“We continue to make important progress in advancing our lead clinical
candidate RA101495 SC in multiple, complement-mediated indications,”
Dr. Treco added, “We are excited by the recent appointment of John C. King as Chief Commercial Officer, given his background in commercializing Soliris® for generalized myasthenia gravis (gMG) in the U.S. and growth of paroxysmal nocturnal hemoglobinuria (PNH) in markets around the world. We look forward to initiating a Phase 3 clinical trial in PNH in the second half of this year, and to completing enrollment in our Phase 2 clinical trial in gMG, followed by data in the first half of 2019.”

About RA101495 SC
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.
About RA101495 SC Phase 2 PNH Clinical Program
The global, dose-finding Phase 2 program was designed to evaluate the safety, tolerability, preliminary efficacy, pharmacokinetics, and pharmacodynamics of RA101495 SC in patients with PNH. The study evaluated RA101495 SC in three cohorts. The first cohort included eculizumab-naïve patients, the second cohort included patients switching from eculizumab to RA101495 SC, and the third cohort included patients who were currently treated with eculizumab but had evidence of an inadequate response. Patients in all three cohorts were eligible for entry into a long-term extension study following the completion of the initial 12-week studies. The primary efficacy endpoint was the change in LDH from baseline to the mean level from week 6 to week 12.
About RA101495 SC Phase 2 gMG Clinical Program
The Phase 2, multicenter, randomized, double-blind, placebo-controlled trial is designed to evaluate the safety, tolerability, and preliminary efficacy of RA101495 SC in patients with gMG. The trial is designed to enroll approximately 36 patients and includes a screening period of up to four weeks. At the outset of the 12-week treatment period, patients will be randomized in a 1:1:1 ratio and will receive daily, subcutaneous doses of 0.1 mg/kg of RA101495 SC, 0.3 mg/kg of RA101495 SC, 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.
