Short regimen of rituximab plus lenalidomide in follicular lymphoma patients in need of first-line therapy.

The SAKK 35/10 phase 2 trial, developed by the Swiss Group for Clinical Cancer Research and the Nordic Lymphoma Group, compared the activity of rituximab vs rituximab plus lenalidomide in untreated follicular lymphoma patients in need of systemic therapy. Patients were randomized to rituximab (375 mg/m2 IV on day 1 of weeks 1-4 and repeated during weeks 12-15 in responding patients) or rituximab (same schedule) in combination with lenalidomide (15 mg orally daily for 18 weeks). Primary end point was complete response (CR)/unconfirmed CR (CRu) rate at 6 months. In total, 77 patients were allocated to rituximab monotherapy and 77 to the combination (47% poor-risk Follicular Lymphoma International Prognostic Index score in each arm). A significantly higher CR/CRu rate at 6 months was documented in the combination arm by the investigators (36%; 95% confidence interval [CI], 26%-48% vs 25%; 95% CI, 16%-36%) and confirmed by an independent response review of computed tomography scans only (61%; 95% CI, 49%-72% vs 36%; 95% CI, 26%-48%). After a median follow-up of 4 years, significantly higher 30-month CR/CRu rates and longer progression-free survival (PFS) and time to next treatment (TTNT) were observed for the combination. Overall survival (OS) rates were similar in both arms (≥90%). Toxicity grade ≥3 was more common in the combination arm (56% vs 22% of patients), mainly represented by neutropenia (23% vs 7%). Addition of lenalidomide to rituximab significantly improved CR/CRu rates, PFS, and TTNT, with expected higher, but manageable toxicity. The excellent OS in both arms suggests that chemotherapy-free strategies should be further explored. This trial was registered at www.clinicaltrials.gov as #NCT01307605.

Prolonged survival after second autologous transplantation and lenalidomide maintenance for salvage treatment of myeloma patients at first relapse after prior autograft.

Autologous stem cell transplantation (ASCT) as part of the primary therapy in multiple myeloma (MM) is standard practice. In contrast, the role of a second ASCT (ASCT2) and subsequent lenalidomide maintenance for relapsed disease remains unclear. In this study, we analysed 86 consecutive MM patients with a first relapse after prior ASCT receiving either a second ASCT or conventional chemotherapy. After a median follow-up of 37.7 months since first relapse, 54 (62.8%) patients were still alive and 29 (33.7%) without progression. Sixty-one (71.0%) patients received ASCT2 and had better progression-free survival (PFS) (30.2 versus 13.0 mo; P = .0262) and overall survival (OS) rates (129.6 versus 33.5 mo; P = .0003) compared with 25 (29.0%) patients with conventional treatment. Patients relapsing later than 12 months after ASCT1 benefitted from a second ASCT with better PFS2 (P = .0179) and OS2 (P = .0009). Finally, lenalidomide maintenance after ASCT2 was associated with longer PFS (41.0 vs 21.6 mo; P = .0034) and better OS (not yet reached vs 129.6 mo; P = .0434) compared with patients without maintenance. Our data suggest that a second ASCT and lenalidomide maintenance given at first relapse in MM after prior ASCT are associated with better survival rates.

BeEAM conditioning with bendamustine-replacing BCNU before autologous transplantation is safe and effective in lymphoma patients.

BEAM with BCNU is commonly used for conditioning treatment followed by autologous stem cell transplantation (ASCT). However, pulmonary toxicity and availability issues associated with BCNU prompted us to evaluate bendamustine-replacing BCNU (BeEAM). We analyzed 39 lymphoma patients receiving BeEAM conditioning with 200 mg/m2 bendamustine at days -7 and -6. The median duration until neutrophil recovery was 11 days, and 15 days for platelet recovery (>20 g/L). The most common grade 3/4 non-hematologic toxicities comprised mucosal side effects (27 pts.). Pulmonary toxicity was observed in one patient (2.5%), and one patient died of septic complications. The CR rate increased from 33% to 74% 100 days after ASCT. After a median follow-up of 18.5 months, progression and death each occurred in 11 patients (28%). Median progression-free and overall survival at 2 years were 69% and 72%. Our data suggest that BeEAM conditioning using bendamustine is safe and results in promising survival rates.

BeEAM Conditioning including High-Dose Bendamustine before Autologous Stem Cell Transplantation Is Safe and Effective in Patients with Waldenstrom's Macroglobulinemia.

High-dose chemotherapy (HDCT) with autologous stem cell transplantation (ASCT) is an option to consolidate remission in Waldenstrom's macroglobulinemia (WM), particularly in selected younger patients with chemosensitive disease. BEAM, consisting of BCNU, etoposide, cytarabine, and melphalan, is often used as a conditioning regimen. However, problems with BCNU, including pneumotoxicity, tolerance, and availability, necessitate the search for alternatives. In this pilot study, we investigated high-dose chemotherapy with BeEAM, in which BCNU is replaced with high-dose bendamustine as an alternative conditioning regimen in six subsequent patients with WM. Bendamustine treatment was well tolerated without unexpected toxicities. The overall response rate was 6/6 patients (2 very good partial responses (VGPR) and 4 PR). After a median follow-up of 72 months, two (33%) patients relapsed. Median progression-free and overall survivals were not reached, and no severe late-onset toxicities were observed so far. In this pilot study, BeEAM conditioning before ASCT seems feasible, safe, and effective in patients with WM.

Combined therapy with ibrutinib and bortezomib followed by ibrutinib maintenance in relapsed or refractory mantle cell lymphoma and high-risk features: a phase 1/2 trial of the European MCL network (SAKK 36/13).

Background: The Bruton's tyrosine kinase inhibitor ibrutinib and the proteasome inhibitor bortezomib have single-agent activity, non-overlapping toxicities, and regulatory approval in mantle cell lymphoma (MCL). In vitro, their combination provides synergistic cytotoxicity. In this investigator-initiated phase 1/2 trial, we established the recommended phase 2 dose of ibrutinib in combination with bortezomib, and assessed its efficacy in patients with relapsed or refractory MCL. Methods: In this phase 1/2 study open in 15 sites in Switzerland, Germany and Italy, patients with relapsed or refractory MCL after ≤2 lines of chemotherapy and both ibrutinib-naïve and bortezomib-naïve received six cycles of ibrutinibb and bortezomib, followed by ibrutinib maintenance. For the phase 1 study, a standard 3 + 3 dose escalation design was used to determine the recommended phase 2 dose of ibrutinib in combination with bortezomib. The primary endpoint in phase 1 was the dose limiting toxicities in cycle 1. The phase 2 study was an open-label, single-arm trial with a Simon's two-stage min-max design, with a primary endpoint of overall response rate (ORR) assessed by CT/MRI. This study was registered with ClinicalTrials.gov, NCT02356458. Findings: Between August 2015 and September 2016, nine patients were treated in the phase 1 study, and 49 patients were treated between November 2016 and March 2020 in the phase 2 of the trial. The ORR was 81.8% (90% CI 71.1, 89.8%, CR(u) 21.8%) which increased with continued ibrutinib (median 10.6 months) to 87.3%, (CR(u) 41.8%). 75.6% of patients had at least one high-risk feature (Ki-67 > 30%, blastoid or pleomorphic variant, p53 overexpression, TP53 mutations and/or deletions). In these patients, ibrutinib and bortezomib were also effective with an ORR of 74%, increasing to 82% during maintenance. With a median follow-up of 25.4 months, the median duration of response was 22.7, and the median PFS was 18.6 months. PFS reached 30.8 and 32.9 months for patients with a CR or Cru, respectively. Interpretation: The combination of ibrutinib and bortezomib shows durable efficacy in patients with relapsed or refractory MCL, also in the presence of high-risk features.

Partial response to dabrafenib and trametinib in relapsed BRAF V600E-Mutated multiple myeloma and possible mechanisms of resistance.

BRAF V600E mutations are detected in 3%-10% of patients with multiple myeloma (MM) and are associated with more aggressive disease, higher frequency of extramedullary growth and shorter survival. Monotherapy with the BRAF inhibitor vemurafenib has been disappointing in MM. In patients with BRAF-mutated melanoma, MEK and BRAF inhibition has been a successful approach. Here we describe a very good partial response and possible mechanisms of resistance to a combination of the BRAF inhibitor dabrafenib and the MEK inhibitor trametinib in a patient with BRAF V600E-mutant refractory MM.

Satraplatin Demonstrates High Cytotoxic Activity Against Genetically Defined Lymphoid Malignancies.

BACKGROUND/AIM: Satraplatin is an oral platinum analog with proven clinical efficacy and a more favorable toxicity profile, although with increased hematotoxicity, when compared to cisplatin. Hence, we carried out a systematic biomarker analysis to identify hematological malignancies with high susceptibility to satraplatin. MATERIALS AND METHODS: Half-maximal inhibitory concentrations (IC50) for satraplatin and cisplatin were determined for 66 different cancer cell lines by CTG Luminescent Cell Viability Assay. In a second step, whole transcriptome RNA sequencing and whole-exome DNA sequencing technology followed by unbiased analysis of gene expression, gene mutation and copy number levels were performed and correlated with drug efficacy. RESULTS: Satraplatin was significantly more active against hematological malignancies compared to solid organ cancer. In addition, satraplatin showed a significantly more potent antiproliferative activity compared to cisplatin in most lymphoma cell lines achieving sub micromolar IC50 values. Single BCL2 apoptosis regulator (BCL2) gene mutation and 9p21 copy-number deletions including S-methyl-5'-thioadenosine phosphorylase (MTAP) deficiency were identified as key characteristics for high sensitivity to satraplatin. CONCLUSION: Satraplatin demonstrated a high cytotoxic activity in genetically well-defined hematological malignancies which is distinct from that of cisplatin. MTAP deficiency was identified as biomarker of enhanced satraplatin efficacy in hematological cancer-derived cell lines. These data in combination with the lipophilicity of satraplatin provide the rationale for targeting specific lymphatic entities such as primary central nervous system lymphoma and cutaneous T-cell lymphoma to improve clinical outcome.

Blinatumomab in Relapsed/Refractory Burkitt Lymphoma.

In patients with relapsed/refractory Burkitt lymphoma (r/r BL), overall survival (OS) is poor, and effective therapies and evidence for the best therapy are lacking. The monoclonal antibody blinatumomab may represent a novel option. However, only limited data on the use of blinatumomab in r/r BL are so far available. This multi-center, retrospective case series investigated nine patients with r/r BL treated with blinatumomab. The safety of blinatumomab was assessed with respect to frequency and severity of adverse effects (AEs) infections, cytokine release syndrome (CRS) and neurotoxicity. Progression-free survival (PFS), OS and overall response rate (ORR) were analyzed to assess efficacy. No AEs > grade 2 occurred, and AEs were generally treatable and fully reversible. The best response to blinatumomab was complete remission in 3/9 patients and partial remission in 2/9, whilst 4/9 presented with progressive disease. Median PFS and OS were 2 and 6 months, respectively, ranging from 5 days to 32 months and 11 days to 32 months, respectively. Blinatumomab treatment was a successful bridging treatment to stem cell transplantation in 3/9 patients. The response to blinatumomab varied widely, and only one patient survived longer term, but activity in patients with r/r BL was evident in some patients, with its use being safe, warranting its prospective investigation.

Adding bendamustine to melphalan before ASCT improves CR rate in myeloma vs. melphalan alone: A randomized phase-2 trial.

Definite cure remains exceptional in myeloma patients even after high-dose chemotherapy (HDCT) with melphalan (Mel) and autologous stem cell transplantation (ASCT). Thus, improving efficacy of HDCT in MM remains an unresolved issue. This randomized phase II trial compared standard 200 mg/m2 Mel HDCT to experimental HDCT with 200 mg/m2 bendamustine, given both at days -4 and -3, combined with 100 mg/m2 melphalan at days -2 and -1 (BenMel) before ASCT as first-line consolidation in myeloma patients. The primary endpoint aimed to identify at least a 15% improvement in the complete remission rate (stringent CR + CR) after HDCT with BenMel compared with Mel alone. A total of 120 MM patients were 1:1 randomized. The rate of sCR/CR after ASCT was higher in BenMel than in Mel treated patients (70.0% vs. 51.7%; p = 0.039). Three patients in the BenMel group (5.0%) had reversible acute renal insufficiency compared with none in Mel patients. Minimal residual disease negativity (<10-5) by flow cytometry was observed in 26 (45.6%) BenMel patients and 22 (37.9%) in the Mel group (p = 0.375). Our data suggest that BenMel HDCT is safe and improves the sCR/CR rate compared with standard Mel alone.

Clinical outcome with bevacizumab in patients with recurrent high-grade glioma treated outside clinical trials.

BACKGROUND: Patients with recurrent high-grade glioma (HGG) have a poor prognosis and there is no defined standard of care. High levels of vascular endothelial growth factor (VEGF) expressed in HGG make the anti-VEGF monoclonal antibody bevacizumab (BEV) of particular interest. PATIENTS AND METHODS: In an ongoing registry data were collected from patients who have received BEV for the treatment of recurrent HGG. The primary objective was the identification of any clinical benefit as assessed by change in Karnofsky Performance Score (KPS), decreased steroid use and duration of treatment. RESULTS: Two hundred and twenty-five patients with HGG were included (176 glioblastoma; 49 anaplastic glioma; median age 52 years). KPS improved in 10% of patients and remained stable in 68%. Steroids were stopped in 37.6% of patients. Median duration of treatment was 5.5 months; 19.1% of patients were treated for more than 12 months. Median overall survival from beginning of BEV treatment was 8.5 months. At the time of analysis, 169 patients (75.1%) had died and 56 patients (24.9%) were alive. Only 21 patients (9.3%) discontinued treatment due to toxicity. CONCLUSIONS: Our data reveal valuable palliation with preservation of KPS and an option for steroid withdrawal in patients treated with BEV, supporting the role of this therapy in late-stage disease.

Consolidation and Maintenance in Newly Diagnosed Multiple Myeloma.

PURPOSE: To address the role of consolidation treatment for newly diagnosed, transplant eligible patients with multiple myeloma in a controlled clinical trial. PATIENTS AND METHODS: The EMN02/HOVON95 trial compared consolidation treatment with two cycles of bortezomib, lenalidomide, and dexamethasone (VRD) or no consolidation after induction and intensification therapy, followed by continuous lenalidomide maintenance. Primary study end point was progression-free survival (PFS). RESULTS: Eight hundred seventy-eight eligible patients were randomly assigned to receive VRD consolidation (451 patients) or no consolidation (427 patients). At a median follow-up of 74.8 months, median PFS with adjustment for pretreatment was prolonged in patients randomly assigned to VRD consolidation (59.3 v 42.9 months, hazard ratio [HR] = 0.81; 95% CI, 0.68 to 0.96; P = .016). The PFS benefit was observed across most predefined subgroups, including revised International Staging System (ISS) stage, cytogenetics, and prior treatment. Revised ISS3 stage (HR, 2.00; 95% CI, 1.41 to 2.86) and ampl1q (HR, 1.67; 95% CI, 1.37 to 2.04) were significant adverse prognostic factors. The median duration of maintenance was 33 months (interquartile range 13-86 months). Response ≥ complete response (CR) after consolidation versus no consolidation before start of maintenance was 34% versus 18%, respectively (P < .001). Response ≥ CR on protocol including maintenance was 59% with consolidation and 46% without (P < .001). Minimal residual disease analysis by flow cytometry in a subgroup of 226 patients with CR or stringent complete response or very good partial response before start of maintenance demonstrated a 74% minimal residual disease-negativity rate in VRD-treated patients. Toxicity from VRD was acceptable and manageable. CONCLUSION: Consolidation treatment with VRD followed by lenalidomide maintenance improves PFS and depth of response in newly diagnosed patients with multiple myeloma as compared to maintenance alone.

Autologous haematopoietic stem-cell transplantation versus bortezomib-melphalan-prednisone, with or without bortezomib-lenalidomide-dexamethasone consolidation therapy, and lenalidomide maintenance for newly diagnosed multiple myeloma (EMN02/HO95): a multicentre, randomised, open-label, phase 3 study.

BACKGROUND: The emergence of highly active novel agents has led some to question the role of autologous haematopoietic stem-cell transplantation (HSCT) and subsequent consolidation therapy in newly diagnosed multiple myeloma. We therefore compared autologous HSCT with bortezomib-melphalan-prednisone (VMP) as intensification therapy, and bortezomib-lenalidomide-dexamethasone (VRD) consolidation therapy with no consolidation. METHODS: In this randomised, open-label, phase 3 study we recruited previously untreated patients with multiple myeloma at 172 academic and community practice centres of the European Myeloma Network. Eligible patients were aged 18-65 years, had symptomatic multiple myeloma stage 1-3 according to the International Staging System (ISS), measurable disease (serum M protein >10 g/L or urine M protein >200 mg in 24 h or abnormal free light chain [FLC] ratio with involved FLC >100 mg/L, or proven plasmacytoma by biopsy), and WHO performance status grade 0-2 (grade 3 was allowed if secondary to myeloma). Patients were first randomly assigned (1:1) to receive either four 42-day cycles of bortezomib (1·3 mg/m2 administered intravenously or subcutaneously on days 1, 4, 8, 11, 22, 25, 29, and 32) combined with melphalan (9 mg/m2 administered orally on days 1-4) and prednisone (60 mg/m2 administered orally on days 1-4) or autologous HSCT after high-dose melphalan (200 mg/m2), stratified by site and ISS disease stage. In centres with a double HSCT policy, the first randomisation (1:1:1) was to VMP or single or double HSCT. Afterwards, a second randomisation assigned patients to receive two 28-day cycles of consolidation therapy with bortezomib (1·3 mg/m2 either intravenously or subcutaneously on days 1, 4, 8, and 11), lenalidomide (25 mg orally on days 1-21), and dexamethasone (20 mg orally on days 1, 2, 4, 5, 8, 9, 11, and 12) or no consolidation; both groups received lenalidomide maintenance therapy (10 mg orally on days 1-21 of a 28-day cycle). The primary outcomes were progression-free survival from the first and second randomisations, analysed in the intention-to-treat population, which included all patients who underwent each randomisation. All patients who received at least one dose of study drugs were included in the safety analyses. This study is registered with the EU Clinical Trials Register (EudraCT 2009-017903-28) and ClinicalTrials.gov (NCT01208766), and has completed recruitment. FINDINGS: Between Feb 25, 2011, and April 3, 2014, 1503 patients were enrolled. 1197 patients were eligible for the first randomisation, of whom 702 were assigned to autologous HSCT and 495 to VMP; 877 patients who were eligible for the first randomisation underwent the second randomisation to VRD consolidation (n=449) or no consolidation (n=428). The data cutoff date for the current analysis was Nov 26, 2018. At a median follow-up of 60·3 months (IQR 52·2-67·6), median progression-free survival was significantly improved with autologous HSCT compared with VMP (56·7 months [95% CI 49·3-64·5] vs 41·9 months [37·5-46·9]; hazard ratio [HR] 0·73, 0·62-0·85; p=0·0001). For the second randomisation, the number of events of progression or death at data cutoff was lower than that preplanned for the final analysis; therefore, the results from the second protocol-specified interim analysis, when 66% of events were reached, are reported (data cutoff Jan 18, 2018). At a median follow-up of 42·1 months (IQR 32·3-49·2), consolidation therapy with VRD significantly improved median progression-free survival compared with no consolidation (58·9 months [54·0-not estimable] vs 45·5 months [39·5-58·4]; HR 0·77, 0·63-0·95; p=0·014). The most common grade ≥3 adverse events in the autologous HSCT group compared to the VMP group included neutropenia (513 [79%] of 652 patients vs 137 [29%] of 472 patients), thrombocytopenia (541 [83%] vs 74 [16%]), gastrointestinal disorders (80 [12%] vs 25 [5%]), and infections (192 [30%] vs 18 [4%]). 239 (34%) of 702 patients in the autologous HSCT group and 135 (27%) of 495 in the VMP group had at least one serious adverse event. Infection was the most common serious adverse event in each of the treatment groups (206 [56%] of 368 and 70 [37%] of 189). 38 (12%) of 311 deaths from first randomisation were likely to be treatment related: 26 (68%) in the autologous HSCT group and 12 (32%) in the VMP group, most frequently due to infections (eight [21%]), cardiac events (six [16%]), and second primary malignancies (20 [53%]). INTERPRETATION: This study supports the use of autologous HSCT as intensification therapy and the use of consolidation therapy in patients with newly diagnosed multiple myeloma, even in the era of novel agents. The role of high-dose chemotherapy needs to be reassessed in future studies, in particular in patients with undetectable minimal residual disease after four-drug induction regimens including a monoclonal antiboby combined with an immunomodulatory agent and a proteasome inhibitor plus dexamethasone.

Updated recommendations for diagnosis and treatment of plasma cell myeloma in Switzerland.

This update on plasma cell myeloma has been elaborated by a Swiss expert panel as a result of the plethora of new data on the treatment of plasma cell myeloma reported recently. It adds new insights to the more extensive review that was published 3 years ago and may help clinicians on decision making for their patients. The new recommendations for distinguishing plasma cell myeloma from smouldering myeloma are briefly presented, including a section on contemporary imaging studies with this respect. Former panel recommendations that remain unchanged by new results will not be discussed in detail as the major focus of this review is on treatment-relevant new developments.

Diagnosis and treatment of follicular lymphoma: an update.

Over the last few years, there have been many changes in the management of patients with follicular lymphoma, resulting in improvements in progression-free survival and quality of life. In addition to established regimens such as radiotherapy and immunochemotherapy, new treatment options are on the horizon. Furthermore, even the use of established chemotherapy agents has evolved, with new combinations moving to the forefront of the current treatment strategy. Nevertheless, there remains an unmet need for patients who have early relapses, those who are not responsive to anti-CD20 treatment regimens and for those in whom minimal residual disease persists even after immunochemotherapy. This review provides a summary of current developments in the diagnosis, treatment and management of follicular lymphoma, focusing on the clinical issues from a Swiss perspective.

Gastric pneumatosis following polychemotherapy.

Lung cancer is the most frequent cause of cancer deaths in the western world today. In our case, we present the history of a 62-year-old man with the diagnosis of the uncommon complication of an acute gastric pneumatosis following his palliative chemotherapy. This rare condition was first described more than 100 years ago and has since been described in several distinctive clinical settings. To our knowledge, we present the first case of chemotherapy-related pneumatosis exclusively limited to the stomach wall but involving the portal veins and the spleen.

Bevacizumab Plus Pemetrexed Versus Pemetrexed Alone as Maintenance Therapy for Patients With Advanced Nonsquamous Non-Small-cell Lung Cancer: Update From the Swiss Group for Clinical Cancer Research (SAKK) 19/09 Trial.

BACKGROUND: Pemetrexed and bevacizumab as single agents have been approved for maintenance therapy after platinum-based induction in patients with advanced nonsquamous non-small-cell lung cancer. It is currently unknown whether bevacizumab plus pemetrexed is superior to pemetrexed alone. PATIENTS AND METHODS: We conducted a nonrandomized phase II trial with 2 sequential cohorts. In the first cohort, 77 patients were treated with 4 cycles of cisplatin, bevacizumab, and pemetrexed every 3 weeks, followed by bevacizumab plus pemetrexed maintenance until progression. In the second cohort, we treated 52 patients without bevacizumab, using maintenance with pemetrexed alone. Progression-free survival (PFS), overall survival (OS), overall response rate (ORR), adverse events, and the treatment costs of the 2 cohorts were compared. RESULTS: The median PFS from the time of registration was 6.9 months in cohort 1 and 5.6 months in cohort 2. The ORR was 62.3% in cohort 1% and 44.2% in cohort 2. The PFS (hazard ratio, 0.7; 95% confidence interval [CI], 0.5-1.0; P = .041) and ORR (odds ratio, 2.1; 95% CI, 1.0-4.3; P = .049) were better in cohort 1 than in cohort 2. No OS difference was found (hazard ratio, 1.0; 95% CI, 0.7-1.6; P = .890) after a median follow-up period of 47 months for cohort 1 and 27 months for cohort 2. The rate of grade ≥ 3 adverse events was greater in cohort 1. The treatment costs per patient were on average 1.4 times greater for cohort 1. CONCLUSION: The addition of bevacizumab increased the ORR and PFS, but not OS, in our nonrandomized trial. Furthermore, the addition of bevacizumab was associated with greater toxicity and higher costs.

Current status and updated recommendations for diagnosis and treatment of plasma cell myeloma in Switzerland.

The availability of drugs such as thalidomide, bortezomib and lenalidomide changed the landscape in myeloma treatment and has extended the median survival up to 10 years with a substantial improvement in quality of life. This development prompted a Swiss expert panel to re-evaluate the current status and formulate updated clinical recommendations for the diagnosis and treatment of plasma cell myeloma. These recommendations should help clinicians in their decision making to achieve the best outcome based on currently available data.
