Rhea-AI Summary
Regeneron and Sanofi presented groundbreaking results from the EVEREST Phase 4 trial comparing Dupixent to Xolair in treating chronic rhinosinusitis with nasal polyps (CRSwNP) and coexisting asthma.

Key achievements include a 1.60-point greater reduction in nasal polyp size and an 8.0-point superior improvement in smell identification compared to Xolair. Dupixent also showed significant advantages in nasal congestion reduction, symptom severity, and quality of life measures. In asthma-related outcomes, Dupixent demonstrated a 150 mL improvement in lung function and better asthma control. The safety profiles were comparable, with adverse events reported in 64% of Dupixent patients versus 67% for Xolair, and serious adverse events at 2% and 4% respectively.

Interim Results from Ongoing Phase 2 COURAGE Trial Confirm Potential to Improve the Quality of Semaglutide (GLP-1 receptor agonist)-induced Weight Loss by Preserving Lean Mass

Rhea-AI Summary
Regeneron Pharmaceuticals (REGN) reported interim Phase 2 COURAGE trial results evaluating combinations of semaglutide with muscle-preserving antibodies for obesity treatment. The study revealed that 35% of semaglutide-induced weight loss came from lean mass loss. When combined with trevogrumab (with/without garetosmab), the treatment preserved 50-80% of lean mass while enhancing fat loss compared to semaglutide alone. The triplet combination (semaglutide + trevogrumab + garetosmab) showed the highest fat loss (-25.4 lbs) and total weight loss (-30.0 lbs) but had significant safety concerns with a 28.3% discontinuation rate. The dual combination of semaglutide with trevogrumab demonstrated better tolerability while still providing meaningful lean mass preservation and enhanced fat loss. The trial's complete data will be available later in 2025.

Itepekimab Met Primary Endpoint in One of Two Chronic Obstructive Pulmonary Disease (COPD) Phase 3 Trials

Rhea-AI Summary
Regeneron and Sanofi announced mixed results from two Phase 3 trials (AERIFY-1 and AERIFY-2) evaluating itepekimab for COPD in former smokers. AERIFY-1 met its primary endpoint, showing a significant 27% reduction in moderate/severe exacerbations compared to placebo at week 52. However, AERIFY-2 failed to meet the same endpoint, despite showing early benefits. The trials tested two dosing regimens (every two weeks and four weeks) added to standard therapy. Safety profiles were consistent with previous trials, with comparable adverse events between treatment and placebo groups. Both companies are reviewing the data and will discuss next steps with regulatory authorities. The trials were affected by lower-than-expected exacerbation rates, possibly due to the COVID-19 pandemic impact on enrollment.
