About this study

Official title: Circulating Donor-Derived Cell-free DNA in Blood for Diagnosing Acute Rejection in Kidney Transplant Recipients

This is a prospective, multicenter, observational study of kidney transplant subjects where blood specimens, intended for dd-cfDNA and other future research purposes, will be drawn after transplant

Read the detailed description

This is a prospective, multicenter, observational study of kidney transplant subjects where blood specimens, intended for dd-cfDNA and other future research purposes, will be drawn after transplant periodically and also after the treatment of acute rejection up to 8 weeks post treatment. The blood samples and all relevant clinical data will be provided to CareDx scientists for laboratory assay of dd-cfDNA levels and correlation of dd-cfDNA levels with the clinical features of the subjects.

The primary objective of the study is to correlate circulating dd-cfDNA to clinical and sub-clinical acute rejection in renal allograft recipients. The secondary objective of the study is to correlate circulating dd-cfDNA to renal function, both serum creatinine and estimated glomerular filtration rate [eGFR]).

Kidney Transplant RecipientsAdult living and deceased donor kidney transplant recipients will be eligible to participate in this study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Clinical T cell as well as antibody mediated acute rejection

    Measured: Occurring within 12 months post transplant

  2. Sub-clinical T cell as well as antibody mediated acute rejection

    Measured: Occurring within 12 months post transplant

  3. Composite of clinical and sub-clinical T cell as well as antibody mediated acute rejection

    Measured: Occurring within 12 months post transplant

Secondary outcomes (2)

  1. eGFR (estimated Glomerular Filtration Rate [mL/min]): will be derived from serum creatinine level, corrected for variables, using the CKD-RPI (Chronic Kidney Disease Epidemiology Collaboration) equation

    Measured: 24 months

  2. Renal allograft injury from BKV nephritis, CNI toxicity, acute pyeloenephrtiis and recurrent disease confirmed by renal histology

    Measured: 24 months

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?

Clinical T cell as well as antibody mediated acute rejection (time frame: Occurring within 12 months post transplant). The study lists 3 primary outcomes in all. 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 NCT02424227, which also lists 9 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 17 Dec 2018; AzTrials last refreshed its copy on 7 Nov 2026.
