Peers on Argus
APLS gained 2.92% ahead of new GALE and SYFOVRE data, while only one biotech peer in the momentum scan (MLTX) was up about 1.03% and other listed peers showed modest positive moves. This points to a stock-specific reaction driven by company news rather than a broad sector rotation.
Historical Context
| Date | Event | Sentiment | Move | Catalyst |
|---|---|---|---|---|
| Feb 10 | Earnings call notice | Neutral | -1.1% | Announcement of date for Q4 and full-year 2025 results call. |
| Jan 12 | JP Morgan update | Positive | -15.0% | Preliminary 2025 revenues and market share gains for SYFOVRE and EMPAVELI. |

APLS often shows stronger moves on major clinical or commercial updates, with at least one prior instance of a sharp selloff following positive strategic/financial disclosures.
Over the past few months, Apellis has focused on investor outreach and clinical validation. On Nov 25, 2025, it highlighted participation in investor conferences. On Dec 3, 2025, NEJM published positive Phase 3 VALIANT data for EMPAVELI, which saw a modest price gain. January 2026 featured J.P. Morgan conference appearances and strong preliminary 2025 revenue figures, yet the stock sold off after that update. The current GALE and SYFOVRE data presentations extend this clinical narrative in geographic atrophy.
Market Pulse Summary
This announcement highlights five-year GALE extension data and multiple SYFOVRE-focused presentations, emphasizing long-term safety and efficacy in geographic atrophy. The program builds on earlier Phase 3 OAKS and DERBY findings, reinforcing Apellis’s position in GA. Investors may watch for detailed lesion-growth outcomes, real-world treatment patterns, and safety signals such as neovascular AMD rates as they assess how this growing evidence base supports the franchise over time.

- Company will debut five-year results from GALE study showing meaningful impact of early and continuous treatment with SYFOVRE® (pegcetacoplan injection)
WALTHAM, Mass., Feb. 19, 2026 (GLOBE NEWSWIRE) -- Apellis Pharmaceuticals, Inc. (Nasdaq: APLS) today announced that eight abstracts were accepted for oral presentations at the 49th Macula Society Annual Meeting, taking place February 25-28 in San Diego, California.
New data to be presented include the comprehensive analysis from the GALE extension study following five years of continuous treatment with SYFOVRE® (pegcetacoplan injection), the most prescribed treatment for geographic atrophy (GA) secondary to age-related macular degeneration (AMD).
“We look forward to sharing the five-year results from our GALE extension study, which show the importance of early treatment with SYFOVRE for preserving retinal tissue and delaying disease progression in patients with geographic atrophy,” said Caroline Baumal, M.D., chief medical officer, Apellis. “Backed by the largest GA data set with the longest follow-up, these new findings demonstrate the clinically meaningful impact that SYFOVRE can have for patients living with this devastating disease.”

About GALE Long-Term Extension Study
GALE (n=792) is a Phase 3, multicenter, open label, extension study to evaluate the long-term safety and efficacy of SYFOVRE® (pegcetacoplan injection) in patients with geographic atrophy (GA) secondary to age-related macular degeneration (AMD). The objectives of the study are to evaluate the long-term incidence and severity of ocular and systemic treatment emergent adverse events as well as change in the total area of GA lesions as measured by fundus autofluorescence. More than 80 percent of participants who completed the OAKS and DERBY studies entered the GALE study.
Patients included in the 5-year GALE lesion growth reduction analyses were in the SYFOVRE treatment arms through Month 24 in the OAKS and DERBY studies and remained on the same regimen in GALE. Sham-treated patients in the Phase 3 OAKS and DERBY studies were eligible to transition to SYFOVRE treatment in GALE after Month 24, so a projected sham arm was used to estimate the growth of GA lesions without treatment between Months 24 and 60. The projected sham arm is based on the observed linear growth of GA lesions over two years and was validated by a fellow eye analysis. It was estimated as the average 12-month mean rate of change in the OAKS and DERBY sham arms through Month 24.
About the Phase 3 OAKS and DERBY Studies
OAKS (n=637) and DERBY (n=621) are Phase 3, multicenter, randomized, double-masked, sham-controlled studies comparing the efficacy and safety of SYFOVRE® (pegcetacoplan injection) with sham injections across a broad and heterogenous population of patients with geographic atrophy (GA) secondary to age-related macular degeneration (AMD). The studies evaluated the efficacy of monthly and every-other-month SYFOVRE in patients with GA assessed by change in the total area of GA lesions from baseline as measured by fundus autofluorescence.
In these studies at 24 months, both every-other-month and monthly SYFOVRE reduced GA lesion growth with increasing effects over time and a well-demonstrated safety profile.
About SYFOVRE® (pegcetacoplan injection)
SYFOVRE® (pegcetacoplan injection) is the first-ever approved therapy for GA. By targeting C3, SYFOVRE is designed to provide comprehensive control of the complement cascade, part of the body’s immune system. SYFOVRE is approved in the United States for the treatment of GA secondary to age-related macular degeneration.
About Geographic Atrophy (GA)
Geographic atrophy (GA) is an advanced form of age-related macular degeneration and a leading cause of blindness worldwide, impacting more than one million Americans and five million people worldwide.1,2 It is a progressive and irreversible disease caused by the growth of lesions, which destroy the retinal cells responsible for vision. The vision loss caused by GA severely impairs independence and quality of life by making it difficult to participate in daily activities. On average, it takes only 2.5 years for GA lesions to start impacting the fovea, which is responsible for central vision.3
U.S. Important Safety Information for SYFOVRE® (pegcetacoplan injection)
CONTRAINDICATIONS
- SYFOVRE is contraindicated in patients with ocular or periocular infections, in patients with active intraocular inflammation, and in patients with hypersensitivity to pegcetacoplan or any of the excipients in SYFOVRE. Systemic hypersensitivity reactions (e.g., anaphylaxis, rash, urticaria) have occurred.
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.
- Retinal Vasculitis and/or Retinal Vascular Occlusion
- Retinal vasculitis and/or retinal vascular occlusion, typically in the presence of intraocular inflammation, have been reported with the use of SYFOVRE. Cases may occur with the first dose of SYFOVRE and may result in severe vision loss. Discontinue treatment with SYFOVRE in patients who develop these events. Patients should be instructed to report any change in vision without delay.
- 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 and3% 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.
- In clinical trials, use of SYFOVRE was associated with increased rates of neovascular (wet) AMD or choroidal neovascularization (
- 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.
- 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.
