PrismRA For Physicians

PrismRA Delivers Precision Medicine to You and Your Patients with Rheumatoid Arthritis

PrismRA is a blood-based, precision medicine, molecular signature response classifier (MSRC) that predicts inadequate response to TNFi therapy in rheumatoid arthritis.

90% Positive Predictive Value

PrismRA delivers proven, data-driven, precision medicine validated to predict TNFi inadequate response.

Rheumatologists Are Forced to Take a Trial-and-Error Approach to Therapy Selection

Up to 90 percent

of patients with RA are treated with TNFi therapies as first-line biologic or targeted synthetic DMARD3,4

Only About One-Third

of patients with RA reach ACR50 at 6 months with b/tsDMARD after failing methotrexate5,6

Knowing the patient’s PrismRA score helps guide decision making to stop the current trial-and-error approach

The PrismRA Molecular Signature Response Classifier Was Developed to Guide Therapy Selection

To develop PrismRA, Scipher started with approximately 7,000 biological features. Using artificial intelligence, we identified and ranked the top 23 features most predictive of inadequate response to TNFi therapies.

An Actionable, Easy to Interpret, Single Page Result to Guide Therapy Selection

    • The PrismRA result shows whether a TNFi inadequate response signature is detected.
    • The PrismRA score is reported on a scale of 1 to 25. The higher the score, the more likely the patient is to have an inadequate response to TNFi therapies.
    • Based on the PrismRA score, PrismRA predicts your patient’s probability of response to TNFi therapy.

    PrismRA Provides Unique Insights to Guide Treatment Decisions

    TNFi High Signal Chart

    >10.6 is a high signal of inadequate response and the patient has a 10% chance of responding to a TNFi

    TNFi Very High Signal Chart

    >18.5 is a very high signal of
    inadequate response and the patient has a 5% chance of responding to a TNFi

    TNFi No Signal Chart

    <10.6 indicates that no signal of inadequate response was detected and the patient may be likely to respond to a TNFi*

    *A low PrismRA score does not ensure a positive response.
