DBPR807 can significantly suppress tumor growth, prevent distant metastasis, reduce angiogenesis, normalize tumor microenvironment and promote cytotoxic T-cell infiltration. In various HCC models, DBPR807 itself can prolong overall survival as effectively as marketed anti-angiogenic agent sorafenib and immune checkpoint inhibitor anti-PD-1 Ab. What’s more, its combination therapy with either sorafenib or anti-PD-1 Ab can extend life expectancy even more significantly than aforementioned monotherapy.

Effectively inducing cytotoxic T cell expansion has been a critical challenge in vaccine development. To address this challenge, an entirely biodegradable polymeric nanoshell was invented to couple antigensadjuvants for safepotent immune potentiation. The invention has been adopted for precision anticancer vaccine, broadly reactive influenza vaccine,an effective vaccine MERS-CoV.
