$AKTX Announces Regulatory Progress Following FDA Meeting

Plans to start Coversin Phase III in PNH in Q1 2018

NEW YORK and LONDON, Sept. 21, 2017 — Akari Therapeutics (NASDAQ:AKTX), a biopharmaceutical company focused on the development and commercialization of innovative therapeutics to treat orphan autoimmune and inflammatory diseases, announces that, following advice from a recent FDA Type B End of Phase II Meeting, it plans to advance its lead investigational drug, Coversin™, towards Phase III clinical studies in Paroxysmal Nocturnal Hemoglobinuria (PNH) in Q1 2018.

“Following our recent FDA meeting, we are working to initiate a Phase III clinical trial of Coversin in PNH in Q1 2018,” said Dr. David Horn Solomon, Chief Executive Officer of Akari Therapeutics. “We will continue to work closely with the FDA, benefitting from our Fast Track status in the U.S., and with the EMA towards submission of a BLA and MAA, respectively, for Coversin in PNH.”

Akari plans to carry out two Phase III clinical studies: CAPSTONE, in naïve PNH patients where eculizumab (Soliris®; Alexion) is not the standard of care, with co-primary clinical endpoints based on hemoglobin and transfusion data, and ASSET, a Phase III clinical study switching PNH patients from eculizumab, the current standard of care treatment in PNH in the U.S., to treatment with Coversin.

The FDA indicated that providing safety and efficacy data from the Company’s clinical trials for the proposed number of unique PNH patients on Coversin for more than one year seems reasonable, subject to review of the actual data upon submission. The number proposed includes patients having C5 polymorphisms conferring eculizumab resistance.

“Akari continues to build momentum in its complement focused therapy by advancing Coversin towards Phase III in PNH and Phase II in aHUS. With Coversin delivered subcutaneously, patients may have greater independence due to self-administration. Phase II studies are also planned for a number of other indications where Coversin’s actions on both the complement and leukotriene (LTB4) pathways play a role. Its two leading targets in this area are atopic keratoconjunctivitis (AKC), a rare eye disorder and severe bullous pemphigoid (BP), a rare skin disorder,” added Solomon.

About Akari Therapeutics
Akari is a biopharmaceutical company focused on the development and commercialization of innovative therapeutics to treat orphan autoimmune and inflammatory diseases, in particular those where the complement system or leukotrienes or both complement and leukotrienes together play a primary role in disease progression. Akari’s lead drug candidate Coversin is a C5 complement inhibitor currently being evaluated in paroxysmal nocturnal hemoglobinuria (PNH) and atypical hemolytic uremic syndrome (aHUS). In addition to its C5 inhibitory activity, Coversin independently and specifically inhibits leukotriene B4 (LTB4) activity. Akari intends to evaluate Coversin in two conditions, the skin and eye diseases bullous pemphigoid and atopic keratoconjunctivitis, where the dual action of Coversin on both C5 and LTB4 may be beneficial. Akari is also developing other tick derived proteins, including long acting versions.
