This clinical trial is focused on studying treatments for advanced solid tumors, which are types of cancer that have spread beyond their original location. The study will explore the effects of a new medication called AZD5305, which is taken as a film-coated tablet. This medication will be tested both on its own and in combination with other anti-cancer drugs. The purpose of the study is to assess the safety and tolerability of AZD5305 in patients with advanced cancer.
Participants in the study will receive AZD5305 either alone or alongside other treatments such as DS-8201a (also known as trastuzumab deruxtecan), camizestrant, and datopotamab deruxtecan. These additional treatments are designed to target specific proteins in cancer cells, potentially enhancing the effectiveness of the therapy. Some patients may also receive a placebo as part of the study. The study will involve regular monitoring to ensure the safety of participants and to gather information on how the body processes these medications.
The trial will take place over several years, with participants undergoing various assessments to monitor their health and the impact of the treatments. These assessments will include physical examinations and laboratory tests to track any changes in the body. The study aims to provide valuable insights into the potential benefits and risks of using AZD5305 and its combinations in treating advanced solid tumors.
