Poland and U.K. Regulatory Authorities – URPL and MHRA – Approve Use of New, Higher-Yielding Manufacturing Process for Nomacopan in Pivotal Clinical Study

• Third generation drug substance manufacturing process increases the final yield of nomacopan by at least 5-fold, improving cost efficiencies in the continuing Phase 3 clinical trial of nomacopan in pediatric hematopoietic stem cell transplant-related thrombotic microangiopathy (HSCT-TMA) advancing to pivotal Part B later this year

NEW YORK and LONDON, March 29, 2023 (GLOBE NEWSWIRE) — Akari Therapeutics, Plc (Nasdaq: AKTX), a late-stage biotechnology company developing advanced therapies for autoimmune and inflammatory diseases, today announced  regulatory authorities in Poland (Office for Registration of Medicinal Products, Medical Devices and Biocidal Products/URPL) and the U.K. (Medicines & Healthcare products Regulatory Agency/MHRA) have approved amendments to the company’s Investigational Medicinal Product Dossier (IMPD) and Clinical Trial Authorisation (CTA), respectively, for clinical use of the third-generation drug substance manufacturing process that increases the final yield of nomacopan by at least 5-fold. Nomacopan is an investigational bispecific inhibitor of both complement C5 and leukotriene B4 (LTB4) currently in Phase 3 clinical trials for pediatric hematopoietic stem cell transplant-related thrombotic microangiopathy (HSCT-TMA).

“The clearance by regulators in the U.K. and Poland of Akari’s newer, enhanced manufacturing process for nomacopan is another important step forward in our progress toward the pivotal Part B in our clinical trials in pediatric HSCT-TMA,” said Rachelle Jacques, President and Chief Executive Officer of Akari Therapeutics.

The Phase 3 study of nomacopan in pediatric HSCT-TMA includes clinical trial sites in Poland, the U.K. and U.S.
