Regeneron Pharmaceuticals and Sanofi announced the FDA's approval of Dupixent (dupilumab) for treating prurigo nodularis in adults, marking it as the first approved therapy for this chronic skin condition. This decision impacts about 75,000 adults in the U.S. affected by prurigo nodularis, a disease characterized by severe itching and skin lesions. The approval followed positive outcomes from pivotal Phase 3 trials, where Dupixent demonstrated significant reductions in itch and skin lesions compared to placebo. Safety data were consistent with known profiles, with common adverse events including nasopharyngitis and conjunctivitis.

Intellia Therapeutics and Regeneron Pharmaceuticals announced promising interim results from the Phase 1 study of NTLA-2001, a CRISPR therapy for transthyretin (ATTR) amyloidosis. The trial exhibited significant mean serum transthyretin reductions of 93% and 92% at doses of 0.7 mg/kg and 1.0 mg/kg, respectively, on day 28. The treatment was well-tolerated, with minimal adverse reactions. Follow-ups indicated sustained reductions over two to six months. Intellia plans to expand the study with a fixed dose of 0.7 mg/kg and aims for a pivotal trial, potentially including U.S. patients.

Regeneron Pharmaceuticals and Sanofi announced the publication of significant Phase 3 trial results for Dupixent (dupilumab) in treating children aged 6 months to 5 years with uncontrolled atopic dermatitis. The study demonstrated that Dupixent, in combination with low-potency topical corticosteroids, improved skin clearance, reduced severity of disease, and lessened itch compared to placebo. Safety profiles were consistent with older children. The FDA approved Dupixent for this age group in June 2022, with further regulatory reviews ongoing in Europe.

Regeneron (REGN) and Alnylam (ALNY) announced positive preliminary data from a Phase 1 study of ALN-HSD, aimed at treating nonalcoholic steatohepatitis (NASH). Results show robust target knockdown and lower liver enzymes in patients receiving ALN-HSD compared to placebo, with a favorable safety profile. The companies plan to advance to a Phase 2 trial in late 2022. The study highlighted a significant unmet need in NASH, which affects 16 million people in the U.S. and is projected to be a leading cause of liver transplants.

Alnylam and Regeneron have released preliminary Phase 1 results for ALN-HSD, an RNAi therapeutic targeting HSD17B13, aimed at treating nonalcoholic steatohepatitis (NASH).

The study showed promising outcomes, with robust target knockdown and reduced liver enzymes over six months in 20 patients compared to 4 in the placebo group.

Following this success, a Phase 2 study is set to commence in late 2022. Safety data indicated mild injection site reactions, with no serious adverse events reported, further validating ALN-HSD's potential in addressing NASH's significant unmet medical needs.

Positive clinical data from a Phase 2 trial of Libtayo (cemiplimab) show a 63.3% combined pathologic response rate in patients with stage II to IV resectable cutaneous squamous cell carcinoma (CSCC). The trial involved 79 patients, with a 68% objective response rate. The findings were presented at the ESMO Congress 2022 and published in the New England Journal of Medicine. Adverse events were reported in 87% of patients; however, serious events were only 17%. Follow-up studies are ongoing, assessing potential impacts on disease-free survival.

Regeneron Pharmaceuticals (NASDAQ: REGN) presented positive clinical data for its investigational LAG-3 inhibitor fianlimab combined with PD-1 inhibitor Libtayo at the ESMO Congress 2022 in Paris. The results from a Phase 1 trial indicated an overall response rate (ORR) exceeding 60% in two independent cohorts of PD-1/PD-L1-naïve patients. The combination's safety profile was similar to Libtayo monotherapy, with a significant majority of patients experiencing adverse events. A Phase 3 trial is currently enrolling patients to further evaluate this promising combination in advanced melanoma.

Regeneron Pharmaceuticals (NASDAQ: REGN) presented promising Phase 1 data for two bispecific antibodies at the ESMO Congress 2022. The first is ubamatamab (REGN4018), targeting recurrent ovarian cancer, showcasing a 14% overall response rate in treated patients. The disease control rate stood at 57%. The second, REGN5093, aimed at MET-altered non-small cell lung cancer (NSCLC), reported a 17% partial response rate among the highest dose cohort. Both agents exhibited manageable safety profiles, prompting further clinical investigations.
