Novel agents in the treatment of Hodgkin lymphoma: Biological basis and clinical results.

ABSTRACT: Hodgkin Lymphoma (HL) is a lymphoproliferative disorder of B cells that commonly has a favorable prognosis when treated with either combination chemotherapy and radiation therapy, or chemotherapy alone. However, the prognosis for patients who relapse, or have evidence for refractory disease, is poor and new treatments are needed for patients with progressive disease. HL has a unique tumor microenvironment consisting of a predominance of inflammatory cells and a minority of malignant Hodgkin and Reed-Sternberg (HRS) cells. This unique biology provides an opportunity for novel therapy approaches that either specifically target the malignant HRS cell or target the inflammatory tumor microenvironment. New therapies including antibody drug conjugates targeting CD30, small molecule inhibitors that inhibit critical cell signaling pathways, monoclonal antibodies that block immune checkpoints, or agents that modulate the immune microenvironment have all recently been tested in HL with significant clinical activity. Multiple clinical trials are currently ongoing testing these agents in the relapsed and refractory setting but also in earlier phases of therapy often in combination with more standard treatment.

Incorporating novel agents into frontline treatment of Hodgkin lymphoma.

Project description:Classical Hodgkin lymphoma (cHL) is associated with excellent outcomes with standard frontline chemotherapy or combined modality therapy. However, up to 25% of patients will have relapsed or primary refractory (RR) cHL. Improving the cure rate with frontline treatment, treatment-related complications and late effects, and poor therapy tolerance with high relapse rates in older patients are unmet needs in the initial management of cHL. The introduction of novel therapies, including the CD30-directed antibody drug conjugate brentuximab vedotin and PD-1 blockade (ie, pembrolizumab or nivolumab), has transformed the treatment of RR cHL and has the potential to address these unmet needs in the frontline setting. Incorporation of these potent, targeted immunotherapies into frontline therapy may improve outcomes, may allow for de-escalation of therapy without sacrificing efficacy to reduce treatment complications, and may allow for well-tolerated and targeted escalation of therapy for patients demonstrating an insufficient response. In this article, we provide a case-based approach to the use of novel agents in the frontline treatment of cHL.

Novel Targeted Agents in Hodgkin and Non-Hodgkin Lymphoma Therapy.

Project description:There has been a recent emergence of novel targeted agents for treatment of Hodgkin and non-Hodgkin lymphoma. In particular, antibodies and antibody-drug conjugates directed against surface antigens, agents that block immune checkpoint pathways, and small molecule inhibitors directed against cell signaling pathways have shown significant promise in patients with relapsed and refractory disease and in the frontline setting. With the development of these new therapies, cytotoxic chemotherapy may be avoided entirely in some clinical settings. This review will present the latest information on these novel treatments in Hodgkin and non-Hodgkin lymphoma and will discuss both recently approved agents as well as drugs currently being studied in clinical trials.

Novel agents and immune invasion in Hodgkin lymphoma.

Project description:The approval of brentuximab vedotin (BV) and the PD-1 inhibitors nivolumab and pembrolizumab has dramatically improved outcomes for patients with relapsed or refractory (R/R) classic Hodgkin lymphoma (HL). With the goal of increasing long-term disease control rates and decreasing late toxicities, these agents are currently being tested in earlier phases of treatment in combination with chemotherapy agents. In the R/R setting, our expanding understanding of HL's various mechanisms of immune evasion and treatment resistance has spurred a growing number of rationally designed combination trials. Beyond BV and PD-1 blockade, other novel therapies have demonstrated encouraging preliminary results, including targeted agents, like the CD25 antibody-drug conjugate ADCT-301, and cellular therapies, including CD30 chimeric antigen receptor T cells and Epstein-Barr virus (EBV)-directed cytotoxic T cells. These trials, coupled with the rapid development of prognostic and predictive biomarkers, should drive additional breakthroughs that promise safer and more effective therapies for patients with HL in the future.

Novel Agents For Relapsed and Refractory Classical Hodgkin Lymphoma: A Review.

Project description:Classical Hodgkin lymphoma (cHL) is the most common type of HL that occurs mainly in people aged between 15-30 and over 55 years. Although its general prognosis is favorable, 10%-30% of patients with cHL will ultimately develop relapsed or refractory disease (r/r cHL). Improving the cure rate of r/r cHL has proven to be challenging. Some novel agents, such as brentuximab vedotin and immune checkpoint inhibitors, which have been used in conventional regimens for patients with r/r cHL in the past decade, have been shown to have good curative effects. This paper reviews the conventional regimens for patients with r/r cHL and focuses on the newest clinical trials and treatment measures to prolong prognosis and reduce adverse events. The evaluation of prognosis plays a vital role in analyzing the risk of relapse or disease progression; thus, finding new predictive strategies may help treat patients with r/r cHL more efficaciously.

Treatment of classical Hodgkin lymphoma in young adults aged 18-30 years with a modified paediatric Hodgkin lymphoma protocol. Results of a multicentre phase II clinical trial (CRUK/08/012).

Project description:This phase II trial was designed to determine the safety and efficacy of a modified paediatric risk-stratified protocol in young adults (18-30 years) with classical Hodgkin Lymphoma. The primary end-point was neurotoxicity rate. The incidence of grade 3 neurotoxicity was 11% (80% CI, 5-19%); a true rate of neuropathy of >15% cannot be excluded. Neuropathy and associated deterioration in quality of life was largely reversible. The overall response rate was 100% with 40% complete remission (CR) rate. Twelve months disease-free survival (DFS) was 91%. We demonstrate that a risk-stratified paediatric combined modality treatment approach can be delivered to young adults without significant irreversible neuropathy.

Clinical Results of Hypomethylating Agents in AML Treatment.

Project description:Epigenetic changes play an important role in the development of acute myeloid leukemia (AML). Unlike gene mutations, epigenetic changes are potentially reversible, which makes them attractive for therapeutic intervention. Agents that affect epigenetics are the DNA methyltransferase inhibitors, azacitidine and decitabine. Because of their relatively mild side effects, azacitidine and decitabine are particularly feasible for the treatment of older patients and patients with co-morbidities. Both drugs have remarkable activity against AML blasts with unfavorable cytogenetic characteristics. Recent phase 3 trials have shown the superiority of azacitidine and decitabine compared with conventional care for older AML patients (not eligible for intensive treatment). Results of treatment with modifications of the standard azacitidine (seven days 75 mg/m(2) SC; every four weeks) and decitabine (five days 20 mg/m(2) IV; every four weeks) schedules have been reported. Particularly, the results of the 10-day decitabine schedule are promising, revealing complete remission (CR) rates around 45% (CR + CRi (i.e., CR with incomplete blood count recovery) around 64%) almost comparable with intensive chemotherapy. Application of hypomethylating agents to control AML at the cost of minimal toxicity is a very promising strategy to "bridge" older patients with co-morbidities to the potential curative treatment of allogeneic hematopoietic cell transplantation. In this article, we discuss the role of DNA methyltransferase inhibitors in AML.

Hodgkin lymphoma.

Project description:Hodgkin lymphoma (HL), a B cell-derived cancer, is one of the most common lymphomas. In HL, the tumor cells--Hodgkin and Reed-Sternberg (HRS) cells--are usually very rare in the tissue. Although HRS cells are derived from mature B cells, they have largely lost their B cell phenotype and show a very unusual co-expression of markers of various hematopoietic cell types. HRS cells show deregulated activation of multiple signaling pathways and transcription factors. The activation of these pathways and factors is partly mediated through interactions of HRS cells with various other types of cells in the microenvironment, but also through genetic lesions. The transforming events involved in the pathogenesis of HL are only partly understood, but mutations affecting the NF-?B and JAK/STAT pathways are frequent. The dependency of HRS cells on microenvironmental interactions and deregulated signaling pathways may offer novel strategies for targeted therapies.

Introduction of novel agents in the treatment of primary CNS lymphoma.

Project description:Novel insights into the pathophysiology of primary central nervous system lymphoma (PCNSL) have identified the B-cell receptor and Toll-like receptor pathway as well as immune evasion and suppressed tumor immune microenvironment as a key mechanism in the pathogenesis of PCNSL. Small molecules and novel agents targeting these aberrant pathways have been introduced into clinical trials targeting the recurrent or refractory PCNSL patient population. Agents like the Bruton tyrosine kinase (BTK) inhibitor ibrutinib or immunomodulatory drugs (IMiDs) like pomalidomide and lenalidomide have shown promising high response rates in the salvage setting. Here, we give an overview about the recent, exciting developments in PCNSL and summarize the results of clinical trials using novel agents in the recurrent and refractory salvage setting, which include immune checkpoint inhibitors, IMiDs, as well as BTK, phosphatidylinositol-3 kinase, and mammalian target of rapamycin inhibitors.

Novel target and treatment agents for natural killer/T-cell lymphoma.

Project description:The rapidly increasing use of high-throughput screening had produced a plethora of expanding knowledge on the molecular basis of natural killer/T-cell lymphoma (NKTCL), which in turn has revolutionized the treatment. Specifically, the use of asparaginase-containing regimens has led to substantial improvement in survival outcomes in NKTCL patients. Novel treatment strategies that are currently under development include cell-surface-targeted antibodies, immune checkpoint inhibitors, Epstein-Barr virus targeted cytotoxic T lymphocyte, immunomodulatory agents, chimeric antigen receptor T cells, signaling pathway inhibitors and epigenetic targeted agents. In almost all cases, initial clinical studies of newly developed treatment are conducted in patients relapsed, and refractory NKTCL due to very limited treatment options. This review summarizes the results of these novel treatments for NKTCL and discusses their potential for likely use in NKTCL in a wider setting in the future.
