* Use of an investigational medicine within 21 days or 5 half-lives (whichever is shorter) prior to the first dose of DOXIL/CAELYX
* Any major surgery, radiotherapy, or immunotherapy within the last 21 days. Chemotherapy regimens with delayed toxicity within the last 3 weeks (or within the last 6 weeks for prior nitrosourea or mitomycin C)
* Unstable angina or myocardial infarction within the preceding 12 months; congestive heart failure or any history of uncontrolled cardiac disease
