About Pyxis Diagnostics

About Pyxis Diagnostics

The human immune system can efficiently eradicate even widespread metastatic tumors, delivering durable survival benefit to cancer patients. Unfortunately, only a small subset of cancer patients benefit from immunotherapy; the rest lose valuable time and may suffer from diverse adverse events. Hence, biomarkers that predict a patient’s response to immunotherapy are in urgent need.

Immune Related Parameters

Immune Related Parameters

Over the years, several parameters were found to correlate with response to immunotherapy. The most prominent immune-related parameters are:​

  1. The various immune subsets’ relative abundance within the tumor

  2. The expression and co-expression patterns of different Immune Check Point (ICP)-related molecules on each cell-subset

  3. The immune state of each subset (e.g., activated, exhausted, its cytokine-polarization, metabolic state etc.)

Our Diagnostic Platform

Our Diagnostic Platform

Our diagnostic platform integrates all prominent immune parameters defined above and more, generating unique delineation of the tumor - immune - stroma microenvironment formed within human tumors.

This approach may provide better understanding on the structure and function of the inter-cellular communication network (ICCN) that protect tumor tissue from immune-mediated assault


Pyxis Mission

PyxisDX Develops a diagnostics platform for predicting IO drug response, and for the discovery of new drug combinations, by mapping the tumor-immune communication network.
