ClinConnect Summary

The TRIBECA study is a clinical trial that aims to evaluate the effectiveness and safety of a medication called belimumab for treating a condition known as non-infectious active cryoglobulinemia vasculitis (CV). This condition is a type of inflammation that affects small blood vessels and can cause symptoms in various parts of the body, such as the skin, joints, and organs. The trial will compare the effects of belimumab to a placebo (a substance with no therapeutic effect) in patients who have recently received another treatment called rituximab. The goal is to see if belimumab can help reduce symptoms and prevent relapses of CV, which can happen in a significant number of patients after initial treatment.

To participate in this study, individuals must be at least 18 years old and have active cryoglobulinemia vasculitis. They should have received rituximab treatment within the past six weeks. The trial is open to all genders, and participants will need to provide consent and follow specific guidelines, including using effective birth control if they are capable of becoming pregnant. Those who join the study can expect to receive either belimumab or a placebo for a set period, and their health will be monitored closely throughout the trial to assess the medication's effects and safety.

• • 2. Written inform consent
• • 3. Active mixed cryoglobulinemia vasculitis, at initiation of rituximab, define by a. a clinically active vasculitis with skin, joint, renal, peripheral nerve, central neurological, digestive, pulmonary and/or cardiac involvement , b. history of positive cryoglobulinemia and/or positive Rheumatoid factor associated with low C4 complement level , and/or a monoclonal component (IgM Kappa) and/or a histologal proof of vasculitis in the affected organs
• • 4. Affiliated to National French social security system
• • 5. Having received Rituximab as induction therapy within 6 weeks (1 to 4 infusions, dose at the discretion of the investigator)
• • 6. Female subjects of childbearing potential must have a negative serum or urinary pregnancy test at inclusion visit, and confirmed monthly while in study, out to at least 92 days (5 half lives) post last dose.
• 7. For subjects with reproductive potential (male or female), a willingness to use contraceptive measures adequate to prevent the subject or the subject's partner from becoming pregnant during the study from 2 weeks prior to administration of the 1st dose of study agent until 92 days after the last dose of study agent. Therefore the subjects agree to 1 of the following:
• • 1. Complete abstinence from intercourse from 2 weeks prior to administration of the 1st dose of study agent until 92 days after the last dose of study agent (Sexual inactivity by abstinence must be consistent with the preferred and usual lifestyle of the subject. Periodic abstinence (e.g. calendar, ovulation, symptothermal, post-ovulation methods) and withdrawal are not acceptable methods of contraception) OR
• • 2. Consistent and correct use of 1 of the following acceptable methods of birth control for 1 month prior to the start of the study agent, during the study, and 92 days after the last dose of study agent o Oral contraceptive, either combined or progestogen alone o Injectable progestogen o Implants of levonorgestrel or etonogestrel o Estrogenic vaginal ring o Percutaneous contraceptive patches o Intrauterine device (IUD) or intrauterine system (IUS) with \<1% failure rate as stated in the product label
• • o Male partner sterilization (vasectomy with documentation of azoospermia) prior to the female subject's entry into the study, and this male is the sole partner for that subject. For this definition, "documented" refers to the outcome of the investigator's/designee's medical examination of the subject or review of the subject's medical history for study eligibility, as obtained via a verbal interview with the subject or from the subject's medical records
