| Scientific title | A prospective randomised trial comparing temozolomide with standard nitrosourea-based chemotherapy (PCV [procarbazine, CCNU, vincristine]/BCNU [bis-chloronitrosourea]) in the treatment of recurrent WHO astrocytic tumours grades III and IV (anaplastic astrocytoma and glioblastoma multiforme) |
| Study acronym | BR12 |
| Study objectives | BR12 is a randomised trial which compares standard PCV chemotherapy with two temozolomide schedules in patients with histologically confirmed recurrent World Health Organisation (WHO) Grade III or IV astrocytic tumour who have had primary radiotherapy (but no prior chemotherapy). More details can be found at: http://www.ctu.mrc.ac.uk/research_areas/study_details.aspx?s=7 |
| Ethics approval(s) | No ethics information required at time of registration. |
| Health condition(s) or problem(s) studied | Astrocytic tumours (anaplastic astrocytoma and glioblastoma multiforme) |
| Intervention | 1. Temozolomide according to one of two schedules: a. Temozolomide, 200 mg/m^2 orally (po) days one to five b. Temozolomide, 100 mg/m^2 po days one to 21 2. PCV chemotherapy (CCNU 100 mg/m^2 po day one, Procarbazine 100 mg/m^2 po days one to ten, Vincristine 1.5 mg/m^2 (max 2 mg) intravenous (iv) day one) |
| Intervention type | Drug |
| Phase | Not Specified |
| Drug / device / biological / vaccine name(s) | Procarbazine, CCNU, vincristine, bis-chloronitrosourea, temozolomide |
| Primary outcome measure(s) |
The primary objective of the trial is to evaluate, in a group of patients representative of those who are considered for chemotherapy outside of trials, the potential benefit of temozolomide compared to PCV with respect to survival in patients with recurrent malignant glioma. |
| Key secondary outcome measure(s) |
In addition, the treatments will be compared with respect to the following secondary outcome measures: survival free from progression (confirmed radiologically), and health-related quality of life. A further objective is to evaluate the comparative efficacy (progression-free survival) and toxicity of the two different temozolomide schedules. |
