Acalabrutinib

The purpose of this study is to investigate the efficacy and safety of fixed-duration sonrotoclax (also known as BGB-11417) plus zanubrutinib (also known as BGB-3111) (SZ) compared with fixed-duration of venetoclax plus acalabrutinib (AV) in participants with previously untreated chronic lymphocytic leukemia (CLL).

The goal of this study is to evaluate nemtabrutinib compared with investigator's choice of ibrutinib or acalabrutinib in participants with chronic lymphocytic leukemia (CLL)/small lymphocytic lymphoma (SLL) who have not received any prior therapy. The primary hypotheses are that (1) nemtabrutinib is non-inferior to ibrutinib or acalabrutinib with respect to objective response rate (ORR) per International Workshop on Chronic Lymphocytic Leukemia (iwCLL) Criteria 2018 by blinded independent central review (BICR) and (2) nemtabrutinib is superior to ibrutinib or acalabrutinib with respect to progression free survival (PFS) per iwCLL Criteria 2018 by BICR.

This study will evaluate the efficacy and safety of finite-duration acalabrutinib plus venetoclax therapy in patients with relapsed CLL or SLL, and have previously responded to first line (1L) cBTKi + BCL2i therapy (± obinutuzumab) and maintained a response for at least two years post-treatment.

The purpose of this study is to assess the safety and efficacy of surovatamig (formerly AZD0486) administered as monotherapy or in combination with other anticancer agents in participants with hematological malignancies

This phase II trial studies how well acalabrutinib and venetoclax with or without early obinutuzumab work for the treatment of chronic lymphocytic leukemia or small lymphocytic lymphoma that is high risk, has come back (recurrent), or does not respond to treatment (refractory). Acalabrutinib may stop the growth of cancer cells by blocking some of the enzymes needed for cell growth. Venetoclax may stop the growth cancer cells by blocking BCL-2 protein needed for cell growth. Immunotherapy with monoclonal antibodies, such as obinutuzumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Giving acalabrutinib and venetoclax together with early obinutuzumab may improve clinical outcomes and control the disease.

The study will measure the safety, tolerability, and efficacy with acalabrutinib in combination with rituximab in treatment-naïve elderly and/or frail patients with diffuse large B-cell lymphoma (DLBCL), who are otherwise unsuitable for standard front line chemoimmunotherapy treatments.

Background: Diffuse large B-cell lymphoma is the most common type of non-Hodgkin lymphoma. Most people with this cancer can be cured. But those who are not cured have a poor prognosis. Researchers want to add another drug to standard treatment see if it can improve the cure rate. Objective: To see if the drug acalabrutinib given with rituximab and standard combination chemotherapy can improve the cure rate of aggressive B-cell lymphomas such as diffuse large B-cell lymphoma. Eligibility: People ages 18 and older with an aggressive B-cell lymphomas that have not been treated Design: Participants will be screened with: Blood and urine tests Physical exam Medical history Tumor biopsy Bone marrow biopsy: A needle will remove marrow from the participant s hipbone. Lumbar puncture: If necessary, a needle will remove fluid from the participant s spinal canal. Imaging scans Participants will take the study drug for up to 14 days. It is a pill taken 2 times a day. Then they will have more scans. They will get rituximab and chemotherapy. They may get these drugs through a needle in an arm vein. Or they may them through a tube placed in a vein in their chest or in their neck. They might also keep taking the study drug. Each treatment cycle lasts 21 days. They will have up to 6 cycles. Participants may have 4 doses of another drug injected into their spinal fluid. Participants will have repeats of the screening tests throughout the study. Participants will have a follow-up visit 30 days after their last treatment, then every 3 months for 2 years, then every 6 months for 3 years, and then yearly.
