NEW YORK and LONDON, March 30, 2017 (GLOBE NEWSWIRE) -- Akari Therapeutics (NASDAQ:AKTX), an emerging growth, clinical-stage biopharmaceutical company, announced today that the US Food and Drug Administration (FDA) has granted Fast Track designation for Coversin™ for treatment of paroxysmal nocturnal hemoglobinuria (PNH) in patients who have polymorphisms conferring eculizumab resistance. Coversin™ is a second-generation complement inhibitor that acts on complement component-C5, preventing the release of C5a and the formation of C5b–9 (also known as the membrane attack complex or MAC), and independently also inhibits LTB4 activity.
“We are very proud of the continued advancement of our Coversin program for the treatment of PNH in patients with or without polymorphisms,” said Dr. Gur Roshwalb, Chief Executive Officer of Akari Therapeutics. “The FDA fast track designation recognizes the unmet need in patients with PNH who cannot be treated with the current standard of care due to polymorphisms.”
Akari is evaluating Coversin in two Phase 2 clinical trials. The first Phase 2 trial is evaluating Coversin™ in patients with PNH who have never received a complement blocking therapy. Interim results from this ongoing Phase 2 trial will be presented at the recently announced Research and Development Day to be held on April 24, 2017 in New York. The second Phase 2 trial is evaluating Coversin in patients with PNH and C5 polymorphisms resistant to eculizumab. One patient has been enrolled in this trial and has demonstrated significant LDH reduction and complete complement blockade with self-administered subcutaneous Coversin™ for over one year.
The Fast Track program was created by the FDA to facilitate the development and expedite the review of new drugs which show promise in treating a serious or life-threatening disease and address an unmet medical need. Drugs that receive this designation benefit from more frequent communications and meetings with FDA to review the drug's development plan including the design of the proposed clinical trials, use of biomarkers and the extent of data needed for approval. Drugs with Fast Track Designation may qualify for priority review to expedite the FDA review process, if relevant criteria are met.
About Akari Therapeutics Plc
Akari is a clinical-stage biopharmaceutical company focused on the development and commercialization of life-transforming treatments for a range of rare and orphan autoimmune and inflammatory diseases caused by dysregulation of complement C5 and Leukotriene B4 (LTB4), including paroxysmal nocturnal hemoglobinuria (“PNH”), atypical Hemolytic Uremic Syndrome (“aHUS”), and Guillain Barré syndrome (“GBS”). Akari’s lead product candidate, Coversin™ complement inhibitor, a second-generation complement inhibitor, acts on complement component-C5, preventing the release of C5a and the formation of C5b–9 (also known as the membrane attack complex or MAC), and independently also inhibits LTB4 activity. C5 inhibition is growing in importance in a range of rare autoimmune diseases related to dysregulation of the complement component of the immune system, including PNH, aHUS, and GBS. Exploiting the power of nature, Akari is also developing other tick derived proteins and expects to bring additional compounds to clinical trials over the next several years. The pipeline is focused on developing bioengineered versions of native tick salivary proteins that act as anti-inflammatory compounds allowing the tick to remain on its host. These compounds include PGP sparing LTB4 inhibitors, classical and alternative complement inhibitors, anti-histamines, and serotonin inhibitors as examples. Akari is also developing engineered forms that allow for potential oral absorption, as, for example, a potential orally absorbed C5 inhibitor, and tissue specific proteins, as, for example, Coversin™ that acts specifically at the neuromuscular junction for diseases like myasthenia gravis.
