Sigilon Therapeutics Announces Strategic Reprioritization

CAMBRIDGE, Mass., Dec. 13, 2021 (GLOBE NEWSWIRE) — Sigilon Therapeutics, Inc. (NASDAQ: SGTX), a biotechnology company that seeks to develop functional cures for chronic diseases through its Shielded Living TherapeuticsTM platform, today announced a strategic reprioritization to enable the Company to focus on MPS-1 and diabetes.
“There have been key learnings in our Phase 1/2 trial of SIG-001 for Hemophilia A. While we continue to investigate the findings from our SIG-001 study to help inform our development of the platform, following a review of our programs, we have made the strategic decision to refocus our pipeline. We will be prioritizing MPS-1-a rare lysosomal disease-with our product candidate that is designed to produce the same enzyme as the native human structure, and Type 1 diabetes, alongside our partner, Eli Lilly, with a program that utilizes iPSC-derived islets,” said Rogerio Vivaldi, President and CEO of Sigilon. “As part of our plan to refocus our pipeline, we will also make workforce reductions, which are expected to extend our cash runway.”
In November, Sigilon reported that fibrosed spheres were observed during a retrieval procedure for the third patient enrolled in its Phase 1/2 study of SIG-001 in severe or moderately severe hemophilia A. The Company plans to update regulatory agencies following the SIG-001 Safety Review Committee meeting scheduled in December and continue to follow all three patients per study protocol. In addition, the Company does not expect to initiate patient dosing in the Phase 1/2 clinical trial of SIG-005 for MPS-1 until further investigation is complete.
The Company will reduce its full-time workforce by approximately 38%. The positions eliminated are primarily related to research, manufacturing, and general and administrative services. The significant reduction in expenses associated with the strategic reprioritization is expected to extend the Company’s cash runway into 2024.
“We believe that prioritizing our MPS-1 and diabetes programs puts Sigilon in the best position for success,” said Dr. Vivaldi. “I want to thank our valued employees who will be departing Sigilon for their important contributions to the Company.”
