Frequently asked questions about RPT193

What is RPT193 used for?

RPT193 is an investigational small molecule being developed for the treatment of atopic dermatitis, a chronic inflammatory skin condition. It is in Phase 1 clinical development and has not been approved for any indication. RAPT Therapeutics, Inc. is the developer.

What does RPT193 target?

RPT193 targets CCR4, a chemokine receptor. By binding to CCR4, the drug is designed to modulate immune cell trafficking, which may reduce inflammation associated with atopic dermatitis. This mechanism is being evaluated in clinical trials.

Who is developing RPT193?

RPT193 is being developed by RAPT Therapeutics, Inc., a biopharmaceutical company. The company's ticker symbol is RAPT. RAPT Therapeutics is focused on discovering and developing oral small molecule therapies for inflammatory diseases and oncology.

What phase is RPT193 in?

RPT193 is in Phase 1 clinical development. It has completed one Phase 1 trial and is not currently in active trials. The drug remains investigational and has not been approved by the FDA or any regulatory agency.

What clinical trials is RPT193 in?

RPT193 has been evaluated in a single Phase 1 trial, NCT04271514, titled 'A First-in-Human Study of RPT193 in Healthy Volunteers and Patients With Atopic Dermatitis.' The trial was completed and enrolled 103 participants across the United States and the Netherlands.

Is RPT193 approved by the FDA?

No, RPT193 is not approved by the FDA. It is an investigational drug in Phase 1 clinical development for atopic dermatitis. Approval would require successful completion of later-stage trials and regulatory review.
