RESUMEN
BACKGROUND: Prognosis of patients with multiple myeloma (MM) who have relapsed on or become refractory to immunomodulators and bortezomib is poor, and treatment options are limited. While pomalidomide plus low-dose dexamethasone (POM/DEX) has demonstrated efficacy in clinical trials, real-world evidence is scarce. PATIENTS AND METHODS: POSEIDON was a prospective non-interventional study designed to evaluate effectiveness, safety and quality of life (QoL) of POM/DEX in patients with relapsed or refractory MM (R/RMM) pretreated with at least two prior therapy lines including both lenalidomide and bortezomib in real world in Germany. Patients received POM/DEX according to physicians' choice. Data were analyzed descriptively. RESULTS: Between 2014 and 2017, 151 patients were enrolled, 144 patients with a median of three prior therapy lines qualified for effectiveness analysis. Median age was 73.2 years. Median progression-free and overall survival were 6.3 months [95% confidence interval (CI) 5.2, 8.6] and 12.9 months [95% CI 10.6, 15.1]. Most frequent grade 3/4 adverse events were leukopenia (8.2%), pneumonia (7.5%) and anemia (5.5%). QoL was maintained after start of POM/DEX. CONCLUSION: The results of POSEIDON support the effectiveness and safety of POM/DEX in R/RMM patients pretreated with lenalidomide and bortezomib and highlight the clinical value of the POM/DEX regimen in the real-world setting.

Few data exist on health-related quality of life (QoL) in patients with metastatic pancreatic cancer (mPC) receiving first-line chemotherapy (Awad L ZE, Mesbah M Boston, MA. Applying survival data methodology to analyze quality of life data, in Mesbah M, Cole BF, Ting Lee M-L (eds): Statistical Methods for Quality of Life Studies: Design, Measurements and Analysis. Kluwer Academic Publishers 2002). The QOLIXANE study is a prospective, noninterventional, multicenter substudy of the Platform for Outcome, Quality of Life and Translational Research on Pancreatic Cancer (PARAGON) registry, which evaluated QoL in patients with mPC receiving first-line gemcitabine and nab-paclitaxel chemotherapy in real-life setting. QoL was prospectively measured via EORTC QLQ-C30 questionnaires at baseline and every month thereafter. Therapy and efficacy parameters were prospectively collected. Main objectives were the rate of patients without deterioration of Global Health Status/QoL (GHS/QoL) at 3 and 6 months. Six hundred patients were enrolled in 95 German study sites. Median progression-free survival was 5.9 months (95% confidence interval [CI], 5.2-6.3). Median overall survival (OS) was 8.9 months (95% CI, 7.9-10.2), while median time to deterioration of GHS/QoL was 4.7 months (95% CI, 4.0-5.6). With a baseline GHS/QoL score of 46 (SD, 22.8), baseline QoL of the patients was severely impaired, in most cases due to loss in role functioning and fatigue. In the Kaplan-Meier analysis, 61% and 41% of patients had maintained GHS/QoL after 3 and 6 months, respectively. However, in the QoL response analysis, 35% and 19% of patients had maintained (improved or stable) GHS/QoL after 3 and 6 months, respectively, while 14% and 9% had deteriorated GHS/QoL with the remaining patients being nonevaluable. In the Cox regression analysis, GHS/QoL scores strongly predicted survival with a hazard ratio of 0.86 (P < .0001). Patients with mPC have poor QoL at baseline that deteriorates within a median of 4.7 months. Treatment with gemcitabine and nab-paclitaxel is associated with maintained QoL in relevant proportions of patients. However, overall, results remain poor, reflecting the aggressive nature of the disease.

OBJECTIVE: Real-world evidence on the application of the granulocyte colony-stimulating factor lipegfilgrastim for the reduction of chemotherapy-induced neutropenia and febrile neutropenia (FN) is limited. The NADIR study aimed to evaluate effectiveness and safety of lipegfilgrastim as primary or secondary prophylaxis in patients with lung cancer undergoing chemotherapy in routine clinical practice. METHODS: The non-interventional study NADIR (German Clinical Trials Register (DRKS) Number DRKS00005711) enrolled 156 patients with small-cell lung cancer (SCLC) and 145 patients with non-small-cell lung cancer (NSCLC), who received lipegfilgrastim during chemotherapy. Primary endpoint was the incidence of severe neutropenia (CTCAE grade 3/4) and FN. The analysis was stratified for age groups (≤65 years vs. >65 years). RESULTS: Approximately half of the patients were aged >65 years (SCLC 54.5%; NSCLC 46.9%). Intention of antineoplastic treatment was mostly palliative (SCLC 89.1%; NSCLC 73.1%). Patients with high FN risk (SCLC 44.9%; NSCLC 28.3%) mostly received lipegfilgrastim for primary prophylaxis (SCLC 81.4%; NSCLC 70.7%). FN was reported in 1.9% SCLC and 1.4% NSCLC patients. At least one severe neutropenia was documented in 30.1% SCLC and 17.9% NSCLC patients. For NSCLC patients aged >65 years, less severe neutropenia was reported as compared to younger patients (14.7% vs. 20.8%). Lipegfilgrastim-related adverse events were reported in 10.3% SCLC and 7.7% NSCLC patients. CONCLUSION: Lipegfilgrastim in routine clinical practice of patients with lung cancer showed similar effectiveness and safety as compared to the pivotal trial. Interestingly, in older patients severe neutropenia was reported less frequently. While most patients with high FN risk received lipegfilgrastim for primary prophylaxis as recommended, there are still 20-30% of patients at high FN risk without primary prophylaxis who could benefit from better adherence to guidelines.

INTRODUCTION: This is a single-arm study (NCT01956149) to determine the prolonged (≥ 4 months) disease control rate with cabazitaxel administered in second-(or later) setting for patients with advanced or metastatic adenocarcinoma of the esophagogastric junction (EGJ) and stomach. METHODS: 65 patients with advanced EGJ and stomach cancer were treated with 20 mg/m2 cabazitaxel every 3 weeks for a maximum of six cycles. The main objective of the study is a prolonged disease control rate (pDCR: CR, PR or SD lasting at least 4 months). Secondary outcome measures were overall survival, progression-free survival, response rate by subgroup (with vs without previous treatment with a taxane) and toxicity. Patients were assessed for tumor response every 6 weeks during therapy and during the follow-up (up to 12 months). RESULTS: 65 patients (median age: 63, range 31-86 years) were assigned to treatment. Median no. of prior therapies that had received prior taxane therapy was 2. 80%. Patients received a median of two cycles of cabazitaxel. Efficacy results are for the ITT population. The mDCR in n = 65 patients was 10.8% (95% CI 4.4-20.9%). There was a control of disease (CR + PR + SD) in n = 26 patients of n = 65, corresponding to a DCR of 40.0% (95% CI 28.0-52.9%). In patients without prior taxane use, it was 46.2% (95% CI 25.1-80.8%) and in patients with only one prior therapy, DCR was 50.0% (95% CI 31.3-68.7%). The median overall survival was 4.6 months (95% CI 3.16, 5.59) in the whole ITT population. In patients with only one prior therapy, median OS was 5.4 months (95% CI 2.60, 7.43) and in patients without taxane pretreatment, it was 6.4 months (95% CI 1.38, 14.17). The median progression-free survival time was 1.5 months (95% CI 1.32, 2.27) in the whole ITT population, 2.9 months (95% CI 0.72, 4.67) without prior taxane therapy and was 1.7 (95% CI 1.28, 3.35) months in patients with only one prior therapy median. CONCLUSIONS: Cabazitaxel is active in heavily pretreated patients with metastatic and advanced esophagogastric junction and gastric adenocarcinoma. Efficacy results in a classic second-line population are comparable to other second-line studies, therefore, under the limitations of this trial, (single arm, Phase II design) cabazitaxel might be an option especially in patients without prior taxane therapy, in second line and even further line therapy of metastatic and advanced esophagogastric junction and gastric adenocarcinoma.

The therapy of patients with relapsed or refractory indolent lymphoma relies on the development of new drug combinations. The drugs bendamustine and fludarabine have cytotoxic activity as monotherapy in indolent lymphoma and show synergism in vitro. In this study, we combined both drugs in a multicenter clinical phase I/II trial to evaluate their toxicity and efficacy. Bendamustine was given at 30 or 40 mg/m2/d (dose levels 1 and 2), fludarabine at 30 mg/m2/d, each drug on days 1 to 3. Six cycles were to be given every 4 weeks. A total of 29 patients with relapsed or refractory indolent lymphoma were included in the study. During phase I, 9 patients were treated at dose level 1 and 7 patients at dose level 2. Thirteen patients were added to the study during phase II. Fourteen patients had follicular lymphoma, 11 patients mantle cell lymphoma, 2 patients lymphoplasmocytic and 2 patients nodal marginal zone lymphoma. Median age was 62 years (range 39-74). All patients were in stages III or IV of their disease and had received prior chemotherapy with or without additional radio- or immunotherapy. The dose limiting toxicity was hematotoxicity in all cases and occurred in 3 of 7 evaluable patients at dose level I and in 3 of 7 patients at dose level 2. One patient at dose level 2 died of sepsis in neutropenia with persistent thrombocytopenia. The study was continued at dose level 1 (phase II). Analysis of 19 evaluable patients treated at dose level 1 reveiled hematotoxicity CTC grade III in 47% and grade IV in 26%. Neutropenic fever occurred in 4 patients (21%). On an intent-to-treat basis, 45% or 32% of all patients at dose level 1 reached CR or PR, respectively. Nine of 9 patients with mantle cell lymphoma responded to therapy. The overall response rate was 77%. Eight of 15 responders relapsed after a median follow-up time of 14 months (range 2-43). The major complication of fludarabine in combination with bendamustine is hematotoxicity. Dose level 1 with 30 mg/m2/d of both drugs on days 1 to 3 was defined as the recommended dose. Despite unfavorable prognostic features (histologic subtype, stage of disease, pretreatment) response rates were good with this regimen.
