A Phase 2 Study of NIR178 in Combination With PDR001 in Patients With Solid Tumors and Non-Hodgkin Lymphoma

This is an open-label multi-part, phase II study evaluating the combination of NIR178 and PDR001 in patients with advanced solid tumors and diffuse large B cell lymphoma (DLBCL). The study has three parts: * Part 1: Multi-arm Bayesian adaptive signal finding design in solid tumors and diffuse large B cell lymphoma (DLBCL) with continuous dosing of NIR178 in combination with PDR001. * Part 2: Exploration of continuous and intermittent NIR178 schedules in combination with PDR001 in patients with advanced non-small cell lung cancer (NSCLC). * Part 3: Further evaluation of optimal intermittent or continuous schedule of NIR178 in combination with PDR001 (if selected based on results of Part 2). As of protocol amendment 6, Part 3 explored the safety and pharmacokinetics of the film-coated tablet (FCT) formulation of NIR178 continuous dosing in combination with PDR001 in tiple negative breast cancer (TNBC) patients. In addition, a separate safety run-in part was conducted in Japan in order to adequately characterize the safety and pharmacokinetic profiles of NIR178 as a single-agent and in combination with PDR001. Patients enrolled in this study received NIR178 either twice daily (BID) continuously or based on the assigned intermittent schedule within 60 minutes prior to PDR001 infusion. PDR001 400 mg was administered via IV infusion over 30 minutes once every 4 weeks. Each treatment cycle was 28 days. Patients enrolled in the Japanese safety run-in part received NIR178 as single agent for the first cycle (28 days). If the patients completed Cycle 1 without experiencing dose limiting toxicities (DLTs), they initiated combination therapy with PDR001 starting Cycle 2 onwards, and continued at the same dose of NIR178. An additional cohort in the Japanese safety run-in part of the study received NIR178 in combination with PDR001 starting with Cycle 1. If the patients complete Cycle 1 without experiencing DLTs, they continued to receive combination treatment. Patients received treatment with the combination until disease progression (assessed by investigator per immune-related response criteria (iRECIST) or Cheson 2014), unacceptable toxicity, death or discontinuation from study treatment for any other reason (e.g., withdrawal of consent, start of a new anti-neoplastic therapy or at the discretion of the investigator), otherwise known as End of Treatment.
