Atorvastatin Calcium and Celecoxib in Treating Patients With Rising PSA Levels After Local Therapy for Prostate Cancer

OBJECTIVES:

Primary

- To determine the effect on the biological activity, as assessed by prostate-specific
antigen (PSA) response, of atorvastatin calcium and celecoxib in patients with D0
prostate cancer.

Secondary

- To document the safety and feasibility of atorvastatin calcium and celecoxib in patients
with early-stage prostate cancer.

- To evaluate the effects of the combination of atorvastatin calcium and celecoxib on
nuclear factor-kB (NFkB), extracellular signal-regulated kinase (ERK), prostaglandin E2
(PGE2), and IL6 in peripheral blood mononuclear cells (PBMC).

OUTLINE: This is a multicenter study.

Patients receive oral atorvastatin calcium once daily and oral celecoxib twice daily on days
1-28. Treatment repeats every 28 days for 6 courses in the absence of disease progression or
unacceptable toxicity.

Patients may undergo blood sample collection at baseline and after completion of study
therapy for correlative studies.

After completion of study therapy, patients are followed up every 3 months for 2 years.

DISEASE CHARACTERISTICS:

- Histologically confirmed prostate cancer

- Stage D0 disease

- Tumor originally diagnosed as being limited to the prostate and now having a
rising prostate-specific antigen (PSA) after definitive local therapy

- Must have undergone local treatment via prostatectomy or radiotherapy

- PSA values must be ≥ 0.2 ng/mL as determined by 2 measurements, ≥ 1 month apart
and ≥ 6 months after prostatectomy

- PSA values must be ≥ 2.0 ng/mL as determined by 2 measurements, ≥ 1 month apart
and ≥ 6 months after radiotherapy

- The first two PSA values along with a third value must all be rising (i.e., there
must be an overall rising trajectory, such that the third value cannot be lower
than the first value)

- No metastatic disease by baseline bone scan and CT scan of the abdomen and/or pelvis

PATIENT CHARACTERISTICS:

- Life expectancy ≥ 6 months

- ECOG performance status 0-2

- WBC ≥ 3,500/µL

- ANC ≥ 1,500/µL

- Platelet count > 100,000/µL

- Hemoglobin > 10 g/dL

- Serum creatinine < 1.5 mg/dL OR creatinine clearance > 50 mL/min

- Total bilirubin normal

- SGOT and/or SGPT normal

- No serious concomitant systemic disorder that, at the discretion of the investigator,
would compromise the safety of the patient or compromise the patient's ability to
complete the study

- No second primary malignancy within the past 5 years except adequately treated in situ
carcinoma (e.g., non-melanomatous carcinoma of the skin) or other malignancy with no
evidence of recurrence

- No active clinically significant infection requiring antibiotics

- No history of coronary artery disease

- No myocardial infarction within the past 6 months

- No sulfa allergy

- No history of gastrointestinal bleeding

PRIOR CONCURRENT THERAPY:

- See Disease Characteristics

- No prior hormone-ablative treatment

- Prior neoadjuvant hormone-ablative therapy allowed provided it was completed ≥ 3
months ago

- More than 4 weeks since prior herbal products with hormonal activity such as soy, saw
palmetto, or PC-SPES

- No prior or concurrent nonsteroidal anti-inflammatory drug (NSAIDS) for 7 consecutive
days

- No COX-2 inhibitor and/or statin within the past 6 months

- No concurrent warfarin or any other anticoagulant, calcitriol, fibric acid
derivatives, lipid-modifying doses of niacin, or strong cytochrome P450 3A4 inhibitors
(e.g., cyclosporine, erythromycin, clarithromycin, and azole antifungals) or inducers
(e.g., St John wort)

- No other concurrent anticancer agents or therapies including chemotherapy, hormonal
therapy, radiotherapy, or experimental therapy
