A Phase I/Ib Study of NIZ985 Alone and in Combination With Spartalizumab

This was a phase I/Ib, open-label, global, multi-center study of subcutaneously administered NIZ985 alone and in combination with a PD-1 inhibitor in patients with advanced solid tumors and lymphoma who had progressed after obtaining a previous response to anti-PD-1/ CPI therapy at any time prior to enrollment. Previous response was defined as a radiographic complete response (CR) or a partial response (PR). Patients with stable disease (SD) lasting ≥ 6 months could also be included if the most recent regimen included CPI. The study consisted of two parts, dose escalation and dose expansion. Two separate arms were examined during the escalation portion: 1) evaluation of NIZ985 as a single agent. Spartalizumab could be added at the time of the first disease re-evaluation and 2) administration of NIZ985 and spartalizumab as a combination starting from C1D1. In dose expansion, NIZ985 was administered in combination with tislelizumab.
