Regeneron Pharmaceuticals Stock Price, News & Analysis

Regeneron Pharmaceuticals (NASDAQ: REGN) reported promising results from the Phase 1/2 CHORD trial of DB-OTO, a gene therapy for profound genetic hearing loss caused by otoferlin gene variants. Of 12 treated children, 10 out of 11 with post-treatment assessments showed notable hearing improvements.

The first child treated, at 10 months old, showed near-normal hearing levels across key speech frequencies at 48 weeks, with continued progress at 72 weeks, including the ability to identify words at conversational levels. Among five participants with 24-week assessments, three achieved 'nearly normal' or normal hearing levels.

The treatment was well-tolerated across all participants, with only temporary post-surgical vestibular effects in five patients that resolved within 6 days. DB-OTO has received multiple FDA designations including Orphan Drug, Rare Pediatric Disease, Fast Track, and Regenerative Medicine Advanced Therapy, as well as EMA Orphan Drug Designation.

Regeneron Pharmaceuticals (NASDAQ: REGN) announced the FDA's acceptance of their resubmitted Biologics License Application (BLA) for linvoseltamab, targeting the treatment of adult patients with relapsed/refractory multiple myeloma. The treatment is specifically for patients who have undergone at least four prior therapy lines or those with three prior lines who are refractory to their last treatment.

The FDA's decision is expected by July 10, 2025. The resubmission follows the resolution of third-party fill/finish manufacturing issues, which was previously the only approvability concern. The application is supported by data from the LINKER-MM1 trial and is currently also under review by the European Medicines Agency (EMA) for the same patient population.

Regeneron Pharmaceuticals (REGN) presented positive Phase 3 QUASAR trial results for EYLEA HD® (aflibercept) Injection 8 mg in treating macular edema following retinal vein occlusion (RVO). The trial met its primary endpoint, demonstrating that EYLEA HD patients dosed every 8 weeks achieved non-inferior vision gains compared to EYLEA® 2 mg dosed every 4 weeks.

Key findings show that 88% of patients maintained an 8-week dosing schedule after 3 initial monthly doses, and 93% after 5 initial monthly doses. The safety profile remained consistent with previous trials, with ocular pressure increase reported in 5% of patients. The data will support a supplemental Biologics License Application to the FDA in Q1 2025.

Regeneron Pharmaceuticals (NASDAQ: REGN) announced positive three-year results for EYLEA HD® (aflibercept) Injection 8 mg in wet age-related macular degeneration (wAMD) patients from the Phase 3 PULSAR trial extension study.

Patients who switched from EYLEA® 2 mg to EYLEA HD also maintained improvements with extended dosing intervals: 79% achieved ≥3 months and 43% achieved ≥4 months intervals.

The safety profile remained consistent with previous trials, with ocular treatment emergent adverse events including cataract, retinal hemorrhage, and reduced visual acuity. The intraocular inflammation rate was 2.4% for patients switching from EYLEA to EYLEA HD and 1.9% for patients starting with EYLEA HD.
