4. Phase II patients must have detectable BCR-ABL transcript levels meeting at least one of the following criteria: Patient has never achieved a major molecular response, and transcript levels have shown in at least two consecutive measures separated by at least 1 month to have increased by any value, or Achieved a major molecular response that has been lost with an increase in transcript levels by at least 1-log, confirmed in two consecutive analyses separated by at least 1 month, or The patient has received therapy for at least 2 years and does not have a sustained major molecular response, or The patient has received therapy for at least 5 years and does not have a sustained complete molecular response. Patients included in the phase I portion of the study are eligible regardless of their level of BCR-ABL transcripts.
