Supporting Clinical Research in Rare & Orphan Disorders

Advancing Scientific Innovation in Rare & Orphan Disorders

With expertise in pediatric rare and orphan diseases, VeraSci supports clinical trials from Rett syndrome (RTT), Arginase deficiency disorder, Myasthenia Gravis, Bardet-Biedl Syndrome (BBS) and Alström Syndrome (AS) to Mucopolysaccharidoses disorders (MPS). Genetic diseases, such as Mucopolysaccharidoses disorders, result in neurodegeneration and affect multiple body systems over the lifespan. These diseases require a targeted treatment strategy that focuses on symptomatic relief as well as the remittance of disease progression. Fortunately, there are several emerging treatments in various stages of clinical development.

Achieving therapeutic success in the management of these diseases requires identifying the right target, using the ideal treatment, administering the treatment at the right dose at the right time, and employing clinical endpoints that are reliable, robust, and fit for the purpose.

We bring extensive experience in clinical trial design, execution of reliable global studies including linguistics, and scientific expertise in clinical, behavioral, and cognitive measurement across a broad range of rare and orphan diseases of varying severities to ensure your clinical trial is positioned for success. VeraSci can even supply a qualified centralized assessor to sites that don’t have a qualified rater available. The assessor travels to sites, provides expert clinical and cognitive ratings, fills out required paperwork, and can enter data into the study EDC when needed.

Dependable Solutions for Global Clinical Trials

VeraSci is not just there in the beginning; we take care of your study objectives and data throughout the entire trial. As your partner, we leverage experience gained through hundreds of trials and ensure the highest quality data, all while anticipating any issues that can derail or delay your study before they arise.
