LYT-200 for Acute Myeloid Leukemia and Preleukemia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial tests the safety and effectiveness of a new treatment called LYT-200 for certain blood cancers. It focuses on individuals with acute myeloid leukemia (AML) or high-risk myelodysplastic syndrome (MDS), particularly if previous treatments failed. The trial consists of two parts: one uses LYT-200 alone, and the other combines it with other cancer drugs. It suits those with AML or high-risk MDS that has returned or not responded to other treatments. As a Phase 1 trial, the research aims to understand 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 information does not specify whether you need to stop taking your current medications. It's best to discuss this with the study team or your doctor.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
Research shows that LYT-200 is being tested for safety and tolerability. In earlier studies, LYT-200 was active and helped control the disease in patients with acute myeloid leukemia (AML), suggesting promise but also the need to consider possible side effects.
So far, 37 patients have tried LYT-200, either alone or with other drugs. This ongoing study closely monitors patient responses. Although still in early stages, the treatment has received fast track status from the FDA, which is given to drugs that might meet unmet medical needs, indicating some confidence in its potential safety.
The complete safety profile will become clearer as more data is gathered. However, early signs suggest that LYT-200 might be well-tolerated by many patients.12345Why do researchers think this study treatment might be promising?
LYT-200 is unique because it targets galectin-9, a protein involved in immune suppression, potentially enhancing the body's ability to fight cancer cells. Most treatments for acute myeloid leukemia (AML) and high-risk myelodysplastic syndromes (MDS) focus on targeting the cancer cells directly, like chemotherapy drugs such as cytarabine and daunorubicin, or on disrupting cancer cell growth pathways like venetoclax does. In contrast, LYT-200 works by potentially altering the tumor microenvironment to improve immune response. Researchers are excited about LYT-200 because this mechanism might offer an innovative way to tackle resistant forms of AML and MDS, providing hope for patients who have relapsed or do not respond well to existing treatments.
What evidence suggests that LYT-200 might be an effective treatment for acute myeloid leukemia and preleukemia?
Research has shown that LYT-200 may help treat acute myeloid leukemia (AML). In this trial, participants may receive LYT-200 as a single agent, which previous studies found effective in stabilizing the disease in patients who had undergone multiple treatments. Another group will receive LYT-200 combined with drugs like venetoclax or azacitidine. Past research demonstrated that such combinations resulted in 80% of patients experiencing stable disease or better, with some achieving complete recovery. Venetoclax, when combined with decitabine or azacitidine, also produced good results in older AML patients. These early findings suggest that LYT-200, whether used alone or with other drugs, could effectively treat AML and similar conditions.36789

Are You a Good Fit for This Trial?
This trial is for adults over 18 with relapsed/refractory Acute Myeloid Leukemia or high-risk Myelodysplastic Syndrome, who've tried at least one treatment without success and have no other beneficial standard treatments available. Participants must be able to perform daily activities with relative ease (ECOG ≤ 2) and meet specific health criteria like a certain white blood cell count and organ function.Inclusion Criteria

What Are the Treatments Tested in This Trial?
Interventions
- LYT-200
Trial Overview
LYT-200, a new potential therapy, is being tested in this Phase 1 trial for safety, how the body processes it (pharmacokinetics), and its effectiveness against AML/MDS. The study involves patients receiving LYT-200 to evaluate these aspects in those with advanced forms of these blood disorders.
