Blood-based Monitoring

Detect progression early after cancer treatment initiation.

Is the therapy


Best decision earlier

DetermaCNI™ testing detects progression early, often after one cycle of treatment, and requires NO Tissue – saving time and significant costs.1

Non-Surgical Candidates

Typically, patients with advanced cancer

  • Evaluating early phase therapies
  • Targeted therapies
  • ICI or novel IO combinations

Resistance and progression

Only a fraction of patients being treated for cancer
respond to treatment.2

Identifying progression early allows physicians to change the course of therapy quickly when time is of the essence. For pharmaceutical companies conducting clinical trials, DetermaCNI can de-risk clinical trials by identifying non-responders early.3

In published studies, DetermaCNI identified progressors early and with high accuracy. Patients with elevated DetermaCNI scores were more than 95% likely to experience clinical progression (>95% PPV).
