A Randomized, Multi-Center Biomarker Trial to Predict Therapeutic Responses of Patients With Rheumatoid Arthritis to a Specific Biologic Mode of Action

• Status: Completed
• Trial end date: 2018-08-01

Summary

The purpose of this study is to find biological response patterns of patients with rheumatoid arthritis to drugs with different biologic modes of action. This study should help to predict therapeutic responses and to find the right therapy for the right patient.

• Phase: Phase 4
• Accepts Healthy Volunteers?: No

Details

• Lead Sponsor: Medical University of Vienna
• Treatments: Abatacept; Diphenhydramine; Infliximab; Promethazine; Rituximab

2. Weigh more than 100 kg

3. Use glucocorticoids >10 mg/day prednisone or equivalent

4. Have previously received other treatments for their rheumatic disease:

1. intra-muscular or intra-articular injection of steroids in the previous month.

2. monoclonal antibodies or antibody fragments, licenced or investigational

3. any investigational drug within 3 months prior to screening or within 5 half-lives of the investigational agent, whichever is longer.

4. Azathioprine or other cytostatic drugs.

5. Have a history of receiving human/murine recombinant products or a known allergy to murine products.

6. Have documentation of seropositivity for human immunodeficiency virus (HIV), or a positive test for hepatitis B surface antigen or hepatitis C ¬antibodies.

7. Have hypergammaglobulinemia

8. Have a history of alcohol or substance abuse within the preceding 6 months.

9. Have or have had a known history of

1. serious infections (such as, but not limited to hepatitis, pneumonia, or pyelonephritis) in the previous 3 months.

2. opportunistic infections (eg, herpes zoster, cytomegalovirus, Pneumocystis carinii, aspergillosis, histoplasmosis, or mycobacteria other than TB) within 12 months prior to screening.

3. a chronic or recurrent infectious disease (eg, chronic renal infection, chronic chest infection, COPD, sinusitis, recurrent urinary tract infection, open, draining or infected skin wound or ulcer etc.).

10. Have undergone any joint replacement surgery.

11. Be men and women of childbearing potential without use of adequate birth control measures (e.g., abstinence, oral contraceptives, intrauterine device, barrier method with spermicide, implantable or injectable contraceptives or surgical sterilization), and willingness to continue this precaution for the duration of the study until 6 months after receiving the last medication.

12. Be considered ineligible according to the tuberculosis (TB) eligibility assessment and screening, or show a positive test for latent Tbc using Quantiferon assay, unless treatment with INH has been installed for at least 2 weeks prior to starting trial drug.

13. Show evidence of malignancy, or lymphoproliferative disease, or any history of malignancy within the previous 5 years, with the exception of basal cell or squamous cell carcinoma of the skin that has been fully excised with no evidence of recurrence.

14. Have current signs or symptoms of severe, progressive or uncontrolled renal, hepatic, hematologic, gastrointestinal, endocrine, pulmonary, cardiac, neurologic, or cerebral disease.

15. Be unable or unwilling to undergo multiple venipunctures because of poor tolerability or lack of easy access.

16. Have presence of a transplanted solid organ (with the exception of a corneal transplant > 3 months prior to screening).
