Rhea-AI Summary

Sigilon Therapeutics, Inc. (NASDAQ:SGTX) reported its Q2 2021 financial results, highlighting a net loss of $20.4 million compared to $13.5 million in 2020. While the company remains focused on resolving a clinical hold on its Phase 1/2 trial for hemophilia A, it has made advancements in its pipeline, including preclinical data on SIG-005 for MPS-1. The cash position decreased to $162.4 million from $202.2 million at year-end 2020. Sigilon aims to initiate a Phase 1/2 trial for SIG-005 in late 2021, with key leadership changes also announced.

Positive

• Anticipation of starting Phase 1/2 trial of SIG-005 in 2H 2021.
• Successful preclinical results for SIG-005 in MPS-1.
• Expected 80% reduction in manufacturing lead times for SIG-005.

Negative

• Net loss increased to $20.4 million from $13.5 million year-over-year.
• Clinical hold on Phase 1/2 trial for SIG-001 due to adverse events.
• Cash position decreased to $162.4 million from $202.2 million at year-end 2020.

CAMBRIDGE, Ma., Aug. 10, 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 second quarter ended June 30, 2021 as well as certain other business highlights.

“While we remain focused on patient safety and resolving the clinical hold on our Phase 1/2 trial in hemophilia A, we are also taking important steps to advance our broad pipeline of product candidates,” said Rogerio Vivaldi, M.D., M.B.A., Chief Executive Officer of Sigilon. “Last month, we had the opportunity to present preclinical data on our candidate, SIG-005, for MPS-1 – a rare genetic disorder – and are encouraged by these results. With our CTA recently filed in the UK and Brazil and an additional filing in the U.S. anticipated, we look forward to starting our clinical journey in lysosomal diseases. If these filings are approved, we plan to initiate our second trial before year-end. In addition, we are working to streamline the manufacturing process of SIG-005 by incorporating cryopreservation of the cell component, potentially reducing the manufacturing lead times by approximately 80 percent. We remain committed to realizing the promise of our platform technology and advancing our current pipeline of product candidates, which includes programs in diabetes and immune-mediated disease. We are also continuing to look for additional opportunities, including strategic partnerships, to grow our existing portfolio.”

Recent Program Highlights

• In July 2021, the Phase 1/2 study of SIG-001 was placed on clinical hold by the U.S. Food and Drug Administration (FDA). The clinical hold was initiated following Sigilon’s submission of a serious adverse event (SAE) and temporary enrollment halt to the FDA and other regulatory agencies. To date, three patients have been dosed with SIG-001 and are continuing to be monitored by study protocol. The third patient, who received the highest dose of study drug, developed inhibitors to FVIII, which is a well-known complication of FVIII therapy. The patient responded well to medical treatment. Among other things, the FDA has requested additional information and data on factors potentially contributing to the development of inhibitors in this patient as well as follow-up data relating to FVIII inhibitor and activity levels.
  
  
• Three scientific abstracts were selected for presentation—including an oral presentation on mucopolysaccharidosis type I (MPS-1)—at the 16th International Symposium on MPS and Related Diseases (MPS 2021), which took place July 23 – 25, 2021. The Company also presented initial results from preclinical studies of expanded pipeline programs in immune-mediated and metabolic disorders at the American Society of Gene and Cell Therapy (ASGCT) 24th Annual Meeting in May.
  
  
• In June 2021, the Company filed a Clinical Trial Application (CTA) in the UK for SIG-005 for the treatment of MPS-1. In addition, the Company filed a CTA in Brazil for SIG-005 in July 2021.
  
  
• The Company plans to cryopreserve the cell component for the manufacture of SIG-005 in the Phase 1/2 clinical trial of MPS-1, allowing these cells to be produced in advance of the manufacture of drug product. This planned manufacturing change is expected to reduce the manufacturing lead times for patient doses of SIG-005 by approximately 80 percent.
  

Corporate Updates

• Deya Corzo, M.D., is stepping down as Chief Medical Officer. The Company entered into an agreement with Dr. Corzo providing for transition services until her separation on August 13, 2021. As Sigilon initiates a search for a CMO, the Board of Directors and management will work closely together on key clinical priorities.
  
  
• Philip Ashton-Rickardt, Ph.D., joined Sigilon as Chief Scientific Officer. Dr. Ashton-Rickardt is a highly regarded scientific leader in the field of immunology with a successful track record of developing cell therapies and platform technologies.
  
  
• Ajay Rai, M.B.A., joined the Company as Senior Vice President, Head of Business Development. Mr. Rai brings over two decades of business development, finance and partnering experience in the life sciences to Sigilon.
  
  
• Sigilon has initiated a search for a full-time Chief Financial Officer and, in the meantime, has engaged Michael Wyzga, M.B.A., former Chief Financial Officer of Genzyme, to provide finance-related services on an interim basis.
  
  
• Brooke Story, M.B.A., was appointed to the Company’s Board of Directors. Ms. Story has more than 20 years of extensive commercial and operating experience in the healthcare industry.
  
  

Anticipated Milestones

• Sigilon expects to initiate a Phase 1/2 trial of SIG-005 in patients with MPS-1 in the second half of 2021.
  
  
• The Company expects to disclose up to 9 months of follow-up data for three patients from the Phase 1/2 safety and dose-ranging study of SIG-001 in severe to moderate-severe hemophilia in the third quarter of 2021.
  

Financial Results

• Cash Position: Cash was $162.4 million as of June 30, 2021 compared to $202.2 million as of December 31, 2020.
  
  
• R&D Expenses: Research and development expenses were $17.8 million for the second quarter of 2021 compared to $12.5 million for the second quarter of 2020. The increase in research and development expenses 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 in December 2020 and March 2021, respectively. Personnel expenses increased primarily as a result of the increase in headcount in Sigilon’s research and development function and increases in stock-based compensation. Stock-based compensation expense increased to $0.9 million from $0.3 million for the three months ended June 30, 2021 and 2020, respectively. These increases were partially offset by a reduction of $0.5 million and $0.6 million associated with Sigilon’s SIG-001 and SIG-002 programs, respectively. The decrease in SIG-001-related expenses was due to the timing of manufacturing activities in the second quarter of 2020 and the decrease in SIG-002-related expenses was due to changes in the timeline for preclinical activities.
  
  
• G&A Expenses: General and administrative expenses were $5.0 million for the second quarter of 2021 compared to $2.8 million for the second quarter of 2020. The increase in general and administrative expenses was primarily driven by a $0.8 million in increased costs from operating as a public company in the second quarter of 2021. In addition, personnel expenses increased by $1.0 million primarily as a result of the increase in headcount in Sigilon’s general and administrative function and increases in stock-based compensation. Stock-based compensation expense increased to $1.1 million from $0.4 million for the three months ended June 30, 2021 and 2020, respectively.
  
  
• Net Loss: Net loss was $20.4 million for the second quarter ended June 30, 2021 compared to $13.5 million for the same period of 2020.
