The first patient has been dosed in a Phase 1/2a clinical study evaluating a prime-boost vaccine regimen based on Janssen’s AdVac technology and Bavarian Nordic’s MVA-BN technology in female subjects with chronic infections with high risk subtypes of the human papillomavirus (HPV) of the cervix.

This is the first study to enter the human clinical trial stage, under the strategic partnership with Janssen on the development of novel vaccination approaches for HPV, HIV and Hepatitis B. The HPV program aims to develop a therapeutic vaccine for women with persistent HPV types 16 or 18 infection, with a focus on early disease interception.

About the trial

The randomized, double-blind, placebo-controlled, Phase 1/2a study will evaluate the safety, reactogenicity and immunogenicity of monovalent HPV16 and HPV18 Ad26-vectored vaccine components and an MVA-vectored HPV16/18 vaccine component (MVA-BN HPV) in 66 otherwise healthy women with persistent HPV16 or 18 infection of the cervix.

MVA-BN HPV is licensed to Janssen Vaccines & Prevention B.V., who is funding the clinical development of the vaccine regimen. Upon initiation of the Phase 2 portion of the study (vaccination of the fifth subject), Bavarian Nordic will receive a milestone payment of USD 12.5 million, which is expected to be recognized as revenue in the years 2019 to 2021. The company is eligible to receive predefined milestone payments relating to further clinical development and commercialization, together totaling up to USD 162 million in addition to potential royalties on future sales.

“While preventative HPV vaccines have become widely available since their launch only a little over a decade ago, HPV remains the most common sexually transmitted infection resulting in a continued high incidence rate of cervical cancer. Building on our strong clinical experience with the AdVac/MVA-BN vaccine platform from the development of an Ebola vaccine with Janssen, we are excited to explore this new approach, which might represent a significant opportunity to transform the treatment paradigm in cervical and other HPV-induced cancers,” said Paul Chaplin, President and Chief Executive Officer of Bavarian Nordic.
