SITC22 Reactions - Lifileucel

SITC22 Reactions - Lifileucel

Author

Abstract #O789: Amod Sarnaik presented pooled efficacy and safety data from two cohorts of the P2 C-144–01 trial in progress, assessing lifileucel in 153 heavily pre-treated patients with advanced melanoma after progression on ICI.

Results: Lifileucel demonstrated a 31% ORR. Median DOR not reached at 36.5 months, with 41.7%of responses maintained at ≥24 months. 79.3% of patients had a reduction in tumor burden. Safety profile consistent with that of NMA-LDand IL-2.

Objective response rate

Thought leader reactions were positive, with several experts saying that TIL should get accelerated approval for use in this difficult to treat population, as it provided meaningful clinical benefit with reasonable safety.

Of particular interest was the durability of response to lifileucel.

Summary: This analysis of patients treated with lifileucel represents a positive step for heavily-pretreated, advanced melanoma patients, a population with limited treatment options. Thought leaders feel that TIL therapies should be approved in this population, as durable and appreciable efficacy was achieved with no serious safety concerns.

79% had reduction in disease. ORR 31%. Many responses deepen over time.

Median DOR not yet reached. Median OS 13.9 mo. 12 mo OS was 54%. As typical with immunotherapy, we see a nice tail on the curve. #TIL#SITC22

Important work on efficacy of TIL therapy lifileucel in PD-1 resistant #melanoma being presented at #SITC22. Pretty good durability for this heavy lift of a treatment.

Toxicity profile was in line with prior TIL/Lifileucel data. No surprises here. Median # doses of IL-2 was 6.

Absolutely agree!… this should be available to our melanoma patients ASAP!… and paves the way for smarter cellular therapies to be designed, studied, and eventually widely disseminated

Where does this leave us with #TIL therapy for #melanoma? IMO, this response rate/durability justifies accelerated approval. Pts with PD-1 refractory melanoma need options. It’s FAR from a perfect tx but provides meaningful clinical benefit. What say you melanoma Twitterverse?
