Trial Outcomes & Findings for Phase 2 Study of Gemzar, Taxol & Avastin Combination as 1st Line Treatment for Metastatic Breast Cancer (NCT NCT00403130)

NCT ID: NCT00403130

Last Updated: 2019-02-20

Results Overview

Time-to-Progression (TTP) was assessed as the time from start of treatment to progression, as observed on radiographic scans and assessed per the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria for progressive disease (ie, a 5-mm absolute increase of the sum of the longest diameters of the target lesions in addition to a 20% increase in the sum of the target lesions)

PRIMARY outcome

Timeframe: 2 years

Population: Disease progression was documented for 9 participants.

Time-to-Progression (TTP) was assessed as the time from start of treatment to progression, as observed on radiographic scans and assessed per the Response Evaluation Criteria in Solid Tumors (RECIST) v1.1 criteria for progressive disease (ie, a 5-mm absolute increase of the sum of the longest diameters of the target lesions in addition to a 20% increase in the sum of the target lesions)

Time-to-Progression (TTP)
8.9 months
Standard Deviation 5.9

SECONDARY outcome

Timeframe: 24 weeks

Population: Although 24 participants completed treatment, only 13 were evaluable for treatment effect.

The best overall response was recorded for each participant from randomization until disease progression/recurrence, using any increase from the smallest measurements recorded since randomization as the indicator of Progressive Disease (PD). Overall response was determined on the basis of response at the target and non-target lesions, and the appearance of new lesions, as follows. Target Nontarget New Lesions Overall Response * Complete Complete None Overall Complete Response * Complete Incomplete response/ None Overall Partial Response Stable Disease (SD) * Partial Not PD None Overall Partial Response * SD Not PD None Overall Stable Disease * PD Any Yes/No Overall PD * Any PD Yes/No Overall PD * Any Any Yes Overall PD Overall Response Rate (ORR) was assessed as the sum of the Complete Response (CR) rate and the Partial Response (PR) rate.
