New drug for non-Hodgkin lymphoma and chronic lymphocytic leukemia passes early test

(Houston Methodist) A new chemotherapy drug being investigated for its potency against two types of cancer was found by scientists at Houston Methodist and seven other institutions to be effective in about one-third of the 58 patients who participated in a phase I study.

354Background: Each year more than 90,000 cases of chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL) are expected in the US. The standard of care includes immuno-chemotherapy with alkylating agents in combination with an anti-CD20 monoclonal antibody, in addition to targeted therapies such as Bruton’s tyrosine kinase inhibitors. While immuno-chemotherapy regimens are initially effective in inducing responses, most patients inevitably relapse and the same therapies show decreasing efficacy with repeated administration. In recent years, CD37 has emerged as a new therapeutic target for B-cell malignancie...

This report concerns the effect of GA101 on Ca2+ signaling and its involvement in the direct cell death induced by GA101. We reveal that GA101 triggered an intracellular Ca2+ increase by mobilizing intracellular Ca2+ stores and activating Orai1-dependent Ca2+ influx in non-Hodgkin lymphoma cell lines and primary B-Cell Chronic Lymphocytic Leukemia (B-CLL) cells. According to the cell type, Ca2+ was mobilized from two distinct intracellular compartments. In Raji, BL2, and B-CLL cells, GA101 induced a Ca2+ release from lysosomes, leading to the subsequent lysosomal membrane permeabilization and cell death. Inhibition of this...

Chronic lymphocytic leukemia (CLL) is the most common leukemia in adults in western countries, accounting for approximately one quarter of all leukemias and Non-Hodgkin lymphoma (NHL) caused an estimated 200,000 cancer deaths worldwide in 2014. More than 90,000 cases of chronic lymphocytic leukemia (CLL) and non-Hodgkin lymphoma (NHL) are expected in the US each year. Immuno-chemotherapy using anti-CD20 monoclonal antibodies (mAb) in combination with DNA alkylating agents is the front-line therapy of CLL and NHL.

Conclusion: While providing potential clinical benefit, CAR T cell therapy utilizes resources across the therapeutic spectrum, and increasing use of this therapeutic modality can create challenges in institutional resource capacity. Identifying these resources will allow for better care delivery and allocation of funds. Further refinement of CAR T cell products and improvements in CAR T cell-related toxicity management may permit safer delivery of this therapy and reduce costs per patient. Additional analysis of resource utilization among patients treated with commercial CAR T cell products, as well as comparison with alte...

IntroductionLymphoma patients are at increased risk of thromboembolic events (TE), however, thromboprophylaxis in these patients is largely under utilized. Actual guidelines recommend different models for thromboembolic risk estimation in cancer patients. Proposed models are of limited use in lymphoma patients as their development is not based on specific characteristics for this patient population. Previously, we developed and internally validated a simple model, based on individual clinical and laboratory patient characteristics that would classify lymphoma patients at risk for a TE. The variables independently associate...

Background: CLL is the most common leukemia diagnosis in adults and its treatment has undergone significant change from chemotherapy, to immunotherapy and now targeted kinase inhibitors, leading to improved overall survival (OS). With improving survivorship, SPMs can occur but an in-depth analysis of risks and trends of SPMs in CLL survivors is lacking. We performed a population-based analysis to evaluate this.Methods: Patients in the Surveillance, Epidemiology and End Results (SEER) database diagnosed with CLL between 1973-2015 were included. Due to variation in management techniques over time, the cohort was divided in f...

This study aimed to answer both questions.Patients and MethodsWe reviewed 14 Alliance for Clinical Trials in Oncology trials that enrolled CLL and/or NHL patients between 2004–2014. Toxicity was assessed per the NCI-CTCAE (version 3–5). Probabilities of experiencing grade three or four hematologic and non-hematologic toxicities were modeled as a function of clinical and disease-related factors using logistic regression.Results1199 patients (409 age ≥ 65; 790 age
