FDA rejects PTC’s Friedreich’s ataxia drug, for now

Aug. 19, 2025
By Jennifer Boggs
No Comments

The U.S. FDA asked for another “adequate and well-controlled study” in the complete response letter (CRL) issued to PTC Therapeutics Inc. for 15-lipoxygenase inhibitor vatiquinone. The agency said “substantial evidence of efficacy was not demonstrated.”

Aug. 18, 2025
By Mari Serebrov
No Comments
A U.S. appeals court schooled the FDA as it handed Vanda Pharmaceuticals Inc. a “technical knockout” of sorts in yet another regulatory bout with the agency – this one over the FDA’s refusal to grant the company’s request for a hearing after it had received a complete response letter (CRL) for a jet lag supplemental indication for Hetlioz (tasimelteon).

Aug. 13, 2025
By Lee Landenberger
No Comments
Taking weight off with a glucagon-like peptide-1 (GLP-1) receptor agonist and keeping it off once the drug has been discontinued has been a tall order but Response Pharmaceuticals Inc. is seeing progress. Top-line results from its randomized, double-blind, placebo-controlled, parallel-group phase II study of RDX-002, in those who had already wrapped up a GLP-1 receptor agonist course for reducing obesity, were positive.

Brinsupri dose choice means bronchiectasis upside, Insmed says

Aug. 12, 2025
By Randy Osborne
Insmed Inc. CEO William Lewis said that offering two doses of Brinsupri (brensocatib) will complicate payer coverage “not at all, just the opposite. It’s going to give the flexibility to physicians to choose how they want to engage with their patients, wrestle with whatever issues may be in their minds related to safety [and] what have you.” The U.S. FDA approved Insmed’s first-in-class dipeptidyl peptidase 1 inhibitor, Brinsupri, given in 10-mg and 25-mg tablets as a once-daily treatment for noncystic fibrosis bronchiectasis in adults and children 12 and older.
