Prognostic and predictive factors for angiosarcoma patients receiving paclitaxel once weekly plus or minus bevacizumab: an ancillary study derived from a randomized clinical trial.

ABSTRACT: BACKGROUND:We report here a correlation analysis conducted along with a phase II trial assessing bevacizumab in combination with weekly paclitaxel. METHODS:Circulating pro/anti-angiogenic factors were assessed on day 1 (D1) and day 8 (D8). The prognostic value for progression-free survival (PFS) was evaluated using a Cox model with biomarkers as continuous variables. RESULTS:Among the 51 patients enrolled and treated in this trial, biomarker analysis was performed for 42: 18 in Arm A (single-agent) and 24 in Arm B (combination). With a median follow-up of 46 months, PFS was 5.5 versus 5.7 months, respectively (p?=?0.75). According to univariate analysis, factors associated with a poor PFS were as follows: visceral angiosarcoma, de novo angiosarcoma, and high PlGF and low VEGF-C baseline values. In multivariate analysis, de novo angiosarcoma (HR?=?2.5; p?=?0.024) and baseline VEGF-C value (HR?=?0.7; p?=?0.003) were significant prognostic factors. We observed a significant increase in circulating PlGF (

Project description:BackgroundStimulation of vascular endothelial growth factor (VEGF) has been observed following transarterial chemoembolization (TACE) in hepatocellular cancer (HCC) and may contribute to tumor regrowth. This pilot study examined whether intravenous (IV) bevacizumab, a monoclonal antibody against VEGF, could inhibit neovessel formation after TACE.Methods30 subjects with HCC undergoing TACE at a single academic institution were randomized with a computer-generated allocation in a one to one ratio to either bevacizumab at a dose of 10 mg/kg IV every 14 days beginning 1 week prior to TACE (TACE-BEV arm) or observation (TACE-O arm). Angiography was performed with TACE at day 8, and again at weeks 10 and 14. Repeat TACE was performed at week 14 if indicated. TACE-BEV subjects were allowed to continue bevacizumab beyond week 16. TACE-O subjects were allowed to cross-over to bevacizumab at week 16 in the setting of progressive disease. The main outcome measure was a comparison of neovessel formation by serial angiography. Secondary outcome measures were progression free survival (PFS) at 16 weeks, overall survival (OS), bevacizumab safety, and an analysis of VEGF levels before and after TACE with and without bevacizumab.ResultsAmong the 30 subjects enrolled, 9 of 15 randomized to the TACE-O arm and 14 of 15 randomized to the TACE-BEV arm completed all 3 angiograms. At week 14, 3 of 9 (33%) TACE-O subjects and 2 of 14 (14%) TACE-BEV subjects demonstrated neovascularity. The PFS at 16 weeks was 0.19 in the TACE-O arm and 0.79 in the TACE-BEV arm (p = 0.021). The median OS was 61 months in the TACE-O arm and 49 months in the TACE-BEV arm (p = 0.21). No life-threatening bevacizumab-related toxicities were observed. There were no substantial differences in bevacizumab pharmacokinetics compared to historical controls. Bevacizumab attenuated the increase in VEGF observed post-TACE.ConclusionsIV bevacizumab was well tolerated in selected HCC subjects undergoing TACE, and appeared to diminish neovessel formation at week 14.Trial registrationClinicalTrials.gov NCT00049322.

Project description:AIMS:Dapagliflozin and exenatide reduce body weight by differing mechanisms. Dual therapy with these agents reduces body weight, adipose tissue volume, glycaemia and systolic blood pressure (SBP) over 24?weeks. Here, we examined these effects over 1?year in obese adults without diabetes. MATERIALS AND METHODS:Obese adults without diabetes (N?=?50; aged 18-70?years; body mass index, 30-45?kg/m2 ) were initially randomized to double-blind oral dapagliflozin 10?mg once daily plus subcutaneous long-acting exenatide 2?mg once weekly or to placebo. They entered an open-label extension from 24 to 52?weeks during which all participants received active treatment. RESULTS:Of the original 25 dapagliflozin?+?exenatide-treated and 25 placebo-treated participants, respectively, 21 (84%) and 17 (68%) entered the open-label period and 16 (64%) and 17 (68%) completed 52?weeks of treatment. At baseline, mean body weight was 104.6?kg, and 73.5% of participants had prediabetes (impaired fasting glucose or impaired glucose tolerance). Reductions with dapagliflozin?+?exenatide at 24?weeks were sustained at 52?weeks, respectively, for body weight (-4.5 and -5.7?kg), total adipose tissue volume (-3.8 and -5.3?L), proportion with prediabetes (34.8% and 35.3%), and SBP (-9.8 and -12.0?mm Hg). Effects on body weight, SBP and glycaemia at 52?weeks with placebo???dapagliflozin?+?exenatide were similar to those observed with continuation of dapagliflozin?+?exenatide. Nausea and injection-site reactions were more frequent with dapagliflozin?+?exenatide than with placebo and diminished over time. Safety and tolerability were similar to that in previous diabetes trials with these agents. No clear difference in adverse event-related withdrawals between placebo and active treatment periods was observed. CONCLUSIONS:Dapagliflozin?+?exenatide dual therapy produced sustained reductions in body weight, prediabetes and SBP over 52?weeks and was well tolerated in obese adults without diabetes.
