A failed July inspection of manufacturer Catalent Indiana LLC has delayed another U.S. FDA approval, the latest being that of Scholar Rock Inc.’s selective anti-latent myostatin antibody, apitegromab, which was expected to become the first therapy to enhance skeletal muscle in patients with spinal muscular atrophy.

“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.

As Avidity Biosciences Inc. brought the second-largest follow-on offering of the year to the market, the company also released positive early and midstage stage results of del-zota, an antibody-oligonucleotide conjugate, in treating Duchenne muscular dystrophy. Phase I/II results showed a reversal of disease progression in patients who have been continuously treated for a year, plus improvements in several functional measures.

“New explosions in biotechnology are allowing us to interrogate cancers at a very sophisticated level compared to before,” Dennis Slamon told audience members at the Global Bio Conference in Seoul, South Korea Sept. 3.

Following a May phase II readout and a recent presentation of Tourmaline Bio Inc.’s long-acting anti-IL-6 IgG2 monoclonal antibody, pacibekitug, for atherosclerotic cardiovascular disease (ASCVD), Novartis AG offered $1.4 billion, or $48 per share, to buy the barely 4-year-old company. Previously shelved by Pfizer Inc., which had been developing it for autoimmune disorders, pacibekitug fell into the hands of New York-based Tourmaline through a May 2022 license agreement. In addition to the Tranquility phase II trial in ASCVD, the company’s lead product is also in the phase IIb Spirited trial for thyroid eye disease, a readout for which is expected in early 2026.

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.

Roivant Sciences Ltd.’s Immunovant Inc. unit unveiled phase II data in Graves’ disease with batoclimab, whetting appetites on Wall Street for the results with next-generation prospect IMVT-1402 from two potentially registrational trials that are enrolling now.

Oddsmakers placing their bets on which drugs will be in play for round 3 of the U.S. Inflation Reduction Act (IRA) price negotiations are doing some reshuffling, thanks to an orphan drug provision tucked into the Trump administration’s One Big Beautiful Bill Act (OBBBA) that was signed into law on the Fourth of July.

Bio-Thera Solutions Inc. announced Aug. 26 that the European Commission cleared Usymro (BAT-2206) as a biosimilar to Janssen Pharmaceuticals Inc.’s Stelara (ustekinumab). The EMA issued marketing authorization for Usymro on Aug. 14, following the EMA’s Committee for Medicinal Products for Human Use adopting a positive opinion on June 19.
