Sarepta Therapeutics is now recruiting patients at two Canadian centres for their ESSENCE clinical trial.
The ESSENCE trial is a 96-week, double-blind, placebo-controlled research study to evaluate the effectiveness and safety of investigational products, SRP-4045 and SRP-4053, in patients with Duchenne muscular dystrophy.
The ESSENCE trial is currently recruiting patients at two Canadian locations:
London Health Sciences Centre
London, Ontario, Canada, N6A 5W9
Contact: Gina Bhullar (519) 685-8500 ext 55058 email@example.com
Principal Investigator: Craig Campbell, MD
Alberta Childrens Hospital
Calgary, Alberta, Canada, T3B 6A8
Contact: Tiffany Haig (403) 955-3192 firstname.lastname@example.org
Principal Investigator: Jean Mah, MD

Duchenne is caused by mutations to the dystrophin gene. Most commonly, one or more exons (a portion of the gene) are missing, and the remaining exons don’t ﬁt together properly. Because of this error, cells cannot make dystrophin, a protein muscles need to work properly. Without dystrophin, muscle cells are damaged, and, over time, are replaced with scar tissue and fat.
The investigational therapies in the ESSENCE study use a technique referred to as exon skipping. Skipping a specific exon next to the mutation is intended to allow the body to make a shortened form of the dystrophin protein.
