CRESTWOOD, KY, and WALTHAM MA, USA I June 26, 2018 I 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, today announced that it has commenced its PEGASUS Phase 3 trial assessing the safety and efficacy of APL-2 in patients with paroxysmal nocturnal hemoglobinuria (PNH) compared to eculizumab (Soliris™). The development was highlighted at the end of Apellis’ R&D Day, where the company provided important clinical updates on its PNH program.
PNH is a rare, acquired, potentially life-threatening disease characterized by complement-mediated thrombosis and hemolytic anemia. Apellis is developing APL-2, a novel inhibitor of complement factor C3 as a next generation monotherapy, with the goal of improving anemia and transfusion dependency in patients with PNH. In a recent study, up to 70% of patients treated with eculizumab (the only currently approved therapy for PNH) were anemic with hemoglobin levels below 12.0 g/dL.1
PEGASUS is a 70-patient, randomized, head-to-head study comparing APL-2 monotherapy to eculizumab monotherapy in patients currently on treatment with eculizumab who have a hemoglobin level <10.5 g/dL, regardless of eculizumab dose or transfusion history. Patients will be co-treated for 4 weeks with subcutaneous injection twice weekly dosing of APL-2 with eculizumab and then randomized 1:1 to either APL-2 monotherapy or eculizumab monotherapy and monitored for 56 weeks. The primary endpoint will be the week 16 change from baseline in hemoglobin levels. Hemoglobin response is defined as a 1.0 g/dL increase in hemoglobin from baseline at week 16. Secondary endpoints include week 16 change from baseline in reticulocyte count, LDH levels and FACIT- Fatigue Score; number of PRBC (packed red blood cell) units transfused from week 4 to 16 and hemoglobin response in the absence of transfusions, and reticulocyte normalization in the absence of transfusion at week 16.
To date, subcutaneous APL-2 has generally been well-tolerated with cumulative systemic exposure of over 12 patient years of treatment on APL-2. No significant infections or thromboembolic events have been observed.
“The initiation of the first of our two Phase 3 trials for patients with PNH is a significant milestone for Apellis as we continue to advance the development of APL-2 for this indication,” said Dr. Cedric Francois, MD, PhD, Apellis co-founder and CEO. “We believe there’s an unmet medical need to bring patients with PNH a better treatment option that will provide broad hematological correction and better quality of life than the current standard of care.”
About Paroxysmal Nocturnal Hemoglobinuria
Paroxysmal nocturnal hemoglobinuria (PNH) is a rare, acquired, potentially life-threatening disease characterized by complement-mediated hemolysis with or without hemoglobinuria, an increased susceptibility to thrombotic episodes and/or some degree of bone marrow dysfunction. A significant subset of patients treated with the current standard of care still suffer from debilitating anemia and transfusion dependence.
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). In addition to the PEGASUS trial, Apellis is currently evaluating APL-2 in two Phase 1b clinical trials for systemic administration in paroxysmal nocturnal hemoglobinuria (the PHAROAH trial and the PADDOCK trial). 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 1b/2 clinical trial evaluating intravitreal APL-2 in wet age-related macular degeneration. Phase 3 studies are planned in intravitreal APL-2 for geographic atrophy (GA) and PNH. Future clinical studies of APL-2 are anticipated in other diseases in which complement is implicated.
