Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

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.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

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 expansion cohorts of GI-101A plus pembrolizumab

GI-101/GI-101A is a novel bi-specific Fc fusion protein containing the CD80 ectodomain as an N-terminal moiety and an interleukin (IL)-2 variant as a C-terminal moiety configurated via a human immunoglobulin G4 (IgG4) Fc.

GI-101A is an abbreviation of advanced GI-101 with an improved formulation for manufacture consistency.
