Purpose: Determine the 1-year progression-free survival (PFS) rate among patients with malignant pleural mesothelioma (MPM) receiving the WT1 peptide vaccine galinpepimut-S after multimodality therapy versus those receiving control adjuvants. Experimental Design: This double-blind, controlled, two center phase II trial randomized MPM patients after surgery and another treatment modality to galinpepimut-S with GM-CSF and Montanide or GM-CSF and Montanide alone. An improvement in 1-year PFS from 50% to 70% was the predefined efficacy threshold, and 78 patients total were planned. The study was not powered for comparison between the two arms. Results: Forty-one patients were randomized. Treatment-related adverse events were mild, self-limited, and not clinically significant. On the basis of a stringent prespecified futility analysis (futility = ≥10 of 20 patients on one arm experiencing progression < 1 year), the control arm closed early. The treatment arm was subsequently closed because of the resultant unblinding. The PFS rate at 1 year from beginning study treatment was 33% and 45% in the control and vaccine arms, respectively. Median PFS was 7.4 months versus 10.1 months and median OS was 18.3 months versus 22.8 months in the control and vaccine arms, respectively.
