Summary

This study is to evaluate the preliminary efficacy and safety of RXC004 monotherapy in advanced solid tumours that have progressed following SoC treatment.

Description

This Phase II, modular, open label, multicentre study will initially open with ring finger protein 43 (RNF43) loss of function (LoF) mutation-positive pancreatic ductal adenocarcinoma (PDAC) (Module 1) and biliary tract cancer (BTC) (Module 2) modules. 15 evaluable patients will be enrolled in each module.

The primary objective of the study is to assess the preliminary efficacy of RXC004 in each module in terms of progression free survival (PFS) at 6 months. Following radiological progression, patients will be followed-up for survival.
