Condition(s) targeted: Renal Cell Cancer; Stage IV Renal Cell Cancer

Intervention: celecoxib (Drug); recombinant interferon alfa-2b (Biological); polymerase chain reaction (Other); laboratory biomarker analysis (Other); reverse transcriptase-polymerase chain reaction (Other); immunologic technique (Other); immunohistochemistry staining method (Other); flow cytometry (Other)

Phase: Phase 2

Status: Completed

RATIONALE: Celecoxib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Recombinant interferon alfa-2b may interfere with the growth of cancer cells and slow the growth of kidney cancer. Giving celecoxib together with recombinant interferon alpha-2b may kill more tumor cells and be an effective treatment for metastatic kidney cancer. PURPOSE: This phase II trial is studying how well giving celecoxib together with recombinant interferon alfa-2b works in treating patients with metastatic kidney cancer who have undergone surgery.

Clinical Details

Official title: A Phase II Trial of Celecoxib Plus Interferon Alpha in Metastatic Renal Cell Carcinoma Patients With 3+ COX-2 Tumor Immunostaining

Study design: Endpoint Classification: Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome: Objective Response Rate Assessed by RECIST Criteria.

Secondary outcome:

Overall Survival

Duration of Response

Progression-free Survival

Number of Patients With Statistically Significant Change in Cellular Immune Parameters From Baseline to 2 Months

Detailed description: PRIMARY OBJECTIVES: I. To estimate the objective response rate of interferon alpha plus celecoxib in metastatic RCC patients with 3+ COX-2 tumor immunostaining. SECONDARY OBJECTIVES: I. To compare cellular immune parameters in metastatic RCC patients with 3+ COX-2 tumor immunostaining to patients with < 1+ tumor immunostaining. II. To evaluate the effect of celecoxib and interferon alpha therapy on cellular immune parameters in metastatic RCC patients with 3+ COX-2 tumor immunostaining. OUTLINE: Patients receive oral celecoxib twice daily and recombinant interferon alpha-2b subcutaneously, once daily, 5 times a week. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.


Minimum age: 18 Years. Maximum age: N/A. Gender(s): Both.



- Patients must have histologically-confirmed metastatic renal cell carcinoma

- Patients must have 3+ (on a scale of 0 to 3+) COX-2 staining in >= 10% of the RCC

tumor cells from baseline tumor tissue

- Patients may have received any number of prior non-cytokine systemic therapies for

metastatic RCC

- Patients must have undergone nephrectomy (radical or partial)

- All patients must be at least 2 weeks from prior systemic therapy, radiation or major

- Ability to understand and the willingness to sign a written informed consent document

- Patients with any untreated CNS metastases are excluded from this clinical trial;

patients who have undergone surgery and/or radiation for CNS metastases are eligible for enrollment if they do not have CNS metastases that have not been treated, are at least 2 weeks from treatment of CNS metastases without evidence of CNS disease progression (stable CT scan or MRI) and are off steroids; all patients must undergo an MRI or infused CT scan of the brain prior to enrollment

well as physiologic replacement doses of steroids are permitted)

reaction requiring steroids or epinephrine or any degree of airway compromise) to sulfonamide or sulfonamide derivatives drugs are excluded; this includes, but is not limited to, sulfonamide antibiotics such as sulfadiazine, sulfamethoxazole, sulfisoxazole and sulfacetamide and sulfonamide derivatives such as celecoxib, valdecoxib, diuretics (HCTZ, furosemide), sulfonylureas, dorzolamide and sumatriptan

- Karnofsky >= 70%
