Capabilities

At Precision, we understand that tissue samples are limited and you need to maximize the amount of data generated from small amounts of tissue. Our team of scientists can develop, validate, and implement IHC assays to support early stage or exploratory proof of concept studies, through Phase III studies that require a CLIA validated assay.

We handle all aspects of IHC biomarker analysis including:

  • Custom assay development, qualification & validation, including scoring system
  • Logistical process for sample collection
  • Global deployment of custom kitting
  • Sample receipt and tissue processing
  • Centralized pathology reading with manual scoring by a pathologist or automated software-based scoring
  • Real time analysis for patient screening & enrollment (CLIA)

We also can develop an IHC assay into a companion diagnostic.

Couple IHC biomarker assays with our other technologies to generate robust data sets

Clinical biomarkers go far beyond traditional IHC. We offer customized work flows across our integrated platform to generate incredibly rich data sets.

  • Look at multiple tissue biomarkers for immunophenotyping with multiplex quantitative immunofluorescence image analysis
  • Liquid biopsies offer an alternative when tissues are not available for serial assessment of pharmacodynamic biomarkers
  • Leverage our genomics applications to understand the genetics behind the proteomic results
  • Immunophenotype blood samples from the same patient via flow cytometry for in depth analysis of the immune system in both the tumor and blood
  • Detect chromosomal abnormalities by FISH or mRNA by ISH in the same tissue samples used for IHC

Case Study: Patient stratification using biomarkers from biopsies

Precision developed an IHC assay for patient study enrollment by P-Cadherin expression in tumor biopsies:

  • Assay development and customized kitting generation and shipment
  • Development of a semi-quantitative IHC scoring index (SI) to compare P-Cadherin staining intensity and prevalence from sample to sample
  • IHC pathology analysis by scoring index; rapid turnaround of results reported within 72 hours of receipt

This rapid turnaround of scoring index data enabled P-Cadherin expression to be utilized as a criterion for inclusion in the study.

Integrating biomarker and clinical trial data

To help researchers understand and interpret biomarker assay data in the context of other assays as well as the clinical trial data, Precision provides the option of managing and analyzing data using our proprietary QuartzBio Translational Informatics platform.
