    ABSTRACT: To conduct a phase I trial to determine the safety and toxicity profile of a novel immunomodulatory drug, lenalidomide, in recurrent ovarian and primary peritoneal cancer. The secondary objective is to evaluate the efficacy profile and quality of life (QOL) parameters in patients receiving this treatment. Patients with recurrent ovarian or peritoneal cancer who received standard staging surgery and at least one prior platinum-based chemotherapy regimen were treated with single-agent oral lenalidomide 25 mg daily for 21 days of a 28-day cycle. Toxicities were monitored by patient report, physical exam, and laboratories. Response was assessed by imaging, physical exam, and CA-125. Therapy was discontinued with disease progression and/or unacceptable toxicity. 20 patients with recurrent ovarian or peritoneal cancer were enrolled and received 70 completed 28-day cycles and 10 partial cycles of lenalidomide therapy. The majority of adverse events were grades 1-2, including fatigue (25/80 cycles), nausea/vomiting (23/80), constipation (13/80), abdominal pain (17/80), rash (12/80), neutropenia (12/80), and anemia (12/80). Grade 3 toxicities occurred in 12 of 80 cycles (14%) and no grade IV toxicities were observed. Eleven patients completed > or = 2 cycles and were evaluable for response. Nine achieved stable disease (SD) of at least 3 months, with four patients maintaining SD for > 6 months. The mean time to progression was 5.8 months (range 2-12 months). Overall, oral lenalidomide was well tolerated and may have some activity as a single agent in this heavily pre-treated population. Further studies combining lenalidomide with cytotoxic treatments may be warranted in this disease setting.
