Intensive salvage chemotherapy with VDTPACE or mCBAD followed by hematopoietic stem-cell support for refractory/relapsed multiple myeloma.

INTRODUCTION: Triple- and quad-refractory multiple myeloma patients usually have an aggressive course and a poor prognosis. Available therapeutic options are scarce. METHODS: The objective of the current study was to evaluate responses and toxicities of VDTPACE or mCBAD with hematopoietic stem-cell support as a bridge to subsequent therapies in patients with refractory/relapsed multiple myeloma. RESULTS: Thirteen patients were included (11 mCBAD, 2 VDTPACE), and 21 cycles of chemotherapy with hematopoietic stem-cell support were delivered. Mean number of previous therapies was 4.8. Stem cells were infused on a median day 9.9 after chemotherapy. Mean time to neutrophil recovery was 18.2 days in patients receiving the first cycle and 15.9 following subsequent cycles. Before therapy, most patients were in PD (77%), PR (15%), or VGPR (8%). Following treatment, the best responses achieved were PR (46%), VGPR (46%), and CR (8%). Median overall and progression-free survivals were 17 and 9 months. There has been no case of non-relapse mortality. In the 21 cycles, the main complications were infectious. CONCLUSION: Intensive chemotherapy can decrease disease burden in patients with relapsed/refractory MM, and stem-cell support can successfully decrease toxicities and treatment-related mortality associated with these regimens and may be a good bridging option.

All about blinatumomab: the bispecific T cell engager immunotherapy for B cell acute lymphoblastic leukemia

ABSTRACT Introduction: B cell acute lymphoblastic leukemia-lymphoma (B-ALL) accounts for approximately 75% of ALL cases and is observed in children and adults. Recent advances in disease diagnosis, stratification and prognostication have led to a better characterization of different subgroups of ALL. Notwithstanding the significant improvement in the complete remission rate of B-ALL, patients with minimal residual disease (MRD) and relapsed/refractory (R/R) settings suffer from poor outcomes. Hypothesis: However, novel therapies, such as agents targeting tyrosine kinases or the CD20 molecule, combination therapies and improved supportive care, have changed the treatment landscape of B-ALL. Method and results: Meanwhile, blinatumomab has been FDA-approved for MRD-positive or R/R B-ALL patients. Blinatumomab is a bispecific T cell engager containing the CD3 and CD19 that recognize domains redirecting cytotoxic T cells to lyse B cells. Promising outcomes, including long-term overall survival and improved MRD-negative response rates, have been reported in patients who received this drug. Adding blinatumomab to new ALL regimens seems promising for achieving better outcomes in poor prognosis B-ALL patients. Nevertheless, the neurotoxicity and cytokine release syndrome are the two major adverse events following the blinatumomab therapy. Conclusion: This review summarizes the function and effectiveness of blinatumomab in R/R and MRD positive B-ALL patients. Furthermore, blinatumomab's positive and negative aspects as a novel therapy for B-ALL patients have been briefly discussed.

Prognostic factors and impact of CMV reactivation on acute myeloid leukemia patients after HLA-matched myeloablative allogeneic stem cell transplantation in a high CMV prevalence country

ABSTRACT Introduction: Relapse of acute myeloid leukemia (AML) after allogeneic stem cell transplantation (allo-SCT) leads to dismal outcomes. This study aimed to identify high-risk patients and explore the effects of cytomegalovirus (CMV) reactivation in a high CMV-seropositive population. Methods: The study involved a single-center retrospective cohort in Thailand, analyzing clinical risk factors and CMV-mediated immune responses, correlated with transplant outcomes in AML patients. Results: Eighty-five patients with AML in complete remission (CR) undergoing HLA-matched myeloablative allo-SCT between 2011 and February 2021 were enrolled. The relapse rate was 27.1% with the median time of 7 months after transplantation. The 3-year relapse-free-survival (RFS) and overall-survival (OS) were 72.2% and 80.8%, respectively. The disease status (>CR1) and absence of chronic graft-versus-host disease (cGVHD) were independently significant adverse prognostic factors of RFS and OS. Ninety-two percent of recipient-donor pairs were both CMV seropositive. The CMV reactivation occurred in 54.1% of the patients. The clinically significant CMV infection rate was 49.4%. No CMV syndrome/disease or CMV-related mortality occurred. One-year cumulative incidence of relapse among CMV-reactivation and non-reactivation groups were 14.3% and 25.6%, respectively, without a statistically significant difference. Transplantation-related mortality was 11.1%. Conclusions: The transplantation beyond CR1 and absence of cGVHD are powerful prognostic factors associated with inferior RFS and OS. In a high CMV prevalence country, there appears to be no impact of CMV reactivation on relapse in AML patients undergoing an allo-SCT.

High dose melphalan is an adequate preparative regimen for autologous hematopoietic stem cell transplantation in relapsed/refractory lymphoma.

INTRODUCTION: High-dose melphalan (HD-Mel) has been successfully employed in autografting patients with multiple myeloma. An advantage of this regimen is that the total dose of Mel can be delivered in a single day, being particularly useful when non-frozen hematopoietic stem cells are employed in the autograft. MATERIAL AND METHODS: All consecutive patients with R/R lymphomas, both HL and NHL studied and treated at two different centers were prospectively included in a study of ASCT employing a single dose of HD-Mel (200 mg/m2). A group of R/R HL or NHL autografted employing BEAM-like preparative regimens was constructed matched by diagnosis and age. The primary endpoint of the study was overall survival (OS), the secondary endpoint was event-free survival (EFS). RESULTS: Twenty-five R/R HL/NHL patients were prospectively accrued in the study. There were 8 (32%) females, 13 (52%) patients had at least 1 adverse effect: 7 (28%) developed mucositis, 5 (20%) neutropenic fever, and 6 (24%) grade IV nausea. In the HD-Mel group, median overall survival (OS) was not achieved and OS at 36 months was 71%, the transplant-related mortality being 0%. In the control group, median OS was not achieved and the 36-month OS was 76%, results not statistically significant (p 0.5). The EFS was also similar in both groups (p 0.5). CONCLUSION: HD-Mel alone is non-inferior to a BEAM-like regimen as a preparative regimen for autografting patients with R/R HL and NHL. The regimen is adequate to graft persons with non-frozen stem cells.

Impact of rituximab in Mexican patients with Multiple Sclerosis-A single-center retrospective study.

BACKGROUND: Multiple Sclerosis (MS) is a chronic autoimmune disease of the central nervous system (CNS). B cells have an essential role in the disease pathogenesis and therefore selective B-cell depletion are commonly used to treat the disease. Rituximab (RTX), a chimeric anti-CD20 monoclonal antibody had demonstrated reduced inflammatory activity and radiological activity in MS patients. Due to economic constrains and treatment access limitations, RTX is often used as a treatment alternative in these patients. Here, we described our center experience in RTX -treated MS patients. METHODS: A single-center observational retrospective study was conducted in a Mexican cohort MS during 2010 to 2020. All patients had a confirmed MS diagnosis.All patients received fixed scheme involving induction with 1 g on day one and day 15, followed by 500 mg-1 g every six months for maintenance. Annual Relapse Rate (ARR), Progression index (PI), Expanded Disability Status Scale (EDSS) and MRI activity of the disease were evaluated. Comparison between naïve and non-naïve patients was also conducted. RESULTS: A total of 85 patients were included. The mean age at diagnosis was 33.13 (±8.90) years with 73 (85.9%) being RRMS. 39 (34.1%) were treatment-naïve. While treated with RTX, 62(72.9%) patients reached a free-of-relapse status, with statistically significant decrease in the mean ARR from 0.82 to 0.36 [0.14 (95%CI: 0.09-0.20), p = 0.0001 and EDSS [0.25 CI 0-0.5 (p = 0.034)] and a decrease in their T1 Gd-enhancing MRI lesions (1.64 vs. 0.12 CI 0.70-2.30, p = 0.004. 29 (29.4%) patients achieved NEDA-3. Among all patients, only 2 (2.4%) experienced infusion-related mild adverse events. No serious adverse events were reported. CONCLUSION: We found significant clinical and radiological improvement in naïve and non-naïve MS patients treated with RTX.

Cyclophosphamide-glucocorticoids versus lenalidomide-dexamethasone as treatment for multiple myeloma at first relapse after autologous stem cell transplantation - a retrospective analysis

ABSTRACT There have been significant improvements in therapeutic options for relapsed multiple myeloma (MM) over the past two decades, with many novel agents including proteasome inhibitors, immunomodulatory agents, and more recently monoclonal antibodies demonstrating efficacy in this setting. However, there is a paucity of real-world data comparing outcomes seen in patients treated with novel agents as opposed to older agents. We report a historical single center cohort of patients diagnosed with myeloma between the years 1991-2012 in order to explore possible differences in outcomes. A total of 139 patients who underwent stem cell transplantation were included in our study. In our study, 88 patients were treated with cyclophosphamide and steroids alone at relapse whereas 51 patients were treated with Len-Dex. In the multivariate analysis, TTNT was shorter for patients who received Cyclo compared to Len-Dex (HR = 1.74; 95% CI, 1.01-2.99; p = 0.04); however, we could not detect an overall survival benefit (HR = 1.20; 95% CI 0.63-2.29; p = 0.57). Adverse event rates were similar in the two groups. In this retrospective single center analysis, Len-Dex was associated with longer TTNT compared with Cyclo at first relapse following autoSCT in MM; however its effect on overall survival in this setting was less clear.

SOHO State of the Art Updates and Next Questions: The Past, Present and Future of Venetoclax-Based Therapies in AML.

The use of venetoclax in combination with hypomethylating agents (HMA) has changed the paradigm for the treatment of acute myeloid leukemia (AML) in elderly patients and those unfit for intensive chemotherapy. A phase 3 study has shown superior response rates and improved overall survival for patients treated with venetoclax + azacitidine compared with the previous standard of care, azacitidine alone. This success has led to multiple exciting follow-up studies, including investigations related to the discovery of predictors of response, relapse, and the mechanism of action of this therapy. While venetoclax + HMA has shown significant benefit in elderly patients unfit for chemotherapy, further questions remain as to how this therapy can be expanded into other populations including relapsed or refractory patients and younger newly diagnosed patients with adverse risk features. In this article, we discuss the clinical outcomes of AML with venetoclax + HMA, established and potential predictors of response to this regimen, its mechanisms of action, and speculate on the future of venetoclax + HMA therapy in AML.

Health-related quality of life maintained over time in patients with relapsed or refractory multiple myeloma treated with daratumumab in combination with bortezomib and dexamethasone: results from the phase III CASTOR trial.

In the phase III CASTOR trial, daratumumab, bortezomib and dexamethasone (D-Vd) significantly extended progression-free survival compared with bortezomib and dexamethasone (Vd) alone in patients with relapsed/refractory multiple myeloma (RRMM). Here, we present patient-reported outcomes (PROs) from the CASTOR trial. PROs were assessed using the European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire Core 30-item (EORTC QLQ-C30) and the EuroQol 5-dimensional descriptive system questionnaire. Treatment effects through Cycle 8 were measured by a repeated measures mixed-effects model. After Cycle 8, PROs were only collected for patients in the D-Vd group who continued on daratumumab monotherapy. Compliance rates for PRO assessments were high and similar between treatment groups. Mean changes from baseline were generally similar between treatment groups for EORTC QLQ-C30 global health status (GHS), functioning and symptoms, and did not exceed 10 points for either treatment group. Subgroup analyses were consistent with the results observed in the overall population. There was no change in patients' health-related quality of life for the first eight cycles of therapy; thereafter, patients treated with daratumumab over the long-term reported improvements in GHS and pain. These results complement the significant clinical benefits observed with D-Vd in patients with RRMM and support its use in this patient population.

Real-world outcomes for the treatment of relapsed/refractory multiple myeloma patients with lenalidomide-dexamethasone combinations in a Latin American country. A retrospective cohort study from grupo argentino de mieloma múltiple.

OBJECTIVES: We compared the efficacy of lenalidomide-dexamethasone (Rd) based treatments for relapsed/refractory multiple myeloma patients (pts), in a real-world setting. In addition, we evaluated adverse events (AE), progression-free survival (PFS) and overall survival (OS). METHODS: In our retrospective, multicentric study, 156 pts with RRMM were included. 74/156 pts (47%) were refractory to bortezomib (V) and 43/156 (27%) pts to lenalidomide (R), with 24/156 (15%) of pts double refractory. Eighty-six pts (55%) received Rd with carfilzomib (KRd), 30 pts (19%) bortezomib (VRd), 30 pts (19%) daratumumab (DRd), and 10 pts (6%) ixazomib (IRd). RESULTS: The overall response (ORR) (≥ partial response) for the entire cohort was 71%, with a very good partial response rate or better (≥VGPR) of 35%. We found no significant differences in CR or ≥VGRP rates between treatments (p:0.229). Regardless of the combination received, those patients who achieved CR had significantly improved PFS (p: 0.007). The most frequent cause of treatment discontinuation was disease progression in 55/156 pts (35%). 8 pts (5%) discontinued treatment due to treatment-related adverse events (AE). CONCLUSION: This is the first report of Rd combinations for the treatment of RRMM in Latin America. All combinations proved to be effective with an acceptable toxicity.

Treatment of relapsed/refractory multiple myeloma in the bortezomib and lenalidomide era: a systematic review and network meta-analysis.

Multiple myeloma (MM) is an incurable disease, and patients usually receive multiple lines of therapy. Due to the abundance of novel treatments for MM, we conducted a network meta-analysis to identify combinations that could fare better than others in relapsed/refractory MM, in the setting of novel drugs. We searched PubMed and Cochrane databases for phase III trials in previously treated MM that had lenalidomide or bortezomib in the control arm. The primary endpoint was progression-free survival (PFS), extracted as hazard-ratio. We used the P score to rank treatments. Thirteen studies were included. All but two studies compared one novel agent against two, with or without dexamethasone. Based on the P score, daratumumab and pegylated liposomal doxorubicin had a higher probability of achieving better PFS, followed by isatuximab, carfilzomib, pomalidomide, and panobinostat. Although most overall survival data were not mature enough, the addition of a second or third novel agent to either immunomodulatory (IMID) or proteasome inhibitor (PI) backbone seemed to improve survival (HR = 0.84, 95CI 0.77-0.92). Severe adverse events were more frequent with isatuximab, panobinostat, and pomalidomide. In summary, in the absence of trials directly comparing two novel agents-based therapies, we provide a tool that indirectly compares these newer therapies and that can help physicians to prioritize some regimens over others.

Apoptotic regulator BCL-2 blockade as a potential therapy in classical Hodgkin Lymphoma.

The challenge in classical Hodgkin Lymphoma (cHL) management is the 30-40% of refractory/relapsed cases. AIMS: The aim of this work was to determine whether NIK and BCL-2 could be useful as prognosis biomarkers in cHL. In addition, we evaluated BCL-2 as a directed-therapy in cHL cell lines using venetoclax. MAIN METHODS: We evaluated NIK and BCL-2 expression in 112 untreated cHL patients' lymph-node biopsies by immunohistochemistry. cHL cell lines were treated with venetoclax alone or combined with vincristine or doxorubicin. Cell viability, metabolic activity and cell death were analyzed by trypan-blue exclusion method, MTS assay and FDA/IP staining respectively. KEY FINDINGS: No correlation between NIK or BCL-2 expression and the majority of the clinical parameters was found. Patients with ≥60% BCL-2+ HRS-cells had a shorter disease-free survival (DFS) and overall survival (OS) (p = 0.002, p = 0.02 respectively). A decision tree analysis, in a 30 patients subgroup, showed that patients with <60% NIK+ HRS-cells but with ≥60% BCL-2+ HRS-cells had a worse outcome in terms of DFS and OS. These parameters performed better as prognosis indicators as compared to the diagnosis bone marrow status. Human cHL cell lines U-H01, KM-H2, L1236, SUPHD1, L540 showed sensitivity to venetoclax. The co-treatment effect of venetoclax and vincristine or doxorubicin on cell viability was diverse depending on the cell line evaluated. SIGNIFICANCE: BCL-2 should be considered as a prognosis biomarker as well as a potential new therapeutic target in cHL. We report for the first time the cytotoxic effect of venetoclax in human cHL cell lines.

Cyclophosphamide-glucocorticoids versus lenalidomide-dexamethasone as treatment for multiple myeloma at first relapse after autologous stem cell transplantation - a retrospective analysis.

Adverse event rates were similar in the two groups. In this retrospective single center analysis, Len-Dex was associated with longer TTNT compared with Cyclo at first relapse following autoSCT in MM; however its effect on overall survival in this setting was less clear.

Treatment of elderly patients with refractory/relapsed multiple myeloma: oral drugs adherence and the COVID-19 outbreak.

Once the treatment of refractory/relapsed multiple myeloma in the elderly is greatly influenced by the adherence of patients and family members, clinicians should be aware of patients' behavior and lifestyle, as it may influence the individual treatment plan for each patient. Furthermore, treatment with oral chemotherapy is of special value during the COVID-19 outbreak. Multidisciplinary healthcare involvement is crucial in the management of polypharmacy, adverse events and dose adjustment due to comorbidities and natural loss of renal function with age. Oral drugs simplify intake, reduce hospital visits, and improve autonomy and quality of life. However, although oral drugs have advantages, they also transfer control and responsibility from the healthcare professional to the patient, who must be able to understand and follow the directions given. Therefore, patient education and communication with healthcare professionals are critical for adherence.

Treatment of Acute Lymphoid Leukemia Refractory to Classic First-Line and Rescue Protocols.

Acute Lymphoblastic Leukemia is a very aggressive malignant disorder of lymphoid cells in adults, with recurrence (30 to 60% of the cases) after the initial treatment. Until this moment, there is no gold standard therapy for the treatment of adult patients with acute relapsed/refractory lymphoblastic leukemia. In this case report, we describe two cases of relapsed leukemia: one of lymphocytic leukemia B and one of trilineage leukemia, which presented a satisfactory response to treatment with Bortezomib associated with Vincristine, Dexamethasone, and Bendamustine.

Relapse or refractory Hodgkin lymphoma: determining risk of relapse or progression after autologous stem-cell transplantation.

The treatment of classic Hodgkin lymphoma (HL) is a success in onco-hematology. Despite the high cure rate of HL with initial therapy, 5-10% of patients are primary refractory and 10-20% will eventually relapse. The standard treatment for these patients is salvage chemotherapy and autologous stem cell transplantation (ASCT). Only about half of these patients will benefit from this procedure. The prognosis of relapsed refractory (rr) HL has improved with the introduction of effective drugs. With these options available, identification of reliable risk factors is important to guide treatment over the course of disease. Different variables including performance status, anemia, B symptoms, laboratory abnormalities, treatment intensity before ASCT, response to therapy, and duration of remission, have been analyzed to determine risk for progression-free survival (PFS) and overall survival (OS) after ASCT. This review will discuss the publications analyzing these factors, the validated risk scores useful to identify patients at high risk of progression after ASCT, and will describe future perspectives.

Comparison of clinical remission and survival between CLAG and FLAG induction chemotherapy in patients with refractory or relapsed acute myeloid leukemia: a prospective cohort study.

PURPOSE: To compare the clinical remission and survival between CLAG and FLAG induction chemotherapy in treating patients with refractory or relapsed acute myeloid leukemia (R/R AML). METHODS: 103 R/R AML patients were consecutively enrolled in this prospective cohort study. 55 patients were treated by CLAG induction chemotherapy as follows: 5 mg/m2/day cladribine (days 1-5); 2 g/m2/day cytarabine (days 1-5) and 300 µg/day filgrastim (days 0-5). While 48 patients were treated by FLAG: 30 mg/m2/day fludarabine (days 1-5), 2 g/m2/day cytarabine (days 1-5), and 300 µg/day filgrastim (days 0-5). RESULTS: CLAG induction chemotherapy achieved 61.7% complete remission rate (CR) and 78.7% overall remission rate (ORR), which was similar with FLAG chemotherapy which realized 48.7% CR and 69.2% ORR. No difference of overall survival (OS) was discovered between two groups either. Age cytarabine 60 years, secondary disease, poor risk stratification and BM blast ≥ 42.7% and second or higher salvage therapy were independent factors for worse prognosis. Subgroups analysis revealed that in patients with second or higher salvage therapy, CLAG seemed to achieve a higher CR than FLAG. And in patients with relapsed disease, poor risk stratification or CR at first induction, CLAG seemed to realize a prolonged OS compared to FLAG. CONCLUSION: CLAG was equally effective to FLAG induction chemotherapy in total R/R AML patients, while CLAG seemed to be a better option than FLAG in patients with relapsed disease, poor risk stratification, CR at first induction or second or higher salvage therapies.

Cost-effectiveness analysis of sensitive relapsed small-cell lung cancer based on JCOG0605 trial.

PURPOSE: Since combined strategy with cisplatin, etoposide, and irinotecan has shown the superiority to topotecan alone as second-line chemotherapy in patients with sensitive relapsed small-cell lung cancer, this study aimed to compare these two treatments based on JCOG0605 trail from Chinese cost-effectiveness perspective. METHODS: Basic medical information was derived from a multicenter, open-label, randomized phase III trial (JCOG0605). A Markov model including three health states: progression-free state, progressive disease (PD), and death, was developed to simulate the process of sensitive relapsed small-cell lung cancer. Cost was calculated from the perspective of Chinese society. Sensitivity analyses were applied to explore the impact of essential variables. RESULTS: Treatment with combination chemotherapy was estimated to increase costs by $6947.32 compared with topotecan alone, with a gain of 0.26 quality-adjusted life years (QALYs). Thus, the incremental cost-effective ratio was $26720.46/QALY for combination treatment versus monotherapy, which was beyond the threshold of 3 × the per capita GDP of China, $24423.00. The costs of PD state were the most influential factors to the model. CONCLUSION: The combination chemotherapy with cisplatin, etoposide, and irinotecan was not a cost-effectiveness choice for patients with sensitive relapsed SCLC in China from the cost-effectiveness perspective.
