Given the current dynamics in the development of novel agents for CLL therapy, the task to find optimal, non-toxic combinations has become the primary goal. This article gives an update of the most interesting novel drugs. The strategy of the German CLL Study Group to use these agents in combinations is described in detail, highlighting the strategy and first results of a recently started series of phase II combination trials, the BXX series using agents such as bendamustine, idelalisib, ibrutinib, obinutuzumab, ofatumumab and venetoclax...

: In this multicenter, open-label, phase III study, patients with relapsed chronic lymphocytic leukemia (CLL) were randomized (1:1) to receive ofatumumab plus fludarabine and cyclophosphamide (OFA + FC) or FC alone; the primary endpoint being progression-free survival (PFS) assessed by an independent review committee (IRC). Between March 2009 and January 2012, 365 patients were randomized (OFA + FC: n = 183; FC: n = 182). Median IRC-assessed PFS was 28.9 months with OFA + FC versus 18...

INTRODUCTION: The therapeutic utility of the anti-CD20 monoclonal antibodies (mAbs) is currently being evaluated in multiple sclerosis (MS) in line with the better understanding of the role of B lymphocytes in MS pathogenesis. AREA COVERED: We conducted a literature search using Medline/Pub Med database of basic research and available controlled trials about anti-CD20 mAbs in MS. Additionally, ongoing studies were identified in the database. B cells exert multiple inflammatory and regulatory functions playing an important role in MS pathogenesis as is demonstrated by the production of autoantibodies, infiltration of B cells in MS lesions and the formation of ectopic B cell follicle-like structures in meninges, among others...

BACKGROUND: Rituximab, a chimeric anti-CD20 monoclonal antibody, is an effective treatment in steroid-dependent nephrotic syndrome (SDNS). However, some patients develop adverse reactions. CASE-DIAGNOSIS/TREATMENT: Patient 1, a 14-year-old boy with SDNS since the age of 2, was treated with oral prednisone, cyclosporine A (CsA) and mycophenolate mofetil. A first infusion of rituximab at age 12 years was well tolerated, but this was followed by a prolonged relapse unresponsive to oral prednisone, mycophenolate mofetil and CsA...

BACKGROUND: Chronic lymphocytic leukaemia (CLL) is the most common adult leukaemia. Combination immunochemotherapy such as fludarabine, cyclophosphamide and rituximab is the standard first line therapy in fit patients, but there is limited evidence regarding the optimal treatment of patients after relapse. Ofatumumab as monotherapy has been proven to be effective in the treatment of relapsed, refractory CLL, and as it is not myelotoxic, it is an ideal drug to combine with chemotherapy...

BACKGROUND: Although several consolidation strategies to prolong treatment-free survival (TFS) in chronic lymphocytic leukaemia have been investigated, most have proven either ineffective or toxic. Ofatumumab is a human type I anti-CD20 antibody approved by the US Food and Drug Administration as maintenance treatment of patients with recurrent or progressive chronic lymphocytic leukaemia who are in complete or partial response after at least two lines of treatment; higher efficacy might be observed if used as consolidation strategy than without consolidation in previously untreated patients...

INTRODUCTION: Rituximab plus fludarabine and cyclophosphamide (RFC) is the standard of care for fit patients with untreated chronic lymphocytic leukemia (CLL); however, its use is limited in 'unfit' (co-morbid and/or full-dose F-ineligible) patients due to its toxicity profile. We conducted a systematic review and Bayesian network meta-analysis (NMA) to determine the relative efficacy of commercially available interventions for the first-line treatment of unfit CLL patients. METHODS: For inclusion in the NMA, studies had to be linked via common treatment comparators, report progression-free survival (PFS), and/or overall survival (OS), and meet at least one of the five inclusion criteria: median cumulative illness score >6, median creatinine clearance ≤70 mL/min, existing co-morbidities, median age ≥70 years, and no full-dose F in the comparator arm...

Monoclonal antibodies represent a major advance in treatment of acute lymphoblastic leukemia (ALL). Targeted delivery of these agents based on leukemic cell-surface receptor recognition, improves efficacy and minimizes off-target toxicity. The antigens CD19, CD20, CD22 and CD52, are the most common antigens to which monoclonal antibodies in B-cell ALL have been directed. Rituximab, an anti-CD20 antibody, in combination with conventional chemotherapy has been shown to improve survival in newly diagnosed CD20 positive B-cell ALL...

BACKGROUND: Patients diagnosed with chronic lymphocytic leukemia (CLL) are usually elderly and frequently have a number of comorbidities. Health-related quality of life (HRQoL) for these patients is of utmost importance and should be taken into consideration when assessing new treatment options. The combination of ofatumumab with chlorambucil has shown longer progression-free survival compared with chlorambucil alone. In this study, we aim to assess how this treatment combination affects patients' health-related quality of life and patient-reported symptoms...

The management of patients with chronic lymphocytic leukemia (CLL) has radically improved over the last few years with the addition of anti-CD20 monoclonal antibodies (MoAbs) to chemotherapy. Chlorambucil has been considered for decades as a suitable therapeutic option for frail patients. Taking into account the advantage offered by the addition of MoAbs to chemotherapy, different studies up to now have explored the feasibility of chlorambucil-based chemoimmunotherapies in treatment-naïve CLL. COMPLEMENT1 is a prospective, randomized, open-label trial evaluating the efficacy and safety of ofatumumab added to chlorambucil, compared with chlorambucil in monotherapy, in the setting of untreated patients with CLL considered unsuitable for a fludarabine-based approach...

Rheumatoid arthritis (RA) is a chronic inflammatory autoimmune condition viewed as a severe destructive disease. The treatment strategies include anti-CD20 monoclonal antibody (mAb)-targeting B cells. Ofatumumab specifically targets a membrane-proximal epitope on the CD20 molecule distinct from other anti-CD20 antibodies including rituximab and ocrelizumab, and bind the epitope located on the large loop of CD20. This explains a more durable B-cell depletion and a different pharmacodynamic. We review the pharmacodynamic of B-cell depletion and analyze the results in RA and other B-cell-mediated autoimmune diseases...

Rituximab is frequently used in systemic lupus erythematosus; however, side effects such as infusion-related reactions limit its use. In this case report, we describe, for the first time, treatment with ofatumumab in four patients with lupus nephritis. The treatment was well tolerated in three of the patients, and a reduction of proteinuria was seen in all cases. This emphasizes the importance of alternative B-cell-depleting therapies in patients with an initial good response to rituximab, but who develop side effects...

: Relationships between patient characteristics, ofatumumab pharmacokinetics, and treatment outcomes were investigated in this phase 2 trial of ofatumumab plus fludarabine and cyclophosphamide (FC) in untreated chronic lymphocytic leukemia. Patients were randomized 1:1 to receive 500 or 1000 mg ofatumumab (Cycle 1; 300 mg) plus FC every 4 weeks for six cycles. Median Cmax and Ctrough values were similar at Cycle 1 regardless of the ultimate clinical outcome. At later doses, these values were higher for patients with complete response (CR) than for other patients...

Despite the recent advances in treatment of CLL with targeted agents such as ibrutinib, availability of nonchemotherapy based therapies is desired. Given the 58% response rate (1996 NCI-WG criteria) of single agent ofatumumab in CLL refractory to fludarabine and alemtuzumab, we initiated a phase II trial examining response, safety, and progression-free survival (PFS) of ofatumumab as front-line monotherapy. Patients enrolled included untreated, symptomatic CLL patients over the age of 65 or those who were inappropriate/did not desire chemotherapy...

Richter syndrome (RS) is associated with chemotherapy resistance and a poor historical median overall survival (OS) of 8-10 months. We conducted a phase II trial of standard CHOP-21 (cyclophosphamide, doxorubicin, vincristine, prednisolone every 21 d) with ofatumumab induction (Cycle 1: 300 mg day 1, 1000 mg day 8, 1000 mg day 15; Cycles 2-6: 1000 mg day 1) (CHOP-O) followed by 12 months ofatumumab maintenance (1000 mg given 8-weekly for up to six cycles). Forty-three patients were recruited of whom 37 were evaluable...

In Rheumatoid Arthritis (RA) and Systemic Lupus Erythematosus (SLE), B-cell depletion therapy using rituximab results in variable clinical responses between individuals, which likely relates to variable B-cell depletion in the presence of immune defects. Outcomes in clinical trials with other type I anti-CD20 mAbs, ocrelizumab and ofatumumab, are comparable to rituximab. A mechanistically different type II mAb, obinutuzumab (OBZ), with greater capacity for B-cell depletion, has recently entered clinical trials in SLE...
