10 Nov, 2013 Positive Phase II Data with Patisiran (ALN-TTR02)
We presented positive data from our Phase II clinical trial of patisiran (ALN-TTR02) for the treatment of transthyretin-mediated amyloidosis (ATTR) at the International Symposium on Familial Amyloidotic Polyneuropathy, November 10 – 13, 2013. Results showed that multiple doses of patisiran led to robust and statistically significant knockdown of serum TTR protein levels of up to 96%, with mean levels of TTR knockdown exceeding 85%. Knockdown of TTR, the disease-causing protein in ATTR, was found to be rapid, dose dependent, and durable, and similar activity was observed toward both wild-type and mutant protein. In addition, patisiran was found to be generally safe and well tolerated in this study.
