About this study
Official title: Histopathological Analysis of Renal Biopsies With Dynamic Full-field Optical Coherence Tomography, a Comparison to Conventional Histopathological Findings in Kidney Transplant Recipients
Banff classification stands as gold standard and international consensus for the identification, diagnosis and categorization of renal allograft pathology. In addition to multiple revision dedicated to the clarification and refinement of these diagnostic categories, a special attention is now dedicated to the development of automated protocols serving the use of artificial intelligence in digital pathology. To be integrated in the actual early post-transplant monitoring procedure, such original approach is considered to match various growing expectations of clinicians and pathologists regarding the future of transplant nephropathology : decrease inter-observer variability, reduce human errors and limit time-consuming analysis of kidney biopsy. Among these, an accelerated reading and access to Banff diagnostic criteria could help initiating both appropriate and immediate treatment to improve graft survival in kidney transplant recipients. Yet conventional histopathology still requires the preparation of a paraffin block, sections as well as subsequent colorations that altogether delay the final pathological diagnosis and urge the need for additional diagnostic modalities. Designed to overcome this critical limitation, the HARBOR study intends to test the performance of direct histopathological examination of fresh kidney biopsy with full-field optical coherence tomography for the identification of Banff elemental lesions and diagnostic categories.

What is being measured
The primary outcome is the main question the study is designed to answer.
Banff lesion scores based on dynamic full-field optical coherence tomography measurement
Provide a better understanding of the ability of dynamic full-field optical coherence tomography to identify and score the usual Banff lesions comprising interstitial inflammation, tubulitis, intimal arteritis, glomerulitis, peritubular capillaritis, interstitial fibrosis, tubular atrophy, vascular fibrous intimal thickening, glomerular basement membrane double contours, mesangial matrix expansion, arteriolar hyalinosis, hyaline arteriolar thickening, total inflammation and inflammation in the area of both interstitial fibrosis and tubular atrophy.
Note that the the Banff scoring system has three grades for each lesion : from mild (1) to moderate (2) and severe (3). In each case, the higher the score the worse the outcome, according to the 2018 Reference Guide to the Banff Classification of Renal Allograft Pathology
Measured: Outcome measure is assessed 15 days following kidney transplant biopsy
Secondary outcomes (1)
Banff diagnostic categories based on dynamic full-field optical coherence tomography measurement
Provide a better understanding of the ability of dynamic full-field optical coherence tomography to identify the usual Banff diagnostic categories comprising normal biopsy (or biopsy with nonspecific changes), biopsy with antibody-mediated changes, biopsy considered borderline or suspicious for acute T cell-mediated rejection, biopsy with T cell-mediated rejection, biopsy with both interstitial fibrosis and tubular atrophy, biopsy with changes not considered to be caused by acute or chronic rejection Note that the Banff Diagnostic Categories form the core of the Banff Classification of Renal Allograft Pathology according the 2018 Reference Guide to the Banff Classification of Renal Allograft Pathology
Measured: Outcome measure is assessed 15 days following kidney transplant biopsy

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
Banff classification stands as gold standard and international consensus for the identification, diagnosis and categorization of renal allograft pathology. In addition to multiple revision dedicated to the clarification and refinement of these diagnostic categories, a special attention is now dedicated to the development of automated protocols serving the use of artificial intelligence in digital pathology. To be integrated in the actual early post-transplant monitoring procedure, such original approach is considered to match various growing expectations of clinicians and pathologists regarding the future of transplant nephropathology : decrease inter-observer variability, reduce human errors and limit time-consuming analysis of kidney biopsy.

Questions about this trial
What is this clinical trial studying?
An observational study of Tomography, Optical Coherence and Kidney Transplantation, run by Centre Hospitalier William Morey - Chalon sur Saône at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 1 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 3 Jan 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Banff lesion scores based on dynamic full-field optical coherence tomography measurement (time frame: Outcome measure is assessed 15 days following kidney transplant biopsy). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05635136, which also lists 6 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Jan 2024.
