Reaction Biology, a drug discovery CRO with offices in Pennsylvania and Germany, and 4HF Biotec GmbH, a bioinformatics firm based in Freiburg, Germany, have announced a new cell-based service offering that combines Reaction Biology’s ProLiFiler cell assay service with 4HF’s Biomarker Analysis and MOA Finder tools.
 
4HF Biotech has built a comprehensive database including data from more than 1,800 preclinical samples comprising multiple cancer datasets that are integrated into a single platform for visualization and statistical analysis. The data relevant for the Biomarker Analysis Tool are mutations (whole-exome sequencing), gene copy numbers, and gene expression data. The MoA Finder tool aims to identify the mode of action (MoA) of the test compound by comparing the sensitivity profile of the drug candidate to that of known drugs.
 
Results of Reaction Biology’s 140 cell line assay will be put through both tools of Biomarker Analysis and MOA Finder to give customers a comprehensive understanding of their drug candidates. For Biomarker Analysis, a correlation analysis is performed for each cell line to determine the correlation of the drug sensitivity to each gene with regard to the expression level, mutation status, and/or somatic copy number. For MoA Finder, the test compound’s sensitivity profile is compared to more than 700 drugs for which the Mode of Action is known.
 
“This will give our customers deep insight into the likely genetic response to the drug candidates they test with us,” said Dr. Haiching Ma, chief science officer of Reaction Biology. “A cell profile study can shine a spotlight on what a compound is doing, but combining that with 4HF’s bioinformatics creates a roadmap for our customers’ further development.”
 
“Seeing the phenotypic effects of a compound is only half the information required for an informed drug discovery decision,” added Dr. Vincent Vuaroqueaux, CSO of 4HF. “Our bioinformatic approach to building an oncological drug response profile will provide the other half. The Reaction Biology platform is the perfect application for our data analytics.”
 
The service will be performed at Reaction Biology’s labs, collaborating with 4HF for analysis. Both companies’ labs are in Freiburg.
