Duchenne muscular dystrophy
The FDA has been trying to mend fences with rare disease drug developers and patient groups since the departure of former Commissioner Marty Makary three months ago. But advisory committee meetings last week for Replimune and Capricor Therapeutics only created more confusion and frustration.
The industry has been abuzz since the weekend when talks of a potential mega-merger between Bristol Myers Squibb and AstraZeneca were reported. Meanwhile, Pfizer, Merck and others release second quarter earnings, with some disclosing pipeline discontinuations and cost-cutting measures. Finally, all eyes turn to the FDA in the wake of heated advisory committee meetings for Capricor Therapeutics and Replimune.
After an FDA advisory committee voted 9-3 on Wednesday against recommending Capricor Therapeutics’ Duchenne muscular dystrophy cardiomyopathy drug for approval, stakeholders allege an “ulterior motive” and “biased intentions.”
Biotechs that announced series B financing this year and are looking for employees as they grow include one that received over $100 million and another that has a partnership with a Big Pharma company.
During a perplexing advisory committee meeting in which FDA reviewers focused largely on the Phase 3 HOPE-3 trial’s secondary endpoint of cardiac function, experts pointed to “very fragile” data. The committee voted 9-3 against approval of deramiocel.
The FDA published briefing documents ahead of advisory committee meetings for therapies from Capricor Therapeutics and Replimune indicate an uphill battle for the biotechs; GSK and AstraZeneca outline ambitious plans in second quarter presentations; Sarepta taps Michael Severino as its new CEO; and Amgen launches its official defense of Tavneos.
In briefing documents published Monday ahead of an advisory committee meeting for deramiocel, the FDA disagreed with Capricor’s assertion that a Phase 3 trial met its primary outcome measures.
After leaving Tessera Therapeutics earlier this month, Michael Severino will take over Sarepta Therapeutics as the biotech awaits two key regulatory decisions in Duchenne muscular dystrophy.
If approved, Dyne Therapeutics’ zeleciment rostudirsen could “capture the majority” of the exon-51 Duchenne muscular dystrophy market, given its better efficacy and dosing profile versus Sarepta Therapeutics’ exon-skipping therapy Exondys 51, the current standard of care, according to Oppenheimer.
Many of the FDA’s decisions this quarter involve applications that have previously been delayed, declined or outright rejected, including one for an mRNA vaccine that became the center of controversy earlier this year.
