Brief Summary

A Phase 1 dose escalation study in patients with advanced solid tumors harboring KRAS or EGFR mutations to determine the maximum tolerated dose and recommended Phase II dose of HBI-2376 and characterize its pharmacokinetic profile.

Detailed Description

A Phase 1, Open-Label, Dose Escalation of HBI-2376 in Patients with Advanced Malignant Solid Tumors Harboring KRAS or EGFR Mutations. The primary and secondary objectives are:

1. To determine the MTD and recommended Phase 2 dose (RP2D), of HBI-2376 as an oral monotherapy for advanced solid tumors harboring KRAS or EGFR mutations

2. To characterize the PK of HBI-2376 in subjects with advanced malignant solid tumors harboring KRAS or EGFR mutations

HBI-2376 is a SHP2 Inhibitor and will be dosed once daily throughout the escalation and expansion phase. Up to 42 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 6 to 40mg. Once the MTD of RP2D is established, additional 6 subjects will be enrolled into the expansion phase at that dose level.

Dose Escalation and ExpansionHBI-2376HBI-2376 will be given orally in ascending doses (escalation cohort), until the maximum tolerated dose or recommended Phase 2 dose is reached. Up to 6 patients will then be enrolled in the expansion cohort at the recommended dose.
Primary Outcome Measures
NameTimeMethod
To determine the maximum tolerated dose (MTD) and recommended Phase 2 dose (RP2D), of HBI-2376 as an oral monotherapy for advanced solid tumors harboring KRAS or EGFR mutations.Up to 36 months

Safety endpoints: Incidence of dose-limiting toxicities (DLTs), adverse events (AEs), and serious adverse events (SAEs) overall, by severity, by relationship to HBI-2376, and those that led to discontinuation of HBI-2376
