Haufen Diagnostic Biomarkers of BK Renal Disease

This study is enrolling participants by invitation only.

Collaborator:
Astellas Pharma US, Inc.
Information provided by (Responsible Party):
Volker Nickeleit, MD, University of North Carolina, Chapel Hill
ClinicalTrials.gov Identifier:
NCT01094691
First received: March 25, 2010
Last updated: April 17, 2017
Last verified: April 2017
  Purpose
To prospectively test whether the detection of three-dimensional, cast-like polyomavirus aggregates, termed Haufen, in voided urine samples can serve as an accurate biomarker of intra-renal disease, i.e. polyoma-BK-virus nephropathy (PVN). We want to correlate the detection of 'Haufen' with histologic findings made in renal biopsies as well as signs of polyomavirus activation, i.e. viremia and viruria. The prospective study is designed to further validate our retrospective findings (manuscript in press, J Am Soc Nephrology) and more specifically to correlate 'Haufen' shedding with the histologically confirmed course of PVN.

Condition Intervention
Polyoma Virus Nephropathy Procedure: Renal Allograft Biopsy

Study Type: Interventional
Study Design: Intervention Model: Single Group Assignment
Masking: No masking
Primary Purpose: Diagnostic
Official Title: Polyomavirus Aggregates, Haufen, in Voided Urine Samples as Diagnostic Biomarkers of Intra Renal BK-virus Disease: a Prospective Proof-of-concept Study

Primary Outcome Measures:
  • Correlate Haufen, urine and plasma data with the clinical presentation and - in selected cases - with renal biopsy findings. [ Time Frame: The biopsy will be performed when urine is determined to be Haufen negative ]

Estimated Enrollment: 10
Study Start Date: November 2008
Estimated Study Completion Date: December 2019
Estimated Primary Completion Date: July 2019 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Renal Allograft Biopsy Procedure: Renal Allograft Biopsy
A renal allograft biopsy will be performed when the urine is determined to be Haufen negative.
