Early Phase Clinical Trials in Oncology

Our group conducts and designs clinical studies to develop potential new drugs that may be of benefit for cancer patients

About our research group/lab

Our research

Early Phase Clinical Studies

We participate in first-in-human studies and increasingly in expansion cohorts targeting specified patient populations either in collaboration with pharmaceutical companies or independently.

Genomic Prescreening of Patients

In collaboration with the Hartwig Medical Foundation we will start screening patients for eligibility in trials using Whole Genome Sequencing, allowing us to increase the likelihood of benefit for the patients we enroll into Early Phase Clinical trials.

Identifying Patient Characteristics of Trial Participants

Patients that choose to participate in Early Phase Clinical trials should derive some benefit and using this research we aim to increase our understanding of how to achieve optimal patient benefit.
