Adenocarcinoma of the Prostate - Hormone Refractory Prostate Cancer - Recurrent Prostate Cancer |
| Purpose: |
|
This phase I/II trial studies the side effects and best dose of lenalidomide when given
together with cyclophosphamide and to see how well they work in treating patients with
previously treated hormone-refractory prostate cancer. Lenalidomide may stop the growth of
prostate cancer by blocking blood flow to the tumor. Drugs used in chemotherapy, such as
cyclophosphamide, work in different ways to stop the growth of tumor cells, either by
killing the cells or by stopping them from dividing. Giving lenalidomide together with
cyclophosphamide may kill more tumor cells

| Study Summary: |
|
PRIMARY OBJECTIVES:
I. To determine the maximum tolerated dose (MTD) and the dose limiting toxicities (DLT) of
lenalidomide administered in combination with oral cyclophosphamide.
SECONDARY OBJECTIVES:
I. To evaluate the objective prostate-specific antigen (PSA) response (50% decrease in PSA
levels sustained for at least 4 weeks) as defined by PSA working group criteria; or a
decrease in absolute PSA or a decrease in PSA velocity, increase in PSA doubling time,
duration of any responses.
II. To explore the anti-tumor activity of the combination of lenalidomide plus oral
cyclophosphamide in patients with previously treated hormone refractory prostate cancer.
III. To evaluate baseline and change of quality of life, particularly, bone pain and
analgesic consumption, of the patients on this combination chemotherapy.
TERTIARY OBJECTIVES:
I. To determine whether related cytokines and biomarkers (serum levels of tumor necrosis
factor-alpha, basic fibroblast growth factor, vascular endothelial growth factor [VEGF], T
cell inhibitory activity, phytohemagglutin [PHA] and interleukin [IL]-2, mononuclear cell
isolation, VEGF, basic fibroblast growth factor [bFGF], interleukin [IL]-6) can help predict
response to patients undergoing treatment with lenalidomide and cyclophosphamide.
OUTLINE: This is a phase I, dose-escalation study of lenalidomide followed by a phase II
study.
Patients receive lenalidomide orally (PO) once daily (QD) on days 1-21 and cyclophosphamide
PO QD on days 1-28. Treatment repeats every 28 days for at least 4 courses in the absence of
disease progression or unacceptable toxicity. Treatment modifications may apply according to
response.
After completion of study treatment, patients are followed up periodically.
