Outcomes

Primary Outcome Measures

Overall Response Rate (ORR)

ORR is defined as the proportion of patients with CR, nCR or partial response (PR) based on modified EBMT criteria per investigator assessment

Secondary Outcome Measures

Progression Free Survival (PFS)

PFS, defined as time from first dose of study treatment to progression or death due to any cause, as assessed by investigator

Overall survival (OS)

OS, defined as time from first dose of study treatment to death

Safety of combination therapy assessed using the National Cancer institute-Common Toxicology Criteria (NCI-CTC) grade scale for AEs and Lab assessments

Safety of combination therapy as assessed by toxicity, which will be assessed using the National Cancer Institute-Common Toxicology Criteria (NCI-CTC) grading scale for Adverse Events and for laboratory assessments (v4.03) that include biochemistry, hematology, urinalysis; special safety assessments that include LVEF, Thyroid function Creatinine clearance and ECGs (electrocardiograms).

5. Study Description

Brief Summary

The purpose of this study is to evaluate the efficacy and safety of paclitaxel in combination with cyclophosphamide and dexamethasone in chinese patients with relapsed/refractory multiple myeloma.

Detailed Description

Treatment for relapsed/refractory multiple myeloma (MM)remains a crucial challenge.The investigators have previously shown that the combination of paclitaxel and cyclophosphamide acts synergistically to induce apoptosis of myeloma cells in vitro. Based on these preclinical studies, the investigators initiated a phase II clinical trial of paclitaxel 175 mg/m(2) IV over 3 h d1 combined with cyclophosphamide 200 mg/m(2) IV over 30-60 min d1,3,5 and dexamethasone 20mg IV over 30-60 min d1-4 in patients with relapsed or refractory MM. This regimen was administered every four weeks for a total of six cycles
