A Phase II Study of Temozolomide and Radiation Therapy in Patients With Brain Metastasis From Non-small Cell Lung Cancer (NSCLC)


OBJECTIVES:

Primary

- Determine the intracranial response rate in patients with brain metastasis secondary to
non-small cell lung cancer treated with whole brain radiotherapy and temozolomide.

Secondary

- Determine the time to radiological progression in patients treated with this regimen.

- Determine the time to neurological progression (confirmed by magnetic resonance imaging
(MRI)) in patients treated with this regimen.

- Determine the overall survival of patients treated with this regimen.

- Determine the toxicity of this regimen in these patients.

OUTLINE: This is a multicenter study.

Patients undergo whole brain radiotherapy once daily, 5 days a week, for 2 weeks (10
fractions). Patients also receive concurrent oral temozolomide once daily on days 1-14.

Beginning 3 weeks after the completion of chemoradiotherapy, patients receive oral
temozolomide once daily on days 1-5. Treatment repeats every 28 days for up to 6 courses in
the absence of neurologic (Central Nervous System, CNS) progression or unacceptable
toxicity.

Patients were followed every 3 months for 2 years.

ACCRUAL: A total of 26 patients were accrued for this study.

administration of study drug at scheduled dosing interval or to allow treatment with
study drug at a higher dose

Type of Study:

Interventional

Study Design:

Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Outcome Measure:

Number of Patients With Intracranial Response

Outcome Description:

Response was assessed per Response Evaluation Criteria in Solid Tumor (RECIST) by brain MRI in the 21 eligible and treated patients.Complete response (CR): complete disappearance of the clinically detectable malignant brain metastasis(es) being followed on MRI scan off corticosteroids and a stable or improving neurologic exam. Partial response (PR): greater than or equal to a 50% reduction in the sum of the product(s) of the maximal cross-sections on MRI scan with a stable or decreasing dose of corticosteroids and a stable or improving neurologic exam. Response = CR + PR

Outcome Time Frame:

assessed every cycle while on treatment, then every 3 months for 2 years

Safety Issue:

No
