Trial Outcomes & Findings for Window of Opportunity Trial of Dasatinib in Operable Triple Negative Breast Cancers With nEGFR (NCT NCT02720185)
NCT ID: NCT02720185
Last Updated: 2022-06-03
Results Overview
An increase of at least 25% from baseline to post-dasatinib treatment will be considered significant. VECTRA is an automated pathology imaging system used to detect biomarkers in samples.

SECONDARY outcome
Timeframe: Up to 4 weeksSafety and tolerability of dasatinib in participants with operable Triple negative breast cancer (TNBC) will be based on NCI Adverse Events (AE) Version 4.0 and will be assessed by frequency tables. AEs were collected on day 1 of treatment and a minimum of 14 days after the last dose. AEs reported here were ranked as either possibly related, probably related, or definitely related to the study intervention. All AEs (including not related and unlikely related) are summarized in the AE section.
