• APL-1030: Apellis continues to advance pre-clinical studies with APL-1030, a first-in-class, brain-active C3 inhibitor for neurological diseases.
  

Fourth Quarter and Full Year 2022 Financial Results:

Cash. As of December 31, 2022, Apellis had $551.8 million in cash and cash equivalents, compared to $700.6 million in cash, cash equivalents, and short-term marketable securities as of December 31, 2021.

Total Revenue.

• Total revenue was $22.7 million for the fourth quarter of 2022, which consisted of $19.7 million of U.S. net product revenue of EMPAVELI and additional licensing and other revenue associated with the Sobi collaboration. Total revenue was $60.3 million for the fourth quarter of 2021, which consisted of $9.2 million in U.S. net product revenue of EMPAVELI and $51.1 million in revenue associated with the $50.0 milestone and additional licensing and other revenue from the Sobi collaboration.
• For the full year 2022, total revenue was $75.4 million, which consisted of $65.1 million of U.S. net product revenue of EMPAVELI and additional licensing and other revenue associated with the Sobi collaboration. For the full year 2021, total revenue was $66.6 million, which consisted of $15.1 million in U.S. net product revenue of EMPAVELI and $51.4 million in revenue associated with the $50.0 milestone and additional licensing and other revenue from the Sobi collaboration.

Cost of Sales.

• Cost of sales were $5.6 million and $0.2 million for the full year 2022 and 2021, respectively. Cost of sales consists primarily of costs associated with the manufacturing of EMPAVELI, royalties owed to our licensor for such sales, and certain period costs.
  • Prior to receiving FDA approval for EMPAVELI in May 2021, costs associated with the manufacturing of EMPAVELI inventory were expensed as research and development (R&D) expense. This resulted in inventory being sold during the years ended December 31, 2022 and 2021 for which a portion of the costs had been previously expensed prior to FDA approval.

R&D Expenses.

• R&D expenses were $99.4 million for the fourth quarter of 2022, compared to $108.2 million for the same period in 2021. For the full year ended December 31, 2022, R&D expenses were $387.2 million compared to $425.9 million for the full year ended December 31, 2021.
• The decrease in R&D expenses for the full year ended December 31, 2022 was primarily attributable to $75.0 million associated with the Beam collaboration and the $5.0 million licensee fee to the University of Pennsylvania related to the Sobi transaction recorded in 2021, a decrease in clinical contract manufacturing expenses due primarily to the timing of drug supply and analytical activity, and a decrease in clinical trial costs due to the completion of our Phase 3 OAKS and DERBY trials. These decreases were offset by higher personnel related costs due to having more employees as of December 31, 2022, higher research and innovation costs, and higher other research and development supporting activities. In addition, contra research and development expenses under the Sobi collaboration were $5.0 million for the year ended December 31, 2022 compared to $32.0 million for the year ended December 31, 2021.

General and Administrative (G&A) Expenses.

• G&A expenses were $84.4 million for the fourth quarter of 2022, compared to $41.5 million for the same period in 2021. For the full year ended December 31, 2022, G&A expenses were $277.2 million compared to $176.8 million for the full year ended December 31, 2021.
• The increase in G&A expenses for the full year ended December 31, 2022 was primarily attributable to an increase in employee related costs and increases in costs related to general commercial preparation activities.

Net Loss (Income). Apellis reported a net loss of $166.0 million and $652.2 million for the fourth quarter and full year 2022, respectively, compared to a net loss of $147.9 million and $746.4 million for the same periods in 2021.

U.S. Important Safety Information for SYFOVRE™ (pegcetacoplan injection)
CONTRAINDICATIONS

• SYFOVRE is contraindicated in patients with ocular or periocular infections, and in patients with active intraocular inflammation
  

WARNINGS AND PRECAUTIONS

• Endophthalmitis and Retinal Detachments
  • Intravitreal injections, including those with SYFOVRE, may be associated with endophthalmitis and retinal detachments. Proper aseptic injection technique must always be used when administering SYFOVRE to minimize the risk of endophthalmitis. Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay and should be managed appropriately.
• Neovascular AMD
  • In clinical trials, use of SYFOVRE was associated with increased rates of neovascular (wet) AMD or choroidal neovascularization (12% when administered monthly, 7% when administered every other month and 3% in the control group) by Month 24. Patients receiving SYFOVRE should be monitored for signs of neovascular AMD. In case anti-Vascular Endothelial Growth Factor (anti-VEGF) is required, it should be given separately from SYFOVRE administration.
• Intraocular Inflammation
  • In clinical trials, use of SYFOVRE was associated with episodes of intraocular inflammation including: vitritis, vitreal cells, iridocyclitis, uveitis, anterior chamber cells, iritis, and anterior chamber flare. After inflammation resolves, patients may resume treatment with SYFOVRE.
• Increased Intraocular Pressure
  • Acute increase in IOP may occur within minutes of any intravitreal injection, including with SYFOVRE. Perfusion of the optic nerve head should be monitored following the injection and managed as needed.

ADVERSE REACTIONS

• Most common adverse reactions (incidence ≥5%) are ocular discomfort, neovascular age-related macular degeneration, vitreous floaters, conjunctival hemorrhage.

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
Most common adverse reactions in patients with PNH (incidence ≥10%) were injection-site reactions, infections, diarrhea, abdominal pain, respiratory tract infection, pain in extremity, hypokalemia, fatigue, viral infection, cough, arthralgia, dizziness, headache, and rash.

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.
