Trial Outcomes & Findings for Neo-Adjuvant Study in Triple Negative Breast Cancer Patients (NCT NCT01097642)

NCT ID: NCT01097642

Last Updated: 2021-09-22

Results Overview

The study's primary objective is to determine the pathologic complete response rate (pCR) (breast and axilla) of Ixabepilone versus Ixabepilone when combined with cetuximab in patients with invasive breast adenocarcinoma T1N1-N3M0 or T2-4 N0-3M0 disease who are triple negative and who are candidates for preoperative chemotherapy. The criteria used: "Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.0) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions; Partial Response (PR), \>=30% decrease in the sum of the longest diameter of target lesions; Overall Response (OR) = CR + PR.", or similar definition that is accurate and appropriate.

Measure
Ixabepilone
Brand name is Ixempra ®; it is an epothilone B analog used in combination with other chemotherapeutics against cancer. Ixabepilone: Ixabepilone will be given at 40mg/m\^2 IV over 180 minutes on day 1 of each of four 21 day cycles.
Ixabepilone Plus Cetuximab
Cetuximab, brand name Erbitux, is an epidermal growth factor receptor (EGFR) inhibitor and monoclonal antibody used with Ixabepilone against cancer. Cetuximab: Cetuximab will be given at 400mg/m\^2 IV over 120 minutes for its initial loading dose on day 1 of the first of four 21 day cycles. It will then be administered on a weekly basis at 250 mg/m\^2 IV over 60 minutes. Ixabepilone: Ixabepilone will be given at 40mg/m\^2 IV over 180 minutes on day 1 of each of four 21 day cycles.

SECONDARY outcome

Timeframe: one year after last treatment dose

The number of participants with adverse events will be measured. Toxicity/safety will be assessed by the National Cancer Institute Common Terminology Criteria for Adverse Events (NCI CTCAE v.3.0). Baseline signs and symptoms will be recorded and followed throughout the trial. Toxicity assessments will be continuous during treatment and the year of follow-up, after which all study drug-related toxicities will be deemed resolved, stabilized, or irreversible. Vital signs will be performed at baseline and will be monitored pre-dose and during study drug administration for Cycles 1 - 4. Chemistry and hematology laboratory tests will be done at baseline and prior to each subsequent chemotherapy cycle.
