A randomised double blind phase 2 trial of whole brain radiotherapy with or without vandetanib in metastatic melanoma with brain metastases.
The aim is to compare whole brain radiotherapy (WBRT) with or without vandetanib in the treatment of patients with brain metastases from melanoma, in terms of progression free survival, overall survival and safety and tolerability of vandetanib in combination with radiotherapy.
Target recruitment: 6 patients in a safety cohort plus 80 patients in the randomised trial.
Current status: Closed to recruitment. All patients are now off trial.
Unfortunately research teams across the country found it more difficult than expected to find patients who are suitable for the study and for whom the trial is the best treatment option for their cancer. After 13 months of recruitment the Trial Steering Committee who oversee the trial reviewed the study’s progress carefully and agreed to close recruitment to the RADVAN trial in April 2014, before the total number of patients needed to finish the study was recruited.
A substantial amendment has been submitted to the ethics committee and regulator to close the study earlier than planned - the trial is now expected to close in December 2014. Follow up of participants in the study will continue as planned under the original study protocol until the study ends.
The researchers intend to publish the study results that we have in a medical journal for other doctors to read so that they can learn from our experience of the study.
