Plain English Summary

Background and study aims
Kidney transplantation is the best treatment for end stage kidney disease. Immunosuppression (reducing the strength of the body's immune system) prevents rejection and prolongs the life of a transplant. However, long-term graft loss remains a problem with an incidence of up to 20%. This is mainly due to immune system cells called B cells and the side effects of immunosuppression. Rituximab is a drug that targets B cells, reducing their numbers, and there is evidence that it reduces rejection. The aim of the study is to determine if rituximab in combination with reduced immunosuppression can be used in kidney transplants to reduce the side effects of immunosuppression.

Who can participate?
Patients aged over 18 receiving their first living donor kidney transplant, or their second if the first was not lost from acute rejection.

What does the study involve?
Participants will be randomly allocated to either receive rituximab or to not receive rituximab 2 - 4 weeks before receiving their kidney transplant.

What are the possible benefits and risks of participating?
The potential benefits are significant. If rituximab is effective, patients could be safely managed with a reduced immunosuppressive treatment, which would lead to better graft function, lower rates of post-transplant diabetes, heart complications and infections, and potentially less rejection. This could result in improved long-term graft and patient survival: this would profoundly affect the approach to immunosuppression in kidney transplantation. There are two potential risks for participants: side effects due to rituximab administration, and the risks of rejection related to a reduced immunosuppressive treatment. These will be closely monitored during the study.

Where is the study run from?
Guy’s Hospital, Derriford Hospital, Glasgow Renal and Transplant Unit, Queen Elizabeth Hospital Birmingham, Sheffield Kidney Institute and Manchester Renal Transplant Unit (UK).

When is the study starting and how long is it expected to run for?
From November 2010 to November 2018.

Who is funding the study?
Astellas Pharma and Guy's Hospital Transplant Surgical Research Fund (UK).

Study information

Scientific title

A phase IV open label randomised controlled trial of rituximab in induction therapy for living donor renal transplantation

Acronym

ReMIND

Study hypothesis

Can the use of a single dose of rituximab at induction allow a maintenance regimen of low dose tacrolimus and mycophenylate alone?

As of 22/02/2010 this record was updated to show protocol amendments after ethics approval. All changes can be found under the relevant field with the above update date. At this time, the overall trial start and end dates were amended; the initial overall trial dates were as follows:
Initial overall trial start date: 01/01/2010
Initial overall trial end date: 01/01/2012
Also, please note that the phase of this study has been changed from a phase II study to a phase IV study.

As of 10/12/2010 the overall trial start and end dates were again extended; the previous start and end dates were 01/03/2010 and 01/03/2012, respectively. Follow up is planned to be complete by 16/11/2013. Astellas Pharma was also added as a funder.

On 15/01/2010 Guy's Hospital Transplant Surgical Research Fund (UK) was added as a funder.

Condition

Live donor renal transplantation

Intervention

Pre-medication with paracetamol 1 g orally (PO), hydrocortisone 100 mg intravenously (IV) and chlorphenamine 10 mg IV is provided 30 minutes before start of rituximab infusion. A single dose of rituximab 375 mg/m^2 administered via a dedicated IV line is given 2 - 4 weeks prior to transplantation. The dose should be rounded to the nearest 100 mg unless the difference comprises more than 5% of calculated dose, in which case the dose should be rounded up to the nearest 10 mg.

Patients then receive the medications as below:
1. Basiliximab (Simulect®): 20 mg IV 1 hour prior to induction of anaesthesia, and a further 20 mg IV dose on day 4 post-transplant
2. Tacrolimus: dose calculated to give levels of 3 - 7 ng/ml
3. Mycophenylate mofetil: 2 g/day in divided doses
4. Prednisolone: all patients will be given 1 g methylprednisolone at induction of anaesthesia. Patients receiving rituximab will be given 100 mg hydrocortisone twice daily (bd) on day 1 after transplantation, then prednisolone at 0.3 mg/kg on day 2, 0.25 mg/kg on day 3, 0.2 mg/kg on day 4 and 0.16 mg/kg on day 5. On day 6 they will receive 5 mg prednisolone, and on day 7 none. For patients not receiving rituximab, our current protocol will be followed. Prednisolone will continue at 0.3 mg/kg for the first month after transplantation, 0.25 mg/kg for months 2 and 3, and 0.16 mg/kg for months 4 to 6. Subsequent steroid maintenance or withdrawal will be at the discretion of the patient's clinician.
