Frequently asked questions about Mercaptopurine

What is Mercaptopurine?

Mercaptopurine is a small molecule drug candidate developed by Viatris Inc. (ticker: VTRS). It is being studied in Phase 1 clinical development. The specific medical conditions it is intended to treat have not been publicly disclosed, and its therapeutic area is classified as other.

What does Mercaptopurine target?

Mercaptopurine targets PPAT, also known as phosphoribosyl pyrophosphate amidotransferase. It acts as an inhibitor of this enzyme. PPAT is involved in purine biosynthesis, and inhibiting it interferes with that pathway. This mechanism defines Mercaptopurine as a small molecule inhibitor directed at PPAT.

Who makes Mercaptopurine?

Mercaptopurine is developed by Viatris Inc., which trades under the ticker symbol VTRS. Viatris is the company responsible for advancing this small molecule drug candidate through clinical development. The drug is currently in Phase 1 testing.

What phase is Mercaptopurine in?

Mercaptopurine is in Phase 1 clinical development. It is an investigational drug and is not approved. The Phase 1 program includes one completed trial with 60 enrolled participants. No active trials are currently listed for this candidate.

What clinical trials is Mercaptopurine in?

Mercaptopurine has been studied in one completed Phase 1 trial, NCT00648336, titled Fasting Study of Mercaptopurine 50 mg and Purinethol Tablets 50 mg. The trial enrolled 60 healthy male volunteers aged 18 years and older in the United States. It was randomized and active controlled, without double blinding.
