Brief Summary

A Phase 1 dose escalation study in patients with advanced solid tumors harboring KRAS G12C mutation to determine the maximum tolerated dose and recommended Phase II dose of HBI-2438 and characterize its pharmacokinetic profile.

Detailed Description

A Phase 1, Open-Label, Dose Escalation of HBI-2438 in Patients with Advanced Malignant Solid Tumors Harboring KRAS G12C Mutation. The primary and secondary objectives are:

1. To determine the MTD and recommended Phase 2 dose (RP2D) of HBI-2438 as an oral monotherapy for advanced solid tumors harboring KRAS G12C mutation.

2. To characterize the PK of HBI-2438 in subjects with advanced malignant solid tumors harboring KRAS G12C mutation.

HBI-2438 is an orally administered KRAS G12C Inhibitor and will be dosed once daily throughout the escalation and expansion phase. Up to 44 subjects will be enrolled sequentially into the 3+3 dose escalation and monitored throughout the study for safety and tolerability. The dose escalation phase will consist of 6 cohorts, with doses ranging from 150 to 1200mg. Once the MTD of RP2D is established, an additional 6-8 subjects with brain metastases will be enrolled into the expansion phase at that dose level.

Dose Escalation and ExpansionHBI-2438HBI-2438 will be given orally in ascending doses (escalation cohort), until the maximum tolerated dose or recommended Phase 2 dose is reached. Up to 6-8 patients will then be enrolled in the expansion cohort at the recommended dose.
