LEBANON, N.J., May 7, 2018 /PRNewswire/ -- Provention Bio, Inc. (Provention), a clinical stage biopharmaceutical company dedicated to sourcing, developing and commercializing novel therapeutics aimed at intercepting and preventing immune-mediated diseases, announced today that it has selected Netherlands-based Intravacc to lead product development and manufacturing of clinical trial material for Provention's Coxsackievirus B (CVB) vaccine (PRV-101). France-based L2D Services SARL/Leads-To-Development (L2D) is providing expert development, regulatory and project management support to ensure rapid progress of PRV-101 into clinical development.

CVB, an enterovirus, has been identified as a possible common trigger for type 1 diabetes (T1D) onset. Vaccination of at-risk populations against CVB infection may lead to the prevention or delay in onset of T1D. The CVB vaccine was developed initially by Vactech Ltd. of Finland and licensed to Provention in April, 2017. Provention is planning to initiate first in-human clinical trials in 2020.

Enteroviruses are responsible for an estimated 30 million infections annually in the US. CVB contributes significantly to enteroviral healthcare costs, since it can result in hospitalization and severe morbidity. Usually asymptomatic or presenting as cold-like symptoms, fever, rash, hand-foot-mouth disease, and/or mild gastrointestinal distress, CVB infections can occasionally cause more serious and sometimes life-threatening illnesses including pericarditis, myocarditis, meningitis and pancreatitis.

Provention, in partnership with Intravacc, Vactech and L2D is now developing its CVB vaccine for large scale manufacture of clinical trial material in accordance with current Good Manufacturing Practices (cGMP). Intravacc was chosen as Provention's manufacturing partner based on its expertise and excellent track in enterovirus vaccine development, including IPV, sIPV, EV-71, and CV-A16, as well as Intravacc's state-of-the-art vaccine cGMP production facilities. PRV-101 will be developed using Intravacc's proven and well-established platform technology, including certain proprietary cell lines and production processes.

Ashleigh Palmer, co-founder and CEO of Provention Bio, stated, "Selecting Intravacc for PRV-101's cGMP production is an important next step in our plan to initiate a potentially transformative clinical program to develop a vaccine to prevent acute coxsackievirus B infection and, ultimately, prevent or delay the onset of as much as half of the world's cases of T1D. We welcome this opportunity to work alongside Intravacc, Vactech and L2D to advance our PRV-101 program to the clinic." 

Intravacc's CEO Thijs Veerman, MSc, commented, "We are very excited to be involved in this project. Intravacc is uniquely positioned to develop cGMP clinical material for this vaccine and ensure its specifications, quality and patient-readiness. We have the necessary knowledge, expertise and experience to advance Provention's PRV-101 program to the next stage and beyond."

About Type 1 Diabetes and Coxsackievirus B Infection

T1D is a life-impacting chronic disease caused by immune destruction of the insulin-producing cells in the pancreas. Today, there is no cure. The only means for managing this devastating disease is life-long blood glucose monitoring and insulin replacement by way of injection, infusion or, potentially, pancreatic cell transplantation. 

Global longitudinal studies of more than 200,000 children screened, and more than 17,000 followed, over two decades in Finland by Vactech's scientific founders and collaborators have identified CVB infection as a likely trigger for T1D onset. From this research, it was discovered that the diabetes process often starts after CVB infection. Insulin-producing cells in the pancreas express specialized receptors used for cellular infection by CVB. As a result, an exacerbated immune reaction against the virus may be involved in triggering the autoimmunity targeting the pancreas and gut, which appears to precede the onset of T1D and associated celiac disease.

Importantly, the CVB-related risk of T1D autoimmunity was significantly reduced in children whose mothers previously had a CVB infection, thereby suggesting a transfer of protective CVB antibodies to their offspring via placenta and breast milk. This observation suggests the potential benefit of CVB vaccination for children.
