Frequently asked questions about Calderasib OCT

What is Calderasib OCT?

Calderasib OCT is an investigational small molecule developed by Merck & Company, Inc. (ticker MRK). It is in Phase 1 clinical development. The therapeutic indication for Calderasib OCT has not been disclosed. It is also known as MK-1084.

Who makes Calderasib OCT?

Calderasib OCT is being developed by Merck & Company, Inc., which trades under the ticker MRK. Merck is the sponsor of the clinical program for this investigational small molecule.

What phase is Calderasib OCT in?

Calderasib OCT is in Phase 1 clinical development. It is an investigational drug and is not approved. One Phase 1 trial has been completed, and no trials are currently active.

What clinical trials is Calderasib OCT in?

Calderasib OCT has been studied in one completed Phase 1 trial, NCT06942741, titled a study to evaluate the effect of formulation and food on Calderasib (MK-1084) in healthy adult participants. That trial enrolled 52 healthy volunteers in the United States and was controlled and randomized.

Is Calderasib OCT the same as MK-1084?

Yes, Calderasib OCT is also known as MK-1084. The completed Phase 1 trial NCT06942741 refers to the drug as Calderasib (MK-1084), so both names identify the same investigational small molecule being developed by Merck & Company, Inc.
