Cxbladder® Monitor

Cxbladder® Monitor is a urine genomic test designed for patients with non-muscle invasive bladder cancer (NMIBC) who require surveillance monitoring for recurrence. It offers a non-invasive alternative that can reduce the burden of repeated cystoscopy. In suitable patients with sustained negative results, Monitor can replace cystoscopy in the long term following shared decision-making between clinician and patient.

Patients undergoing surveillance for recurrent non-muscle invasive bladder cancer (NMIBC) who require regular monitoring. Can alternate with cystoscopy to reduce the frequency of invasive surveillance, or replace cystoscopy in low-risk patients with consistently negative results.

⚠ Not intended for:

Not for first-line diagnosis of bladder cancer. Not for high-grade or muscle-invasive bladder cancer surveillance without cystoscopy. Not a replacement for cystoscopy where clinical concern is present.

  • Cxbladder Monitor Score < 3.5
    • Low probability of recurrent urothelial carcinoma
  • Cxbladder Monitor Score >= 3.5
    • Cannot rule out urothelial carcinoma and a clinician-directed protocol to determine if recurrent Urothelial Carcinoma is present is warranted

NMIBC accounts for ~75% of bladder cancer cases. Standard surveillance requires regular cystoscopy, which is invasive, costly, and burdensome for patients. Published clinical studies show Cxbladder Monitor has high sensitivity for detecting recurrence, enabling clinicians to alternate with or substitute cystoscopy in appropriate patients.
