Frequently asked questions about Marlotamig

What is Marlotamig used for?

Marlotamig is an investigational therapy being studied in adults with advanced solid tumors. It is being evaluated in combination with cemiplimab, another Regeneron therapy, in a Phase 1 clinical trial. It is not approved for any indication and remains in clinical development.

What does Marlotamig target?

Marlotamig targets EGFR, a protein that is overexpressed or mutated in many solid tumors. By binding to EGFR, the drug is designed to interfere with signaling that drives tumor cell growth and survival. It is being studied in advanced solid tumors.

Who is developing Marlotamig?

Marlotamig is being developed by Regeneron Pharmaceuticals, Inc., which trades on the Nasdaq under the ticker REGN. Regeneron is running the clinical program evaluating Marlotamig in combination with cemiplimab in patients with advanced solid tumors.

What phase is Marlotamig in?

Marlotamig is in Phase 1 clinical development. It is an investigational drug and has not been approved by the FDA or any other regulatory agency. The Phase 1 program is evaluating its safety and activity in adults with advanced solid tumors.

What clinical trials is Marlotamig in?

Marlotamig is being studied in NCT04626635, a Phase 1 trial titled "A Trial to Find Out How Safe REGN7075 is and How Well it Works in Combination With Cemiplimab for Adult Participants With Advanced Cancers." The trial is active but not recruiting, with an enrollment of 548 participants across the United States, France, Israel, Netherlands, Poland, Spain, and Turkey.

Is Marlotamig the same as REGN7075?

Yes, Marlotamig is also known as REGN7075. REGN7075 is Regeneron's internal development code for the same investigational compound. Both names refer to the EGFR-targeted therapy being studied in Phase 1 for advanced solid tumors in combination with cemiplimab.
