What Does the ATTAIN-1 Phase 3 Trial Reveal About Oral Orforglipron's 72-Week Weight Loss and Predicted Cardiometabolic Risk Reduction at 5.5 mg, 9 mg, and 17.2 mg in 2026?

The ATTAIN-1 Phase 3 trial (Wharton et al., NEJM 2025) showed once-daily oral orforglipron produced dose-dependent mean body-weight reductions at all three approved maintenance doses versus placebo at 72 weeks. Post-hoc modelling linked the highest approved dose to a predicted 57% reduction in 10-year type 2 diabetes risk and an 18% reduction in predicted cardiovascular disease risk versus placebo.

Does Semaglutide or Tirzepatide Increase the Risk of NAION — and What Is the Absolute Excess Risk Over 18 Months in 2026?

Current evidence indicates that semaglutide is associated with a statistically significant increase in the risk of nonarteritic anterior ischemic optic neuropathy (NAION), particularly in patients with type 2 diabetes or obesity. The absolute excess risk is approximately 3–4 additional cases per 10,000 treated patients over 18 months. Tirzepatide carries a similar signal. Causality has not been established.

What Does the 2026 Sever & Sikiric Narrative Review Reveal About BPC-157 as a Cytoprotective Liver Therapy — and How Does It Compare to Standard Hepatoprotective Agents?

The 2026 narrative review by Sever, Sikiric, and colleagues in Pharmaceuticals (MDPI, 19(10):1559) positions stable gastric pentadecapeptide BPC 157 as a prototype cytoprotective agent for liver injury. Across rodent models of paracetamol toxicity, alcohol damage, CCl4 exposure, and ischemia-reperfusion, BPC 157 attenuated hepatocyte injury, reduced oxidative stress markers, and preserved endothelial integrity — matching or outperforming standard hepatoprotective agents.

Does Olatorepatide's Dual-Biased GLP-1/GIP Mechanism Explain the 19.3% Weight Loss and Low Adverse-Event Rate Seen in the 2026 LIGHTEN Phase III Trial?

The LIGHTEN Phase III trial reported 19.3% mean body-weight reduction at 48 weeks with olatorepatide 15 mg weekly in 604 Chinese adults. Investigators attribute this to olatorepatide's dual-biased receptor pharmacology, which preferentially amplifies cAMP signalling over beta-arrestin recruitment at both GLP-1R and GIPR, producing strong efficacy with a nausea rate of only 7.8% and zero GI-related discontinuations.

What Does the 2026 First-in-Human Phase I Trial of GZC8072 Reveal About the Safety, Pharmacokinetics, and Weight-Loss Potential of a Once-Weekly Oral GLP-1 Agonist?

The 2026 first-in-human Phase I trial of GZC8072 — a once-weekly oral peptide GLP-1 receptor agonist by Gan & Lee Pharmaceuticals — is designed to answer precisely this question. The 112-participant SAD/MAD study evaluates safety, tolerability, pharmacokinetics, and pharmacodynamics in healthy adults and people with overweight or obesity. No efficacy data have been reported; the trial is actively enrolling.

What Does the 2026 Yuan IJMS Review Reveal About BPC-157's Shared Molecular Architecture Across Tissue Repair and Pain Management?

The 2026 Yuan review in IJMS (27:2876) establishes that BPC-157's repair and analgesic effects are convergent, not parallel. The VEGFR2–Akt–eNOS axis drives both angiogenesis and nitric oxide–mediated analgesia; cytokine suppression limits tissue damage and nociceptor sensitisation simultaneously; FAK–paxillin coordinates fibroblast repair. Three shared signalling nodes explain the compound's dual pharmacology from a single 15-amino-acid sequence.

Safety First

Every protocol article on Peptides Plus includes a structured safety section covering known adverse effects, contraindications, and evidence gaps. We treat incomplete evidence as information, not an excuse to omit warnings.

Where no controlled human safety data exists, that is stated explicitly. Where contraindications are documented, they are presented before dosing information, not after it. The deliberate, consistent placement of safety information is part of what makes this site useful — and what makes it responsibly citable.
