We conducted a phase I dose-escalation trial of radiation with ipilimumab in patients with melanoma with ≥2 metastatic lesions. Here, we report the final full clinical analysis. Patients received RT (6 or 8 Gy x 2 or 3 doses) to a single lesion followed by 4 cycles of ipilimumab.

Importance: Local failure after chemoradiotherapy (CT-RT) significantly contributes to mortality in patients with locally advanced non-small cell lung cancer (LA-NSCLC). One approach to improve local control is through targeted radiosensitization of the tumor.

Objective: To evaluate the dose-limiting toxic effects, maximally tolerated dose, and recommended phase 2 dose of the protease inhibitor nelfinavir mesylate, administered concurrently with CT-RT in patients with LA-NSCLC, and, in the phase 2 portion of the study, to estimate the objective response rate, local and distant failure rates, and overall survival.

Background: We conducted a phase I trial evaluating pembrolizumab+hypofractionated radiotherapy (HFRT) for patients with metastatic cancers.

Methods: There were two strata (12 patients each): (i) NSCLC/melanoma progressing on prior anti-PD-1 therapy, (ii) other cancer types; anti-PD-1-naive. Patients received 6 cycles of pembrolizumab, starting 1 week before HFRT.

Immune checkpoint inhibitors result in impressive clinical responses, but optimal results will require combination with each other and other therapies. This raises fundamental questions about mechanisms of non-redundancy and resistance. Here we report major tumour regressions in a subset of patients with metastatic melanoma treated with an anti-CTLA4 antibody (anti-CTLA4) and radiation, and reproduced this effect in mouse models.
