Spots Global Cancer Trial Database for Patient-derived-organoid (PDO) Guided Versus Conventional Therapy for Advanced Inoperable Abdominal Tumors

Study Description

Brief Summary: Recent studies that ex vivo drug responses on PDO models across different solid tumours can predict treatment responses to chemotherapeutic agents. In patients with metastatic or inoperable solid abdominal tumours, we perform a PDO based drug screen and to identify drugs that will confer clinical response and compared to conventional treatments

Detailed Description: Precision oncology aims to improve the clinical outcomes of patients by offering personalized treatment through identifying druggable genomic aberrations within their tumours. However, current challenges in cancer treatment have hampered the broad clinical utility of the gene-drug associations in the clinic. This is particularly valid when it comes to offering alternative treatment options for advanced inoperable patients with chemo-refractory diseases. There is currently no reliable biomarker to predict treatment response. Patient-derived organoids (PDOs) closely resemble both pheno- and genotypically to patients' tumours. In observational studies, anticancer drug screening ex vivo on PDOs has been shown to predict clinical response with high sensitivity and specificity. PDO-based drug screen represents a truly personalised platform by predicting patient-specific drug response with high accuracy. Recent technical advancements in growing these PDO 'avatars' from biopsies have made it possible to find anticancer drug options in tumours from advanced inoperable patients, and explore new possibilities for treatment options that otherwise would be missed by standard conventional therapies. PDO-based drug assays permit examination of combinatorial drug testing ex vivo and potentially offer patients treatment options. The clinical utility of treatment based on PDO informed drug options however has not been established. We hypothesize that treatment guided by PDO-based drug screens, when compared to conventional treatment, can lead to better treatment response and clinical outcomes. We propose a phase 2 proof-of-concept randomized controlled trial in patients with inoperable or metastatic abdominal tumours refractory to at least one chemotherapeutic agent. Our primary endpoint to this randomised trial is progression-free survival (PFS) at 12 months. In this trial, we in addition expand our current bio-resource of PDOs, and further valid PDO guided treatment model by comparing ex vivo PDO drug response to patients' clinical response.
