Sigilon Therapeutics Reports Third Quarter 2022 Financial Results and Business Highlights
Nov 10, 2022 | PDF Version
Identified important optimization features for its platform to mitigate PFO risks in current and future programs
Advanced iPS cell differentiation protocol for the diabetes program in preparation for anticipated IND-enabling studies in 2023
Continued optimization of the MPS-1 program, with plans to initiate IND-enabling studies in the second half of 2023
CAMBRIDGE, Mass., Nov. 10, 2022 (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 reported financial results for the third quarter ended September 30, 2022 as well as certain other business highlights.
“This year, we have made significant progress advancing our SLTx platform, including key improvements to our cross-linking chemistry designed to strengthen the stability of our spheres. In addition, we have developed preclinical models designed to predict pericapsular fibrotic overgrowth, including macrophage attachment assays and humanized mouse models, which we believe will be key to mitigating risk of an allogeneic immune response and accelerate product development,” said Rogerio Vivaldi, M.D., President and CEO of Sigilon. “I am grateful for the extraordinary effort put forth by our team to identify these important optimization features for the platform and to incorporate them into our diabetes and MPS-1 programs. We look forward to providing additional preclinical data for both programs showcasing the potential of the SLTx platform in the coming months.”
Recent Program Highlights and Anticipated Milestones
- After the development of inhibitors and the discovery of pericapsular fibrotic overgrowth (PFO) in a hemophilia A patient last year, Sigilon evaluated ways to optimize its SLTx platform. This resulted in improvements to the Company’s proprietary cross-linking chemistry, which has the potential to strengthen the spheres. Sigilon also developed allogeneic PFO prediction methods designed to rapidly evaluate the potential PFO response to encapsulated cell products. The Company has used these models to evaluate the allogeneic immune response to its current product candidates for diabetes and MPS-1. In addition, the Company expects to use these models to develop product candidates designed to avoid an allogeneic immune response and mitigate the risk of PFO, which the Company refers to as ImmunoQuiet™ cell therapies.
- At the Cell and Gene Therapy Meeting on the Mesa in October 2022, the Company presented data showing its proprietary iPS cell differentiation protocol for SIG-002, its product candidate for type 1 diabetes, which generates stem cell-derived islets that are similar to human cadaveric islets with a high percentage of beta cells, high levels of insulin content and glucose-regulated insulin secretion. In addition, the Company demonstrated that SIG-002 was efficacious in an STZ-induced diabetes mouse model after 10 weeks. The treated mice cleared an oral glucose challenge similar to clearance levels shown in non-diabetic control mice and maintained blood glucose levels at time zero after an overnight fast. The Company expects to initiate Investigational New Drug (IND)-enabling studies for SIG-002 in the second half of 2023 and expects to file an IND application for SIG-002 in 2024.
- Sigilon is optimizing its MPS-1 program to penetrate the blood brain barrier to address neurological manifestations, as well as to extend plasma half-life for the non-neurological manifestations. The Company expects to withdraw its Clinical Trial Applications (CTA) for its first MPS-1 product candidate, SIG-005, before year-end and plans to initiate IND-enabling studies for its optimized MPS-1 program in the second half of 2023. Sigilon also plans to file an IND application for a product candidate in its MPS-1 program in 2024.
- The Company submitted a Clinical Hold Response to the FDA for its hemophilia A program and withdrew its IND application for SIG-001. Sigilon also received approval to withdraw its CTA for SIG-001 for hemophilia A in the United Kingdom and plans to finalize activities pertaining to these regulatory filings before year-end.
- Cash Position: Cash, cash equivalents and marketable securities were $78.3 million as of September 30, 2022 compared to $123.4 million as of December 31, 2021. The decrease was primarily driven by cash used for operating activities. The Company expects that its cash, cash equivalents and marketable securities as of September 30, 2022 will support its currently anticipated operating expenses and capital expenditure requirements into 2024.
- R&D Expenses: Research and development expenses were $8.3 million for the third quarter of 2022 compared to $16.6 million for the third quarter of 2021. The decrease in research and development expenses was primarily related to decreased activity in ongoing platform and other early-stage program development, personnel expenses, facility-related expenses, which were offset by increased expenses related to the Company’s diabetes program. The decrease in platform and other early-stage program activity and personnel expenses was primarily due to the Company’s reprioritization of the development of the MPS-1 program, diabetes program and platform optimization following the Company’s restructuring activities in December 2021. The decrease in facility-related expenses was primarily due to the sublease of a portion of its facility.
- G&A Expenses: General and administrative expenses were $4.4 million for the third quarter of 2022 compared to $5.0 million for the third quarter of 2021. The decrease in general and administrative expenses was primarily related to decreased personnel expenses primarily as a result of the Company’s reprioritization and restructuring activities that occurred in December 2021 and the sublease of a portion of its facility.
- Net Loss: Net loss was $8.7 million for the third quarter of 2022 compared to $20.2 million for the third quarter of 2021. The decline in net loss as compared to the prior year was primarily due to savings realized from the Company’s reprioritization and corporate restructuring in December 2021.
