IPG7236 in Patients With Advanced Solid Tumors

A Phase 1 Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Anti-tumor Activity of IPG7236 Administered Orally as a Single Agent in Patients With Advanced Solid Tumors

This is a Phase 1, Multi-center, Non-randomized, Open-label, Dose-escalation, and Dose Expansion Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Anti-tumor Activity of IPG7236 Administered Orally as a Single Agent in Patients with Advanced Solid Tumors.

The study will include a dose escalation phase (Part 1) and a dose expansion phase (Part 2). Each part will consist of a screening period of up to 28 days, a treatment period, an end of treatment visit and a safety follow-up of approximately 30 days after the last dose. IPG7236 will be given on an empty stomach (either one hour before or two hours after a meal) twice daily (approximately every 12 hours) in continuous 28-day cycles.
