Bringing it all together

Without PROphet®

Guidelines group therapy choices into 2 patient groups:

PD-L1 ≥50%
Single-agent immunotherapy or immunotherapy + chemotherapy

PD-L1 <50%
Immunotherapy + chemotherapy

With PROphet®

PROphet® stratifies therapy choices into
6 patient groups:

PD-L1 ≥50% + PROphet® POSITIVE: Single-agent
PD-1/PD-L1 inhibitor

PD-L1 ≥50% + PROphet® NEGATIVE: Combination
PD-1/PD-L1 inhibitor + chemotherapy

PD-L1 1-49% + PROphet® POSITIVE: Combination
PD-1/PD-L1 inhibitor + chemotherapy (preferred)

PD-L1 1-49% + PROphet® NEGATIVE: Low to moderate benefit with PD-1/PD-L1 inhibitor + chemotherapy

PD-L1 <1% + PROphet® POSITIVE: Combination
PD-1/PD-L1 inhibitor + chemotherapy

PD-L1 <1% + PROphet® NEGATIVE: Poor outcome on PD-1/PD-L1 inhibitor with or without chemotherapy. Consider alternative guideline-approved therapies or first-line clinical trial

Provider FAQ

What is the PROphet® NSCLC test?

PlusMinus

PROphet® NSCLC guides first-line PD-1/PD-L1 inhibitor treatment decisions for metastatic NSCLC patients by accurately predicting likelihood of clinical benefit and overall survival when administered as a single agent vs. in combination with chemotherapy.

How was PROphet® NSCLC validated?

PlusMinus

The PROphet® model was developed  based on clinical, demographic, and proteomic data of over 600 patients within the framework of an ongoing clinical study conducted by OncoHost (PROPHETIC; NCT04056247). To date, the trial has over 1,700 patients recruited across 40 sites worldwide, making it one of the largest prospective cohorts in the precision oncology field.

Plasma was isolated from the blood and profiled via the SomaScan® Discovery Assay v4.1[2-3], and the resulting proteomic profiles were analyzed in conjunction with patient clinical data. The clinical benefit prediction algorithm was developed to identify patients who are more likely to benefit from PD-1/PD-L1 inhibitor treatment. Patient clinical benefit probability is predicted and linearly transformed to a PROphet® Score between 0 to 10.

The PROphet® NSCLC test is supported by a blinded validation demonstrating that it accurately predicts a patient’s clinical benefit and associated overall survival differences with single-agent versus combination treatment plans.

How does PROphet® NSCLC differ from other NGS testing/comprehensive profiling?

PlusMinus

Proteomics and next-generation sequencing (NGS) are complementary approaches in understanding cancer dynamics. PROphet® NSCLC focuses on proteomic pattern analysis, revealing biomarkers that indicate biological processes within the tumor and the body, influencing treatment success.

On the other hand, NGS examines the genomic and genetic makeup of the tumor, identifying crucial genetic alterations which guide your overall treatment planning. Integrating proteomic analysis with NGS can provide you with valuable insights into your patient’s tumor growth, characteristics, and predicted response to treatment.

Why is proteomics valuable in determining immunotherapy resistance?

PlusMinus

While immunotherapy has shown remarkable success in some cases, not all patients respond equally, and resistance to treatment can be a significant challenge.

Proteomics provides insights into the complex interactions between the immune system and cancer cells at a molecular level. By analyzing protein expression patterns, we can identify biomarkers that predict patient response to immunotherapy.

Proteomics also provides insights into the tumor microenvironment, revealing crucial interactions between cancer and immune cells. The tumor microenvironment plays a vital role in influencing the effectiveness of immunotherapy, and proteomics can provide information about the types and quantities of immune cells present, as well as the signaling molecules and proteins secreted by both cancer and immune cells. Understanding these interactions can help reveal mechanisms of resistance and suggest ways to overcome them.

By leveraging proteomic insights, we can tailor treatments based on individual patient profiles, leading to more effective and personalized cancer care and, ultimately, improving patient outcomes.

How is the patient’s blood drawn for PROphet® NSCLC?

PlusMinus

OncoHost will send a mobile phlebotomist to draw one pre-treatment blood test from the comfort of the patient’s home or at the patient’s preferred location. OncoHost will be in touch with the patient directly to coordinate the appointment.

Does OncoHost provide in-clinic blood draws?

PlusMinus

Yes. Contact our Client Services team to coordinate this option for your clinic: contact@oncohost.com or 1-855-950-2112.

How much plasma is required for the test?

PlusMinus

0.2 microliters.

What is the patient eligibility criteria to order the PROphet® NSCLC test?

PlusMinus

The patient must be newly diagnosed with metastatic non-small cell lung cancer (NSCLC) and immunotherapy naïve.

Does OncoHost also provide PD-L1 test results?

PlusMinus

No, PD-L1 testing should be completed using your regular provider. PROphet® NSCLC is ordered at the same time as NGS and PD-L1 so that all results are available to you at the time of treatment planning.

Combining the PROphet® NSCLC test results with the PD-L1 score provides additional information on the patient’s expected response, which may support the choice of first-line therapy and affect the patient over time. 

PROphet® NSCLC predicts differential overall survival (OS) and progression-free survival (PFS) outcomes when combined with PD-L1 expression level.

What if the patient’s report shows a PROphet® NEGATIVE result?

PlusMinus

This will provide you with valuable insights into your patient’s first-line treatment plan, offering treatment considerations for therapies they are likely to respond to based on their personalized proteomic analysis.

What if the patient’s report shows a PROphet® POSITIVE result?

PlusMinus

This means that the patient has a high likelihood of achieving clinical benefit on an approved PD-1/PD-L1 inhibitor immunotherapy regimen.

How do I order the PROphet® NSCLC test for my patient?
