NEW YORK and LONDON, July 13, 2023 (GLOBE NEWSWIRE) -- Akari Therapeutics, Plc (Nasdaq: AKTX), a late-stage biotechnology company developing advanced therapies for autoimmune and inflammatory diseases, today announced updates in the development programs investigating nomacopan in pediatric and adult hematopoietic stem cell transplant-related thrombotic microangiopathy (HSCT-TMA). Akari is on track to begin patient enrollment in the registrational Phase 3 study of nomacopan in pediatric HSCT-TMA that is expected to produce safety and efficacy data supportive of a potential regulatory filing and approval. Akari also is planning to move forward into a Phase 3 double-blind placebo-controlled clinical trial of nomacopan in adult HSCT-TMA and to open enrollment in 2024.
“Our goal is to bring an approved treatment to both children and adults in desperate need, and we are deeply committed to making a positive impact on the standard of care now and down the road for patients facing this devastating condition,” said Rachelle Jacques, Akari President and CEO.
HSCT-TMA is a rare complication of stem cell transplant, and it is a clinical diagnosis which is based on signs, symptoms, patient history, and physical exam. Currently, there are no approved treatments for HSCT-TMA and among patients who have severe disease there is a mortality rate of about
Consensus guidelines were recently published by an international panel of experts that harmonize diagnosis criteria and support earlier screening and diagnosis in the care of patients.1 Historically, a lack of harmonization of diagnostic and prognostic markers has caused difficulties in the interpretation of patient outcomes. The consensus criteria are a crucial advancement to support earlier screening and diagnosis in the care of patients with transplant-associated TMAs that are associated with significant mortality once multiorgan dysfunction occurs, which is difficult to reverse. The Akari HSCT-TMA Phase 3 clinical trials design has been significantly informed by these consensus criteria for earlier diagnosis of high-risk (severe) patients.
“There is consensus that prospective screening and early diagnosis of TMA following transplantation can save lives by heading off the multiorgan dysfunction that is too often irreversible and fatal,” said Sonata Jodele, M.D., Cincinnati Children’s Hospital Medical Center.
Akari is advancing into Phase 3 open-label single-arm study of nomacopan in pediatric HSCT-TMA and is planning to move into a Phase 3 double-blind placebo-controlled study of nomacopan in adult HSCT-TMA in 2023 and 2024, respectively. These advancements to Phase 3 clinical trials were supported by Akari’s PK/PD data (in adults) and U.S. Food and Drug Administration (FDA) agreement that PK/PD modelling and predictions about pediatric dosing were sufficient to move forward.
“It is important that there is harmonization between adult and pediatric studies with the study design, such as inclusion criteria, because comparability in our clinical trials data will not only help future researchers but will also help bring clarity to regulators as they review our applications for approval,” said John Neylan, M.D., Akari Chief Medical Officer.
Orphan Drug, Fast Track, and Rare Pediatric Disease designations have been granted by the FDA for nomacopan in pediatric HSCT-TMA. With the Rare Pediatric Disease Designation, a sponsor who receives an approval of a new drug application (NDA) or biologics license application (BLA) is eligible for a Priority Review Voucher (PRV) to either redeem for priority review of a subsequent marketing application for a different product or sell to a third party. Akari was recently issued a positive opinion by the European Medicines Agency (EMA) on the company’s application for orphan drug designation for nomacopan as a treatment in hematopoietic stem cell transplantation.
