Tecartus Approval Date
Tecartus Approval Date
On July 24, 2020, the US Food and Drug Administration (FDA) granted accelerated approval to Tecartus (brexucabtagene autoleucel), a groundbreaking CAR-T cell therapy, for the treatment of adult patients with relapsed or refractory mantle cell lymphoma (MCL). Subsequently, on October 1, 2021, the FDA expanded the approval of Tecartus to include the treatment of adult patients with relapsed or refractory precursor B-cell acute lymphoblastic leukemia (ALL).
Tecartus Approval Date and Indications
A. July 24, 2020: MCL Approval
The initial approval of Tecartus was based on the impressive results of the ZUMA-2 study, which demonstrated its efficacy in treating patients with MCL who had previously undergone multiple unsuccessful treatments.
Approval basis: ZUMA-2 Study for MCL
The ZUMA-2 study was a single-arm, open-label trial that included 74 adult patients with relapsed or refractory MCL. The study’s primary endpoint was the objective response rate (ORR), which was assessed by an independent radiology review committee (IRRC). Of the 60 evaluable patients, 85% were male, and 93% were white. The median age was 65 years. The majority of patients (83%) had stage IV disease. The median number of prior treatments was three. The ORR was impressive, with many patients experiencing complete remission (CR) or partial remission (PR).
B. October 1, 2021: ALL Approval
The subsequent approval for the treatment of relapsed or refractory precursor B-cell ALL was based on the ZUMA-3 clinical trial, which further solidified Tecartus as a potent therapy for hematological malignancies.
Approval basis: ZUMA-3 Study for ALL
The ZUMA-3 study evaluated the efficacy and safety of Tecartus in adult patients with relapsed or refractory precursor B-cell ALL. The study’s primary endpoints were CR rate and CR duration. Among the 54 evaluable patients, 52% achieved CR within three months of infusion. The median follow-up time for responders was 7.1 months, and the median CR duration was not yet reached, with more than half of the patients estimated to have CR lasting over 12 months.
Pre-Treatment Chemotherapy and Mechanism of Action
Before receiving Tecartus, patients undergo chemotherapy to eliminate competing lymphocytes, ensuring the proper expansion of the infused CAR-T cells. Tecartus works by targeting the CD19 antigen found on the surface of cancerous B cells, leading to their destruction.
Safety Profile
Like other CAR-T cell therapies, Tecartus carries a risk of side effects, including cytokine release syndrome (CRS) and neurologic toxicities. However, the majority of these adverse events are manageable with appropriate monitoring and treatment.
Conclusion
Tecartus represents a significant advancement in the treatment of hematological malignancies. With its approvals for both MCL and ALL, it offers a new hope for patients who have exhausted other treatment options. As a medical expert, I recommend considering Tecartus for eligible patients, as it has demonstrated remarkable efficacy and a manageable safety profile.
