Frequently asked questions about BMS-986521

What is BMS-986521 used for?

BMS-986521 is an investigational small molecule being studied in healthy volunteers. It is currently in Phase 1 clinical development, with an ongoing positron emission tomography study assessing its occupancy of M4 muscarinic acetylcholine receptors in healthy adult participants.

What does BMS-986521 target?

BMS-986521 targets the M4 muscarinic acetylcholine receptor. A Phase 1 positron emission tomography study is evaluating the occupancy of these receptors by BMS-986521 in healthy adult participants, which helps determine how well the drug binds to its target in the brain.

Who makes BMS-986521?

BMS-986521 is being developed by Bristol-Myers Squibb Company, traded on the New York Stock Exchange under the ticker BMY. The company is conducting a Phase 1 clinical trial of this investigational small molecule in healthy volunteers.

What phase is BMS-986521 in?

BMS-986521 is in Phase 1 clinical development. It is an investigational drug, not yet approved, and is currently being studied in a recruiting Phase 1 trial in healthy volunteers. The trial is designed to assess receptor occupancy using positron emission tomography.

What clinical trials is BMS-986521 in?

BMS-986521 is being studied in one active Phase 1 clinical trial, NCT07655518. This trial is a positron emission tomography study to assess the occupancy of M4 muscarinic acetylcholine receptors by BMS-986521 in healthy adult participants. The study is recruiting in Belgium with an enrollment of 12 participants.

Is BMS-986521 the same as any other drug?

No alternative names for BMS-986521 have been disclosed. The drug is identified solely by its compound code BMS-986521 in clinical trial records, and no other names or aliases are associated with it in the available information.
