Positive FDA Meeting Outlines Path Ahead for Akari Therapeutics’s Coversin in Hematopoietic Stem Cell Transplant-Related Thrombotic Microangiopathy (HSCT-TMA)


  • HSCT-TMA trial in pediatric patients expected to start Q4 2019 following recent FDA feedback

NEW YORK and LONDON, March 13, 2019 (GLOBE NEWSWIRE) -- Akari Therapeutics, Plc (Nasdaq: AKTX), a biopharmaceutical company focused on innovative therapeutics to treat orphan autoimmune and inflammatory diseases where the complement and/or leukotriene systems are implicated, announces that it had a successful Type B, pre-IND meeting with the Food and Drug Administration (FDA) regarding Akari’s proposed pivotal clinical trial program for pediatric hematopoietic stem cell transplant-related thrombotic microangiopathy (HSCT-TMA). HSCT-TMA is an orphan condition with an estimated fatality rate of more than 80% in children with the severe disease.1

A framework for the trial design was agreed to with the FDA in which the response to Coversin of selected, clinically meaningful treatment variables would be the primary endpoint in the proposed pivotal trial. These responder endpoints were based on work done by Sonata Jodele, M.D., a world-leading expert in treating pediatric HSCT-TMA.

In September 2018, Akari announced, in relation to treatment variables, that in the first two patients treated with Coversin as part of a UK named patient program, it had observed a rapid reduction of the markers of complement activation as well as normalization of markers that are elevated in thrombotic microangiopathy (TMA). These markers include platelet count, red blood cell fragments, thrombocytopenia, elevated lactate dehydrogenase (LDH) and hypertension.

Clive Richardson, interim CEO of Akari Therapeutics, said, “Akari plans to commence a trial in European and U.S. pediatric HSCT-TMA patients in the fourth quarter of 2019. We see HSCT-TMA as a gateway indication into a range of other poorly treated orphan TMAs, and are enthusiastic about the potential of Coversin to offer an improved standard of care for patients with these rare and usually fatal conditions.”

About Akari Therapeutics

Akari 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 biopharmaceuticals, including longer acting versions of Coversin.
