What is the purpose of this trial?

This trial tests the effectiveness of combining two drugs, emavusertib and zanubrutinib, in treating chronic lymphocytic leukemia (CLL). Researchers aim to determine if adding emavusertib can enhance treatment outcomes for individuals already using zanubrutinib. The study includes two groups: one for participants who have had a partial response to zanubrutinib and another for those whose CLL returned after initially responding to the drug. Suitable candidates for this trial are those with CLL who are currently taking zanubrutinib and have either experienced a partial response or a recurrence of CLL. As a Phase 2 trial, this research focuses on assessing the treatment's effectiveness in an initial, smaller group of participants.

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

Research has shown that zanubrutinib is generally easy for people with chronic lymphocytic leukemia (CLL) to tolerate. Studies indicate it is safer compared to similar drugs. For example, patients taking zanubrutinib reported fewer heart-related side effects than those taking ibrutinib, another CLL medication.

When researchers combined emavusertib with ibrutinib (a drug similar to zanubrutinib), patients tolerated it well. This combination was safe for patients with a different type of cancer. Although emavusertib is still under study, these results suggest it might be safe when used with zanubrutinib.

Overall, current evidence suggests that both zanubrutinib and emavusertib are generally well-tolerated. However, since emavusertib is still being researched, some unknown risks may exist.12345

Why are researchers excited about this trial's treatments?

Researchers are excited about Emavusertib and Zanubrutinib for treating chronic lymphocytic leukemia (CLL) because they offer a novel approach compared to standard treatments like chemotherapy and other targeted therapies. Most CLL treatments focus on disrupting cancer cell growth, but Emavusertib is a unique investigational drug that targets specific cancer-related pathways, potentially offering more precise action against cancer cells. Zanubrutinib, a BTK inhibitor, is already known for its effectiveness, and when combined with Emavusertib, it may enhance the overall response in patients. This combination could be particularly beneficial for those who have not responded fully to Zanubrutinib alone, providing a new hope for better outcomes.

What evidence suggests that this trial's treatments could be effective for chronic lymphocytic leukemia?

Research shows that zanubrutinib effectively treats chronic lymphocytic leukemia (CLL), achieving high success rates, particularly in patients new to treatment or those who have relapsed. Additionally, studies on emavusertib, when combined with similar treatments, have shown promising results in shrinking tumors or stabilizing the disease for many patients. Emavusertib targets a protein called IRAK-4, which aids cancer cell survival, thereby improving patient outcomes. In this trial, participants in both Cohort 1 and Cohort 2 will receive a combination of emavusertib and zanubrutinib. This combination may enhance treatment effects, potentially leading to better control of CLL. Early studies suggest this approach could be promising for people with this type of leukemia.16789

Are You a Good Fit for This Trial?

This trial is for adults over 18 with Chronic Lymphocytic Leukemia or other B-cell malignancies. Participants must have been on zanubrutinib for at least a year, have a life expectancy of more than 3 months, and be able to perform daily activities with minimal assistance. They should also have measurable disease but may not join if they still have standard treatment options available.
