Clinical summary

Summary

This study is the first time a new medicine called AZD9592 is being tested in people. It is an early-phase (Phase I), open-label study, meaning both patients and doctors know which treatment is being given.

The study will take place at several hospitals and will include people with advanced solid tumours.

The study has different parts. Each part will look at how safe AZD9592 is, how well patients can tolerate it, how the drug moves through the body, and how the body reponds to it.

Researchers will also look for early signs that AZD9592 may help shrink or control tumours. AZD9592 will be tested both on its own and together with other cancer treatments. These other treatments will include Osimertinib (in Module 2), and 5-FU, Bevacizumab, Leucovorin (in Module 3).

Conditions

This trial is treating people with advanced solid cancers, including metastatic non-small cell lung cancer with EGFR mutation, head and neck squamous cell carcinoma, or colorectal cancer.
