Ipilimumab + DLI for Leukemia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the safety of ipilimumab in patients with certain blood cancers, such as Acute Myeloid Leukemia (AML) and Myelodysplastic Syndromes (MDS). The researchers aim to determine the highest safe dose while monitoring for side effects. Participants will receive ipilimumab along with donor lymphocyte infusion (DLI), which involves returning specific immune cells to the patient. This trial may suit individuals who have relapsed at least two months after a stem cell transplant and still have their original stem cell donor available. As a Phase 1 trial, the research focuses on understanding how the treatment works in people, offering participants the chance to be among the first to receive this new treatment.
Will I have to stop taking my current medications?
The trial requires that you stop taking certain medications, such as systemic corticosteroids and other treatments for GVHD, at least 4 weeks before participating. If you are on anti-tumor chemotherapy, investigational agents, or immunotherapy, you must also stop these before joining the trial.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research has shown that ipilimumab is often used to treat cancer, but it can cause immune-related side effects, such as diarrhea, skin rash, and liver inflammation. This study examines the safety of using ipilimumab with a specific cell therapy called CD25hi Treg-depleted DLI.
As a Phase 1 trial, the primary goal is to determine the safe dosage and identify any side effects in individuals with certain blood cancers, like Acute Myeloid Leukemia (AML). The treatment is still in the early stages of safety testing in humans. Detailed information about side effects from this specific study is not yet available, but the focus remains on ensuring the treatment's safety.12345Why do researchers think this study treatment might be promising for leukemia?
Unlike the standard leukemia treatments, which typically involve chemotherapy and radiation, the combination of Ipilimumab with DLI offers a unique approach by utilizing the immune system to fight cancer. Ipilimumab is a checkpoint inhibitor that helps activate the immune system's T-cells to recognize and attack cancer cells, a mechanism different from traditional methods that directly target cancer cells. Additionally, the use of CD25hi Treg-depleted DLI is designed to enhance this immune response further by reducing regulatory T-cells that can suppress the immune attack on cancer. Researchers are excited about this treatment because it represents a novel immunotherapy approach that could offer improved effectiveness with potentially fewer side effects compared to conventional therapies.
What evidence suggests that this trial's treatments could be effective for leukemia?
In this trial, participants will receive a combination of ipilimumab and a special type of cell therapy called Treg-depleted DLI. Research on this combination shows promise for treating blood cancers like leukemia. Previous studies have demonstrated that this combination can enhance the immune system's ability to attack cancer cells, a response known as the "graft-versus-leukemia" effect. This treatment has generally been tolerable for patients, though risks exist, such as graft-versus-host disease, where immune cells might attack the body. The main focus has been on ensuring safety and determining the right dose, but early results are encouraging for those whose cancer has returned after treatments like stem cell transplants.12367
