The protocol is designed to determine the efficacy of temozolomide in preventing the development of new brain metastases within the first year in patients undergoing stereotactic radiation for newly diagnosed brain metastases.

Official Title: | Phase II Study of Gamma Knife Radiosurgery and Temozolomide (Temodar) for Newly Diagnosed Brain Metastases |
Enrollment: | 25 |
Study Start Date: | July 2002 |
Estimated Study Completion Date: | June 2008 |
Estimated Primary Completion Date: | February 2008 (Final data collection date for primary outcome measure) |
This is a phase II study. The primary endpoint is the proportion of patients with newly developed metastases who develop new brain metastases within the first year of undergoing stereotactic radiation combined with the administration of temozolamide within the first year post treatment. Retrospective and prospective studies suggest that 50- 60% of long-term survivors develop new brain metastases. Since it is important to observe all patients recruited for a minimum of a year to measure the primary outcome, traditional phase 2 designs such as Simon's two stage optimal design or the mini-max design are not practical in this case. Survival and QOL are secondary end points. QOL will be measured using the Functional Assessment of Cancer Therapy (FACT -BR). It will be administered at baseline, at week four and every three months for 24 months.
This protocol includes radiosurgery with standard radiation doses (15-24 Gy based upon RTOG 9005). Patient may be registered after radiosurgery as long as Temodar is started within two weeks of radiosurgery.
Beginning within two weeks after radiosurgery: TMZ 200mg/m2 days 1-5 repeat q28 days. Patients who have received prior chemotherapy will receive 150 mg/m2 days 1-5.
Temozolomide is continued until there is disease progression defined by systemic progression or new metastases. If lesion treated with radiosurgery progresses in the absence of new CNS tumors or systemic progression, then TMZ will continue. Temozolomide is discontinued for systemic progression requiring other systemic chemotherapy.
Palliative radiation may be administered to non-CNS sites during protocol treatment, but additional systemic chemotherapy will not be administered until patients progress systemically or until new metastases develop.
