Chronic Lymphocytic Leukaemia or CLL, is the most common form of leukaemia. It's a disease which kills. The most common treatment is with chemotherapy. If that doesn't work, most patients can only expect to live for another few years at most.

But there are dramatic developments with new targeted treatments which are less toxic than conventional chemotherapy. In this programme, reporter Simon Cox follows a medical trial based at St James' hospital in Leeds which uses a unique combination of drugs designed to defeat the cancer. It's the last hope for many patients but will it work? Can researchers find a cure?
