PURPOSE: Treatment strategies for patients with advanced melanoma resistant to adoptive cell therapy with tumor-infiltrating lymphocytes (TILs) remain undefined. The efficacy of immune checkpoint inhibitors (ICIs) after TIL has not been previously described.
PATIENTS AND METHODS: Patients with unresectable melanoma who received ICI therapy both before and after TIL treatment were retrospectively identified at 14 international centers. Safety was evaluated among all patients that received one dose of ICI therapy after TIL. Objective response rates (ORR) were determined based on investigator-assessed Response Evaluation Criteria in Solid Tumors (RECIST) V.1.1 responses based on radiology reports. Kaplan-Meier methodology was used to estimate overall survival (OS) and melanoma-specific survival.
RESULTS: Among 133 patients assessed for response to ICI therapy after progression on TIL therapy, the ORR was 11% (n=14; 95% CI 5.9% to 17%), including 3 complete responses (2.3%) and 11 partial responses (8.3%). Among patients treated with a programmed death-1 inhibitor prior to TIL (n=121), the ORR was 8.3% (95% CI 4.0% to 15%). At a median follow-up among survivors of 21 months, median OS from post-TIL ICI was 8.8 months (95% CI 6.5 to 12 months). Among 14 patients with response to post-TIL ICI, 13 received an ICI they had not previously received. In the safety cohort (n=138), post-TIL ICI therapy-related toxicity occurred in 31 patients(22%), among which 7 patients (5.1%) experienced recurrence of an adverse event experienced with prior ICI treatment.
CONCLUSION: Efficacy with ICI after TIL was limited, with no evidence of synergistic toxicity. As TIL therapy becomes more widely available, these data highlight the need for novel therapies in this setting and support the inclusion of this population in future clinical trials.
