Failing to meet the primary endpoint in its confirmatory phase III Embark trial, Sarepta Therapeutics Inc.’s gene therapy, Elevidys (delandistrogene moxeparvovec), which received accelerated approval in June and was priced at $3.2 million, has one of three fates in its future, all of which are dependent on how the U.S. FDA perceives the data. Based on secondary endpoints showing statistical significance and a recent positive meeting with the agency, Sarepta could continue to market Elevidys under its current label for 4- and 5-year-old ambulatory Duchenne muscular dystrophy (DMD) patients; Sarepta is filing the postmarketing requirement needed to transition from accelerated to full approval.

The pivotal phase III study of brilaroxazine from Reviva Pharmaceuticals Holdings Inc. for adults with schizophrenia hit its primary endpoint and two key secondary endpoints, following positive phase II data in 2021.

Novartis AG’s radioligand therapy, Pluvicto, a bestseller for the company that has been restructuring itself, continues to show strong growth in the third quarter of 2023, according to its most recent financial results. Sales were up 217% from the same quarter in 2022 at $256 million. Analysts are predicting blockbuster sales. Adding to the momentum were new data from the phase III PSMAfore study of Pluvicto (lutetium [177Lu] vipivotide tetraxetan), in second-line cancer, hitting its primary endpoint of radiographic progression-free survival in treating prostate-specific membrane antigen-positive metastatic castration-resistant prostate cancer after treatment with androgen receptor pathway inhibitor therapy.
