Phase 1

Interventions
Drug: HM95573, cetuximab
Registration Number

Lead Sponsor

Brief Summary

This study evaluates the safety, tolerability and pharmacokinetics of HM95573 In combination with either cobimetinib or cetuximab in patients with locally advanced or metastatic solid tumors.

Detailed Description

This is a Phase Ib, open-label, multicenter dose-escalation study designed to assess the safety, tolerability, and pharmacokinetics of oral dosing of HM95573 in combination with either cobimetinib or cetuximab in patients with histologically/cytologically confirmed, locally advanced, or metastatic solid tumors with RAS- or RAF-mutation for which standard therapies either do not exist or have proven ineffective or intolerable. Treatment will continue until disease progression, unacceptable toxicity, any other discontinuation criterion is met.

There are two stages of this study: Stage 1 and 1b, standard 3+3 dose escalation, and Stage 2, an indication-specific dose expansion. Stage 1 is designed to establish the combination MTD for cobimetinib and HM95573. Stage 1 consists of concurrent administration of cobimetinib and HM95573. Stage 1b, is designed to select the combination dose of cetuximab and HM95573 for expansion stage.

In Stage 2 expansion cohort I and II, the RD of cobimetinib and HM95573 with different dosing schedules or regimens might be investigated (which may be≤ MTDs established during dose escalation) in indication-specific expansion cohorts. Stage 2 expansion cohort III will further characterize the safety and tolerability of cetuximab in combination with HM95573.
