The STAREE trial (a double-blind Australian primary-prevention trial in adults 70 and older) presented Saturday August 29, 2026 at ESC Congress 2026 Munich and simultaneously published in NEJM showed atorvastatin 40 mg daily reduced major cardiovascular events (cardiovascular death, nonfatal myocardial infarction, stroke, or coronary revascularization) by approximately 30% versus placebo over 5.9 years median follow-up in 9,971 participants (mean age 74.7, 52% women). The co-primary endpoint of disability-free survival (survival free of dementia and physical disability) did not reach statistical significance. Muscle, liver, and diabetes-related adverse events were more common on atorvastatin, though serious adverse events were balanced. STAREE addresses a long-standing evidence gap on statin efficacy in older adults without known cardiovascular disease, diabetes, or dementia. Not a peptide, but the trial matters for peptide-industry readers because it reframes the primary-prevention benefit-risk calculus that will need to be modeled for cardiovascular outcome trials of peptide obesity therapies in older populations.
US data-analytics firm nference published a real-world evidence analysis this week that compared frailty-related outcomes across three cohorts of US adults 65 and older: nearly 30,000 patients treated with Zepbound (tirzepatide) for obesity, nearly 19,000 receiving non-GLP-1 drugs for type 2 diabetes, and nearly 6,000 who underwent weight-loss surgery. Health records showed progressive declines in muscle mass and function developed in 0.16% of patients across the analysis, malnutrition in 1.6%, dehydration in 3%, and loss of appetite in 4.75%. Lead author Soundararajan's team focused on Zepbound because prior analyses linked tirzepatide with more weight and muscle loss than semaglutide (the active ingredient in Novo Nordisk's Wegovy and Ozempic). The authors said results should not discourage appropriate use of Zepbound or Wegovy in older adults and encouraged closer follow-up of older patients on GLP-1 therapy. The findings arrive as the Medicare GLP-1 Bridge (launched July 1, 2026) expands GLP-1 access to Part D beneficiaries and as prescribers weigh muscle-preservation strategies including selective androgen receptor modulators (SARMs) like Veru's enobosarm and myostatin inhibitors.
Prof. Luca Busetto (University of Padova) and colleagues will present at ECO 2026 a pooled subgroup analysis of 358 adults aged 65 and older (mean age 69, 72% women) drawn from STEP 1, 3, 4, 5, 8, and 9 — 248 received semaglutide 2.4 mg, 110 placebo. The semaglutide arm lost 15.4% body weight on average vs 5.1% on placebo; 46.8% of semaglutide users hit ≥15% weight loss vs 6.4% on placebo, and 28.6% reached ≥20% vs 2.7%. Waist circumference fell 14.3 cm vs 6.0 cm. 27% on semaglutide reached a healthy BMI (<27) vs 5.5%. Serious adverse events occurred in 19.0% on semaglutide vs 12.7% on placebo. The analysis complements Lilly's ECO 2026 orforglipron 65+ subgroup analysis from ATTAIN-1 and ATTAIN-2 — both filling the geriatric data gap for the first generation of mainstream obesity drugs.
A post-hoc subgroup analysis of Eli Lilly's orforglipron (Foundayo) in adults aged 65 and older, drawn from the ATTAIN-1 and ATTAIN-2 Phase 3 programs, will be presented at ECO 2026 in Istanbul May 12-15. The analysis pools 616 randomized participants (613 treated) — 118 on 6 mg, 135 on 12 mg, 146 on 36 mg orforglipron, and 214 placebo — across patients with and without type 2 diabetes. The geriatric data set addresses a long-standing clinical gap: incretin trials have systematically underenrolled adults over 65, the population most affected by obesity-related comorbidities and the most likely to face polypharmacy-related GI tolerability concerns. Lead author Dr. Deborah Horn (UTHealth Houston McGovern Medical School). The presentation is among the ECO 2026 abstracts that will shape geriatric prescribing patterns for the first FDA-approved GLP-1 pill that does not require fasting or water restrictions.
