The US Food and Drug Administration (FDA) has approved tisagenlecleucel (Kymriah®) for its second indication.
The chimeric antigen receptor (CAR) T-cell therapy is now approved to treat adults with relapsed or refractory large B-cell lymphoma after 2 or more lines of systemic therapy.
This includes patients with diffuse large B-cell lymphoma (DLBCL) not otherwise specified, high grade B-cell lymphoma, and DLBCL arising from follicular lymphoma.
The application for tisagenlecleucel in B-cell lymphoma was granted priority review. The FDA aims to take action on a priority review application within 6 months of receiving it, rather than the standard 10 months.
Tisagenlecleucel is also FDA-approved to treat patients age 25 and younger who have B-cell precursor acute lymphoblastic leukemia that is refractory or in second or later relapse.
Access to tisagenlecleucel
The prescribing information for tisagenlecleucel includes a boxed warning detailing the risk of cytokine release syndrome (CRS) and neurological toxicities for patients receiving tisagenlecleucel.
Because of these risks, tisagenlecleucel is only available through a Risk Evaluation and Mitigation Strategy (REMS) program. The REMS program serves to inform and educate healthcare professionals about the risks associated with tisagenlecleucel treatment.
Novartis, the company marketing tisagenlecleucel, has established a network of certified treatment centers throughout the US. Staff at these centers are trained on the use of tisagenlecleucel and appropriate patient care.
Tisagenlecleucel is manufactured at a Novartis facility in Morris Plains, New Jersey. In the US, the target turnaround time for manufacturing tisagenlecleucel is 22 days.
Tisagenlecleucel costs $475,000 for a single course of treatment. However, Novartis said it is collaborating with the US Centers for Medicare and Medicaid Services on the creation of an appropriate value-based pricing approach.
The company also has a program called KYMRIAH CARES™, which offers financial assistance to eligible patients to help them gain access to tisagenlecleucel.
Phase 2 trial
The FDA approval of tisagenlecleucel for adults with relapsed/refractory B-cell lymphoma is based on results of the phase 2 JULIET trial.
The prescribing information for tisagenlecleucel includes data on 106 patients treated on this trial.
Only 68 of these patients were evaluable for efficacy. They had a median age of 56 (range, 22 to 74), and 71% were male.
Seventy-eight percent of patients had primary DLBCL not otherwise specified, and 22% had DLBCL following transformation from follicular lymphoma. Seventeen percent had high grade DLBCL.
Fifty-six percent of patients had refractory disease, and 44% had relapsed after their last therapy. The median number of prior therapies was 3 (range, 1 to 6), and 44% of patients had undergone autologous transplant.
Ninety percent of patients received lymphodepleting chemotherapy (66% fludarabine and 24% bendamustine) prior to tisagenlecleucel, and 10% did not. The median dose of tisagenlecleucel was 3.5 × 108 CAR+ T cells (range, 1.0 to 5.2 × 108).
The overall response rate was 50%, with 32% of patients achieving a complete response and 18% achieving a partial response. The median duration of response was not reached with a median follow-up of 9.4 months.
In all 106 patients infused with tisagenlecleucel, the most common grade 3/4 adverse events were infections (25%), CRS (23%), neurologic events (18%), febrile neutropenia (17%), encephalopathy (11%), lymphopenia (94%), neutropenia (81%), leukopenia (77%), anemia (58%), thrombocytopenia (54%), hypophosphatemia (24%), hypokalemia (12%), and hyponatremia (11%).
Three patients died within 30 days of tisagenlecleucel infusion. All of them had CRS and either stable or progressive disease. One of these patients developed bowel necrosis.
One patient died of infection. There were no deaths attributed to neurological events, and no fatal cases of cerebral edema.
