Trial Outcomes & Findings for Vaccine and Chemotherapy for Previously Untreated Metastatic Breast Cancer (NCT NCT00048893)

NCT ID: NCT00048893

Last Updated: 2012-04-13

Results Overview

Complete response (CR) is the complete disappearance of all measurable and evaluable disease. Partial response (PR) is a decrease of greater than or equal to 50% in the sum of the products of the longest perpendicular dimensions of all measurable target lesions. Stable disease (SD) is any decrease of less than 50% or increase less than 25% in the sum of the longest perpendicular dimensions of measurable disease. Progressive disease (PD) is a greater than 25% increase in the sum of the longest perpendicular dimensions of any measurable disease.

PRIMARY outcome

Timeframe: time to progression, response rate: evaluation every 3 months for 3 years, then every 6 months for one year (fourth year), then yearly thereafter until taken off study

Population: The study was closed to accrual due to very poor enrollment. No meaningful data analysis was possible on the small number of accrued subjects, so none was done.

Complete response (CR) is the complete disappearance of all measurable and evaluable disease. Partial response (PR) is a decrease of greater than or equal to 50% in the sum of the products of the longest perpendicular dimensions of all measurable target lesions. Stable disease (SD) is any decrease of less than 50% or increase less than 25% in the sum of the longest perpendicular dimensions of measurable disease. Progressive disease (PD) is a greater than 25% increase in the sum of the longest perpendicular dimensions of any measurable disease.

SECONDARY outcome

Timeframe: time to progression, response rate: evaluation every 3 months for 3 years, then every 6 months for one year (fourth year), then yearly thereafter until taken off study

Population: The study was closed to accrual due to very poor enrollment. No meaningful data analysis was possible on the small number of accrued subjects, so none was done.

The log change in CEA-specific T cell precursor frequency will be calculated between values obtained at baseline and 5 months post immune depletion. A change equal to 1.0 standard deviation (SD) of the log change is significant.

SECONDARY outcome

Timeframe: Baseline and 5 months post immune depletion

Population: The study was closed to accrual due to very poor enrollment. No meaningful data analysis was possible on the small number of accrued subjects, so none was done.

Response is evaluated by CD4 response to CEA soluble protein. The log change in precursor frequencies will be calculated between values obtained at baseline and five months post immune depletion. By flow cytometry of peripheral blood lymphocyte frequency of potential killer cells directed to the CEA protein.

SECONDARY outcome

Timeframe: 2 years

Population: The study was closed to accrual due to very poor enrollment. No meaningful data analysis was possible on the small number of accrued subjects, so none was done.

It is expected that delayed administration of a vaccine will result in enhancement of immune response to the vaccine in those patients with later recovery of thymic function as evidenced by change in lymphocyte subsets in the blood.

SECONDARY outcome

Timeframe: After the immune depletion cycle

Population: The study was closed to accrual due to very poor enrollment. No meaningful data analysis was possible on the small number of accrued subjects, so none was done.

The time period a participant remains free from progressive disease. Progressive disease (PD) is defined as a greater than 25% increase in the sum of the longest perpendicular dimensions of any measurable disease or the appearance of new disease or an increase in evaluable disease.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: 6 weeks, than 6, 12, 18, 24, 30, 36 (3y), 42, 48 (4y), 60 and 72 months after completion of immune chemotherapy

Population: The study was closed to accrual due to very poor enrollment. No meaningful data analysis was possible on the small number of accrued subjects, so none was done.

Patients showing disease progression or recurrence at any point after the start of the early immunizations series may continue on study in accordance to the off study criteria and will be receiving monthly rF immunizations for a total of 12 months or until further disease progression meets the off study criteria. Immune response as evidenced by change in lymphocyte subsets in the blood.

Outcome measures

Outcome data not reported

SECONDARY outcome

Timeframe: At the beginning of each cycle of chemotherapy (every 4 weeks)

Population: The study was closed to accrual due to very poor enrollment. No meaningful data analysis was possible on the small number of accrued subjects, so none was done.

Defined as measurable disease (any solid lesion that can be measured accurately in at least one dimension), evaluable disease (disease not readily measurable but can be clinically assessed), complete response (complete disappearance of all measurable and evaluable disease), partial response (decrease of greater than or equal to 50%), stable disease (any decrease of less than 50% or increase less than 25% in the sum of the longest perpendicular dimensions), or progressive disease (greater than 25% increase in the sum of the longest perpendicular dimensions of any measurable disease).
