Outcomes

Primary Outcome Measures

Incidence of Adverse Drug Reaction

Number of participants that experienced pharmacologic activity or ADR in each dose group.

Secondary Outcome Measures

Per Subject Localization Rate of Tc 99m Tilmanocept by SPECT Imaging

Tc 99m Tilmanocept localization is defined as the visually (i.e., qualitatively) determined binary categorization of Tc 99m tilmanocept activity in a given DAS28 joint. The purpose of the visual assessments is to obtain dichotomized classifications of tracer uptake (herein referenced as 'localization') on planar images. Per subject localization rate is the number of subjects with at least one localized DAS28 joint per number of subjects in the analysis population.

Tc 99m Tilmanocept Joint Localization Rate in Rheumatoid Arthritis Identified Joints

Per joint (clinically RA-identified) joint localization rate of Tc 99m tilmanocept is defined as the number of localized joints per number of joints from subjects in the analysis population Groups 1-9 using SPECT imaging.

Concordance

Concordance is defined as the relationship or the presence of Tc99m localization in anatomical areas of active RA defined by clinical symptomology (defined as joint swelling (SJC) and/or tenderness (TJC) during the screening DAS28 evaluation).

Localization Intensity

Localization intensity is defined as the presence of Tc99m in each DAS28 joint and is output in tilmanocept uptake value (TUV) units, as computed using the following equation: 〖TUV〗=ROI/BRAIN×100 where ROI = decay-corrected avg voxel intensity of the joint ROI and BRAIN =decay-corrected avg voxel intensity of the brain RR

Per Subject Localization Rate of Tc 99m Tilmanocept in Areas Other Than RA

Per subject localization rate of Tc 99m tilmanocept in areas other than RA is defined as the number of subjects with at least one localized DAS28 joint per number of subjects in the analysis population.

Maximum Observed Concentration (Cmax)

Maximum observed concentration (Cmax) will be calculated, whenever possible, using Tc 99m tilmanocept total radioactivity in whole blood and urine.

Time to Cmax (Tmax)

Time to Cmax (tmax) will be calculated, whenever possible, using Tc 99m tilmanocept total radioactivity in whole blood and urine.

Area Under the Concentration-time Curve (AUC) From Hour 0 to the Last Measureable Concentration (AUC0-t)

Area under the concentration-time curve (AUC) from Hour 0 to the last measureable concentration (18 to 20 hours) (AUC0-t) will be calculated, whenever possible, using Tc 99m tilmanocept total radioactivity in whole blood and urine.

AUC Extrapolated to Infinity

AUC extrapolated to infinity will be calculated, whenever possible, using Tc 99m tilmanocept total radioactivity in whole blood and urine.

Apparent Terminal Elimination Rate Constant (Z)

Apparent terminal elimination rate constant (Z) will be calculated, whenever possible, using Tc 99m tilmanocept total radioactivity in whole blood and urine.

Apparent Terminal Elimination Half-life (t1/2)

Apparent terminal elimination half-life (t1/2) will be calculated, whenever possible, using Tc 99m tilmanocept total radioactivity in whole blood and urine.

Radiation Dosimetry of Tc 99m Tilmanocept

Mean total radiation dose per organ (mSv/MBq) in HC females, HC males, females with active RA, and males with active RA. Results were obtained at the subject level from Hybrid Dosimetry™ Version 2.8.3 and OLINDA/EXM® Version 2.1RC93 in accordance with NAV3-21 Protocol Amendment 6. The Hybrid Dosimetry™ function provides an efficient way to generate kinetic data for selected organs via regions of interest (ROI) drawing. From this data, residence times are calculated and transferred to OLINDA/EXM®, which generates absorbed dose tables using the MIRD methodology.

Brief Summary

Prospective, open-label, multicenter, dose escalation, safety with pharmacokinetics (PK) and dosimetry study of injected Tc 99m tilmanocept in the detection of and assessment of localization to skeletal joints in subjects with and without active RA by SPECT imaging.

Detailed Description

A Manocept Platform prospective, open-label, multicenter, dose escalation, safety with PK and dosimetry study of injected Tc 99m tilmanocept in the detection of and assessment of localization to skeletal joints in subjects with and without active RA by SPECT imaging. All subjects will receive IV administration at one of 3 mass doses: 50 µg, 200 µg, or 400 µg. Within each mass dose group, subjects will receive Tc 99m tilmanocept labeled with one of 3 radiolabel doses: 1 mCi, 5 mCi, or 10 mCi. All subjects will have a whole body planar SPECT scan. Subjects enrolled in Groups 1-9 will receive a whole body and planar hands scan followed by SPECT/CT scans on areas of interest post injection at 60 minutes ± 15 minutes and 180 minutes ± 15 minutes. Subjects enrolled in Groups 10-11 will receive a whole body planar SPECT scan performed at 4 specified time points post injection: 15 ± 5 minutes, 60 ± 15 minutes, 180 ± 15 minutes and 18-20 hours. Planar hand scans will be collected at 60 ± 15 minutes and 180 ± 15 minutes post-injection. PK blood sampling will be performed before injection (within 15 minutes), immediately following injection (within 5 minutes) and at each scanning timepoint. Dosimetry tests will be performed at each scanning timepoint. PK of urine will be assessed through counts of the bladder wall obtained from cumulative quantitative planar imaging from radiation dosimetry.
