Frequently asked questions about 14C-bleximenib

What is 14C-bleximenib used for?

14C-bleximenib is an investigational small molecule being studied for the treatment of Acute Lymphoblastic Leukemia. It is a radiolabeled form of the drug, currently in Phase 1 clinical development for this indication.

What does 14C-bleximenib target?

14C-bleximenib is a kinase inhibitor, as indicated by its '-nib' suffix. It is being studied in oncology, specifically for Acute Lymphoblastic Leukemia, though the specific kinase target has not been disclosed.

Who makes 14C-bleximenib?

14C-bleximenib is being developed by Johnson & Johnson, a company traded on the NYSE under the ticker JNJ. The drug is currently in Phase 1 clinical trials.

What phase is 14C-bleximenib in?

14C-bleximenib is in Phase 1 clinical development. It is an investigational drug, not yet approved by regulatory authorities, and is being studied in an early-stage clinical trial.

What clinical trials is 14C-bleximenib in?

14C-bleximenib is being studied in one active Phase 1 trial, NCT07295951, titled 'A Study of 14C-Bleximenib (Radiolabeled) in Participants With Acute Leukemia'. This trial is recruiting participants in the United Kingdom and has an enrollment target of 10.

Is 14C-bleximenib the same as bleximenib?

14C-bleximenib is a radiolabeled form of bleximenib, used in clinical studies to track the drug's absorption, distribution, metabolism, and excretion. The radiolabeled version is specifically used in early-phase trials to understand the drug's behavior in the body.
