paclitaxel with or without gemcitabine in treating women with advanced breast cancer

Conditions: Breast Cancer

Summary: rationale: drugs used in chemotherapy use different ways to stop tumor cells from dividing so they stop growing or die. combining more than one drug may kill more tumor cells. it is not yet known if paclitaxel is more effective with or without gemcitabine for advanced breast cancer. purpose: randomized phase iii trial to study the effectiveness of paclitaxel with or without gemcitabine in treating women who have advanced breast cancer.

objectives: i. compare overall survival of patients with unresectable, locally recurrent, or metastatic breast cancer treated with paclitaxel with or without gemcitabine. outline: this is a randomized, multicenter study. patients are randomized to one of two treatment arms. patients receive paclitaxel with or without gemcitabine. treatment continues every 21 days in the absence of disease progression. patients are followed every 2-4 months for 2 years after active treatment. projected accrual: not specified national cancer institute (nci) registered this trial with eli lilly as sponsor. nci did not update the record when the trial completed. in june 2012, nci transferred the trial to lilly's clinicaltrials.gov account and lilly updated the record with the trial completion date. this trial is not an applicable trial under food and drug administration amendments act of 2007 (fdaaa).
