|Ra Pharmaceuticals Reports Fourth Quarter and Full Year 2017 Financial Results and Provides Corporate Update|
“We made tremendous progress in 2017, advancing the development of our
lead candidate, RA101495, a convenient, subcutaneous (SC),
self-administered inhibitor of complement component 5 (C5). In addition
to advancing our global clinical program for the treatment of paroxysmal
nocturnal hemoglobinuria (PNH), we initiated a Phase 2 study in
generalized myasthenia gravis (gMG), the first of several additional
C5-mediated indications for RA101495 SC,” said
The top-line data from the recently completed Phase 2 PNH studies showed that RA101495 SC was well-tolerated and achieved consistent, sustained, and near-complete inhibition of C5. “These data provide the foundation for RA101495 SC to offer meaningful therapeutic value and, importantly, based on convenience and anticipated pricing flexibility, support expanded patient access and broad utility as a potential first line treatment option for complement-mediated diseases. We look forward to our upcoming end-of-phase 2 discussions with regulators, with the goal of initiating a registrational program in the second half of this year,” added Dr. Treco.
Collectively, the Phase 2 data support the selection of 0.3 mg/kg RA101495 SC daily as the recommended dose in our Phase 3 studies in PNH, which the Company plans to advance in treatment-naïve patients and transfusion-independent eculizumab-switch patients. These studies are anticipated to commence in the second half of 2018.
Fourth Quarter and Full Year 2017 Financial Results
For the fourth quarter of 2017, the Company reported a net loss
attributable to common shareholders of
Research and development expenses for the fourth quarter of 2017 were $12.6 million compared to $9.4 million for the same period in 2016. Research and development expenses for the full year 2017 were $45.3 million compared to $27.9 million for the full year 2016. The increase in R&D expenses for both the fourth quarter and full year were primarily due to primarily due to clinical development costs associated with our lead program, RA101495 SC, for the treatment of PNH.
General and administrative expenses for the fourth quarter of 2017 were $2.7 million, compared to $1.6 million for the same period in 2016. General and administrative expenses for the full year 2017 were $9.8 million, compared to $5.0 million for the full year 2016. The increase in G&A expenses for both the fourth quarter and the full year were primarily due to employee-related costs, including salary, benefits, and non-cash stock-based compensation due to the increase in G&A headcount to support the growth of the Company.

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 will enroll approximately 36 patients and will include 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.
