Rhea-AI Summary
Regeneron Pharmaceuticals announced significant Phase 3 trial results for Libtayo (cemiplimab) in treating high-risk cutaneous squamous cell carcinoma (CSCC) post-surgery. The C-POST trial demonstrated remarkable efficacy, with Libtayo reducing disease recurrence or death risk by 68% compared to placebo. The drug showed 80% reduction in locoregional recurrence risk and 65% reduction in distant recurrence risk. After 24 months of follow-up, disease-free survival was 87% with Libtayo versus 64% with placebo. The safety profile was manageable, with 24% of Libtayo patients experiencing Grade ≥3 adverse events compared to 14% in the placebo group. Regulatory applications have been submitted in both the US and EU, positioning Libtayo as potentially the first immunotherapy to demonstrate significant benefit in high-risk CSCC in the adjuvant setting.

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.

Rhea-AI Summary
A federal court jury has ruled in favor of Regeneron Pharmaceuticals (NASDAQ: REGN) in an antitrust lawsuit against Amgen, finding that Amgen violated multiple antitrust and tort laws through anticompetitive bundling practices. The jury awarded Regeneron $135.6 million in compensatory damages and $271.2 million in punitive damages. The case centered on Amgen's use of cross-therapeutic bundled rebates, leveraging its drugs Enbrel and Otezla to force pharmacy benefit managers (PBMs) to exclusively select Repatha over Regeneron's Praluent in the PCSK9 category. This practice effectively blocked Praluent from competing fairly in the market, despite both drugs treating different conditions than Enbrel and Otezla. The verdict represents a significant victory for fair competition in the biotech industry and patient access to innovative therapies.
