CHARLESTOWN, Mass., Aug. 13, 2024 (GLOBE NEWSWIRE) -- Solid Biosciences Inc. (Nasdaq: SLDB) (the “Company” or “Solid”), a life sciences company developing precision genetic medicines for neuromuscular and cardiac diseases, today reported financial results for the second quarter ended June 30, 2024, and provided a business update.
Bo Cumbo, President and CEO of Solid Biosciences, commented: “In the second quarter of 2024, we commenced patient dosing in the Phase 1/2 INSPIRE DUCHENNE trial of SGT-003 – a key milestone for our lead gene therapy candidate – which has been well tolerated to date. Given these results and ongoing patient interest in new Duchenne therapies, we plan to expand the trial with additional sites and continuous patient dosing, while carefully managing patient screening to ensure consistency of both baseline criteria and future clinical data. We remain on track to share initial safety, expression, and (90-day) functional data at the end of this year.”
Gabriel Brooks, M.D., Chief Medical Officer of Solid Biosciences, commented: “We are very encouraged that dosing has been well tolerated with no observed serious adverse events and that the safety results were consistent with the IND-enabling NHP toxicology study. To date, in this study of SGT-003, immunosuppression was achieved with steroids alone. SGT-003 leverages a rationally designed, novel capsid, AAV-SLB101, with the intent to target and more potently transduce muscle. We believe that the safety data seen to date are encouraging for not only SGT-003, but also our proprietary capsid, AAV-SLB101. We firmly believe Duchenne patients remain in need of better treatment options, and SGT-003 with its proprietary capsid, enhanced manufacturing process and differentiated transgene (uniquely containing the nNOS binding domain and flexible construct design), represents a potential next-generation therapy.”
Mr. Cumbo continued, “As an organization, we are steadfast in our commitment to develop a truly transformative next-generation treatment option for patients in need around the world. To that end, I am pleased to share that we have made significant progress in clinical trial site initiations, with a total of six sites anticipated to be recruiting patients in Q4 2024 – including a site in Canada, now that Health Canada has authorized our Clinical Trial Application (CTA). With additional sites in Europe expected to be activated in 1H 2025, Solid is positioned to deliver on our commitment to patients globally.
“Beyond Duchenne, we continue to make strides across our pipeline beginning with SGT-501, our lead cardiac gene therapy program to treat CPVT, with an IND submission expected in the first half of 2025.
“We have also made progress in furthering the ongoing development of our earlier stage drug candidates. Based upon the preliminary human safety data from our Duchenne program, along with the preclinical expression and distribution data generated in multiple internal programs to date, we have transitioned our BAG3 and TNNT2 cardiac programs to our proprietary capsid, AAV-SLB101. This change will position us to synergistically leverage our clinical experience and manufacturing expertise with AAV-SLB101 across the majority of our programs going forward.
“With $190.3M as of June 30, 2024, we remain well positioned to execute across our strategically built, robust pipeline of neuromuscular and cardiac gene therapy candidates. Based on our current programs, and our goal of having three-to-four INDs approved by the end of 2026, I believe Solid is poised to become an industry-leading precision genetic medicines company,” Mr. Cumbo concluded.
Additional Company Highlights
AAV-SLB101, Solid’s proprietary capsid used in SGT-003, has been well tolerated in initial human, NHP, and mouse studies. 10 different academic labs and one corporation have begun utilizing AAV-SLB101.
On July 1, 2024, Solid was added to the broad-market Russell 3000? Index as part of the annual reconstitution. Russell indexes are widely used by investment managers and institutional investors for index funds and as investment strategy benchmarks, and Solid’s inclusion brings enhanced exposure and visibility within the financial community.
Solid presented an oral presentation and six posters at the American Society of Gene and Cell Therapy (ASGCT) 2024 Annual Meeting, which took place May 7-11. The presentations highlighted Solid’s AAV manufacturing and purification improvements, vector biology updates, and a comprehensive non-clinical data overview of SGT-003.
Second Quarter 2024 Financial Highlights
Cash Position: Solid had approximately $190.3 million in cash, cash equivalents, and available-for-sale securities as of June 30, 2024, compared to approximately $123.6 million as of December 31, 2023. The Company expects that its cash, cash equivalents, and available-for-sale securities as of June 30, 2024, will enable it to fund key strategic priorities into 2026.
Research and Development (R&D) Expenses: R&D expenses for the three months ended June 30, 2024, were $19.5 million, compared to $19.8 million for the three months ended June 30, 2023. The decrease of $0.3 million was due to a $3.3 million decrease in manufacturing and research costs for SGT-003, a $0.3 million decrease in costs for SGT-001 due to our decision to deprioritize development of SGT-001, and a $0.4 million decrease in external expenses, offset by a $1.7 million increase in costs for SGT-501 primarily related to manufacturing and research, a $1.7 million increase in other product candidate costs primarily related to BAG3, and a $0.2 million increase in personnel related costs.
General and Administrative (G&A) Expenses: G&A expenses for the three months ended June 30, 2024, were $8.3 million, compared to $7.1 million for the three months ended June 30, 2023. The increase of $1.2 million was primarily related to a $0.9 million increase in legal fees and a $0.3 million increase in recruiting and license fees.
Net Loss: Net loss for the three months ended June 30, 2024, was $25.1 million compared to a net loss of $24.6 million for the same period in 2023. Basic and diluted net loss per share was $0.61 and $1.25 for the three-month periods ended June 30, 2024, and June 30, 2023, respectively.
