Read moreFDA Approves Tecelra, First T Cell Therapy for Solid Tumors
On August 2, 2024, the FDA granted accelerated approval for Tecelra (afamitresgene autoleucel) a melanoma-associated antigen A4 (MAGE-A4)-directed genetically modified autologous T cell immunotherapy indicated for the treatment of adults with unresectable or metastatic synovial sarcoma who have received prior chemotherapy, are HLA-A*02:01P, -A*02:02P, 16 -A*02:03P, or -A*02:06P positive and whose tumor expresses the MAGE-A4 antigen as determined by FDA-approved or cleared companion diagnostic devices. Tecelra is contra-indicated in adults who are heterozygous or 52 homozygous for HLA-A*02:05P.[i]
Synovial sarcoma is an uncommon and aggressive cancer that can form in soft tissues such as muscles, fat, joint linings, and ligaments. It is often found in the arm, leg, or foot, and near joints such as the wrist or ankle. It can also form in soft tissues in the lung or abdomen. Although synovial sarcoma can affect people at any age, it is known to occur more commonly in adolescents and adults younger than 30.[ii] Adults with metastatic synovial sarcoma at diagnosis have a 5-year overall survival rate of 10%, versus 76% for those with localized disease at diagnosis.[iii]
Synovial sarcoma (SS) accounts for up to 10% of all soft-tissue sarcomas. In the US, 800-1000 new cases of SS are diagnosed annually. According to an analysis of the Surveillance, Epidemiology, and End Results (SEER) database study, the age-adjusted incidence rate of SS in the US is 0.177 per 100,000 (approximately 580 incident cases) with a prevalence rate of 0.65 per 100,000 (approximately 2129 prevalent cases).[iv]
Tecelra is an autologous T cell immunotherapy composed of a patient’s own T cells. T cells in Tecelra are modified to express a TCR that targets MAGE-A4 expressed by cancer cells in synovial sarcoma. After the patient undergoes leukapheresis, cells are sent for manufacturing. It takes about six weeks for the Tecelra to be returned to the provider, though that time may vary.
The patient is admitted to the hospital and receives a lymphodepleting chemotherapy regimen of fludarabine 30 mg/m2/day intravenously for four days starting on the seventh day before Tecelra infusion (Day-7 to Day -4), and cyclophosphamide 600 mg/m2/day intravenously for 3 days starting the seventh day before Tecelra infusion (Day -7 to Day -5). Tecelra is administered over an hour as a single intravenous infusion on Day 1. The patient will remain hospitalized for at least seven days after the infusion. The patient should plan to stay close to a healthcare facility for at least four weeks.[v]
The safety and effectiveness of Tecelra were evaluated in a multicenter, open-label clinical trial. Effectiveness was evaluated based on overall response rate and the duration of response to treatment with Tecelra. Among the 44 patients in the trial who received Tecelra, the overall response rate was 43.2% and the median duration of response was six months. Tecelra was approved under an accelerated approval pathway and a confirmatory trial is ongoing to verify Tecelra’s clinical benefit.[vi]
A Black Box Warning has been issued because patients may experience cytokine release syndrome. Patients may also exhibit Immune Effector Cell-associated Neurotoxicity Syndrome (ICANS).
The current list price for Tecelra is $727,000. This does not include the pre-treatment or hospitalization costs associated with the administration of the therapy.
