Multicenter randomized double-blind study comparing the efficacy and safety of rituximab in combination with corticosteroids to corticosteroids plus placebo in the treatment of non-infectious active mixed cryoglobulinemia vasculitis.
Cryoglobulinemia are responsible for systemic vasculitis, and the most frequently targeted organs are the skin, joints, kidneys and peripheral nervous system. Cryoglobulinemia vasculitis are associated with significant morbidity and mortality, and require therapeutic intervention. Management of non-infectious mixed cryoglobulinemia vasculitis is based on corticosteroids, plasma exchange, and/or immunosuppressants. These treatments are associated with frequent side effects. To date, no study has evaluated the efficacy and safety of these different therapeutic options, explaining the lack of recommendations.
Rituximab, a monoclonal antibody directed against CD20, has emerged as a novel therapeutic option in B-cell related disorders. Data from the French AutoImmunity and Rituximab (AIR) registry recently reported the positive effect of rituximab in non-infectious mixed cryoglobulinemia vasculitis. More recently, the multidisciplinary national French CryoVas survey also suggested a significant superiority of the combination corticosteroid plus rituximab compared to the corticosteroids alone in terms of complete clinical and immunological responses and corticosteroid sparing. However, no randomized controlled data addressing this issue has been published to date.
31 studies on the registry are indexed under Systemic Vasculitis; 7 are open to participants now.
This study's enrollment of 14 is below the median of 70 across 19 interventional studies indexed under Systemic Vasculitis.

Counted across the registry records on this site, refreshed daily.
Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.
Exclusion Criteria:
History of cancer during the last 3 years before inclusion, including solid tumors, hematological (except lymphoproliferative disorder associated with the mixed cryoglobulinemia vasculitis), and carcinoma in situ (except basal cell and squamous cell carcinoma of the skin that have been treated or excized and cured)"
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.
Read whether the line is about a condition or about medicines, and which medicines and doses it means.
Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.
Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.
Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
The other ingredients in a medicine besides the active drug, such as fillers, colours or preservatives.
A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.
Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.
Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.
