A Phase 1/2, Open-label, Dose-escalation, and Expansion Study to Evaluate Safety, Tolerability, Pharmacokinetics, and Therapeutic Activity of GI-101 As a Single Agent and in Combination with Pembrolizumab, Lenvatinib or Local Radiotherapy in Patients with Advanced or Metastatic Solid Tumors (Keynote B59)

Description

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and therapeutic activity of GI-101/GI-101A as a single agent or in combination with pembrolizumab, lenvatinib or local radiotherapy (RT) over a range of advanced and/or metastatic solid tumors.This is a phase 1/2, open-label, dose-escalation and expansion study to evaluate the safety, tolerability and anti-tumor effect of GI-101/GI-101A as a single agent or in combination with pembrolizumab, lenvatinib or local RT over a range of advanced and/or metastatic solid tumors. This study will comprise six parts. * Part A: Dose-escalation and expansion cohorts of GI-101 monotherapy * Part B: Dose-escalation and expansion cohorts of GI-101 plus pembrolizumab * Part C: Dose-optimization and expansion cohorts of GI-101 plus lenvatinib * Part D: Dose-optimization and expansion cohorts of GI-101 plus local RT * Part E: Dose-escalation and expansion cohorts of GI-101A monotherapy * Part F: Dose-escalation and expa
