PROphet® is a unique plasma-based, proteomic pattern analysis tool that uses a single blood sample to accurately guide first-line immunotherapy decision-making.

A new dimension to personalization

PROphet® combines bioinformatics, system biology, proteomic pattern recognition and machine learning to provide clinicians with actionable clinical insights, optimal therapy choices, and a better understanding of their patients’ personalized cancer dynamics.

PROphet® scans approximately 7,000 proteins in a patient's blood plasma and delivers a report predicting their likelihood of obtaining clinical benefit from anti-PD-1/PD-L1 treatment plans.

Currently available for the following indications

Non-Small Cell
Lung Cancer (NSCLC)
(Coming Soon)

With just one pre-treatment blood test, PROphet® produces a
personalized report answering an important clinical question:

What is the optimal first line of therapy for this patient?
We apply proprietary computational models that analyze the proteomic patterns in the patient’s plasma and identify those proteins that are associated with resistance to treatment.

Clinical Validation

The PROphet® model was developed using patient blood samples and clinical data collected within the framework of an ongoing clinical study conducted by OncoHost (PROPHETIC; NCT04056247). In brief, pre-treatment blood samples were collected from 630 advanced stage non-small cell lung cancer (NSCLC) patients, out of which 545 were undergoing anti-PD-1/PD-L1 therapy with or without chemotherapy, and 85 were being treated with chemotherapy.

Patient clinical data were recorded, including demographics, clinical characteristics, and clinical benefit. Blood plasma was profiled by the SomaScan® Discovery Assay v4.1, and the resulting proteomic profiles were analyzed in conjunction with patient clinical data. Specifically, a proprietary prediction algorithm was developed to identify proteomic patterns associated with clinical benefit from anti-PD-1/PD-L1 treatment.
