Our Mission

Moving transplant care from reactive management toward precision-guided surveillance.

Built on the data-driven methodology of the iBox prognostic system — now an EMA-qualified surrogate endpoint for clinical trials.

Despite advances in immunosuppression, kidney transplant recipients still face significant risks from rejection, viral infection, disease recurrence and graft failure. Early detection and accurate risk stratification remain unmet needs.

Single-center studies, while foundational, cannot account for the heterogeneity in immunological risk, immunosuppressive strategies and clinical practice that exists across transplant populations worldwide. TRINITY was established to close this gap — building a shared, evolving research infrastructure that enables multicenter validation at scale.

Harmonized Variables
Active Science

Four areas of investigation on one shared infrastructure.

Each project operates on the same harmonized datalake, with distinct scientific objectives and data requirements.

01 · Prognostication Abstract visualization of an allograft survival risk model

Extended validation of the iBox system

A prognostic system for kidney allograft failure, integrating eGFR, proteinuria, histology and immunology. Already validated across seven countries and randomized trials; TRINITY extends it to new centers and populations.

02 · Biomarker Donor-derived cell-free DNA strands over a kidney biopsy

Donor-derived cell-free DNA

A non-invasive biomarker of graft injury. TRINITY validates the dd-cfDNA model across cohorts and evaluates its association with Banff 2022 microvascular inflammation phenotypes and early post-transplant settings.

03 · Virology BK polyomavirus particles and longitudinal viral-load curves

BK polyomavirus

One of the largest international BK cohorts in kidney transplantation — integrating viral loads with biopsy findings, dd-cfDNA and outcomes to identify risk factors and build progression-risk tools.

04 · Recurrence Histology montage of recurrent native kidney disease

Recurrence of native disease

An undercharacterized contributor to graft loss. TRINITY defines the incidence and impact of recurrence across IgA nephropathy, FSGS, membranous and membranoproliferative disease — distinguishing recurrence from rejection.

Data Infrastructure

A living datalake — built for continuous flow, not static snapshots.

Data are extracted locally after IRB approval and transferred through secure, end-to-end encrypted protocols.

01

Ingestion & Integration

Local extraction following IRB approval, then secure transfer into the consortium pipeline.

02

Transform

Cleaning, harmonization and mapping to a common data model of 400+ variables.

03

Secure Storage

Integration into a centralized, cloud-based repository with end-to-end encryption.

04

Analyze & Visualize

Real-time querying, visualization and machine-learning pipelines on harmonized data.

Principal Investigator

Alexandre Loupy, MD, PhD

Head of the PITOR Institute

Pr. Loupy's research focuses on the development and validation of prognostic models and molecular biomarkers in kidney transplantation. He led the development of the iBox system and the large-scale evaluation of dd-cfDNA for rejection detection.

TRINITY's coordination — data harmonization, quality control and analytical planning — is centrally managed at the Paris Institute for Transplantation & Organ Regeneration. The initiative convenes biannually to review results and define research priorities.
