| Summary: | I
the proliferation of intra-tumour CD8+ T cells is directly correlated with the clinical response, making tumour-infiltrating lymphocytes (TILs) a treatment of interest in combination with a PD-1 inhibitor, which is the undisputed gold standard in the management of metastatic melanoma. The aim of this trial was, therefore, to evaluate the safety and efficacy of sequential combination therapy consisting of nivolumab (a PD-1 inhibitor) and TILs adoptive T cells in patients with metastatic melanoma.
Materials and methods: We performed an exploratory, prospective, single-centre, open-label, non-randomised, uncontrolled phase I/II study. We enrolled 10 previously untreated patients with advanced melanoma. The treatment regimen was neoadjuvant anti-PD-1 therapy followed by 2 injections of TILs and a second sequence of anti-PD-1 therapy.
Results and interpretation: Among the four patients who received the autologous TILs + nivolumab combination, three (75%) achieved an objective response (two achieved a partial response [PR] at the end of the study, two achieved a complete response [CR]), and one achieved a CR at the end of the study. Among these three patients, one had a PR, and two had stable disease (SD) after the nivolumab course and before any TILs administration, reinforcing the importance of the tumour response after TILs injection. These responses were persistent, ranging from 9 months to 3.4 years.
