S0200 Carboplatin With or Without Doxil in Patients With Recurrent Ovarian Cancer

OBJECTIVES:

- Compare overall survival of patients with platinum-sensitive recurrent ovarian
epithelial or primary peritoneal cancer treated with carboplatin with or without
pegylated doxorubicin HCl liposome.

- Compare progression-free survival, confirmed complete response rates, and time to
treatment failure in patients treated with these regimens.

- Compare the toxicity of these regimens in these patients.

OUTLINE: This is a randomized, multicenter study. Patients are stratified according to
disease measurability (elevated CA 125 only vs nonmeasurable disease only with or without
elevated CA 125 vs measurable disease), number of disease sites (2 or fewer vs 3 or more),
and serous tumor histology (yes vs no). Patients are randomized to 1 of 2 treatment arms.

- Arm I: Patients receive carboplatin IV over 15 minutes and pegylated doxorubicin HCl
liposome IV over 1 hour on day 1.

- Arm II: Patients receive carboplatin IV as in arm I. Treatment in both arms repeats
every 4 weeks for a total of 15 courses in the absence of disease progression or
unacceptable toxicity.

Patients are followed at 4 weeks, every 6 months for 3 years, and then annually for 7 years.

PROJECTED ACCRUAL: A total of 900 patients will be accrued for this study within 4 years.

DISEASE CHARACTERISTICS:

- Histologically confirmed ovarian epithelial carcinoma

- Stage III or IV disease at time of initial staging laparotomy

- Primary peritoneal and mixed Mullerian tumors allowed

- No borderline ovarian tumors

- Disease progression or recurrence after a progression-free and platinum-free interval
of 6-24 months after completion of first-line platinum-based chemotherapy (either
single agent or combination therapy)

- Disease progression or recurrence based solely on CA 125 elevation allowed, provided
that one of the following is true:

- Prior baseline CA 125 greater than 35 U/mL and subsequent normalization of no
greater than 35 U/mL must have CA 125 greater than 2 times upper limit of normal
(ULN) on 2 occasions at least 1 week apart

- Prior baseline CA 125 greater than 35 U/mL that never normalized must have CA
125 greater than 2 times the nadir value on 2 occasions at least 1 week apart

- Prior normal baseline CA 125 (no greater than 35 U/mL) must show CA 125 greater
than 2 times ULN on 2 occasions at least 1 week apart

- No known brain metastases
