– Dosing of SGT-001 initiated in second cohort of patients in the IGNITE DMD clinical trial at 2E14 vg/kg –
– Clinical activities underway at additional study sites –
CAMBRIDGE, Mass., May 13, 2019 (GLOBE NEWSWIRE) -- Solid Biosciences Inc. (SLDB) today reported financial results for the first quarter ended March 31, 2019 and provided a business update.
“We have continued to advance our programs for Duchenne muscular dystrophy over the last few months, particularly our lead microdystrophin gene therapy candidate, SGT-001. Building on our findings from the preliminary Phase I/II clinical data that we announced in February, we initiated dosing at 2E14 vg/kg in the second cohort of patients,” said Ilan Ganot, Chief Executive Officer, President and Co-Founder of Solid Biosciences. “Now, we are working to progress as quickly as possible, and we look forward to providing additional data later this year.”
Today, Solid announced that two patients have been randomized in the second cohort of the Phase I/II IGNITE DMD study, including one patient dosed with 2E14 vg/kg of SGT-001 and another added to the control group. Shortly after dosing, the patient in the treatment group was diagnosed with a gastrointestinal infection that was classified as a serious adverse event unrelated to study drug, as well as a transient decline in platelet count that was considered a non-serious adverse event related to study drug; these events have fully resolved. In addition, the patient experienced a transient elevation of transaminases, as well as a transient increase in bilirubin higher than two times the upper limit of normal, which was rapidly resolved with an increase in oral glucocorticoids. This was reported to the FDA as a serious adverse event related to study drug. The patient is doing well and has resumed normal activities. Solid continues to enroll patients in IGNITE DMD per the study protocol and anticipates providing additional data later this year.
Solid recently initiated clinical trial activities for IGNITE DMD at additional sites, including the University of Massachusetts Memorial Medical Center. Screening continues at the University of Florida, the first clinical site for the study.
In late April, the Company presented additional preclinical data for SGT-001 at the 22nd Annual Meeting of The American Society of Gene and Cell Therapy (ASGCT), which reinforce its potential to promote unique microdystrophin expression and rescue muscle function. Solid also presented new preclinical data at the meeting supporting its next generation gene therapy programs.
Research and development expenses for the first quarter of 2019 were $23.3 million, compared to $11.9 million for the prior year period. The increase was primarily attributable to research and development personnel and related facility costs, manufacturing costs, and clinical development costs for SGT-001.
General and administrative expenses for the first quarter of 2019 were $7.0 million, compared to $4.0 million for the prior year period. The increase was primarily attributable to increased personnel costs and other corporate expenses associated with being a public company.
Net loss for the first quarter of 2019 was $29.6 million, compared to $15.9 million for the first quarter of 2018.
Solid had $94.7 million in cash, cash equivalents and available-for-sale securities as of March 31, 2019, compared to $122.5 million as of December 31, 2018.
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.
