Combination Chemotherapy for Acute Lymphoblastic Leukemia
What You Need to Know Before You Apply
What is the purpose of this trial?
This trial explores how well a mix of chemotherapy drugs can treat certain blood cancers, such as acute lymphoblastic leukemia, that have returned or resisted treatment. The combination includes drugs like clofarabine and bortezomib, which aim to stop cancer cells by either killing them or preventing their spread. Suitable candidates for this trial have a type of leukemia or lymphoma that has returned or hasn't responded to past treatments. Participants should have completed their last round of chemotherapy at least 21 days ago. As a Phase 2 trial, this research focuses on measuring the treatment's effectiveness in an initial, smaller group, offering participants a chance to contribute to important findings.
Will I have to stop taking my current medications?
The trial protocol does not specify if you need to stop taking your current medications, but it does allow hydroxyurea and dexamethasone up to 24 hours before starting the trial. If you are taking a tyrosine kinase inhibitor for Philadelphia positive ALL, you do not need to stop it.
Is there any evidence suggesting that this trial's treatments are likely to be safe?
A previous study found clofarabine to be safe and effective for children and young adults with relapsed or hard-to-treat acute lymphoblastic leukemia (ALL), supporting its use in this trial. Cyclophosphamide, another drug in the combination, has treated ALL but can cause serious side effects like infections or bladder problems, so doctors closely monitor patients during treatment.
Research has shown that bortezomib can cause side effects like nerve damage and low blood cell counts. Its safety for children with relapsed ALL isn't fully known, but it has been used in adults. Etoposide can also lower blood cell counts, which doctors watch carefully.
Dexamethasone is commonly used to treat ALL, but it can lead to infections and mood changes. Lastly, vincristine sulfate liposome, a new version of vincristine, is approved for adults with relapsed ALL and is believed to be easier to tolerate.
All these treatments have been studied, and while they may cause side effects, doctors are aware of them and manage them carefully.12345Why are researchers excited about this trial's treatments?
Researchers are excited about this combination chemotherapy treatment for acute lymphoblastic leukemia (ALL) because it integrates several potent drugs, some of which have unique mechanisms of action. Unlike standard treatments, which often focus on a limited number of drugs, this combination includes bortezomib, a proteasome inhibitor that disrupts cancer cell regulation, and clofarabine, which targets DNA replication to halt cancer growth. Additionally, vincristine sulfate liposome offers targeted delivery, potentially reducing side effects while maximizing effectiveness. This comprehensive approach aims to improve outcomes by attacking leukemia cells from multiple angles, offering hope for faster and more effective results compared to traditional therapies.
What evidence suggests that this trial's combination chemotherapy could be effective for acute lymphoblastic leukemia?
Research has shown that the combination of chemotherapy drugs used in this trial holds promise for treating certain types of leukemia and lymphoma. Participants will receive a regimen that includes bortezomib, which has led to remission in many patients, with some studies showing remission rates of up to 44%. Clofarabine, another component of the regimen, helps eliminate small amounts of remaining cancer, enhancing the treatment's effectiveness. Cyclophosphamide and etoposide, also included in the trial, have improved survival rates, with etoposide achieving up to a 43% complete remission rate in some patients. Dexamethasone plays a crucial role in reducing relapse rates, especially in children. Vincristine sulfate liposome, a new version of vincristine used in this trial, improves drug delivery and has shown positive results, particularly in patients who have undergone many previous treatments.678910
