Announced strategic reprioritization, with plans to advance mucopolysaccharidosis type I (MPS-1) and diabetes as lead indications as well as continued platform optimization
Strengthened leadership team with appointment of new Chief Technical Operations Officer and other key leadership changes
Current cash position expected to fund operating plans into 2024
“In 2021, we made important adjustments to our overall corporate and clinical strategy as well as our leadership team to best position us for sustained future growth and success,” said
Recent Program Highlights
- In
December 2021 , Sigilon announced a strategic reprioritization to enable the Company to focus on MPS-1 and diabetes as well as platform optimization. Sigilon expects the significant reduction in expenses associated with the strategic reprioritization to extend the Company’s cash runway into 2024. The Brazilian Health Surveillance Agency , ANVISA, has cleared the Company’s Clinical Trial Application (CTA) for SIG-005 in MPS-1. In addition, Sigilon plans to submit an Investigational New Drug (IND) Application to theU.S. Food and Drug Administration for SIG-005.- In
October 2021 , theEuropean Commission granted orphan drug designation to SIG-005 for the treatment of MPS-1. - Last month, Sigilon presented preclinical data on the rare lysosomal diseases MPS-1 and MPS-6 at the 18th Annual WORLDSymposium™, held
February 7-11 th inSan Diego .

Strategic Priorities and Anticipated Milestones
The Company is focusing its development efforts in three strategic areas:
MPS-1: SIG-005 is the Company’s product candidate that contains a cell line genetically modified with a non-viral vector to express human α L iduronidase, or IDUA, encapsulated within Sigilon’s spheres. SIG-005 is being developed to treat the non-neurological manifestations of mucopolysaccharidosis type 1, or MPS-1, in patients with the disease. The Company believes its product candidates for lysosomal diseases can leverage the well understood mechanism of enzyme replacement therapies, or ERTs, by using engineered cells to express functional human enzyme or other protein that more closely resemble normal physiology in a continuous manner. Sigilon is also working to develop next-generation product candidates to address the neurological manifestations of lysosomal diseases, starting with MPS-1, using transporter molecules designed to penetrate the blood brain barrier and molecules designed to extend plasma half-life.
Diabetes: SIG-002 is the Company’s product candidate designed to replace islet cells for the treatment of type 1 diabetes, or T1D. In T1D, the immune system attacks and destroys the insulin-producing beta cells within the endocrine islets of the pancreas. Insulin deficiency results in dysregulation of glucose metabolism. In
Platform optimization: Sigilon is continuing to optimize its Shielded Living Therapeutics, or SLTx, platform, which combines advanced cell engineering with cutting-edge innovations in biocompatible materials to pioneer a new class of therapeutics. In
In these prioritized areas, Sigilon expects to achieve the following milestones:
- In the second half of 2022, the Company expects to:
- Present results of preclinical studies designed to evaluate PFO and mitigation strategies in humanized mice and non-human primates; and
- Submit amendments to the Company’s CTAs for SIG-005 for MPS-1 in the
United Kingdom andBrazil .
- In 2023, the Company expects to:
- Initiate a Phase 1/2 trial of SIG-005 for MPS-1 in the
United Kingdom and/orBrazil ;
- Submit an IND application for MPS-1 in
the United States ; and - Conduct IND-enabling studies for SIG-002 in diabetes.
- Initiate a Phase 1/2 trial of SIG-005 for MPS-1 in the
Financial Results
- Cash Position: Cash, cash equivalents and marketable securities were
$123.4 million as ofDecember 31, 2021 compared to$202.2 million as ofDecember 31, 2020 . - R&D Expenses: Research and development expenses were
$14.7 million for the fourth quarter of 2021 compared to$14.3 million for the fourth quarter of 2020. Research and development expenses were$65.1 million for the year endedDecember 31, 2021 compared to$53.5 million for the year endedDecember 31, 2020 . The increase in research development for the fourth quarter of 2021 of$0.4 million was primarily the result of an increase in personnel expenses associated with the Company’s restructuring activities inDecember 2021 , which were partially offset by a decrease in expenses for Sigilon’s SIG-002 program and a reduction in activities associated with its core research and platform development activities. The increase in research and development expenses for the year endDecember 31, 2021 was primarily related to ongoing platform, pipeline, and development activities related to Sigilon’s SIG-005 and SIG-007 programs, which received orphan drug designation inDecember 2020 andMarch 2021 , respectively. The expenses increased for SIG-005 as the Company submitted a CTA to the MHRA in theUnited Kingdom and the ANVISA inBrazil . Personnel expenses for the year endedDecember 31, 2021 increased by$3.6 million primarily as a result of the increase in headcount in Sigilon’s research and development function, severance associated with the Company’s previously announcedDecember 2021 restructuring and increases in stock-based compensation. These increases were partially offset by a reduction of$3.7 million associated with Sigilon’s SIG-002 program. The decrease in SIG-002 related expenses was due to timing of preclinical activities. - G&A Expenses: General and administrative expenses were
$4.6 million for the fourth quarter of 2021 compared to$3.5 million for the fourth quarter of 2020. General and administrative expenses were$20.2 million for the year endedDecember 31, 2021 compared to$12.5 million for the year ended 2020. The increase in general and administrative expenses for the fourth quarter of 2021 was primarily attributed to a$0.7 million increase in the expansion of internal infrastructure to support the Company’s operations as a public company and a$0.3 million increase in employee related expenses associated with the Company’s restructuring activities inDecember 2021 . The increase in general and administrative expenses for the year endedDecember 31, 2021 was driven by a$3.7 million increase in personnel expenses, which was primarily the result of an increase in headcount and an increase in stock-based compensation. Stock-based compensation expense increased to$3 .9 million from$1.8 million for the year endedDecember 31, 2020 . In addition, the increase in general and administrative expenses for the year endedDecember 31, 2021 was driven by a$3.3 million increase in the expansion of internal infrastructure to support the Company’s operations as a public company. - Net Loss: Net loss was
$17.7 million for the fourth quarter of 2021 compared to$14.1 million for the fourth quarter of 2020. Net loss was$77.3 million for the year endedDecember 31, 2021 compared to$54.6 million for the year endedDecember 31, 2020 .
