About

Our knowledge on the genetic mutations in cancer is rapidly expanding and we are increasingly testing drugs in mainly metastatic cancer patient populations with rare mutations. Successful examples of this new strategy are ALK inhibitors in ALK translocated NSCLC (less than 5% frequency) and EGFR inhibitors in EGFR mutant NSCLC (approximately 5% frequency). Selecting molecularly stratified patient populations for studies benefits the patient as it increases the odds of obtaining benefit from experimental treatment, especially in early clinical trials. Moreover it increases the speed and efficacy of drug development as signs of efficacy are picked up in earlier phases. Therefore, broad screening of molecular lesions in the tumors of patients that are being considered for participation in trials is crucial. This pre-selection increases our ability to perform several trials in parallel and thus include more patients in more meaningful trials. With the still dismal prognosis of patients with metastatic cancer, increasing the accrual rate to pivotal trials in selected patient populations is a key factor in improving prognosis.

The advent of Next Generation Sequencing (NGS) platforms enables us to probe a limited number of cancer related genes within 2-4 weeks. We have extensively piloted this approach and are now able to deliver clinically meaningful turn-around-times. This development enables us to use this technology to enrich clinical trials using targeted therapies for patients with specific mutations.

We will obtain tumor biopsies of a metastatic or locally advanced lesion and a peripheral blood sample from all patients included in the trial; the biopsies to obtain information on the tumor related genetic mutations (mutational profile) and the blood samples to assess each patient's germline DNA background variation. As patients will be asked to undergo an invasive procedure it is important to address the potential safety issues. Review of the literature and our own experience show that tumor biopsies can be performed with only minor complications and acceptable risks. We will recruit patients with metastatic or locally advanced solid tumors from patients that can potentially be included in clinical trials.

Description:
This is a diagnostic multicenter study combining histological biopsy of tumor material with DNA sequencing using Ion Torrent®, Next Generation Sequencing (NGS) platform. The study aims improve stratification of cancer patients by obtaining fresh tumor biopsies for next-generation sequencing for participation in clinical trials.
