BlueSky Vaccines

Next generation virotherapy against cancer

About us

Our mission

The mission of BlueSky Vaccines is to fully exploit the potential of virotherapy against cancer. The focus of the company is on the development of next generation cancer vaccines based on its proprietary viral vector technology platform. Unique properties of the vector lead to an induction of a strong immune response that is capable of overcoming the immunosuppression created by cancers.

The vector technology combines a conventional vaccine approach (induction of immunity) with an oncolytic approach (specifically destroying cancer cells). It induces a high level of interferon and triggers an TH1-type immune response, activating both innate and adaptive immunity within the tumor bed. Specifically, the vaccine creates a cytokine environment that leads to:

Shift of the cytokine environment from immunosuppressive (TH2) to immune active (TH1).

Inhibition of immunosuppressive regulatory T-cells (Treg).

Activation of natural killer cells (NK).

Activation of cytotoxic T-cells (CTL).

Activation of dendritic cells (DC).


As first target indication for clinical evaluation of the vector, we have chosen human papillomavirus (HPV)-induced cancers. For this purpose, we effectively expressed the HPV-derived tumor antigens E6 and E7 by the delNS106 vector. The resulting delNS106/E6E7 vaccine has demonstrated excellent results and dose-dependent tumor reduction in animal models. Based on the superior data in animal models, this product will now be tested in a clinical phase I setting in HPV infected individuals. Subsequently, phase II trials against cervical lesions, cervical cancer and head and neck cancer will be performed.
