Frequently asked questions about ERAS-0015

What is ERAS-0015?

ERAS-0015 is an investigational small molecule being developed by Erasca, Inc. for the treatment of advanced or metastatic solid tumors. It is currently in Phase 1 clinical development and is not yet approved for any indication. It is being studied in adult patients with metastatic solid tumors.

What is ERAS-0015 used for?

ERAS-0015 is being studied for the treatment of advanced or metastatic solid tumors. It is an investigational therapy in Phase 1 development and has not been approved for commercial use. The ongoing trial enrolls adults 18 years and older with metastatic solid tumors.

What does ERAS-0015 target?

ERAS-0015 targets RAS, a gene that encodes proteins involved in cell signaling and growth. RAS mutations are common in cancer, and ERAS-0015 is a small molecule designed to act on this target. It is being evaluated in patients with advanced or metastatic solid tumors.

Who is developing ERAS-0015?

ERAS-0015 is being developed by Erasca, Inc., a biopharmaceutical company whose common stock trades under the ticker symbol ERAS. Erasca is the sponsor of the Phase 1 clinical trial evaluating ERAS-0015 in patients with advanced or metastatic solid tumors.

What phase is ERAS-0015 in?

ERAS-0015 is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA for any indication. The Phase 1 trial is currently recruiting participants with advanced or metastatic solid tumors.

What clinical trials is ERAS-0015 in?

ERAS-0015 is being evaluated in one active clinical trial, NCT06983743, titled A Study of ERAS-0015 in Patients With Advanced or Metastatic Solid Tumors. The trial is a Phase 1 study that is currently recruiting, with a planned enrollment of 600 participants, and it is being conducted in the United States.
