Regeneron Pharmaceuticals Inc. and Tessera Therapeutics Inc. have established a global collaboration to develop and commercialize TSRA-196, Tessera’s lead investigational in vivo gene editing program for the treatment of α-1 antitrypsin deficiency (AATD).

The BioWorld Biopharmaceutical Index extended its rebound through August and September, closing the third quarter (Q3) slightly in positive territory after losing ground earlier in the year.

With a modest $7 million up front but an ultimate payout potentially topping $1 billion on the line, Modex Therapeutics Inc. will collaborate with Regeneron Pharmaceuticals Inc. to find and develop multispecific antibodies for treating multiple indications.

The U.S. FDA named the first nine recipients of the recently unveiled commissioner’s national priority voucher (CNPV) program aimed at addressing unmet public health needs by shortening regulatory review times to as little as one to two months. For one of those firms, Disc Medicine Inc., which submitted an NDA for bitopertin for rare genetic disorder erythropoietic protoporphyria in September, that could mean a potential approval before the end of 2025.

Patients with chronic spontaneous urticaria who remain symptomatic despite H1 antihistamine treatment now have a new oral treatment option, with the U.S. FDA’s approval of Novartis AG’s Rhapsido (remibrutinib), a Bruton’s tyrosine kinase inhibitor administered by pill twice daily.

“People have some inability to focus on [Regeneron Pharmaceuticals Inc.’s] pipeline,” which stands as “the most prolific in the industry, I would dare to say,” CEO Leonard Schleifer remarked during the Morgan Stanley health care conference Sept. 8. Most recently, Regeneron bragged on two prospects. The ultra-rare disease fibrodysplasia ossificans progressiva (FOP) took center stage Sept. 17 with news that the phase III Optima trial testing fully human monoclonal antibody garetosmab met its primary endpoint. Separately, Regeneron provided updated analyses of the phase II Courage trial that tested new pairings of GLP-1 receptor agonist semaglutide plus the anti-GDF8/anti-myostatin compound trevogrumab, with or without garetosmab, in obesity.

Phase III results from Sanofi SA’s study of amlitelimab in treating atopic dermatitis met the primary and key secondary endpoints, but investors took a step back.

Amid the increasingly competitive myasthenia gravis drug development space, siRNA candidate cemdisiran met phase III endpoints, with the monotherapy showing numerically higher results than a combination product. Regeneron Pharmaceuticals Inc., which has a worldwide license to cemdisiran from Alnylam Pharmaceuticals Inc., plans to file for U.S. approval in generalized myasthenia gravis, a rare and chronic autoimmune disease leading to life-threatening muscle weakness, in the first quarter of 2026.
