Ep 21: Lifileucel

Summary

Snoozing versus getting up before the alarm - guess which host is which. In this conversation, Sapna Patel and James Larkin discuss the recent approval of Lifileucel, a cellular therapy for melanoma. They delve into the study schema, the differences between cryopreserved and non-cryopreserved cells, and the mechanism of action involving T cells and interleukin-2. The discussion also covers the efficacy and durability of responses seen with Lifileucel, challenges related to reimbursement and access, and the future of this therapy in clinical practice. They conclude with a light-hearted wager on future approvals of Lifileucel in different countries.
