Trial Summary

Will I have to stop taking my current medications?

The trial protocol does not specify if you must stop taking your current medications. However, certain medications like proton pump inhibitors and some chemotherapy drugs must be stopped before registration. It's best to discuss your current medications with the study team to understand any specific requirements.

What data supports the effectiveness of the drug Blinatumomab for treating Acute Lymphoblastic Leukemia?

Blinatumomab has shown effectiveness in treating relapsed or refractory acute lymphoblastic leukemia (ALL), with clinical trials demonstrating higher complete remission rates and improved survival compared to standard chemotherapy. In the TOWER trial, patients receiving Blinatumomab had a 34% complete remission rate compared to 16% with standard chemotherapy, and a median survival of 7.7 months versus 4.0 months.12345

Is the combination of Blinatumomab and chemotherapy safe for treating acute lymphoblastic leukemia?

Blinatumomab, used in treating acute lymphoblastic leukemia, has shown some side effects like cytokine release syndrome (a severe immune reaction) and neurotoxicity (nerve damage), but these can be managed with strategies like premedication and dose adjustments. In trials, it was generally well-tolerated, and patients recovered from severe chemotherapy-related toxicity when treated with Blinatumomab.12567

What makes the drug combination of Blinatumomab and Dasatinib unique for treating acute lymphoblastic leukemia?

This drug combination is unique because it offers a chemotherapy-free option for treating Philadelphia chromosome-positive acute lymphoblastic leukemia, with Blinatumomab engaging the immune system to target cancer cells and Dasatinib inhibiting cancer cell growth. This approach can lead to significant molecular responses with potentially fewer toxicities compared to traditional chemotherapy.12489

What is the purpose of this trial?

This phase II trial studies the side effects and how well blinatumomab and combination chemotherapy or dasatinib, prednisone, and blinatumomab work in treating older patients with acute lymphoblastic leukemia. Immunotherapy with monoclonal antibodies, such as blinatumomab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Chemotherapy drugs, such as prednisone, vincristine sulfate, methotrexate, and mercaptopurine, work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Dasatinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Giving blinatumomab with combination chemotherapy or dasatinib and prednisone may kill more cancer cells.

Eligibility Criteria

This trial is for older patients (65+) with acute lymphoblastic leukemia (ALL), including those with Philadelphia chromosome positive ALL or Ph-like DSMKF. It's suitable for newly diagnosed, relapsed, or refractory cases. Participants must have a certain percentage of lymphoblasts in blood/marrow and be able to provide consent for immunogenicity testing. Exclusions include CNS3 status, Burkitt's leukemia, prior significant treatments for ALL within specific time frames before registration, uncontrolled infections, and other serious health conditions.

Findings from Research

Blinatumomab represents a significant advancement in immunotherapy for relapsed or refractory acute lymphoblastic leukemia (ALL), demonstrating unprecedented efficacy by stimulating a strong T-cell response, which is a departure from traditional chemotherapy.
While blinatumomab offers promising benefits, it also presents unique immunological toxicities and complex administration requirements, necessitating careful consideration of its use compared to other emerging therapies.
Blinatumomab: enlisting serial killer T-cells in the war against hematologic malignancies.Rogala, B., Freyer, CW., Ontiveros, EP., et al.[2023]
Blinatumomab has been approved for treating relapsed or refractory precursor B-cell acute lymphoblastic leukemia (ALL), showing a significant improvement in overall survival and complete remission rates compared to standard chemotherapy, with a median survival of 7.7 months versus 4.0 months for chemotherapy.
In clinical trials, blinatumomab demonstrated a complete remission rate of 34% in Philadelphia chromosome (Ph)-negative ALL and 31% in Ph-positive ALL, while also presenting some adverse events like cytokine release syndrome and neurological issues, although it had fewer cases of neutropenia and infections compared to standard treatments.
FDA Supplemental Approval: Blinatumomab for Treatment of Relapsed and Refractory Precursor B-Cell Acute Lymphoblastic Leukemia.Pulte, ED., Vallejo, J., Przepiorka, D., et al.[2019]
Blinatumomab is a groundbreaking treatment for B-cell precursor relapsed/refractory acute lymphoblastic leukemia (ALL), showing the ability to induce deep remissions in some patients, but many still do not respond or relapse, highlighting the need for improved treatment strategies.
Understanding how patients respond or resist blinatumomab could help identify those who will benefit most, and combining it with other therapies or using it earlier in treatment protocols may enhance its effectiveness and reduce relapse rates.
