Trial Identification

Brief Title: A Study of Ispinesib in Metastatic Breast Cancer

Official Title: A Phase I/II Non-Randomized, Open-Label, Dose-Finding Study of Ispinesib (SB-715992) Followed By a Fixed-Dose Study in Chemotherapy-Naïve Patients With Metastatic Breast Cancer (MBC).

Study ID: NCT00607841

Conditions

Breast Neoplasms

Interventions

Ispinesib

Study Description

Brief Summary: The Phase I portion was a dose-escalation study designed to assess safety and tolerability in patients with metastatic breast cancer. Phase II was intended to measure response rate in patients with metastatic breast cancer but did not enroll because the Phase I portion was halted prior to Maximum Tolerated Dose (MTD) determination.

Detailed Description: Only the Phase I portion of the study was enrolled. The Phase I dose-escalation portion of the trial was designed to determine the Dose Limiting Toxicities (DLT) and MTD of Ispinesib (SB-715992) monotherapy when administered as a one-hour infusion on Days 1 and 15 of a 28-day cycle in female patients with locally advanced or metastatic breast cancer. The Phase II regimen was intended to evaluate the MTD determined in Phase I in chemotherapy-naïve female patients with measurable, locally advanced or metastatic breast cancer. Phase II was intended to assess the overall response rate (ORR) derived from individual patient assessments of complete response (CR), partial response (PR), stable disease (SD), or progressive disease (PD) based on RECIST, as determined by independent review.
