Trial Outcomes & Findings for PET Imaging With Tc-94m Sestamibi to Assess Resistance to Chemotherapy (NCT NCT00082368)

NCT ID: NCT00082368

Last Updated: 2017-08-17

Results Overview

Sestamibi is a Pgp substrate that may be a surrogate for measuring drug efflux from tumors. Significant increase in the SUV in tumor is +25% over baseline.
