Local radiotherapy and measurable residual disease-driven immunotherapy in patients with early-stage follicular lymphoma (FIL MIRO): final results of a prospective, multicentre, phase 2 trial. (PubMed, Lancet Haematol)
Local radiotherapy is frequently not associated with the eradication of follicular lymphoma. An MRD-driven, anti-CD20 monoclonal antibody consolidation enables molecular remission to be reached in almost all patients and is associated with a reduced incidence of relapse over time. A clinical advantage of an MRD-driven consolidation is therefore suggested.

Maintenance therapy for chronic lymphocytic leukaemia. (PubMed, Cochrane Database Syst Rev)
There is currently moderate- to very low-certainty evidence available regarding the benefits and harms of maintenance therapy in people with CLL. Anti-CD20 mAbs maintenance improved PFS, but also increased grade 3/4 AEs and all AEs. IMiD maintenance had a large effect on PFS, but also increased grade 3/4 AEs. However, none of the above-mentioned maintenance interventions show differences in OS between the maintenance and control groups. The effects of alemtuzumab maintenance are uncertain, coupled with a warning for drug-related infectious toxicity. We found no studies evaluating other novel maintenance interventions, such as B-cell receptor inhibitors, B-cell leukaemia-2/lymphoma-2 inhibitors, or obinutuzumab.

Deep Immune Profiling Identifies Novel T-Cell Subpopulations That Influence Specific Clinical Outcomes in Chronic Lymphocytic Leukaemia (CLL) (ASH 2023)
The discovery cohort comprised pre-treatment samples from 79 CLL patients enrolled in the NCRI RIAltO trial (NCT01678430) who underwent factorial randomisation to ofatumumab and either bendamustine or chlorambucil, with or without idelalisib. The present study has identified three previously undescribed T-cell subpopulations that appear to influence the risk of infection, SPM, and death in patients with CLL receiving frontline chemo-immunotherapy. Further studies are warranted to validate these findings in the setting of targeted agents and in patients receiving CIT for other haematological malignancies.

Pts who were MRD+ by both NEST and RQ in the BM a/o PB after IFRT or who became MRD+ during the follow-up were treated with 8 weekly doses of the anti-CD20 monoclonal antibody ofatumumab (OFA)...A consolidation strategy with more effective agent should be advisable. With these limits, a clinical advantage of the MRD-driven treatment strategy is suggested, although not largely applicable.

Multi-Omics Exploration of Adaptive Mechanism to BTK Inhibition By Ibrutinib in CLL Identified TMBIM6/BI-1 As a Poor Prognosis Variable and Potential Therapeutic Target (ASH 2023)
Blood samples from 28 patients from GELLC7 trial (NCT03280160, ibrutinib followed by ofatumumab consolidation) were collected before treatment (BT), and 1, 3, 6 and 12 months on treatment (at least two timepoints). Ibrutinib in T cells reduced the expression of exhaustion markers, Tregs and Tfh cells. In CLL cells, we observed a downregulation of markers related to adhesion, immunosuppression and migration, but an overexpression of TMBIM6 in CLL cells that retained migrative capacity towards CXCL12 under ibrutinib. Finally, we identified TMBIM6 expression as an independent poor prognostic factor and a potential novel target for CLL.

High Dimensional Detection of Non-Malignant B-Cells and Its Clinical Implications in Patients with Chronic Lymphocytic Leukaemia (CLL) Undergoing Frontline Therapy (ASH 2023)
Patients were randomly assigned to receive bendamustine or chlorambucil plus ofatumumab, with or without idelalisib. To our knowledge, this is the first study to identify correlations between the re-emergence of non-malignant B-cells following anti-CLL therapy and specific clinical endpoints such as haematopoietic recovery, serum Ig levels, TTP and OS. Although further validation is required in the context of targeted agents, our findings suggest that therapy-induced re-emergence of non-malignancy B-cells may have important biological and clinical implications in CLL.

Immunomodulatory Effects of Chemo-Immunotherapy ± Idelalisib in Chronic Lymphocytic Leukaemia (CLL) (ASH 2023)
Patients were randomly assigned to receive ofatumumab plus either bendamustine or chlorambucil, with or without idelalisib. CIT results in profound immune changes that persists up to 18.5 [16.1 – 22.6] months following treatment. Furthermore, the overall effect of these changes further differentiates the CLL-associated immune profile from that of HC, deepening the existing T-cell dysfunction irrespective of chemotherapy choice, or the addition of idelalisib. Our study has important potential implications for patients receiving CIT in a range of clinical settings and supports the move towards more targeted agents that are less likely to cause indiscriminate immune perturbation.

BCMA-Directed Low Dose Alpha-Emitter Therapy Eliminates Minimal Residual Disease in a Multiple Myeloma Mouse Xenograft Model (ASH 2023)
We conjugated a human IgG1 anti-BCMA mAb and an isotype matched nonbinding control mAb (ofatumumab), with the amine-reactive labeling agent B10-NCS to enable 211At radiolabeling... Tumor responses are encouraging with 100% of mice cured of MM after receiving low doses of BCMA targeted 211At. While we have previously demonstrated that 211At-CD38 could eliminate MM in a similar model system, in that setting fewer than 50% of mice bearing the same NCI-H929Luc tumors, and treated with 8 μCi of 211At, survived to day 150 [O'Steen S. Blood, 2019]. In contrast, here we show that 100% of mice are cured after receiving 6 μCi of 211At-BCMA-B10.

Monoclonal antibodies binding to different epitopes of CD20 differentially sensitize DLBCL to different classes of chemotherapy. (PubMed, Front Oncol)
We then discovered that R and ofatumumab differentially synergize with the cytotoxic and cytostatic capabilities of CHOP in separate distinct subsets of B-cell lymphoma cell lines, thereby expanding favorable immunochemotherapy interactions across a greater range of cell lines beyond those induced by R-CHOP. This finding may have immediate clinical significance because both immunochemotherapy combinations are already FDA-approved with no difference in toxicity across phase I, II, and III clinical trials. Therefore, this finding could inform a new precision medicine strategy to provide additional therapeutic benefit to patients with B-cell lymphoma using immunochemotherapy combinations that already meet the clinical standard of care.

Anti-CD19 CAR T-cell therapy for patients with Richter syndrome: A LYSA Study from the DESCAR-T Registry (IWCLL 2023)
Indeed, chemoimmunotherapy regimens used in de novo DLBCL failed to induce a significant complete remission rate (CRR) (R-CHOP, 7%; ofatumumab-CHOP, 27%) [1,2]...Nine (60%) patients received chemo- immunotherapy, 9 (60%) had been exposed to ibrutinib including 4 (26.7%) to both ibrutinib and venetoclax (data collection ongoing for one patient)...Following CAR T-cell infusion with axi-cel (7 patients) or tisa-cel (8 patients), 8 (53.3%) patients were alive, 7 (46.6%) patients died (3 from acute toxicity with two CRS and one neurotoxicity, and 4 from disease progression)...Tocilizumab was administered to 13 (87%) patients... CD19-directed CAR T-cell therapy showed high response rates and an encouraging survival in our series of heavily pretreated RS patients. Frequency of CAR T-cell- specific adverse events was in the range of what is observed in de novo DLBCL while severity appeared higher [3,4].

Autoimmune cytopenias in patients with chronic lymphocytic leukemia treated with targeted drugs: pooled analysis of clinical trials from the German CLL Study Group (GCLLSG) (IWCLL 2023)
With a median observation time of 38.6 months (range 1.1–76.3) a total of 981 patients treated first-line (85.4%) or relapsed/refractory (14.6%) with at least one dose of venetoclax plus CD20 antibody (n = 520), venetoclax plus BTKi (n = 297), BTKi (n = 128), or idelalisib (n = 36) were included. All patients received therapy with anti-CD20 antibody obinutuzumab (n = 685), rituximab (n = 231), or ofatumumab (n = 65)... Autoimmune cytopenias may occur with an incidence of 9% in patients with CLL treated with targeted drugs. When comparing different treatment modalities, venetoclax plus BTKi had the highest AIC incidence. Adverse risk factors for AIC were venetoclax-based treatment, advanced Binet stage, female sex and TP53 disruptions.

Complement system in Anti-CD20 mAb therapy for cancer: A mini-review. (PubMed, Int J Immunopathol Pharmacol)
Therapy with anti-CD20 monoclonal antibodies (mAbs), for example, rituximab and ofatumumab, is a well-established treatment for lymphoid malignancies, and CDC is one of the main mechanisms underlying their anti-cancer activity. Previous studies have reported that a gain-of-function in a certain complement component can boost the cytolytic activity of anti-CD20 mAbs. Through reviewing the literature on complement system control and anti-CD20 mAbs, this article aims to provide a thorough understanding of the potential of targeting complement components in lymphoma therapy.

IBRUTINIB FOR TREATMENT OF RELAPSED-REFRACTORY CHRONIC LYMPHOCYTIC LEUKEMIA: A MATCHING-ADJUSTED INDIRECT COMPARISON OF 3 RANDOMIZED PHASE 3 TRIALS (EHA 2023)
Within R/R CLL, single-agent ibrutinib was evaluated in 3 randomized phase 3 trials: RESONATE (vs ofatumumab), ALPINE (vs zanubrutinib), and ELEVATE-RR (vs acalabrutinib in patients with del(11q) or del(17p) mutations). In phase 3 randomized trials in R/R CLL, continuous ibrutinib treatment was associated with robust PFS and ORR benefits. Ibrutinib outcomes were consistent between RESONATE and ELEVATE-RR; however, significant differences in the performance of ibrutinib within ALPINE were identified. Indirect comparisons have limitations,since each trial, protocol, and patient profile are unique; however, these results highlight the need for further research on which elements of protocol design, center selection, or treatment delivery may lead to a significant impact on the performance of a given BTKi in clinical trials.

HYPER-CVAD WITH BLINATUMOMAB AND INOTUZUMAB OZOGAMICIN FOR PATIENTS WITH NEWLY DIAGNOSED PHILADELPHIA CHROMOSOME-NEGATIVE B-CELL ACUTE LYMPHOBLASTIC LEUKEMIA: A PHASE II STUDY (EHA 2023)
Pts received hyper-CVAD alternating with high-dose methotrexate and cytarabine for up to 4 cycles, followed by 4 cycles of blinatumomab at standard doses. Pts with CD20+ disease (≥1% cells) received 8 doses of ofatumumab (2000 mg) or rituximab (375 mg/m2)...In pts with newly diagnosed Ph-negative B-cell ALL receiving hyper-CVAD with sequential blinatumomab, the addition of INO is safe and may improve survival.
