This clinical trial is focused on studying patients with cancer that has spread to the brain, known as brain metastasis. The trial will use a special treatment called 68Ga-NOTA-anti-HER2 VHH1, which is a solution for injection. This treatment is designed to help doctors see how well it targets cancer cells in the brain. The purpose of the study is to compare how this treatment is taken up in brain metastasis lesions in patients who have HER2-positive cancer and those who do not.
During the study, patients will receive the 68Ga-NOTA-anti-HER2 VHH1 injection through a vein, a method known as intravenous administration. The study will observe how the treatment is absorbed by the cancer cells in the brain. This will be done by a nuclear medicine doctor who will look at images to see if the treatment is working. The doctor will not know the HER2 status of the patients to ensure unbiased results. The study will also measure the uptake of the treatment using a method called Standard Uptake Values (SUV), which helps to quantify how much of the treatment is absorbed by the cancer cells.
If possible, the study will also look at how the uptake of the treatment changes during and after any other treatments the patients might be receiving. This information will be compared to the patients’ overall disease progression. The study aims to provide valuable insights into the effectiveness of 68Ga-NOTA-anti-HER2 VHH1 in targeting brain metastasis in cancer patients, potentially leading to better treatment options in the future.
