Cytokine release syndrome: Monitor for cytokine release syndrome (CRS); if fever, hypoxia, and hypotension occur, evaluate for other causes, and manage as appropriate. If CRS is suspected, manage according to the table below. If CRS occurs, monitor closely for cardiac and organ function until resolution of symptoms; consider antiseizure prophylaxis with levetiracetam. Monitor patients with ≥ grade 2 CRS (eg, hypotension unresponsive to fluids or hypoxia requiring supplemental oxygen) with continuous cardiac telemetry and pulse oximetry. Consider intensive care monitoring/support for severe or life-threatening CRS. Consider alternate treatment options (eg, higher corticosteroid dose, alternative anticytokine agents, anti-T-cell therapies) for CRS refractory to first line interventions (tocilizumab or tocilizumab and corticosteroids). Refractory CRS is characterized by fevers, end-organ toxicity (eg, hypoxia, hypotension) not improving within 12 hours of first line interventions, or development of hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS). If concurrent neurologic toxicity is suspected during CRS, administer more aggressive corticosteroid intervention (based on the CRS and Neurotoxicity tables), tocilizumab (according to CRS table), and antiseizure medications (according to Neurotoxicity table).

Warnings/Precautions

Concerns related to adverse effects:

• Cytokine release syndrome: Cytokine release syndrome (CRS) commonly occurred with idecabtagene vicleucel; grade 3, life-threatening, and fatal CRS has occurred. The median time to onset of CRS was 1 day (range: 1 to 23 days) and the median duration of CRS was 7 days (range: 1 to 63 days). The most common CRS manifestations included fever, chills, hypotension, tachycardia, hypoxia, fatigue, and headache. Serious events associated with CRS may include hypotension, hypoxia, hyperbilirubinemia, hypofibrinogenemia, atrial fibrillation, acute respiratory distress syndrome, hepatocellular injury, metabolic acidosis, pulmonary edema, multiple organ dysfunction, and/or hemophagocytic lymphohistiocytosis/macrophage activation syndrome (HLH/MAS). Identify CRS based on clinical presentation. Evaluate for and treat other causes of fever, hypoxia, and hypotension. CRS has been reported to be associated with findings of HLH/MAS (which is potentially life-threatening), as signs/symptoms may overlap. Evaluate for evidence of HLH/MAS for progressive or refractory CRS symptoms (despite treatment). The rate and duration of CRS may be dose-related, with higher idecabtagene vicleucel doses associated with a higher CRS rate and a slightly longer CRS duration; higher idecabtagene vicleucel doses were also associated with a higher requirement for tocilizumab and corticosteroid utilization. A minimum of 2 tocilizumab doses must be available prior to idecabtagene vicleucel infusion. Patients should seek immediate medical attention if signs/symptoms of CRS occur at any time. Initiate supportive care, tocilizumab, and/or corticosteroids as indicated.

• Cytomegalovirus reactivation: Cytomegalovirus infection resulting in pneumonia and death has occurred following idecabtagene vicleucel.

• Cytopenias: Prolonged cytopenias, including grades 3 and 4 neutropenia, thrombocytopenia, and anemia, may occur following lymphodepleting chemotherapy and idecabtagene vicleucel. The incidence of prolonged cytopenias may be related to the idecabtagene vicleucel dose. The median time to recovery following idecabtagene vicleucel infusion was 1.9 months for grade 3 or 4 neutropenia and 2.1 months for grade 3 or 4 thrombocytopenia. The median time to cytopenia recovery was similar among the idecabtagene vicleucel doses administered. Although rare, some patients required stem cell therapy (with autologous or allogeneic cells) for hematopoietic reconstitution due to prolonged cytopenia; fatal cases of complications (due to bleeding or infection) resulting from prolonged cytopenia occurred (in the setting of ongoing or prior CRS or HLH/MAS).

• Hemophagocytic lymphohistiocytosis/macrophage activation syndrome: HLH/MAS has occurred with idecabtagene vicleucel, including rare fatal cases of multiorgan HLH/MAS with CRS or with pulmonary fungal infection. Three cases of grade 2 HLH/MAS resolved. The incidence of HLH/MAS may be dose related. The median time to onset of HLH/MAS was 7 days (range: 4 to 9 days) and occurred in the setting of ongoing or worsening CRS. HLH/MAS with overlapping neurotoxicity has been observed. Manifestations of HLH/MAS include hypotension, hypoxia, multiple organ dysfunction, kidney dysfunction, and cytopenia. If not recognized and managed early, HLH/MAS may be life-threatening.

• Hepatitis B virus reactivation: Hepatitis B virus reactivation (sometimes resulting in fulminant hepatitis, hepatic failure, and death) can occur in patients treated with medication directed against plasma cells.

• Hypersensitivity: Allergic reactions may occur with idecabtagene vicleucel.

• Hypogammaglobulinemia: Hypogammaglobulinemia and plasma cell aplasia may occur in patients receiving idecabtagene vicleucel.

• Infections: Infections have occurred commonly with idecabtagene vicleucel; severe, life-threatening, or fatal infections have occurred. Infections included bacterial, viral, and fungal infections, as well as infection with unspecified pathogens. Neutropenic fever has been observed and may be concurrent with CRS.

• Neurotoxicity: Neurologic toxicities, which may be severe or life-threatening, have occurred with idecabtagene vicleucel, including grade 3 neurotoxicity. Neurotoxicity may occur concurrently with CRS, after CRS resolution, or in the absence of CRS. Neurotoxicity may overlap with CRS, with the onset of neurologic toxicity either after, before, or on the same day as CRS. The median time to onset of neurotoxicity was 2 days (range: 1 to 42 days). Neurotoxicity resolved in most patients, with a median duration of 6 days (range: up to ~1.5 years); cases of ongoing grade 2 neurotoxicity or tremor have occurred. For patients experiencing resolution, the median time to resolution was 5 days (range: 1 to 61 days). Grade 3 neurotoxicity may be dose related. Frequent manifestations of neurotoxicity include encephalopathy, tremor, aphasia, and delirium. Idecabtagene vicleucel has been associated with grade 3 parkinsonism, grade 3 myelitis, grade 4 neurotoxicity, and cerebral edema in multiple myeloma studies. Evaluate neurologic symptoms and treat promptly; rule out other causes of neurologic symptoms. Patients should seek immediate medical attention for signs/symptoms of neurologic toxicity. Due to the potential for neurologic events, including altered mental status or seizures, patients receiving idecabtagene vicleucel are at risk for altered or decreased consciousness or coordination in the 8 weeks following administration. Patients should refrain from driving and other hazardous activities for at least 8 weeks following idecabtagene vicleucel cell infusion.

• Secondary malignancies: Patients treated with idecabtagene vicleucel may develop secondary malignancies. If a secondary malignancy develops, contact the manufacturer (1-888-805-4555) for reporting and to obtain patient sampling instructions for origin testing.

Concurrent drug therapy issues:

• Immunizations: Vaccination with live virus vaccines is not recommended for at least 6 weeks prior to the start of lymphodepleting chemotherapy, during idecabtagene vicleucel treatment, and until immune recovery following treatment with idecabtagene vicleucel. Immunization with live viral vaccines during or following idecabtagene vicleucel has not been studied.

Special populations:

• Elderly: The incidence of grade 3 neurotoxicity was higher in patients ≥65 years of age.

Dosage form specific issues:

• Dimethyl sulfoxide: Idecabtagene vicleucel contains dimethyl sulfoxide (DMSO), which has been associated with serious hypersensitivity reactions (including anaphylaxis).

Other warnings/precautions:

• REMS program: Idecabtagene vicleucel is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS) called the ABECMA REMS. Information is available at https://www.AbecmaREMS.com or at 1-888-423-5436.

Patients vaccinated less than 14 days before initiating or during therapy should be revaccinated at least 3 after therapy is complete. Risk D: Consider therapy modification

Vaccines (Live): Immunosuppressants (Miscellaneous Oncologic Agents) may enhance the adverse/toxic effect of Vaccines (Live). Specifically, the risk of vaccine-associated infection may be increased. Immunosuppressants (Miscellaneous Oncologic Agents) may diminish the therapeutic effect of Vaccines (Live). Risk X: Avoid combination

Yellow Fever Vaccine: Immunosuppressants (Miscellaneous Oncologic Agents) may enhance the adverse/toxic effect of Yellow Fever Vaccine. Specifically, the risk of vaccine-associated infection may be increased. Immunosuppressants (Miscellaneous Oncologic Agents) may diminish the therapeutic effect of Yellow Fever Vaccine. Risk X: Avoid combination

Reproductive Considerations

Verify pregnancy status prior to treatment initiation.

Refer to monographs of concomitant medications for contraception recommendations; recommendations specific to idecabtagene vicleucel are not available.

Pregnancy Considerations

Animal reproduction studies have not been conducted. Based on the mechanism of action, fetal plasma cell aplasia or hypogammaglobulinemia may occur following in utero exposure. Monitor immunoglobulin levels in newborns.

Breastfeeding Considerations

It is not known if idecabtagene vicleucel is present in breast milk.

According to the manufacturer, the decision to breastfeed during therapy should consider the risk of infant exposure, the benefits of breastfeeding to the infant, and the benefits of treatment to the mother.

Monitoring Parameters

Screen for hepatitis B virus (HBV), hepatitis C virus, and HIV in accordance with clinical guidelines prior to collection of cells for manufacturing. Monitor CBC prior to and after idecabtagene vicleucel administration. Evaluate pregnancy status prior to use (in patients who may become pregnant). Monitor immunoglobulin levels (IgG) after idecabtagene vicleucel treatment.

Monitor for cytokine release syndrome (CRS) and signs/symptoms of neurotoxicity during therapy and for at least 4 weeks after infusion. For ≥ grade 2 CRS, perform continuous cardiac telemetry and pulse oximetry. Monitor patient daily at the health care facility for at least 7 days after cell infusion. Monitor for signs/symptoms of infection before and after idecabtagene vicleucel administration. Monitor for signs/symptoms of cytomegalovirus and HBV reactivation. Monitor for hypersensitivity. Evaluate for evidence of hemophagocytic lymphohistiocytosis/macrophage activation syndrome. Monitor (lifelong) for secondary malignancies.

The American Society of Clinical Oncology 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

Idecabtagene vicleucel is a B-cell maturation antigen (BCMA)-directed genetically modified autologous T-cell immunotherapy in which a patient's T-cells are reprogrammed via transduction with an anti-BCMA02 chimeric antigen receptor (CAR) lentiviral vector. The CAR construct includes an anti-BCMA single chain variable fragment-targeting domain for antigen specificity, a transmembrane domain, a CD3-zeta T-cell activation domain, and a 4-1BB costimulatory domain. CD3-zeta signaling initiates activation and antitumor activity, while 4-1BB (CD137) signaling enhances T-cell expansion. Antigen-specific activation of idecabtagene vicleucel results in CAR-positive T-cell proliferation, cytokine secretion, and subsequent cytolytic killing of BCMA-expressing cells. Idecabtagene vicleucel is prepared from the patient's T-cells, which are obtained via leukapheresis.

Pharmacokinetics

Note: Idecabtagene vicleucel exhibits an initial rapid expansion followed by a bi-exponential decline. Patients who received tocilizumab and/or corticosteroids to manage cytokine release syndrome (CRS) and/or neurologic toxicity experienced higher idecabtagene vicleucel expansion levels and higher AUC0 to 28d and Cmax compared to patients who did not receive tocilizumab or corticosteroids.

Duration: Idecabtagene can persist in peripheral blood for up to 1 year after infusion.

Time to peak: Median time to maximal expansion (in peripheral blood): 11 days after infusion.
