What is the purpose of this trial?

This trial aims to assess the safety of combining two treatments, sonrotoclax (a new potential drug) and zanubrutinib, for people with certain blood cancers. It will explore different schedules for administering these medications to find the safest approach. Good candidates for this trial include those with chronic lymphocytic leukemia (CLL) who require treatment due to specific disease features and have at least one measurable lesion from scans.

As a Phase 1 trial, participants will be among the first to receive this new treatment combination, aiding researchers in understanding its effects in people.

Do I need to stop my current medications to join the trial?

The trial information does not specify whether you need to stop taking your current medications. However, since prior systemic treatment for CLL is an exclusion criterion, it might be necessary to stop certain treatments. Please consult with the trial coordinators for specific guidance.

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

Research shows that the combination of sonrotoclax and zanubrutinib is generally well-tolerated by patients with certain blood cancers. Earlier studies revealed that most patients could handle this combination's safety profile without severe side effects. Specifically, patients with relapsed or refractory chronic lymphocytic leukemia (R/R CLL) found the treatment manageable at all tested doses.

Zanubrutinib, a component of this treatment, is known for causing fewer serious side effects, particularly those affecting the heart, compared to similar drugs.

For those considering joining a trial, these findings help set expectations about safety. However, each person may react differently, and ongoing studies aim to determine the best dosages for optimal results. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatments?

Unlike the standard treatments for blood cancers, which often include chemotherapy and immunotherapy, sonrotoclax and zanubrutinib offer a novel approach by targeting specific proteins involved in cancer cell survival and growth. Sonrotoclax works by inhibiting a protein called BCL-2, which helps cancer cells avoid death, while zanubrutinib blocks BTK, a key player in cancer cell signaling. Researchers are excited about this combination because it simultaneously disrupts two critical pathways that cancer cells rely on, potentially leading to more effective and durable responses in patients. This dual-targeted strategy could offer a more precise and potent attack against blood cancers, reducing the likelihood of resistance and improving patient outcomes.

What evidence suggests that this trial's treatments could be effective for blood cancers?

Research has shown that the combination of sonrotoclax and zanubrutinib holds promise for treating blood cancers such as chronic lymphocytic leukemia (CLL). In this trial, participants will first receive zanubrutinib monotherapy, followed by the combination with sonrotoclax. Sonrotoclax blocks a protein called Bcl-2, which aids cancer cell growth. This action can slow or halt cancer growth and promote cell death. Studies have found that this combination is effective and has fewer side effects compared to older treatments like ibrutinib and venetoclax. Early results also suggest high overall response rates (ORR) in patients, indicating that many experience tumor shrinkage or disappearance. ^{2 3 4 6 7}

What Are the Treatments Tested in This Trial?

Interventions

• Sonrotoclax

Trial Overview The study tests new dosing schedules for a drug called Sonrotoclax in patients with blood cancers, alongside another drug named Zanubrutinib. The goal is to find out how safe these novel dose ramp-up schedules are when starting Sonrotoclax treatment.

How Is the Trial Designed?

Group I: Part 2: Schedule Expansion Experimental Treatment 2 Interventions

Participants will receive zanubrutinib monotherapy with fixed duration, followed by combination sonrotoclax with zanubrutinib at ramp-up schedules as determined in Part 1.

Group II: Part 1: Schedule Calibration Experimental Treatment 2 Interventions

Participants will receive zanubrutinib monotherapy with fixed duration, followed by combination sonrotoclax with zanubrutinib at protocol-defined ramp-up schedules until target daily dose will be reached.

Published Research Related to This Trial

In a study comparing treatment regimens for relapsed/refractory acute myeloid leukemia (R/R AML), the venetoclax (VEN) combination therapy showed a comparable overall response rate (59.3%) to intensive chemotherapy (IC) (44.0%), suggesting it is an effective alternative for patients who have failed previous treatments.

Patients receiving the VEN combination had a significantly higher percentage of successful stem cell transplants at blast clearance (86.5% vs. 62.3% for IC), indicating better disease control and potentially lower treatment-related mortality.

In patients with newly diagnosed unfit acute myeloid leukemia (AML), the combination of azacitidine and venetoclax is a standard first-line treatment.

However, patients with TP53-mutated AML and poor-risk cytogenetics do not benefit from adding venetoclax to azacitidine, suggesting that alternative treatment regimens should be considered for these individuals.

In a phase 2 trial involving 39 patients with treatment-naive chronic lymphocytic leukaemia or small lymphocytic lymphoma, the combination therapy of zanubrutinib, obinutuzumab, and venetoclax (BOVen) achieved an impressive 89% rate of undetectable minimal residual disease (MRD) in both blood and bone marrow after a median treatment duration of 10 months.

The BOVen regimen was well tolerated, with the most common side effects being thrombocytopenia and neutropenia, and it supports the idea of using MRD as a biomarker to guide treatment duration, potentially allowing for earlier therapy discontinuation.

In a study of 79 patients with acute myeloid leukemia (AML), the venetoclax-based regimen achieved a high overall response rate of 64.6%, with a significantly higher complete remission rate in newly diagnosed unfit AML patients compared to those with relapsed/refractory AML (60.5% vs 27.8%).

The median overall survival for unfit AML patients was notably longer at 14.1 months, especially for those with NPM1 or IDH1/2 mutations, while the regimen was found to be tolerable despite a high incidence of adverse effects, primarily infections.

In a pooled analysis of treatment-naïve patients with FLT3-mutant acute myeloid leukemia, the combination of venetoclax and azacitidine resulted in a significantly higher composite complete remission rate (67%) compared to azacitidine alone (36%), with a median overall survival of 12.5 months versus 8.6 months.

The treatment was found to be safe, with no unexpected toxicities reported, indicating that venetoclax + azacitidine is a promising option for older patients or those with comorbidities who are ineligible for intensive therapy.

Zanubrutinib has been approved for treating various lymphoproliferative disorders, providing a significant option for patients who have not responded to standard therapies.

A panel of experts identified unmet clinical needs in the use of zanubrutinib for specific lymphomas, such as Waldenström macroglobulinemia, and made recommendations for future studies to optimize its use, especially for less experienced healthcare providers.

The development of a drug combination nanoparticle (DcNP) formulation, VZ-DcNP, allows for synchronized delivery of venetoclax and zanubrutinib, enhancing their uptake in leukemic cells by threefold compared to free drugs.

VZ-DcNP significantly extends the half-lives of venetoclax and zanubrutinib in mice, by approximately 43-fold and 5-fold respectively, suggesting improved therapeutic potential for sustained leukemia treatment.

The combination of venetoclax (Ven) and azacitidine (AZA) shows a high efficacy in treating acute myeloid leukemia (AML) and myelodysplastic syndrome (MDS), with an overall complete response rate of 57.9% across 19 studies involving 1615 patients.

This treatment is particularly effective for newly diagnosed AML patients, achieving a complete response rate of 67.5%, although it is less effective for those with relapsed or refractory AML, which had a response rate of only 30%.
