E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To determine the intratumoral concentration of osimertinib in peritoneal metastasis upon 2 weeks of treatment of patients who are candidate for CRS-HIPEC treatment (group 1), and in liver metastasis of patients who are candidate for primary liver resection (group 2). These clinical determined intratumoral osimertinib concentrations will be compared with the effective tissue concentrations in PDTOs from PM of CRC from the PDO-CRPM study. |
|
E.2.2 | Secondary objectives of the trial |
• To assess inter- and intrapatient variability in intratumoral osimertinib concentrations • To measure osimertinib concentration in ascites (if present at surgery) and plasma • Correlation between plasma, ascites, healthy tissue and intratumoral concentration • To determine differences in intratumoral TKI concentrations between PM and liver metastasis • To assess the safety and tolerability of pre-operative osimertinib treatment for 2 weeks in patients who will undergo CRS-HIPEC for PM of CRC (group 1) and in patients who will undergo primary liver resection or liver metastasis of CRC (group 2)
|
