FDA Accelerated Approval of Kymriah for Follicular Lymphoma
June 2022: After two or more lines of systemic therapy, the FDA awarded tisagenlecleucel (Kymriah, Novartis Pharmaceuticals Corporation) expedited approval for adult patients with relapsed or refractory follicular lymphoma (FL).
The approval was based on the results of the ELARA trial (NCT03568461), a multicenter, single-arm, open-label trial evaluating tisagenlecleucel, a CD19-directed chimeric antigen receptor (CAR) T cell therapy, in adult patients who were refractory or relapsed within 6 months after completing two or more lines of systemic therapy (including an anti-CD20 antibody and an alkylating agent) or Tisagenlecleucel was given as a single intravenous infusion after lymphodepleting chemotherapy, with a target dosage of 0.6 to 6.0 x 108 CAR-positive viable T cells.
Safety Profile and Common Adverse Reactions
The overall response rate (ORR) and duration of response (DOR), as established by an independent review committee, were the major efficacy measures. The ORR was 86 percent (95 percent CI: 77, 92) among 90 patients in the primary efficacy analysis, with a CR rate of 68 percent (95 percent CI: 57, 77). The median DOR was not met, with 75% of respondents (95 percent CI: 63, 84) still responding after 9 months. The ORR was 86 percent (95 percent CI: 77, 92) for all patients who had leukapheresis (n=98), with a CR rate of 67 percent (95 percent CI: 57, 76).
Cytokine release syndrome, infection, weariness, musculoskeletal pain, headache, and diarrhoea were the most prevalent adverse effects in patients (>20 percent). 0.6 to 6.0 x 108 CAR-positive viable T cells is the suggested tisagenlecleucel dose.
How CancerFax Helps
CancerFax is a specialist cancer access and patient-navigation platform. We help patients and families understand their options, organise medical records, coordinate hospital communication, and support cross-border treatment planning where appropriate.
We help collect and organise reports, scans, pathology, biomarker results, and treatment history for structured case review.
We communicate with hospitals or trial teams to assess whether a case may be suitable for further screening.
We support appointment coordination, document submission, translation, and direct communication with international departments.
For international patients, we help with practical coordination — travel planning, hospital admission guidance, and local support.
If this option is not suitable, we help explore other relevant treatments, clinical trials, or advanced care pathways.
From inquiry through to follow-up, our coordinators provide a single point of contact for the family.
CancerFax does not guarantee treatment access, eligibility, or clinical outcome. Our role is to help patients access accurate information, structured review, and appropriate specialist pathways.
