REVIEW
Sohita Dhillon
Obinutuzumab (Gazyva(®), Gazyvaro(®)) is a recombinant, monoclonal, humanized and glycoengineered, type II, anti-CD20, IgG1 antibody. It has recently been granted an additional indication for the treatment of patients with follicular lymphoma who relapsed after, or are refractory to, a rituximab-containing regimen. In the primary analysis of the large, phase III GADOLIN study, induction therapy with obinutuzumab plus bendamustine followed by obinutuzumab maintenance prolonged progression-free survival (PFS) to a statistically significant extent relative to induction with bendamustine monotherapy in patients with indolent non-Hodgkin's lymphoma (iNHL)...

Polymorphonuclear neutrophils (PMN) have previously been reported to mediate phagocytosis of anti-CD20 opsonized B-cells from CLL patients. However recent data have suggested that PMN, like macrophages, can also mediate trogocytosis. We have performed experiments to more precisely investigate this point and discriminate between trogocytosis and phagocytosis. In live cell time-lapse microscopy experiments, we could not detect any significant phagocytosis by purified PMN of anti-CD20-opsonized CLL B-cells, but only the repeated close contact between effectors and targets, suggesting trogocytosis...

Pier Luigi Zinzani, Alessandro Broccoli
Efficacy, safety and mechanisms of action of novel agents in marginal zone lymphoma patients, both with a nodal and extranodal presentation, are reviewed. Data on lenalidomide, bortezomib and (90)yttrium-ibrutumomab tiuxetan are obtained from trials specifically designed for patients affected by marginal zone lymphoma and with various disease presentations. The role of targeted agents, such as obinutuzumab, ibrutinib and idelalisib, and of some very new drugs (venetoclax, copanlisib, ublituximab and TGR-1202) is also discussed, taking into account the most relevant experiences in patients with indolent non-Hodgkin's lymphomas...

The CD20 marker continues to be exploited as a therapeutic target for non-Hodgkin's lymphoma. Obinutuzumab is part of a new generation of anti-CD20 monoclonal antibodies, which are synthesized using molecular engineering technology, resulting in novel target epitopes and unprecedented optimization of antibody-dependent cellular cytotoxicity and antibody-dependent cellular phagocytosis. Rituximab is the current gold standard for anti-CD20 therapy, yet despite outstanding results published over the past decade, many patients continue to relapse after anti-CD20 regimens...

REVIEW
Benjamin N Voorhies, Deborah M Stephens
The front-line management of patients with chronic lymphocytic leukemia (CLL) has evolved significantly in recent years due to introduction of novel, targeted agents. Upon CLL diagnosis, physicians should determine whether treatment or careful observation is indicated. Once treatment is required, choice of therapy should be based on the age and fitness of the patient and the distinct molecular profile of their disease. As multiple novel agents are in various stages of development, all patients regardless of their age, fitness, and disease risk should be evaluated for clinical trial participation before initiating any front-line therapy...

BACKGROUND AND OBJECTIVE: The broad therapeutic arsenal and the biological heterogeneity of patients with chronic lymphocytic leukemia (CLL) makes it difficult to standardize treatment for CLL patients with specific clinical settings in routine clinical practice. These considerations prompted us to elaborate the present consensus document, which constitutes an update of the previous version published in 2013, mainly focusing on novel treatment strategies that have been developed over last 5 years, namely B-cell receptor inhibitors (ibrutinib and idelalisib), anti-CD20 monoclonal antibodies (ofatumumab and obinutuzumab), and Bcl-2 inhibitors (venetoclax)...

The recent past has brought pharmacotherapeutic advances that benefit patients with hematologic malignancies. In 2016, two novel hematology drugs were approved and four previously approved hematology drugs were granted expanded use for the treatment of appropriate patient populations by the US Food and Drug Administration. These new approvals and indications represent significant steps forward in patient management: they include the first-in-class B-cell lymphoma 2 inhibitor, venetoclax, the newest targeted therapy available for the treatment of hematologic malignancies; and nivolumab, the first immune checkpoint inhibitor to be approved for treatment of a hematologic malignancy...

A number of new treatment options have recently emerged for chronic lymphocytic leukemia (CLL) patients, including the Bruton's tyrosine kinase (BTK) inhibitor ibrutinib, phosphatidylinositol-3-kinase (PI3K) delta isoform inhibitor idelalisib combined with rituximab, the Bcl-2 antagonist venetoclax, and the new anti-CD20 antibodies obinutuzumab and ofatumumab. Most of these agents are already included into treatment algorithms defined by international practice guidelines, but more clinical investigations are needed to answer still remaining questions...

For decades, treatment of chronic lymphocytic leukemia (CLL) has been based on chemotherapy. This changed when the first CD20 antibody rituximab was introduced. Since 2008, the combination of chemotherapy and CD20 antibodies has become the standard of care for most patients, and a significant fraction of patients had very long-lasting remissions after chemoimmunotherapy. Despite the improvement of response rates and overall survival (OS) by the use of chemoimmunotherapy, most CLL patients will relapse eventually...

GA101, also known as obinutuzumab or Gazyva (Gazyvaro), is a glycoengineered type II humanized antibody that targets the CD20 antigen expressed at the surface of B-cells. This novel anti-CD20 antibody is currently assessed in clinical trials with promising results as a single agent or as part of therapeutic combinations for the treatment of B-cell malignancies. Detailed understanding of the mechanisms of GA101-induced cell death is needed to get insight into possible resistance mechanisms occurring in patients...

AIM: The Phase Ib GERSHWIN study (NCT01680991) assessed the pharmacokinetic (PK) profile of obinutuzumab following multiple intravenous (i.v.) doses to Chinese patients with B-cell lymphomas, and compared findings with previous obinutuzumab PK studies in mainly Caucasian (non-Chinese) patients. METHODS: GERSHWIN was an open-label, single-arm intervention study. Patients aged >18 years with CD20+ relapsed/refractory chronic lymphocytic leukaemia (CLL), diffuse large B-cell lymphoma (DLBCL) or follicular lymphoma (FL) were enrolled from four centres in China...

The GAUDI study assessed safety and preliminary efficacy of induction therapy with obinutuzumab plus chemotherapy, followed by maintenance with obinutuzumab alone, in previously untreated patients with follicular lymphoma. Assignment to chemotherapy was decided on a per center basis before patient enrollment. Patients (n=81) received 4-6 cycles of obinutuzumab plus bendamustine every 4 weeks or 6-8 cycles of obinutuzumab plus CHOP every 3 weeks. Patients with an end-of-treatment response were eligible for obinutuzumab maintenance therapy every 3 months for 2 years or until disease progression...

Obinutuzumab (GA101) is a novel, type II, glycoengineered, humanized anti-CD20 monoclonal antibody that has been developed to address the need for new therapeutics with improved efficacy in patients with lymphocytic leukemia and lymphoma of B-cell origin. Obinutuzumab has a distinct mode of action relative to type I anti-CD20 antibodies, such as rituximab, working primarily by inducing direct cell death and antibody-dependent cell-mediated cytotoxicity. Obinutuzumab is under investigation in a wide-ranging program of clinical trials in patients with B-cell malignancies...

It is an unprecedented time for the treatment of patients with chronic lymphocytic leukemia (CLL) with the recent approval of several targeted agents for use in frontline, relapsed, refractory, and high-risk disease. Traditionally, frontline management of CLL has been a combination of chemotherapy (fludarabine, cyclophosphamide, bendamustine, or chlorambucil) with an anti-CD20 monoclonal antibody (rituximab, ofatumumab, obinutuzumab). The current landscape is rapidly evolving with the advent of therapies that demonstrate selective inhibition of important pathways necessary for CLL proliferation and survival...

Anti-CD20 monoclonal antibodies (mAb) such as rituximab have been proven to be highly effective at improving outcome in B-cell malignancies. However, many patients ultimately relapse and become refractory to treatment. The glycoengineered anti-CD20 mAb obinutuzumab was developed to induce enhanced antibody-dependent cellular cytotoxicity, antibody-dependent phagocytosis and direct cell death and was shown to lead to improved outcomes in a randomized study in B-CLL. We hypothesized that immune stimulation through Toll-like receptor 7 (TLR7) agonism in combination with obinutuzumab would further enhance lymphoma clearance and the generation of long-term antitumor immune responses...

With the recent approval of several new targeted therapies for chronic lymphocytic leukemia (CLL), there are now multiple options for its treatment. Inhibitors of Bruton tyrosine kinase (with ibrutinib being the first-in-class US Food and Drug Administration-approved agent) and phosphoinositide 3-kinase (with idelalisib as the first-in-class approved agent) are promising because they are generally well tolerated and highly effective against this malignancy. These agents may be particularly important in the treatment of older patients who are less able to tolerate the myelosuppression (and subsequent infections) associated with chemoimmunotherapy...
