Momenta Pharmaceuticals,Inc. (NASDAQ:MNTA) Files An 8-K Other Events
Item 8.01 Other Events.

On November 29, 2016, Momenta Pharmaceuticals, Inc. (the “Company”) announced that the confirmatory Phase 3 clinical study of M923, a biosimilar HUMIRA® (adalimumab) candidate, in patients with moderate-to-severe chronic plaque psoriasis, met its primary endpoint. The proportion of subjects who achieved the primary endpoint, at least 75% reduction in the Psoriasis Area and Severity Index (PASI-75) following 16 weeks of treatment, was equivalent with M923 or HUMIRA. The estimated difference in responders was well within the pre-specified confidence interval, confirming equivalence.

Equivalence was also achieved for all secondary efficacy endpoints, including the achievement of PASI-50, PASI-90, proportion achieving clear or near-clear skin, and change from baseline in absolute PASI score. Adverse events were comparable in terms of type, frequency, and severity, and were consistent with the published safety data for HUMIRA.

The study was a confirmatory, randomized, double-blind, multicenter study evaluating the efficacy, safety and immunogenicity of M923 in adult patients with moderate-to-severe chronic plaque psoriasis. Patients received up to 48 weeks treatment with M923, HUMIRA, or HUMIRA alternating with M923. The full dataset from this study will be presented at future conferences and in future publications.

M923 was developed to a Development, License and Option Agreement, dated as of December 22, 2011 (the “Agreement”), by and between the Company and Baxalta US Inc., Baxalta GmbH and Baxalta Incorporated (collectively, “Baxalta”). As previously reported, in September 2016, the Company received written notice from Baxalta that Baxalta had exercised its right to terminate for its convenience the Agreement.
