0.05 to 2 times the approved recommended treatment dosage). Following the recommended dosage of TECVAYLI monotherapy, 90% of steady state exposure was achieved after 12 weekly TECVAYLI doses (1.5 mg/kg once weekly). The mean accumulation ratio between the first and 13th weekly dose of TECVAYLI 1.5 mg/kg was 4.2-fold for Cmax, 4.1-fold for Ctrough, and 5.3-fold for Cavg.

    The pharmacokinetic characteristics of teclistamab-cqyv were consistent whether used as monotherapy or in combination with daratumumab and hyaluronidase-fihj. The Cmax, Ctrough, and Cavg of teclistamab-cqyv are presented in Table 16.

    Absorption

    The mean bioavailability of teclistamab-cqyv was 72% after subcutaneous administration of TECVAYLI. The median (range) Tmax of teclistamab-cqyv after the first and 13th TECVAYLI monotherapy treatment doses were 139 (19 to 168) hours and 72 (24 to 168) hours, respectively.

    Distribution

    The mean (coefficient of variation [CV]%) volume of distribution of teclistamab-cqyv was 5.63 L (29%).

    Elimination

    Teclistamab-cqyv clearance decreases over time, with a mean (CV%) maximal reduction from baseline to the 13th weekly TECVAYLI monotherapy treatment dose of 40.8% (56%). The geometric mean (CV%) clearance is 0.472 L/day (64%) at the 13th weekly TECVAYLI monotherapy treatment dose. Patients who discontinue TECVAYLI after the 13th weekly monotherapy treatment dose are expected to have a 50% reduction from Cmax in teclistamab-cqyv concentration at a median (5th to 95th percentile) time of 15 days (7 to 33 days) after Tmax and a 97% reduction from Cmax in teclistamab-cqyv concentration at a median time of 69 days (32 to 163 days) after Tmax.

    Specific Populations

    There were no clinically significant differences in the exposure of teclistamab-cqyv based on age (24 to 84 years), sex, race (White, Black or African American), ethnicity (Hispanic/Latino, not Hispanic/Latino), mild or moderate renal impairment (estimated glomerular filtration rate [eGFR] by Modification of Diet in Renal Disease [MDRD] method: 30 to 89 mL/minute), or mild hepatic impairment (total bilirubin less than or equal to upper limit of normal [ULN] with AST greater than ULN or total bilirubin greater than 1 to 1.5 times ULN with any AST). The effects of severe renal impairment (eGFR less than 30 mL/minute) or moderate to severe hepatic impairment (total bilirubin greater than 1.5 times ULN with any AST) on the exposures of teclistamab-cqyv are unknown.

    Body Weight

    The volume of distribution and clearance of teclistamab-cqyv increase with increasing body weight (37.6 kg to 164 kg), supporting a weight-based dose.

    Drug Interaction Studies

    No clinical studies evaluating the drug interaction potential of teclistamab-cqyv have been conducted.

    12.6 Immunogenicity

    The observed incidence of anti-drug antibodies is highly dependent on the sensitivity and specificity of the assay. Differences in assay methods preclude meaningful comparisons of the incidence of anti-drug antibodies in the studies described below with the incidence of anti-drug antibodies in other studies, including those of teclistamab-cqyv or of other teclistamab products.

    Among patients treated with subcutaneous TECVAYLI at various dosages, anti-teclistamab-cqyv antibodies developed in 1/186 (0.5%) of patients who received monotherapy (up to 27 months) and in 2/379 (0.5%) of patients who received combination therapy with daratumumab and hyaluronidase-fihj (up to 43 months). Because of the low occurrence of anti-teclistamab-cqyv antibodies, the effect of these antibodies on the pharmacokinetics, pharmacodynamics, safety, and/or effectiveness of teclistamab products is unknown.

    14.1 Relapsed or Refractory Multiple Myeloma

    In Combination with Daratumumab and Hyaluronidase-fihj

    The efficacy of TECVAYLI in combination with subcutaneous daratumumab and hyaluronidase-fihj compared with investigator's choice of either daratumumab and hyaluronidase-fihj, pomalidomide and dexamethasone (DPd) or daratumumab and hyaluronidase-fihj, bortezomib and dexamethasone (DVd) was evaluated in adult patients with relapsed or refractory multiple myeloma in a randomized, open-label, multi-center study (MajesTEC-3) (NCT05083169). The study included patients who had previously received one to three prior lines of therapy including a proteasome inhibitor and lenalidomide. Patients who had received only one prior line of therapy must have been refractory to lenalidomide. Patients who had disease refractory to a prior anti-CD38 monoclonal antibody therapy, or who had received any prior BCMA-directed therapy were excluded.

    Patients received TECVAYLI in combination with daratumumab and hyaluronidase-fihj as follows:

    • Subcutaneous TECVAYLI step-up doses of 0.06 mg/kg and 0.3 mg/kg, followed by TECVAYLI 1.5 mg/kg once weekly from Weeks 2 to 8, then 3 mg/kg every two weeks from Weeks 9 to 24, then 3 mg/kg every four weeks starting on Week 25 until disease progression or unacceptable toxicity,
      AND
    • Subcutaneous daratumumab and hyaluronidase-fihj 1,800 mg/30,000 units (1,800 mg of daratumumab and 30,000 units of hyaluronidase) starting one day prior to TECVAYLI and continuing once weekly from Weeks 1 to 8, then every two weeks from Weeks 9 to 24, then every four weeks starting on Week 25 until disease progression or unacceptable toxicity [see Dosage and Administration (2.2)].

    The major efficacy outcome measure was progression-free survival (PFS) by Independent Review Committee (IRC) assessment based on International Myeloma Working Group (IMWG) 2016 criteria.

    A total of 587 patients were randomized in MajesTEC-3: 291 to the TECVAYLI in combination with daratumumab and hyaluronidase-fihj group and 296 to the control group (DPd or DVd). The median age was 64 years (range: 25 to 88) with 38% aged 65 to 74 years and 10% aged 75 years or older; 55% were male; 65% were White, 6% were Black or African American, and 22% were Asian. The International Staging System (ISS) at screening was stage I in 63%, stage II in 29%, and stage III in 8%. High-risk cytogenetics (presence of del(17p), t(4;14) or t(14;16)) were present in 35% of patients. Extramedullary disease was present in 5% of patients.

    The median number of prior lines of therapy was 2 (range: 1 to 3), with 38% who received one prior line of therapy. All patients received prior lenalidomide and 99.8% received a prior proteasome inhibitor; 84% were refractory to lenalidomide. Seventy-four percent of patients previously received autologous stem cell transplantation. Five percent of patients received a prior anti-CD38 monoclonal antibody; there is limited data with TECVAYLI in combination with daratumumab and hyaluronidase-fihj in patients who have received or are refractory to prior anti-CD38 monoclonal antibody therapy.

    The trial demonstrated a statistically significant improvement in the TECVAYLI in combination with daratumumab and hyaluronidase-fihj group compared with the control group in PFS and overall survival (OS). The efficacy results are shown in Table 17 and Figures 1 and 2.

    Monotherapy

    The efficacy of TECVAYLI was evaluated in patients with relapsed or refractory multiple myeloma in a single-arm, open-label, multi-center study (MajesTEC-1, NCT03145181 [Phase 1] and NCT04557098 [Phase 2]). The study included patients who had previously received at least three prior therapies, including a proteasome inhibitor, an immunomodulatory agent, and an anti-CD38 monoclonal antibody. The study excluded patients who had stroke, seizure, allogeneic stem cell transplantation within the past 6 months, Eastern Cooperative Oncology Group (ECOG) performance score of 2 or higher, known active CNS involvement or clinical signs of meningeal involvement of multiple myeloma, or active or documented history of autoimmune disease, with the exception of vitiligo, Type 1 diabetes, and prior autoimmune thyroiditis.

    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 thereafter until disease progression or unacceptable toxicity [see Dosage and Administration (2.2)].

    The efficacy population included 110 patients. The median age was 66 (range: 33 to 82) years with 16% of patients 75 years of age or older; 56% were male; 91% were White, 5% were Black or African American, 3% were Asian. The International Staging System (ISS) at study entry was Stage I in 50%, Stage II in 38%, and Stage III in 12% of patients. High-risk cytogenetics (presence of del(17p), t(4;14) or t(14;16)) were present in 25% of patients. Seventeen percent of patients had extramedullary plasmacytomas. Patients with prior BCMA-targeted therapy were not included in the efficacy population.

    The median number of prior lines of therapy was 5 (range: 2 to 14); 78% of patients had received at least 4 prior lines of therapy. Eighty-one percent of patients received prior stem cell transplantation. All patients had received prior therapy with a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 monoclonal antibody, and 76% were triple-class refractory (refractory to a proteasome inhibitor, an immunomodulatory agent and an anti-CD38 monoclonal antibody).

    Efficacy was established based on overall response rate (ORR) as determined by the Independent Review Committee (IRC) assessment using International Myeloma Working Group (IMWG) 2016 criteria (see Table 18).

    The median time to first response was 1.2 months (range: 0.2 to 5.5 months). With a median follow-up of 7.4 months among responders, the estimated duration of response (DOR) rate was 90.6% (95% CI: 80.3%, 95.7%) at 6 months and 66.5% (95% CI: 38.8%, 83.9%) at 9 months.

    Due to the risk of CRS, you will receive TECVAYLI on a "step-up dosing" schedule. You should be hospitalized for 48 hours after the first and second step-up doses and should stay close to a healthcare facility and be monitored by a healthcare provider for 48 hours after you receive your first treatment dose.
    • During the step-up dosing schedule your TECVAYLI dose will be increased for the first 3 doses. You will receive:
      • a smaller step-up dose as your first dose on day 1 of treatment
      • an increased step-up dose as your second dose, usually around day 3 or 4 of treatment
      • an increased dose as your first treatment dose, usually around day 7 of treatment
    • Your healthcare provider will decide the number of days to wait between your doses of TECVAYLI and how many treatments you will receive.
    • If your dose of TECVAYLI is delayed for any reason, you may need to repeat the step-up dosing schedule.
    • Before each step-up dose and your first treatment dose of TECVAYLI you will receive medicines to help reduce your risk of CRS. Your healthcare provider will decide if you need to receive medicines with future doses.
    • Neurologic problems. Tell your healthcare provider or get medical help right away if you develop any signs and symptoms of neurologic problems, including:
    • headache
    • jerking movements
    • rigid muscles
    • feeling restless
    • numbness and tingling (feeling like "pins and needles")
    • feeling less alert
    • feeling disorientated, confused, or seeing or hearing things that are not real (hallucinations)

    • changes in your handwriting
    • problems walking
    • muscle weakness in your body or face
    • burning, throbbing, or stabbing pain
    • feeling sleepy
    • memory problems
    Your healthcare provider will monitor you for signs and symptoms of CRS and neurologic problems during treatment with TECVAYLI and treat you as needed. Your healthcare provider may temporarily stop or completely stop your treatment with TECVAYLI if you develop CRS or neurologic problems.
    • TECVAYLI is available only through the TECVAYLI and TALVEY Risk Evaluation and Mitigation Strategy (REMS) due to the risk of CRS and neurologic problems.
