Genome agnostic, multi-level non-oncogene addiction-based systems pharmacology for rescuing metastatic relapsed/refractory neoplasias.

Rescue therapies for relapsed/refractory (r/r) metastatic neoplasias present significant unmet needs. Tumor tissue editing regimen for 13 r/r tumor types, carcinomas, sarcomas and hematologic neoplasias, included in 15 phase I/II trials, nuclear/cytokine receptor agonists, pioglitazone, plus/minus dexamethasone or all-trans retinoic acid or interferon-α to counterbalance tumor tissue homeostasis and reprogramming of cancer hallmarks, stress response inhibitors, COX-2 inhibitor, everolimus, lenalidomide, or clarithromycin, and a stress response inducer, low-dose metronomic chemotherapy with treosulfan, trofosfamide, capecitabine, or azacitidine. CR in three, cCR in another five r/r neoplasias, as the best response occurred after transcriptional reprogramming of cancer hallmarks, inflammation control or differentiation induction. Receptor agonist combinations for cCR induction can be identical among quite different tumor types and diversified within the same tumor histology. Data reveal ubiquitous, differential transcriptional access to non-oncogene addiction (NOA) networks that cope with cancer hallmarks/stress responses and three levels of therapeutic NOA targeting. (1) Agonists of nuclear/cytokine receptor NOAs critically target tumor identity and viability, while (2) transcriptional reprogramming of NOA networks that contribute to tumor tissue addiction, thereby genome-agnostically counteracting oncogene addictions. (3) Targeting edited NOAs may improve long-term outcome with CR/cCR (everolimus, IMiD). Transcriptionally accessible NOA targets offer high specificity, modest toxicity profile, low cost of therapy and outpatient treatment, independent of comorbidities. Adaptive targeting of the transcriptomic landscapes of tumor cell compartments breaks tumor tissue addiction and overcomes M-CRAC, post-therapy metastasis, cancer cell recolonization, acquired resistance and genetic heterogeneity. Thus, editing approaches provide a template for controlling metastatic r/r tumors. In the future, diagnostics of NOA networks and transcription factors involved in tumor tissue addiction may be as valuable for therapy selection as histological/molecular genetic tumor typing for the establishment of personalized hematology/oncology.

New approaches to treatment for multiple myeloma: durable remission and quality of life as primary goals.

New treatment approaches are changing the traditional paradigm for myeloma management. Partial or complete response with first-line therapy is now highly attainable. The focus of attention has thus shifted to obtaining the most durable remissions with the highest quality of life. A critical open question is whether more arduous and toxic therapies are justified with the intent to seek a cure. Patients with minimal symptoms at diagnosis are particularly reluctant to pursue aggressive strategies without documented long-term benefit. Conversely, patients with poor-risk molecular features, such as 13q deletion or t(4;14) translocation, can hopefully benefit from novel targeted therapies. New combinations incorporating bortezomib, thalidomide, and/or lenalidomide plus other novel agents offer the opportunity to explore therapy that is more effective and less toxic than in the past. The efficacy of single and tandem transplantation, which have documented long-term survival benefit, need to be compared with regimens integrating novel therapies. Whether true complete remission is a prerequisite for substantially improved survival is a central question in the framework of planned trials. The ultimate goal is to achieve clinical response (complete or partial) that offers the best quality remission for the longest period. Ideally, more effective induction and/or consolidation treatments will avoid concomitant toxicities and the need for maintenance therapies. Fortunately, new agents already offer longer-term disease control. The ongoing search for a cure will undoubtedly demand courage and dedication on the part of investigators and patients.

Emerging role of novel combinations for induction therapy in multiple myeloma.

Although multiple myeloma (MM) remains an incurable disease, there has been a concerted effort toward understanding its molecular pathogenesis, which has paved the way for the development of highly effective, novel therapeutic agents such as the immunomodulatory agents thalidomide and lenalidomide, and the proteasome inhibitor bortezomib. A better understanding of the molecular basis of chemotherapy resistance and the molecular sequelae of conventional cytotoxic and novel agents on MM cells and the bone marrow microenvironment has afforded the opportunity to study novel, rationally designed combination therapies in the clinic. These regimens have shown impressive activity in relapsed/refractory MM, and recent work has demonstrated unprecedented response rates in the first-line setting rivaling those seen with autologous stem cell transplantation. Recently presented results of 2 phase III clinical trials comparing melphalan/prednisone (MP) with MP and thalidomide (MP-Thal) in older patients with newly diagnosed MM have demonstrated superior progression-free survival and overall survival rates with MP-Thal, thus providing the first evidence that the improved response rates to these novel combination regimens will translate into better patient outcomes. Herein we review the early promising clinical activity of these regimens in patients with newly diagnosed MM.

Systemic immunoglobulin light-chain amyloidosis.

Amyloidosis is a rare disease in which amyloid fibrils compromise organ function and lead to death. Systemic immunoglobulin light-chain amyloidosis, usually caused by free light chains (FLCs) made by clonal plasma cells, is the most frequent type. Hereditary and senile systemic amyloidosis are less frequent types. Rarely, a patient with a tissue diagnosis of amyloidosis might have a monoclonal gammopathy and a hereditary protein. In systemic immunoglobulin light-chain amyloidosis, circulating clonal light chains can be measured with the FLC assay and provide a target for therapy aimed at eliminating the underlying plasma cell disorder while supporting the patient. Elimination of the pathologic FLC can lead to resorption of amyloid deposits and improvement in organ function. Monthly oral melphalan and dexamethasone for 1 year is effective therapy for patients not eligible for autologous stem cell transplantation (SCT) but carries a risk of myelodysplasia. For patients with limited organ involvement, SCT is an effective approach and, when followed after SCT by adjuvant thalidomide and dexamethasone for persistent plasma cell disease, achieves a high 1-year hematologic response rate. Complete hematologic responses can be durable beyond a decade and are usually associated with organ recovery. New agents, such as bortezomib and lenalidomide, have shown promising activity, and novel monoclonal antibody approaches are also under active investigation.

New directions in the treatment of mantle cell lymphoma: an overview.

Mantle cell lymphoma (MCL) is one of the most challenging lymphomas to treat. In the first-line setting, high-dose therapy (HDT) and autologous stem cell transplantation or hyperCVAD/rituximab suggest benefit, especially in patients aged < 60 years. Nucleoside analogue-based regimens represent an alternate option in patients ineligible for HDT. Fludarabine in combination with cyclophosphamide or mitoxantrone has shown activity, and the results were superior with the addition of rituximab. Other cytotoxic agents, such as cladribine, clofarabine, or bendamustin, showed promising activity as well. A variety of new monoclonal antibody (MoAb) agents, such as humanized anti-CD20, alemtuzumab, anti-HLA-DR, anti-CD22 (as an immunotoxin carrier), anti-CD40, as well as MoAb-targeting TRAIL-R1 and TRAIL-R2 are being tested. Radioimmunotherapy with Yttrium 90-ibritumomab tiuxetan and Iodine 131 tositumomab have been tested alone or in combination with chemotherapy, including as part of HDT and autologous stem cell transplantation, in which they showed the best results. New vaccine modalities are exploring the use of tumor cell-based vaccines or of agents that block or activate costimulatory pathways/molecules, such as CTLA-4-Ig. Allogenic transplantation represents a potential curative option for MCL, especially nonmyeloablative transplantation, more feasible in that population. A plethora of novel biologic agents have surfaced, such as bortezomib, temsirolimus, thalidomide, lenalidomide, MoAb anti-vascular endothelial growth factor or vascular endothelial growth factor-Trap, and flavopiridol. Other targets include gene transcription through histone regulation; nuclear factor-ķB pathway; protein kinase C inhibitors; small-molecules targeting apoptosis, such as antisense Bcl-2, pan-Bcl-2 family member inhibitors; MoAb agonists of cell death receptors; caspases regulators (inhibitors of apoptosis proteins, survivin); and MDM2 antagonist regulators of p53. A molecular approach to define biomarkers might help identify subgroups of patients and help develop rational therapies.

Multiple myeloma: diagnosis and treatment.

Major advances have occurred in our understanding of the biology of multiple myeloma (MM) and in its treatment in the past decade. New diagnostic criteria have been developed, and an international Staging System has replaced the Durle-Salmon Staging System. It is now possible to classify MM as standard risk or high risk on the basis of specific Independent prognostic factors. The role of single and double autologous stem cell transplantation has been clarified by randomized trials. Most importantly, thalidomide, bortezomib, and lenalidomide have emerged as new active agents and are being incorporated rapidly into the treatment of both newly diagnosed and relapsed MM. The current approach to the diagnosis, prognosis, and management of MM is reviewed.

The myelodysplastic syndromes: diagnosis and treatment.

The myelodysplastic syndromes (MDSs) are common, acquired, clinically challenging hematologic conditions that are characterized by bone marrow failure and a risk of progression to acute leukemia. These disorders can arise de novo, especially in elderly patients or, less often, as a consequence of prior chemotherapy or radiotherapy for an unrelated disease. The MDS classification systems were revised recently and updated. These refined classification and prognostic schemes help stratify patients by their risk of leukemia progression and death; this knowledge can help clinicians select appropriate therapy. Although many treatments for MDS have been proposed and evaluated, at present, only hematopoietic stem cell transplantation offers any real hope for cure, and no available therapy beyond general supportive care offers benefit to more than a minority of patients. However, recent clinical trials enrolling patients with MDS have reported encouraging results with use of newer drugs, including lenalidomide, decitabine, and darbepoetin alfa. Other exciting treatment regimens are being tested. Here, we present a contemporary, practical clinical approach to the diagnosis and risk-stratified treatment of MDS. We review when to suspect MDS, detail how to evaluate patients who may have a form of the condition, explain key features of treatments that are currently available in the United States, and summarize a general, common-sense therapeutic approach to patients with MDS.

Developmental therapeutics for myelodysplastic syndromes.

The management strategy for patients with myelodysplastic syndromes (MDS) has evolved from sole reliance on supportive measures to active treatment guided by disease risks. Recent progress in understanding the molecular pathogenesis of MDS has accelerated the discovery of new therapeutic targets, and consequently launched the development of several novel therapeutics that are currently in varied stages of clinical testing. One such agent is lenalidomide, which has shown remarkable effectiveness in the cytogenetically defined subset of MDS with the chromosome 5q31 deletion. The advent of new and effective targeted therapeutics may beneficially affect outcomes of an ever-increasing number of patients with MDS. This discussion summarizes the preliminary results of selected novel therapeutics.

Translational research in myelodysplastic syndromes.

The myelodysplastic syndromes (MDS) are receiving unusual attention recently as great strides have been made in understanding the biology. Recognition that excessive cytokine-induced apoptosis plays a significant role in the cytopenias of the majority of patients opened the doors to anti-cytokine therapy, with thalidomide being used with success in approximately 20% patients. Other therapies that have emerged include the thalidomide analog lenalidomide which is particularly beneficial for 5q- patients as well as a subset of non-5q- patients with low or intermediate-1 risk MDS. Other targeted therapies include vitamins, agents that are cytoprotective, differentiation inducers, anti-angiogenic, or immune modulatory. In addition, inhibitors of proteasome, methylation, histone deacetylation, farnesylation, receptor tyrosine kinases, topoisomerase, and matrix mettaloproteinases have yielded encouraging responses in subsets of patients. Specific therapies have also been developed for genetic abnormalities that lead to fusion genes (TEL-PDGFR-beta, or FIP1L1-PDGFR-alpha), or abnormal proteins due to mutations/functional inactivation (FLT3), dysregulated expression (EVI-1). In a short span of ten years, the field has evolved from having no effective therapy to offer the majority of MDS patients save chemotherapy, to having one FDA approved drug, several on the way to approval, and a number of novel agents producing exciting clinical results. This chapter summarizes the novel targets and targeted therapies in the rapidly evolving therapeutic landscape of MDS.

Cytokine targets in the treatment of myelodysplastic syndromes.

Myelodysplastic syndromes (MDS) are characterized by refractory cytopenias due to ineffective hematopoiesis in the marrow. Cytokines play an important role in the regulation of hematopoiesis; dysregulation of their levels can lead to hematopoietic failure. Considerable evidence implicates tumor necrosis factor alpha, transforming growth factor beta, interferons, interleukin 1beta, vascular endothelial growth factor (VEGF), and other inhibitory cytokines in the pathogenesis of MDS. These cytokines are produced by the interactions between the MDS clone and the bone marrow microenvironment. Therapeutic strategies therefore may augment the action of stimulatory growth factors or disrupt the effects of myelosuppressive cytokines. Erythropoietin alone and in combination with low-dose granulocyte colony-stimulating factor can lead to erythroid responses in selected patients. Agents targeting inhibitory cytokines include thalidomide, lenalidomide, etanercept, infliximab, VEGF receptor inhibitor PTK-787, antithymocyte globulin, and SCIO-469, a p38 mitogen-activated protein kinase inhibitor. Given the biologic heterogeneity of MDS, no single treatment is effective for all patients with the disease. With more detailed knowledge of cytokine signaling cascades, coupled with technological improvements in genomics and proteomics, the future treatment of this challenging disease may lie in combination therapies customized for relevant biologic effectors.

[New treatment strategy of multiple myeloma for cure].

Multiple myeloma has long been considered an incurable disease. Indeed, the median survival time in patients treated with conventional chemotherapy has been reported to be about 3 years, and the survival rate decreased consecutively and was about 2 to 3% at 10 years. However, after introduction of autologous stem-cell transplantation in the 1990s, the median survival time was improved to about 5 years. Furthermore, novel drugs have been introduced in the treatment of patients with relapsed/refractory multiple myeloma, and improved the prognosis of these patients. Thalidomide, which has anti-angiogenetic activity, has a 30-40% response rate, and the combination of thalidomide and dexamethasone has a 40-50% response rate. Lenalidomide, which is a thalidomide analog, has a higher efficacy and lower incidence of adverse effects than thalidomide. Bortezomib, which is a proteasome inhibitor and inhibits NF-kappaB activity, has also excellent efficacy like thalidomide. The clinical trials using these drugs for newly diagnosed patients are now ongoing around the world, and show very excellent results. The good combination of stem-cell transplantation and novel drugs may well improve the prognosis of patients with multiple myeloma, and induce a cure,especially in young patients.

Optimizing the efficacy and safety of bortezomib in relapsed multiple myeloma.

Bortezomib (Velcade, Millennium) is the first proteasome inhibitor to be used in clinical practice and is indicated for the treatment of multiple myeloma patients who have received at least one prior therapy. Bortezomib inhibits the intracellular degradation of proteins necessary for normal cell cycling and function. This, in turn, results in cell-cycle arrest and apoptosis. Bortezomib has shown significant activity in trials of patients with relapsed or refractory multiple myeloma; approximately one third of patients have shown significant improvement with bortezomib monotherapy in phase II and III clinical trials. Early phase trials are also evaluating bortezomib in combination with other agents used in the treatment of multiple myeloma, including melphalan, prednisone, thalidomide, and lenalidomide. Preliminary data suggest that bortezomib may act synergistically with some agents, and improves response rates. Bortezomib is generally well tolerated, but common side effects include peripheral neuropathy and thrombocytopenia. Studies are underway to explore different dosing strategies as well as ways to maximize patient benefit while reducing toxicity. This review will discuss what is known thus far about the efficacy and safety profile of bortezomib, ways for optimizing treatment with bortezomib, and strategies for managing side effects and enhancing quality of life.

Novel agents for the management of myelodysplastic syndromes.

Therapeutic decisions in patients with myelodysplastic syndromes (MDS) are very complex. The dilemma that confronts the management of MDS is illustrated by the presence of only one agent (5-azacitidine), which has been approved by the U.S.A. Food and Drug Administration, with an indication for all subtypes of this disease and another one (lenalidomide) for the management of a specific MDS subgroup, the 5q-syndrome. Current classifications and prognostic systems do not take into account the considerable clinical heterogeneity of MDS or their diverse biology. Supportive care, low-intensity treatment, acute myeloid leukemia-type therapy, and stem cell transplantation (SCT) produce unsatisfactory results because patients continue to be exposed to the inherent complications of worsening cytopenias and leukemic transformation. Recent years have witnessed an evolution in our understanding of pathophysiology pathways in MDS. At the same time, many novel and targeted therapies are being investigated in clinical trials, offering patients the prospect of sustained benefit and changing the natural course of the disease. Hypomethylating agents, immunomodulatory drugs, and farnesyl-tranferase inhibitors have produced very promising results in terms of response and survival in MDS patients. This review summarizes all recent data on the role of novel agents and SCT in the treatment of patients with MDS in an attempt to better understand their possible therapeutic status in the management of these patients.
