Apellis Pharmaceuticals’ APL-2 Receives Fast Track Designation from FDA for the Treatment of Patients with Geographic Atrophy
July 24, 2018
CRESTWOOD, Ky., and WALTHAM Mass. -- 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 the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to the Company’s APL-2, a novel inhibitor of complement factor C3 as a next generation monotherapy, for the treatment of patients with geographic atrophy (GA), an advanced form of age-related macular degeneration.
The FDA’s Fast Track program facilitates the development and expedites the review of drugs to treat serious conditions and fill an unmet medical need, allowing important new drugs to reach the patient earlier. Filling an unmet medical need is defined as providing a therapy where none exists or providing a therapy which may have potential benefits over existing therapies. Drugs that receive a Fast Track designation are eligible for more frequent meetings and written communication with the FDA to discuss development plans and clinical trial design. In addition, if criteria are met, Fast Track-designated drugs are eligible for Rolling Review, where a drug company can separately submit sections of its New Drug Application to the FDA, and Accelerated Approval and Priority Review, in which drugs for serious conditions fulfilling an unmet medical need can be approved based on a surrogate endpoint.
“The Fast Track designation represents an important recognition by the FDA of APL-2’s potential to treat geographic atrophy, a blinding disease for which there is no treatment,” commented Cedric Francois, MD, PhD, founder and chief executive officer of Apellis. “The severe vision loss associated with GA makes it difficult for patients to recognize faces, read, drive a car and go about their daily lives, limiting quality of life. We believe that by slowing down the rate of degeneration through broad C3 inhibition, we may be able to improve outcomes for these patients.”
Apellis plans to initiate a Phase 3 trial for patients with GA later this year which will consist of two identical, prospective, multicenter, randomized, double-masked, sham-injection controlled studies to assess the efficacy and safety of multiple intravitreal (IVT) injections of APL-2 in patients with GA.
About the FILLY trial
The FILLY trial is a 246-patient Phase 2 multicenter, randomized, single-masked, sham-controlled clinical trial of APL-2 in patients with GA conducted at over 40 clinical sites, located in the United States, Australia and New Zealand. APL-2 was administered as an intravitreal injection in the study eye monthly or every other month for 12 months, followed by six months of monitoring without active treatment until month 18. Eyes were evaluated for GA by fundus autofluorescence photographs (FAF). The rate of GA area growth was measured from baseline to month 18. The primary efficacy endpoint was the change in GA lesion size from baseline to month 12, compared to sham.
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 FILLY trial in GA, Apellis is currently evaluating APL-2 in two clinical trials for systemic administration in paroxysmal nocturnal hemoglobinuria (PNH). Interim data from these trials demonstrated meaningful improvements in lactate dehydrogenase and hemoglobin levels in previously untreated patients as well as patients who are suboptimal responders to eculizumab, the current standard of care in the treatment of PNH. PNH Phase 3 study, PEGASUS commenced in June and a Phase 3 in GA in anticipated later this year.
About geographic atrophy (GA)
GA is an advanced form of age-related macular degeneration (AMD), a disorder of the central portion of the retina, known as the macula, which is responsible for central vision and color perception. GA is a chronic, progressive condition that leads to central blind spots and permanent loss of vision. Based on published studies, we estimate that approximately one million people have GA in the United States alone. There are currently no approved treatments for GA.
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 our clinical trials visit www.apellis.com/clinical-trials.html.
