Study Endpoints

Primary Endpoints

Phase 1b: Incidence and severity of dose-limiting toxicities (DLTs)
First 28 days of treatment

Incidence and severity of DLTs will be measured in the DLT-evaluable population during Cycle 1.

Phase 1b: Incidence and severity of adverse events (AEs)
Phase 1b study duration (approximately 1.5 years)

AEs will be graded according to the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 5.0

Phase 1b: Change in clinical laboratory abnormalities
Baseline through 30 days after end of study treatment

Changes from baseline through study treatment will be analyzed using NCI CTCAE version 5.0 grade criteria

Phase 1b: Change in Eastern Cooperative Oncology Group (ECOG) performance status
Phase 1b study duration (approximately 1.5 years)
Phase 2: Objective response rate (ORR)
Phase 2 study duration (approximately 3 years)

Objective responses will be determined per RECIST version 1.1 criteria, and the ORR will be defined as the proportion of patients with the best overall confirmed response of complete response (CR) or partial response (PR) in the Efficacy-Evaluable Population

Determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D)

ArmTypeDescription
OKI-179 + binimetinibEXPERIMENTAL -
Experimental: Phase 1 - Dose EscalationEXPERIMENTALDose escalation trial evaluating OKI-179 given orally on a daily basis. Patients will take OKI-179 orally (PO) on Days 1 - 4, 8 - 11 and 15 - 18 in 21-day cycles (± 3 days), under fasted conditions. The design is a modified 3+3 design to determine the maximum tolerated dose and allows for additional cohorts enrolling subjects with an alternative dosing schedule such as OKI-179 orally (PO) daily on Days 1 - 5, 8 - 12 and 15 - 19 per 21-day cycles or Days 1 - 21 per 21-day cycles to determine the maximum tolerated dose for continuous daily dosing.

NameTypeDescription
OKI-179 + binimetinibDRUGPhase 1b: With a 3+3 dose escalation design, enrollment in Phase 1b will proceed until the MTD has been defined or the highest dose level has been reached. OKI-179 will be administered on a 4-days-on/3-days-off schedule, while binimetinib will be administered BID continuously. Phase 2: Patients will be treated with the RP2D.

Frequently asked questions about OKI-179+ binimetinib

What is OKI-179?

OKI-179 is an investigational small molecule drug being developed by OnKure Therapeutics, Inc. for advanced solid tumors, including tumors with RAS mutations. It is a Class I HDAC inhibitor studied in Phase 1 clinical development, both as a single agent and in combination with binimetinib.

What does OKI-179 target?

OKI-179 targets HDAC, specifically the Class I histone deacetylase enzymes. It is classified as a Class I HDAC inhibitor, a small molecule designed to inhibit these enzymes in tumor cells. OnKure Therapeutics is developing it for advanced solid tumors, including RAS-mutated disease.

Who is developing OKI-179?

OKI-179 is being developed by OnKure Therapeutics, Inc., which trades under the ticker OKUR. The company has studied the drug in Phase 1 trials in advanced solid tumors, including a combination study with binimetinib in RAS pathway tumors and NRAS-mutated melanoma.

What phase is OKI-179 in?

OKI-179 is in Phase 1 development. It is investigational and has been evaluated in completed Phase 1 studies, including a Phase 1b portion of the NAUTILUS trial testing OKI-179 plus binimetinib in advanced solid tumors with RAS pathway alterations.

What clinical trials is OKI-179 in?

OKI-179 has been studied in two completed Phase 1 trials. NCT05340621, the NAUTILUS trial, tested OKI-179 plus binimetinib in RAS pathway advanced solid tumors and NRAS-mutated melanoma with 36 patients enrolled. NCT03931681 studied OKI-179 in advanced solid tumors with 34 patients enrolled. Both were conducted in the United States.
