Gemini Therapeutics Reports Full Year 2020 Financial Results and Provides Business Update

March 29, 2021 GMT

CAMBRIDGE, Mass.--(BUSINESS WIRE)--Mar 29, 2021--

Gemini Therapeutics, Inc. (Nasdaq: GMTX), a clinical stage precision medicine company developing innovative treatments for genetically defined age-related macular degeneration (AMD), today reported its financial results for the year ended December 31, 2020 and provided a business update.

“The past 12 months have been truly transformative for Gemini as we successfully transitioned to a publicly traded precision medicine company with a strong balance sheet and resources to advance to important clinical milestones,” said Jason Meyenburg, Chief Executive Officer of Gemini Therapeutics, Inc. “The successful completion of the Phase 1 study provided encouraging safety results and biomarker evidence GEM103 has biological activity consistent with functioning CFH. These results provided us the confidence to advance into two Phase 2a trials from which we expect to see initial data later this year. Our open-label Phase 2a ReGAtta study in patients with genetically-defined dry AMD completed enrollment in February. Also in February, we initiated a Phase 2a study of GEM103 as a potential add-on therapy for patients treated with anti-VEGF for wet AMD who are at risk for macular atrophy. We are committed to the further development of these innovative potential new treatments for patients and look forward to sharing our progress throughout the year.”

Recent Business Highlights

  • Debuted as a publicly traded precision medicine company focused on genetically defined age-related macular degeneration (AMD) following the closing of a business combination with FS Development Corp (FSDC). In February 2021, Gemini Therapeutics closed the business combination with FSDC, a special purpose acquisition company (SPAC) sponsored by Foresite Capital. Also in February 2021, the Company expanded its leadership team with the appointment of Brian Piekos as Chief Financial Officer and the promotion of Walter R. Strapps, Ph.D., to Chief Scientific Officer. Mr. Piekos joined from AMAG Pharmaceuticals where he most recently served as Executive Vice President, Chief Financial Officer and Treasurer. Dr. Strapps joined Gemini in 2018 from Intellia Therapeutics where he led CRISPR/Cas9 therapeutic programs through discovery into IND-enabling studies across a range of tissues and indications.

  • Made significant progress in the clinical development of GEM103, the Company’s lead precision medicine program, targeting trial enrichment with genetically defined patients.
    • In February 2021, the Company announced the completion of enrollment of approximately 60 patients in its Phase 2a “ReGAtta” study, a dose escalation trial of GEM103, a recombinant human complement factor H (CFH) in dry AMD patients with loss of function CFH variants. The Company expects to share data from the trial, designed to evaluate safety and tolerability, as well as measures of intraocular pharmacokinetics and exploratory, disease-relevant biomarkers, in the first half of 2021. The Company believes the learnings from the Phase 2a trial will inform the design of the Phase 2b sham-controlled study which will be powered for efficacy.
    • In February 2021, Gemini Therapeutics commenced a Phase 2a study of GEM103 as a potential add-on therapy for patients suffering from wet AMD who have or may be at risk for macular atrophy (MA) but require ongoing anti-VEGF treatment. Six-month dosing data related to safety, tolerability, effect on intraocular CFH levels and disease-related biomarkers is expected around year-end 2021.
    • Positive Phase 1 data for GEM103 were presented at the 2020 Virtual Annual Meeting of the American Academy of Ophthalmology (AAO). In November 2020, Gemini Therapeutics announced that GEM103 met all endpoints in a Phase 1 clinical study. Data presented by Arshad M. Khanani, M.D., M.A., Director of Clinical Research at Sierra Eye Associates and Clinical Associate Professor of Ophthalmology, University of Nevada, demonstrated that there were no dose-limiting toxicities or treatment-related adverse events in 12 patients receiving a single intravitreal (IVT) injection of GEM103. Pharmacokinetic and exploratory biomarkers of complement activity as measured in the aqueous humor (AH) from patients enrolled in the Phase 1 single ascending dose (SAD) study support the mechanism of action of GEM103 and continued clinical development. Additionally, in GEM103 demonstrated a promising safety profile, with no observed dose-limiting toxicities or treatment-related adverse events.

Full Year 2020 Financial Results

Gemini reported a net loss of $40.8 million for the full year 2020 compared to $41.4 million for the same period in 2019. Research and development expenses were $28.2 million and $34.5 million for the twelve months ended December 31, 2020 and 2019, respectively. The full year decrease was primarily due to reduced spend in our product development activities as we focused our effort on the GEM103 product candidate.

General and administrative expenses were $5.9 million and $6.8 million for the twelve months ended December 31, 2020 and 2019, respectively. The full year decrease was primarily due to reduced employee headcount and related expenses.

Following the close of the business combination with FSDC and PIPE financing in February 2021, the Company expects its cash will fund operations into 2023.

About the Phase 2a ReGAtta Study

The ongoing Phase 2a, multi-center, open-label, multiple ascending dose study of GEM103 in genetically defined patients with GA secondary to dry AMD is designed to investigate safety and tolerability, PK, exploratory ocular biomarkers, and measures of retinal anatomy and function. In the study, GEM103 is delivered monthly by an intravitreal injection and PK and biomarkers of complement regulation are determined from aqueous humor sampling. The study was designed to enroll approximately 60 patients. The study population was enriched for patients with genetic variants in CFH that have been linked to the progression of dry AMD from early to late-stage.

About the Phase 2a Study of Repeat Intravitreal Injections of GEM103 in Neovascular Age-related Macular Degeneration

The ongoing Phase 2a, multicenter, multiple-dose study in subjects with Neovascular Age-related Macular Degeneration (nAMD) with or at risk for macular atrophy, is designed to investigate the safety and tolerability of GEM103 as an adjunct to standard of care aflibercept therapy. The study is designed to enroll approximately 45 patients randomized 2:1 between GEM103 plus aflibercept and sham plus aflibercept arms, with treatment administered via intravitreal injection every other month for twelve months. CFH levels and biomarkers of complement regulation are determined from aqueous humor sampling throughout the study with visual acuity and macular atrophy size measured at defined dosing dates.

About GEM103

Gemini’s lead program, GEM103, is a pioneering precision medicine approach, targeting trial enrichment with genetically defined patients. GEM103 targets a genetically defined subset of age-related macular degeneration (AMD) patients with complement dysregulation. Of the 15 million dry AMD patients, approximately 40% (or six million) have variants in the complement factor H (CFH) gene. Such loss of function variants are associated with increased dry AMD disease risk. GEM103 is believed to be the first ever recombinant complement modulator and is a full-length and human, recombinant complement factor H (rCFH) protein. When delivered by intravitreal injection, GEM103 has the potential to address unmet medical need in genetically defined AMD patients by circumventing the complement dysfunction resulting from CFH loss of function variants, and slowing the progression of their retina disease. The U.S. Food and Drug Administration (FDA) granted Fast Track Designation for GEM103 for the treatment of dry AMD in patients with CFH loss of function gene variants.

About Dry Age-Related Macular Degeneration (AMD)

Age-related macular degeneration (AMD) is a progressive retinal disease affecting millions of older adults, and the leading cause of irreversible blindness in the western world. Symptoms, which include blurry vision, loss of night vision and loss of central vision, make activities of daily living such as reading, driving and even recognizing faces progressively more difficult. Third-party reports indicate there are approximately 16 million patients with AMD in the United States alone. Dry AMD, which results from an interaction of environmental and genetic risk factors, represents about 90% of that population (or about 15 million) in the US compared to about 1.4 million with wet AMD. Genetic risk of developing dry AMD is significant, with approximately 70% attributable risk of advanced disease to heritability, while aging and smoking confer the strongest non-genetic risk. CFH risk variants occur in approximately 40% of patients with dry AMD and these patients have a significantly increased risk of developing the disease as well as progression from intermediate AMD to GA. The complement system, of which CFH is a modulator, is dysregulated in patients with these risk variants, and results in amplification of aberrant inflammatory responses in the eye. Over time, this dysregulation leads to damage to the macular region of the retina.
