Arecor Therapeutics announced the initiation of a Ph1 clamp study comparing its ultra-rapid insulin (AT247) to Novolog and Fiasp in T1DM patients (view CT.gov record). Recall, at EASD 2020, Arecor presented an abstract (view here) for a Ph1 study which demonstrated AT247 had a faster onset of glucose-lowering than aspart (17 vs. 50 minutes) and a greater early glucose-lowering effect compared to both aspart and faster aspart (previous FENIX insight). Below FENIX provides brief thoughts on the initiation of the Ph1 trial and Arecor’s diabetes pipeline.
