Study Endpoints

Primary Endpoints

Concordance of Blue Dye and Lymphoseek
Surgery after injections of Lymphoseek and blue dye

The proportion of lymph nodes detected intraoperatively by blue dye that were also detected by Lymphoseek.

Localization of Tc 99m Tilmanocept by Planar and SPECT/CT Imaging in Subjects With Active RA and Concordance With Swollen/Tender Joints
Swollen/tender joints assessment at baseline and Tc 99m tilmanocept localization at 2-3 hours and 4-6 hours after administration on Day 1

The primary endpoint was to compare the cumulative total of anatomical zones of active RA (which were clinically defined by a swollen/tender classification during the DAS28 joint count assessment performed at baseline) with Tc 99m tilmanocept localization observed at 2-3 hours and at 4-6 hours after administration on Day 1. Tc 99m tilmanocept localization is defined by accumulation of radioactivity at an intensity greater than background, which was qualitatively determined by the central reader's visual assessment of the acquired images .
