Vinblastine

RADAR is a multicentre, international, randomised, open-label phase III clinical trial composed of 2 trials running in parallel. Trial 1 will be led and sponsored by University College London (UCL) and conducted in Europe and Australia/New Zealand. Trial 2 will be led by the Canadian Cancer Trials Group (CCTG) and conducted in North America, with CCTG the regulatory sponsor in Canada, and University of Miami the regulatory sponsor and IND holder in the US. Datasets from Trial 1 and Trial 2 will be combined to achieve the total sample size. Data analysis will be performed by UCL and therefore UCL is responsible for the clinicaltrials.gov entry. Eligible patients will be randomised to receive either ABVD or A2VD chemotherapy. An interim PET-CT scan will be performed after 2 cycles of treatment, which will be used to adapt subsequent treatment. Patients will receive a total of 3-4 cycles of chemotherapy and may also receive involved site radiotherapy as consolidation. Patients will be followed up for a minimum of 5 years after treatment.

This phase II trial tests how well personalized reduction of chemotherapy (nivolumab, doxorubicin, vinblastine and dacarbazine) based on circulating tumor deoxyribonucleic acid (ctDNA) evaluation works for treating patients with Hodgkin lymphoma that may have spread from where it first started to nearby tissue, lymph nodes, or distant parts of the body (advanced). Chemotherapy drugs, such as nivolumab, doxorubicin, vinblastine and dacarbazine, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Many types of tumors tend to lose cells or release different types of cellular products including their DNA, which is referred to as ctDNA, into the bloodstream before changes can be seen on scans. Health care providers can measure the level of ctDNA in blood or other bodily fluids and, based on the result, assign patients to a reduced number of chemotherapy treatments or the standard number of chemotherapy treatments. Using ctDNA to assign a personalized reduction of chemotherapy may be effective in treating patients with advanced Hodgkin lymphoma.
