ALERT: US Boxed Warning
Cytokine release syndrome:

Cytokine release syndrome (CRS), including life-threatening or fatal reactions, can occur in patients receiving teclistamab. Initiate treatment with teclistamab step-up dosing schedule to reduce risk of CRS. Withhold teclistamab until CRS resolves or permanently discontinue based on severity.

Neurologic toxicity including immune effector cell-associated neurotoxicity syndrome:

Neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS) and serious and life-threatening reactions, can occur with teclistamab. Monitor patients for signs or symptoms of neurologic toxicity, including ICANS, during treatment. Withhold teclistamab until neurologic toxicity resolves or permanently discontinue based on severity.

Risk Evaluation and Mitigation Strategy Program:

Because of the risk of CRS and neurologic toxicity, including ICANS, teclistamab is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the TECVAYLI REMS.

Brand Names: US
  • Tecvayli
Pharmacologic Category
  • Antineoplastic Agent, Anti-BCMA;
  • Antineoplastic Agent, Anti-CD3;
  • Antineoplastic Agent, Bispecific T Cell Engager;
  • Antineoplastic Agent, Monoclonal Antibody
Dosing: Adult

Note: Due to the risk of cytokine release syndrome (CRS) and neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS), patients should be hospitalized for 48 hours after all doses within the teclistamab step-up dosing schedule (step-up doses 1 and 2, as well as the first treatment dose).

Premedication: Premedicate 1 to 3 hours prior to teclistamab step-up dose 1, step-up dose 2, and the first treatment dose to reduce the risk and severity of CRS. Premedication may be necessary prior to subsequent doses in patients who repeat doses within the teclistamab step-up dosing schedule (following a dose delay), or who experienced CRS following the prior teclistamab dose.

Premedication should include a corticosteroid (IV or oral dexamethasone 16 mg), a histamine H1 antagonist (IV or oral diphenhydramine 50 mg or equivalent), and antipyretics (oral or IV acetaminophen 650 to 1,000 mg or equivalent).

Prophylaxis: Administer prophylactic antimicrobials according to clinical practice guidelines. Consider antiviral prophylaxis prior to teclistamab initiation to prevent herpes zoster reaction, per clinical guidelines.

Multiple myeloma, relapsed or refractory

Multiple myeloma, relapsed or refractory:

Day 1 (step-up dose 1): SUBQ: 0.06 mg/kg once.

Day 4 (step-up dose 2): SUBQ: 0.3 mg/kg once. Note: Step-up dose 2 may be administered 2 to 4 days after step-up dose 1 and, if necessary, up to 7 days after step-up dose 1 to allow for resolution of adverse reactions.

Day 7 (first treatment dose): SUBQ: 1.5 mg/kg once. Note: The first treatment dose may be administered 2 to 4 days after step-up dose 2 and, if necessary, up to 7 days after step-up dose 2 to allow for resolution of adverse reactions.

Warnings/Precautions

Concerns related to adverse effects:

• Cytokine release syndrome: Cytokine release syndrome (CRS), including fatal or life-threatening reactions, may occur; recurrent CRS has also been reported in approximately one-third of patients. Most patients experienced CRS following step-up dose 1, step-up dose 2, or the initial treatment dose. Only a small percentage of patients experienced first occurrence of CRS with subsequent teclistamab doses. The median time to onset of CRS was 2 days (range: 1 to 6 days) after the most recent dose and the median duration was 2 days (range: 1 to 9 days). Common manifestations of CRS included (but were not limited to) fever, hypoxia, chills, hypotension, sinus tachycardia, headache, and elevated liver enzymes. Patients should seek immediate medical attention if signs/symptoms of CRS occur at any time.

• Cytopenias: Teclistamab may cause neutropenia and febrile neutropenia. Neutropenia was reported in the majority of patients, with grade 3 or 4 neutropenia in over 50% of patients; febrile neutropenia occurred in some patients.

• Hepatotoxicity: Hepatotoxicity may occur with teclistamab, including fatalities. Elevated AST and ALT occurred in over one-third and one-quarter of patients, respectively, with a small percentage of grade 3 or 4 elevations; total bilirubin elevations (including grade 3 or 4 events) were also reported. Liver enzyme elevation may occur with or without concurrent CRS.

• Hypersensitivity reactions: Teclistamab may cause both systemic and local injection site–related reactions. A small number of patients experienced systemic administration reactions, which consisted of grade 1 recurrent pyrexia and grade 1 swollen tongue. Over one-third of patients developed injection-site reactions; most reactions were grade 1, with some grade 2 events.

• Infection: Teclistamab may cause severe, life-threatening, or fatal infections. Serious infections (including opportunistic infections) occurred in almost one-third of patients, with a similar percentage of grade 3 or 4 infections; fatal infection was reported in some patients.

• Neurologic toxicity: Teclistamab may cause serious or life-threatening neurologic toxicity, including immune effector cell-associated neurotoxicity syndrome (ICANS). In a clinical trial, over 50% of patients experienced neurologic toxicity, with grade 3 or 4 events occurring in some. Headache, motor dysfunction, sensory neuropathy, and encephalopathy were the most frequently reported neurologic toxicities. Grade 4 seizure and a case of fatal Guillain-Barre syndrome were reported with longer follow-up. ICANS was observed in some patients; most patients experienced ICANS following step-up dose 1, step-up dose 2, or the initial treatment dose. A small number of patients developed ICANS following subsequent doses. The median time to ICANS onset was 4 days (range: 2 to 8 days) with a median duration of 3 days (range: 1 to 20 days). Confusional state and dysgraphia were the most common ICANS clinical manifestations. The onset of ICANS may be concurrent with, following resolution of, or in the absence of CRS. Patients are at risk of depressed level of consciousness; advise patients to not drive or operate heavy or potentially dangerous machinery during and for 48 hours after completion of the step-up dosing schedule and with new onset of any neurologic toxicity symptoms until resolution.

Other warnings/precautions:

• REMS program: Teclistamab is available only through a restricted program under a REMS called the Tecvayli REMS Program. Further information is available at www.tecvaylirems.com or 1-855-810-8064.

Verify pregnancy status prior to treatment initiation in patients who could become pregnant. Patients who could become pregnant should use effective contraception during therapy and for 5 months after the last teclistamab dose.

Pregnancy Considerations

Animal reproduction studies have not been conducted.

Teclistamab is a humanized monoclonal antibody (IgG4). Human IgG crosses the placenta. Fetal exposure is dependent upon the IgG subclass, maternal serum concentrations, placental integrity, newborn birth weight, and gestational age, generally increasing as pregnancy progresses. The lowest exposure would be expected during the period of organogenesis and the highest during the third trimester (Clements 2020; Palmeira 2012; Pentsuk 2009).

Based on the mechanism of action, in utero exposure to teclistamab may cause fetal harm. Due to risk of hypogammaglobulinemia, consider assessing immunoglobulin levels of newborns exposed to teclistamab in utero.

Breastfeeding Considerations

It is not known if teclistamab is present in breast milk.

Teclistamab is a humanized monoclonal antibody (IgG4). Human IgG is present in breast milk; concentrations are dependent upon IgG subclass and postpartum age (Anderson 2021).

Due to the potential for serious adverse reactions in the breastfed infant, breastfeeding is not recommended by the manufacturer during therapy and for 5 months after the last dose of teclistamab.

Monitoring Parameters

Monitor blood counts, liver enzymes, and bilirubin at baseline and periodically during therapy. Monitor immunoglobulin levels during treatment. Consider laboratory testing to monitor for disseminated intravascular coagulation, as well as pulmonary, cardiac, and renal function. Verify pregnancy status prior to treatment initiation (in patients who could become pregnant).

Due to the risk for cytokine release syndrome (CRS) and neurologic toxicity, patients should be hospitalized for 48 hours after administration of teclistamab step-up doses including the first treatment dose. Monitor for CRS (signs/symptoms may include fever, hypoxia, chills, hypotension, sinus tachycardia, headache, and elevated liver enzymes) and signs/symptoms of neurologic toxicity. Monitor for signs/symptoms of infection (before and after treatment), monitor for signs of systemic or local hypersensitivity reactions.

The American Society of Clinical Oncology hepatitis B virus (HBV) screening and management provisional clinical opinion (ASCO [Hwang 2020]) recommends HBV screening with hepatitis B surface antigen, hepatitis B core antibody, total Ig or IgG, and antibody to hepatitis B surface antigen prior to beginning (or at the beginning of) systemic anticancer therapy; do not delay treatment for screening/results. Detection of chronic or past HBV infection requires a risk assessment to determine antiviral prophylaxis requirements, monitoring, and follow-up.

Mechanism of Action

Teclistamab is a humanized immunoglobulin G4-proline, alanine, alanine (IgG4-PAA) antibody, and bispecific B-cell maturation antigen (BCMA)-directed CD3 T-cell engager. Teclistamab binds to the CD3 receptor on the surface of T-cells, and BCMA expressed on the surface of multiple myeloma cells, which results in T-cell activation, the release of various proinflammatory cytokines, and the lysis of BCMA-expressing multiple myeloma cells (Moreau 2022).
