Abstract
- Aim: To evaluate the safety, tolerability, pharmacokinetics and pharmacodynamics of single and multiple doses of orforglipron (LY3502970), an oral, non‐peptide glucagon‐like peptide‐1 receptor agonist (GLP‐1RA) in healthy participants. Materials and Methods: This was a double‐blind, placebo‐controlled, Phase 1 study. Overtly healthy adults aged 18 to 65 years with body mass index of 20 to 40 kg/m2 and glycated haemoglobin concentration of 47.5 mmol/mol (<6.5%) were eligible. In Part A, participants received single‐dose orforglipron, with four cohorts receiving escalating doses (0.3‐6 mg). In Part B, participants received 4 weeks of daily repeated oral orforglipron with doses escalating weekly to four different final target doses (2‐24 mg). Results: Ninety‐two participants enrolled and received at least one study drug dose (32 in Part A [mean age 43.4 years] and 60 in Part B [mean age 42.5 years]). The most common adverse events were gastrointestinal tract‐related. Pharmacokinetics were approximately dose proportional, and the mean t1/2 was 24.6 to 35.3 hours after a single dose (0.3‐6 mg). On Day 28, the mean t1/2 was 48.1 to 67.5 hours across the dose range (2‐24 mg). Substantial reductions in body weight of up to 5.4 kg were observed after 4 weeks in orforglipron‐treated participants, compared to a reduction of 2.4 kg with placebo (P < 0.05). Orforglipron decreased fasting glucose levels across Days 1 to 28, and gastric emptying was delayed on Day 28. Conclusions: Orforglipron's long half‐life (25‐68 hours) allows once‐daily oral dosing, without water and food restrictions. Orforglipron had a pharmacodynamic and safety profile similar to that of injectable GLP‐1RAs, which supports continued clinical development. [ABSTRACT FROM AUTHOR]
