研究概览
简要总结
The purpose of this study is to determine the recommended phase 2 dose and overall safety and tolerability of TRC105 when given in combination with capecitabine for the treatment of patients with progressive or recurrent metastatic breast cancer.
详细描述
All patients were required to sign a consent form prior to undertaking any study-related procedures. Prospective patients were screened to determine if they qualified for the study within 28 days of enrollment. Patients who qualified received TRC105 i.v. over 1 to 4 hours on Day 1, Day 4, Day 8 and Day 15 of the initial 21-day cycle and Day 1, Day 8 and Day 15 of every subsequent 21-day cycle in combination with 1000 mg/m2 capecitabine BID for 14 days of each 21-day cycle. Those who tolerated TRC105 without any infusion reactions were eligible for reduced infusion durations. After 3 cycles of treatment, patients who demonstrated a response of complete response (CR), partial response (PR) or stable disease (SD) were eligible for additional treatment for up to six months (9 total cycles). Upon discussion with TRACON, patients judged by the Principal Investigator to be benefiting from treatment were able to continue treatment on this protocol beyond six months.
Toxicities were graded according to the NCI CTCAE Version 4.0. Patients who exited the study for reasons other than drug-related toxicity prior to completion of the first 21-day cycle were replaced. Intra-patient dose escalation was not allowed.
