Survival and Dialysis Independency in Highly Sensitized Patients After Desensitization With Imlifidase and Tx of Kidneys (ConfIdeSLTFU)
A Prospective, Long-term Confirmatory Follow up Trial in Highly Sensitized Patients Treated With Imlifidase or Standard of Care in the ConfIdeS (20-HMedIdeS-17) Trial
Study Overview
Status
Detailed Description
This is an observational follow-up study subsequent to the ConfIdeS study (20-HMedIdeS-17, NCT04935177) in highly sensitized patients who were randomized to imlifidase or SoC desensitization prior to kidney transplantation with a deceased donor graft, or, if SoC perioperative treatment has been deemed not appropriate, wait for a more immunologically compatible organ offer.
After the patients have given written informed consent to participate in the follow-up they will be included in the study and followed until 5 years after randomization in the ConfIdeS study.
Most of the assessments in this study are already part of the follow up within SoC for these patients. During the local clinic routine follow-up visits at year 2, 3 and 5 after randomization in the ConfIdeS study, information about patient survival, wait-list status, graft survival, kidney function, and health related quality of life will be evaluated.

Cohorts and Interventions
Group / Cohort |
Intervention / Treatment |
---|---|
Imlifidase administered in the ConfIdeS study
|
Imlifidase is an immunoglobulin G (IgG)-degrading enzyme of Streptococcus pyogenes that is highly selective towards IgG.
The cleavage of IgG generates one F(ab')2- and one homodimeric Fc- fragment and efficiently neutralizes Fc-mediated activities of IgG.

Best available treatment administered in the ConfIdeS study
|
Institution-specific desensitization treatment prior to kidney transplantation in the ConfIdeS study OR remain on wait list for a more compatible organ offer if desensitization with institutional protocol is not appropriate

|
Graft failure-free survival rates at 3 and 5 years
Time Frame: 3 and 5 years after randomization in the ConfIdeS study
|
Graft failure-free survival is defined as time from randomization to the fist of either graft failure or death
|
3 and 5 years after randomization in the ConfIdeS study
|
Graft survival rates at 3 and 5 years

|
3 and 5 years after randomization in the ConfIdeS study
|
Number of patients per wait-list category
Time Frame: 3 and 5 years after randomization in the ConfIdeS study
|
The different wait-list categories are: transplanted, active, temporary inactive, inactive, or deceased
|
3 and 5 years after randomization in the ConfIdeS study
|
Mean estimated glomerular filtration rate (eGFR) at 3 and 5 years
Time Frame: 3 and 5 years after randomization in the ConfIdeS study
|
eGFR is a measure of kidney function.
eGFR will be calculated based on p-creatinine according to the modification of diet in renal disease (MDRD) equation.
Kidney disease is characterised by a decreased eGFR value.
eGFR will be set to zero, for randomized patients who do not undergo transplantation, lose their graft or die.

3 and 5 years after randomization in the ConfIdeS study
|
Proportion of patients with biopsy- and serology confirmed antibody-mediated rejection (AMR)
Time Frame: 3 and 5 years after randomization in the ConfIdeS study
|
3 and 5 years after randomization in the ConfIdeS study
|
|
Proportion of patients with biopsy confirmed cell-mediated rejection
Time Frame: 3 and 5 years after randomization in the ConfIdeS study
|

|
Treatment of graft rejection episodes
Time Frame: 3 and 5 years after randomization in the ConfIdeS study
|
Any treatments given during rejection episodes will be recorded
