1. Therapeutics for the Muscular Dystrophies

2.  Mission  Increase the longevity and quality of life of patients with muscular dystrophy  Lead Drug Candidate – LAM-111  Delivered systemically to MDC1A and DMD mouse models  Excellent efficacy with no toxicity  Human LAM-111 in human MDC1A and DMD cells  Human LAM-111 in mouse MDC1A and DMD muscle cells  Stable and scalable human LAM-111 manufacturing process  Under evaluation for treatment of dystroglycanopathy and dysferlinopathy Ashley

3. SAM Human LAM-111 No LAM-111

4. Merosin Deficient (MDC1A) mouse treated with laminin-111 (10mg LAM-111/kg/week starting at 10 days of age) Merosin Deficient (MDC1A) mice have a reduced lifespan and normally live between 6- 15 weeks of age, so 1 year is a very significant milestone Picture provided by Prothelia collaborator Dr. Dean Burkin, University of Nevada, Reno Adelina
