Ultragenyx and Solid Biosciences Announce Strategic Collaboration to Develop and Commercialize New Gene Therapies for Duchenne Muscular Dystrophy - Seite 2

“Ultragenyx has a demonstrated track record of success in developing and commercializing innovative therapies for rare diseases,” said Ilan Ganot, Co-Founder, President and Chief Executive Officer at Solid Biosciences. “We believe it is the partner of choice for exploring new gene therapy opportunities for patients with Duchenne.”

Solid’s proprietary microdystrophin construct has exhibited functional benefit in preclinical models. In preclinical studies, animals expressing a microdystrophin capable of restoring neuronal nitric oxide synthase (nNOS) resisted fatigue better than those expressing a microdystrophin that does not. Patients dosed with Solid’s proprietary microdystrophin construct at the 2E14 vg/kg dose in Solid’s ongoing IGNITE DMD clinical trial have also preliminarily demonstrated nNOS activity and function, further validating these preclinical results. Solid expects to dose the next patient in the IGNITE DMD clinical trial, using SGT-001 produced using its improved HSV manufacturing process, in the first quarter of 2021.

Ultragenyx intends to use its AAV-based HeLa PCL platform including HeLa 3.0 improvements for the development of product candidates. The platform enables large 2,000 liter commercial-scale AAV-based gene therapy product manufacturing. The PCL platform yields high-quality product from a highly reproducible, highly scalable, and less expensive process – a distinct vantage in higher dose indications like Duchenne. The capsid planned is an AAV8 variant with a favorable immunological profile that has been used successfully in the large scale 2,000 liter production process.

About Ultragenyx

Ultragenyx is a biopharmaceutical company committed to bringing novel products to patients for the treatment of serious rare and ultra-rare genetic diseases. The company has built a diverse portfolio of approved therapies and product candidates aimed at addressing diseases with high unmet medical need and clear biology for treatment, for which there are typically no approved therapies treating the underlying disease.

The company is led by a management team experienced in the development and commercialization of rare disease therapeutics. Ultragenyx’s strategy is predicated upon time- and cost-efficient drug development, with the goal of delivering safe and effective therapies to patients with the utmost urgency and ensuring majority access to its therapies for patients who can benefit.
