Summary
Brief summary
A Phase II study of efficacy and safety of Pegasys® in patients with chronic myeloid leukaemia (CML) in complete or near complete cytogenetic remission but persisting molecular positivity at 600 mg or maximum tolerated dose of Glivec

Patients with Ph+ve CML with complete or near complete cytogenetic responses to Glivec® at 600 mg or maximum tolerated dose, but with persisting molecular positivity.

Primary Objective: To assess whether adding Pegasys® to Glivec® in these patients improves molecular response status (by PCR quantification of bcr-abl transcripts)
