Abstract 5938


Once regulatory drug approval is obtained, patients and pharma would greatly benefit from identifying signals of activity in cancer subsets outside the approved indication. In the Netherlands’ precision oncology-network (), Whole Genome Sequencing (WGS) is offered to systemically treated cancer patients. This allows us to identify a spectrum of potentially actionable genetic aberrations in all types of cancer. The DRUP provides patients with such aberrations access to genetically matched treatment upon central review of the tumor profile.


Adult patients with solid tumors, glioblastoma, lymphoma or multiple myeloma, with no standard treatment options, are eligible. Patients are enrolled in multiple parallel cohorts, each defined by 1 tumor type, 1 tumor profile and 1 treatment. Efficacy is analyzed per cohort using a Simon-2-stage approach, aimed at ≥ 1 clinical benefit (CR, PR or SD ≥ 16 weeks)/8 patients in stage I, and ≥5/24 in stage II (85% power, α error rate 7.8%). A fresh tumor biopsy for biomarker research is mandatory. There are currently 23 participating hospitals and 19 study drugs, supplied by 10 pharmaceutical companies.


Since study launch Sep 2016, ∼250 cases were submitted for review and about 1/3 of these patients have started study treatment. Clinical benefit was observed in 37% (6% CR, 14% PR, 17% SD ≥ 16 weeks; all CRs and 2/3 of PRs were ongoing at the time of writing and awaiting ≥30 days confirmation). About 2/3 of case submissions were rejected, due to a general protocol ineligibility (18%), b current unavailability of matching study drugs (17%), c no actionable target detected (15%), d negative evidence for target-drug-match (13%), e eligible for standard treatment (12%), f eligible for competing trials (11%), g loss to follow up (10%) or h genetic tumor profile not yet assessed (4%).


Execution of a national multi-drug and multi-tumor precision oncology trial is feasible. By performing WGS in many different cancer types, subgroups are identified who may benefit from existing drugs outside of their registered indication. This study hereby accelerates translation of new findings to the clinic and increases the yield of existing therapies.
