Rituximab Objective Outcome Measures Trial in SLE (ROOTS)

30 de abril de 2019 actualizado por: University of Leeds

A Feasibility Randomised Placebo-controlled Trial With Objective Outcome Measures to Evaluate the Efficacy of Biosimilar Rituximab in Musculoskeletal and Mucocutaneous Systemic Lupus Erythematosus

This is a feasibility study to test a new trial design for an important drug in Systemic Lupus Erythematosus (SLE or "lupus").

SLE is an autoimmune disease. The immune system attacks the body's own tissues, any part of the body may be affected, but most commonly lupus causes a rash and arthritis, this affects patients' quality of life.

Lupus is usually treated with steroids or drugs that suppress the immune system. Although these help, many patients don't respond well enough and there is also concern for long term side effects. There is a new type of treatment called biologics. These target individual cells or molecules rather than the whole immune system and may be more effective with fewer side-effects. B cells are a part of the immune system that are known to play a role in lupus. There is already a biologic that removes these, called rituximab. In rheumatoid arthritis and vasculitis (similar to lupus), rituximab has been proven to be effective in clinical trials. However, in lupus clinical trials it did not seem to show any benefit. But many doctors and patients found that rituximab is effective, but the trials couldn't show this because of the way the drug's effects were measured. Therefore it is important that we test whether it truly is effective for lupus.

In this 6 month clinical study the investigators will look at lupus patients who have skin disease and arthritis as these are very common and randomise them to receive either rituximab or a placebo. Patients will have a careful clinical examination and undergo different methods to measure the effectiveness of the treatment. There are new versions to rituximab called "biosimilars". In this study biosimilar GP2013 will be used.

If this trial is successful a larger definitive study will be designed based on its results.

  • No contraindication to the use of IV methylprednisolone, biosimilar rituximab, or any other required medications such as antipyretics and antihistamines
  • Willing to use appropriate contraception if at risk of pregnancy
  • Disease activity that is refractory to hydroxychoroquine, or patients unable to take hydroxychoroquine due to contra-indication or prior toxicity

Exclusion Criteria:

  • • Severe "critical" SLE flare defined as: (i) BILAG 2004 A flare in CNS system; (ii) BILAG 2004 A flare in the renal system; or (iii) any other SLE manifestation requiring more immunosuppression than allowed within the protocol in the physician's opinion

    • Pregnancy
    • Breast Feeding
    • Receipt of daily oral glucocorticoids greater than 10mg prednisolone or equivalent at screening or within the previous 5 days, or change in glucocorticoid dose in the previous 5 days.
    • Receipt of intramuscular or intravenous glucocorticoids within the past 4 weeks
    • Receipt of intravenous immunoglobulin, plasma exchange or cyclophosphamide within the last 3 months
    • Rituximab within the past 18 months or other biologic therapies within the past 6 months
    • Active infections, including but not limited to the human immunodeficiency virus, hepatitis B (including prior infection as judged by positive Hepatitis B core antibody) or hepatitis C
