Background: Patients with metastatic bone disease are living longer in the metastatic stage due to improvements in cancer therapy, making strategies to prevent the aggravation of bone disease and its complications, such as skeletal-related events (SREs) and pain, increasingly important. Patients and results: In this phase 3 trial in patients with advanced cancer (excluding breast and prostate cancer) or multiple myeloma, denosumab reduced the risk of radiation to bone by 22% relative to zoledronic acid (P = 0.026), prevented worsening of pain and pain interference (2-point increase in Brief Pain Inventory score; P < 0.05 versus zoledronic acid), and reduced the frequency of a shift from no/weak opioid analgesic use to strong opioids (P < 0.05 versus zoledronic acid at months 3-5). Denosumab delayed the time to moderate-to-severe pain compared with zoledronic acid in patients with mild or no pain at the baseline (P = 0.04), supporting early treatment. Health-related quality-of-life scores were similar in both groups. The number needed to treat to avoid one SRE for denosumab was 3 patient-years versus placebo and 10 patient-years versus zoledronic acid. Conclusion: The use of denosumab was associated with better prevention of the complications of metastatic bone disease secondary to solid tumors or multiple myeloma versus zoledronic acid. © The Author 2012.

Objective: With increasing healthcare resource constraints, it has become important to understand the incremental cost-effectiveness of new medicines. Subcutaneous denosumab is superior to intravenous zoledronic acid (ZA) for the prevention of skeletal-related events (SREs) in patients with advanced solid tumors and bone metastases. This study sought to determine the lifetime cost-effectiveness of denosumab vs ZA in this setting, from a US managed-care perspective. Methods: A lifetime Markov model was developed, with relative rate reductions in SREs for denosumab vs ZA derived from three pivotal Phase 3 trials involving patients with castration-resistant prostate cancer (CRPC), breast cancer, and non-small-cell lung cancer (NSCLC), and bone metastases. The real-world SRE rates in ZA-treated patients were derived from a large commercial database. SRE and treatment administration quality-adjusted life year (QALY) decrements were estimated with time-trade-off studies. SRE costs were estimated from a nationally representative commercial claims database. Drug, drug administration, and renal monitoring costs were included. Costs and QALYs were discounted at 3 annually. One-way and probabilistic sensitivity analyses were conducted. Results: Across tumor types, denosumab was associated with a reduced number of SREs, increased QALYs, and increased lifetime total costs vs ZA. The costs per QALY gained for denosumab vs ZA in CRPC, breast cancer, and NSCLC were $49,405, $78,915, and $67,931, respectively, commonly considered good value in the US. Costs per SRE avoided were $8567, $13,557, and $10,513, respectively. Results were sensitive to drug costs and SRE rates. Limitations: Differences in pain severity and analgesic use favoring denosumab over ZA were not captured. Mortality was extrapolated from fitted generalized gamma function beyond the trial duration. Conclusion: Denosumab is a cost-effective treatment option for the prevention of SREs in patients with advanced solid tumors and bone metastases compared to ZA. The overall value of denosumab is based on superior efficacy, favorable safety, and more efficient administration. © 2012 Informa UK Ltd All rights reserved. Source

This randomised phase III trial evaluated first-line trabectedin versus doxorubicin-based chemotherapy (DXCT) in patients with advanced/metastatic translocation-related sarcomas (TRS). Methods Patients were randomly assigned (1:1) to receive trabectedin 1.5 mg/m2 24-h intravenous (i.v.) infusion every 3 weeks (q3wk) (Arm A), or doxorubicin 75 mg/m2 i.v. q3wk, or doxorubicin 60 mg/m2 i.v. plus ifosfamide (range, 6-9 g/m2) i.v. q3wk (Arm B). Progression-free survival (PFS) by independent review was the primary efficacy end-point. Results One hundred and twenty-one patients were randomised; 88 of them had TRS confirmed by central pathology review (efficacy population). Twenty-nine PFS events were assessed by independent review (16 with trabectedin; 13 with DXCT). PFS showed non-significant difference between arms (stratified log rank test, p = 0.9573; hazard ratio = 0.86, p = 0.6992). At the time of this analysis, 63.9% and 58.3% of patients were alive in trabectedin and DXCT arms, respectively. There was no statistically significant difference in survival curves. Response rate according to Response Evaluation Criteria in Solid Tumours (RECIST) v.1.0 was significantly higher in DXCT arm (27.0% versus 5.9%), but response according to Choi criteria showed fewer differences between treatment arms (45.9% versus 37.3%). Safety profile was as expected for both arms, with higher incidence of severe neutropenia, alopecia and mucositis in the DXCT arm. Conclusion Neither trabectedin nor doxorubicin-based chemotherapy showed significant superiority in the first-line treatment of patients with advanced translocation-related sarcoma. © 2014 Elsevier Ltd.

INTRODUCTION:: Denosumab, a fully human anti-RANKL monoclonal antibody, reduces the incidence of skeletal-related events in patients with bone metastases from solid tumors. We present survival data for the subset of patients with lung cancer, participating in the phase 3 trial of denosumab versus zoledronic acid (ZA) in the treatment of bone metastases from solid tumors (except breast or prostate) or multiple myeloma. METHODS:: Patients were randomized 1:1 to receive monthly subcutaneous denosumab 120 mg or intravenous ZA 4 mg. An exploratory analysis, using Kaplan-Meier estimates and proportional hazards models, was performed for overall survival among patients with non-small-cell lung cancer (NSCLC) and SCLC. RESULTS:: Denosumab was associated with improved median overall survival versus ZA in 811 patients with any lung cancer (8.9 versus 7.7 months; hazard ratio [HR] 0.80) and in 702 patients with NSCLC (9.5 versus 8.0 months; HR 0.78) (p = 0.01, each comparison). Further analysis of NSCLC by histological type showed a median survival of 8.6 months for denosumab versus 6.4 months for ZA in patients with squamous cell carcinoma (HR 0.68; p = 0.035). Incidence of overall adverse events was balanced between treatment groups; serious adverse events occurred in 66.0% of denosumab-treated patients and 72.9% of ZA-treated patients. Cumulative incidence of osteonecrosis of the jaw was similar between groups (0.7% denosumab versus 0.8% ZA). Hypocalcemia rates were 8.6% with denosumab and 3.8% with ZA. CONCLUSION:: In this exploratory analysis, denosumab was associated with improved overall survival compared with ZA, in patients with metastatic lung cancer. © 2012 by the International Association for the Study of Lung Cancer.

Purpose: In July 2007, the Centers for Medicare andMedicaid Services (CMS) limited coverage of erythropoiesisstimulating agents (ESAs) in cancer patients with chemotherapy-induced anemia (CIA) through a National Coverage Determination (NCD). The primary objective of this study was to compare transfusion rates in patients with CIAwith lung, breast, or colorectal cancer before and after the NCD. Methods: Adult Medicare patients with CIA treated at 49 community oncology clinics were selected from two time periods based on clinics' NCD implementation date. Chart data were abstracted for 12 weeks post-CIA episode start, defined as hemoglobin (Hb) level <11 g/dL while receiving chemotherapy or within 60 days of the last chemotherapy dose. Multivariate analyses were used to calculate the odds of transfusion and to assess the units of blood transfused, controlling for differences in demographics, clinical history, and chemotherapy. Results: Eight hundred pre-NCD and 994 post-NCD patients from 49 sites were selected. Of the patients, 56% used ESAs post-NCD vs. 88% pre-NCD (p<0.0001). The duration of ESA use decreased in the post-NCD (32.1 days) vs. pre-NCD (48.4 days, p<0.0001) group. The post-NCD group reported significantly lower Hb levels, higher odds of receiving a transfusion (odds ratio: 1.41, 95% CI 1.05-1.89, p=0.0238) and inc:reased blood utilization of 53% (units transfused: OR 1.53, 95% CI 1.15-2.04, p=0.0034). Conclusions: Decreased frequency and duration of ESA administration were reported in the post-NCD vs. pre-NCD period. Findings were accompanied by a modest but statistically significant increase in transfusions and a decrease in Hb values. © Springer-Verlag 2011. Source
