Preclinical studies have proven that the immunostimulatory properties of the delNS-vector “delNS/E6E7” destroy tumours. The vector’s potential for fighting metastases has also been demonstrated in animal models. Moreover, we have shown that delNS/E6E7 eliminates aggressive and incurable papilloma virus induced tumours in horses. Based on these promising results, BlueSky is currently conducting a phase I clinical trial with delNS/E6E7 for tumour elimination and prevention of cervical carcinoma in humans. Subsequently, its efficacy against cervical lesions, cervical cancer as well as head and neck cancer will be assessed in phase II trials.
Interferon also activates endogenous antiviral molecules such as the so-called protein kinase K (PKR). Based on this observation, we have developed “Pekarin”. As a first application, we have successfully tested Pekarin in animal models against influenza viruses. It was found that severity and duration of influenza were both significantly reduced. In principle, Pekarin can be used to fight all viruses. Accordingly, we recently demonstrated its efficacy in the mouse model against COVID-19.
