Akari Therapeutics Announces Upcoming Data Presentation at the 21st European Hematology Association Annual Congress and Update on First PNH Patient Treated

New York, New York, UNITED STATES

NEW YORK and LONDON, May 19, 2016 (GLOBE NEWSWIRE) -- Akari Therapeutics (NASDAQ:AKTX), an emerging growth, development-stage biopharmaceutical company, announced today that data on Coversin therapy in an eculizumab resistant paroxysmal nocturnal hemoglobinuria (PNH) patient will be presented at the 21st European Hematology Association (EHA) Annual Congress taking place in Copenhagen from June 9-12. Coversin, Akari’s lead clinical product, is a second-generation complement inhibitor that acts on complement component-C5, preventing release of C5a and formation of C5b-9 (also known as the membrane attack complex or MAC).

Summarized below is the poster title and presentation time. Additional information about the meeting can be found on the EHA website at http://www.ehaweb.org.

Poster Presentation:

12 Weeks Safety And Efficacy Results Of A Novel C5 Inhibitor Coversin In PNH With Resistance To Eculizumab Due To Complement C5 Polymorphism.

Lead Author: S. Langemeijer

Poster Number: LB2248

Date: June 10, 2016

Session Time: 9:30am CEST

As presented in the abstract, results have been obtained from the first patient administered Coversin for 90 days pursuant to a clinical trial protocol accepted by an EU national regulatory authority incorporating PNH patients with eculizumab resistance.  This patient was diagnosed with PNH in 2009 and had been determined to be resistant to eculizumab as established by both a recognized C5 polymorphism on genetic screening and complement inhibition on CH50 ELISA of <100% at concentrations of eculizumab in excess of 50µg/ml.  The patient presented with severe haemolysis (LDH 3 to 17xULN), and after approximately one month administration of a stable dose of Coversin, the LDH decreased to approximately 1.5xULN (nadir 347 and consistently below 500) and complement remained fully inhibited with CH50 levels <8 U Eq/ml (lower limit of quantification). The patient has returned to his full time occupation and it is expected that the patient will continue self-injection as per the protocol.  As noted in the abstract, “for the first time since he was diagnosed with PNH in 2009 the patient feels well with no symptoms of fatigue and no muscle dystonia. There have been no further haemolytic episodes. Twelve weeks after start of treatment, our patient did not have any drug-related adverse events, except occasional local and transient irritation at the injection site.” It is anticipated that further data from this clinical trial will be presented at future scientific forums.

Akari anticipates data from its ongoing Phase Ib evaluating a new lyophilized formulation as once daily subcutaneous maintenance administration to be available about June 2016.

Based on the results of these limited trial data, Akari believes that further evaluation of Coversin in PNH patients with or without resistance is warranted.  The company plans to initiate a Phase II study in PNH patients during the summer of 2016. There can be no assurance that these same or similar results will be achieved in future clinical trials involving more patients.

Coversin has not been clinically determined to be safe or effective for the purposes for which it is under investigation.  Safety and efficacy will be studied under clinical trial protocols accepted by national regulatory authorities in the future.
