Scientific titleA randomised double blind phase 2 trial of whole brain radiotherapy with or without vandetanib in metastatic melanoma with brain metastases
Study acronymRADVAN - XRT +/vandetanib in CNS melanoma
Study objectivesThis is a randomised, double-blind, placebo-controlled, multi-centre phase 2 trial. Eighty patients (forty in each of two arms) will be randomised 1:1 between radiotherapy with placebo or radiotherapy with vandetanib, with stratification for recursive partitioning analysis (RPA) score (2 levels, RPA 1 and RPA 2). Patients will receive three weeks of either vandetanib 100mg once daily or placebo, starting 4 days (+/- 1 day) before whole brain radiotherapy (30 Gy in 10 fractions). The main study will be preceded by a safety run in phase (involving 6 patients) to confirm the tolerability of vandetanib 100mg with radiotherapy at 30 Gy in 10 fractions in this patient group. Tolerability will be defined as no study treatment related toxicity of grade 3 or more (CTCAE version 4.0) in at least 5 out of the 6 patients in the safety run in phase at 30 days post end of study treatment. Patients will continue to be reviewed on study until progression of brain metastases (by RECIST version 1.1) or 12 months post randomisation into study, whichever comes first, and thereafter will be followed up for survival alone.
Ethics approval(s)11/SC/0282
Health condition(s) or problem(s) studiedTopic: National Cancer Research Network; Subtopic: Melanoma; Disease: Melanoma
InterventionEighty patients (forty in each of two arms) will be randomised 1:1 between radiotherapy with placebo or radiotherapy with vandetanib, with stratification for RPA score (2 levels, RPA 1 and RPA 2). The main study will be preceded by a safety run in phase involving 6 patients on radiotherapy with vandetanib.

Radiotherapy will be administered via parallel opposed lateral beams dosed to the midpoint as 30 Gy in 10 fractions over 2 weeks (i.e. over 10-14 days, to allow for weekends), starting 4 days (+/- 1 day) after commencing study drug.

Vandetanib/Placebo: Patients in the safety run-in phase will all receive vandetanib 100 mg OD, starting 4 days (+/- 1 day) before whole brain radiotherapy (WBRT) and continuing for 21 days in total. Patients in the randomisation phase will receive vandetanib/placebo, starting 4 days (+/- 1 day) before WBRT and continuing for 21 days in total. No study treatment is to be given beyond day 21, even if any doses are missed during this period.
