Clinical Trial Summary

The purpose of this Phase I, Multi-Center, Open-Label Study is to evaluate the safety, tolerability, Pharmacokinetics, Pharmacodynamics and anti-tumor activity of KF-0210 in participants with advanced solid tumors. The study will be conducted in two parts: phase Ia, and phase Ib.

Description:

Phase 1a:

The primary objective of the phase 1a part of the study is to evaluate the safety, tolerability, pharmacokinetics, pharmacodynamic and anti-tumor activity of oral KF-0210 as a single agent in participants with advanced solid tumors, to identify the dose-limiting toxicity and establish the maximum tolerated dose, or maximum administered dose and/or the recommended Phase II dose of KF-0210 in participants with advanced solid tumors.

Phase 1b:

The primary objective of the phase 1b part of the study is to assess the safety, pharmacokinetics, pharmacodynamic and anti-tumor activity of KF-0210 in combination with Atezolizumab in patients with colorectal cancer (CRC) (MSS), lung cancer (LC), squamous cell carcinoma of the esophagus (SCCE), gastric cancer (GC), and bladder cancer (BC).
