The EMA and the FDA have both agreed to a Phase III randomized placebo-controlled study with nomacopan in moderate to severe bullous pemphigoid (BP) patients with a primary endpoint of disease remission on minimal oral corticosteroids (OCS)

Nomacopan has been granted orphan drug designation by the EMA and the FDA for the treatment of BPNomacopan, with its dual inhibition of complement (C5) and leukotriene (LTB4) together with downstream cytokines, is a novel treatment for BP that has the potential to replace long term steroid treatment (standard of care), which has multiple adverse effects in this elderly and frail population
NEW YORK and LONDON, Oct. 01, 2020 (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 completion of a scientific advice meeting with the European Medicines Agency (EMA) in advance of initiating a Phase III pivotal study of nomacopan for the treatment of bullous pemphigoid (BP). Following prior similar agreement from the U.S. Food and Drug Administration (FDA) at an End of Phase II meeting, the EMA has agreed to Akari’s proposal for a Phase III randomized placebo-controlled study with nomacopan in patients with moderate to severe BP with a primary endpoint of disease remission on minimal oral corticosteroids (OCS). Akari believes the overlapping advice now received from both agencies allows the pivotal Phase III study design to satisfy both the FDA and EMA recommendations.BP is a severe orphan autoimmune inflammatory blistering skin disease with no approved treatments in the U.S. and Europe with an approximately three-fold increase in mortality in the BP population treated with current standard of care. The prevalence of BP is estimated to be over 100,000 patients in the U.S. and Europe.In the Phase III study, patients will be randomized to receive either nomacopan plus oral corticosteroids (OCS) or placebo plus OCS for six months. Following an initial stabilization phase, the steroids will be tapered according to disease response to a minimal level of OCS (< 0.1mg/kg/d prednisone or equivalent) which is considered safe. If disease response is rapid, as was seen in the nomacopan Phase II study in BP patients, OCS could be tapered to the minimal level within six weeks. Once patients are on minimal OCS plus either nomacopan or placebo, the primary endpoint will be achieved by those patients with complete disease remission on minimal OCS for eight weeks or longer during the 24-week treatment period. Patients will then enter an extension study to provide at least six months of additional data. An important secondary endpoint is reduction in cumulative OCS use on nomacopan as high dose OCS are regarded as unsafe in this vulnerable patient population.Clive Richardson, Chief Executive Officer of Akari Therapeutics, said, “Following our successful FDA End of Phase II meeting, we are very pleased that the EMA has also agreed that we can proceed with our proposed pivotal Phase III study. The advice received from both agencies provides a clear pathway to a potential approval in Europe and the U.S. for nomacopan in patients with BP. We plan to initiate the study in both the U.S. and Europe during the first half of 2021.”Background on Bullous Pemphigoid (BP)In BP patients there is evidence that both terminal complement activation (via complement component C5) and the lipid mediator leukotriene B4 (LTB4) have a central role in driving the disease. Ex vivo data in BP patients, published in the August 2019 edition of JCI Insight, showed a pronounced accumulation of LTB4 and C5 and its activation products in the inflamed skin of BP patients. This underlies the rationale for treatment with nomacopan which is a unique bifunctional inhibitor of both C5 and LTB4 and a range of downstream cytokines. In addition to BP, the Company believes this unique mode of action underpins the activity of nomacopan across the Company’s other target conditions – TMA-HSCT, COVID pneumonia and ophthalmology as well as other emerging clinical indications.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, nomacopan (formerly known as Coversin), is a C5 complement inhibitor that also independently and specifically inhibits leukotriene B4 (LTB4) activity.Cautionary Note Regarding Forward-Looking Statements
