Optimizing Care for TILs, Cellular Therapy in Melanoma and Solid Tumors

In a special co-branded episode between Oncology On the Go, hosted by CancerNetwork^®, and the American Society for Transplantation and Cellular Therapy (ASTCT)’s program, ASTCT Talks, for American Pharmacists Month, a panel of oncology pharmacists discussed optimal strategies for using cellular therapies as treatment for patients with solid tumors. The panel included Brooke Adams, PharmD, BCOP, a board-certified oncology pharmacist specializing in stem cell transplantation and cellular therapy at the Orlando Health Cancer Institute in Orlando, Florida; Natalie Brumwell, PharmD, BCOP, a board-certified oncology pharmacist specializing in cellular therapy at Memorial Sloan Kettering Cancer Center in New York, New York; and Bryant A. Clemons, PharmD, a board-certified oncology pharmacist specializing in hematology, blood and marrow transplantation, and cellular therapy at the University of Kentucky’s Markey Cancer Center in Lexington, Kentucky.

The discussion focused on the use of the first commercially available tumor-infiltrating lymphocytes (TILs) for patients with unresectable or metastatic melanoma, lifileucel (Amtagvi), which the FDA granted accelerated approval statusto in February 2024.¹ The panelists first reviewed supporting data from the phase 2 C-144-01 trial (NCT02360579), in which lifileucel demonstrated an objective response rate of 31.5% (95% CI, 21.1%-43.4%), and a median duration of response that was not reached (NR; 95% CI, 4.1 months-NR) at the time of the approval. Additionally, the group highlighted considerations for dosing interleukin-2 (IL-2), including management of toxicities and when to hold or discontinue further doses.

Following a thorough breakdown of the proper conditions for using lifileucel in melanoma, the panelists concluded by discussing how to build upon an “exciting time for cellular therapy in solid tumors.” As part of optimizing the dosing of lifileucel and other cellular therapies in these patient populations, the experts exchanged ideas on how practices can collaborate across institutions and departments to expand access to novel treatments while helping providers develop comfort in administering these agents.
