A Study of LY573636-sodium in Patients With Metastatic Breast Cancer

Phase 2
Completed
Conditions
Breast Cancer
Interventions
Drug: LY573636-sodium
Registration Number
NCT00992225
Lead Sponsor
Eli Lilly and Company
Brief Summary

The primary purpose of this study is to determine the objective response rate (complete and partial response) for patients who receive LY573636-sodium for metastatic breast cancer.

Detailed Description

Patient will receive a 2-hour intravenous infusion of study drug (LY573636-sodium) once every 28 days. Radiologic imaging scans will be performed before the first dose of study drug and then after every other treatment. Patients will be assessed for clinical progression at every visit and for response approximately every 56 days (every other cycle).

Primary Outcome Measures
NameTimeMethod
Percentage of Participants With an Objective Overall ResponseBaseline to measured progressive disease or death from any cause up to 12 months

Objective overall response is complete response (CR) + partial response (PR), as classified by the investigators according to the Response Evaluation Criteria In Solid Tumors (RECIST) guidelines. CR is disappearance of all target and non-target lesions; PR is ≥30% decrease in sum of longest diameter of target lesions. It is calculated as a total number of participants with CR or PR divided by the total number of participants treated multiplied by 100.

Secondary Outcome Measures
NameTimeMethod
Percentage of Participants Experiencing Clinical Benefit [(CR) + (PR) + Stable Disease (SD)]Baseline to measured progressive disease or death from any cause up to 12 months

Clinical Benefit Rate = \[(CR) + (PR) + Stable Disease (SD)\] of at least 4 cycles/N as classified by the investigator according to the RECIST guidelines, where N = total number of participants with at least one dose of study drug. CR is disappearance of all target and non-target lesions; PR is ≥30% decrease in sum of longest diameter of target lesions. SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for progressive disease.

Duration of Stable DiseaseTime from documented Stable Disease (SD) to first date of progressive disease or death from any cause up to 12 months

Duration of stable disease (SD) is defined from date of documented SD to first date of progressive disease (PD) or death from any cause (assessed every other cycle during study therapy, or every 2 months during post-therapy). SD is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD. PR is ≥30% decrease in sum of longest diameter of target lesions. PD is ≥20% increase in sum of longest diameter of target lesions and/or a new lesion.

The Percentage of Participants With Exposures in the Target RangeAfter drug infusion in cycles 1 and 2 (5 samples drawn over each 28 day cycle)

Exposure is the amount of drug the body sees in a period of time. Target range is an exposure thought to offer the optimal balance of safety and efficacy based on prior research.

Duration of Overall ResponseTime of response to progressive disease or death up to 12 months

The duration of a complete response (CR) or partial response (PR) was defined as the time from first objective status assessment of CR or PR to the first time of progression or death as a result of any cause. CR or PR is classified by the investigators according to RECIST guidelines. CR is disappearance of all target and non-target lesions; PR is ≥30% decrease in sum of longest diameter of target lesions.

Progression-free SurvivalBaseline to measured progressive disease or death from any cause up to 12 months

Defined as the time from date of first dose to the first observation of progression of disease (PD) or death due to any cause. PD was determined using RECIST criteria. PD is ≥20% increase in sum of longest diameter of target lesions and/or a new lesion.

Maximum Concentration (Cmax)After drug infusion in cycles 1 and 2 (5 samples drawn over each 28 day cycle)]
