Dosing Regimen of Eculizumab Added to Conventional Treatment in Positive Crossmatch Deceased Donor Kidney Transplant
This trial is active, not recruiting.
|Phase||phase 1/phase 2|
|Start date||March 2010|
|End date||December 2016|
|Trial size||40 participants|
|Trial identifier||NCT01106027, 09-005627DD|
The purpose of this study is to test whether a dosing regimen of eculizumab in addition to standard posttransplant care in positive crossmatch deceased donor kidney transplant recipients will reduce the incidence of acute humoral rejection (AHR).
Patients included in this study will be those who have demonstrable anti-human leukocyte antigen (HLA) antibody specific for their deceased donor. It is our hypothesis that blockade of terminal complement activation with eculizumab at the time of transplant in combination with our current protocols will reduce the incidence of AHR in recipients of deceased donor kidney transplants who have anti-donor HLA antibody
|Endpoint classification||safety/efficacy study|
|Intervention model||single group assignment|
Number of subjects with acute humoral rejection (AHR) up to one year post transplant.
time frame: 1 year posttransplant
Male or female participants at least 18 years old.
Inclusion Criteria: - 18 years of age - Has end stage renal disease (ESRD) and is to receive a kidney transplant from a DD to whom he/she has a positive T or B cell crossmatch >200 at the time of transplant and DSA demonstrated by solid phase assays. - Willing to comply with the protocol - Females of child-bearing potential must have a negative pregnancy test (serum β-HCG) and sexually active females must agree to use a reliable and medically approved method of contraception - Willing and able to give written informed consent - Vaccinated against Neisseria meningitides (quadrivalent vaccine), Pneumococcus and H. influenzae at least two weeks prior to beginning desensitization Exclusion Criteria: - Unstable cardiovascular condition - Previous splenectomy - Active bacterial or other infection which is clinically significant in the opinion of the investigator - Known or suspected hereditary complement deficiency - Participation in any other investigational drug study or was exposed to an investigational drug or device within 30 days of randomization - Pregnant, breast-feeding, or intending to conceive during the course of the study, including a one month follow-up period after drug discontinuation - Known hypersensitivity to the treatment drug or any of its excipients - History of illicit drug use or alcohol abuse within the previous year - History of meningococcal disease - Medical condition that, in the opinion of the investigator, might interfere with the patient's participation in the study, pose an added risk for the patient, or confound the assessment of the patient (e.g. severe cardiovascular or pulmonary disease)
|Official title||A Single Center, Open-label Study to Determine the Safety and Efficacy of a Dosing Regimen of Eculizumab Added to Conventional Treatment in the Prevention of Acute Humoral Rejection (AHR) in Positive Crossmatch Deceased Donor Kidney Transplantation (+XMatch DDKTx)|
|Principal investigator||Mark Stegall, MD|
|Description||A strongly positive crossmatch has long been considered an absolute contraindication to kidney transplantation and most patients with anti-HLA antibody never were able to receive a kidney transplant. Over the past decade, significant progress has been made in overcoming early antibody-mediated renal allograft injury. Despite our best efforts, transplantation in these patients is still complicated by a high rate of acute humoral rejection. While we have successfully transplanted more than 250 patients with DSA using living donors, applying these protocols to recipients of deceased donors has been problematic. This primarily is due to the fact that in contrast to living donation, the timing of a deceased donor kidney transplant cannot be planned. This leads to inadequate time to perform the multiple pretransplant plasmapheresis treatments needed to achieve a safe level of DSA at transplant. Thus, there is a major unmet need to develop therapy that will allow for the successful transplantation of deceased donor kidneys in recipients who have DSA.|
