Treatment continued until disease progression or unacceptable toxicity.

What was measured

Based on investigator's assessment of response in subjects with measurable lesions. Objective response = complete response + partial response. Complete response = disappearance of all target lesions. Partial response = at least a 30% decrease in the sum of longest diameter of target lesions taking as reference the baseline sum longest diameter.

Analysis population: Intent to treat population with measurable disease at Baseline.

Groups in this outcome

Temozolomide

temozolomide 150 mg/m2/day PO, on 7 consecutive days every 14 days ("7 days on / 7 days off" continuously)

Dacarbazine

dacarbazine 1000 mg/m2 IV, on Day 1 +/- 3 days every 3 weeks

Group identifiers and denominators belong to this outcome only. They may differ in another outcome or in safety reporting.
