Akari Therapeutics Announces Successful Scientific Advice Meeting with the European Medicines Agency (EMA) Establishing a Clear Path in Both U.S. and Europe for a Pivotal Phase III Study of Nomacopan for Treatment of Bullous Pemphigoid
- 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 BP
- Nomacopan, 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
BP is a severe orphan autoimmune inflammatory blistering skin disease with no approved treatments in the
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.
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
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.
