4. Less than 1 week since surgery (excluding minimal procedures, e.g. vascular access device insertion)
5. Concomitant infection
6. Subjects with other severe concurrent disease that in the judgement of the investigator would make the subject inappropriate for entry into this study

8. Contraindication for photosensitizer
9. Porphyria or other diseases exacerbated by light
10. Known hypersensitivity to verteporfin for injection (VFI) or to any of the excipients
11. Known allergies to porphyrins
12. Tumours known to be eroding into a major blood vessel in or adjacent to the illumination site
13. On-going therapy with a photosensitizing agent
14. Enrolment in another therapeutic clinical study within 3 months prior to randomization and throughout the study.
15. Subjects with a history of CTCAE v4 grade 3 or greater or persistent (>1 separate episode or symptoms lasting more than 3 months after initiation of medical intervention) grade 2 proctitis attributed to radiation.
