PRIMARY OBJECTIVES: I. Objective tumor response rate (complete plus partial response plus stable disease \> 16 weeks as defined by the Response Evaluation Criteria in Solid Tumors \[RECIST\] criteria) in women with recurrent or refractory advanced ovarian or primary peritoneal cancer. SECONDARY OBJECTIVES: I. Time to disease progression, median survival time, and duration of overall cancer antigen (CA)-125 response. OUTLINE: Patients receive cediranib maleate orally (PO) once daily (QD) every 4 weeks in the absence of disease progression or unacceptable toxicity. After completion of study treatment, patients are followed up at 4 weeks and then every 3 months thereafter.
