PRAME is highly and frequently expressed in NUT carcinoma, and the most common oncoprotein causing NUT carcinoma, BRD4::NUTM1, contributes to these high PRAME levels. PRAME epitopes presented by HLA class I are a previously unrecognized therapeutic vulnerability for NUT carcinoma that warrants clinical trials testing PRAME-targeted immunotherapies in this neglected patient population.

Given the favorable toxicity profile of mosunetuzumab, and rapid and durable complete responses observed in this cohort, further investigation of mosunetuzumab for the treatment of RT, as monotherapy and in combination with other novel agents or chemotherapy, is warranted. NCT02500407.
