Sigilon Therapeutics Reports Fourth Quarter and Full Year 2020 Financial Results and Business Highlights

CAMBRIDGE, Mass., March 18, 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 reported financial results for the fourth quarter and full year ended December 31, 2020 as well as certain other business highlights.

“2020 was a transformational period for Sigilon marked by the achievement of numerous key regulatory, clinical, and financial milestones, which we believe have positioned us to deliver on our commitments over the next several years,” commented Rogerio Vivaldi, M.D., Chief Executive Officer of Sigilon. “The modularity of our Shielded Living Therapeutics™ platform has enabled us to build a robust pipeline spanning a diverse range of chronic disorders, including rare blood, lysosomal and endocrine diseases. Notably, in 2020, our lead product candidate SIG-001 received IND and CTA clearance and we dosed the first patients in our Phase 1 /2 safety and dose-ranging study in severe to moderate-severe hemophilia A—a significant milestone for both our platform technology and the hemophilia community.”

Continued Dr. Vivaldi: “While our immediate priority is developing SIG-001, looking ahead, we are also leveraging our platform to advance several additional candidates—including SIG-005 for MPS-1, SIG-007 for Fabry disease and SIG-002 for Type 1 Diabetes—into the clinic over the next two years. Having successfully completed an upsized Initial Public Offering in December, which attracted a breadth of healthcare specialists and long-term focused shareholders, we are well-positioned to execute across each of these initiatives as we work to provide functional cures for patients.”

Recent Program Highlights

	•	In the fourth quarter, the Company dosed the first two patients in its Phase 1/2 safety and dose-ranging study with SIG-001 in severe to moderate-severe hemophilia A. No serious adverse events have been reported. At the initial dose levels for this study, tested in the first two patients, the Company has observed FVIII activity levels in the low- to mid-single digits.

	•	As dose levels increase, Sigilon initiated planned manufacturing changes in the first quarter of 2021 designed to, among other things, increase cell potency and enhance cell function. The Company has filed amendments to its CTA and IND for SIG-001 with the MHRA and FDA, respectively, to incorporate these changes.

	•	In December 2020, the FDA granted Orphan Drug designation to SIG-005 for the treatment of mucopolysaccharidosis type I (MPS-1), a chronic, progressive lysosomal disease.

	•	Four scientific abstracts outlining several ongoing preclinical studies in a range of lysosomal diseases were selected for presentation – including an oral presentation on mucopolysaccharidosis type II (MPS-2) – at the 17^th Annual WORLDSymposium™. In all these preclinical studies, platform cells produced high levels of biochemically active enzyme having characteristics nearly identical to the enzyme replacement therapies. Significant reduction in substrates across tissues were observed.

	•	In March 2021, the FDA granted Orphan Drug designation for SIG-007 for the treatment of Fabry disease, which is also a progressive, life-threatening lysosomal disease.

Corporate Updates

	•	In December 2020, the Company raised $144.9 million in gross proceeds from an initial public offering of 8,050,000 shares of common stock at a public offering price of $18.00 per share.

	•	Devyn Smith, Ph.D., will step down as Chief Operating Officer of Sigilon, effective on April 26, 2021, to assume a CEO role within the biotech industry.

Anticipated Milestones

	•	The Company is planning to file a CTA and/or IND for MPS-1 in the second quarter of 2021 and anticipates additional regulatory filings before the end of 2022.

	•	Phase 1/2 safety and dose-ranging study of SIG-001 in severe to moderate-severe hemophilia:

			•	Sigilon expects to disclose up to 9 months of follow up data for 3-4 patients in the third quarter of 2021; and

			•	Sigilon expects to complete enrollment of the study in the second half of 2021.

Financial Results

	•	Cash Position: Cash was $202.2 million as of December 31, 2020.

	•	R&D Expenses: Research and development expenses were $14.3 million for the fourth quarter of 2020 compared to $15.0 million for the fourth quarter of 2019. For the full year of 2020, research and development expenses were $53.5 million compared to $48.1 million for the same period in 2019. The increase in research and development expenses as compared to the prior year period was related to increased costs associated with Sigilon’s lead programs, increased costs associated with platform and pipeline development, an increase in personnel expenses costs due to headcount additions and an increase in stock-based compensation associated with stock option grants.

	•	G&A Expenses: General and administrative expenses were $3.5 million for the fourth quarter of 2020 compared to $2.9 million for the fourth quarter of 2019. For the full year of 2020, general and administrative expenses were $12.5 million compared to $10.2 million for the same period in 2019. The increase in general and administrative expenses as compared to the prior year period was primarily driven by an increase in professional fees and insurance costs that are primarily due to the costs of operating as a public company, an increase in personnel related costs due to increased headcount and an increase in stock-based compensation associated with stock option grants.

	•	Net Loss: Net loss was $15.2 million for the quarter ended December 31, 2020 compared to $14.7 million for the same period of 2019. For the full year 2020, Sigilon reported a net loss of $54.6 million, compared to a net loss of $43.9 million for the full year 2019.
