Chronic Lymphocytic Leukaemia

Researchers are looking for new ways to treat people with B-cell cancers. In this trial, researchers will look at chronic lymphocytic leukemia (CLL) and small lymphocytic lymphoma (SLL). These are blood cancers that affect B-cells in the blood, bone marrow, or lymph nodes. The goals of this trial are to learn about: * The safety of MK-1045 and if participants tolerate it. Tolerate means participants will receive trial treatment unless they need to stop treatment due to health problems. * The number of participants who respond. Respond means the number of cancer cells goes down or signs of cancer go away.

The purpose of this study is to evaluate the safety and efficacy of nemtabrutinib (formerly ARQ 531) in participants with hematologic malignancies of chronic lymphocytic leukemia (CLL)/ small lymphocytic lymphoma (SLL), Richter's transformation, marginal zone lymphoma (MZL), mantle cell lymphoma (MCL), follicular lymphoma (FL), and Waldenström's macroglobulinemia (WM).

This will be a global Phase IV, open-label, randomised study to evaluate the safety and tolerability of acalabrutinib (monotherapy, 100 mg orally \[po\], twice daily \[bd\]) compared to investigator's choice of treatment, in patients with CLL (TN or R/R) and moderate to severe cardiac impairment. Patients with moderate to severe cardiac impairment will include those with moderate to severe cardiac conditions, who may have been excluded from previous acalabrutinib clinical trials and in whom the safety of acalabrutinib was not systematically assessed. The study is planned to take place in approximately 25 centres globally. The study will be conducted in centres that have established close collaboration between the Haematology and Cardiology divisions, preferably with a cardio-oncologist on the team. An IDMC will be responsible for making recommendations for study continuation.

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

The purpose of this transgene assay testing service is to evaluate tumor samples for transgene levels in patients who received a commercially available Bristol-Myers Squibb manufactured gene modified cellular therapy and have reported a qualifying second malignancy.
