An Open-label, Multicenter, Dose Escalation and Expansion Phase 1/2 Study to Evaluate the Safety, Tolerability and Pharmacokinetics, and Anti-tumor Activity of GI-102, a CD80-IgG4 Fc-IL-2v Bispecific Fusion Protein, As a Single Agent and in Combination with Conventional Anti-cancer Drugs, Pembrolizumab or Trastuzumab Deruxtecan(T-DXd) in Patients with Advanced or Metastatic Solid Tumors (KEYNOTE-G08)

Description

The purpose of this study is to evaluate the safety, tolerability, pharmacokinetics, and therapeutic activity of GI-102 as a single agent and in combination with conventional anti-cancer drugs, pembrolizumab or trastuzumab deruxtecan(T-DXd) 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-102 as a single agent and in combination with conventional anti-cancer drugs, pembrolizumab or trastuzumab deruxtecan(T-DXd) over a range of advanced and/or metastatic solid tumors. This study is adaptive in nature. The study is composed of four parts: * Part A: Dose escalation and optimization phase of GI-102 intravenous (IV) monotherapy * Part A dose escalation phase * Part A dose optimization phase: Dose optimization cohorts in patients with 2L+, CPI-refractory metastatic melanoma * Part B: Dose escalation and expansion phase of GI-102 subcutaneous (SC
