This clinical trial is focused on studying a new treatment for certain types of cancer known as epithelial solid tumors. These are cancers that start in the cells that line the surfaces of organs and tissues in the body. The treatment being tested is called ATTR-01, which is a special type of medicine designed to target and attack cancer cells. It is given to patients through an injection into a vein, known as an intravenous method.
The purpose of the study is to understand how safe and tolerable ATTR-01 is for patients with these types of cancers. The study will also look at how well the treatment works in shrinking or controlling the tumors. ATTR-01 is a genetically modified virus that specifically targets cancer cells that have a certain protein on their surface. Once inside the cancer cells, it helps the body’s immune system to fight the cancer by producing a cancer-fighting antibody called atezolizumab.
Participants in the study will receive either the ATTR-01 treatment or a placebo. The study will be conducted in different phases to determine the best dose of the treatment and to monitor its effects over time. Patients will be closely observed for any side effects and to see how their cancer responds to the treatment. The study aims to provide valuable information that could lead to new treatment options for people with these types of cancers in the future.
