Safety and Efficacy of FolateScan (Technetium Tc 99m EC20) in Subjects With Pituitary Tumors

This study has been completed.

Endocyte Identifier:
First received: September 9, 2012
Last updated: September 17, 2012
Last verified: September 2012
Many types of cancers overexpress a receptor for the vitamin folate (Folate Receptor). This Phase 2 study will utilize a standard imaging radionuclide, technetium-99m, conjugated to a ligand (EC20) designed to bind to the folate receptor. The study is designed as an open-label, baseline-controlled study.

Technetium Tc 99m EC20 Drug: Technetium Tc 99m EC20

Detailed Description:
This is a Phase 2 open-label, single-treatment group, baseline-controlled study designed to verify product safety, gather data on the percentage of subjects with pituitary tumors with increased uptake of FolateScan in tumors and correlate the immunohistochemical staining findings with the FolateScan images, in subjects with pituitary tumors.
