Brief Summary:
This phase 1 first-in-human (FIH) dose escalation study will determine the maximum tolerated dose (MTD) of KO-947 in subjects with locally advanced unresectable or metastatic, relapsed and/or refractory, non-hematological malignancies. If an MTD cannot be identified, a recommended phase 2 dose (RP2D) will be determined. In addition, two tumor specific extension cohorts may be conducted to further characterize the safety and tolerability of KO-947 and provide preliminary evidence of anti-tumor activity.

Condition or disease Intervention/treatment Phase
Advanced Malignant Neoplasm Drug: KO-947 Phase 1

Detailed Description:

This phase 1 first-in-human (FIH) dose escalation study will determine the maximum tolerated dose (MTD) of KO-947 in subjects with locally advanced unresectable or metastatic, relapsed and/or refractory, non-hematological malignancies. If an MTD cannot be identified, a recommended phase 2 dose (RP2D) will be determined. In addition, two tumor specific extension cohorts may be conducted to further characterize the safety and tolerability of KO-947 and provide preliminary evidence of anti-tumor activity. Screening evaluations will be completed following signing of informed consent and within 4 weeks (28 days) of Cycle 1 Day 1. Evaluations performed as part of the standard of care within 28 days of dosing but prior to consent do not need to be repeated. By signing the consent form, study subjects agree to the collection of standard of care health information.

The study will consist of three parts: dose escalation, MTD expansion and tumor specific extension.
