Gemini Therapeutics Announces Initiation of GEM103 Phase 2a Study as an Add-On to Anti-VEGF Therapy for the Treatment of Wet AMD Patients at Risk for Progressive Vision Loss Due to Macular Atrophy

02/01/2021
  • Topline Data Expected in 2H 2021

CAMBRIDGE, Mass. – February 1, 2021 – Gemini Therapeutics, a clinical stage precision medicine company developing innovative treatments for genetically defined AMD, today announced the commencement of a Phase 2a trial advancing 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-vascular endothelial growth factor (anti-VEGF) treatment. Topline data related to safety, tolerability, effect on intraocular CFH levels and biomarkers is expected in the second half of 2021.

“Current anti-VEGF therapies have improved the quality of life for patients with wet AMD,” said Marc E. Uknis, M.D., F.A.C.S., Chief Medical Officer of Gemini Therapeutics. “However, there is no therapy for the MA that can develop in some patients. In these patients, ongoing anti-VEGF therapy has been associated with a compartmental insufficiency of CFH activity. In this setting, GEM103, a recombinant human CFH, has the potential to be a meaningful add-on therapy.”

“The addition of a clinical research program targeting a selected wet AMD population is a natural next step for Gemini, and builds on our existing focus in genetically-defined dry AMD,” said Jason Meyenburg, Chief Executive Officer of Gemini Therapeutics. “Wet AMD affects approximately 1.4 million people in the United States, and GEM103 is uniquely suited to correct CFH insufficiency associated with VEGF inhibition. This study is an important next phase in our understanding of the potential role of GEM103 as an add-on therapy in a subset of patients with wet AMD who go on to have co-morbid macular atrophy.” 

The clinical trial will be a randomized, single-masked, and sham-controlled study of patients requiring ongoing VEGF inhibition for wet AMD. The objective of the study is to assess safety, tolerability, effect on CFH levels and disease-relevant biomarkers in the ocular compartment to inform future development strategies.

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 native complement modulator, full-length recombinant complement factor H (rCFH) protein. When delivered by intravitreal injection, GEM103 has the potential to address unmet medical need in genetically-defined subsets of AMD patients by circumventing dysfunctional CFH loss-of-function variants and slowing the progression of their retinal disease.

About Wet Age-Related Macular Degeneration (AMD)

Gemini Therapeutics is a clinical stage precision medicine company developing novel therapeutic compounds to treat genetically defined age-related macular degeneration (AMD).  Gemini’s lead candidate, GEM103, is a recombinant form of the human complement factor H protein (CFH), and is designed to address both complement hyperactivity and restore retinal health in patients with AMD. GEM103 is currently in a Phase 2a trial in dry AMD patients with a CFH risk variant. The company has generated a rich pipeline including recombinant proteins, gene therapies, and monoclonal antibodies for multiple indications.

We cannot assure you that the forward-looking statements in this press release will prove to be accurate. These forward-looking statements are subject to a number of significant risks and uncertainties that could cause actual results to differ materially from expected results, including, among others, the ability to complete the business combination due to the failure to obtain approval from FS Development Corp.’s shareholders or satisfy other closing conditions in the Merger Agreement, the occurrence of any event that could give rise to the termination of the Merger Agreement, the ability to recognize the anticipated benefits of the business combination, the outcome of any legal proceedings that may be instituted against FS Development Corp. or Gemini following announcement of the proposed business combination and related transactions, the impact of COVID-19 on Gemini’s business and/or the ability of the parties to complete the business combination, the ability to obtain or maintain the listing of FS Development Corp.’s common stock on Nasdaq following the proposed business combination, costs related to the proposed business combination, changes in applicable laws or regulations, the possibility that FS Development Corp. or Gemini may be adversely affected by other economic, business, and/or competitive factors, and other risks and uncertainties, including those to be included under the header “Risk Factors” in the registration statement on Form S-4 to be filed by FS Development Corp. with the SEC and those included under the header “Risk Factors” in the final prospectus of FS Development Corp. related to its initial public offering. Most of these factors are outside of FS Development Corp.’s and Gemini’s control and are difficult to predict. Furthermore, if the forward-looking statements prove to be inaccurate, the inaccuracy may be material.
