Tc 99m Tilmanocept Imaging for Early Prediction of Anti-TNFα Therapy Response in Moderate to Severe Active RA

Phase 3

Terminated

Conditions: Rheumatoid Arthritis

Interventions: Drug: TC99m-tilmanocept

Registration Number: NCT05246280

Lead Sponsor: Navidea Biopharmaceuticals

Brief Summary: This study will confirm the ability of Tc 99m tilmanocept imaging to predict clinical response in individuals with RA who are beginning anti-TNFα therapy.

Detailed Description: This is a prospective, open-label, multicenter study designed to evaluate the early predictive capacity of Tc 99m tilmanocept planar imaging for downstream clinical response(s) in individuals with moderate to severe RA who are candidates for change in anti-TNFα therapy. Temporal (Baseline to 5 week) differences in quantitative imaging will be correlated with longitudinal (Baseline to 12- and 24-week) assessments of clinical RA outcomes to evaluate the clinical utility of Tc 99m tilmanocept for the expedited evaluation of antirheumatic treatment efficacy when compared with longitudinal assessments in clinical practice.

The subject has any severe, acute, or chronic medical conditions and/or psychiatric conditions and/or laboratory abnormalities that would impart, in the judgment of the investigator, excess risk associated with study participation or study drug administration that would deem the subject inappropriate for study participation.
The subject has a history of hypersensitivity reactions to TNF-inhibitors.
The subject has a known allergy to or has had an adverse reaction to dextran exposure.
The subject has received an investigational product within 30 days prior to the Tc 99m tilmanocept administration at the first imaging visit (Day 0).
The subject has received intra-articular corticosteroid injections ≤ 8 weeks prior to the first imaging visit (Day 0).
