Frequently asked questions about 14C-aticaprant

What is 14C-aticaprant?

14C-aticaprant is an investigational small molecule being developed by Johnson & Johnson (JNJ). It is a radiolabeled form of aticaprant, used in clinical research to study the drug's absorption, distribution, metabolism, and excretion in the body. It is currently in Phase 1 clinical development.

What is 14C-aticaprant used for?

14C-aticaprant is used in clinical research to study the pharmacokinetics of aticaprant in healthy adult male participants. It is not intended for therapeutic use; rather, it serves as a research tool to understand how the body processes the drug. The study is conducted in healthy volunteers.

Who makes 14C-aticaprant?

14C-aticaprant is developed by Johnson & Johnson, a multinational pharmaceutical company traded on the New York Stock Exchange under the ticker JNJ. The company is conducting clinical trials to evaluate the drug's properties in healthy participants.

What phase is 14C-aticaprant in?

14C-aticaprant is in Phase 1 clinical development. It is an investigational drug, meaning it has not been approved by regulatory authorities and is still undergoing clinical trials to assess its safety and pharmacokinetic profile in humans.

What clinical trials is 14C-aticaprant in?

14C-aticaprant has one completed clinical trial, identified as NCT05197062, titled 'A Study of 14C JNJ-67953964 in Healthy Adult Male Participants.' This Phase 1 study enrolled 8 healthy male participants in the Netherlands and was completed. The trial was uncontrolled and not randomized or double-blinded.

Is 14C-aticaprant the same as aticaprant?

14C-aticaprant is a radiolabeled version of aticaprant, where the carbon-14 isotope is incorporated into the molecule. This labeling allows researchers to track the drug's movement and metabolism in the body. It is used specifically for pharmacokinetic studies in healthy volunteers.
