What side effects are associated with this type of intervention?

Common treatments for Acute Myeloid Leukemia (AML) often involve chemotherapy, monoclonal antibodies, and radiation therapy. Chemotherapy drugs like fludarabine and melphalan can cause side effects such as leukopenia, thrombocytopenia, anemia, infections, and increased transaminases. Monoclonal antibodies targeting specific cancer cells may lead to infusion reactions, fatigue, and immunosuppression. Total marrow and lymphoid irradiation (TMLI) can result in side effects like nausea, fatigue, and increased risk of infections. Combining these treatments aims to improve outcomes but also increases the potential for cumulative side effects.

What prior FDA approvals exist?

The FDA has approved several treatments for Acute Myeloid Leukemia (AML), including monoclonal antibodies and targeted therapies. For instance, gemtuzumab ozogamicin, an antibody-drug conjugate targeting CD33, has been approved for newly diagnosed and relapsed AML. Additionally, hypomethylating agents like azacitidine and decitabine are commonly used for AML treatment. While specific FDA approvals for treatments exactly like 90Y-DOTA-anti-CD25 basiliximab are not detailed, the use of monoclonal antibodies and targeted therapies in AML is well-established.

What other types of research exist?

Promising novel alternatives for AML treatment include: 1) Actinium-225-lintuzumab, an anti-CD33 antibody conjugated to actinium-225, which has shown safety and biological activity in early trials. 2) Venetoclax combined with hypomethylating agents (HMAs) like azacitidine or decitabine, which has demonstrated improved outcomes in AML patients. 3) IDH inhibitors such as ivosidenib for IDH1-mutated AML, which can induce durable remissions. 4) FLT3 inhibitors like gilteritinib, especially in combination with HMAs, which have shown higher overall response rates. These alternatives represent targeted and combination therapies that are currently under investigation or have shown promising results in clinical trials.

Summary

This trial tests a combination of a special antibody with radiation, chemotherapy, and targeted radiation therapy. It is aimed at patients with high-risk leukemia or myelodysplastic syndrome who can't have standard treatments. The treatment targets cancer cells directly and prepares the body for a stem cell transplant.

Who is the study for?

This trial is for adults with high-risk acute leukemia or myelodysplastic syndrome who are not candidates for intensive treatment due to age or comorbidities. Participants must have CD25 positive cancer cells, adequate organ function, and agree to birth control measures. Those with more than three prior treatments, uncontrolled infections, recent intensive therapies, or unable to comply with study procedures are excluded.

What is being tested?

The trial tests a combination of the radioactive antibody 90Y-DOTA-anti-CD25 basiliximab with chemotherapy drugs fludarabine and melphalan, plus total marrow and lymphoid irradiation (TMLI). It aims to determine the best dose and assess potential benefits and side effects in preparation for stem cell transplantation.

What are the potential side effects?

Potential side effects include reactions related to radiation exposure such as fatigue and nausea; immune responses from the monoclonal antibody; complications from chemotherapy like low blood counts leading to infection risk; organ inflammation; allergic reactions; and infertility risks.

Mechanism Of Action

Prior Approvals

Other Research

Common treatments for Acute Myeloid Leukemia (AML) include chemotherapy, targeted therapy, and monoclonal antibodies. Chemotherapy drugs like fludarabine and melphalan work by damaging the DNA of rapidly dividing cells, leading to cell death. Targeted therapies, such as those inhibiting specific mutations (e.g., FLT3 inhibitors), block the signaling pathways that promote cancer cell growth. Monoclonal antibodies, like 90Y-DOTA-anti-CD25 basiliximab, specifically target cancer cells expressing certain markers (e.g., CD25) and deliver cytotoxic agents directly to them, minimizing damage to healthy cells. These mechanisms are crucial for AML patients as they offer more precise and effective treatment options, potentially improving outcomes and reducing side effects.
