|Dimension Therapeutics Announces FDA Acceptance of Investigational New Drug Application for DTX301 to Treat OTC Deficiency|
On Track to Initiate Phase 1/2 Global, Multi-Center Clinical Trial by Year End 2016
Most Advanced of Five Inherited Metabolic Disease Programs Progressing Towards Clinical Testing
DTX301 is designed to deliver stable expression and activity of OTC following a single intravenous infusion and has been shown in academic preclinical studies in relevant mouse models to normalize levels of urinary orotic acid, a marker of ammonia metabolism. In the late onset form of the disease, elevated ammonia can lead to significant medical issues for patients who are in need of better disease-modifying therapies.
“FDA’s acceptance of DTX301’s IND for the treatment of OTC Deficiency is a key pipeline milestone for Dimension. We are pleased to continue the momentum and advancement of our leading pipeline that addresses important inherited metabolic disorders of the liver,” said Dr.
Background on OTC Deficiency
OTC deficiency, the most common urea cycle disorder, is caused by a genetic defect in a liver enzyme responsible for detoxification of ammonia. Individuals with OTC deficiency can build up excessive levels of ammonia in their blood, potentially resulting in neurological deficits and other toxicities. It is estimated that more than 10,000 patients are affected by OTC deficiency worldwide, of which approximately 80% are classified as late-onset, Dimension’s target population. The greatest percentage of patients, including males and females, experience late-onset disease, representing a clinical spectrum of disease severity. Neonatal onset disease occurs in males, presents as severe disease, and can be fatal at an early age. Approved therapies, which must be taken multiple times a day for the patient's entire life, do not eliminate the risk of future metabolic crises. Currently, the only curative approach is liver transplantation.
