Frequently asked questions about AB102

What is AB102 used for?

AB102 is an investigational small molecule being studied in healthy volunteers. It is currently in Phase 1 clinical development, with a trial evaluating its safety, tolerability, and pharmacokinetics. AB102 is not approved for any indication and remains under investigation.

What does AB102 target?

AB102 targets MRGPRX2, a receptor involved in various physiological processes. By modulating this receptor, AB102 may have therapeutic potential, though its exact clinical application is still being explored in early-stage trials.

Who is developing AB102?

AB102 is being developed by Arcus Biosciences, Inc., a biopharmaceutical company traded on the NYSE under the ticker RCUS. The company is conducting a Phase 1 clinical trial to evaluate the drug's safety and pharmacokinetics in healthy participants.

What phase is AB102 in?

AB102 is in Phase 1 clinical development. The ongoing trial, NCT07662057, is recruiting participants to assess the drug's safety, tolerability, and pharmacokinetics. As an investigational agent, AB102 has not yet received regulatory approval.

What clinical trials is AB102 in?

AB102 is being studied in a single Phase 1 trial, NCT07662057, titled 'A Study to Investigate the Safety, Tolerability, and PK of AB102 in Healthy Participants.' This randomized, double-blind, placebo-controlled trial is recruiting 130 participants in the Netherlands.
