Evaluation of a Marine OXYgen Carrier: HEMO2Life® for hypOthermic Kidney Graft Preservation, Before Transplantation (OXYOP)
|ClinicalTrials.gov Identifier: NCT02652520|
Recruitment Status : Completed
First Posted : January 12, 2016
Last Update Posted : March 19, 2018
Kidney transplantation is the treatment of choice for end stage renal diseases, increasing life expectancy and quality of life. Improvement in organ preservation is a critical issue in this context.
This is a safety study evaluating the use of an oxygen carrier HEMO2Life® as an additive in organ preservation solution in kidney transplantation.
|Condition or disease||Intervention/treatment||Phase|
|End Stage Renal Diseases||Procedure: HEMO2Life® use in organ preservation solution||Phase 1|
Security of the use of HEMO2Life® will be analyzed by collecting all events within the first 3 months in terms of :
- HEMO2Life® adverse effects
- graft safety
- recipient safety (any adverse event) Accountability search will be achieved for each of these events.
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||60 participants|
|Intervention Model:||Single Group Assignment|
|Masking:||None (Open Label)|

Experimental: Kidney transplantation
HEMO2Life® use in organ preservation solution. Grafts removed and transplanted locally within the 6 kidney transplant centers participating in the study will be preserved with Hemo2life.
Procedure: HEMO2Life® use in organ preservation solution
The surgeon decides whether the local transplant kidney may be part of the study and whether it should be stored in static cold storage or machine perfusion. The transplant kidney will be perfused in situ before procurement with the Belzer UW® cold storage solution furnish by the BridgetoLife company. HEMO2Life® will then be added to preservation solution.
- HEMO2Life® adverse effects [ Time Frame: During 3 months ]All incidents and events of interest occurring during the use of HEMO2Life® will be collected
- Graft safety [ Time Frame: During 3 months ]Collecting any complication with particular attention to mascroscopic aspect, contamination of the conservation solution, surgical difficulties and thrombosis, primary non function, delayed graft function, slow recovery of graft function, acute rejection, or any other graft complications.
- Recipient safety (any adverse event) [ Time Frame: During 3 months ]All adverse events, even unrelated to HEMO2Life®, occuring during the first 3 months after transplantation will be collected. Vital signs and laboratory evaluations will be collected at D0, D1, D3, D7, D14, M1, M2 and M3 to evaluate the recipient safety
- Comparison of the graft survival criteria with a control population [ Time Frame: Baseline to 12 months ]Results will be compared with patients from a case control group of grafts transplanted at the same time in the 4 transplant centers from the Spiesser group (Tours, Poitiers, Brest, Limoges). Groups will be formed after matching on sex, age and cold ischemia time thanks to the Astre database regrouping the data of all the transplant teams from the Spiesser group.
- Histological evaluation of the graft on biopsies [ Time Frame: pre-implantation to 3-month biopsies ]All biopsies are interpreted locally and classified according to the Banff classification. Interstitial fibrosis quantification using automated quantitative image analysis of biopsies will also be performed from each biopsy.
- Analysis of markers involved in kydney regeneration and neovascularization and markers of cellular stress. [ Time Frame: Baseline to 12 months ]Analysis of blood and urine biomarkers at each visit.
