    Measuring salivary cortisol is a simple, convenient and accurate technique with potential value in monitoring patients with hypercortisolism. This analysis reports changes in late-night salivary cortisol (LNSC) during a 12-month, multicentre, Phase III study of patients with Cushing’s disease who were randomized to pasireotide 600 or 900 lg sc bid. LNSC assessment was an exploratory objective based on a single, optional measurement at midnight ± 1 h on the same day as one of the 24-h urinary free cortisol (UFC) measurements. Of 162 enrolled patients, baseline LNSC was measured in 93. Sixty-seven patients had levels above the upper limit of normal (ULN); median baseline levels were 19.7 and 20.7 nmol/L in the groups subsequently randomized to 600 lg (n = 40) and 900 lg (n = 27), respectively. Median LNSC levels decreased from baseline to month 12; median changes in patients who had baseline LNSC [ULN in the 600 and 900 lg groups were -13.4 nmol/L (–52.6 %; n = 19) and -11.8 nmol/L (–56.1 %; n = 14), respectively. LNSC normalized at months 6 and 12 in 25/67 (37.3 %) and 13/67 (19.4 %) patients, respectively; 10/25 and 8/13 patients also had normalized UFC, and 7/25 and 4/13 had partial UFC control (UFC [ULN and C50 % decrease from baseline). There was a moderate correlation (r = 0.55) on the log scale between individual patient LNSC and UFC values when all time points were pooled. Pasireotide decreased LNSC levels during 12 months of treatment. Salivary cortisol may be a simple, convenient biomarker for assessing treatment response in patients with Cushing’s disease

    Long-term outcomes of osilodrostat in Cushing’s disease: LINC 3 study extension

    Objective To investigate the long-term efficacy and tolerability of osilodrostat, a potent oral 11β-hydroxylase inhibitor, for treating Cushing’s disease (CD). Design/methods A total of 137 adults with CD and mean 24-h urinary free cortisol (mUFC) > 1.5 × upper limit of normal (ULN) received osilodrostat (starting dose 2 mg bid; maximum 30 mg bid) during the prospective, Phase III, 48-week LINC 3 (NCT02180217) core study. Patients benefiting from osilodrostat at week 48 could enter the optional extension (ending when all patients had received ≥ 72 weeks of treatment or discontinued). Efficacy and safety were assessed for all enrolled patients from the core study baseline. Results Median osilodrostat exposure from the core study baseline to study end was 130 weeks (range 1–245) and median average dose was 7.4 mg/day (range 0.8–46.6). The reduction in mean mUFC achieved during the core was maintained during the extension and remained ≤ ULN. Of 106 patients, 86 (81%) patients who entered the extension had mUFC ≤ ULN at week 72. Improvements in cardiovascular/metabolic-related parameters, physical manifestations of hypercortisolism (fat pads, central obesity, rubor, striae, and hirsutism in females), and quality of life in the core study were also maintained or improved further during the extension. No new safety signals were reported; 15/137 (10.9%) and 12/106 (11.3%) patients discontinued for adverse events during the core and extension, respectively. Mean testosterone in females decreased towards baseline levels during the extension. Conclusions Data from this large, multicentre trial show that long-term treatment with osilodrostat sustains cortisol normalisation alongside clinical benefits in most patients with CD and is well tolerated

    Risk factors and management of pasireotide-associated hyperglycemia in acromegaly

    Pasireotide, a multireceptor-targeted somatostatin analog with highest affinity for somatostatin receptor subtype (SST) 5, has demonstrated superior efficacy over the SST2-preferential somatostatin analogs octreotide and lanreotide. The safety profile is similar to those of octreotide and lanreotide, except for a higher frequency and degree of hyperglycemia. This analysis investigated baseline characteristics and occurrence and management of hyperglycemia during pasireotide treatment in patients with acromegaly treated in two prospective clinical studies, SOM230C2305 (C2305) and SOM230C2402 (C2402; PAOLA)

    A Quantized Consensus Algorithm for a Multi-Agent Assignment Problem

    No full text
    This paper proposes a novel distributed algorithm for a multi-agent assignment problem, in which a group of agents has to reach a consensus on an optimal distribution of tasks among themselves. Distributing a number of tasks to a number of agents is one of the most fundamental resource allocation problems that appear in numerous control and decision systems, ranging from multi-agent robotics to processor allocation in computing systems. The problem is formalized as a distributed consensus algorithm, i.e., as a procedure using which the agents can exchange messages and update autonomously and iteratively their assigned tasks. The proposed distributed algorithm aims to minimize the task costs assuming that each agent can perform a subset of the available tasks and can communicate with a subset of agents. Some results prove that the convergence to a task assignment consensus is reached and a suitable stopping criterion is given

    Assignment of electrical vehicles to charging stations by a distributed approach

    No full text
    This paper presents a solution for the distributed dynamic assignment of a set of electric vehicles to a network of charging stations. The drivers of the vehicles send requests for the charging of their own vehicle; then they receive the location of the station to reach for the battery charging. The problem is solved using some distributed multi-agent assignment algorithms: the stations reach a consensus solving some local integer linear programming problems. Moreover, the convergence of the algorithms is proved and an example shows the efficiency of the proposed solution. \ua9 2014 EUCA
