Late-onset glycogen storage disease type II (Pompe disease) in children and adults
Trial or other data
Nov 21PIII COMET Study (n=100) reports avalglucosidase alfa was non-inferior to alglucosidase alfa at week 49 in terms of improvement in respiratory function, (least-squares mean improvement in upright FVC% predicted of 2.89% vs. 0.46%, respectively) .
Nov 20Sanofi say that avalglucosidase alfa is specifically designed to deliver more GAA enzyme into the lysosomes of the muscle cells and trial results are encouraging. 
Oct 16Sanofi initiates the PIII COMET study of GZ 402666 in patients with glycogen storage disease (Pompe disease) type II (NCT02782741). The study will evaluate the efficacy and safety of repeated biweekly IV infusions of GZ 402666 (20 mg/kg) in comparison with alglucosidase alfa in treatment-naïve patients with late-onset Pompe disease. Primary outcome measure for the trial will be change in percent predicted forced vital capacity (%FVC). The randomised, double-blind study is enrolling approximately 96 patients, aged 3 years and older, in the US, Belgium, Denmark, France, the Netherlands, Sweden and the UK .
Collection of primary outcome data in the PIII COMET study (NCT02782741) is expected to complete Oct 20 .
