What is the purpose of this trial?

This trial tests a new treatment called BGB-16673 for various B-cell cancers, which are blood cancers affecting B-cells. Researchers aim to determine the best dose and assess the safety and effectiveness of this treatment in individuals with certain B-cell cancers that have recurred or resisted treatment. Participants must have a confirmed diagnosis of specific B-cell cancers, such as chronic lymphocytic leukemia or mantle cell lymphoma, and have experienced recurrence or resistance to previous treatments. As a Phase 1 trial, this research focuses on understanding how the treatment works in people, offering participants the opportunity to be among the first to receive it.

Will I have to stop taking my current medications?

The trial information does not specify if you need to stop taking your current medications. However, it mentions that ongoing systemic corticosteroid treatment is an exclusion criterion, which might imply some restrictions. It's best to discuss your specific medications with the trial coordinators.

Is there any evidence suggesting that BGB-16673 is likely to be safe for humans?

Research has shown that BGB-16673 is generally well-tolerated by patients with B-cell cancers. Studies involving patients with relapsed or hard-to-treat chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) have demonstrated promising safety results. Most side effects were mild to moderate, with tiredness and diarrhea being common.

Another study involved patients with mantle cell lymphoma (MCL) and marginal zone lymphoma (MZL) taking BGB-16673. Most experienced manageable side effects, and the treatment was well-tolerated even at higher doses.

Overall, while some side effects are expected, evidence so far indicates that BGB-16673 is safe enough for continued testing in clinical trials. Prospective participants should discuss with a doctor to understand all potential risks and benefits before joining a trial. ^{1 2 3 4 5}

Why do researchers think this study treatment might be promising for B-cell cancers?

Researchers are excited about BGB-16673 because it offers a novel approach to treating B-cell cancers. Unlike current treatments that often target the B-cell receptor or use chemotherapy, BGB-16673 is designed to inhibit Bruton's tyrosine kinase (BTK), a key player in B-cell malignancy pathways, with the potential to improve efficacy and safety profiles. This could mean fewer side effects and better outcomes for patients who have relapsed or are resistant to traditional treatments. Furthermore, BGB-16673 might offer new hope for patients who haven't responded to or cannot tolerate existing BTK inhibitors, making it a promising option in the fight against these challenging cancers.

What evidence suggests that BGB-16673 might be an effective treatment for B-cell cancers?

Research has shown that BGB-16673 holds promise for treating B-cell cancers. Studies have found it safe, well-tolerated, and effective in fighting tumors. Notably, nearly 85% of patients with relapsed or hard-to-treat chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL) responded to treatment. In this trial, participants will receive BGB-16673 to evaluate its safety and efficacy across various B-cell cancers, including mantle cell lymphoma and marginal zone lymphoma. BGB-16673 targets a protein that aids cancer cell growth, potentially slowing or stopping their spread. This makes it a hopeful option for people with these conditions. ^{2 5 6 7 8}

Ibrutinib, a BTK inhibitor, has demonstrated excellent efficacy in treating chronic lymphocytic leukemia/small lymphocytic lymphoma (CLL/SLL) across various patient groups, including treatment-naïve and high-risk individuals.

As the use of ibrutinib increases, concerns about adverse events and drug resistance have arisen, leading to the exploration of new therapeutic targets and promising novel agents in early development to address these challenges.

Zanubrutinib, a Bruton's tyrosine kinase inhibitor, is primarily metabolized by the CYP3A enzyme, as shown by significant changes in its pharmacokinetics when coadministered with rifampin (a CYP3A inducer) and itraconazole (a CYP3A inhibitor).

The study demonstrated that the pharmacokinetics of zanubrutinib were consistent across Asian and non-Asian subjects, indicating that no dose adjustments are needed based on ethnicity, and the drug was well tolerated in participants.

Acalabrutinib, a second-generation BTK inhibitor, has demonstrated promising safety and efficacy in phase 1/2 clinical trials for patients with relapsed chronic lymphocytic leukemia (CLL) and pretreated mantle cell lymphoma (MCL).

The FDA has approved acalabrutinib for adult patients with MCL who have received at least one prior therapy, indicating its effectiveness as a treatment option, although further studies comparing it directly with ibrutinib and exploring combination therapies are needed.

In a phase III trial, adding ibrutinib to R-CHOP chemotherapy significantly improved event-free survival in younger patients (≤60 years) with non-GCB diffuse large B cell lymphoma (DLBCL), achieving 100% survival in the MCD and N1 genetic subtypes.

Patients with the MCD and N1 subtypes who received only R-CHOP had much lower survival rates (42.9% and 50%, respectively), highlighting the importance of targeting chronic B cell receptor signaling with ibrutinib for better outcomes.

BTK inhibitors (BTKis) have significantly improved treatment for chronic lymphocytic leukemia (CLL) by targeting Bruton's tyrosine kinase, which is crucial for B-cell receptor signaling, leading to reduced cell proliferation and activation of harmful pathways.

While BTKis like ibrutinib and acalabrutinib are effective, they come with notable long-term adverse effects, including cardiac issues and infections, highlighting the need for careful management of these side effects during treatment.

Ibrutinib has significantly improved chronic lymphocytic leukemia (CLL) treatment by providing durable responses with minimal myelosuppression, but relapses often occur due to mutations in BTK or PLCG2 that lead to resistance.

Patients with ibrutinib resistance may benefit from alternative therapies, such as the BCL2 inhibitor venetoclax or other agents targeting different pathways, as ongoing clinical trials explore combinations of these treatments.

Chronic exposure to ibrutinib led to the development of resistant B-cell lines, which showed decreased levels of FOXO3a and PTEN and increased activation of AKT, indicating a mechanism of resistance to BTK inhibition.

Combining ibrutinib with the exportin 1 inhibitor selinexor restored the nuclear function of FOXO3a and PTEN, enhancing the effectiveness of ibrutinib and overcoming resistance, suggesting a potential new treatment strategy for B-cell malignancies.
