In this context, the present study shall demonstrate whether application of P16_37-63 in a vaccination approach is associated with the induction of peptide-related toxicity. Hence, the study marks the first step towards the application of P16_37-63 in humans, as it provides information on the safety of P16_37-63 as vaccination agent for the first time. Moreover, the study shall provide initial information, whether vaccination with P16_37-63 can induce p16INK4a -specific immune responses in patients with advanced HPV- and p16INK4a -positive cervical, vulvar, vaginal, penile, anal or head and neck cancer. Thus, it shall provide information, whether P16_37-63 has the potential to elicit peptide-specific immune responses and therefore represent a suitable target for the induction of tumor antigen-specific immune responses in this population.
