Sigilon Therapeutics Receives Orphan Drug Designation for SIG-005 for the Treatment of Mucopolysaccharidosis Type I

Dec 17, 2020 | PDF Version

Company plans to initiate a Phase 1/2 trial of SIG-005 in patients with mucopolysaccharidosis type I (MPS-1) in the second half of 2021

CAMBRIDGE, Mass., Dec. 17, 2020 (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-005 for the treatment of mucopolysaccharidosis type I (MPS-1), a chronic, progressive lysosomal storage disease.

SIG-005 contains a human cell line genetically modified with a non-viral vector designed to express human a-L-iduronidase (IDUA), an enzyme which is missing or defective in patients with MPS-1. The IDUA enzyme is essential for the breakdown of glycosaminoglycans in the lysosomes of patients with MPS-1, resulting in progressive, multiorgan involvement.

“We are pleased that the FDA has granted Orphan Drug designation to SIG-005 for the treatment of MPS-1, a devastating disease for which treatment options are limited,” said Deya Corzo, M.D., Chief Medical Officer at Sigilon. “Like many lysosomal disorders, MPS-1 is a chronic and progressive disease that affects multiple systems throughout the body creating complications that are challenging to manage optimally.”

Added Rogerio Vivaldi, M.D., President and Chief Executive Officer of Sigilon: “This is the second of what we hope will be multiple Orphan Drug designations for Sigilon as we continue progressing novel therapies for chronic diseases through our pipeline based on our Shielded Living Therapeutics™ platform. We look forward to exploring the potential of SIG-005 in patients with MPS-1 and anticipate initiating a Phase 1/2 clinical trial in this patient population in the second half of 2021.”

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-005, including tax credits for qualified clinical trials and seven years of market exclusivity in the United States following commercial approval by the FDA.
