Frequently asked questions about RTA 901, 10 or

What is RTA 901?

RTA 901 is an investigational small molecule developed by Biogen Inc. (ticker BIIB). It has been studied in healthy adult volunteers rather than in patients with a specific disease. The program is in Phase 1 clinical development, and the compound is also referred to as RTA 901 Capsules, 10 or 40 mg.

What is RTA 901 used for?

RTA 901 has been studied in healthy adult participants, not in a patient population with a named disease. Its single clinical trial enrolled healthy volunteers to assess safety, tolerability, and pharmacokinetics. No approved therapeutic indication for RTA 901 is established, and the asset remains in early-stage clinical development.

Who makes RTA 901?

RTA 901 is developed by Biogen Inc., which trades under the ticker BIIB. Biogen is the sponsor of the compound's clinical program. The drug is a small molecule and is also identified as RTA 901 Capsules, 10 or 40 mg in study documentation.

What phase is RTA 901 in?

RTA 901 is in Phase 1 clinical development. Its only recorded trial was a Phase 1 study in healthy adults, and that trial is now completed. Because the program has not advanced beyond Phase 1, RTA 901 is investigational and has not been approved by the FDA for any indication.

What clinical trials is RTA 901 in?

RTA 901 has been evaluated in one clinical trial, NCT02666963, titled a study of the safety, tolerability, and pharmacokinetics of single and multiple doses of RTA 901 in healthy adults. That Phase 1 trial was randomized, double-blind, and controlled, enrolled 78 participants in the United States, and is completed.
