Schedules of Nab-Paclitaxel in Metastatic Breast Cancer

Belgium, Ireland258 participantsStarted 2013-04

Plain-language summary

Longer first line chemotherapy duration has recently been associated with a modest, but significant improvement in overall survival and a clinically meaningful and statistically significant improvement in progression-free survival, in metastatic breast cancer patients. Prolonging chemotherapy until disease progression, however, must be weighed against the detrimental effects of continuous chemotherapy delivery. The SNAP trial seeks to improve the tolerability of prolonged chemotherapy administration strategy by studying alternative treatment schedules, while preserving and possibly improving treatment efficacy in this disease setting. The availability of a new nanoparticle albumin-bound taxane, nab-Paclitaxel (Abraxane®), represents an opportunity to test this hypothesis. Nab-Paclitaxel has been developed in an attempt to reduce the toxicity associated with standard taxane administration (caused by the use of chemical solvents) while increasing antitumor efficacy. The SNAP randomized phase II trial evaluates three schedules of nab-Paclitaxel as prolonged chemotherapy administration strategy. Each of three arms will be compared to a historical reference of seven-month median progression-free survival (PFS) based on the most recent trial with docetaxel as control arm to determine whether any of the three arms are worthy of further investigation.

Inclusion Criteria: * Histologically or cytologically confirmed HER2-negative metastatic (stage IV) breast cancer. * Measurable or non-measurable, but radiologically evaluable, disease according to RECIST 1.1 criteria. * Female aged 18 years or older. * Life expectancy \> 3 months. * Eastern Cooperative Oncology Group (ECOG) performance status 0 or 1. * Either ER-positive or ER-negative disease. Patients with ER-positive disease must be endocrine resistant, defined as having failed at least one prior endocrine therapy for breast cancer, or must be candidates for first-line chemotherapy. * If previously treated with a taxane or anthracycline in the neoadjuvant or adjuvant setting, the period from end of treatment to disease recurrence must have been \> 12 months (\> 365 days). * Radiation therapy, if given and regardless of site, must be completed at least 2 weeks prior to randomization. * Normal hematologic status. * Normal renal function. * Normal liver function. * Normal cardiac function. * Women of childbearing potential: documented negative pregnancy test within 2 weeks prior to randomization, and acceptable birth control during the duration of the trial therapy and for a period of 6 months following the last administration of study drug. * Written Informed Consent (IC) must be signed and dated by the patient and the Investigator prior to randomization. * Completed baseline Quality of Life Form. * The patient has been informed of and agrees to data transfer and handling,…
