Phase 1a: it is anticipated that approximately 36 patients will be enrolled in the dose escalation phase as a single agent of the study. Additionally, up to 9 additional patients may be enrolled to confirm the safety of patients treated at the maximum tolerated dose (MTD)/recommended phase 2 dose (RP2D).~Phase 1b: approximately 36-42 patients will be enrolled in the dose escalation phase in the combination with pembrolizumab. One or more combination dose levels that could represent the combination RP2D will be expanded to a total of 12-15 patients to confirm safety and tolerability of the combination.
Phase 1, open-label dose-escalation study to determine the MTD of INV-1120 and RP2D, and to assess the DLT of INV-1120 as a single agent or in the combination with pembrolizumab. The safety, tolerability, and PK of INV-1120 as a single agent or in the combination with pembrolizumab will be assessed in adult patients with advanced solid tumors.
