About

The purpose of this study is to evaluate the neuroprotective effect of PROCRIT (epoetin alfa, a glycoprotein that stimulates red blood cell production) versus placebo in patients with cancer who develop chemotherapy-induced peripheral neuropathy due to combination Taxane and Platinum-Based treatment.

Full description

Peripheral neuropathy is a debilitating disease of the nerves which can be a dose-limiting toxicity of chemotherapeutic agents. The symptoms of peripheral neuropathy can lead to considerable patient distress and discomfort, discontinuation of chemotherapy, and limitations regarding the selection of future chemotherapeutic regimens. Symptoms such as numbness, weakness, burning pain (especially at night), and loss of reflexes may take months before they improve and permanent deficits may remain. Epoetin alfa, already used in the treatment of chemotherapy-induced anemia, has been shown to have neuroprotective effects in preclinical studies. The purpose of this randomized (patients are assigned different treatments based on chance), double-blind (neither the patient nor the physician knows whether drug or placebo is being taken, or at what dosage), placebo-controlled study is to evaluate the neuroprotective effect of PROCRIT (epoetin alfa) administered once every week in patients with cancer who develop chemotherapy-induced peripheral neuropathy due to treatment with combination Taxane and Platinum-Based chemotherapy. Patients will receive injections subcutaneously or intravenously of either epoetin alfa or placebo once weekly for up to 18 weeks. Doses may be adjusted in the range of 20,000 to 60,000 Units once a week, depending on the patient's hemoglobin levels. Safety evaluations will be conducted throughout the study at specified intervals and will consist of assessment of laboratory tests (Hemoglobin level, Complete Blood Count (CBC), Blood Chemistries), vital signs, physical examinations and occurrence and severity of adverse events. In addition, the occurrence of anti-erythropoietin antibodies at baseline and study completion/early withdrawal will be evaluated in patients who received PROCRIT (Epoetin alfa) after database lock and unblinding has occurred. The primary measure of effectiveness is the change at Week 12 in the National Cancer Institute Common Toxicity Criteria (NCI CTC) neuropathy score. The study hypothesis is that epoetin alfa will be more effective in the treatment of chemotherapy-induced peripheral neuropathy than placebo as measured at Week 12 by the National Cancer Institute Common Toxicity Criteria (NCI CTC) neuropathy score. Patients will receive injections subcutaneously (SC, under the skin) or intravenously (IV, in a vein) of either epoetin alfa or placebo once weekly for up to 18 weeks. Doses may be adjusted depending on the patient's hemoglobin levels to the maximum 60,000 Units once a week. The minimum dose can be 20,000 Units once a week.
