Brief Summary:
Fimaporfin (TPCS2a) is a photosensitiser drug being developed by PCI Biotech AS for use in novel Photochemical Internalisation (PCI) technology. PCI technology is designed to enhance the effects of other drugs in a site-specific, light-directed manner and is used to re-localise endocytosed molecules from endosomes to cytosol. This research study is evaluating the use of the PCI Technology in combination with adjuvant and vaccine antigens for safety and induction of immune responses.

    1.1. Male subjects whose partners of childbearing potential do not agree to use an additional acceptable method of contraception.

  2. Female subjects of childbearing potential who do not agree to use 2 acceptable methods of contraception from the time of screening until 3 months after the final dose administration.
  3. Subjects who have a negative result for the test for human leukocyte antigen (HLA)-A2 (Parts B and C only).
