EP102 to target METTL3 in advanced solid tumors

A Phase 1 Multicenter, Open-Label, Dose-Escalation, Safety, Pharmacokinetic, Pharmacodynamic, and Clinical Activity Study of Orally Administered EP102 Monotherapy in Participants With Advanced Solid Tumors

Phase 1 Interventional Epics Therapeutics · NCT07163325

This will test EP102, a drug that targets METTL3, in adults with advanced solid tumors who have no standard treatment options or whose cancer progressed after prior therapies.

What this trial studies

This first-in-human, Phase 1 dose-escalation trial gives EP102 to adults with a variety of advanced solid tumors to define the maximum tolerated dose and overall safety profile. The study collects pharmacokinetic (PK) and pharmacodynamic (PD) measurements and enrolls patients with measurable disease who have exhausted or have no standard treatments. Investigators will also perform an exploratory evaluation of antitumor activity using RECIST v1.1 criteria. Results will inform recommended doses for subsequent dose-optimization and efficacy studies.

Who should consider this trial

Good fit: Ideal candidates are adults with histologically confirmed locally advanced or metastatic solid tumors of the listed cancer types who have at least one measurable lesion per RECIST v1.1 and have received at least one prior line of systemic therapy or have no available standard treatment.

Not a fit: Patients with cancers not listed, without measurable disease, who still have effective standard treatment options, or who cannot tolerate risks of a first-in-human dose-escalation study are unlikely to benefit.

Why it matters

Potential benefit: If successful, EP102 could offer a new treatment option for patients with advanced solid tumors driven by METTL3-related biology.

How similar studies have performed: Modulating METTL3 is a novel therapeutic approach with encouraging preclinical data but limited prior clinical evidence, and EP102 represents a first-in-human test of this mechanism.

* Participants with known dysphagia, short-bowel syndrome, gastroparesis, or any condition that may impair the ingestion or gastrointestinal absorption of orally administered drugs.
* Pregnant or breastfeeding participants.
* Participants who have received IMP or devices in other clinical trials within four weeks before the first dose.
* Participants with prior exposure to selective METTL3 inhibitor therapy.
