Target therapy in hematological malignances: new monoclonal antibodies.
In many cases of hematological malignancies the classical chemotherapy did not show the expected effects. For this reason the scientists have been trying to find a new, more selective therapy, which would target only neoplastic cells.
In 1997, for the very first time, a novel treatment was introduced. It was when the FDA approved rituximab, the first anti-CD20 monoclonal antibody (MoAb) [1-3]. It has had such a long lasting impact that you can now come across the term "rituximab era" in the medical literature. Today, targeted therapy, based on selective inhibition of molecules, is becoming increasingly popular .
MoAbs, used in hematooncology, are immunoglobulins, which selectively bind molecular targets and suppress carcinogenesis. The first MoAbs were derived from mice and provoked a strong immunological reaction when given to humans. The progress in genetic engineering allowed us to produce chimeric MoAbs, consisting of 60 up to 90% of human antigens. Chimeric MoAbs consist of human constant regions and mouse variable regions, responsible for the recognition of the antigen. Humanized antibodies contain up to 90% of human sequences. They are produced by merging highly variable mice regions, which are responsible for the specificity of the antibody, with human regions . MoAbs used in modern therapy are completely humanized and they contain only human amino acid sequences. MoAbs destroy neoplastic cells in three different ways. They can induce apoptosis and block growth factor receptors or modulate their ligand-receptor interaction. In order to reach high therapeutic goals, MoAbs are conjugated with radioisotopes, toxins, cytostatics, or cytokines .
This review will focus on three major aspects of monoclonal antibody therapy: (1) brief description of monoclonal antibodies used in hematooncology, (2) new therapeutic approaches to currently approved agents, and (3) preclinical and clinical experience with new agents in the last few years.
2. Monoclonal Antibodies Used in Hematology
Several studies in the fields of molecular biology, biochemistry, and genetics proved that there are a number of molecular signaling pathways and molecules, whose selective inhibition or modification leads to the elimination of the neoplastic cells. Currently, several MoAbs are FDA approved for the therapy of hematological diseases (Table 1). Their short description is presented below.
2.1. Rituximab. Rituximab has been approved for the treatment of non-Hodgkin's lymphoma (NHL) by the FDA in 1997. From that moment on a new era, called "rituximab era" began. Since that time, many other antibodies, whose target is the CD20 antigen, have been introduced. Currently, rituximab is widely used to treat a number of diseases caused by an abnormal production of B cells. It is approved by the FDA for the treatment of B-cell non-Hodgkin's lymphomas, including chronic lymphocytic leukemia (CLL) and rheumatoid arthritis . It is also used in the treatment of autoimmune hemolytic anemia, graft-versus-host disease, chronic immune-mediated thrombocytopenia, posttransplant lymphoproliferative disorder, pemphigus vulgaris, systemic lupus erythematosus, multiple sclerosis, and Evans Syndrome [5,6].
2.2. Ibritumomab. Ibritumomab is a murine IgG-1 kappa anti-CD20 antibody that is conjugated to yttrium-90 (pure beta emitter) or indium-111 (gamma emitter) in the presence of chelate tiuxetan (Mx-DTPA) [7, 8]. This monoclonal antibody binds to the CD20 antigen found on the surface of malignant and normal B cells. Radiation from the attached isotope kills malignant cells. Antibodies can also cause cell's death by antibody-dependent cell-mediated cytotoxicity (ADCC), complement-dependent cytotoxicity (CDC), and apoptosis.
The main indication for ibritumomab therapy is relapsed or refractory, low grade or follicular, B-cell NHL . In 2009 ibritumomab was also approved for consolidation therapy in patients with follicular lymphoma who achieved response to first-line chemotherapy. Contraindications for the use of ibritumomab include absolute neutrophil count lower than 1500 cells/[mm.sup.3] or platelet count lower than 100,000/[mm.sup.3] or effective beam radiation therapy of >25 percent of active marrow. It must not be used in patients who had prior autologous stem cell transplantation, during pregnancy or ongoing breastfeeding, and in patients with allergy or hypersensitivity to the murine antibodies or components of the therapy .
2.3. Ofatumumab. Ofatumumab is an IgG1 (kappa) fully human monoclonal antibody whose epitope on CD20 is distinct from rituximab's target and activates CDC more effectively. It induces cell lysis of both high and low CD20-expressing cells and of rituximab-resistant cells [6,10].
An initial phase I/II study of 33 patients with CLL who received 4, once weekly, infusions of ofatumumab showed a 50% overall response rate . Promising results encouraged researchers to continue the study in a larger group of patients. In 2008, during the conference of the American Society of Hematology, Wierda et al.  presented the results of a phase II clinical trial. The study group consisted of patients with relapsed CLL refractory to fludarabine and alemtuzumab (response rate 58%) or with bulky lymphadenopathy refractory to fludarabine (response rate 47%). Clinical improvement was achieved for several symptoms, such as lymphadenopathy, splenomegaly, and hematological parameters. Based on these results, the FDA and EMEA registered ofatumumab for the treatment of patients with CLL in 2010 [6, 11]. The recent study comprised 77 previously untreated patients, who were divided into two groups and received either 2000 mg or 1000 mg of ofatumumab as an induction therapy, once a week . Maintenance therapy was continued at the same dosage for a consecutive period from two months to two years. The overall response rate for the high doses group and the low doses group was 55% and 36%, respectively. Recently, there have been some reports about two studies in which ofatumumab was combined with lenalidomide, a drug that augments and sensitizes CLL cells to monoclonal antibody-induced cell death. In one of these studies 36 patients with CLL received ofatumumab once a week for 4 weeks, once a month during months 2-6, and every other month during months 7-24. Lenalidomide was administered on day 9 of every month of the treatment. The objective overall response rate in 34 evaluable patients was 68% and median duration of response was 22 months. The second phase of the study evaluated the efficacy of the same treatment regimen in high-risk patients. The therapy was well tolerated and the most common side effect was neutropenia [13,14].
Ofatumumab was also studied in patients with follicular lymphoma refractory to rituximab. Overall response rate was 10% for patients receiving the dose of 1000 mg of ofatumumab weekly and 13% for the group receiving the dose of 500 mg weekly. The most common side effects were infections, rash, urticaria, fatigue, and pruritus. Severe adverse events such as neutropenia, anemia, or thrombocytopenia were less common [15,16].
2.4. Tositumomab. This radioimmunopharmaceutical was introduced by the FDA in 2003. It is a murine IgG2a anti-CD20 antibody, which has been linked to radioactive iodine, and emits gamma radiation. It is characterized by a relatively long half-life of 193 hours. The maximum range in the healthy tissue for tositumomab is only 2.3 mm and for this reason its use as a myelosuppressive agent is limited . The underlying cause is the accumulation of antibodies which emit anti-gamma radiation in the tissue. Several studies have reported that in the group of patients previously treated with radioimmunoassay myelodysplastic syndromes are more frequent (2.5-3%) than in other groups, but it is difficult to clearly assess whether it is the effect of radioactive substances or chemotherapy. Tositumomab is concentrated in the thyroid gland and may cause its hypofunction. Administration of potassium iodide during the treatment can prevent this side effect. Compared with ibritumomab tiuxetan, the radiation dose accumulated in the liver is lower but the dose accumulated in kidneys is higher. The main indication for the treatment with tositumomab is refractory, CD20-positive, low-grade, follicular, or transformed NHL in patients refractory to rituximab treatment. In the group of previously untreated patients with low-grade lymphoma the response rate was 100% while the complete response rate was 56% [17-19].
2.5. Gemtuzumab. Gemtuzumab ozogamicin is an engineered humanized monoclonal IgG4 antibody directed against the CD33 antigen present on leukemic cells in 80% of patients with AML. In the group of patients responding to gemtuzumab >90% had very high CD33 antigen expression. This monoclonal antibody is linked to calicheamicin, which is a cytotoxic antibiotic attached to the antibody through a covalent linkage. Thanks to this condensation calicheamicin is stable in physiologic buffers and is efficiently released inside lysosomes [20, 21]. 40 patients with morphological evidence of leukemia in the bone marrow were treated with gemtuzumab in the phase I trial. After 1 to 3 doses 20% of these patients had <5% leukemic blast cells in the bone marrow .
Further multicenter trials, which comprised 142 patients with AML in first relapse, have shown that gemtuzumab was effective in thirty percent of the patients . Based on these pivotal studies, in 2000, gemtuzumab was registered by the FDA for the treatment of patients with CD33-positive AML in first relapse who were 60 years of age or older and who were not considered candidates for cytotoxic chemotherapy. Gemtuzumab can be also used in patients with relapsed acute promyelocytic leukemia. In this type of AML prolonged molecular remissions were obtained when gemtuzumab was used in monotherapy and when it was administered in combination with other drugs .
However, the next study, SWOG S0106, did not confirm the clinical benefits of using gemtuzumab in combination with daunorubicin and cytarabine. The most common adverse events in this trial, that is, infection, hemorrhage, and ARDS, were reported more frequently when gemtuzumab was used in combination with other drugs than in the monotherapy. A second phase III trial, evaluating the addition of gemtuzumab to induction and/or consolidation therapy in the first-line treatment, did not confirm the clinical benefits of gemtuzumab either. Based on these results, in October 2010, gemtuzumab was withdrawn from the US and European markets, but it is still available in Japan [23, 24].
The most common adverse reaction associated with the use of gemtuzumab was hepatic injury (the increased transaminases and bilirubin level). An increased incidence of venoocclusive disease (VOD) in the group of these patients was also reported. It is estimated that this type of complication after allo-HSCT was observed in 0-70% of cases, and the risk of these adverse events increases in the group of patients with liver damage, in which myeloablative chemotherapy or busulfan therapy was used . Thus, the use of this MoAb in clinical practice needs further investigation.
2.6. Brentuximab. Brentuximab is a chimeric IgG1 antibody that targets the cell membrane protein CD30, expressed on Hodgkin lymphoma cells and anaplastic large-cell lymphoma cells. It is linked through a peptide linker to the potent inhibitor of microtubule polymerization, monomethylauristatin E (MMAE) [26,27].
In phase I studies brentuximab was evaluated in a group of 45 patients with relapsed or refractory CD30-positive malignancies. The drug was administered in the doses ranging from 0.1 to 3.6 mg/kg given every 3 weeks by intravenous infusion. The adverse events depended on the treatment dose and the most common included fatigue, fever, diarrhea, nausea, neutropenia, and peripheral neuropathy, headache, vomiting, back pain, anemia, and alopecia. Tumor regression was reported for 83% of patients .
In phase II studies of brentuximab the group of 102 patients with relapsed or refractory Hodgkin lymphoma was analyzed. Patients were administered the dose of 1.8 mg/kg of this monoclonal antibody every three weeks. Seventy-five percent of these patients achieved an objective response. The results were reported at the 2011 Annual Meeting of the American Society of Clinical Oncology .
In April 2010, a double-blind, placebo-controlled, phase III study was initiated on patients with posttransplant Hodgkin lymphoma. This study is expected to be completed soon. On 14 July 2011, Food and Drug Administration approved brentuximab for the treatment of Hodgkin lymphoma relapsed after autologous stem cell transplantation and for the management of relapsed anaplastic large-cell lymphoma. The results of the phase III trial will form the basis for full FDA approval .
2.7. Alemtuzumab. Alemtuzumab is a humanized anti-CD52 monoclonal antibody, which is derived from the original rat antibody, Camppath-1 G . It is highly effective in the elimination of cells of the B- and T-lymphocyte lineages, both normal and malignant. Alemtuzumab might be given intravenously as well as subcutaneously. The injection often induces an immune response with clinical signs such as chills, fever, or erythema. These reactions are associated especially with the release of the cytokines: TNF-a, INF-y, and IL-6 .
Alemtuzumab is indicated in the therapy of CLL, T-cell prolymphocytic leukemia, cutaneous T-cell lymphoma, and peripheral T-cell lymphoma . Alemtuzumab is associated with viral (e.g., CMV or VZV) and fungal opportunistic infections. For this reason it is advisable to carefully assess each patient before the therapy is started . Alemtuzumab reduces the number of B- and T-lymphocytes, thus causing immunosuppression. Lymphopenia is sometimes profound and long-lasting; therefore, it is recommended to use anti-infective prophylaxis with cotrimoxazole and acyclovir for 6 months after completing alemtuzumab therapy .
The first clinical trials of alemtuzumab in patients with chronic lymphoid leukemia were performed in 1997. Further studies were carried out by Lundin et al. and they included a much bigger group of patients . In this group 33% of patients responded to alemtuzumab (lymphocyte count decreased rapidly), but significant decrease in lymphadenopathy was observed in only 7% of them .
A phase II clinical trial examined the efficiency of alemtuzumab given subcutaneously in relapse patients with progressive form of CLL. The response rate was 87%, including 19% of complete remissions. The FDA approved alemtuzumab for the treatment of CLL in patients with resistance to fludarabine and alkylating agent therapy .
3. Monoclonal Antibodies Used in
Clinical Trials or Preclinical Development
Currently, many MoAbs are being studied in clinical trials and their use in the treatment of hematological diseases still develops. The aim of this review article is to describe only the most important of them. Table 2 presents their short description.
3.1. Apolizumab. Apolizumab (Hu1D10), a humanized monoclonal anti-human leukocyte antigen- (HLA-) DR betachain antibody, is currently studied in clinical trials for hematologic malignancies . The HLA-DR antigen is selectively expressed on immune cells, such as lymphocytes, monocytes, and dendritic cells . Hu1D10 induces complement-mediated cytotoxicity, antibody-dependent cell-mediated cytotoxicity , and caspase-independent apoptosis following secondary cross-linking in CLL cells . Preclinical and early clinical studies suggest that apolizumab has some activity in CLL and NHL patients with acceptable toxicity profiles [36, 37]. It can be safely administered as a slow intravenous infusion but it causes severe toxicity in animal models when given as a bolus . Granulocyte colonystimulating factor (G-CSF) treatment significantly enhanced lymphoma cell killing by HLA class II antibodies, including apolizumab . Another study assessed the effects of apolizumab in combination with rituximab in patients with relapsed/refractory NHL. Preliminary results of this phase I clinical trial suggest that this combination may be more effective than rituximab alone .
3.2. Milatuzumab. Milatuzumab is a new humanized antibody which targets tumors with CD74 antigen, expressed on monocytes, macrophages, and B cells but not on T cells . It has recently been shown that binding of milatuzumab to the CD74 antigen on human peripheral B-cell subsets causes a number of effects, including inhibition of proliferation, enhanced spontaneous migration, alterations of adhesion molecule expression, and CXCL12-dependent chemotaxis of B cells [41, 42]. These biological functions combined with the expression of CD74 on malignant B cells and limited expression on normal tissues implicate CD74 as a potential therapeutic target . Milatuzumab is the first anti-CD74 antibody that has entered into clinical tests and is currently being studied for the treatment of NHL, CLL, and multiple myeloma (MM) [43-45]. Broad expression and fast internalization make CD74 an ideal target for the delivery of chemotherapeutic agent against CD74-expressed tumors [46, 47]. Milatuzumab, as a doxorubicin conjugate, is currently in a phase I/II clinical trial for the treatment of patients with relapsed MM and in combination with rituximab represents a potential therapeutic strategy for the treatment of mantle cell lymphoma (MCL) patients [48, 49]. Another preclinical study shows that milatuzumab can enhance the therapeutic efficacy of bortezomib, doxorubicin, and dexamethasone in MM cell lines . There is possible synergy in action between milatuzumab and another MoAb--veltuzumab . The ongoing trials testing different doses and treatment schedules of milatuzumab in CLL, NHL, and MM showed no severe adverse effects in humans .
3.3. Monoclonal Antibodies against CD22 Antigen: Inotuzumab and Epratuzumab. The antigen CD22 is a transmembrane glycoprotein expressed on mature B cells and on up to 90% of B malignant cells . Its function is unclear; however, recent studies suggest that it regulates B-cell functions, has an impact on their survival, and serves as an adhesion molecule . Therefore, CD22 is a candidate target for therapeutic antibodies. In this review we will focus on two novel anti-CD22 MoAbs, inotuzumab and epratuzumab, which are currently under investigation in B-cell malignancies.
Inotuzumab ozogamicin (CMC-544) is an antibody-drug conjugate composed of a humanized anti-CD22 antibody linked to calicheamicin, a potent cytotoxic agent . This linkage enables direct intracellular delivery of the chemotherapeutic agent, which reduces toxicity and normal tissue exposure . CD22 binding causes rapid drug internalization and results in DNA damage and cellular apoptosis 56].
Clinical trials revealed inotuzumab ozogamicin activity in the treatment of B-cell NHL, including follicular lymphoma and diffuse large B-cell lymphoma (DLBCL), in patients who failed prior therapies . It was effective in monotherapy, while combination with rituximab increased its antitumor activity . Moreover, some studies suggest that inotuzumab ozogamicin successfully induces remission in patients with relapsed acute lymphoblastic leukemia allowing more patients to receive stem cell transplant (SCT) [56, 59-61]. The most frequently described adverse events in inotuzumab ozogamicin treatment were thrombocytopenia, neutropenia, and hepatotoxicity [22, 62]. Combination with rituximab did not significantly change drug safety profile .
Epratuzumab is another humanized anti-CD22 MoAb. Similarly to inotuzumab it demonstrated the activity in B-cell NHL patients who have relapsed or are refractive to conventional therapy, including rituximab . Epratuzumab has been evaluated as a single agent or in combination with rituximab or standard chemotherapy . Several studies revealed that combination of epratuzumab and rituximab in NHL patients enhances clinical efficacy and was better tolerated than rituximab alone [66, 67]. Therefore, bispecific MoAbs consisting of veltuzumab (humanized anti-CD20) and epratuzumab (humanized anti-CD22) were constructed and evaluated . A promising pilot study described chemotherapy based on epratuzumab with rituximab, cyclophosphamide, doxorubicin, vincristine, and prednisone (R-CHOP) in untreated DLBCL . Epratuzumab has antilymphoma activity in both, unlabeled and radiolabeled, forms. Recently the phase I/II trials with fractionated radiolabeled anti-CD22 MoAb have been published and they showed high rates of durable CR in recurrent and heavily pretreated NHL patients . Moreover, the drug is currently under investigation as a novel targeted therapy in acute lymphoblastic leukemia (ALL) and autoimmune diseases such as systemic lupus erythematosus and primary Sjogren's syndrome [71-73]. Some data demonstrate that this agent has good safety profile without dose-dependent toxicity .
No drug interaction has yet been reported with epratuzumab . Infusion-connected toxicity appears to be less intense than for rituximab . Because epratuzumab has a different effect on cell growth in comparison to rituximab it may become an important component of the future therapies for NHL.
3.4. Obinutuzumab. Obinutuzumab (GA101) is a glycoengineered, IgG1, anti-CD20 monoclonal antibody that is classified as type II MoAb [77, 78]. It induces cell death through caspase-independent way and has shown lower levels of CDC . In phase I/II trials obinutuzumab was evaluated as a monotherapy in 12 patients with malignant diseases with CD20 expression. The complete response was obtained in 25% of patients and partial response in 33% of them [77, 79].
Obinutuzumab and chlorambucil combination is now evaluated in a phase III study of patients with previously untreated CLL. It is estimated that the study will be completed in February 2022 [77, 79]. Another study is assessing obinutuzumab and bendamustine combination therapy in patients with rituximab-refractory indolent NHL. Perhaps this study will be completed in January 2015 .
Obinutuzumab or rituximab and chlorambucil combination was evaluated in a phase III study of patients with previously untreated CLL. This study compared the effectiveness of chlorambucil monotherapy with combination therapy of rituximab with chlorambucil and obinutuzumab with chlorambucil. It has been shown that patients who used combination therapy achieved a longer disease-free period (26.7 versus 11.1 months) and a higher percentage of complete response to treatment. The application of obinutuzumab and chlorambucil compared with rituximab and chlorambucil resulted in a prolongation of progression-free survival and the number of overall responses (20.7% versus 7%) and molecular responses. The infusion-related reactions and neutropenia during obinutuzumab therapy were observed more frequently. Nevertheless the increased risk of infection was not shown .
3.5. Veltuzumab. Veltuzumab (HA20) is a humanized type I, IgG1, anti-CD20 MoAb constructed on the framework regions of epratuzumab. It has a stronger impact on CDC than rituximab but has shorter infusion time . In the clinical trial phase I/II study veltuzumab was administered to a group of 82 patients with relapsed/refractory B-cell NHL. MoAb was administered intravenously at the doses of 80-750mg/[m.sup.2], once weekly for four doses. As many as 27% of patients obtained complete response, and the median time of response was 19.7 months [6,82]. Other studies have reported on the effectiveness of the subcutaneous injections of low doses (80-320 mg): this route of administration seems to be as good as the intravenous one . Further research is carried out on the use of this antibody in the treatment.
3.6. Ocrelizumab. Ocrelizumab is a type I, second generation, chimeric, IgG1, anti-CD20 monoclonal antibody, which mediates cell lysis by apoptosis, antibody-dependent cellular cytotoxicity, and complement-dependent cytotoxicity [6, 83, 84]. It is characterized by increased binding affinity for the low-affinity variants of the FcyRIIIa receptor; therefore it may have greater clinical efficacy in the 80%-85% of patients who are carriers of the low-affinity variants . In trial phase I/II study it was tested in forty-seven patients with relapsed follicular lymphoma after prior rituximab therapy. The single-agent therapy with ocrelizumab resulted in 38% overall response rate [83, 85]. The incidence of infusion-related adverse events was very low. The grade 3/4 toxicity was observed only in 9% of patients, but infusion-related reactions were much more frequent and were observed in 74% of the analyzed patients [6, 85].
3.7. Lumiliximab. Lumiliximab is a chimeric monoclonal antibody directed against CD23 antigen, which is highly expressed on CLL cells but only minimally on other cells . Lumiliximab induces apoptosis by activating caspases and downregulating antiapoptotic proteins . It has been investigated as a monotherapy or in combination with rituximab or other chemotherapeutic agents in relapsed or refractory CL.
Clinical data from a phase I dose-escalation trial with lumiliximab monotherapy in pretreated CLL patients demonstrated acceptable toxicity profile when the drug was given 3 times per week for 4 weeks at doses of up to 500 mg/[m.sup.2] . A phase I/II multicenter study revealed synergy of lumiliximab with fludarabine, cyclophosphamide, and rituximab (L + FCR) therapy in the above-mentioned group. The addition of lumiliximab enhanced therapeutic effect of FCR treatment and resulted in high overall response rate and complete remission rate (65%, 52%, resp.). Combination of these drugs showed no additional toxicity . CD23 glycoprotein, as a receptor for IgE, is involved in the regulation of IgE-mediated inflammatory process. Preliminary studies suggested that lumiliximab might provide clinical benefit in patients with persistent allergic asthma and other allergic diseases [90, 91]. The phase III study comparing FCR and FCR plus lumiliximab in relapsed CLL did not confirm the beneficial effects of this combination .
3.8. Galiximab. Galiximab, anti-CD80 chimeric MoAb, represents a new therapeutic approach to NHL patients. CD80 is a costimulatory molecule involved in T-cell activation . Surface CD80 is transiently expressed on antigen-presenting cells and normal B cells and constitutively expressed on a variety of B-cell lymphomas . After CD80 activation cell death via antibody-dependent cell-mediated cytotoxicity (ADCC) was induced . Moreover, galiximab inhibits tumor cell proliferation through influence on intracellular pathways such as NF-[kappa]B pathway . Preclinical studies revealed its significant antitumor activity as a single agent or in combination with rituximab against various B-cell lymphoma cell lines including follicular lymphoma . Despite being well tolerated, galiximab had minimal activity in pretreated patients with relapsed Hodgkin lymphoma (HL) . Phase I/II monotherapy trial of galiximab in relapsed/refractory follicular lymphoma revealed its efficacy and safety profile. The overall response rate was 11% and the most commonly observed adverse events were fatigue, nausea, and headache. Cytopenia occurred rarely . Galiximab showed some promising results when used in combination with rituximab. Phase II trial of galiximab plus rituximab (CALGB trial) in untreated follicular lymphoma showed that the ORR was 72.1% including a 47.6% CR rate . Due to its immunomodulatory properties, galiximab was evaluated as a potential novel therapy for psoriasis .
3.9. Lintuzumab. Lintuzumab is a humanized monoclonal antibody which targets CD33 molecule. It has been under investigation as a treatment option for myeloid malignancies in patients who do not qualify for intensive chemotherapy or bone marrow transplantation. Lintuzumab, as a single agent, presents minimal antileukemic activity in patients with relapsed/refractory acute myelogenous leukemia (AML) and more significant activity against minimal residual disease in acute promyelocytic leukemia (APL) . The efficacy of lintuzumab was evaluated in combination with induction chemotherapy in relapsed or primary refractory AML. Although the addition of lintuzumab was safe, it did not significantly improve survival rate . A phase II randomized clinical study of lintuzumab in combination with a low dose of cytarabine in elderly adults with untreated AML presented similar results . Recently, it has been reported that 5-azacytidine enhances its mediated effector functions in vitro and induces antitumor effects in vivo . These findings required further clinical investigation. To increase drug potency lintuzumab was conjugated to radionuclides as, for example, actinium ([sup.225]Ac), bismuth ([sup.231]Bi), or iodine (I-131), with promising results in AML patients [105-107]. Moreover, lintuzumab conjugated with immunotoxin recombinant gelonin (HUM-195/rGEL) has been under investigation in patients with relapsed/refractory myeloid leukemias .
3.10. Monoclonal Antibodies against CD40 Antigen: Dacetuzumab and Lucatumumab. Dacetuzumab is a new humanized anti-CD40 monoclonal antibody in early phase of clinical trials. The CD40 protein is a member of the TNF-receptor superfamily highly expressed on normal B cells . The CD40 signaling may play a role in the development of B-cell hematological malignancies; therefore anti-CD40 MoAb is an attractive option for targeted therapy . Dacetuzumab has been reported to induce antitumor activity against several B-cell lymphomas and MM cell lines in vitro . Dacetuzumab as a monotherapy in NHL patients was well tolerated (doses up to 8mg/kg/wk) without dose-limiting toxicity . The observed safety profile suggested that combination of dacetuzumab with other chemotherapeutic agents may improve its clinical effectiveness. Preclinical studies revealed synergistic activity between dacetuzumab, gemcitabine, and rituximab in NHL . The combination of dacetuzumab with lenalidomide in MM cells in vitro had synergic effect as well . Moreover, dacetuzumab demonstrated activity that is enhanced by lenalidomide in CLL . Many of these combinations are now being tested clinically. A phase I safety/efficacy study of dacetuzumab in combination with rituximab and gemcitabine was conducted in relapsed/refractory diffuse large B-cell lymphoma (DLBCL) . Two trials are ongoing in patients with relapsed MM to evaluate dacetuzumab in combination with lenalidomide or bortezomib [116,117].
Lucatumumab is another humanized monoclonal antibody targeting CD40 protein. The drug has two distinct mechanisms of anticancer activity. It blocks the interaction between CD40 and its ligand on malignant cells and it mediates antibody-dependent cell toxicity (ADCC) . In preclinical testing lucatumumab showed antilymphoma activity in vivo and decrease in proliferation of B cells in vitro . It has been already clinically evaluated for treatment of various hematological malignancies. In patients with relapsed CLL tolerability of lucatumumab was acceptable but it had only minimal activity as a single agent . Similarly, in patients with relapsed or refractory MM lucatumumab displayed modest clinical activity . Those findings resulted in subsequent studies of lucatumumab as a combination therapy. Lucatumumab plus bendamustine has been in phase I/II trial for follicular lymphoma patients . Moreover, clinical efficiency of the drug is currently under investigation in patients with relapsed/refractory HL or NHL . In June 2014 the report concerning its effects in the treatment of NHL and HL appeared, which were a continuation of the phase Ia/II study . Patients with diagnosed lymphoma were administered lucatumumab intravenously once a week for 4 weeks of an 8-week cycle. Response was assessed separately for the different subtypes of lymphoma. The overall response rate assessed by computed tomography among patients with marginal zone lymphoma of mucosa-associated lymphatic tissue (MZL/MALT) was 42.9% but, with follicular lymphoma (FL), was 33.3%. Future efforts with lucatumumab should focus on combination-based therapy. Clinical trials on the use of lucatumumab in the treatment of CLL or MM are not conducted further .
3.11. Blinatumomab. Blinatumomab is the first of the bispecific T-cell engagers (BiTE) antibodies--a new group of agents combining targeted therapy with immunologic activation of T cells, which exert cytotoxic activity on the target cells . Blinatumomab has dual specificity for CD19 and CD3. It links T cells to target cells expressing CD19, a protein found on the majority of B-cell malignancies, causing redirected lysis of tumor cell [126, 127]. The effects of blinatumomab have been evaluated in preclinical studies. Blinatumomab compared with rituximab showed higher degree of lysis of human lymphoma lines and the combination of both drugs enhanced the antitumour activity of blinatumomab . Blinatumomab has received orphan drug designation from the Food and Drug Administration (FDA) and is currently being investigated for the treatment of relapsed/refractory B-cell ALL and relapsed NHLs . Phase II study evaluating the efficacy and safety of blinatumomab in adult patients with ALL showed high rate of complete responses which was 72%. The most common adverse events were pyrexia, headache, tremor, and fatigue. These adverse events occurred most often at the onset of the treatment, during the first course . Blinatumomab was described as effective and well tolerated in patients with minimal residual disease positive- (MRD-) ALL and induced an 80% MRD eradication rate . A long-term follow-up revealed that the hematologic relapse-free survival was 61% of the entire evaluable study cohort . Already published data are based on clinical trials with ALL adults. Recently, multicenter study with blinatumomab in children has been initiated to evaluate the safety profile in all pediatric age subsets .
3.12. Bevacizumab. Bevacizumab is a humanized monoclonal antibody against vascular endothelial growth factor (VEGF) with a potential to reduce tumor angiogenesis and inhibit tumor growth . So far, the drug has been FDA-approved as a single agent and with combination with chemotherapy for the use in patients with several types of solid tumors, such as colorectal cancer, breast cancer, non-small cell lung cancer, renal cell cancer, and glioblastoma . However, it was shown that cardiovascular toxicity increases especially during combination therapy. Balancing the risks and benefits of bevacizumab requires understanding the spectrum of bevacizumab toxicities and predisposing factors . Bevacizumab has been recently introduced to hematology and its therapeutic effect has been demonstrated in AML, NHL, and HL [136-138]. There is evidence that angiogenesis may be a target in certain lymphoproliferative disorders. Increased VEGF expression has been found in many types of tumors, including NHL [139, 140]. Additionally, elevated VEGF level is associated with adverse prognosis in leukemia and lymphoma patients [141, 142]. Efficacy and safety of bevacizumab in distinct hematological malignancies are still uncertain and require further investigation. Bevacizumab as a single agent has been reported to have modest clinical activity in patients with relapsed aggressive NHL . Clinical trial of standard RCHOP therapy with bevacizumab in patients with untreated DLBCL showed that the combination was safe and well tolerated . However, for patients with newly diagnosed DLBCL the combination of drugs did not significantly prolong progression-free survival and resulted in increased serious toxicities . Bevacizumab in combination with standard (3 + 7) chemotherapy has been also evaluated in elderly patients with AML, but it did not improve the therapeutic outcomes . On the other hand, cytotoxic chemotherapy with cytarabine and mitoxantrone followed by bevacizumab revealed a favorable CR rate and its duration in adults with AML resistant to traditional treatment . Moreover, bevacizumab is currently under investigation as a treatment option for newly diagnosed AML in combination with idarubicin and cytarabine . In vivo and in vitro studies showed that bevacizumab has an ability to enhance the chemotherapeutic effect on T-leukemia/lymphoma cells [146,147]. In the case of HL, bevacizumab caused biological effects, which indicate it is clinically active .
For many years, MoAbs have been a well-known and constantly improved option for the targeted therapy of many hematological diseases. In recent years, technological progress allowed construction of MoAbs other than their classical forms: for example, conjugated with radionucleotides, immunotoxins, or bispecific antibodies. The new studies provide us with more and more encouraging results that open up new prospects for the usage of monoclonal antibodies in clinical practice.
