RESUMO
BACKGROUND: Allergic rhinoconjunctivitis (ARC) due to birch pollen is a growing health concern in Europe. Here, we report the efficacy and safety of 300IR birch pollen sublingual solution administered discontinuously for 2 consecutive years to patients with birch-associated allergic rhinoconjunctivitis. METHODS: Birch pollen-allergic adults were randomized in this double blind study to 300IR birch pollen sublingual solution or placebo, daily, starting 4 months before and continuing through the pollen season for two pollen seasons. Randomization was stratified according to the presence or absence of oral allergy syndrome (OAS). The primary efficacy endpoint was the Average Adjusted Symptom Score (AAdSS) over the second pollen season and was analyzed by ANCOVA. Secondary efficacy endpoints included the AAdSS over the first pollen period. Safety was evaluated by means of adverse event monitoring. RESULTS: 574 patients (284 in the active group and 290 in the placebo group) were randomized and 496 completed the study. Over the second pollen period, the least square (LS) mean AAdSS was significantly lower in the 300IR group than in the placebo group (LS mean difference -2.04, 95% CI [-2.69, -1.40], (p <0.0001) with a relative reduction of 30.6%. Results were consistent in patients with and without OAS (-33.6% and -28.4%, respectively). A significant reduction in LS mean AAdSS was also observed over the first pollen season. The most frequently reported adverse events were application site reactions: oral pruritus, throat irritation, and mouth edema. There were no reports of anaphylaxis. CONCLUSIONS: Pre- and co-seasonal treatment with 300IR birch pollen sublingual solution demonstrated sustained clinical efficacy over 2 pollen seasons and was well tolerated in adults with birch pollen-associated allergic rhinoconjunctivitis. Efficacy results were consistent in patients with and without oral allergy syndrome. TRIAL REGISTRATION: ClinicalTrials.gov: NCT01731249.
RESUMO
PURPOSE: Malignant pleural mesothelioma (MPM) is a disease of increasing incidence for which treatment options are limited. This study reports the clinical efficacy data for vinflunine, a novel microtubule inhibitor, in MPM. PATIENTS AND METHODS: Patients with a histologically confirmed diagnosis of MPM were eligible for enrollment onto this multicenter phase II trial if they had not received prior chemotherapy or radiotherapy and had measurable lesions by Response Evaluation Criteria in Solid Tumors (RECIST) criteria. Vinflunine 320 mg/m2 by 10-minute intravenous infusion was administered on day 1 of 21-day cycles. Modifications of dose and schedule were made according to National Cancer Institute Common Toxicity Criteria version 2.0. Efficacy was assessed by an external, independent radiologist. The one-sample multiple testing procedure of Fleming was applied at the predetermined recruitment stages of 20 and 40 assessable patients. RESULTS: Sixty-seven patients were enrolled. Five patients were not assessable for tumor response. The response rate was 13.8% (95% CI, 6.5% to 24.7%). The median survival was 10.8 months (95% CI, 7.8 to 12.0 months). The most common adverse events were anemia, neutropenia, fatigue, constipation, and nausea. Of grade 3 and 4 toxicities, neutropenia and constipation were the most common (45% and 9% of patients, respectively). CONCLUSION: Vinflunine can be delivered with high-dose intensity in patients with MPM. The response rate and median survival are encouraging for a single agent. These data suggest that vinflunine should be further evaluated in the management of MPM.
