Long Term Effect on Immune Response After Pneumococcal Vaccination in Patients With Chronic Lymphocytic Leukemia and Evaluation of the Effect of Revaccination
A randomized, multi-centre trial was conducted between 2013-2016, including 128 patients with untreated CLL from eight hematological clinics in Sweden. Vaccination with polysaccharide pneumococcal vaccine (PPSV23) or conjugated pneumococcal vaccine (PCV13) was performed and the results were published 2018. PCV13 showed a superior immune response, measured as OPA (opsonophagocytic assays) and ELISA (enzyme-linked immunosorbent assay), compared to PPSV23. Immune cells analyses after primary immunization will be performed. Between 2019-2021 a prospective follow up study was conducted of the same cohort and also included a control group. The study participants have been revaccinated with pneumococcal vaccines with the aim to evaluate the effect of repeated dose of PCV13. The antibody response (measured as titer with FMIA (fluorescent multiplexed bead-based immunoassay) and antibody function with MOPA (multiplexed opsonophagocytic assay) will be performed. Studies investigating the dynamics of immune cells before and after primary immunization and revaccination will be performed. The study will give important answers about the optimal vaccination strategy in patients with CLL and can improve the vaccination recommendations in immunocompromised patients.

BeliVeR A Phase II Trial of Belimumab in Combination With Rituximab/Venetoclax in Patients With Refractory or Relapsed Chronic Lymphocytic Leukemia
This study is a phase II trial of belimumab in combination with rituximab/venetoclax in patients with refractory or relapsed chronic lymphocytic leukemia (CLL). Treatment of CLL has drastically changed in the past years as new therapeutic agents have gained clinical approval. The combination rituximab/venetoclax over a course of two years is approved as second line therapy especially in patients with high risk CLL (del17p), showing high remission rates and achievement of MRD (minimal residual disease) negativity. The next goals in CLL therapy are now to increase the rate of MRD negativity and to achieve an earlier MRD negativity during the course of treatment to allow for a reduction of treatment time and therefore treatment-induced toxicities. In line with other hematologic diseases, progression free survival depends on remission status, especially MRD negativity, after last treatment as MRD positivity after therapy indicates the persistence of treatment resistant CLL cells. One mechanism of therapy resistance has been described as reduced sensitivity to rituximab-induced antibody dependent cell-mediated cytotoxicity (ADCC) by natural killer (NK) cell production of B-lymphocyte stimulator (BlyS, also called BAFF), which can be bound by belimumab, a human anti-BAFF antibody. Moreover, recombinant human (rh)BAFF can dose dependently reverse cytotoxic effects of venetoclax, which could also be restored by the application of belimumab. This led to the conceptualization of this clinical trial, in which belimumab is applied as a weekly subcutaneous injection in combination with standardrituximab/venetoclax treatment for up to 24 months in relapsed and refractory CLL patients. By removing BAFF from the CLL microenvironment we aim to increase the efficacy of rituximab/venetoclax treatment to achieve higher and earlier MRD negativity rates and allow for an abbreviated treatment.

STop and Restart Acalabrutinib In fRail Patients With Previously Untreated Chronic Lymphocytic Leukemia
The irreversible Bruton's Tyrosine Kinase (BTK) inhibitor acalabrutinib (ACA) has potent clinical activity as a single agent in patients with treatment naive and Relapsed/Refractory Chronic Lymphocytic Leukemia (CLL). However, a growing body of concerns is raising regarding the unlimited administration of targeted therapy as BTKi. First, long-term treatments expose the patients to increased risk of specific adverse events (infections, bleeding events or cardiovascular problems). Second, continuous administration might also increase the risk of clonal evolution and therapeutic resistance resulting from genetic alterations such as BTK or PLCG2 mutations. Discontinuation of therapy after a fixed period is expected to prevent these events. Rapid and deep responses yielded by ACA in elderly patients pave the way of investigating a limited 18-months period schedule. This study aims to investigate the 1-year PFS upon ACA discontinuation and efficacy of restarting ACA upon symptomatic relapse.

Exercise Training to Promote Resilience to Chronic Lymphocytic Leukemia in Older Adults by Enhancing Physical and Immunological Reserve
PURPOSE: The purpose of the study is to determine the effects of 12-weeks of exercise training on physical reserve, as measured by aerobic capacity, strength and physical function, in patients with CLL. Further, it is our aim to assess relationships with changes in physical reserve and resilience to the patient's cancer, as measured by immune cell counts, tumor cell killing and antibacterial functions. DESIGN: Subjects will have confirmed treatment naïve CLL. Subjects will be assigned to either a 12-week control (no supervised exercise) or an intervention (HIIT) group. Before and after the 12 week program subjects will undergo several tests including: 1) a maximal treadmill test, 2) body composition, 3) muscle strength and endurance, 4) physical activity levels, 5) blood measures (e.g. immune and inflammatory functions). Subjects in the HIIT group will complete a 12-week supervised exercise training program consisting of HIIT and strength training. DATA ANALYSES & SAFETY ISSUES: This is a pilot study, with the goal of assessing whether exercise training causes a change in aerobic fitness (VO2peak), muscle function, and immunological measures. Vo2peak will be measured by a cardiopulmonary exercise test, muscle function will be measured by strength tests, and immunological functions will be measured from blood samples. For outcomes, group change differences from baseline to 12-weeks will be compared by ANCOVA. The data will be used to provide power calculations for future grant proposals. High Intensity Interval Training is a very safe exercise modality. The regular use of vigorous intensity exercise intervals have been used extensively in exercise training. In fact, the exercise intervals will start at levels lower and will be of shorter duration than were used during the maximal exercise test. They will then be carefully and slowly made to be more challenging as each subject is able to safely tolerate. HYPOTHESIS: The investigators hypothesize that HIIT will be a feasible exercise intervention for people with CLL and will result in improvements in markers of health and fitness.

Metabolic Profiling of Leukemic Cells Through Isotope Tracing in Patients With CLL
Metabolic reprogramming has been identified as a hallmark of cancer. Almost a century after Otto Warburg initially discovered increased glycolytic activity in tumor tissue ("Warburg effect"), therapeutic targeting of cancer metabolism has become a field of intense research effort in cancer biology. A growing appreciation of metabolic heterogeneity and complexity is currently reshaping investigators "simplistic" understanding of metabolic reprogramming in cancer. Discovering metabolic vulnerabilities as new treatment targets for cancer requires systematic dissection of metabolic dependencies, fuel preferences, and underlying mechanisms in the specific physiological context. However, today's data on cancer cell metabolic signatures and heterogeneity in their physiological habitat of the human organism is sparse to non-existent representing a critical knowledge gap in designing effective metabolic therapies. Here, the investigators propose a "top-down" approach studying cancer cell metabolism in patients followed by mechanistic in-depth studies in cell culture and animal models to define metabolic vulnerabilities. Investigators will develop a metabolic tracing method to quantitatively characterize metabolic signatures and fuel preferences of leukemic lymphocytes in patients with chronic lymphocytic leukemia (CLL). Isotopic metabolic tracers are nutrients that are chemically identical to the native nutrient. Incorporated stable, non-radioactive isotopes allow investigators to follow their metabolic fate by monitoring conversion of tracer nutrients into downstream metabolites using cutting-edge metabolomics analysis. Using this method, investigators propose to test the hypothesis that leukemic lymphocytes show tissue-specific metabolic preferences that differ from non-leukemic lymphocytes and that ex vivo in-plasma labeling represents a useful model for assaying metabolic activity in leukemic cells in a patient-specific manner.
