Akari Announces Coversin Data to be Presented at 2018 Complement-Based Drug Development Summit

November 15, 2018

Highlights potential role of both complement and leukotriene pathways in a therapeutic mouse model of rheumatoid arthritis (RA)

NEW YORK and LONDON, Nov. 15, 2018 (GLOBE NEWSWIRE) -- Akari Therapeutics, Plc (NASDAQ:AKTX), a biopharmaceutical company focused on innovative therapeutics to treat orphan autoimmune and inflammatory diseases where complement and or leukotriene systems are implicated, today announced that PASylated Coversin data will be presented at the 2nd Annual 2018 Complement-Based Drug Development Summit in Boston, Mass. during an oral presentation by Andrew Luster, M.D., Ph.D., Chief, Division of Rheumatology, Allergy and Immunology & Director, Center for Immunology and Inflammatory Diseases Massachusetts General Hospital. The presentation will take place on November 15, 2018, at 9:10 a.m. EST.

In Dr. Luster’s RA model, PASylated Coversin, which is a longer half-life version of the parent molecule Coversin, and which similarly is able to inhibit both C5 and LTB4, was more effective than LTB4 inhibition alone, completely eliminating rheumatic symptoms within six days of initiating treatment.

These data point to an increasing potential set of clinical targets available to treatment with Coversin’s combined C5 and LTB4 functionality. Akari currently has two clinical programs open in bullous pemphigoid (BP) and atopic keratoconjunctivitis (AKC) where both C5 and LTB4 are believed to be implicated. The Company expects initial data readouts from both trials in the first quarter of 2019.

Dr. Luster stated, “The effect of Coversin (PASYlated) used therapeutically in our mouse model of RA was impressive with apparent total disease reversal. This highlights that the novel strategy offered by Coversin of simultaneously blocking both C5 and LTB4 may make it an effective anti-inflammatory treatment and offers the potential to provide an alternative therapy for RA patients who are unresponsive to current marketed therapies.”

About Akari TherapeuticsAkari is a biopharmaceutical company focused on developing inhibitors of acute and chronic inflammation, specifically for the treatment of rare and orphan diseases, in particular those where the complement (C5) or leukotriene (LTB4) systems, or both complement and leukotrienes together, play a primary role in disease progression. Akari’s lead drug candidate, Coversin, is a C5 complement inhibitor that also independently and specifically inhibits leukotriene B4 (LTB4) activity. Coversin is currently being clinically evaluated in four indications: bullous pemphigoid (BP), atopic keratoconjunctivitis (AKC), atypical hemolytic uremic syndrome (aHUS), and paroxysmal nocturnal hemoglobinuria (PNH). Akari believes that the dual action of Coversin on both C5 and LTB4 may be beneficial in AKC, BP, and aHUS. Akari is also developing other tick derived proteins, including longer acting versions.
