Testing ERAS-0015 in patients with advanced solid tumors

A Phase 1 First-in-Human Open-Label Study Evaluating the Safety, Tolerability, Pharmacokinetics, Pharmacodynamics and Preliminary Efficacy of ERAS-0015 Monotherapy and in Combination in Patients Advanced Solid Tumors

Phase 1 Interventional Erasca, Inc. · NCT06983743

This study is testing a new drug called ERAS-0015 to see if it is safe and effective for people with advanced solid tumors that have certain RAS mutations.

What this trial studies

This clinical trial evaluates the safety and tolerability of ERAS-0015 in patients with advanced or metastatic solid tumors that have specific RAS mutations. It is a first-in-human, Phase 1/1b, open-label, multicenter study that begins with dose optimization of ERAS-0015 as a standalone treatment, followed by its use in combination with other cancer therapies. The study aims to determine the optimal dosing and assess the drug's effectiveness in this patient population.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with advanced or metastatic solid tumors and specific RAS mutations who have no effective standard treatment options.

Not a fit: Patients who have previously been treated with a RAS inhibitor or are currently receiving another investigational therapy may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could provide a new targeted therapy option for patients with advanced solid tumors that have limited treatment alternatives.

How similar studies have performed: While this approach is novel, similar studies targeting specific mutations in solid tumors have shown promise in the past.
