Press Release

– Additional patient dosed at 2E14 vg/kg in second cohort of IGNITE DMD trial –

– Study protocol amended to expedite clinical execution of SGT-001 –

– Recent $60M capital raise extends runway into the fourth quarter of 2020 –

CAMBRIDGE, Mass., Aug. 14, 2019 (GLOBE NEWSWIRE) -- Solid Biosciences Inc. (Nasdaq: SLDB) today reported financial results for the second quarter ended June 30, 2019 and provided a business update.

“We continue to execute on our mission to bring transformative therapies to patients with Duchenne muscular dystrophy, and we have taken several steps towards reaching our goal,” said Ilan Ganot, Chief Executive Officer, President and Co-Founder of Solid Biosciences. “We have amended the IGNITE-DMD protocol to expedite our clinical path evaluating our SGT-001 gene transfer candidate and have treated a second patient in our higher dose cohort. We also bolstered our financial resources and extended our runway. Looking forward, we continue to anticipate providing a data update from the IGNITE DMD clinical trial in the months ahead.”

Recent Developments

• Solid has amended the IGNITE DMD Phase I/II trial protocol for SGT-001, an adeno-associated viral gene transfer candidate under investigation for Duchenne muscular dystrophy (DMD). The changes to the protocol include adding an upper weight limit of 25 kg for at least the next patient dosed in the second cohort and removing the matched patient control arm for the rest of the second cohort in the IGNITE DMD trial. Solid expects that these protocol updates will expedite the path to obtaining IGNITE DMD clinical trial results as well as the broader development of the SGT-001 program. Solid remains committed to dosing larger patients in the future. The company intends to provide a data update from the ongoing IGNITE DMD clinical trial later this year.

• Today, Solid announced that the second patient has been dosed in the higher dose cohort of the IGNITE DMD clinical trial.

• As announced previously, the company raised $60 million through a private placement, which closed on July 30, 2019. Participants included a mix of new and existing investors, including Perceptive Advisors, LLC; Boxer Capital, LLC; EcoR1 Capital, LLC; Bain Capital Life Sciences; RA Capital Management; Waverly Capital; Invus and certain board members and executive officers.

Financial Highlights

Research and development expenses for the second quarter of 2019 were $21.6 million, compared to $13.6 million for the second quarter of 2018. The increase was primarily attributable to compensation and other costs associated with additional headcount, as well as facility costs and increased costs related to the clinical development and manufacturing activities for SGT-001. 

General and administrative expenses for the second quarter of 2019 were $5.4 million, compared to $4.6 million for the second quarter of 2018. The increase was primarily attributable to increased personnel costs, partially offset by a decrease in other corporate expenses.

Net loss for the second quarter of 2019 was $26.5 million, compared to $18.0 million for the second quarter of 2018.

Solid had $67.4 million in cash, cash equivalents and available-for-sale securities as of June 30, 2019, compared to $122.5 million as of December 31, 2018. Including the proceeds from the July 2019 private placement, Solid expects that that company has sufficient capital to fund its operations into the fourth quarter of 2020.

About SGT-001

Solid’s lead candidate, SGT-001, is a novel adeno-associated viral (AAV) vector-mediated gene transfer under investigation for its ability to address the underlying genetic cause of Duchenne muscular dystrophy (DMD), mutations in the dystrophin gene that result in the absence or near-absence of dystrophin protein. SGT-001 is a systemically administered candidate that delivers a synthetic dystrophin transgene, called microdystrophin, to the body. This microdystrophin encodes for a functional protein surrogate that is expressed in muscles and stabilizes essential associated proteins, including neuronal nitric oxide synthase (nNOS). SGT-001 utilizes AAV9, which has an affinity for muscle and is currently being evaluated in multiple clinical programs in other indications. Data from Solid’s preclinical program suggest that SGT-001 has the potential to slow or stop the progression of DMD, regardless of genetic mutation or disease stage.

SGT-001 is based on pioneering research in dystrophin biology by Dr. Jeffrey Chamberlain of the University of Washington and Dr. Dongsheng Duan of the University of Missouri. SGT-001 has been granted Rare Pediatric Disease Designation, or RPDD, and Fast Track Designation in the United States and Orphan Drug Designations in both the United States and European Union.
