Brief Summary
Pharmacoscopy refers to an ex vivo real-time drug sensitivity profiling platform that has been shown to be of value in the treatment of leukemia (Snijder et al. 2017) (Kornauth et al. 2022) and may help to identify novel treatment opportunities for brain tumors as well (Lee et al. 2022). The rationale for pharmacoscopy-based drug sensitivity testing on real-time patient biopsies or surgery material is multiple: measuring drug response and sensitivity directly in real-time patient material, overcomes the problem of limited molecular biomarkers for established targeted therapeutic options and can identify effective drugs even for non-targeted therapies such as chemotherapy. It can also identify hitherto unknown specific vulnerabilities of cancer cells. Furthermore, testing directly on patient material overcomes the limitations of patient-derived cell cultures, organoids, and patient xenografts, as their prolonged culture times risk cellular adaptations and clonal selection that alter drug sensitivity. Pharmacoscopy maintains the tumor cell composition, including bystander cells or tumor microenvironment, and limits cell culture to max 48 hours. Furthermore, pharmacoscopy measures drug responses on a single-cell and on a high-content level, uniquely allowing to measure the drug sensitivity of tumor cells, and allowing to compare it to the drug cytotoxicity on healthy cells from the same patient. This relative readout has previously been shown to be essential for the correct prediction of a clinical response in haematological malignancies (Snijder et al. 2017) (Kornauth et al. 2022). The aim of this study is to generate preliminary data regarding superiority of the personalized pharmacoscopy-guided approach compared to a standard non-pharmacoscopy-guided approach, in patients with brain metastases with an indication for surgery, and limited therapeutic systemic options according to the treating physician.
Eligibility Criteria
Inclusion Criteria: * Patients must be 18 years or older on the day of signing the informed consent, female or male. * Patients must have a Karnofsky performance status of 60 or more * Patients must have limited systemic therapeutic options as per treating physician judgement. The number of previous lines of therapies is not limited. * Patients with a tumor with a targetable oncogenic driver mutation should have already been treated with a targeted agent and options must have been exhausted. * Patients must have a clinical indication for surgery for probable brain metastasis * Patients will be considered eligible for the study only if the diagnosis of brain metastasis has been histologically confirmed on the sample obtained during the surgery performed after signing the informed consent form for the trial. * Any type of primary cancer is allowed: breast cancer, lung cancer, melanoma, other cancers. Patients may have several primary cancers. * Patients must have adequate bone marrow, renal and hepatic function documented at screening before surgery * Women of childbearing potential, including women who had their last menstruation in the last 2 years, must have a negative urinary or serum pregnancy test * Patients must have the ability to understand the requirements of the study, provide written informed consent and authorization of use and disclosure of protected health information, and agree to abide by the study restrictions and return for the required assessments. * Written informed consent for study participation must be signed and dated by the patient and the investigator prior to any study-related intervention. Exclusion Criteria: * Patients with rapidly progressive systemic disease * Patients with inability to undergo brain MRI evaluation. * Patients with progressive parenchymal brain metastases with an indication for requiring whole brain radiotherapy after surgery. Focal brain radiotherapy after surgery is allowed. * Judgement by the investigator that the patient is unlikely to comply with study procedures, restrictions and requirements. * Intention to become pregnant during the course of the study. * Female who are pregnant. * Female who are breastfeeding and who do not agree to discontinue nursing prior to the first treatment initiated during the study. * Sexually active males and females of childbearing potential who are not willing to use an effective contraceptive method during the study. Male participants who do not agree not to donate sperm.
