This clinical trial is focused on studying the effects of a new treatment called LSTA1 in combination with standard care for patients with advanced solid tumors, specifically head and neck cancer and cholangiocarcinoma, which is a type of bile duct cancer. The study aims to evaluate the safety of adding LSTA1 to the usual treatments compared to using the usual treatments alone. The usual treatments, also known as standard of care, may include medications like gemcitabine, durvalumab, cisplatin, and paclitaxel, which are commonly used in chemotherapy.
Participants in the study will be randomly assigned to receive either the new treatment with LSTA1 or a placebo, along with their standard care. The study will be conducted over a period of up to 52 weeks, during which participants will receive their assigned treatments through intravenous infusions. The study will monitor the incidence and severity of any side effects, as well as other outcomes such as overall survival, progression-free survival, and response to the treatment.
The goal of this research is to determine if the addition of LSTA1 can improve the outcomes for patients with these types of cancers. By participating in this study, researchers hope to gather valuable information that could lead to better treatment options in the future. The study is designed to be double-blind, meaning neither the participants nor the researchers will know who is receiving the new treatment or the placebo, to ensure unbiased results.
