A Study of DOXIL/CAELYX in Patients With Advanced or Refractory Solid Malignancies Including Patients With Ovarian Cancer

This is a randomized (study medication is assigned by chance), open-label (all people know
the identity of the intervention), single dose, 2-cycle, crossover (method used to switch
participants from one treatment arm to another in a clinical study), and bioequivalence
(biological equivalence of two formulations of a study medication) study of DOXIL/CAELYX in
participants with advanced or refractory solid malignancies (including at least 24
participants with ovarian cancer). This study has an adaptive 2-stage design. Bioequivalence
based on encapsulated doxorubicin will be tested at the end of Stage 1 using data from at
least 24 participants with ovarian cancer. An interim analysis of free doxorubicin will be
performed at the end of Stage 1 using data from 42 participants of all cancer types. The
study may continue into Stage 2 with additional participants of all cancer types; and final
evaluation of bioequivalence for free doxorubicin will be performed at the end of Stage 2.
The study will include a screening phase (within 28 days before the first study medication
administration) followed by the treatment phase consisting of 2 doxorubicin treatment cycles
(28 days each) and an end-of-treatment visit on Day 58. Participants may enter an optional
extension phase after 2 cycles. Safety will be evaluated by the assessment of adverse
events, vital signs, 12-lead electrocardiogram, clinical laboratory testing, and left
ventricular ejection fraction (measurement of the percentage of blood leaving the heart each
time when it contracts) throughout the study. Blood samples for pharmacokinetic analysis
will be obtained from all participants at specified times over 29 days after starting each
study drug administration in Cycles 1 and 2 for determination of plasma concentrations of
encapsulated and free doxorubicin.

Inclusion Criteria:

- Having advanced or refractory solid malignancies (histologically or cytologically
confirmed advanced ovarian cancer failing platinum-based chemotherapy or metastatic
breast cancer after failing approved life prolonging therapies or any solid
malignancy that is metastatic or unresectable, and for which standard treatment is no
longer an option)

- Eastern cooperative oncology group performance status 0 to 2

- Recovered from the acute toxicity (except alopecia and asymptomatic neuropathy) of
any prior treatment

- Participants with prior doxorubicin (or other anthracyclines) or without any prior
anthracylin exposure can also be included

- Agrees to protocol-defined use of effective contraception

Exclusion Criteria:

- Positive history of known brain metastases or leptomeningeal disease (spreading of
cancer throughout the protective membranes covering the brain and spinal cord).
Participants with brain metastases can only be enrolled if the following conditions
are all met: 1) Brain metastases have been treated and stable for more than 4 weeks,
2) No evidence for progression or hemorrhage after treatment, 3) Steroid treatment
was discontinued at least 2 weeks prior to first administration of DOXIL/CAELYX, and
4) Enzyme inducing anti-epileptic medicines were discontinued at least 4 weeks before
first administration of DOXIL/CAELYX

- 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

- Having an uncontrolled infection and uncontrolled concurrent illness including, but
not limited to, poorly controlled hypertension or diabetes, or psychiatric
illness/social situation that may potentially impair the participant's compliance
with study procedures
