TL-895 is a medication being tested in this clinical trial. It is designed to help people with certain types of blood cancers, specifically B-cell malignancies. These are cancers that affect a type of white blood cell called B-cells, which are part of the immune system. The trial is looking at how well TL-895 works on its own for people whose cancer has come back or hasn’t responded to other treatments. The goal is to see if TL-895 can help reduce the cancer or stop it from growing.

Navtemadlin is another medication being studied in this trial. It is being tested in combination with TL-895 for people with a type of blood cancer called Chronic Lymphocytic Leukemia (CLL) or Small Lymphocytic Lymphoma (SLL). These are slow-growing cancers that affect the lymphocytes, another type of white blood cell. The trial aims to find out if using Navtemadlin together with TL-895 can improve treatment outcomes for patients who are either newly diagnosed or have had their cancer return after previous treatments. The researchers want to see if this combination can help control the cancer more effectively.

B Cell Malignancies – B cell malignancies are a group of cancers that affect B lymphocytes, which are a type of white blood cell responsible for producing antibodies. These malignancies can include various types of lymphomas and leukemias. The disease often begins with the abnormal growth of B cells, leading to their accumulation in the lymph nodes, blood, or other tissues. As the disease progresses, it can cause symptoms such as swollen lymph nodes, fatigue, fever, and weight loss. The progression can vary depending on the specific type of B cell malignancy. Over time, the abnormal B cells can interfere with normal blood cell production and immune function.

Chronic Lymphocytic Leukemia – Chronic Lymphocytic Leukemia (CLL) is a type of cancer that affects the blood and bone marrow, characterized by the slow accumulation of abnormal lymphocytes, a type of white blood cell. It typically progresses slowly and may not cause symptoms for years. As the disease advances, it can lead to symptoms such as swollen lymph nodes, fatigue, fever, and weight loss. The abnormal lymphocytes can crowd out healthy blood cells, leading to anemia, infections, and bleeding problems. CLL often affects older adults and is the most common type of leukemia in this age group. The progression of CLL can vary widely among individuals.

Small Lymphocytic Lymphoma – Small Lymphocytic Lymphoma (SLL) is a type of non-Hodgkin lymphoma that is closely related to Chronic Lymphocytic Leukemia (CLL), involving the same type of cancerous B lymphocytes. Unlike CLL, which primarily affects the blood and bone marrow, SLL mainly involves the lymph nodes. The disease progresses slowly and may not cause symptoms initially. As it advances, it can lead to swollen lymph nodes, fatigue, fever, and weight loss. The abnormal B cells can accumulate in the lymph nodes and other organs, potentially affecting their function. SLL and CLL are considered different manifestations of the same disease.
