Outcome Measures
Primary Outcome Measures
- To investigate the effects of the co-administration of imatinib on the pharmacokinetics of acetaminophen / paracetamol [Day 1, day 2 -7, Day 8]
- To investigate the pharmacokinetic characteristics of imatinib at steady state in CML-CP patients following 400 mg dosing co-administered with acetaminophen [Day 1, Day 2-7, Day 8]

-
Patient had major surgery within 4 weeks prior to study entry, or who have not recovered from prior major surgery
-
Patients with an ECOG Performance Status Score ≥ 3
-
Patients with International normalized ratio (INR) or partial thromboplastin time (PTT) > 1.5 x IULN, with the exception of patients on treatment with oral anticoagulant
-
Patients with known positivity for human immunodeficiency virus (HIV)
-
baseline testing for HIV is not required
-
Patients with any significant history of non-compliance to medical regimens or with inability to grant a reliable informed consent
-
Patients with identified sibling donors where allogeneic bone marrow transplant is elected as first line treatment
-
Patients who are chronic users of acetaminophen or medications containing acetaminophen.
-
Patients who received acetaminophen or medications containing acetaminophen within 72 hours prior to study entry.
