danuglipron immediate release (PF-06882961 IR) / Pfizer - LARVOL DELTA

Mechanism of CX11's QD vs. Danuglipron's BID via AI-PBPK Modeling (OBESITY WEEK 2025) - "Background: CX11 and Danuglipron, two small-molecule GLP-1 receptor agonists, share ​high structural similarity but exhibit ​divergent dosing regimens (CX11: once daily; Danuglipron: twice daily). In conclusion, CX11's favorable ​PK/PD profile—characterized by ​lower clearance and ​reduced tissue distribution—underpins its ​once-daily dosing and superior efficacy compared to Danuglipron. These insights highlight the critical role of ​structural optimization and ​tissue distribution control in advancing GLP-1 therapeutics with improved safety and dosing convenience."

Pfizer drops obesity pill development after liver injury report (Yahoo Finance) - P1 | N=82 | NCT06567327 | N=23 | NCT06568731 | Sponsor: Pfizer | "Pfizer has terminated the development of its oral obesity candidate danuglipron after a patient on a clinical trial with the drug suffered a liver injury...Two Phase I studies (NCT06567327 and NCT06568731) met pharmacokinetic (PK) endpoints and determined a formulation and dose for danuglipron. In one of these studies, an asymptomatic patient experienced a potential drug-induced liver injury. The injury resolved after drug discontinuation; however, Pfizer has decided, based on this event, available clinical data, and recent input from regulators to discontinue the development of the drug. The therapy has been investigated in a total of 1,400 patients."

Pfizer Announces Topline Phase 2b Results of Oral GLP-1R Agonist, Danuglipron, in Adults with Obesity (Businesswire) - P2b | N=630 | NCT04707313 | Sponsor: Pfizer | "Pfizer Inc...today announced topline data from the Phase 2b clinical trial (NCT04707313) investigating...danuglipron (PF-06882961), in adults with obesity and without type 2 diabetes. The study met its primary endpoint demonstrating statistically significant change in body weight from baseline. Twice-daily dosing of danuglipron showed statistically significant reductions from baseline in body weight for all doses, with mean reductions ranging from -6.9% to -11.7%, compared to +1.4% for placebo at 32 weeks, and -4.8% to -9.4%, compared to +0.17% for placebo at 26 weeks. Placebo-adjusted reductions in mean body weight ranged from -8% to -13% at 32 weeks and -5% to -9.5% at 26 weeks....Future development of danuglipron will be focused on a once-daily formulation, with pharmacokinetic data anticipated in the first half of 2024."

Safety and efficacy of the new, oral, small-molecule, GLP-1 receptor agonists orforglipron and danuglipron for the treatment of type 2 diabetes and obesity: systematic review and meta-analysis of randomized controlled trials. (PubMed, Metabolism) - "Preliminary evidence supports that orforglipron and danuglipron are efficient in glycemic control and weight reduction in T2DM, obesity or both. More longitudinal research is warranted in order to provide deeper insights into their efficacy, safety and tolerability before their potential incorporation in the pharmacological arsenal against T2DM or obesity."

Newer Pharmacological Interventions Directed at Gut Hormones for Obesity. (PubMed, Br J Pharmacol) - "There are several approved single or dual incretin agonists which are administered subcutaneously daily (e.g., liraglutide) or weekly (e.g., semaglutide, dulaglutide, and exenatide QW), and experimental dual or triple incretin agonists...Oral semaglutide (administered daily) is approved for type 2 diabetes and is on track for regulatory review for obesity...In the future, it is anticipated that small molecule GLP-1 receptor agonists (e.g., oral danuglipron) will be developed. These pharmacological agents are having significant impact on glycemic control and obesity and their co-morbidities."
