In our yesterday’s article asking about how the FDA advisory committee has to vote regarding Biomarin product Kyndrisa (drisapersen) for Duchenne muscular dystrophy. We got the answer yesterday during the meeting that took a much longer time than committees’ meetings usually take.

Today, the FDA advisory panel will discuss BioMarin (BMRN) product drisapersen for Duchenne muscular dystrophy based on documents released to the committee by the FDA. The FDA said, “The benefit of drisapersen in exon 51 skip amenable patients is inconclusive at this time. Therefore, the benefit-risk assessments were not made.” Analysts interpreted the FDA statement as a condemnation of the drug, which does not really tell what the FDA meant …

Prohost Letter #383 The Market - Recent tails about the market and the biotech sector are true thrillers. By true we mean no-fiction. The accounts lack common sense.
