Akari Therapeutics Announces Further Clinical Progress
Completion of enrollment into COBALT, the Phase II PNH trial of Coversin™
NEW YORK and LONDON, October 11, 2017 - Akari Therapeutics, Plc (NASDAQ: AKTX), a biopharmaceutical company focused on developing inhibitors of acute and chronic inflammation, specifically the complement system, the eicosanoid system and the bioamine system for the treatment of rare and orphan diseases, announces that three additional patients have been enrolled in the ongoing Phase II COBALT clinical trial of Coversin™ in patients with paroxysmal nocturnal hemoglobinuria (PNH).
COBALT, the Phase II 90-day, open label single arm clinical trial, has enrolled a total of eight patients, four of whom have completed the trial and were reported on at the European Hematology Association conference in June 2017. These four patients have all moved into Akari’s long-term safety study, CONSERVE. One of the initial five patients enrolled in the COBALT trial, with a suspected co-morbidity unrelated to the treatment, was withdrawn from the study on day 43.
Three new patients were enrolled pursuant to an amended protocol based on a revised dosing regimen which included changing the maintenance phase from a single dose of 30mg every 24 hours to a single dose of 45mg every 24 hours. The three newly enrolled patients on the revised dosing regimen have now completed approximately 8, 3 and 2 weeks, respectively. The primary endpoint in this clinical trial is reduction in serum LDH (lactate dehydrogenase; an indication of hemolysis) to ≤1.8 times the ULN (upper limit of normal) for the investigator’s reference laboratory or 500 I U/L, whichever is the lower from day 1 (pre-dose) to day 28. The first of the three patients had a LDH value of 1.5 times the ULN at day 28. The other two patients have not yet reached the primary endpoint measurement date. To date, there have been no drug-related serious adverse events. The data reported is taken from the current electronic case report forms.
Akari plans to provide an update on all PNH patients currently enrolled at the American Society of Hematology Annual Meeting to be held December 9-12, 2017.
Akari plans to advance Coversin towards Phase III clinical trials beginning with CAPSTONE in Q1 2018, a Phase III clinical trial of Coversin in naïve PNH patients.
About Akari Therapeutics
Akari is a biopharmaceutical company focused on developing inhibitors of acute and chronic inflammation, specifically the complement system, the eicosanoid system and the bioamine system for the treatment of rare and orphan 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.
