Orforglipron (LY3502970), a novel, oral non‐peptide glucagon‐like peptide‐1 receptor agonist: A Phase 1b, multicentre, blinded, placebo‐controlled, randomized, multiple‐ascending‐dose study in people with type 2 diabetes

Aim: To report the results of a Phase 1b trial evaluating the safety, pharmacokinetics and pharmacodynamics of orforglipron (LY3502970), an oral, non‐peptide glucagon‐like peptide‐1 receptor agonist (GLP‐1RA), in patients with type 2 diabetes (T2D). Materials and Methods: This was a double‐blind, placebo‐controlled Phase 1 study evaluating five different dosing regimens. The first group established that weekly dose escalation of the daily doses of orforglipron was generally well tolerated. This enabled a parallel‐arm design for the four groups following. Participants were randomized 3:1 to daily doses of orforglipron or placebo for 12 weeks. Eligible participants with T2D were aged 18 to 70 years and had glycated haemoglobin (HbA1c) levels ≥53.0 mmol/mol (7.0%) and ≤91.3 mmol/mol (10.5%). Results: A total of 51 participants received orforglipron and 17 received placebo. In the placebo and orforglipron groups, respectively, baseline HbA1c was 8.1% and 8.0%, and baseline body weight was 90.3 and 88.4 kg. The most common adverse events were gastrointestinal‐related, and occurred early in treatment, similar to findings with other GLP‐1RAs. At Week 12, mean t1/2 ranged from 29 to 49 hours. Mean HbA1c change ranged from −1.5% to −1.8% across orforglipron doses, versus −0.4% with placebo, and body weight change was −0.24 to −5.8 kg across orforglipron doses, versus 0.5 kg with placebo. Conclusions: Orforglipron treatment resulted in meaningful reductions in HbA1c and body weight, with an adverse event profile consistent with that of other GLP‐1RAs. Orforglipron may provide a safe and effective once‐daily oral treatment alternative to injectable GLP‐1RAs or peptide oral formulations without water and food restrictions. [ABSTRACT FROM AUTHOR]
