Apellis Pharmaceuticals Reports Third Quarter 2021 Financial Results

• Generated $5.3 million in EMPAVELI™ (pegcetacoplan) net product revenues
• Presented Phase 3 DERBY and OAKS results in geographic atrophy (GA); on track for NDA submission in 1H 2022
• Received positive CHMP opinion for pegcetacoplan for treatment of PNH; expect decision regarding approval by European Commission by end of 2021
• Conference call scheduled today at 4:30 p.m. ET

WALTHAM, Mass., Nov. 08, 2021 (GLOBE NEWSWIRE) -- Apellis Pharmaceuticals, Inc. (Nasdaq: APLS), a global biopharmaceutical company and leader in complement, today announced its third quarter 2021 financial results and business highlights.

“The third quarter was another exceptional period for Apellis, highlighted by successful commercial execution with EMPAVELI in PNH, the Phase 3 DERBY and OAKS results in geographic atrophy, and continued momentum advancing our broader pipeline,” said Cedric Francois, M.D., Ph.D., co-founder and chief executive officer of Apellis. “Our commercial launch of EMPAVELI is off to a strong start in the U.S. and we expect a decision regarding approval by the European Commission by the end of this year as we seek to elevate the standard of care in PNH worldwide.”

Dr. Francois continued, “With the DERBY and OAKS data, intravitreal pegcetacoplan has the potential to become the first treatment for patients living with geographic atrophy, a leading cause of blindness worldwide. We believe we have a robust data package that supports approval and remain on track to submit our New Drug Application to the FDA in the first half of 2022. Behind our lead programs, we are continuing to progress our broad pipeline addressing complement-driven diseases in rare disease, neurology, and ophthalmology.”

Third Quarter 2021 Business Highlights and Upcoming Milestones:

Paroxysmal Nocturnal Hemoglobinuria (PNH) Commercial Progress

• Apellis recorded $5.3 million in EMPAVELI™ (pegcetacoplan) net product revenue for the third quarter of 2021.
• In October 2021, Apellis and Sobi announced that the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) had adopted a positive opinion recommending the marketing authorization of systemic pegcetacoplan for the treatment of adults with PNH who are anemic after treatment with a C5 inhibitor for at least three months.
  • A decision regarding approval is expected by the European Commission by the end of 2021.
  • Apellis is eligible for a $50.0 million milestone payment from Sobi upon first regulatory and reimbursement approval. If systemic pegcetacoplan is approved by the EMA in 2021, Apellis expects to achieve this milestone in the first half of 2022.

Rare Disease R&D Highlights

• Immune complex membranoproliferative glomerulonephritis (IC-MPGN) and C3 glomerulopathy (C3G): Apellis expects to initiate a Phase 3 study in the fourth quarter of 2021.
• Cold agglutinin disease (CAD): Sobi plans to initiate a Phase 3 study in the fourth quarter of 2021.
• Hematopoietic stem cell transplantation-associated thrombotic microangiopathy (HSCT-TMA): Sobi plans to initiate a potentially registrational program in the fourth quarter of 2021.
• Amyotrophic lateral sclerosis (ALS): Apellis now expects to complete enrollment for its ongoing and potentially registrational Phase 2 MERIDIAN study in the first half of 2022 (previously end of 2021). Enrollment is slower than expected due to the COVID-19 pandemic and competing ongoing trials recruiting in ALS.
• EMPAVELI + small interfering RNA (siRNA): Apellis plans to study the combination of EMPAVELI and an siRNA, which may offer the potential to reduce the treatment frequency of EMPAVELI. Apellis expects to submit an Investigational New Drug (IND) application in the first half of 2023.
  

Ophthalmology R&D Highlights

• Geographic atrophy:
  • In September 2021, Apellis reported top-line results from the Phase 3 DERBY and OAKS studies evaluating intravitreal pegcetacoplan, an investigational targeted C3 therapy, in 1,258 adults with geographic atrophy (GA) secondary to age-related macular degeneration (AMD).
    • OAKS met the primary endpoint for both monthly and every-other-month treatment with pegcetacoplan, demonstrating a significant reduction in GA lesion growth of 22% (p=0.0003) and 16% (p=0.0052), respectively, compared to pooled sham at 12 months.
    • DERBY narrowly missed the primary endpoint of GA lesion growth, showing a reduction of 12% (p=0.0528) and 11% (p=0.0750) with monthly and every-other-month treatment, respectively, compared to pooled sham at 12 months.
    • In a prespecified analysis of the combined studies, pegcetacoplan decreased GA lesion growth in patients with extrafoveal lesions at baseline by 26% (p<0.0001) and 23% (p=0.0002) with monthly and every-other-month treatment, respectively.
    • Pegcetacoplan demonstrated a favorable safety profile in both Phase 3 studies. 
  • Detailed data from the DERBY and OAKS studies were presented for the first time as part of two presentations at the Retina Society Annual Scientific Meeting in September 2021. This was followed by two additional presentations at The American Society of Retina Specialists Annual Meeting in September 2021. Copies of the presentations can be found on the Investors section of the Apellis website.
  • The company plans to submit a New Drug Application (NDA) for pegcetacoplan for GA to the U.S. Food and Drug Administration (FDA) in the first half of 2022.
• Intermediate AMD: Apellis plans to initiate a pivotal Phase 3 trial for pegcetacoplan in intermediate AMD in 2022, pending regulatory feedback.
• APL-2006: Apellis expects to submit an IND for APL-2006, a bispecific C3 and VEGF inhibitor, in the first half of 2023.

Neurology R&D Highlights

• APL-1030: Apellis expects to submit an IND for APL-1030, a first-in-class, brain-active C3 inhibitor for neurodegenerative diseases, in the second half of 2022.
  

Third Quarter 2021 Financial Results:

Cash. As of September 30, 2021, Apellis had $430.3 million in cash, cash equivalents, and short-term marketable securities, compared to $877.6 million in cash, cash equivalents, and short-term marketable securities as of December 31, 2020. Cash used during the period included the $50.0 million payment associated with the Beam collaboration.

Total Revenue. Total revenue was $5.7 million for the third quarter of 2021, which consisted of $5.3 million in recorded net product sales of EMPAVELI in the U.S. and $0.4 million in revenue associated with the Sobi collaboration. Apellis recorded $0.6 million in licensing revenue during the quarter ended September 30, 2020.

Research and Development (R&D) Expenses. R&D expenses were $87.7 million for the third quarter of 2021, compared to $93.2 million for the same period in 2020. The decrease in R&D expense for the third quarter of 2021 was primarily attributable to a decrease in contract manufacturing expenses due to the timing of drug supply and analytical activity, a decrease in the capitalization of inventory following FDA approval of EMPAVELI, and an increase in contra R&D expense related to the Sobi transaction. These amounts were offset by an increase in personnel related costs primarily due to the hiring of additional personnel, an increase in regulatory, quality and medical affairs expenses, and an increase in pre-clinical and clinical development costs.

General and Administrative (G&A) Expenses. G&A expenses were $45.8 million in the third quarter of 2021, compared to $37.0 million for the same period in 2020. The increase in G&A expenses for the third quarter of 2021 was primarily attributable to an increase in employee related costs, general commercial preparation activities, director stock compensation expense, and general office and travel related costs.

Net Loss. Apellis reported a net loss of $195.6 million for the third quarter of 2021, compared to a net loss of $135.7 million for the same period in 2020.

About EMPAVELI™ (pegcetacoplan)

EMPAVELI™ (pegcetacoplan) is the first and only approved therapy targeting C3, the central protein in the complement cascade. EMPAVELI acts proximally in the complement cascade controlling both C3b-mediated extravascular hemolysis and terminal complement-mediated intravascular hemolysis. EMPAVELI is approved in the United States for the treatment of adults with paroxysmal nocturnal hemoglobinuria (PNH).

U.S. Important Safety Information for EMPAVELI

BOXED WARNING: SERIOUS INFECTIONS CAUSED BY ENCAPSULATED BACTERIA

• Meningococcal infections may occur in patients treated with EMPAVELI and may become rapidly life-threatening or fatal if not recognized and treated early. Use of EMPAVELI may predispose individuals to serious infections, especially those caused by encapsulated bacteria, such as Streptococcus pneumoniae, Neisseria meningitidis types A, C, W, Y, and B, and Haemophilus influenzae type B.
• Comply with the most current Advisory Committee on Immunization Practices (ACIP) recommendations for vaccinations against encapsulated bacteria.
• Vaccinate patients at least 2 weeks prior to administering the first dose of EMPAVELI unless the risks of delaying therapy with EMPAVELI outweigh the risk of developing a serious infection.
• Vaccination reduces, but does not eliminate, the risk of serious infections. Monitor patients for early signs of serious infections and evaluate immediately if infection is suspected.
• EMPAVELI is available only through a restricted program under a Risk Evaluation and Mitigation Strategy (REMS). Under the EMPAVELI REMS, prescribers must enroll in the program.
  

CONTRAINDICATIONS

• Hypersensitivity to pegcetacoplan or to any of the excipients
• Not currently vaccinated against certain encapsulated bacteria, unless the risks of delaying EMPAVELI treatment outweigh the risks of developing a bacterial infection with an encapsulated organism
• Unresolved serious infection caused by encapsulated bacteria including Streptococcus pneumoniae, Neisseria meningitidis, and Haemophilus influenzae
  

WARNINGS AND PRECAUTIONS

Serious Infections Caused by Encapsulated Bacteria
The use of EMPAVELI may predispose individuals to serious, life-threatening, or fatal infections caused by encapsulated bacteria, including Streptococcus pneumoniae, Neisseria meningitidis types A, C, W, Y, and B, and Haemophilus influenzae type B (Hib). To reduce the risk of infection, all patients must be vaccinated against these bacteria according to the most current ACIP recommendations for patients with altered immunocompetence associated with complement deficiencies. Revaccinate patients in accordance with ACIP recommendations considering the duration of therapy with EMPAVELI.

For patients without known history of vaccination, administer required vaccines at least 2 weeks prior to receiving the first dose of EMPAVELI. If immediate therapy with EMPAVELI is indicated, administer required vaccine as soon as possible and provide patients with 2 weeks of antibacterial drug prophylaxis.

Closely monitor patients for early signs and symptoms of serious infection and evaluate patients immediately if an infection is suspected. Promptly treat known infections. Serious infection may become rapidly life-threatening or fatal if not recognized and treated early. Consider discontinuation of EMPAVELI in patients who are undergoing treatment for serious infections.

EMPAVELI REMS
Because of the risk of serious infections, EMPAVELI is available only through a restricted program under a REMS. Under the EMPAVELI REMS, prescribers must enroll in the program and must counsel patients about the risk of serious infection, provide the patients with the REMS educational materials, and ensure patients are vaccinated against encapsulated bacteria. Enrollment and additional information are available by telephone: 1-888-343-7073 or at www.empavelirems.com.

Infusion-Related Reactions
Systemic hypersensitivity reactions (e.g., facial swelling, rash, urticaria) have occurred in patients treated with EMPAVELI. One patient (less than 1% in clinical studies) experienced a serious allergic reaction which resolved after treatment with antihistamines. If a severe hypersensitivity reaction (including anaphylaxis) occurs, discontinue EMPAVELI infusion immediately, institute appropriate treatment, per standard of care, and monitor until signs and symptoms are resolved.

Monitoring PNH Manifestations after Discontinuation of EMPAVELI
After discontinuing treatment with EMPAVELI, closely monitor for signs and symptoms of hemolysis, identified by elevated LDH levels along with sudden decrease in PNH clone size or hemoglobin, or reappearance of symptoms such as fatigue, hemoglobinuria, abdominal pain, dyspnea, major adverse vascular events (including thrombosis), dysphagia, or erectile dysfunction. Monitor any patient who discontinues EMPAVELI for at least 8 weeks to detect hemolysis and other reactions. If hemolysis, including elevated LDH, occurs after discontinuation of EMPAVELI, consider restarting treatment with EMPAVELI.

Interference with Laboratory Tests
There may be interference between silica reagents in coagulation panels and EMPAVELI that results in artificially prolonged activated partial thromboplastin time (aPTT); therefore, avoid the use of silica reagents in coagulation panels.

ADVERSE REACTIONS
The most common adverse reactions (incidence ≥10% of patients) with EMPAVELI vs. eculizumab were injection-site reactions (39% v. 5%), infections (29% v. 26%), diarrhea (22% v. 3%), abdominal pain (20% v. 10%), respiratory tract infection (15% v. 13%), viral infection (12% v. 8%), and fatigue (12% v. 23%).

USE IN SPECIFIC POPULATIONS

Females of Reproductive Potential
EMPAVELI may cause embryo-fetal harm when administered to pregnant women. Pregnancy testing is recommended for females of reproductive potential prior to treatment with EMPAVELI. Advise female patients of reproductive potential to use effective contraception during treatment with EMPAVELI and for 40 days after the last dose.

Please see full Prescribing Information, including Boxed WARNING regarding serious infections caused by encapsulated bacteria, and Medication Guide.
