Plain English Summary

Background and study aims
Systemic lupus erythematosus (SLE) is a severe, long-term relapsing disease of unknown cause that predominantly affects young women. In this disease, the immune system attacks and injures various tissues in the body, including kidneys (nephritis). Lupus nephritis causes leakage of protein from the kidneys resulting in swelling of the legs and face, can cause kidney failure and can be life threatening. The use of high doses of steroids and other drugs, such as MMF, can control the disease. However, the steroids in particular are toxic with serious short- and long-term side effects that damage patients. There is a need to reduce the use of steroids in patients with lupus. Rituximab has been used in many patients already and appears to be effective and our initial studies suggest it is effective when used with MMF but without oral steroids. We aim to find out if the drug combinations are effective in treating lupus nephritis.

Who can participate?
Adult patients (aged 18-75 years old) and children aged 12-17 years old with lupus nephritis can participate in the study.

What does the study involve?
Patients will be randomly allocated to one of two groups: intervention group and control group. Interventional arm patients receive rituximab and methylprednisolone through a vein and those in the control arm gets methylprednisolone through a vein and oral prednisolone (standard of care treatment). Patients will be asked to take part in the study for a minimum of 2 years, up to 4 years. In that time patients will be followed closely to collect information about their progress. There will be a maximum of 29 research visits - the same as if the patients was not in the study.

What are the possible benefits and risks of participating?
Infusion reactions are seen with rituximab but all patients in this study will receive methylprednisolone through a vein prior to the rituximab infusion and will additionally be given antihistamines and paracetamol. There are no severe side effects or serious infections with the rituximab group. It is important to balance the potential risks of any new therapy with the serious consequences of uncontrolled lupus nephritis and the toxicity of current treatments. Patients will be recruited and followed up in experienced centres familiar with both routine treatment and the use of rituximab. Participants in the intervention group may be at an increased risk for flare compared with patients who take MMF and oral steroids. Renal flare is a risk factor for developing end-stage renal disease. However, our initial data do not suggest a high flare rate and it is possible that exposure to rituximab early in treatment, as proposed in the current study, may reduce later risk of flare.

Where is the study run from?
The study is conducted from the following hospitals across the UK and also from centres in Europe and USA:
Hammersmith Hospital, University of Manchester, University of Leicester, Doncaster & Bassetlaw Hospitals, UCH, New Queen Elizabeth Hospital, Evelina Children's Hospital, Freeman Hospital, UCH - Arthritis Research UK Centre for Adolescent Rheumatology, Alder Hey Children's Hospital, Edinburgh, Worcestershire Royal Hospital, Cambridge University Hospitals NHS Trust, Great Ormond Street Hospital, Nottingham University Hospitals NHS Trust, King's College London, City Hospital, St Mary's Hospital Dunfermline, Dorset County Hospital, Glasgow Renal and Transplant Unit, Birmingham Children's Hospital, Central Manchester University Hospitals NHS Trust, Royal Free Hospital, Victoria Hospital-Fife, Guy's Hospital, Chapel Allerton Hospital, Royal Blackburn Hospital, St Thomas Hospital, St Luke's Hospital, Western Infirmary

When is study starting and how long is it expected to run for?
The study is now open for recruitment. The last participant recruited is planned to be 14 April 2017 and the study close out will commence on 31 July 2019.

Study information

Scientific title

RITUXILUP - An open label randomised multicentre controlled trial of RITUXImab and mycophenolate mofetil (MMF) without oral steroids for the treatment of LUPus nephritis



Study hypothesis

RITUXILUP is a proof of concept open labeled randomized controlled multicentre trial that sets out to address two key questions:
1. What is the role of Rituximab in treating lupus nephritis?
2. Does Rituximab permit removal of oral steroids and does this increase the safety of the treatment?
Based on published data, our pilot data and the huge experience of the detrimental effects of steroids, we plan to test the hypothesis that in steroid-naïve patients with a new flare of lupus nephritis, the addition of Rituximab to mycophenolate mofetil (MMF) but without oral steroids, is at least as effective at inducing a response as the standard of care therapy comprising MMF and oral steroids. By demonstrating non-inferiority of the Rituximab-based, oral steroid-free regimen, this trial would change the fundamental landscape of the treatment of lupus nephritis for the first time in 60 years. Patients who fulfil the eligibility criteria and have provided informed consent will be randomised on a 1:1 basis to either the Rituximab and no oral steroid arm or the standard of care arm.

On 29/09/2014 the following changes were made to the trial record:
1. The overall trial start date was changed from 01/01/2014 to 01/10/2014.
2. The overall trial end date was changed from 30/11/2017 to 01/06/2018.

On 21/05/2015 the following changes were made to the trial record:
1. The overall trial start date was changed from 01/10/2014 to 14/04/2015.
2. The overall trial end date was changed from 01/06/2018 to 31/07/2019.

Lupus nephritis


Participants are randomised to two groups:
1. Treatment group - You will receive the study drug Rituximab and Methylprednisolone by intravenous ('in the vein') therapy. Rituximab can sometimes make you itchy and can give you a fever. To prevent this, we will also give you an anti-allergy medicine, antihistamine, either as a tablet or intravenously and an anti-fever medicine, paracetamol.
2. Control group - You will not be given Rituximab. You will receive methylprednisolone by intravenous therapy and start oral prednisolone. The oral prednisolone is taken as tablets and the dose of oral prednisolone will go down during the trial and may even be stopped as decided by the Research Doctor or Principal Investigator.

We will be recruiting patients like you all over in the UK, Europe and United States of America. You will be asked to take part in the study for at least 2 years and possibly up to 4 years. There will be a maximum of 29 research visits during this time. There is a 2-year follow-up. The number of assessments will not be more than your routine visits.
