CHARLESTOWN, Mass., May 11, 2023 (GLOBE NEWSWIRE) -- Solid Biosciences Inc. (Nasdaq: SLDB), a life sciences company developing genetic medicines for neuromuscular and cardiac diseases, today reported financial results for the first quarter ended March 31, 2023, and provided a business update.

“In the first quarter of 2023, we made strong progress across multiple programs in our diversified pipeline of genetic medicines and remain on track to achieve important milestones this year,” said Bo Cumbo, President, and CEO of Solid Biosciences. “We look forward to presenting data from our Friedreich’s ataxia program, next-generation Duchenne muscular dystrophy program, novel capsid program, and our process development activities as we participate in seven presentations next week at the American Society of Gene and Cell Therapy Annual Meeting. With cash runway into 2025, we are well positioned to create additional momentum from our leading-edge technology portfolio and multiple product development programs in the months ahead.”

The Company is on track for an anticipated Investigational New Drug (IND) submission for our Duchenne gene therapy program, SGT-003 in the fourth quarter of 2023 and, subject to IND clearance, the first patient dosing in late-2023. Solid also continues to advance preclinical programs in its other neuromuscular and cardiac indications, including AVB-202-TT for Friedreich’s Ataxia, and AVB-401 for treatment of BAG3 mediated dilated cardiomyopathy.

First Quarter 2023 Financial Highlights

There were no collaboration revenues for the first quarter of 2023, compared to $1.9 million, for the first quarter of 2022. Collaboration revenue in the 2022 period was related to research services and cost reimbursement from our Collaboration Agreement with Ultragenyx, which the Company entered into in the fourth quarter of 2020.

Research and development expenses for the three months ended March 31, 2023, were $24.6 million, compared to $20.0 million for the three months ended March 31, 2022. The increase of $4.6 million in research and development expenses was primarily due to a $7.0 million increase in costs for SGT-003 for manufacturing and related costs and a $0.8 million increase in costs for other development programs, offset by a $2.9 million decrease in costs for SGT-001 due to a transition to SGT-003.

General and administrative expenses were $7.4 million for each of the three months ended March 31, 2023 and 2022.

Net loss for the first quarter of 2023 was $30.1 million, compared to $25.3 million for the first quarter of 2022. The increase in net loss was the result of a greater investment in research and development to progress DMD candidates.

Solid had $185.5 million in cash, cash equivalents, and available-for-sale securities as of March 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 will enable it to fund key strategic priorities into 2025.
