Efficacy and Safety Study of SyB L-0501 for Patients With Chronic Lymphocytic Leukemia

NCT ID: NCT02042911

Last Updated: 2017-02-01

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE2
• Total Enrollment: 10 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2013-01-31
• Study Completion Date: 2015-06-30

Brief Summary

The purpose of this study is to investigate safety and efficacy of SyB L-0501 after 2-day intravenous infusion at a dose of 100 mg/m2/day to patients with chronic lymphocytic leukemia.

Conditions

Chronic Lymphocytic Leukemia

Study Design

• Allocation Method: NA
• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

SyB L-0501

Group Type: EXPERIMENTAL

SyB L-0501

Intervention Type: DRUG

SyB L-0501 is administered at 100 mg/m2/day by intravenous infusion on Day 1 and Day 2 followed by 26 days of monitoring. This is considered to be one cycle and may be repeated up to 6 cycles. Dose administration can be delayed or discontinued from the second cycle as necessary according to adverse events and the results of monitoring during the previous cycle, but dose reduction is permitted from the 3rd cycle.
