Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment consists of 1x cycle of 3 steps:
Step 1: Day 1 afternoon: oral administration of 10ml photosensitizer liquid containing 10mg of a chlorophyll-derivate extracted from algae, 16-20 hours before LBT (step3)
Step2 : Day 2 morning: 1x 60min Hyperbaric Oxygen Therapy Session (HBOT). Participants will lie supine in a Perry Oxygen Chamber, a clear acrylic plastic pressurised chamber, breathing in through a mask 100% oxygen at 2 atmospheric pressures.
Step 3: Day 2 straight after HBOT: 1x 30min session of Lightbed Photodynamic Therapy (LBT)
LED Light-bed therapy will be applied to the whole body using red light (630-800 nm).
SMS reminders will be sent to participants to assist with adherence to protocol.

HBOT is provided as a clinical service, and all guidelines and eligibility criteria are to be adhered to.
Intervention code [1] 328189 0
Treatment: Devices
Comparator / control treatment
Primary comparator: Patients are their own control. Treatment effectiveness will be assessed by Circulating Tumour Cell (CTC) count by blood test, by which the CTC count (number of CTC/ml) after treatment will be compared to the CTC count before treatment.
Control group
Active
