CHARLESTOWN, Mass., March 13, 2024 (GLOBE NEWSWIRE) -- Solid Biosciences Inc. (Nasdaq: SLDB), a life sciences company developing precision genetic medicines for neuromuscular and cardiac diseases, today reported financial results for the fourth quarter and full year ended December 31, 2023, and provided a business update.

"2023 was an exciting and transformational year for Solid where we completed the integration with AavantiBio, while diversifying and expanding our pipeline. We strengthened our management team with the hiring of a CMO, Dr. Gabriel Brooks, and CFO, Kevin Tan, and advanced our next generation gene therapy for Duchenne, SGT-003, towards the clinic with IND clearance in Q4 and received Fast Track Designation and Orphan Drug Designation in Q4 2023 and Q1 2024, respectively. We continued to bring in additional assets, including SGT-501 for the treatment of a fatal childhood disease called CPVT from ICS Maugeri, while moving additional high potential programs and capsids through preclinical models,” said Bo Cumbo, President and CEO of Solid Biosciences. “We enter 2024 with significant momentum from our recently completed financing in January which raised $108.9 million from a syndicate of leading investors. 2024 will be a year of execution and we look forward to rapidly bringing SGT-003 into the clinic, advancing SGT-501 towards IND filing and most importantly, continuing to bring hope to all those suffering from devastating genetic diseases.”

Company Updates

  • Solid expects to initiate dosing in the Phase 1/2 trial of SGT-003 in pediatric patients with Duchenne in the second quarter of 2024. A safety update is expected mid-year and initial data from the first two cohorts of the trial is expected in Q4 2024.
  • Solid announced it expects to file an IND for its first cardiac gene therapy candidate, SGT-501 for the treatment of catecholaminergic polymorphic ventricular tachycardia (CPVT), in the first quarter of 2025.
  • Solid has entered into a non-exclusive licensing agreement for use of its proprietary, muscle-targeted AAV-SLB101 capsid. Solid aims to license AAV-SLB101 broadly to both companies and academic institutions pursuing treatments for rare diseases.

Recent Company Highlights

  • On January 16, 2024, Solid announced that the FDA granted Orphan Drug Designation for its Duchenne gene therapy candidate SGT-003. This designation provides certain benefits, including specified financial incentives, to support clinical development and the potential for up to seven years of market exclusivity in the U.S. upon regulatory approval.
  • On January 8, 2024, Solid announced a $108.9 million private placement with new and existing investors. The Company expects to use net proceeds of $104.0 million from the private placement to fund ongoing pipeline development programs, business development activities, and for working capital and other general corporate purposes.
  • On December 7, 2023, Solid announced the FDA granted Fast Track Designation for SGT-003. The Fast Track program facilitates the expedited development and review of new drugs that are intended to treat serious or life-threatening conditions and demonstrate the potential to address unmet medical needs.
  • On November 14, 2023, Solid announced that it had received FDA clearance for the Phase 1/2 trial of SGT-003.

Fourth Quarter and Full-Year 2023 Financial Highlights

There were no collaboration revenues for the fourth quarter of 2023 and 2022. There were no collaboration revenues for the full year ended December 31, 2023, compared to $8.1 million for the full year ended December 31, 2022. Collaboration revenue in 2022 was related to research services and cost reimbursement from the Collaboration Agreement with Ultragenyx, which the Company entered in the fourth quarter of 2020.

Research and development expenses for the fourth quarter of 2023 were $15.4 million, compared to $21.3 million for the fourth quarter of 2022. Research and development expenses for the full year ended December 31, 2023, were $76.6 million, compared to $78.4 million for the full year ended December 31, 2022. The decrease of $1.8 million in research and development expenses was primarily due to a decrease in expenses related to SGT-001 due to our decision to prioritize SGT-003, offset by an increase in costs for SGT-003 and SGT-501.

General and administrative expenses for the fourth quarter of 2023 were $6.8 million, compared to $7.6 million for the fourth quarter of 2022. General and administrative expenses for the full year ended December 31, 2023, were $27.8 million, compared to $28.9 million for the full year ended December 31, 2022.

Net loss for the fourth quarter of 2023 was $20.3 million, compared to $15.2 million for the fourth quarter of 2022. Net loss for the full year ended December 31, 2023, was $96.0 million, compared to $86.0 million for the full year ended December 31, 2022. The increase in net loss was primarily related to a gain on acquisition and collaboration revenue in 2022, offset by decreased research and development costs, decreased general and administrative expenses, and an increase in yields on cash equivalents and available-for-sale securities in 2023.

Solid had $123.6 million in cash, cash equivalents, and available-for-sale securities as of December 31, 2023, compared to $213.7 million as of December 31, 2022. The Company expects that its cash, cash equivalents, and available-for-sale securities as of December 31, 2023, together with the net proceeds from the January 2024 private placement, will enable it to fund key strategic priorities into 2026.
