Frequently asked questions about OTX015/Birabresib

What is OTX015/Birabresib used for?

OTX015/Birabresib is an investigational small molecule being studied for the treatment of Acute Myeloid Leukemia. It is also being evaluated in other hematologic malignancies including Diffuse Large B-cell Lymphoma, Acute Lymphoblastic Leukemia, and Multiple Myeloma. The drug is in Phase 1 clinical development and is not yet approved.

What does OTX015/Birabresib target?

OTX015/Birabresib is a bromodomain (BRD) inhibitor. It targets bromodomain proteins, which are involved in regulating gene expression. By inhibiting these proteins, the drug aims to disrupt cancer cell growth and survival. This mechanism is being studied in the context of hematologic malignancies.

Who makes OTX015/Birabresib?

OTX015/Birabresib is being developed by Merck & Company, Inc., which trades under the ticker MRK. The drug is currently in Phase 1 clinical development as an investigational therapy for Acute Myeloid Leukemia and other hematologic malignancies.

What phase is OTX015/Birabresib in?

OTX015/Birabresib is in Phase 1 clinical development. It is an investigational drug and has not been approved by regulatory authorities. One Phase 1 trial has been completed, and the drug is no longer in active clinical trials according to available data.

What clinical trials is OTX015/Birabresib in?

OTX015/Birabresib has been studied in one clinical trial, identified as NCT01713582. This was a Phase 1 dose-finding study in hematologic malignancies, including Acute Myeloid Leukemia, Diffuse Large B-cell Lymphoma, Acute Lymphoblastic Leukemia, and Multiple Myeloma. The trial enrolled 141 participants and has been completed.

Is OTX015/Birabresib the same as MK-8628?

Yes, OTX015/Birabresib is also known as MK-8628. The clinical trial NCT01713582, titled 'A Dose-finding Study of the Bromodomain (Brd) Inhibitor OTX015/Birabresib (MK-8628) in Hematologic Malignancies,' uses both names to refer to the same drug.
