Sigilon Therapeutics Receives Orphan Drug Designation for SIG-007 for the Treatment of Fabry Disease

Mar 5, 2021 | PDF Version

CAMBRIDGE, Mass., March 05, 2021 (GLOBE NEWSWIRE) — Sigilon Therapeutics, Inc. (NASDAQ:SGTX), a biotechnology company that seeks to develop functional cures for chronic diseases through its Shielded Living Therapeutics™ platform, today announced that the United States Food and Drug Administration (FDA) has granted orphan drug designation to SIG-007 for the treatment of Fabry disease, a progressive, life-threatening lysosomal disease.

SIG-007 is comprised of cells that are genetically modified with a non-viral vector to express human alpha-galactosidase A, or AGAL. Fabry disease is caused by AGAL deficiency and the accumulation of certain substrates within a patient’s cells, which contribute to multi-organ complications including kidney failure, gastrointestinal symptoms, strokes, and heart disease at a young age.

“The current standard of care for Fabry disease requires intravenous administration, which may involve long infusion times and the potential for infusion-associated reactions. While these therapies have helped patients manage their disease, long-term exposure has led to severe complications, including impaired renal function,” said Deya Corzo, M.D., Chief Medical Officer at Sigilon. “Based on preclinical results, we believe SIG-007 may provide continuous and prolonged release of functional enzyme at levels sufficient to produce clinical benefits, while alleviating the treatment burden for these patients.”

Commented Rogerio Vivaldi, M.D., President and Chief Executive Officer of Sigilon: “This marks our third orphan drug designation, and further highlights our commitment to bringing potential functional cures to patients who suffer from chronic, rare diseases. We are pleased to have secured this important designation at such an early stage of SIG-007’s development.”

Sigilon has initiated several IND enabling studies with plans to file four INDs within the next 12-24 months, which includes SIG-007 in patients with Fabry disease.

Orphan drug designation is granted by the FDA Office of Orphan Products Development to advance the evaluation and development of safe and effective therapies for the treatment of rare diseases or conditions affecting fewer than 200,000 people in the United States. Having received the designation, Sigilon is eligible for various development incentives for SIG-007, including tax credits for qualified clinical trials and seven years of market exclusivity in the United States following commercial approval by the FDA.
