Fulvestrant 500 mg versus anastrozole 1 mg for hormone receptor-positive advanced breast cancer (FALCON): an international, randomised, double-blind, phase 3 trial

Background Aromatase inhibitors are a standard of care for hormone receptor-positive locally advanced or metastatic breast cancer. We investigated whether the selective oestrogen receptor degrader fulvestrant could improve progression-free survival compared with anastrozole in postmenopausal patients who had not received previous endocrine therapy. Methods In this phase 3, randomised, double-blind trial, we recruited eligible patients with histologically confirmed oestrogen receptor-positive or progesterone receptor-positive, or both, locally advanced or metastatic breast cancer from 113 academic hospitals and community centres in 20 countries. Eligible patients were endocrine therapy-naive, with WHO performance status 0–2, and at least one measurable or non-measurable lesion. Patients were randomly assigned (1:1) to fulvestrant (500 mg intramuscular injection; on days 0, 14, 28, then every 28 days thereafter) or anastrozole (1 mg orally daily) using a computer-generated randomisation scheme. The primary endpoint was progression-free survival, determined by Response Evaluation Criteria in Solid Tumors version 1·1, intervention by surgery or radiotherapy because of disease deterioration, or death from any cause, assessed in the intention-to-treat population. Safety outcomes were assessed in all patients who received at least one dose of randomised treatment (including placebo). This trial is registered with ClinicalTrials.gov, number NCT01602380. Findings Between Oct 17, 2012, and July 11, 2014, 524 patients were enrolled to this study. Of these, 462 patients were randomised (230 to receive fulvestrant and 232 to receive anastrozole). Progression-free survival was significantly longer in the fulvestrant group than in the anastrozole group (hazard ratio [HR] 0·797, 95% CI 0·637–0·999, p=0·0486). Median progression-free survival was 16·6 months (95% CI 13·83–20·99) in the fulvestrant group versus 13·8 months (11·99–16·59) in the anastrozole group. The most common adverse events were arthralgia (38 [17%] in the fulvestrant group vs 24 [10%] in the anastrozole group) and hot flushes (26 [11%] in the fulvestrant group vs 24 [10%] in the anastrozole group). 16 (7%) of 228 patients in in the fulvestrant group and 11 (5%) of 232 patients in the anastrozole group discontinued because of adverse events. Interpretation Fulvestrant has superior efficacy and is a preferred treatment option for patients with hormone receptor-positive locally advanced or metastatic breast cancer who have not received previous endocrine therapy compared with a third-generation aromatase inhibitor, a standard of care for first-line treatment of these patients

FALCON: A phase III randomised trial of fulvestrant 500 mg vs. anastrozole for hormone receptor-positive advanced breast cancer

Background: This Phase III, randomised, double-blind, multicentre trial (FALCON; NCT01602380) compared the selective estrogen receptor (ER) degrader (SERD) fulvestrant with anastrozole in patients with ER- and/or progesterone receptor-positive locally advanced or metastatic breast cancer who had not received prior hormonal therapy. Methods: Patients were randomised 1:1 to fulvestrant (500 mg IM on Days 0, 14, 28, then each 28 days) or anastrozole (1 mg daily). The primary endpoint was progression-free survival (PFS), assessed via RECIST 1.1, surgery/radiotherapy for disease worsening, or death. Secondary endpoints were: overall survival (OS); objective response rate (ORR, complete response [CR] or partial response [PR]); duration of response (DoR); expected DoR (EDoR); clinical benefit rate (CBR; CR, PR, or stable disease ≥24 weeks); duration of clinical benefit (DoCB); expected DoCB (EDoCB); health-related quality of life (HRQoL); and safety

BEECH: a dose-finding run-in followed by a randomised phase II study assessing the efficacy of AKT inhibitor capivasertib (AZD5363) combined with paclitaxel in patients with estrogen receptor-positive advanced or metastatic breast cancer, and in a PIK3CA mutant sub-population.

Background BEECH investigated the efficacy of capivasertib (AZD5363), an oral inhibitor of AKT isoforms 1-3, in combination with the first-line weekly paclitaxel for advanced or metastatic estrogen receptor-positive (ER+)/human epidermal growth factor receptor 2-negative (HER2-) breast cancer, and in a phosphoinositide 3-kinase, catalytic, alpha polypeptide mutation sub-population (PIK3CA+).Patients and methods BEECH consisted of an open-label, phase Ib safety run-in (part A) in 38 patients with advanced breast cancer, and a randomised, placebo-controlled, double-blind, phase II expansion (part B) in 110 women with ER+/HER2- metastatic breast cancer. In part A, patients received paclitaxel 90 mg/m2 (days 1, 8 and 15 of a 28-day cycle) with capivasertib taken twice daily (b.i.d.) at two intermittent ascending dosing schedules. In part B, patients were randomly assigned, stratified by PIK3CA mutation status, to receive paclitaxel with either capivasertib or placebo. The primary end point for part A was safety to recommend a dose and schedule for part B; primary end points for part B were progression-free survival (PFS) in the overall and PIK3CA+ sub-population.Results Capivasertib was well tolerated, with a 400 mg b.i.d. 4 days on/3 days off treatment schedule selected in part A. In part B, median PFS in the overall population was 10.9 months with capivasertib versus 8.4 months with placebo [hazard ratio (HR) 0.80; P = 0.308]. In the PIK3CA+ sub-population, median PFS was 10.9 months with capivasertib versus 10.8 months with placebo (HR 1.11; P = 0.760). Based on the Common Terminology Criteria for Adverse Event v4.0, the most common grade ≥3 adverse events in the capivasertib group were diarrhoea, hyperglycaemia, neutropoenia and maculopapular rash. Dose intensity of paclitaxel was similar in both groups.Conclusions Capivasertib had no apparent impact on the tolerability and dose intensity of paclitaxel. Adding capivasertib to weekly paclitaxel did not prolong PFS in the overall population or PIK3CA+ sub-population of ER+/HER2- advanced/metastatic breast cancer patients.ClinicalTrials.gov: NCT01625286

An investigation of leadership styles and relationship cultures of Chinese and expatriate managers in multinational construction companies in Hong Kong

Cross-cultural leadership research has predicted that the Chinese are perceived as people-oriented and prefer a high-context power relationship, whereas Westerners are perceived as task-oriented and prefer a low-context power relationship. However, such general predictions are less accurate when intercultural interactions exist in multicultural workplaces. For this reason leadership perceptions and power relationships of both Chinese and Western expatriate project managers are explored in multinational construction firms in Hong Kong. Questionnaire data from 45 project managers and 61 subordinates suggested that the local (Hong Kong) Chinese and Western expatriate managers do not differ significantly in terms of leadership perceptions and power relationships. Both manager groups equally considered the importance of task performance and interpersonal relationships. Two possibilities are proposed which lead to similar leadership and power relationship styles of managers from different cultural orientations: the 'intercultural adjustment' of expatriates, and the adaptation of Western styles of leadership by the Hong Kong Chinese project managers.China, project manager, leadership, culture, international business,

Phase II study to assess the efficacy, safety and tolerability of the mitotic spindle kinesin inhibitor AZD4877 in patients with recurrent advanced urothelial cancer

Background AZD4877 is a potent inhibitor of the mitotic spindle kinesin, Eg5. Early-phase clinical studies in a broad range of cancers showed that AZD4877 is well tolerated. This Phase II study evaluated the efficacy, safety and pharmacokinetics (Cmax) of AZD4877 in patients with previously treated advanced urothelial cancer (ClinicalTrials.gov identifier NCT00661609). Patients and methods AZD4877 25 mg was administered once-weekly for 3 weeks of each 4-week cycle until disease progression, death, unacceptable toxicity or withdrawal. The primary objective was to determine the objective response rate (RECIST). Recruitment was to be halted if ≤2 of the first 20 evaluable patients achieved an objective tumor response. Cmax was assessed on days 1 and 8 of cycle 1. Results None of the first 20 patients evaluable for efficacy achieved an objective response; enrollment was therefore halted. During this initial analysis, a further 21 patients were recruited. Overall, 39 patients were evaluable for efficacy, including one with confirmed partial response (PR) and seven patients with stable disease for ≥8 weeks (including one unconfirmed PR). The most commonly reported treatment-related adverse events (TRAEs) were neutropenia (22 patients), fatigue (12), leukopenia (7) and constipation (6); the most commonly reported grade ≥3 TRAE was neutropenia (21). Four patients had serious TRAEs. On days 1 and 8, the geometric mean Cmax of AZD4877 was 138 ng/ml (CV = 75 %) and 144 ng/ml (CV = 109 %), respectively. Conclusions AZD4877 was generally tolerable in patients with advanced urothelial cancer. Given the limited clinical efficacy, further development of AZD4877 in urothelial cancer is not planned

Coenzyme Q10 in Metabolic syndrome

Metabolic syndrome (MS) has become a global health issue due to affect a high percentage of people in most of the countries. MS can be defined as the presence of three of the following factors: obesity, high triglyceride and cholesterol levels, low HDL cholesterol, high blood pressure or high fasting plasma glucose. All these factors increase the risk of cardiovascular disease, diabetes type II, some kind of cancers, sleep abnormalities or physical incapacity among other. Several factors have been identified in the aetiology of MS such as dietary patterns, sedentary lifestyle, genetic background, microbiota, socioeconomic status or age. Different treatments have been proposed for the treatment of MS, but, until today, there is no efficient solution. CoQ10 has emerged as a potential way in MS treatment endorsed by several clinical trials have shown improvements in lipid profile, glucose control, insulin homeostasis and hypertension control in MS patients. The molecular mechanism that could explain these improvements would be the antioxidant capacity of CoQ10 inhibiting oxidative stress that it is present in MS. Additionally, the proportion of CoQ10H2 could be also a crucial role in the protection again MS components. Furthermore, CoQ10 administration could be also helpful in the management of mitochondrial dysfunction associated to MS
