7 de junio de 2026 actualizado por: Shenzhen Ionova Life Sciences Co., Ltd.

A Phase I/II, Open-Label, Multi-Center, Dose Escalation and Cohort Expansion Clinical Study to Evaluate the Safety, Tolerability, Pharmacokinetics, and Preliminary Antitumor Activity of INV-8989 in Patients With Advanced Solid Tumors Harboring KRAS G12D Mutations

This is a Phase 1 and Phase 2 study to evaluate the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of INV-8989 in patients with advanced solid tumors harboring KRAS G12D mutations.

Descripción general del estudio

Descripción detallada

This is a Phase 1 and Phase 2 study to evaluate the safety, tolerability, pharmacokinetics, and preliminary antitumor activity of INV-8989 in patients with advanced solid tumors harboring KRAS G12D mutations.

The entire study consists of two parts: Phase 1 for dose escalation and Phase 2 for dose expansion and indication exploration.

Phase 1 dose escalation of INV-8989 follows a real time monitored, PK/PD and safety guided scheme with an accelerated titration plus traditional 3+3 design for DLT assessment.

Phase 2 aims to reassure the safety profile and better define efficacy. Phase 2 consists of Phase 2a and Phase 2b.

Phase 2a study aims to further confirm the safety profile of INV-8989 through a larger number of patients, clarify its PK characteristics and preliminary efficacy, and optimize the recommended Phase 2 dose (RP2D).

The Phase 2b study aims to explore the anti-tumor efficacy of INV-8989 in the patients with different types of advanced solid tumors harboring the KRAS G12D mutation, and those who have failed previous standard treatments.
