Study of LY3537982 in Cancer Patients With a Specific Genetic Mutation (KRAS G12C)

Official Title

A Phase 1a/1b Study of LY3537982 in Patients With KRAS G12C-Mutant Advanced Solid Tumours

Summary:

The purpose of this study is to find out whether the study drug, LY3537982, is safe and effective in cancer patients who have a specific genetic mutation (KRAS G12C). Patients must have already received or were not able to tolerate the standard of care. The study will last up to approximately 2 years.

Trial Description

Primary Outcome:

• Phase 1a: To determine the recommended phase 2 dose (RP2D) of LY3537982 monotherapy
• Phase 1b: To assess the safety and tolerability of LY3537982 when administered alone or in combination with other investigational agents

• To assess preliminary antitumour activity of LY3537982 when administered alone or in combination with other investigational agents: Objective response rate (ORR)
• To assess the preliminary antitumour activity of LY3537982 when administered alone or in combination with other investigational agents: Duration of Response (DOR)
• To assess the preliminary antitumour activity of LY3537982 when administered alone or in combination with other investigational agents: Best Overall Response (BOR)
• To assess the preliminary antitumour activity of LY3537982 when administered alone or in combination with other investigational agents: Time to response (TTR)
• To assess the preliminary antitumour activity of LY3537982 when administered alone or in combination with other investigational agents: Disease control rate (DCR)
• To assess the preliminary antitumour activity of LY3537982 when administered alone or in combination with other investigational agents: Progression-free survival (PFS)
• To assess the preliminary antitumour activity of LY3537982 when administered alone or in combination with other investigational agents: Overall survival (OS)
• To characterize the pharmacokinetics (PK) properties of LY3537982: Area under the plasma concentration versus time curve (AUC)
• To characterize the PK properties of LY3537982: Maximum drug concentration (Cmax)

This is an open-label, multicenter Phase 1 study to evaluate safety, tolerability, and preliminary efficacy of oral LY3537982 in patients with KRAS G12C-mutant solid tumours.

This study will be conducted in 2 parts, Part 1a is a dose escalation and Part 1b is a dose expansion. Part 1a will establish a recommended Phase 2 dose. Part 1b will have multiple arms of either monotherapy or in combination with other drugs.

KRAS G12C mutations will be identified through standard of care testing.
