WALTHAM, Mass., Aug. 08, 2022 (GLOBE NEWSWIRE) -- Apellis Pharmaceuticals, Inc. (Nasdaq: APLS), a global biopharmaceutical company and leader in complement, today announced its second quarter 2022 financial results and business highlights.

“2022 is a transformational year for Apellis, and we have made great progress across the company in the first half. Starting with geographic atrophy, our NDA with intravitreal pegcetacoplan was recently accepted with priority review designation, putting us on track for an approval decision in November. This is our second NDA acceptance in less than two years, a monumental accomplishment for the team,” said Cedric Francois, M.D., Ph.D., co-founder and chief executive officer of Apellis. “Geographic atrophy is a devastating disease that leads to irreversible blindness and, if approved, pegcetacoplan will be the first and only treatment available. We continue to work closely with the FDA to bring this treatment to patients as quickly as possible.”

Dr. Francois continued, “Additionally, we passed our first full year on the U.S. market with EMPAVELI for PNH and it is continuing to show impressive commercial momentum. Beyond PNH, we are advancing the broad platform potential of EMPAVELI with four late-stage clinical programs now underway, as well as our research programs with new molecules that we continue to advance towards IND submissions.”

Second Quarter 2022 Business Highlights and Upcoming Milestones:

Paroxysmal Nocturnal Hemoglobinuria (PNH) Commercial Progress

• Apellis recorded $15.7 million in EMPAVELI® (pegcetacoplan) U.S. net product revenues.
• Apellis presented new data at the European Hematology Association (EHA) Congress reinforcing the robust clinical, safety and health-related quality of life outcomes for PNH patients treated with EMPAVELI.
• Apellis was recognized as a 2022 Industry Innovation Award honoree for EMPAVELI in PNH by the National Organization for Rare Disorders (NORD) at the Rare Impact Award Ceremony
• Sobi submitted and received acceptance for a Japanese regulatory submission for a potential indication in PNH.

Rare Disease R&D Highlights

• Immune complex membranoproliferative glomerulonephritis (IC-MPGN) and C3 glomerulopathy (C3G): Apellis dosed the first patient in the Phase 3 VALIANT study of systemic pegcetacoplan for IC-MPGN and C3G in the second quarter of 2022.  
  • Apellis was granted Orphan Drug Designation (ODD) by the U.S. FDA for pegcetacoplan for the treatment for IC-MPGN. Apellis was previously granted ODD for pegcetacoplan for the treatment of C3G in 2018.
• Cold agglutinin disease (CAD): Sobi now expects to dose the first patient in the Phase 3 study of systemic pegcetacoplan for CAD in the second half of 2022.
• Amyotrophic lateral sclerosis (ALS): Apellis completed enrollment in its ongoing and potentially registrational Phase 2 MERIDIAN study with systemic pegcetacoplan for ALS in the first quarter of 2022. Top-line results are expected in mid-2023.

Second Quarter 2022 Financial Results:

Cash. As of June 30, 2022, Apellis had $852.8 million in cash, cash equivalents, and short-term marketable securities, compared to $599.0 million in cash, cash equivalents, and short-term marketable securities as of June 30, 2021.

Total Revenue. Total revenue was $16.3 million for the second quarter of 2022, which consisted of $15.7 million in net product revenue from sales of EMPAVELI and $0.6 million in revenue associated with the Sobi collaboration.

Research and Development (R&D) Expenses.

• R&D expenses were $101.7 million for the second quarter of 2022, compared to $145.9 million for the same period in 2021.
• The decrease in R&D expenses for the second quarter ended June 30, 2022 was primarily attributable to the $50.0 million cost of research collaboration associated with the Beam arrangement recorded in the second quarter of 2021, combined with a decrease in contract manufacturing expenses, clinical trial costs, research and innovation costs and pre-clinical study expenses. These decreases were offset by an increase in personnel related costs due to having more employees in the three months ended June 30, 2022, decreases in contra research and development expense related to the Sobi transaction, and an increase in other research and development supporting activities primarily driven by regulatory, quality and medical affairs expenses.

General and Administrative (G&A) Expenses.

• G&A expenses were $63.2 million for the second quarter of 2022, compared to $49.0 million for the same period in 2021.
• The increase in G&A expenses for the second quarter ended June 30, 2022 was primarily attributable to increases in employee-related costs, professional and consulting fees and general commercial preparation activities.

Net Loss (Income). Apellis reported a net loss of $156.0 million in the second quarter 2022, compared to a net loss of $219.2 million for the same period in 2021.

Convertible Notes. As of June 30, 2022, the aggregate principal balance of the 3.500% Convertible Senior Notes (Notes) due 2026, net of unamortized debt issuance costs, was $189.3 million.

About EMPAVELI®/Aspaveli® (pegcetacoplan)EMPAVELI®/Aspaveli® (pegcetacoplan) is a 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. EMPAVELI is approved for the treatment of paroxysmal nocturnal hemoglobinuria (PNH) in the United States, Australia, and Saudi Arabia, and Aspaveli, which is the European trade name for pegcetacoplan, is approved in the European Union and Great Britain. The therapy is also under investigation for several other rare diseases across hematology, nephrology, and neurology.

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 BacteriaThe 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 REMSBecause 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 ReactionsSystemic 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 EMPAVELIAfter 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 TestsThere 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 REACTIONSThe 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 PotentialEMPAVELI 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.
