Clinical trial coverage on Peptide News Digest pulls in Phase 1 through Phase 3 readouts across the peptide universe — GLP-1 obesity and cardiometabolic trials (SELECT, SURMOUNT-4, ACHIEVE-3, REDEFINE-1, SYNCHRONIZE-1), peptide vaccine work (AMPLIFY-201, MEL39), peptide-drug conjugate trials, and antimicrobial peptide programs.
Most of the noise sits with Lilly and Novo, but the interesting reads are usually elsewhere: Bicycle Therapeutics on solid tumors, Lirum on Ewing sarcoma, Cerapedics on lumbar fusion, Pelage on hair loss. Real-world evidence and registry data also land here when they reframe what the randomized trials showed.
Each entry names the sponsor, the phase, and the endpoint. Browse the latest below, or jump to the readouts by drug at #semaglutide, #tirzepatide, or #orforglipron.
New ORION study results show oral semaglutide produced greater weight loss and better tolerability than rival orforglipron (Foundayo). Novo also introduced higher-dose Wegovy with aggressive discounts.
Merck's investigational oral macrocyclic peptide PCSK9 inhibitor demonstrated significantly greater LDL-C reductions at 8 weeks vs guideline-recommended oral non-statin therapies, delivering injectable-level cholesterol lowering in pill form.
MetaVia dosed the first patient in a higher-dose Phase 1 study of DA-1726, its GLP-1 and glucagon dual agonist for obesity treatment, marking continued advancement in next-gen weight loss drugs.
UC launched a clinical trial using Peptilogics' peptide-based antimicrobial agent to treat prosthetic joint infections by targeting bacterial biofilms that have resisted traditional therapies.
An indirect comparison found oral semaglutide may produce greater weight loss than orforglipron, though head-to-head T2D data showed orforglipron had greater HbA1c reductions vs lower-dose oral semaglutide. Lack of CV outcomes data for orforglipron remains a key limitation.
The FLOW trial showed semaglutide reduced major kidney events by 24%, and retatrutide demonstrated up to 28.7% weight loss in TRIUMPH-4. The full pipeline including CagriSema, MariTide, and survodutide was presented.
Retatrutide met its primary endpoint of superior A1C reduction and all key secondary endpoints at 40 weeks compared with placebo in type 2 diabetes patients, also demonstrating significant weight loss.
The ACHIEVE-3 trial in The Lancet showed Eli Lilly's Foundayo (orforglipron) superior on HbA1c, while Novo Nordisk's oral Wegovy may have an edge in weight-loss efficacy.
Novo Nordisk's long-acting amylin analog produced significant weight loss as standalone treatment in a 68-week double-blind trial, strengthening its profile ahead of the CagriSema FDA decision.
Phase IIIb results show investigational 7.2 mg semaglutide dose produced 21% mean weight loss in adults with obesity without diabetes, with a tolerable safety profile.
The 25-mg oral semaglutide formulation broadens GLP-1 access for chronic weight management, with pharmacists playing a key role in patient counseling and adherence support.
Orforglipron (Foundayo) is the first GLP-1 pill that can be taken at any time without food or water restrictions, a major differentiator from oral semaglutide which requires morning dosing on an empty stomach.
Eli Lilly's triple agonist (GIP/GLP-1/glucagon) retatrutide met its primary A1C reduction endpoint and all key secondary endpoints at 40 weeks in the TRANSCEND-T2D-1 trial.
Managed Healthcare Executive compares Foundayo (orforglipron) vs oral Wegovy (semaglutide). ACHIEVE-3 trial data showed Foundayo superior on HbA1c, but oral Wegovy may edge ahead on weight loss.
Eli Lilly's triple GLP-1/GIP/glucagon receptor agonist retatrutide demonstrated up to 28.7% weight loss along with significant knee pain reductions in obesity patients with osteoarthritis. Seven additional Phase 3 trials expected to report throughout 2026.
The ATTAIN-MAINTAIN trial demonstrated that patients switching from injectable semaglutide or tirzepatide to oral orforglipron maintained their weight loss.
At APhA2026, semaglutide's FLOW trial showed 24% reduction in major kidney events in CKD patients, while tirzepatide's SURMOUNT-OSA trial demonstrated dramatic reductions in sleep apnea severity.
Eli Lilly's oral GLP-1 drug orforglipron is among the most consequential FDA decisions in Q2 2026. Analysts expect it to help Lilly's tirzepatide franchise exceed $100 billion in peak revenue.
