Two Major Ongoing Externally Funded Research Projects
- 5-Aminolevulinic Acid-based Photopheresis (2015-2020, HSØ & DNK)
This project uses the PDT principle to develop a technology to photodeplete highly proliferative/activated T cells that are involved in malignant and non-malignant diseases. There are two ongoing clinical trials in patients with graft versus host disease, cutaneous T cell lymphoma or Crohn’s disease.
- Nanoscintillator-Porphyrin Complexes for Bimodal RadioPhotoDynamic Therapy (2016-2019, EuroNanoMed) This EU project has been developing a bimodal cancer treatment modality by combining two clinically used radiotherapy and photodynamic therapy, mediated by theranostic nanoparticles (composed of nanoscintillators and photosensitisers). Upon exposure to ionizing radiation the nanoscintillators (polysiloxane core/terbium oxide) transfers the X-ray energy to the tethered photosensitiser that produces cytotoxic singlet oxygen. With this novel therapeutic approach the problem of limited visible light penetration into solid tumour tissue in PDT can be solved. In addition, this new modality will allow treatment of deep tumours with lower radiation doses than those in conventional radiotherapy.
