Full data shows safety, tolerability and proof-of-mechanism in healthy volunteers
CAMBRIDGE, Mass., Nov. 07, 2018 (GLOBE NEWSWIRE) -- Momenta Pharmaceuticals, Inc. MNTA today announced the publication of results from its Phase 1 study of M281 in healthy volunteers in the online edition of the peer-reviewed journal Clinical Pharmacology & Therapeutics. The paper, containing the full data from the Phase 1 study, is entitled M281, an Anti-FcRn Antibody: Pharmacodynamics, Pharmacokinetics and Safety across the Full Range of IgG Reduction in a First-In-Human Study. The paper will also appear in an upcoming print edition of the journal. A link to the online article can be accessed here: Link
"We are encouraged by the rapid onset and duration of target receptor occupancy, maximal reduction of circulating IgGs, and dose-dependent effect observed in this study, which demonstrates that M281 safely functions as designed in healthy volunteers and validates its mechanism," said Santiago Arroyo, M.D., Ph.D., Senior Vice President of Development and Chief Medical Officer of Momenta Pharmaceuticals. "These results support M281's continued development as a potential best-in-class anti-FcRn treatment for patients with immune-mediated diseases. We look forward to advancing the program into two Phase 2 studies, one in myasthenia gravis and one in hemolytic disease of the fetus and newborn, in the fourth quarter of 2018."
The Phase 1 randomized, double-blind, placebo-controlled single and multiple ascending dose study evaluated the safety, tolerability, pharmacokinetics and pharmacodynamics of M281 in 50 healthy volunteers over a 98-day period. M281 exhibited rapid onset of target receptor occupancy, dose-dependent pharmacodynamics, a self-limited IgG decrease to a mean maximum percent reduction of approximately 84% of baseline, and loss of target occupancy and IgG recovery observed at consistent times after the last dose. Single doses up to 60 mg/kg or 15 or 30 mg/kg administered weekly for up to 4 weeks by intravenous infusion were well-tolerated with no serious adverse events, few moderate adverse events (AEs) and a low incidence of other AEs, similar to placebo treatment.
About M281, anti-FcRn antibody
M281 is a fully human anti-neonatal Fc receptor (FcRn), aglycosylated immunoglobulin G (IgG1) monoclonal antibody, engineered to reduce circulating pathogenic IgG antibodies, by blocking endogenous IgG recycling via FcRn. Momenta reported positive data showing safety, tolerability and proof of mechanism for M281 in a phase 1 single ascending dose (SAD) and multiple ascending dose (MAD) study of normal human volunteers. Over the 98-day MAD study, M281 exhibited no serious adverse events, was well tolerated, and decreased circulating IgG levels up to 89% with a mean reduction of 84%. Momenta plans to commence two Phase 2 proof of concept studies, one in myasthenia gravis (MG) and one in hemolytic disease of the fetus and newborn (HDFN), in the fourth quarter of 2018.
About Momenta Pharmaceuticals
Momenta is a biotechnology company with a validated innovative scientific platform focused on discovering and developing novel therapeutics to treat rare, immune-mediated diseases. Momenta's lead product candidate, M281, is a potentially best-in-class anti-FcRn antibody; M254, is a hyper-sialylated human immunoglobulin (hsIgG) designed as a high potency alternative to intravenous immunoglobulin (IVIg); and M230 (CSL730), is a potential first-in-class novel recombinant Fc multimer being developed in collaboration with CSL. Momenta also has a focused pipeline of two biosimilar candidates: M710, a proposed biosimilar to EYLEA® being developed in collaboration with Mylan, and M923, Momenta's wholly-owned proposed biosimilar to HUMIRA®. Momenta's two FDA-approved complex generic products, enoxaparin sodium injection and Glatopa® (glatiramer acetate injection), are marketed by its collaboration partner, Sandoz.
