RA PHARMACEUTICALS,INC. (NASDAQ:RARX) Files An 8-K Regulation FD Disclosure
Item 7.01. Regulation FD Disclosure.

Ra Pharmaceuticals,Inc. (the “Company”) from time to time presents and/or distributes to the investment community at various industry and other conferences slide presentations to provide updates and summaries of its business. A copy of its current corporate slide presentation (the “Presentation”) is attached to this Current Report on Form8-K as Exhibit99.1. The Company undertakes no obligation to update, supplement or amend the materials attached hereto as Exhibit99.1.

The information in Item 7.01 of this Form8-K, including Exhibit99.1 attached hereto, shall not be deemed “filed” for purposes of Section18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”) or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, except as expressly set forth by specific reference in such a filing.

Item 8.01. Other Events.

On June7, 2018, in connection with the presentation and/or distribution of the Presentation, the Company presented the following reticulocyte count data for the eculizumab switch cohort from the Company’s Phase 2 clinical trial of RA101495 SC in paroxysmal nocturnal hemoglobinuria, or PNH:

As depicted in the figure, a post-hoc analysis of the eculizumab switch cohort data demonstrated that an elevated absolute reticulocyte count (> 2 times the upper limit of normal) at the time of switching from eculizumab to RA101495 SC was an important predictor of breakthrough hemolysis during washout. These data are consistent with the observation that transfusion dependency on eculizumab was associated with switch failure.

Recent data from the PNH National Service in the United Kingdom has identified reticulocyte count as the single best indicator of extravascular hemolysis in PNH patients on eculizumab. These data demonstrated that reticulocyte count appears to be a better indicator of extravascular hemolysis than lactate dehydrogenase, correlating more strongly with raised bilirubin, increased C3-loading of PNH red blood cells and an increased transfusion requirement. We therefore believe that assessing reticulocyte count will allow us to better identify those patients who are more likely to be able to successfully switch from eculizumab to RA101495 SC.

About RA PHARMACEUTICALS,INC. (NASDAQ:RARX)

Ra Pharmaceuticals, Inc. is a United States-based clinical-stage biopharmaceutical company. The Company focuses on the development of therapeutics for diseases of complement dysregulation and a range of orphan indications. It utilizes small molecules and peptide approaches to address pathological targets in the complement cascade. It has leveraged the Extreme Diversity peptide chemistry platform to develop a portfolio of products that selectively inhibit the complement system and other immune targets. Its main program, RA101495, is a macrocyclic peptide inhibitor of complement component 5 (C5), which is in Phase I stage of development for the treatment of paroxysmal nocturnal hemoglobinuria (PNH). RA101495 binds a site on the C5 protein to inhibit cleavage into C5a and C5b, thereby preventing red blood cell lysis by inhibiting the production and assembly of the membrane attack complex (MAC). RA101495 is being developed as an alternative to eculizumab therapy for patients with PNH.
