Heme Arginate in Transplantation Study

- Interventions
- Drug: 0.9% Sodium-chloride
- Registration Number
- NCT03646344
- Lead Sponsor
- University of Edinburgh
- Brief Summary
Organ shortage for transplant has necessitated use of kidneys from older donors, increasing the chance that the kidney will not work immediately or for as long as expected. The investigators gave the drug heme arginate (HA) to 20 kidney transplant patients in the first 24 hours after transplant, and showed that it may reduce kidney injury and is safe. The investigators plan to conduct a large study recruiting 600 patients to determine whether HA treatment increases the number of kidney transplants that work immediately. If successful, HA may be introduced into clinical practice at the end of this study.
Patients will be invited to take part in the study once listed for a kidney transplant. Further discussions will be had with them when admitted for transplant, and they will be offered the opportunity to participate. Consent will not be taken until the patient is admitted for transplantation. Following consent, participants will be randomised to receive either 2 doses of the study drug, HA, or a salt water solution, one at the time of transplant, and one approximately 24 hours later. Otherwise, treatment will be the same as any other patient undergoing a kidney transplant. Information about recovery from surgery, and specifically about kidney function, will be collected, but will not require additional blood tests. The study period ends after the first 7 days post-transplant, although longer term data will be collected from routine follow up appointments. Participants will be asked to complete a simple quality of life questionnaire 3 times: just before transplant, at approximately one week and three months after transplant.

Group Intervention Description Active Group Heme Arginate 25 MG/ML Will receive Heme Arginate (IMP) at a dose of 3mg/kg over 30mins. Participants will receive infusions of the IMP at 2 time-points, the first prior to surgery (transplantation), and the second 20-28 hours later. At each infusion, the IMP will be followed by a 100ml infusion of 0.9% Sodium Chloride over 15mins. Placebo Group 0.9% Sodium-chloride Will receive a 100ml infusion of 0.9% Sodium Chloride (placebo) over 30mins. Participants will receive infusions at 2 time-points, the first prior to surgery, and the second 20-28 hours later. At each infusion, the placebo will be followed by a further 100ml infusion of 0.9% Sodium Chloride over 15mins.
- Primary Outcome Measures
Name Time Method Delayed Graft Function 1 week post transplant The incidence of delayed graft function, defined as failure of a spontaneous fall in creatinine of \>10% for each 3 consecutive day period in the first week following transplantation, with comparison between the two randomised groups.
- Secondary Outcome Measures
Name Time Method Requirement for dialysis 1 week post transplant The number of participants requiring dialysis within the first week post-transplant
Time to functioning graft 1 week The number of days to functioning graft, defined as the spontaneous fall in creatinine of greater than, or equal to 10% over a period of 3 consecutive days in the first 7 days post transplant
Length of hospital stay 3 months The number of days spent in hospital, along with level of care (ward/HDU/ITU), for the index admission (transplantation admission)
Creatinine levels 3 months Serum creatinine levels at 1 and 3 months post-transplant across both randomised groups
Acute rejection 3 months The number of participants with biopsy-proven acute rejection within the first 3 months post-transplant
SF36 Quality of Life Up to 3 months post transplant A comparison of differences between groups in patient reported quality of life using the SF36
Cost per QALY gained Up to 3 months post transplant Using data derived from the SF36 to weight survival for quality of life, Quality Adjusted Life Year (QALY) will be assessed
