Frequently asked questions about AGMB-129

What is AGMB-129 used for?

AGMB-129 is an investigational small molecule being developed for fibrostenotic Crohn's disease, a gastrointestinal condition. It has also been studied in healthy volunteers for pharmacokinetic and drug interaction purposes. The drug is currently in Phase 2 clinical development and is not yet approved by regulatory authorities.

Who makes AGMB-129?

AGMB-129 is being developed by AgomAb Therapeutics NV, a biopharmaceutical company. The company's ticker symbol is AGMB. AgomAb is conducting clinical trials to evaluate the safety, tolerability, pharmacokinetics, and pharmacodynamics of AGMB-129 in patients with fibrostenotic Crohn's disease.

What phase is AGMB-129 in?

AGMB-129 is in Phase 2 clinical development. The Phase 2 trial, known as STENOVA (NCT05843578), has been completed and evaluated the drug in patients with fibrostenotic Crohn's disease. The drug is investigational and has not been approved by the FDA or other regulatory agencies.

What clinical trials is AGMB-129 in?

AGMB-129 has been studied in four completed clinical trials. The Phase 2 STENOVA trial (NCT05843578) enrolled 103 patients with fibrostenotic Crohn's disease across multiple countries. Three Phase 1 trials were conducted in healthy volunteers: a drug-drug interaction study with midazolam (NCT05937386), a relative bioavailability and food effect study (NCT06397508), and a multiple ascending dose study (NCT07118878).

Is AGMB-129 the same as STENOVA?

No, AGMB-129 is the drug being studied, while STENOVA is the name of the Phase 2 clinical trial evaluating it. The STENOVA trial (NCT05843578) is a study of AGMB-129 in patients with fibrostenotic Crohn's disease. The drug itself is not known by any alternative names.
