Frequently asked questions about D961S

What is D961S used for?

D961S is an investigational small molecule being studied in a bioequivalence study. It was evaluated in a Phase 1 clinical trial to assess its bioequivalence compared with esomeprazole/buffered acetylsalicylic acid (ASA) in Japanese healthy male subjects. The drug is not approved and remains in clinical development.

Who makes D961S?

D961S is being developed by AstraZeneca PLC, a biopharmaceutical company listed on the stock exchange under the ticker AZN. The company sponsored a Phase 1 clinical trial of the drug in Japan.

What phase is D961S in?

D961S is in Phase 1 clinical development. It has completed one Phase 1 trial, which was a bioequivalence study. The drug is investigational and has not been approved by regulatory authorities.

What clinical trials is D961S in?

D961S has been studied in one completed Phase 1 clinical trial, identified as NCT01494402. The trial was titled 'Study to Assess the Bioequivalence Between D961S and Esomeprazole/Buffered Acetylsalicylic Acid (ASA) in Japanese Healthy Male Subjects' and enrolled 77 participants in Japan.

Is D961S the same as esomeprazole/buffered ASA?

No, D961S is not the same as esomeprazole/buffered acetylsalicylic acid (ASA). The Phase 1 clinical trial was designed to assess whether D961S is bioequivalent to the combination of esomeprazole and buffered ASA, meaning the study compared the two treatments to evaluate their similarity in the body.
