Pharmacogenetics International Expertcenter

Research is aimed at discovery and implementation of DNA analysis for personalizing drug therapy

About our research group/lab

Our research

Pharmacogenetics

Research of the group has a focus on the value and subsequent clinical implementation of  pharmacogenetics. Current topics are:

  1. Oncology (capecitabine, irinotecan, paclitaxel, docetaxel, tamoxifen, nivolumab, pembrolizumab)
  2. Immunosuppressants (tacrolimus, cyclosporine, MMF)
  3. Opioids (morphine, tramadol, propofol, oxycodone).
  4. Antidepressants/antipsychotics

 

Opioid dependency

Very recent, a 16 gene panel has been introduced to the FDA to be able to predict opioid dependency. We are investigating the clinical validity of this test, and its implementation to control the widespread opioid dependency in The Netherlands. For this, we have a close and exclusive collaboration with a US based company.

 

Cell free DNA

A new, non-invasive and sensitive biomarker approach is to make use of the detection of DNA variants in blood:  cell free DNA analysis. We investigate this approach in three research lines:

  1. NSCLC. Analysis of EGFR T790M, L858R, exon19 skipping and C797S mutations can guide decisions on the use of osimertinib.
  2. Prostate cancer. Analysis of exosomal RNA of the AR-V7 transcript has added value in the treatment of castrate resistant prostate cancer
  3. Heart/kidney transplantation. Monitoring of graft rejection by using cfDNA techniques.

 

Prostate cancer & Cardiac Biomarkers

This research is focusing on new markers for the early detection of  prostate cancer (collaboration with Dept. Urology, Prof. Chris Bangma) and new markers for the early detection of acute myocardial infarction (collaboration with Dept. Cardiology, Prof. Eric Boersma).
