Details and patient eligibility

About

The purpose of this Australian study was to assess the efficacy and safety of nilotinib 300mg twice daily in patients with chronic myeloid leukemia chronic phase who were intolerant but responsive to 1st line treatment with imatinib or dasatinib. Eligible patients have been previously treated with imatinib or dasatinib for at least 3 months and are experiencing non-hematologic toxicity whilst having documented responses that meet PBS authority for 1st line treatment of CML without current MR4.5.

Full description

The study was planned to enroll 130 patients to achieve the sample size requirement for a meaning full conclusion. Study got terminated with 20 patients because of slow recruitment. Therefore, due to small sample size, the results cannot be considered clinical significant.

Enrollment: 20 patients

Sex: All

Ages: 18+ years old

Volunteers: No Healthy Volunteers

3. Patient has documented Molecular Response (MR) 4.5 at the time of study entry
4. Patients with atypical BCR-ABL transcript not quantifiable by standard RQ-PCR.
