What side effects are associated with this type of intervention?

Common treatments for B-Cell cancers, such as chemotherapy, targeted therapies (e.g., ibrutinib), and immunotherapies, often have a range of side effects. Chemotherapy can cause myelosuppression, leading to neutropenia, anemia, and thrombocytopenia, as well as gastrointestinal issues like nausea and vomiting. Targeted therapies, such as ibrutinib, may result in hematologic adverse effects, including bleeding and infections, as well as non-hematologic effects like hypertension and atrial fibrillation. Immunotherapies can lead to immune-related adverse events, including colitis, dermatitis, and endocrinopathies. Patients should discuss these potential side effects with their healthcare provider to manage and mitigate them effectively.

What prior FDA approvals exist?

The FDA has approved several drugs for the treatment of B-Cell cancers, including ibrutinib, acalabrutinib, and venetoclax. Ibrutinib and acalabrutinib are Bruton tyrosine kinase (BTK) inhibitors, which block a key enzyme in the B-Cell receptor signaling pathway, thereby inhibiting cancer cell growth. Venetoclax is a BCL-2 inhibitor that promotes cancer cell death by targeting the BCL-2 protein, which helps cancer cells survive. These drugs are used to treat various B-Cell malignancies such as chronic lymphocytic leukemia (CLL) and mantle cell lymphoma (MCL), and they represent significant advancements in targeted cancer therapy.

What other types of research exist?

Promising novel alternatives for B-Cell cancers include: 1) Ibrutinib, a BTK inhibitor, which has shown high overall response rates and improved progression-free survival in CLL. 2) Acalabrutinib, another BTK inhibitor, which has demonstrated efficacy in relapsed/refractory mantle cell lymphoma. 3) Venetoclax, a Bcl-2 inhibitor, which is effective in combination with other anti-tumor drugs. 4) Lenalidomide, an immunomodulatory drug, which has shown high response rates in relapsed/refractory mantle cell lymphoma. These therapies have been evaluated in clinical trials and have shown promising results for B-Cell malignancies.

Awards & highlights

No Placebo-Only Group

Summary

This trial tests a new drug called BGB-16673 to find the best dose for patients. It aims to determine how well the drug works and its safety. The study involves finding the right dose and expanding testing to more patients.

Who is the study for?

This trial is for people with certain B-cell malignancies, including various types of lymphoma and leukemia. Participants must have measurable disease, may have had previous treatments (specific conditions apply), and should be in a relatively stable condition as indicated by an ECOG score of 0 to 2. Those who've had other cancers within the last two years or require ongoing treatment for another cancer are not eligible.

What is being tested?

The study tests BGB-16673's optimal dosing levels in two parts: first, finding the right dose through monotherapy escalation; second, expanding safety studies at selected doses. It aims to determine how well this drug can treat different B-cell malignancies when given alone.

What are the potential side effects?

While specific side effects for BGB-16673 aren't listed here, similar drugs often cause fatigue, digestive issues like nausea or diarrhea, blood disorders such as low platelet counts or anemia, infections due to weakened immune systems, and possible allergic reactions.

Trial Design

4Treatment groups

Experimental Treatment

Group I: Part 2 (Monotherapy Dose Expansion)Experimental Treatment1 Intervention

The totality of the data from Part 1a and Part 1b will be used to further evaluate the safety and efficacy of BGB-16673 at the recommended dose(s) for Part 2 expansion in specific histologies.

Group II: Part 1c (Additional Monotherapy Safety Expansion)Experimental Treatment1 Intervention

After RP2D is determined, additional safety data will be collected to confirm RP2D for participants with selected B-cell malignancies not being evaluated in Part 2

Group III: Part 1b (Monotherapy Safety Expansion)Experimental Treatment1 Intervention

Additional participants with selected R/R B-Cell malignancies will be enrolled at selected doses to help inform the selection of the recommended phase two dose (RP2D).

Group IV: Part 1a (Monotherapy Dose Escalation)Experimental Treatment1 Intervention

Dose escalation in selected R/R B-Cell malignancies to inform safety, tolerability and MTD.

Other Research

Bruton tyrosine kinase (BTK) inhibitors, such as ibrutinib, are a common treatment for B-Cell Cancers. BTK is a crucial enzyme in the B-cell receptor (BCR) signaling pathway, which is essential for the growth and survival of B-cell malignancies. By inhibiting BTK, these drugs disrupt the BCR signaling, leading to reduced proliferation and increased apoptosis of malignant B-cells. This mechanism is particularly effective in tumors with certain genetic mutations, such as MYD88 mutations, which are common in B-Cell Cancers. The effectiveness of BTK inhibitors in targeting these pathways makes them a vital option for patients, offering improved response rates and progression-free survival.
