Debio 1347-101 Phase I Trial in Advanced Solid Tumours With Fibroblast Growth Factor Receptor (FGFR) Alterations

A Phase I, Gene Alteration-based, Open Label, Multicenter Study of Oral Debio 1347 (CH5183284) in Patients With Advanced Solid Malignancies, Whose Tumours Have an Alteration of the FGFR 1, 2 or 3 Genes

This study is primarily designed to assess the safety and the tolerability of Debio1347 (CH5183284) in patients with advanced solid malignancies, whose tumours have an alteration of the Fibroblast Growth Factor Receptor (FGFR) 1, 2 or 3 genes, for whom standard treatment does not exist or is not indicated.

The main objective of Part A is to identify the dose-limiting toxicities (DLTs) and estimate the maximum tolerated dose (MTD) based on the safety and tolerability of Debio1347 orally administered daily to these patients, in order to determine the recommended dose.

The main objective of Part B is to evaluate the safety profile at the recommended dose, in a larger cohort of these patients.
