In response to urgent medical and societal needs for novel immunotherapies for cancer and chronic infections and for prophylactic vaccination, optimised delivery systems for vaccine targeting to dendritic cells will be developed and clinically evaluated. The approach will rely on two new antigen delivery vectors, the detoxified adenylate cyclase toxoid (ACT) and the porcine parvovirus-like particles (PPV-VLP) which were recently shown to target dendritic cells very efficiently and specifically, allowing highly efficient presentation of delivered antigens to T cells. These vaccine vectors enable the induction of strong, specific and protective immune responses and have an established record of safety and efficacy in preclinical animal models. Under this project, academia experts in immunology, vaccinology, molecular biology and structural biology have joined forces with toxicologists, clinicians and vaccine production experts of two companies, in order to translate these novel vaccine technologies from research into clinical application. Based on the preclinical record of ACT-based vaccines in animal models, the leap into safety and efficacy Phase l/ll human clinical trial will be made with an ACT-based construct delivering the tyrosinase A.2 epitope as a therapeutic vaccine for metastasic melanoma.
Simultaneously to GMP batch production, development and clinical testing, in-depth analysis of the cellular and molecular mechanisms and of the structural basis of ACT interaction with dendritic cells will be conducted, by placing particular emphasis on gaining new knowledge for further improvement of the delivery capacity of the ACT molecule towards enhanced efficiency and broader versatility in clinical use. The PPV-VLP vector will be developed in parallel by defining its cellular receptor and trafficking inside dendritic cells,preclinical efficacy and toxicology, in order to bring this alternative vaccine carrier to the level of clinic.
