TrueMRD Monitoring Test for Muscle-Invasive Bladder Cancer  

The TrueMRD for MIBC test provides clinicians and patients with whole-genome insights for minimal residual disease detection of muscle-invasive bladder cancer.

What is the TrueMRD Monitoring Test for MIBC?

Minimal residual disease (MRD) refers to the presence of residual cancer that remains undetectable by conventional imaging following treatment. MRD can be detected by measuring circulating tumor DNA (ctDNA) which are fragments of DNA released by cancer cells into the bloodstream. 

The TrueMRD for MIBC test is a whole-genome, tumor-informed test that detects ctDNA in a patient’s blood after bladder cancer treatment. The test is for patients with muscle-invasive bladder cancer (cT2-cT4, N0-N2) who have had definitive therapy, with no current evidence of active disease.

How the TrueMRD for MIBC test works

The TrueMRD for MIBC test leverages whole-genome sequencing to create a personalized signature that is unique to each patient’s cancer. It then uses this signature to look for recurrence after definitive therapy.

Specimen collection

1. FFPE tissue collection: Obtained from archived tissue from the transurethral resection of bladder tumor (TURBT).

2. Blood sample collection: Collected 2-4 weeks after definitive therapy for ctDNA analysis and personal fingerprint generation.

Signature generation

Using whole-genome sequencing (WGS), the tumor DNA from the archived tissue is compared with normal germline DNA from healthy cells found in the blood (buffy coat). 

From this analysis, a unique signature is created for each patient, the TrueMRD Personalized Signature, which is like a “genome-wide molecular fingerprint”. 

This personal signature becomes the reference for all future monitoring.

Initial baseline result

Plasma from the initial blood sample collected 2-4 weeks after definitive therapy is used for ctDNA analysis and a TrueMRD Baseline Result is obtained.  

Results are reported as:

  • Positive (+) MRD detected
  • Negative (-) MRD not detected

Subsequent monitoring 

Each subsequent TrueMRD test uses whole-genome sequencing to detect the patient’s TrueMRD Personalized Signature, indicating whether ctDNA is detectable.

Surveillance for muscle-invasive bladder cancer relies heavily on imaging right now, which has real limitations in detecting early recurrence. A whole-genome MRD test that can help identify disease recurrence, often months before imaging, gives clinicians a powerful new tool. The expanding clinical evidence behind Veracyte’s MRD platform is compelling, and Medicare coverage brings this test to patients at a pivotal time when the landscape of treatment for muscle-invasive bladder cancer is rapidly changing with the development of more effective systemic therapies and expanding bladder-sparing approaches.”5

TrueMRD for MIBC detects bladder cancer recurrence months earlier than imaging

A prospective study published in European Urology evaluated over 900 blood and tissue samples from 112 patients with MIBC treated with neoadjuvant chemotherapy and radical cystectomy. In this study, the TrueMRD MIBC Test detected disease recurrence a median of 131 days earlier than imaging.4
