A Study of JNJ-30979754 (Decitabine) in Patients With Myelodysplastic Syndrome

A Phase I/II Clinical Study of JNJ-30979754 (Decitabine) in Patients With Myelodysplastic Syndrome

The purpose of this study is to to determine the recommended dose level of JNJ-30979754 (decitabine) as well as to assess the safety and effectiveness in patients with Myelodysplastic Syndrome (MDS).

This is an open-label (both physician and patient know the name and dosage of drug), multi-center study. This study consists of two parts, Phase I and Phase II. In Phase I, approximately 9 participants will be enrolled ie, 3 participants for dose level 1 (15 mg/m2 of JNJ-30979754) and 6 participants for dose level 2 (20 mg/m2 of JNJ-30979754). Once the tolerability of 20 mg/m2 is confirmed additional 30 participants will be included to receive 20 mg/m2 and approximate total participants in Phase II will be 36. This study will include screening period (within 14 days prior to the day of initial administration of Cycle 1) and dosing period (1 cycle consists of administration of study medication for first 5 consecutive days + rested for 23 days; ie, total 28 days). Cycles will be reapeated in participants in whom decitabine was expected to be effective. Safety evaluations will include assessment of adverse events, vital signs, body weight, clinical laboratory tests: hematology, blood biochemistry and urinalysis, cardiopulmonary function tests: ECG, chest X ray and oximeter analysis.
