Study Description
Brief Summary:
This study will determine the response rate of daily low dose interferon-alpha-2b in patients with metastatic or unresectable clear cell renal cell carcinoma.

Condition or disease Intervention/treatment Phase
Renal Cancer Drug: Interferon Alpha-2b Phase 2

Detailed Description:

Rationale: Interferon has long been used as a therapy for renal cell carcinoma. However, optimal dosing schedules have not been identified and patients have been relegated to receiving the highest possible doses for prolonged periods of time. This high-dose approach often leads to serious adverse effects from toxicity that limits the usefulness and patient tolerance of this treatment. No formal study has determined the relationship if any between the maximal tolerated dose (MTD) and the biological effective dose of interferon alpha-2b. The current study seeks to fill that gap by gathering research information about different doses of interferon alpha-2b and correlating with measurements of JAK/STAT in the blood. Validation of correlative studies to determine optimum biologic dosing are needed so that therapy may be adjusted appropriately rather then the current approach of maximizing dose. In addition, a trial of low dose daily administered interferon-2b has not been carried out in the current era with refined histologic classification and modern CT imaging scanning. As this therapy potentially has wide applicability, definite response rates need to be documented.

Purpose: The purpose of this study is to assess the response rate of daily low dose interferon-2b in patients with metastatic or unresectable clear cell renal carcinoma. The duration of the response and overall survival will be determined in study participants. This study will also evaluate JAK/STAT, two types of kinases or enzymes involved in an intracellular signaling process associated with cancer growth, in peripheral blood mononuclear cells over the course of interferon alpha-2b dose escalation. Researchers will examine in a preliminary manner the correlation between clinical response, toxicity, and JAK/STAT signal transduction. Progression free survival and rate of stable disease will also be determined in a preliminary manner.

Treatment: Study participants will receive interferon alpha-2b. This drug will be self-administered daily through injections into the skin. The dose level of interferon alpha-2b will be increased each week into study treatments. For the first three weeks and approximately monthly thereafter, patients will have blood drawn three hours following interferon alpha-2b administration to measure JAK/STAT. Toxicity from study treatments will be closely monitored in patients during clinics visits. Supportive care therapies will be given throughout the study. Treatments will be discontinued due to disease growth or unacceptable side effects.
