Solid Biosciences Reports Full Year 2017 Financial Results and Provides Corporate Update

- Company Continues To Work To Address Clinical Hold On IGNITE DMD -

Cambridge, MA, March 29, 2018 - Solid Biosciences Inc. (NASDAQ:SLDB) today reported financial results for the full year ended December 31, 2017 and provided a corporate update.

“Since our inception, we’ve worked hard to build a pipeline of innovative and complementary approaches for treating Duchenne muscular dystrophy (DMD). Those efforts resulted in the initiation of the first clinical trial for our microdystrophin gene transfer, SGT-001, at the end of 2017, which was recently put on clinical hold by the FDA,” said Ilan Ganot, Founder and Chief Executive Officer of Solid Biosciences. “We believe that SGT-001 has the potential to significantly benefit patients with DMD. We look forward to working with the FDA to understand the requirements for resuming the clinical trial and will provide an update as soon as appropriate.”

“We are also working diligently to progress our second candidate, SB-001, into preclinical development, as well as to advance our efforts to build our preclinical and clinical pipeline,” continued Ganot. “The executive team and I are grateful to patients and our employees, partners, advisors and investors for their continued support as we work to realize our mission to end DMD.”

Business Highlights and Recent Developments


    Initiated IGNITE DMD, the Company’s first clinical trial, in November 2017. The Phase I/II adaptive clinical trial is designed to evaluate the safety and efficacy of a single intravenous (IV) dose of SGT-001, Solid’s novel microdystrophin gene transfer, in ambulatory children and non-ambulatory adolescents with DMD. The Company believes that SGT-001 has the potential to slow or halt the progression of DMD regardless of a patient’s underlying genetic mutation.


    Reported that the U.S. Food and Drug Administration (FDA) placed a clinical hold on IGNITE DMD following the Company’s report of a Suspected Unexpected Serious Adverse Reaction (SUSAR) observed in the first patient dosed in the clinical trial. Solid has halted enrollment and dosing in IGNITE DMD and is awaiting the formal clinical hold letter from the FDA to understand the requirements for resuming the clinical trial.


    Submitted a response to the FDA regarding the previously announced partial clinical hold on the high dose of SGT-001 in IGNITE DMD, which is related to the number of vials and manufacturing lots utilized per patient, as well as manufacturing processes to support the higher-dose group. The Company is awaiting feedback from the FDA.



    Established a research collaboration with Synpromics Ltd in September 2017, providing Solid access to a set of Synpromics’ muscle-selective promoters for use in the development of new treatment options for DMD, including next generation gene therapy candidates.


    Completed a preferred unit financing in 2017, raising net proceeds of $79.5 million, and an Initial Public Offering (IPO) of common stock in January 2018, raising an additional $129.3 million in net proceeds. Solid intends to use the proceeds from these financings to advance its mission to develop meaningful treatments for DMD.


    Strengthened leadership team in 2017 with the appointment of Jennifer Ziolkowski, CPA, as Chief Financial Officer, the promotion of Carl Morris, Ph.D., to Chief Scientific Officer and the promotion of Joel Schneider, Ph.D., to Chief Technology Officer and Head of Exploratory Research and Development.

Solid’s Anticipated Milestones and Expectations


    Upon receipt of a formal clinical hold letter, work with the FDA on the necessary steps to resume IGNITE DMD.


    Initiate preclinical activities in 2018 for SB-001, an anti-LTBP4 antibody aimed at reducing fibrosis and inflammation by blocking TGF-ß activation.


    Present and publish preclinical data for SGT-001 and other pipeline assets.


    Advance research and development activities for Solid’s expanding pipeline of next generation gene therapy and complementary disease-modifying therapy programs.


    Further enhance disease understanding and inform Solid’s programs by continuing to partner with scientists, academic experts, patients and families in the DMD community.


    Continue to build Solid’s team and infrastructure to support its advancing pipeline.

Financial Highlights

Solid Biosciences reported a net loss of $53.2 million for the full year 2017 as compared to $23.8 million for the prior year. 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 in preparation of becoming a publicly traded company.

Research and development expenses for the full year 2017 were $39.9 million as compared to $20.1 million for the prior year. The increase in research and development expenses was primarily driven by increased spending on third party-related costs used to advance Solid’s preclinical and clinical development activities for SGT-001, as well as increased salary and related benefits costs due to the increase in employee headcount.



General and administrative expenses were $15.0 million for the full year 2017 as compared to $5.5 million for the prior year. The increase in general and administrative expenses was primarily due to an increase in legal and accounting fees related to the Company’s IPO, the increase in employee headcount and the impact of stock-based compensation in 2017.

Solid ended 2017 with $69.1 million in cash, cash equivalents and available-for-sale securities compared to $37.7 million as of December 31, 2016. The increase was primarily the result of the completion of the Company’s preferred unit financing in 2017, which resulted in aggregate net proceeds of $79.5 million. Cash as of December 31, 2017 excludes $129.3 million in net proceeds raised in the Company’s January 2018 IPO.

Financial Guidance

Based on its current operating plan, Solid expects its cash, cash equivalents and available-for-sale securities as of December 31, 2017, together with the net proceeds from its IPO, will enable it to fund its operating expenses and capital expenditure requirements until the end of 2019.

About SGT-001

Solid Biosciences’ 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 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 gene, 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). Data from Solid’s preclinical program suggests 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.
