Ra Pharmaceuticals to Present at the 4th Congress of the European Academy of Neurology
CAMBRIDGE, Mass.--(BUSINESS WIRE)--Jun 5, 2018--Ra Pharmaceuticals, Inc. (NASDAQ:RARX) today announced that the design of its Phase 2 clinical trial of RA101495 SC for the treatment of generalized myasthenia gravis (gMG) will be presented at the 4 th Congress of the European Academy of Neurology (EAN), taking place June 16-19, 2018 in Lisbon, Portugal. The Phase 2 trial design will be presented along with previously detailed Phase 1 clinical trial results evaluating the safety, tolerability, pharmacokinetics, and pharmacodynamics of RA101495 SC in healthy volunteers.
“Complement C5 is a validated target for treating gMG, but currently available options are difficult to access, and the need for high-volume intravenous infusions places a burden on patients suffering with this lifelong disease. This creates an opportunity to deliver a more convenient, accessible therapy such as RA101495 SC to benefit a larger population of patients with gMG,” said Ramin Farzaneh-Far, MD, Chief Medical Officer of Ra Pharma. “As a once-daily, low-volume, subcutaneous (SC), self-administered therapy, we believe RA101495 SC has the potential to transform complement therapeutics in gMG.”
Initiated in December 2017, the Phase 2, multicenter, randomized, double-blind, placebo-controlled trial is designed to evaluate the safety, tolerability, and preliminary efficacy of RA101495 SC in approximately 36 patients with gMG. At the outset of a 12-week treatment period, patients are randomized in a 1:1:1 ratio and receive daily, SC doses of 0.1 mg/kg of RA101495, 0.3 mg/kg of RA101495, or matching placebo. The primary efficacy endpoint is change in Quantitative Myasthenia Gravis (QMG) score from baseline to week 12. All patients will have the opportunity to receive RA101495 SC in a long-term extension study.
To date, 19 patients, over 50% of target enrollment, have been dosed in the trial, and the Company remains on track to report data from the study in the first half of 2019.
Details of the poster presentations are as follows:

Myasthenia gravis (MG) is a chronic, autoimmune, neuromuscular disease characterized by weakness and fatigue of skeletal muscles. Patients with MG present with muscle weakness that becomes increasingly severe with repeated use and recovers with rest. Weakness can be localized to specific muscles, such as those responsible for eye movements, but often progresses to affect a broader range, including head, limb, and respiratory muscles. This progression is often described as the generalized, or severe, form of the disease. gMG is estimated to affect over 80,000 individuals worldwide.
Ra Pharma is developing RA101495 SC for paroxysmal nocturnal hemoglobinuria (PNH), generalized myasthenia gravis (gMG), atypical hemolytic uremic syndrome (aHUS), and lupus nephritis (LN). The product is designed for convenient, once-daily subcutaneous self-administration. RA101495 SC is a synthetic, macrocyclic peptide discovered using Ra Pharma’s powerful proprietary drug discovery technology. The peptide binds complement component 5 (C5) with sub-nanomolar affinity and allosterically inhibits its cleavage into C5a and C5b upon activation of the classical, alternative, or lectin pathways. By binding to a region of C5 corresponding to C5b, RA101495 SC is designed to disrupt the interaction between C5b and C6 and prevent assembly of the membrane attack complex (MAC). This activity may define an additional, novel mechanism for the inhibition of C5 function.
