RESUMEN

Treatment of relapsed/refractory diffuse large B-cell lymphoma remains a challenge with the advent of chimaeric antigen receptor CAR-T cell treatment. Whether or not eligibility criteria should replace the standard autologous transplantation is debated. By using PET-derived parameters, the report of Cherng and colleagues suggests that patients with positive residual mass can have a five-year survival of 54% with standard treatment.

RESUMEN

First-line therapy for younger patients with peripheral T-cell non-Hodgkin lymphoma (T-NHL) consists of 6 courses of cyclophosphamide, doxorubicin, vincristine, and prednisone (CHOP) with or without etoposide (CHOEP), consolidated by high-dose therapy and autologous stem cell transplantation (auto-SCT). We hypothesized that allogeneic stem cell transplantation (allo-SCT) could improve outcomes. 104 patients with peripheral T-cell non-Hodgkin lymphoma, except ALK+ anaplastic large cell lymphoma, 18 to 60 years, all stages, and all age adjusted International Prognostic Index scores, except 0 and stage I, were randomized to 4 cycles of CHOEP and 1 cycle of dexamethasone, cytosine-arabinoside, and platinum (DHAP) followed by high-dose therapy and auto-SCT or myeloablative conditioning and allo-SCT. The primary end point was event-free survival (EFS) at 3 years. After a median follow-up of 42 months, the 3-year EFS after allo-SCT was 43%, as compared with 38% after auto-SCT. Overall survival at 3 years was 57% vs 70% after allo- or auto-SCT, without significant differences between treatment arms. None of the 21 responding patients proceeding to allo-SCT relapsed, as opposed to 13 of 36 patients (36%) proceeding to auto-SCT. Eight of 26 patients (31%) and none of 41 patients died of transplant-related toxicity after allo- and auto-SCT, respectively. The strong graft-versus-lymphoma effect after allo-SCT was counterbalanced by transplant-related mortality. This trial is registered at www.clinicaltrials.gov as #NCT00984412.

RESUMEN

Isatuximab is a monoclonal antibody that binds to the human CD38 antigen. On May 30, 2020, a marketing authorization valid through the European Union (EU) was issued for isatuximab in combination with pomalidomide and dexamethasone (IsaPd) for the treatment of adult patients with relapsed and refractory (RR) multiple myeloma (MM). The recommended dose of isatuximab was 10 mg/kg, administered intravenously weekly at cycle 1 and then biweekly in subsequent 28-day cycles. Isatuximab was evaluated in a phase III, open-label, multicenter, randomized trial that randomly allocated IsaPd versus pomalidomide plus dexamethasone (Pd) to adult patients with RR MM. The primary endpoint of the trial was progression-free survival, as assessed by an independent review committee, which was superior for the IsaPd arm (hazard ratio, 0.596; 95% confidence interval, 0.436-0.814; p = .001) compared with the Pd arm. Treatment with IsaPd led to higher incidences of treatment-related adverse events (AEs), grade ≥ 3 AEs, and serious AEs compared with Pd treatment. Most frequently observed AEs that occurred more often in the IsaPd arm were infusion-related reactions, infections, respiratory AEs, neutropenia (including neutropenic complications), and thrombocytopenia. The aim of this article is to summarize the scientific review of the application leading to regulatory approval in the EU. IMPLICATIONS FOR PRACTICE: Isatuximab was approved in the European Union, in combination with pomalidomide and dexamethasone, for the treatment of patients with multiple myeloma who have already received therapy but whose disease did not respond or relapsed afterward. The addition of isatuximab resulted in a clinically meaningful and significant prolongation of the time from treatment initiation to further disease relapse or patient's death. The safety profile was considered acceptable, and the benefit-risk ratio was determined to be positive.

RESUMEN

On November 5, 2020, a marketing authorization valid through the European Union (EU) was issued for acalabrutinib monotherapy or acalabrutinib in combination with obinutuzumab (AcalaObi) in adult patients with treatment-naïve (TN) chronic lymphocytic leukemia (CLL) and also for acalabrutinib monotherapy in adult patients with relapsed or refractory (RR) CLL. Acalabrutinib inhibits the Bruton tyrosine kinase, which plays a significant role in the proliferation and survival of the disease. Acalabrutinib was evaluated in two phase III multicenter randomized trials. The first trial (ACE-CL-007) randomly allocated acalabrutinib versus AcalaObi versus chlorambucil plus obinutuzumab (ChlObi) to elderly/unfit patients with TN CLL. The progression-free survival (PFS), as assessed by an independent review committee, was superior for both the AcalaObi (hazard ratio [HR], 0.1; 95% confidence interval [CI], 0.06-0.17) and acalabrutinib (HR, 0.2; 95% CI, 0.13-0.3) arms compared with the ChlObi arm. The second trial (ACE-CL-309) randomly allocated acalabrutinib versus rituximab plus idelalisib or bendamustine to adult patients with RR CLL. Also in this trial, the PFS was significantly longer in the acalabrutinib arm (HR, 0.31; 95% CI, 0.20-0.49). Adverse events for patients receiving acalabrutinib varied across trials, but the most frequent were generally headache, diarrhea, neutropenia, nausea, and infections. The scientific review concluded that the benefit-risk ratio of acalabrutinib was positive for both indications. This article summarizes the scientific review of the application leading to regulatory approval in the EU. IMPLICATIONS FOR PRACTICE: Acalabrutinib was approved in the European Union for the treatment of adult patients with chronic lymphocytic leukemia who have not received treatment before and for those who have received therapy but whose disease did not respond or relapsed afterward. Acalabrutinib resulted in a clinically meaningful and significant lengthening of the time from treatment initiation to further disease relapse or patient's death compared with standard therapy. The overall safety profile was considered acceptable, and the benefit-risk ratio was determined to be positive.

RESUMEN

On August 25, 2020, a marketing authorization valid through the European Union was issued for belantamab mafodotin monotherapy for the treatment of multiple myeloma (MM) in adult patients who have received at least four prior therapies, whose disease is refractory to at least one proteasome inhibitor (PI), one immunomodulatory agent (IMiD), and an anti-CD38 monoclonal antibody (mAb), and who have demonstrated disease progression on the last therapy. Belantamab mafodotin is an antibody-drug conjugate that combines a mAb, which binds specifically to B-cell maturation antigen, with maleimidocaproyl monomethyl auristatin F, which is a cytotoxic agent. It was evaluated in Study 205678 (DREAMM-2), an open-label, two arm, phase II, multicenter study in patients with MM who had relapsed following treatment with at least three prior therapies, who were refractory to an IMiD, a PI, and an anti-CD38 mAb alone or in combination. Patients were randomized to receive 2.5 mg/kg (n = 97) or 3.4 mg/kg (n = 99) belantamab mafodotin by intravenous infusion every 3 weeks until disease progression or unacceptable toxicity. Belantamab mafodotin achieved an overall response rate (ORR) of 32% (97.5% confidence interval [CI]: 22-44) with a median duration of response (DoR) of 11 months (95% CI: 4.2 to not reached). The most frequently (≥20%) reported adverse reactions grades 3-4 with belantamab mafodotin were keratopathy (31%), thrombocytopenia (22%), and anemia (21%). With regard to the corneal risks associated with belantamab mafodotin, patients would need to undergo specific ophthalmic examinations so that any findings can be promptly and adequately managed. The scientific review concluded that a 32% ORR and a median DoR of 11 months observed with belantamab mafodotin was considered clinically meaningful. Given the manageable toxicity profile and considering that belantamab mafodotin has a mechanism of action that is different from that of authorized treatments in this group of highly pretreated patients whose disease is refractory to three classes of agents, the benefit risk for belantamab mafodotin monotherapy was considered positive, although the efficacy and safety evidence were not as comprehensive as normally required. IMPLICATIONS FOR PRACTICE: Belantamab mafodotin (Blenrep, GlaxoSmithKline, St. Louis, MO, U.S.A) was approved in the European Union as monotherapy for the treatment of adult patients with refractory/relapsed multiple myeloma. Belantamab mafodotin resulted in durable response in highly pretreated patients whose disease is refractory to three classes of agents. Belantamab mafodotin is a monoclonal antibody against B-cell maturation antigen conjugated with the potent antimitotic agent maleimidocaproyl monomethyl auristatin. This is the first monoclonal antibody to target this antigen in multiple myeloma, which represents a true novelty from a pharmacological point of view.

RESUMEN

On November 15, 2018, the Committee for Medicinal Products for Human Use (CHMP) recommended the extension of indication for blinatumomab to include the treatment of adults with minimal residual disease (MRD) positive B-cell precursor acute lymphoblastic leukemia (ALL). Blinatumomab was authorized to treat relapsed or refractory B-precursor ALL, and the change concerned an extension of use. On March 29, 2018, the U.S. Food and Drug Administration (FDA) granted accelerated approval to blinatumomab to treat both adults and children with B-cell precursor ALL who are in remission but still have MRD. On July 26, 2018, the CHMP had originally adopted a negative opinion on the extension. The reason for the initial refusal was that although blinatumomab helped to reduce the amount of residual cancer cells in many patients, there was no strong evidence that it led to improved survival. During the re-examination, the CHMP consulted the scientific advisory group. The CHMP agreed with the expert group's conclusion that, although there was no strong evidence of patients living longer, the available data from the main study (MT103-203) indicated a good durable response to blinatumomab, with an overall complete response rate for the primary endpoint full analysis set (defined as all subjects with an Ig or T-cell receptor polymerase chain reaction MRD assay with the minimum required sensitivity of 1 × 10-4 at central lab established at baseline [n = 113]) as 79.6% (90/113; 95% confidence interval, 71.0-86.6), with a median time to complete MRD response of 29.0 days (range, 5-71). Therefore, the CHMP concluded that the benefits of blinatumomab outweigh its risks and recommended granting the change to the marketing authorization. The Committee for Orphan Medicinal Products, following reassessment, considered that significant benefit continued to be met and recommended maintaining the orphan designation and thus 10 years market exclusivity (the Orphan Designation is a legal procedure that allows for the designation of a medicinal substance with therapeutic potential for a rare disease, before its first administration in humans or during its clinical development). The marketing authorization holder for this medicinal product is Amgen Europe B.V. IMPLICATIONS FOR PRACTICE: Immunotherapy with blinatumomab has excellent and sustainable results, offering new hope for patients with minimal residual disease-positive acute lymphoblastic leukemia, a disease with poor prognosis. New recommendations and change of practice for treatment of this patient group are detailed.

RESUMEN

On June 28, 2018, the Committee for Advanced Therapies and the Committee for Medicinal Products for Human Use adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Yescarta for the treatment of adult patients with relapsed or refractory diffuse large B-cell lymphoma and primary mediastinal large B-cell lymphoma, after two or more lines of systemic therapy. Yescarta, which was designated as an orphan medicinal product and included in the European Medicines Agency's Priority Medicines scheme, was granted an accelerated review timetable. The active substance of Yescarta is axicabtagene ciloleucel, an engineered autologous T-cell immunotherapy product whereby a patient's own T cells are harvested and genetically modified ex vivo by retroviral transduction using a retroviral vector to express a chimeric antigen receptor (CAR) comprising an anti-CD19 single chain variable fragment linked to CD28 costimulatory domain and CD3-zeta signaling domain. The transduced anti-CD19 CAR T cells are expanded ex vivo and infused back into the patient, where they can recognize and eliminate CD19-expressing cells. The benefits of Yescarta as studied in ZUMA-1 phase II (NCT02348216) were an overall response rate per central review of 66% (95% confidence interval, 56%-75%) at a median follow-up of 15.1 months in the intention to treat population and a complete response rate of 47% with a significant duration. The most common adverse events were cytokine release syndrome, neurological adverse events, infections, pyrexia, diarrhea, nausea, hypotension, and fatigue. IMPLICATIONS FOR PRACTICE: Yescarta (axicabtagene ciloleucel) was the first chimeric antigen receptor T-cell therapy to be submitted for evaluation to the European Medicines Agency and admitted into the "priority medicine" scheme; it was granted accelerated assessment on the basis of anticipated clinical benefit in relapsed/refractory diffuse large B-cell lymphoma, a condition of unmet medical need. Indeed, Yescarta showed an overall response rate of 66% and a complete response rate of 47% with a significant duration and a manageable toxicity that compared very favorably with historical controls. Here the analysis of benefits and risks is presented, and specific challenges with this important novel product are highlighted, providing further insights and reflections for future medical research.

RESUMEN

On October 24, 2019, a marketing authorization valid through the European Union (EU) was issued for gilteritinib monotherapy for adult patients who have relapsed or refractory acute myeloid leukemia (AML) with an Fms-like tyrosine kinase 3 (FLT3) mutation. Gilteritinib inhibits FLT3 receptor signaling and proliferation in cells exogenously expressing FLT3 including FLT3 internal tandem duplication (ITD), FLT3 D835Y, and FLT3 ITD D835Y, and it induced apoptosis in leukemic cells expressing FLT3 ITD. The recommended starting dose of gilteritinib is 120 mg (three 40 mg tablets) once daily. Gilteritinib was evaluated in one, phase III, open-label, multicenter, randomized study of gilteritinib (n = 247, gilteritinib arm) versus salvage chemotherapy (n = 124, salvage chemotherapy arm) in patients with relapsed or refractory AML with FLT3 mutation. Overall survival (OS) was statistically significantly different between the two groups with a median OS of 9.3 months in the gilteritinib arm compared with 5.6 months for salvage chemotherapy (hazard ratio, 0.637; 95% confidence interval, 0.490-0.830; p = .0004 one-sided log-rank test). The most common adverse reactions with gilteritinib treatment were blood creatine phosphokinase increase, alanine aminotransferase increase, aspartate aminotransferase increase, blood alkaline phosphatase increase, diarrhea, fatigue, nausea, constipation, cough, peripheral edema, dyspnea, dizziness, hypotension, pain in extremity, asthenia, arthralgia, and myalgia. The objective of this article is to summarize the scientific review of the application leading to regulatory approval in the EU. IMPLICATIONS FOR PRACTICE: Xospata was approved in the European Union as monotherapy for the treatment of adult patients with relapsed or refractory acute myeloid leukemia (AML) with an Fms-like tyrosine kinase 3 (FLT3) mutation. Gilteritinib resulted in a clinically meaningful and statistically significant improvement of overall survival compared with salvage chemotherapy. At the time of the marketing authorization of gilteritinib, there were no approved standard therapies specifically for adult patients diagnosed with relapsed or refractory AML with FLT3 mutation. In terms of safety, the overall accepted safety profile was considered manageable.

RESUMEN

Chimeric antigen receptor (CAR)-engineered T-cell therapy is becoming one of the most promising approaches in the treatment of cancer. On June 28, 2018, the Committee for Advanced Therapies (CAT) and the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Kymriah for pediatric and young adult patients up to 25 years of age with B-cell acute lymphoblastic leukemia (ALL) that is refractory, in relapse after transplant, or in second or later relapse and for adult patients with relapsed or refractory diffuse large B-cell lymphoma (DLBCL) after two or more lines of systemic therapy. Kymriah became one of the first European Union-approved CAR T therapies. The active substance of Kymriah is tisagenlecleucel, an autologous, immunocellular cancer therapy that involves reprogramming the patient's own T cells to identify and eliminate CD19-expressing cells. This is achieved by addition of a transgene encoding a CAR. The benefit of Kymriah was its ability to achieve remission with a significant duration in patients with ALL and an objective response with a significant duration in patients with DLBCL. The most common hematological toxicity was cytopenia in both patients with ALL and those with DLBCL. Nonhematological side effects in patients with ALL were cytokine release syndrome (CRS), infections, secondary hypogammaglobulinemia due to B-cell aplasia, pyrexia, and decreased appetite. The most common nonhematological side effects in patients with DLBCL were CRS, infections, pyrexia, diarrhea, nausea, hypotension, and fatigue. Kymriah also received an orphan designation on April 29, 2014, following a positive recommendation by the Committee for Orphan Medicinal Products (COMP). Maintenance of the orphan designation was recommended at the time of marketing authorization as the COMP considered the product was of significant benefit for patients with both conditions. IMPLICATIONS FOR PRACTICE: Chimeric antigen receptor (CAR)-engineered T-cell therapy is becoming the most promising approach in cancer treatment, involving reprogramming the patient's own T cells with a CAR-encoding transgene to identify and eliminate cancer-specific surface antigen-expressing cells. On June 28, 2018, Kymriah became one of the first EMA approved CAR T therapies. CAR T technology seems highly promising for diseases with single genetic/protein alterations; however, for more complex diseases there will be challenges to target clonal variability within the tumor type or clonal evolution during disease progression. Products with a lesser toxicity profile or more risk-minimization tools are also anticipated.

RESUMEN

Autologous stem cell transplantation (ASCT) is a well-established approach to treatment of patients with relapsed/refractory (R/R) Hodgkin lymphoma (HL) recommended by both the European Society for Medical Oncology and the National Comprehensive Cancer Network based on the results from randomized controlled studies. However, a considerable number of patients who receive ASCT will progress/relapse and display suboptimal post-transplant outcomes. Over recent years, a number of different strategies have been assessed to improve post-ASCT outcomes and augment HL cure rates. These include use of pre- and post-ASCT salvage therapies and post-ASCT consolidative therapy, with the greatest benefits demonstrated by targeted therapies, such as brentuximab vedotin. However, adoption of these new approaches has been inconsistent across different centers and regions. In this article, we provide a European perspective on the available treatment options and likely future developments in the salvage and consolidation settings, with the aim to improve management of patients with HL who have a high risk of post-ASCT failure. CONCLUSIONS: We conclude that early intervention with post-ASCT consolidation improves outcomes in patients with R/R HL who require ASCT. Future approvals of targeted agents are expected to further improve outcomes and provide additional treatment options in the coming age of personalized medicine.

RESUMEN

BACKGROUND: Outcomes for patients with peripheral T-cell lymphoma (PTCL) who fail to achieve complete response (CR) or relapse after front-line therapy are poor with lack of prospective outcomes data. OBJECTIVES: COMPLETE is a prospective registry of 499 patients enrolled at academic and community sites in the United States detailing patient demographics, treatment and outcomes for patients with aggressive T cell lymphomas. We report results for patients with primary refractory and relapsed disease. METHODS: Primary refractory disease was defined as an evaluable best response to initial treatment (induction ± maintenance or consolidation/transplant) other than CR, and included a partial response, progressive disease, or no response/stable disease. Relapsed disease was defined as an evaluable best response to initial treatment of CR, followed by disease progression at a later date, irrespective of time to progression. Patients were included in the analysis if initial treatment began within 30 days of enrollment and treatment duration was ≥4 days. RESULTS: Of 420 evaluable patients, 97 met the definition for primary refractory and 58 with relapsed disease. In the second-line setting, relapsed patients received single-agent therapies more often than refractory patients (52 vs. 28%; p = 0.01) and were more likely to receive single-agent regimens (74 vs. 53%; p = 0.03). The objective response rate to second-line therapy was higher in relapsed patients (61 vs. 40%; p = 0.04) as was the proportion achieving a CR (41 vs. 14%; p = 0.002). Further, relapsed patients had longer overall survival (OS) compared to refractory patients, with a median OS of 29.1 versus 12.3 months. CONCLUSIONS: Despite the availability of newer active single agents, refractory patients were less likely to receive these therapies and continue to have inferior outcomes compared to those with relapsed disease. PTCL in the real world remains an unmet medical need, and improvements in front-line therapies are needed.

RESUMEN

BACKGROUND: The role of autologous stem cell transplantation (ASCT) in the first complete remission (CR1) of peripheral T-cell lymphomas (PTCLs) is not well defined. This study analyzed the impact of ASCT on the clinical outcomes of patients with newly diagnosed PTCL in CR1. METHODS: Patients with newly diagnosed, histologically confirmed, aggressive PTCL were prospectively enrolled into the Comprehensive Oncology Measures for Peripheral T-Cell Lymphoma Treatment (COMPLETE) study, and those in CR1 were included in this analysis. RESULTS: Two hundred thirteen patients with PTCL achieved CR1, and 119 patients with nodal PTCL, defined as anaplastic lymphoma kinase-negative anaplastic large cell lymphoma, angioimmunoblastic T-cell lymphoma (AITL), or PTCL not otherwise specified, were identified. Eighty-three patients did not undergo ASCT, whereas 36 underwent consolidative ASCT in CR1. At the median follow-up of 2.8 years, the median overall survival was not reached for the entire cohort of patients who underwent ASCT, whereas it was 57.6 months for those not receiving ASCT (P = .06). ASCT was associated with superior survival for patients with advanced-stage disease or intermediate-to-high International Prognostic Index scores. ASCT significantly improved overall and progression-free survival for patients with AITL but not for patients with other PTCL subtypes. In a multivariable analysis, ASCT was independently associated with improved survival (hazard ratio, 0.37; 95% confidence interval, 0.15-0.89). CONCLUSIONS: This is the first large prospective cohort study directly comparing the survival outcomes of patients with nodal PTCL in CR1 with or without consolidative ASCT. ASCT may provide a benefit in specific clinical scenarios, but the broader applicability of this strategy should be determined in prospective, randomized trials. These results provide a platform for designing future studies of previously untreated PTCL.

RESUMEN

On February 22, 2018, the Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product gemtuzumab ozogamicin (Mylotarg; Pfizer, New York City, NY), intended for the treatment of acute myeloid leukemia. Mylotarg was designated as an orphan medicinal product on October 18, 2000. The applicant for this medicinal product was Pfizer Limited (marketing authorization now held by Pfizer Europe MA EEIG).The demonstrated benefit with Mylotarg is improvement in event-free survival. This has been shown in the pivotal ALFA-0701 (MF-3) study. In addition, an individual patient data meta-analysis from five randomized controlled trials (3,325 patients) showed that the addition of Mylotarg significantly reduced the risk of relapse (odds ratio [OR] 0.81; 95% CI: 0.73-0.90; p = .0001), and improved overall survival at 5 years (OR 0.90; 95% CI: 0.82-0.98; p = .01) [Lancet Oncol 2014;15:986-996]. The most common (>30%) side effects of Mylotarg when used together with daunorubicin and cytarabine are hemorrhage and infection.The full indication is as follows: "Mylotarg is indicated for combination therapy with daunorubicin (DNR) and cytarabine (AraC) for the treatment of patients age 15 years and above with previously untreated, de novo CD33-positive acute myeloid leukemia (AML), except acute promyelocytic leukemia (APL)."The objective of this article is to summarize the scientific review done by the CHMP of the application leading to regulatory approval in the European Union. The full scientific assessment report and product information, including the Summary of Product Characteristics, are available on the European Medicines Agency website (www.ema.europa.eu). IMPLICATIONS FOR PRACTICE: This article reflects the scientific assessment of Mylotarg (gemtuzumab ozogamicin; Pfizer, New York City, NY) use for the treatment of acute myeloid leukemia based on important contributions from the rapporteur and co-rapporteur assessment teams, Committee for Medicinal Products for Human Use members, and additional experts following the application for a marketing authorization from the company. It's a unique opportunity to look at the data from a regulatory point of view and the importance of assessing the benefit-risk.

RESUMEN

Diffuse large B-cell lymphoma (DLBCL) is the most common subtype of non-Hodgkin lymphoma. Although 5-year survival rates in the first-line setting range from 60% to 70%, up to 50% of patients become refractory to or relapse after treatment. Published analyses of large-scale outcome data from patients with refractory DLBCL are limited. SCHOLAR-1, an international, multicohort retrospective non-Hodgkin lymphoma research study, retrospectively evaluated outcomes in patients with refractory DLBCL which, for this study, was defined as progressive disease or stable disease as best response at any point during chemotherapy (>4 cycles of first-line or 2 cycles of later-line therapy) or relapsed at ≤12 months from autologous stem cell transplantation. SCHOLAR-1 pooled data from 2 phase 3 clinical trials (Lymphoma Academic Research Organization-CORAL and Canadian Cancer Trials Group LY.12) and 2 observational cohorts (MD Anderson Cancer Center and University of Iowa/Mayo Clinic Lymphoma Specialized Program of Research Excellence). Response rates and overall survival were estimated from the time of initiation of salvage therapy for refractory disease. Among 861 patients, 636 were included on the basis of refractory disease inclusion criteria. For patients with refractory DLBCL, the objective response rate was 26% (complete response rate, 7%) to the next line of therapy, and the median overall survival was 6.3 months. Twenty percent of patients were alive at 2 years. Outcomes were consistently poor across patient subgroups and study cohorts. SCHOLAR-1 is the largest patient-level pooled retrospective analysis to characterize response rates and survival for a population of patients with refractory DLBCL.

RESUMEN

Single agents have demonstrated activity in relapsed and refractory (R/R) peripheral T-cell lymphoma (PTCL). Their benefit relative to combination chemotherapy remains undefined. Patients with histologically confirmed PTCL were enrolled in the Comprehensive Oncology Measures for Peripheral T-cell Lymphoma Treatment (COMPLETE) registry. Eligibility criteria included those with R/R disease who had received one prior systemic therapy and were given either a single agent or combination chemotherapy as first retreatment. Treatment results for those with R/R disease who received single agents were compared to those who received combination chemotherapy. The primary endpoint was best response to retreatment. Fifty-seven patients met eligibility criteria. At first retreatment, 46% (26/57) received combination therapy and 54.5% (31/57) received single agents. At median follow up of 2 years, a trend was seen towards increased complete response rate for single agents versus combination therapy (41% vs 19%; P = .02). There was also increased median overall survival (38.9 vs 17.1 months; P = .02) and progression-free survival (11.2 vs 6.7 months; P = .02). More patients receiving single agents received hematopoietic stem-cell transplantation (25.8% vs 7.7%, P = .07). Adverse events of grade 3 or 4 occurred more frequently in those receiving combination therapy, although this was not statistically significant. The data confirm the unmet need for better treatment in R/R PTCL. Despite a small sample, the analysis shows greater response and survival in those treated with single agents as first retreatment in R/R setting, while maintaining the ability to achieve transplantation. Large, randomized trials are needed to identify the best strategy.

RESUMEN

Despite progress in the upfront treatment of diffuse large B cell lymphoma (DLBCL), patients still experience relapses. Salvage chemotherapy followed by autologous stem cell transplantation (ASCT) is the standard second-line treatment for relapsed and refractory (R/R) DLBCL. However, half of the patients will not be eligible for transplantation due to ineffective salvage treatment, and the other half will relapse after ASCT. In randomized studies, no salvage chemotherapy regimen is superior to another. The outcomes are affected by the secondary International Prognostic Index at relapse and various biological factors. The strategy is less clear in patients who require third-line treatment. A multicohort retrospective non-Hodgkin lymphoma research (SCHOLAR-1) study conducted in 636 patients with refractory DLBCL showed an objective response rate of 26% (complete response 7%) to the next line of therapy with a median overall survival of 6·3 months. In the case of a response followed by transplantation, long-term survival can be achieved in DLBCL patients. There is clearly a need for new drugs that improve salvage efficacy. Encouraging results have been reported with chimeric antigen receptor -T cell engineering, warranting further studies in a well-defined control group of refractory patients. The Collaborative Trial in Relapsed Aggressive Lymphoma (CORAL) was used as a handy framework to build the discussion.

RESUMEN

On August 28, 2015, a marketing authorization valid through the European Union was issued for panobinostat, in combination with bortezomib and dexamethasone, for the treatment of adult patients with relapsed and/or refractory multiple myeloma who have received at least two prior regimens including bortezomib and an immunomodulatory agent (IMiD).Panobinostat is an orally available histone deacetylase (HDAC) inhibitor that inhibits the enzymatic activity of HDAC proteins at nanomolar concentrations. HDAC proteins catalyze the removal of acetyl groups from the lysine residues of histones and some nonhistone proteins. Inhibition of HDAC activity results in increased acetylation of histone proteins, an epigenetic alteration that results in a relaxing of chromatin, leading to transcriptional activation. The recommended starting dose of panobinostat is 20 mg, taken orally in a cyclical manner for up to 48 weeks.The use of panobinostat in combination with bortezomib and dexamethasone was studied in a randomized, double-blind, placebo-controlled, multicenter phase III study (PANORAMA I) in 768 patients with relapsed or relapsed and refractory multiple myeloma who had received one to three prior lines of therapies. In the subgroup of patients who have received at least two prior regimens including bortezomib and an IMiD, there was a difference of 7.8 months in the progression-free survival in favor of the experimental arm (12.5 months for panobinostat + bortezomib + dexamethasone vs. 4.7 months for placebo + bortezomib + dexamethasone; hazard ratio = 0.47, 95% confidence interal 0.31-0.72; log-rank p value = .0003). The incidence of grade 3-4 adverse events suspected to be related to study drug was 76.9% vs. 51.2%, for the panobinostat and the placebo group, respectively. The most common side effects (grade 3-4) associated with panobinostat included diarrhea (18.9%), fatigue (14.7%), nausea (4.5%), vomiting (5.5%), thrombocytopenia (43.6%), anemia (7.9%), neutropenia (16.5%) and lymphopenia (8.1%).This article summarizes the scientific review of the application leading to regulatory approval in the European Union. The full scientific assessment report and product information, including the Summary of Product Characteristics, are available on the European Medicines Agency website (http://www.ema.europa.eu/ema/index.jsp?curl=pages/includes/medicines/medicines_landing_page.jsp&mid=). IMPLICATIONS FOR PRACTICE: Farydak was approved in the European Union in combination with bortezomib and dexamethasone, for the treatment of adult patients with relapsed and/or refractory multiple myeloma who have received at least two prior regimens including bortezomib and an immunomodulatory agent (IMiD). The addition of panobinostat to bortezomib and dexamethasone resulted in a clinically meaningful and statistically significant improvement of progression-free survival compared with bortezomib and dexamethasone, and an additional therapeutic option with a new mechanism of action was considered valuable. Although the toxicity associated with panobinostat combination was significant, at the time of the marketing authorization of panobinostat, it was considered that it was acceptable and that it should be left to the clinician and the patient to decide whether the panobinostat combination is the preferred treatment option or not.

RESUMEN

On May 20, 2016, a conditional marketing authorization valid through the European Union (EU) was issued for daratumumab as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma, whose prior therapy included a proteasome inhibitor (PI) and an immunomodulatory drug (IMiD) and who had demonstrated disease progression on the last therapy. The review of daratumumab was conducted under the EMA's accelerated assessment program for drugs that are of major interest for public health, especially from the point of view of therapeutic innovation.Daratumumab monotherapy achieved an overall response rate of 29.2% (95% confidence interval [CI] 20.8 to 38.9) in patients with multiple myeloma who had received at least three prior lines of therapy (including a PI and IMiD) or were double refractory to a PI and an IMiD (Study MMY2002). In patients with multiple myeloma relapsed from or refractory to two or more different prior therapies, including IMiDs (e.g., thalidomide, lenalidomide) and PI, an overall response was observed in 15 patients (35.7%, 95% CI: 21.6 to 52.0) (Study GEN501).On April 28, 2017, the therapeutic indication was extended to include the use of daratumumab in combination with lenalidomide and dexamethasone, or bortezomib and dexamethasone, for the treatment of adult patients with multiple myeloma who have received at least one prior therapy. This was based on two subsequent phase III studies of daratumumab in combination with lenalidomide/low-dose dexamethasone (MMY3003) and bortezomib/low dose dexamethasone (MMY3004).The most common side effects (grade 3-4) associated with daratumumab included neutropenia (37%), thrombocytopenia (23%), anemia (16%), pneumonia (10%), lymphopenia (8%), infusion-related reactions (6%), upper respiratory tract infection (5%), and fatigue (5%).The objective of this study was to summarize the scientific review done by the CHMP of the application leading to regulatory approval in the EU. The full scientific assessment report and product information, including the Summary of Product Characteristics (SmPC), are available on the EMA website (www.ema.europa.eu). IMPLICATIONS FOR PRACTICE: A conditional Marketing authorization was issued in the European Union for daratumamb as monotherapy for the treatment of adult patients with relapsed and refractory multiple myeloma, based on the response rate data from two single-agent studies. Darzalex, a novel monoclonal antibody targeted against CD38, demonstrated a durable response rate in a heavily pre-treated population with limited treatment options based on the response rate data from two single-agent studies. The addition of daratumumab to lenalidomide and dexamethasone (study MMY3003), or bortezomib and dexamethasone (MMY3004), demonstrated a positive effect on progression-free survival in patients with multiple myeloma who had received at least one prior therapy. Following submission of the controlled data of the MMY3003 and MMY3004 studies, the efficacy and safety of daratumumab was confirmed and the approval of daratumumab was converted to standard approval.

RESUMEN

PURPOSE OF REVIEW: Peripheral T-cell lymphoma (PTCL) is a heterogeneous group of mature T-cell and natural killer (NK)-cell neoplasms in the WHO 2016 classification. Patient prognosis is poor when treated with CHOP, and there is an unmet need for new drugs. Several agents have been developed for PTCL, and their use is the subject of this review. RECENT FINDINGS: Phase 2 studies demonstrated the activity of new drugs in Relapsed/refractory PTCL. Only four compounds were approved by the food and drug administration: romidepsin and belinostat, which are epigenetic modifiers, the antifolate agent pralatrexate, the immuno-conjugate brentuximab vedotin. New combinations have been tested, but the results were disappointing. Given the latest progress in biology, targeted agents are evaluated in different subtypes of PTCL. Relapsed anaplastic large-cell lymphoma exhibits improved prognosis with the approved anti-CD30 drug conjugate brentuximab vedotin. Localized nasal NK/T is treated with radiotherapy and nonanthracycline chemotherapy with L-asparaginase. Recently, immune checkpoint inhibitors demonstrated activity in NK/T lymphoma and can be used in elderly patients. SUMMARY: Treatment remains a challenge for PTCL, and several targeted drugs provide new approaches. Progress will be made incrementally in the different subtypes. One of the critical situations facing new drugs is the ability to run robust clinical trials in rare diseases.

RESUMEN

Recognizing the significant biological and clinical heterogeneity of mature T cell and natural killer (NK)/T cell lymphomas, the American Society for Blood and Marrow Transplantation invited experts to develop clinical practice recommendations related to the role of autologous hematopoietic cell transplantation (auto-HCT) and allogeneic HCT (allo-HCT) for specific histological subtypes. We used the GRADE methodology to aid in moving from evidence to decision making and ultimately to generating final recommendations. Auto-HCT in front-line consolidation is recommended in peripheral T cell lymphoma not otherwise specified (PTCL-NOS), angioimmunoblastic T cell lymphoma (AITL), anaplastic large cell lymphoma-anaplastic lymphoma kinase (ALCL-ALK)-negative, NK/T cell (disseminated), enteropathy-associated T cell lymphoma (EATL), and hepatosplenic lymphomas. Auto-HCT in relapsed-sensitive disease is recommended for NK/T cell (localized and disseminated), EATL, subcutaneous panniculitis-like T cell, and ALCL-ALK-positive lymphomas. Auto-HCT is also recommended for PTCL-NOS, AITL, and ALCL-ALK-negative lymphomas if not performed as front-line therapy. Auto-HCT in refractory (primary or relapsed) disease is not recommended for any of the histological subtypes discussed. Allo-HCT in front-line consolidation is recommended for NK/T cell (disseminated), adult T cell leukemia/lymphoma (ATLL; acute and lymphoma type), and hepatosplenic lymphomas. Allo-HCT for relapsed-sensitive disease is recommended for PTCL-NOS, AITL, ALCL-ALK-negative, ALCL-ALK-positive, NK/T cell (localized and disseminated), ATLL (acute, lymphoma type, smoldering/chronic), mycosis fungoides/Sezary syndrome (advanced stage IIB-IVB or tumor stage/extracutaneous), EATL, subcutaneous panniculitis-like T cell, and hepatosplenic lymphoma. Allo-HCT in refractory (primary or relapsed refractory) disease is recommended for any aforementioned histological subtypes. Emerging novel therapies will likely be incorporated into the pretransplantation, peritransplantation, and post-transplantation algorithms (auto-HCT or allo-HCT) with the goals of optimizing efficacy and improving outcomes. We acknowledge that there are unique clinical scenarios not covered by these recommendations that may require individualized decisions.
