KORTUC

Randomised phase II trial testing efficacy of intra-tumoural hydrogen peroxide as a radiation sensitiser in patients with locally advanced/recurrent breast cancer.

Disease site: Breast cancer

Treatment modality: Radiotherapy +/- Radiation sensitiser

Status: Open to recruitment

Trial details

KORTUC phase II is a multi-centre, non-blinded, randomised trial with two groups comparing radiotherapy plus/minus a novel radiation sensitiser (intra-tumoural injections of hydrogen peroxide), in patients with primary or recurrent locally advanced breast cancer requiring high dose radiotherapy for lifetime control of moderate or severe morbidities.

This is a multi-centre trial involving 5 centres in the UK (The Royal Marsden NHS Foundation Trust, Royal Alexandra Hospital/Beatson Oncology Centre, The Christie NHS Foundation Trust, Royal Cornwall NHS Trust, University Hospitals of North Midlands NHS Trust), with plans to expand to India. 184 patients will be recruited over a 3 year period. Patients will receive radiotherapy alone or radiotherapy + KORTUC and will be followed up for a period of 2 years.
