The purpose of this study is to assess the bioequivalence (medicines that may have different names or be made in different ways, but have the same effect on the body) of different formulations of a CGRP receptor antagonist in healthy adult participants. The study is seeking participants who are: 1. Healthy males and females 18 years of age or older 2. Willing and able to comply with all scheduled visits, treatment plan, lifestyle considerations, and other study procedures. 3. Body Mass Index of 16-32 kilogram per meter squared (kg/m2); and a total body weight \>45 kg The study will help the team understand how difference in formulation may, or may not, affect how the medicine is absorbed, processed, and removed by the body.
Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.
Currently recruiting: the trial is enrolling patients. A data readout is not expected until after enrollment closes and the follow-up period is complete.
Pfizer Inc (PFE) is the sponsoring company for this trial. BiotechSign currently grades this company F (33/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
