CRESTWOOD, Ky. and WALTHAM, Mass., Nov. 01, 2018 (GLOBE NEWSWIRE) -- Apellis Pharmaceuticals Inc. (Nasdaq:APLS), a clinical-stage biopharmaceutical company focused on the development of novel therapeutic compounds to treat disease through the inhibition of the complement system, announced today that two abstracts related to the company’s hematology program have been accepted for poster presentations at the 60th American Society of Hematology (ASH) Annual Meeting and Exposition, to be held in San Diego, California, from December 1-4, 2018. The abstracts were published today on the ASH conference website.

One abstract provides updates on PADDOCK, a Phase 1b open-label, dose-escalation trial designed to assess the safety, tolerability, pharmacokinetics (PK), pharmacodynamics (PD) and efficacy of multiple doses of APL-2, administered by daily subcutaneous injection (SC), in patients with paroxysmal nocturnal hemoglobinuria (PNH). The second abstract provides updates on PLAUDIT, a Phase 2, open-label trial assessing the safety, tolerability, efficacy, and PK of multiple subcutaneous (SC) doses of APL-2 administered daily in patients with autoimmune hemolytic anemia (AIHA), including warm autoimmune hemolytic anemia (wAIHA) and cold agglutinin disease (CAD).

In accordance with ASH policies, abstracts submitted to the ASH Annual Meeting are embargoed from the time of submission.

About APL-2 
APL-2 is designed to inhibit the complement cascade centrally at C3 and may have the potential to treat a wide range of complement-mediated diseases more effectively than is possible with partial inhibitors of complement. APL-2 is a synthetic cyclic peptide conjugated to a polyethylene glycol (PEG) polymer that binds specifically to C3 and C3b, effectively blocking all three pathways of complement activation (classical, lectin, and alternative). 

Clinical trials 
Apellis is currently evaluating APL-2 in two Phase 1b trials (PHAROAH and PADDOCK) for systemic administration in paroxysmal nocturnal hemoglobinuria. Previously reported interim data from these trials showed improvements in lactate dehydrogenase and hemoglobin levels in patients who are suboptimal responders to eculizumab and untreated patients, respectively. Apellis is also testing APL-2 for systemic administration in a Phase 2 clinical trial in autoimmune hemolytic anemia (AIHA) and a Phase 2 clinical trial in complement dependent nephropathies, as well as a Phase 3 trial for patients with PNH.

About Apellis
Apellis Pharmaceuticals, Inc. is a clinical-stage biopharmaceutical company focused on the development of novel therapeutic compounds for the treatment of a broad range of life-threatening or debilitating autoimmune diseases based upon complement immunotherapy through the inhibition of the complement system at the level of C3. Apellis is the first company to advance chronic therapy with a C3 inhibitor into clinical trials. For additional information about Apellis and APL-2, please visit http://www.apellis.com.
