Open Orphan/hVIVO Signs Contract with UK Government for the Development of a COVID-19 Human Challenge Study Model

COVID-19 human challenge study model to safely speed up development of an efficacious vaccine.

hVIVO has the world's leading portfolio of 8 human challenge study models developed to date and has safely run more human challenge studies than any other company globally

Open Orphan plc (ORPH), a rapidly growing specialist CRO pharmaceutical services company, which is the world leader in the testing of vaccines and antivirals using human challenge studies, is pleased to announce the signing of a contract by hVIVO, a subsidiary of Open Orphan, with the UK Government to develop a COVID-19 (SARS-CoV-2) human challenge study model. The model development involves the manufacture of the challenge virus and the first-in-human characterisation study for this virus. The contract starts immediately and could be worth approximately £10 million to hVIVO depending upon the final number of volunteers that are included in the characterisation study. In addition, the Government has secured the first three slots to test vaccines using hVIVO's COVID-19 challenge study, which we expect start in 2021, each slot reservation has been secured at a cost of £2.5m each bringing the total value of these slot reservations to £7.5m.

The characterisation study, which is expected to complete in May 2021 and will require regulatory and ethical approval, enables identification of the most appropriate dose of the challenge virus for use in future human challenge studies which play a vital role in helping to develop vaccines and antivirals for infectious diseases such as COVID-19.

The study will be sponsored by Imperial College London and conducted by hVIVO at The Royal Free Hospital's specialist research unit in London, under the scrutiny of highly trained scientists and medics. hVIVO will also be expanding its Clinical Operations in London to facilitate work at this site. hVIVO's state of the art, category 2 facility at Queen Mary's Bioenterprise Centre, London, will continue to be used to deliver the Company's traditional challenge study contracts, particularly respiratory syncytial virus (RSV) and is booked to maximum capacity until Summer 2021.

hVIVO has a long history of successfully delivering human challenge studies. The Company, formerly called Retroscreen Virology, was originally established in 1989 as a spin out from Queen Mary University, London. Prior to this hVIVO's founders worked at the common cold unit at Harvard Hospital, near Salisbury. The Salisbury Flu Clinic, as it is more commonly known, has a history of running human challenge studies since 1945. hVIVO has the world's leading portfolio of 8 human challenge study models developed to date and has safely run more human challenge studies than any other company globally. The expertise built up over this long history underpins hVIVO position as the market leader in the provision of human challenge studies.

In our clinical trials going forward, we are also planning to collect data on volunteer's via wearables during clinical trials. Therefore, Open Orphan's data, which may yield valuable digital biomarkers, could be one of the more sought-after datasets by many of the large wearables /smart watch wearables providers around the world. In June 2019, Open Orphan acquired AIM-listed Venn Life Sciences Holdings plc in a reverse take-over and in January 2020 it completed the merger with hVIVO plc in January 2020.
