Treatment Arms

ArmTypeDescription
OPM-101 (in combination with pembrolizumab)EXPERIMENTALOPM-101 will be administered as hard gelatin capsules twice a day for 24 weeks. In the Phase 1b, 2 doses of OPM-101 will be considered: 75 mg bid and 150 mg bid. At the end of this Phase 1b, a recommended dose for Phase 2a will be determined. During the Phase 2a, the recommended dose of OPM-101 will be administered bid over 24 weeks. OPM-101 will be administered in combination with authorized regimen of Pembrolizumab.

Interventions

Frequently asked questions about OPM-101

What is OPM-101 used for in advanced melanoma?

OPM-101 is an investigational small molecule being studied for the treatment of advanced melanoma, specifically in patients whose disease has shown resistance to anti-PD-1 therapy. It is being evaluated in combination with an anti-PD-1 agent in a Phase 1 clinical trial.

What does OPM-101 target?

OPM-101 is a small molecule, but its specific molecular target has not been disclosed. The drug is being studied in combination with anti-PD-1 therapy for advanced melanoma, and the trial is biomarker-selected, meaning patients are chosen based on specific biological markers.

Who is developing OPM-101?

OPM-101 is being developed by Precision BioSciences, Inc., a biopharmaceutical company traded on the Nasdaq under the ticker symbol DTIL. The company is conducting a Phase 1 clinical trial of the drug in advanced melanoma.

What phase is OPM-101 in?

OPM-101 is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA. The ongoing Phase 1 trial is assessing its safety and efficacy in combination with anti-PD-1 therapy for advanced melanoma.

What clinical trials is OPM-101 in?

OPM-101 is being evaluated in a single Phase 1 clinical trial with the identifier NCT07040436. This open-label, uncontrolled study is assessing the safety and efficacy of OPM-101 combined with anti-PD-1 in patients with advanced melanoma showing resistance to anti-PD-1. The trial is not yet recruiting and plans to enroll 41 participants.
