Press Release:Solid Biosciences Reports Second Quarter 2018 Financial Results and Provides Business Update

- IGNITE DMD Phase I/II Clinical Trial Patient Screening Has Resumed -

CAMBRIDGE, Mass., Aug. 10, 2018 (GLOBE NEWSWIRE) -- Solid Biosciences Inc. (NASDAQ:SLDB) today reported financial results for the second quarter ended June 30, 2018 and provided a business update.

“It is an exciting time for Solid as we work to advance our innovative pipeline designed to address Duchenne muscular dystrophy for all patients with this devastating disease,” said Ilan Ganot, Chief Executive Officer, President and Founder of Solid Biosciences. “We look forward to dosing additional patients with our microdystrophin gene therapy candidate, SGT-001, in IGNITE DMD at the University of Florida, where patient screening is now underway. We also continue to build upon our scalable GMP manufacturing process and capabilities so that we are well positioned to bring this potentially transformative therapy to patients, if approved.”

Recent Developments

  • Announced in June that the U.S. Food and Drug Administration (FDA) lifted the clinical hold on IGNITE DMD, Solid’s Phase I/II clinical trial for SGT-001 for the treatment of Duchenne muscular dystrophy (DMD). In connection with the lifting of the clinical hold, Solid made changes to the IGNITE DMD protocol, including adding an enhanced glucocorticoid regimen and additional monitoring measures, as well as a specification that eculizumab should be available as a treatment option if complement activation is observed in future patients. The Company plans to enroll and dose several children prior to dosing additional adolescents and now has the choice to obtain an intermediate muscle biopsy at 45 days post administration of SGT-001.
  • Received approval from the University of Florida Investigational Review Board (IRB) and resumed patient screening in IGNITE DMD at the University.
  • Announced new preclinical data for SGT-001 at the 21st Annual Meeting of the American Society of Gene and Cell Therapy in May, which further demonstrated its potential to be an important treatment approach for DMD. Specifically, long-term preclinical data demonstrated that a single intravenous administration of a low, medium or high dose of SGT-001 resulted in body-wide microdystrophin transgene expression that was sustained for at least 30 months, as well as restoration of key microdystrophin-associated proteins, including neuronal nitric oxide synthase (nNOS). In a different study, the restoration of nNOS and associated activity were shown to result in improvements in muscle histopathology and function in preclinical models, suggesting that nNOS activity could serve as an important marker of molecular function.
  • Announced in June that the Company expanded its clinical development expertise with the appointment of biopharmaceutical veteran Martin Freed, M.D., F.A.C.P., to its Board of Directors. Dr. Freed brings to Solid more than 25 years of strategic development and operational expertise from across the biopharmaceutical and life sciences industries. In addition, Ilan Ganot assumed the role of President after the retirement of Gilad Hayeem from his role as President and Director.
  • Continued to progress its exploratory pipeline of next generation gene therapy assets, as well as its biomarker work intended to improve drug discovery and clinical development. This work includes an agreement with Flagship Biosciences to validate the use of its computational Tissue Analysis (cTA™) platform to quantify SGT-001-produced microdystrophin and additional signature proteins localized to the muscle membrane, such as nNOS, as supportive measures of microdystrophin function in IGNITE DMD.

Anticipated Milestones

  • Continue to advance IGNITE DMD with the dosing of additional patients in the coming months and expanding the clinical trial footprint with additional sites both in the U.S. and abroad. The Company remains on track to communicate initial data from a pre-specified interim analysis in the second half of 2019.
  • Progress the Company’s anti-LTBP4 monoclonal antibody program intended to reduce fibrosis and inflammation in the muscle. Solid continues development of its lead antibodies and remains on track to initiate preclinical activities by year end 2018.

Financial Highlights
Solid Biosciences reported a net loss of $18.0 million for the second quarter of 2018 as compared to $11.3 million for the second quarter of 2017. The increase in net loss for the year was due to increased research and development expenses, as well as investments in the Company’s infrastructure.

Research and development expenses for the second quarter of 2018 were $13.6 million as compared to $8.6 million for the prior year period. The increase in research and development expenses was primarily driven by 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. These increases were offset by a reduction in the preclinical costs associated with SGT-001.

General and administrative expenses were $4.6 million for the second quarter of 2018 as compared to $3.3 million for the prior year period. The increase in general and administrative expenses was primarily due to personnel and facility related costs, as well as other corporate expenses.

Solid ended the second quarter of 2018 with $162.8 million in cash, cash equivalents and available-for-sale securities as compared to $69.1 million as of December 31, 2017. The increase was primarily the result of the completion of the Company’s initial public offering on January 30, 2018.

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, in the United States and Orphan Drug Designations in both the United States and European Union.
