Rare diseases
Sarepta Therapeutics faces serious FDA action after news broke of a third patient death, the FDA gets a new top drug regulator in George Tidmarsh, a handful of new drugs get turned away from the market and pharma companies continue to commit billions to reshoring manufacturing.
In this episode presented by Eclipsebio, BioSpace’s head of insights Lori Ellis continues the discussion on mRNA and srRNA with Andy Geall of Replicate Bioscience and Alliance for mRNA Medicines and Pad Chivukula of Arcturus Therapeutics.
The company is pushing inhaled versions of common oral drugs with the hope of avoiding severe side effects.
The patient, who was being treated with an investigational gene therapy for limb-girdle muscular dystrophy, died of acute liver failure, the same complication responsible for the deaths of two boys taking Sarepta’s Duchenne muscular dystrophy treatment Elevidys.
