What You Need to Know Before You Apply

What is the purpose of this trial?

This trial tests the effectiveness of different treatment combinations for older patients with acute lymphoblastic leukemia (ALL), a type of blood cancer. It examines two main treatments: blinatumomab, an immunotherapy that aids the immune system in fighting cancer, and dasatinib, which inhibits cancer cell growth. Participants will receive these treatments alongside standard chemotherapy drugs to determine which combination is most effective in killing cancer cells and to monitor side effects. Eligible participants have been diagnosed with ALL and have not received certain prior treatments. As a Phase 2 trial, the research focuses on assessing the treatment's effectiveness in an initial, smaller group of people.

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.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that blinatumomab is generally well-tolerated for treating acute lymphoblastic leukemia. In real-world use, serious side effects occurred in about 12.5% of patients, indicating that most people manage it well. This medication helps the body's immune system fight cancer cells.

Dasatinib, also part of this trial, works by blocking enzymes that promote cancer growth. The FDA has approved it for other conditions, indicating its safety for humans. While specific side effect data is not provided here, its approval suggests it is usually safe with careful monitoring.

Overall, these treatments have shown promise with a safety profile that most people can handle well, though monitoring for side effects remains important. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Researchers are excited about these treatments for Acute Lymphoblastic Leukemia (ALL) because they combine innovative therapies with traditional chemotherapy methods to enhance effectiveness. Blinatumomab is an immunotherapy that uniquely targets specific proteins on cancer cells, potentially improving the immune system's ability to attack leukemia cells more precisely. Dasatinib, on the other hand, is a targeted therapy that blocks certain enzymes involved in cancer cell growth, offering a more focused approach compared to conventional chemotherapy. Together, these treatments aim to provide a more comprehensive attack on leukemia cells, potentially leading to better outcomes for patients.

What evidence suggests that this trial's treatments could be effective for acute lymphoblastic leukemia?

Research has shown that blinatumomab effectively treats certain types of acute lymphoblastic leukemia (ALL). One study found that 78% of patients achieved MRD (minimal residual disease) negativity, meaning no detectable cancer cells remained after treatment. In this trial, participants in Cohort I will receive blinatumomab with POMP chemotherapy, while those in Cohort II will receive dasatinib, prednisone, and blinatumomab. Dasatinib blocks enzymes that help cancer cells grow, potentially preventing leukemia from spreading. Both treatments have shown promise in improving patient outcomes. This combination aims to boost the immune system to fight cancer and halt cancer cell growth, offering a comprehensive approach to tackling ALL. ^{5 6 7 8 9}

Trial Overview

The trial tests blinatumomab combined with chemotherapy drugs like prednisone and vincristine versus dasatinib plus prednisone and blinatumomab in treating older adults with ALL.

Published Research Related to This Trial

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 promising new treatment for adults with relapsed or refractory B-cell acute lymphoblastic leukemia, showing effectiveness in targeting and destroying tumor cells by engaging both T-cells and B-cells.

While there are potential side effects like immunological toxicities and cytokine release syndrome, most patients tolerate blinatumomab well, indicating a favorable safety profile compared to traditional therapies.

Clinical use of blinatumomab for B-cell acute lymphoblastic leukemia in adults. Lee, KJ., Chow, V., Weissman, A., et al.[2022]

Blinatumomab, a bispecific T-cell-engaging antibody, has shown a response rate of 34% to 66% in heavily pretreated children with relapsed/refractory acute lymphoblastic leukemia (R/R-ALL), making it a promising treatment option, especially as a bridge to stem cell transplantation.

Recent randomized controlled trials indicate that blinatumomab leads to a greater reduction in minimal residual disease and improved survival compared to standard treatments, suggesting its potential for frontline use in high-risk patients.

Blinatumomab: Bridging the Gap in Adult Relapsed/Refractory B-Cell Acute Lymphoblastic Leukemia. Folan, SA., Rexwinkle, A., Autry, J., et al.[2018]

In a phase 3 clinical trial involving 669 patients aged 1 to 30 years with first relapse of B-cell acute lymphoblastic leukemia (B-ALL), substituting blinatumomab for intensive chemotherapy in consolidation therapy showed a 2-year disease-free survival rate of 54.4% compared to 39.0% for the chemotherapy group, suggesting a potential benefit of blinatumomab in this high-risk population.

Blinatumomab also demonstrated a better safety profile, with significantly lower rates of serious adverse events such as infections and febrile neutropenia compared to traditional chemotherapy, indicating it may be a safer option for treating relapsed B-ALL.

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 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.
