Study Details
Study Description
Brief Summary
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.

Phase 1 |
Detailed Description
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.

Arms and Interventions
| Arm | Intervention/Treatment |
|---|---|
| Other: Dose Escalation Phase 1a: Subjects will receive escalating doses of INV-1120 orally once a day until un-acceptable toxicity or disease progression. Three to six patients will be enrolled per cohort to evaluate the safety and pharmacokinetics for each dose level. After the last patient in each cohort completes Cycle 1 (DLT observation period of 28 days), the Safety Evaluation Team (SET) will evaluate the safety data and pharmacokinetic collected from Cycle 1, and make the decision whether to escalate the dose before opening the second cohort. Phase 1b: Subjects will receive escalating doses of INV-1120 orally once a day in combination with pembrolizumab until un-acceptable toxicity or disease progression, and DLT observation period of 21 days. |
