Based on the body surface area calculated before treatment in each cycle, the dose is calculated for each patient according to the dose level specified by the Patient Enrollment Center (0.7mg/m2, 1.0 mg/m2 or 1.3 mg/m2). JNJ-26866138 is intravenously administered once daily, twice weekly for 2 weeks (Days 1, 4, 8, and 11), followed by a 10-day rest period (Days 12 to 21). This is considered one cycle (21 days), and treatment is repeated up to 6 cycles in patients expected to show a response.
