Frequently asked questions about IDE397

What is IDE397 used for in solid tumors?

IDE397 is an investigational small molecule being studied for the treatment of solid tumors that harbor a MTAP deletion. It is currently in Phase 1 clinical development for this patient population.

What does IDE397 target?

IDE397 targets MAT2A, an enzyme involved in cancer cell metabolism. By inhibiting MAT2A, the drug is designed to exploit vulnerabilities in tumors with MTAP deletions, potentially leading to cancer cell death.

Who makes IDE397?

IDE397 is being developed by IDEAYA Biosciences, Inc., a biopharmaceutical company traded on the NASDAQ under the ticker symbol IDYA.

What phase is IDE397 in?

IDE397 is currently in Phase 1 clinical development. It is an investigational drug and has not yet been approved by regulatory authorities.

What clinical trials is IDE397 in?

IDE397 is being evaluated in a Phase 1 clinical trial with the identifier NCT04794699. This study is investigating the drug in participants with solid tumors harboring MTAP deletion and is active but not recruiting.

Is IDE397 the same as other names?

IDE397 is the primary name for this investigational drug. No alternative names have been reported for this asset.
