UNASSIGNED: This article provides a short summary of 5-year results from the iNNOVATE trial. The original paper was published in the Journal of Clinical Oncology in October 2021. People with Waldenström\'s macroglobulinemia (WM) were randomly divided into two groups of 75 people each. One group received a combination treatment composed of two drugs, ibrutinib plus rituximab, and the other group took placebo (\"sugar pill\") plus rituximab. Ibrutinib (also known by the brand name Imbruvica®) is a drug that reduces cancer cells\' ability to multiply and survive. Ibrutinib is an FDA-approved drug for the treatment of WM. Rituximab is a drug that helps the immune system find and kill cancer cells. Participants in the trial were treated and their health monitored for up to 5 years (63 months).
UNASSIGNED: During the 5 years of monitoring, more people who took ibrutinib plus rituximab experienced an improvement in their disease and lived longer without their disease getting worse compared to those who took placebo plus rituximab. Side effects from ibrutinib and rituximab were manageable and generally decreased over time. Participants in both study groups reported improvements in quality of life, but those who took ibrutinib plus rituximab reported significantly greater improvement in their quality of life (as measured by FACT-An score) compared to those who took placebo plus rituximab.
UNASSIGNED: These results show that ibrutinib plus rituximab is better than rituximab alone in people with WM and that ibrutinib plus rituximab is safe and effective in the long term. This information confirms the role of ibrutinib plus rituximab as a standard of care for WM. Clinical Trial Registration: NCT02165397 (ClinicalTrials.gov).

UNASSIGNED: Orelabrutinib is a novel, small molecule, selective irreversible Bruton tyrosine kinase inhibitor. The purpose of this study was to evaluate the efficacy and safety of orelabrutinib in patients with relapsed or refractory Waldenström\'s macroglobulinemia (R/R WM).
UNASSIGNED: This is a prospective, multicenter study of orelabrutinib in patients with WM who had at least one prior line of treatment. Orelabrutinib was administered orally at a daily dose of 150 mg until disease progression or unacceptable toxicity. The primary endpoint was major response rate (MRR) assessed by the Independent Review Committee (IRC) according to IWWM-6. This study is registered with ClinicalTrials.gov, NCT04440059. This trial was also registered on Center for Drug Evaluation (www.chinadrugtrials.org.cn) in March 2019, with a number of CTR2019036.
UNASSIGNED: Between August 2019 and December 2020, 66 R/R WM patients were assessed for eligibility. Forty-seven eligible patients were evaluated for efficacy at a median follow-up of 16.4 months (interquartile range: 12.5, 19.5). As assessed by IRC, the MRR was 80.9%, and the overall response rate was 89.4%. The median time to at least a minor response was 1.9 months. The PFS rates was 89.4% at 12 months. For patients with MYD88L265P /CXCR4NEG, MYD88L265P /CXCR4 S338X, and MYD88NEG /CXCR4NEG mutations, the MRRs were 84.6%, 100%, and 25.0%. Most adverse events were Grades 1 or 2 (91.0%). The common grade 3 or higher adverse events occurring were neutropenia (10.6%), thrombocytopenia (6.4%), and pneumonia (4.3%). Serious adverse events (SAE) occurred in 10 patients (21.3%). One treatment-related death was reported (hepatitis B reactivation).
UNASSIGNED: Orelabrutinib has shown good efficacy and manageable safety profiles in patients with R/R WM.

Waldenstrom\'s macroglobulinemia (WM) is considered by the Revised European American Lymphoma (REAL) and World Health Organization (WHO) as a clinical lympho plasmacytic syndrome associated with high monoclonal (IgM) secretion. The hyper viscosity syndrome is associated with several clinical disorders of monoclonal IgM. Patients with clinical symptoms of hyper viscosity should be treated with plasma pheresis, which is limited by its non-selective removal of all plasma components. These limitations have steered efforts to find a more specific removal according to clinical needs and avoiding plasma components replacement. Removal by specific adsorption is the most powerful selective apheresis technique. The active adsorbed ligand is covalently bound to an insoluble matrix through which plasma is passed. Amino acids have been introduced as ligands in clinical apheresis for the removal of auto antibodies associated with autoimmune diseases. The present preliminary study describes the binding of monoclonal IgM antibodies from sera of patients with WM, on histidine immobilized to activated sepharose. The advantages of efficient binding and elution, suggest histidine adsorbents as prospective clinical means suitable for the removal of monoclonal IgM from sera of patients diagnosed with WM. The advantages of efficient adsorption and elution, non toxicity of histidine, good selectivity, good stability, as well as their low cost strongly suggest histidine adsorbents as prospective clinical means suitable for the removal of monoclonal IgM from sera of patients diagnosed with WM.
