-- Phase 3 DERBY and OAKS Trials Evaluating Pegcetacoplan in Geographic Atrophy (GA) Fully Enrolled; Top-line Data Expected in the Third Quarter of 2021

-- PRINCE Trial Evaluating Pegcetacoplan in Treatment-Nave PNH Patients Fully Enrolled; Top-line Data Expected in the First Half of 2021

-- Cash and Investments of $833 Million as of June 30, 2020

WALTHAM, Mass., July 31, 2020 (GLOBE NEWSWIRE) -- Apellis Pharmaceuticals,Inc. (Nasdaq: APLS), a global biopharmaceutical company and leader in targeted C3 therapies, today announced its second quarter 2020 financial results and business highlights.

This past quarter, Apellis continued to make remarkable progress advancing our targeted C3 therapy, pegcetacoplan, for patients living with serious, complement-driven diseases, said Cedric Francois, M.D., Ph.D., co-founder and chief executive officer of Apellis. In PNH, we presented detailed results from the Phase 3 PEGASUS study, which showed that pegcetacoplan demonstrated substantial improvements over C5 inhibition and strengthened our belief in the potential of targeting C3 to elevate the standard of care in PNH. Following positive meetings with regulatory agencies, we are on track to submit marketing applications to the FDA and EMA later this year, and we look forward to bringing pegcetacoplan to the PNH community.

We also completed enrollment in three Phase 3 trials while ensuring patient safety during the pandemic. These included two pivotal trials in geographic atrophy, a leading cause of blindness that affects five million people worldwide and has no approved treatment. We look forward to top-line results from these studies, as well as from our Phase 3 PRINCE trial in treatment-nave patients with PNH, in 2021. I am proud of all that the Apellis team continues to accomplish to bring life-changing therapies to people with debilitating diseases. Business Highlights and Upcoming Milestones

Subcutaneous Pegcetacoplan (APL-2)

-- In July 2020, Apellis announced the completion of enrollment in the global Phase 3 PRINCE study, which is evaluating pegcetacoplan in patients with PNH who are treatment-nave, meaning they had not received a complement inhibitor within three months before entering the trial. The company expects to report top-line results in the first half of 2021. -- In June 2020, Apellispresented detailed results from the Phase 3 PEGASUS study in an oral presentation at the 25thCongress of the European Hematology Association (EHA). New data from the pivotal study showed that the benefit of pegcetacoplan treatment was consistent across the study population, both in patients who had low or no transfusion requirements and high transfusion requirements. Pegcetacoplan also demonstrated higher normalization rates in key markers of hemolysis and clinically meaningful improvements in FACIT-fatigue score compared to eculizumab at 16 weeks. -- Apellis plans to submit an NDA to the U.S. Food and Drug Administration (FDA) and a MAA to the European Medicines Agency (EMA) for pegcetacoplan for the treatment of PNH in the second half of the year. -- The company also expects to report 48-week top-line results from the PEGASUS trial by the end of the year. -- Apellis plans to disclose the strategy and timing for further clinical development of pegcetacoplan for patients with cold agglutinin disease (CAD) and C3 glomerulopathy (C3G) in the third quarter.

Intravitreal Pegcetacoplan

-- In July 2020, Apellis announced that it completed enrollment in the Phase 3 DERBY and OAKS studies investigating intravitreal pegcetacoplan for the treatment of GA secondary to age-related macular degeneration (AMD). The company expects to announce top-line results from both trials in the third quarter of 2021.

COVID-19 Clinical Program

-- In May 2020, Apellis announced that it had initiated a Phase 1/2 clinical study of APL-9 in COVID-19 patients with respiratory failure including acute respiratory distress syndrome. An independent data monitoring committee (DMC) reviewed safety data from the first six patients who received open-label APL-9 and recommended that the study continue. Apellis is now enrolling an additional 60 patients into the randomized, double-blind, controlled part of the study.

Corporate & Other Highlights:

-- In May 2020, Apellis announced it had entered into subscription agreements with a number of institutional investors for a private placement of $300.0 million aggregate principal amount of 3.500% convertible senior notes due in 2026, for an aggregate purchase price of $328.9 million.

Second Quarter 2020 Financial Results:

As of June 30, 2020, Apellis had $833 million in cash, cash equivalents, and short-term marketable securities, compared to $352 million in cash and cash equivalents as of December 31, 2019.

Apellis reported a net loss of $118.6 million for the second quarter of 2020, compared to a net loss of $71.1 million for the second quarter of 2019.

Research and development expenses were $87.1 million in the second quarter of 2020, compared to $50.7million for the same period in 2019. The increase was primarily attributable to an increase of $8.8 million in contract manufacturing expenses in connection with the supply of pegcetacoplan for our Phase 3 clinical trials, an increase of $6.7 million in clinical trial costs associated with the continued enrollment of our Phase 3 clinical trials in PNH and GA, an increase of $11.0 million in personnel-related costs primarily due to the hiring of additional personnel, an increase of $4.6 million related to research and innovation activities, and an increase of $6.2 million in other development costs, and offset by a decrease of $0.9 million in pre-clinical study expenses and device development expenses. We would expect our research and development expenses to continue to increase with the number of aggregate patients enrolled in our trials and as we may add to the number of ongoing trials for subcutaneous pegcetacoplan.

General and administrative expenses were $28.4 million in the second quarter of 2020, compared to $12.8 million for the same period in 2019. The increase was primarily attributable to an increase in employee-related costs of $9.9 million, an increase in professional and consulting fees and general commercial preparation activities of $5.7 million, an increase of $0.4 million in director stock compensation expense, and an increase in $0.3 million in insurance, offset by a decrease in general office costs and conference and travel-related expenses of $0.7 million. The increase in employee-related costs of $9.9 million consisted of a $6.1 million increase in salaries and benefits primarily due to the increase in the number of employees, $3.6 million related to stock expense associated with the grant of stock options and restricted stock units to employees, and $0.2 million in recruitment expense. The increase in other professional and consulting fees and general commercial preparation activities of $5.7 million primarily related to an increase in commercial-related activity of $4.8 million, an increase of $0.9 million in general consulting fees, a $0.3 million increase in accounting, an increase in communication and public relations fees of $0.1 million, and offset by a decrease of $0.4 million legal fees.

About Pegcetacoplan (APL-2)Pegcetacoplan is the only investigational targeted C3 therapy in late-stage clinical trials. It is designed to control excessive or uncontrolled complement activation, which can lead to the onset and progression of many serious diseases. Pegcetacoplan is a synthetic cyclic peptide conjugated to a polyethylene glycol polymer that binds specifically to C3 and C3b.Apellis is evaluating pegcetacoplan in several clinical studies including geographic atrophy (GA), paroxysmal nocturnal hemoglobinuria (PNH), cold agglutinin disease, and C3 glomerulopathy. Pegcetacoplan was granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment of GA and the treatment of PNH.

About APL-9APL-9 is an investigational drug designed to control the complement cascade centrally at C3 and may have the potential to treat a range of diseases caused by excessive or uncontrolled activation of complement.

APL-9 is designed to be intravenously administered for acute use.
