Evaluation of Tc 99m Tilmanocept Imaging for the Early Prediction of Anti-TNFα Therapy Response in Patients With Moderate to Severe Active Rheumatoid Arthritis (RA)

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.

Inclusion: The subject has provided written informed consent with HIPAA (Health Information Portability and Accountability Act) authorization before the initiation of any study-related procedures; The subject is at least 18 years of age and was ≥ 18 years of age at the time of RA diagnosis; The subject is a candidate for initiation of, or change to, a new anti-TNFα bDMARD therapy; The subject has RA as determined by the 2010 American College of Rheumatology/European League Against Rheumatism (ACR/EULAR) Classification Criteria (score of ≥ 6/10); The subject has moderate to severe RA as determined by a 28-joint disease activity score (DAS28) of ≥ 3.2 (includes the Erythrocyte Sedimentation Rate [ESR] test and Visual Analog Scale [VAS]); Subjects receiving traditional DMARDs must have been on therapy for ≥ 90 days and at a stable dose for ≥ 30 days prior to the first imaging visit (Day 0); Subjects receiving bDMARD or janus kinase (JAK) inhibitor therapy must have been at a stable dose > 60 days prior to the first imaging visit (Day 0); If the subject is receiving NSAIDS (nonsteroidal anti-inflammatory drug) or oral corticosteroids, the dose has been stable for > 28 days prior to the first imaging visit (Day 0). The corticosteroid dose must be ≤ 10 mg/day of prednisone or an equivalent steroid dose.

Exclusion: The subject is currently receiving radiation therapy or chemotherapy or has received radiation or chemotherapy within the past 5 years; 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); The subject has received any radiopharmaceutical within 7 days or 10 half-lives prior to the administration of Tc 99m tilmanocept at the first imaging visit (Day 0); The subject has an active malignancy or a history of malignancy within the past 5 years; The subject has renal insufficiency as demonstrated by a glomerular filtration rate of < 60 mL/min; 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 heart failure [New York Heart Association (NYHA) Class III-IV], a demyelinating disorder, or a chronic/latent infection [e.g., +Purified Protein Derivative (PPD) test, Human Immunodeficiency Virus (HIV), Hepatitis B]; The subject has hepatic insufficiency as demonstrated by ALT (alanine aminotransferase [SGPT]) or AST (aspartate aminotransferase [SGOT]) greater than 2 times the upper limit of normal; 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 is pregnant or lactating; The subject size or weight is not compatible with imaging per the investigator; The subject has had a finger, hand, and/or wrist amputation or hand or wrist joint arthroplasty.
