Promising colorectal cancer study pulled before it even started
NCT ID NCT07323576
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study aimed to see if adding the targeted drug inavolisib to standard chemotherapy and bevacizumab could help people with a specific genetic form of advanced colorectal cancer (PIK3CA-mutated). It was designed for adults who had not yet received treatment for metastatic disease. However, the study was withdrawn before enrolling any participants, so no results are available.
