Business Highlights and Upcoming Milestones:

Systemic Pegcetacoplan (APL-2)

• In October 2020, Apellis announced a strategic collaboration with Swedish Orphan Biovitrum AB (publ) (Sobi) for the global co-development and exclusive ex-U.S. commercialization rights for systemic pegcetacoplan. Apellis retains U.S. commercialization rights for systemic pegcetacoplan and worldwide commercial rights for intravitreal pegcetacoplan. Under the terms of the agreement, Sobi will make an upfront payment to Apellis of $250 million and up to $915 million in other regulatory and commercial milestone payments and will contribute $80 million in committed reimbursement payments over a four-year period for research and development. Apellis will also be eligible for tiered double-digit royalties on sales ranging from high teens to high twenties. As part of the collaboration, the companies plan to start two new registrational programs in cold agglutinin disease (CAD) and hematopoietic stem cell transplantation-associated thrombotic microangiopathy (HSCT-TMA) in 2021.
• In October 2020, Apellis presented 48-week data from the Phase 2 DISCOVERY study of pegcetacoplan in patients with C3G at the American Society of Nephrology (ASN) Kidney Week 2020. At week 48, pegcetacoplan demonstrated sustained improvements across key clinical measures including a 73.3% reduction in mean proteinuria, an important marker of kidney damage. No serious or severe adverse events were reported, and pegcetacoplan was well tolerated overall.
• In October 2020, Apellis announced the initiation of registrational programs of pegcetacoplan in patients with immune complex membranoproliferative glomerulonephritis (IC-MPGN) or C3G and in patients with amyotrophic lateral sclerosis (ALS). The IC-MPGN / C3G registrational program consists of the recently initiated Phase 2 NOBLE study focused on the histopathology of the kidneys and a Phase 3 study that is expected to begin in the first half of 2021. The company expects the first patient to be dosed in the potentially registrational Phase 2 MERIDIAN study in ALS, Apellis' first neurological program, by the end of 2020.
• In September 2020, Apellis announced the submission of an NDA to the U.S. Food and Drug Administration (FDA) and an MAA to the European Medicines Agency (EMA) for pegcetacoplan for the treatment of paroxysmal nocturnal hemoglobinuria (PNH). The EMA validated the MAA in October 2020, and an opinion from the Committee for Medicinal Products for Human Use (CHMP) is expected in 2021. The FDA's decision on acceptance of the NDA and guidance on a potential Prescription Drug User Fee Act (PDUFA) target action date is expected in the fourth quarter of 2020. In October, Apellis submitted a marketing application for pegcetacoplan in PNH to the Australian Therapeutic Goods Administration (TGA). The TGA granted orphan drug designation to pegcetacoplan in PNH in September.
• The company expects to report 48-week top-line results from the PEGASUS study by the end of the year and top-line results from the Phase 3 PRINCE study in patients with PNH who are treatment-naïve in the first half of 2021.
  

Intravitreal Pegcetacoplan

• In October 2020, Apellis announced 18-month data from the Phase 1b study of intravitreal pegcetacoplan in patients with advanced geographic atrophy (GA) and low vision. Data from a post hoc analysis demonstrated a 52% decrease in the growth rate of GA lesions in the treated eye compared to the untreated eye in seven patients with bilateral GA (disease in both eyes) at 18 months (p=0.01).
• In October 2020, Apellis presented results of a post hoc analysis of the Phase 2 FILLY study at a late-breaking oral session at the European Society of Retina Specialists (EURETINA) 2020 Virtual Meeting. The data showed a 39% reduction in the rate of progression from nascent GA, an earlier form of disease, to GA in patients treated with pegcetacoplan monthly versus sham injections, demonstrating that intravitreal pegcetacoplan may slow early disease progression.
• The company expects to announce top-line results from the Phase 3 DERBY and OAKS studies in the third quarter of 2021.
  

COVID-19 Clinical Program

• In October 2020, the company announced preliminary results from a Phase 1/2 clinical study of APL-9, a targeted C3 therapy designed for acute conditions, in patients with severe COVID-19. Preliminary open-label safety data from six patients with respiratory failure, including acute respiratory distress syndrome, supported advancement of the study. Apellis is currently enrolling an additional 60 patients into the randomized, double-blind, controlled phase of the study.
• The company also announced data from an observational study in 41 patients hospitalized with COVID-19, which showed a correlation between increased complement activation and disease severity, supporting further evaluation of targeted C3 therapies for treating severe COVID-19.

Third Quarter 2020 Financial Results:

As of September 30, 2020, Apellis had $728.2 million in cash, cash equivalents, and short-term marketable securities, compared to $352 million in cash and cash equivalents as of December 31, 2019. This does not include the $250 million upfront proceeds from the Sobi transaction that was announced on October 27, 2020.

Apellis reported a net loss of $135.7 million for the third quarter of 2020, compared to a net loss of $69.8 million for the third quarter of 2019.

Research and development expenses were $93.2 million in the third quarter of 2020, compared to $51.3 million for the same period in 2019. The increase was primarily attributable to an increase of $18.0 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 $9.9 million in personnel-related costs primarily due to the hiring of additional personnel, an increase of $7.8 million related to research and innovation activities and other development costs and offset by a decrease of $0.5 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 systemic pegcetacoplan.

General and administrative expenses were $37.0 million in the third quarter of 2020, compared to $18.6 million for the same period in 2019. The increase was primarily attributable to an increase in employee-related costs of $8.2 million, an increase in professional and consulting fees and general commercial preparation activities of $9.7 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 $0.2 million. The increase in employee-related costs of $8.2 million consisted of a $5.7 million increase in salaries and benefits primarily due to the increase in the number of employees, $3.5 million related to stock expense associated with the grant of stock options and restricted stock units to employees offset by a decrease of $1.0 million in recruitment expense. The increase in other professional and consulting fees and general commercial preparation activities of $9.7 million primarily related to an increase in commercial-related activity of $6.3 million, a $2.6 million increase in legal and accounting fees, and an increase in general professional fees of $0.7 million and an increase in communication and public relations fees of $0.1 million.

About Pegcetacoplan (APL-2)
Pegcetacoplan is an investigational, targeted C3 therapy designed to regulate excessive activation of the complement cascade, part of the body's immune system, 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 across hematology, ophthalmology, nephrology, and neurology. Pegcetacoplan was granted Fast Track designation by the U.S. Food and Drug Administration (FDA) for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) and the treatment of geographic atrophy, and received orphan drug designation for the treatment of C3 glomerulopathy (C3G) by the FDA and European Medicines Agency.
