Trial Outcomes & Findings for Evaluation of Metformin, Targeting Cancer Stem Cells for Prevention of Relapse in Gynecologic Patients (NCT NCT01579812)

NCT ID: NCT01579812

Last Updated: 2018-05-25

Results Overview

Determine the percentage of patients alive without recurrence at 18 months. Investigators will also determine recurrence free survival when patients with persistent disease are excluded. Definition of progression or recurrence and survival will be defined as increasing clinical, radiological or histological evidence of disease since study entry or two serum values of CA-125 greater than or equal to two times the upper limits of normal (ULN) performed at least one week apart, regardless of CT scan results. Recurrence-Free Interval will be defined as date from start of chemotherapy to the date of first clinical, biochemical, or radiological evidence of progression or death due to any cause.

PRIMARY outcome

Timeframe: 18 months

Population: 90 patients were enrolled, only 38 completed treatment and were analyzed. Patients found to have persistent disease were censored at the time they were found to have progressive disease. 11 patients had persistent disease.

Determine the percentage of patients alive without recurrence at 18 months. Investigators will also determine recurrence free survival when patients with persistent disease are excluded. Definition of progression or recurrence and survival will be defined as increasing clinical, radiological or histological evidence of disease since study entry or two serum values of CA-125 greater than or equal to two times the upper limits of normal (ULN) performed at least one week apart, regardless of CT scan results. Recurrence-Free Interval will be defined as date from start of chemotherapy to the date of first clinical, biochemical, or radiological evidence of progression or death due to any cause.

Recurrence-Free Survival
58.1 percentage of patients
Interval 38.0 to 73.8
55.6 percentage of patients
Interval 35.2 to 71.8

SECONDARY outcome

Timeframe: Up to 3 Years

Population: 90 patients were enrolled and only 38 patients completed treatment. 25 of the 38 patients had stage IIc/III ovarian cancer. 13 of the 38 patients had stage IV ovarian cancer.

Determine the median overall survival time for all patients who complete treatment as well as for patients presenting with stage IIc/ III and stage IV ovarian cancer.
