Cu64-DOTA-trastuzumab PET and Markers Predicting Response to Neoadjuvant Trastuzumab + Pertuzum in HER2+ Breast Cancer
Use of 64Cu-DOTA-Trastuzumab PET Imaging and Molecular Markers for Prediction of Response to Trastuzumab and Pertuzum-Based Neoadjuvant Therapy
Study Overview
Status
Conditions
Detailed Description
PRIMARY OBJECTIVES:
I. To evaluate the standardized uptake value maximum (SUVmax) in patients with previously untreated HER2+ breast cancer.
SECONDARY OBJECTIVES:
I. To evaluate if the uptake of copper 64 Cu-64-DOTA-trastuzumab, a proposed indicator of responsiveness to HER2-directed therapy, correlates with serpin peptidase inhibitor alpha-1 antiproteinase, antitrypsin, member 1 gene (SERPINA1) expression, which has been shown to be associated with estrogen receptor positive (ER+)/ HER2+ patient survival, both in the HER2+/ER+ patients and in all patients.
II. To compare uptake of copper Cu 64-DOTA-trastuzumab in the patients with complete pathologic response (pCR) versus (vs) non-pCR patients.
OUTLINE:
Patients receive trastuzumab intravenously (IV) over 15 minutes immediately before receiving copper Cu 64-DOTA-trastuzumab IV on day 0. Patients undergo PET scans at 18-24 and 42-48 hours, on day 1 and 2. Within 4 days after completion of PET scans, patients then receive trastuzumab IV over 30-90 minutes weekly or every 3 weeks and pertuzumab IV over 30-60 minutes. Treatment repeats every 21 days for 6 cycles in the absence of disease progression or unacceptable toxicity. Patients undergo surgery after 6 cycles of trastuzumab and pertuzumab.
After completion of study treatment, patients are followed up for 1 year.

Experimental: Treatment (trastuzumab, copper Cu 64-DOTA-trastuzumab PET)
Patients receive trastuzumab IV over 15 minutes immediately before receiving copper Cu 64-DOTA-trastuzumab IV on day 0. Patients undergo PET scans at 18-24 and 42-48 hours, on day 1 and day 2. Within 4 days after completion of PET scans, patients receive trastuzumab IV over 30-90 minutes weekly or every 3 weeks and pertuzumab IV over 30-60 minutes.
Treatment repeats every 21 days for 6 cycles in the absence of disease progression or unacceptable toxicity.
Patients undergo surgery after 6 cycles of trastuzumab and pertuzumab.

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Response to Neoadjuvant Chemotherapy Determined at Surgery (Lumpectomy or Mastectomy).
Time Frame: Up to 1 year
|
The response assessment is performed at the time of definitive surgery.
Patients' disease will be staged in the conventional manner according to the AJCC.
The primary endpoint is complete pathologic response defined as no evidence of residual invasive cancer in either the breast or regional lymph nodes.
|
Up to 1 year

Other Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
SUV Measurement by 64Cu-DOTA Trastuzumab PET
Time Frame: Baseline
|
First Scan SUV Maximum, measurement by 64Cu-DOTA trastuzumab PET SUV is "Standard Uptake Value".
SUV = tumor activity concentration x patient body weight/injected activity decay-corrected to time of scan.
