In randomized clinical trials, the androgen-receptor inhibitor enzalutamide has demonstrated efficacy and safety in metastatic castration-resistant prostate cancer (mCRPC). This study captured efficacy, safety and patient-reported outcomes (PROs) of enzalutamide in mCRPC patients in a real-world European setting. PREMISE (NCT0249574) was a European, long-term, prospective, observational study in mCRPC patients prescribed enzalutamide as part of standard clinical practice.

Methods: A post-hoc analysis of the Japanese subgroup in the phase III, randomized, multinational ARCHES study (NCT02677896) was carried out. Patients with metastatic hormone-sensitive prostate cancer were randomized to receive enzalutamide or a placebo, plus androgen deprivation therapy, stratified by disease volume and prior docetaxel therapy.
Purpose: Enzalutamide, a potent androgen-receptor inhibitor, has demonstrated significant benefits in metastatic and nonmetastatic castration-resistant prostate cancer. We evaluated the efficacy and safety of enzalutamide in metastatic hormone-sensitive prostate cancer (mHSPC).
Methods: ARCHES (ClinicalTrials.
Purpose: A phase 2 study of enzalutamide monotherapy in patients with hormone naïve prostate cancer demonstrated high prostate specific antigen response rates at 25 weeks, 1 year and 2 years with minimal effects on total body bone mineral density and favorable safety. In this followup analysis we evaluated enzalutamide antitumor activity and safety at 3 years.
Materials And Methods: In a single arm analysis 67 patients with hormone naïve prostate cancer and noncastrate testosterone (230 ng/dl or greater) received enzalutamide 160 mg per day orally until disease progression or unacceptable toxicity.
Background: Enzalutamide and abiraterone acetate plus prednisone, which target the androgen receptor axis, have expanded the treatment of advanced prostate cancer. Retrospective analyses suggest some cross-resistance between these two drugs when used sequentially, but robust, prospective studies have not yet been reported.
Objective: To fulfil a regulatory postregistration commitment by evaluating the efficacy and safety of enzalutamide in patients with metastatic castration-resistant prostate cancer (mCRPC) who progressed following abiraterone acetate plus prednisone treatment.
Purpose: Enzalutamide significantly prolonged median progression-free survival vs bicalutamide in chemotherapy naïve men with metastatic castration resistant prostate cancer in the TERRAIN (Enzalutamide versus Bicalutamide in Castrate Men with Metastatic Prostate Cancer) trial. In this post hoc analysis we investigated the influence of age on the efficacy and safety of enzalutamide vs bicalutamide in this population.
Materials And Methods: Patients were randomized 1:1 to enzalutamide 160 mg per day or bicalutamide 50 mg per day.
Background: Improving health-related quality of life (HRQoL) is an important goal in metastatic castration-resistant prostate cancer (mCRPC).
Objective: To examine the impact of enzalutamide versus bicalutamide on HRQoL in mCRPC.
Design, Setting, And Participants: TERRAIN is a multinational, phase 2, randomised, double-blind study in asymptomatic/mildly symptomatic men with mCRPC (ClinicalTrials.
Background: Enzalutamide is an androgen receptor inhibitor with a demonstrated overall survival benefit in metastatic castration-resistant prostate cancer. A phase 2 study of enzalutamide monotherapy in patients with hormone-naïve prostate cancer (HNPC) showed a high response rate for the prespecified primary endpoint (ie, prostate-specific antigen [PSA] response at week 25), regardless of metastases at baseline, and favorable tolerability.
Objective: To determine the long-term efficacy and safety of enzalutamide monotherapy at 1 and 2 yr.
Background: ASP9521 is a first-in-class orally available inhibitor of the enzyme 17 β-hydroxysteroid dehydrogenase type 5 (17 βHSD5; AKR1C3), catalysing the conversion of dehydroepiandrosterone and androstenedione into 5-androstenediol and testosterone. It has demonstrated anti-tumour activity in in vitro and in vivo preclinical models.
Material And Methods: This first-in-man phase I/II study utilised a 3 + 3 dose escalation design starting at 30 mg ASP9521/day, with the aim of defining a maximum tolerated dose, as defined by the incidence of dose-limiting toxicities.
Studies in animals synchronized with an alternation of 12 h of light and 12 h of darkness have showed that hematological and systemic toxicities could be reduced if vinorelbine were administered 19 or 23 hours after light onset (HALO), corresponding to 17:00 and 21:00 h in diurnally active humans. This trial aimed to define the least toxic time of vinorelbine administration in metastatic breast cancer patients. Initially, the study treatment consisted of three courses of vinorelbine of 30 mg/m(2)/d on D1 and D6 and chronomodulated 5-fluorouracil of 850 mg/m(2) from D2 to D5 every 21 days.

As a result, both the toxicity and efficacy of over 30 anticancer agents vary by more than 50% as a function of dosing time in experimental models. The circadian timing system also down-regulates malignant growth in experimental models and possibly in cancer patients.

Patients And Methods: For this multicenter randomized trial, it was hypothesized that a chronomodulated infusion of fluorouracil, leucovorin, and oxaliplatin for 4 days (chronoFLO4) would improve survival by 10% compared with conventional 2-day delivery of the same drugs (FOLFOX2). Patients were treated every 2 weeks with intrapatient dose escalation.
Many clinicians often do not feel comfortable with the Continual Reassessment Method (CRM). This article reviews its implementation, showing the characteristics, advantages and limitations of this method in Phase I studies as an alternative to the classical 'Fibonacci' escalation schema. A two center, dose escalation phase I study of rViscumin was carried out.

Retrospectively, we determined whether the use of this CA-125 definition in a randomized trial would have shown the same magnitude of difference between the treatment arms as was shown when the standard progression definition was used.
Patients And Methods: A retrospective analysis was performed on 680 patients in the Taxol Intergroup Trial with advanced epithelial ovarian carcinoma, of whom 628 were assessable according to CA-125.
Purpose: Incapacitating symptom burden in cancer patients contributes to poor quality of life (QOL) and can influence treatment outcomes because of poor tolerance to therapy. In this study, the role of circulating cytokines in the production symptoms in cancer patients is evaluated.
Experimental Design: Eighty patients with metastatic colorectal cancer with either normal (group I, n = 40) or dampened (group II, n = 40) 24-hour rest/activity patterns measured by actigraphy were identified.
Objective: To assess the economic impact of two polychemotherapy regimens for patients with advanced ovarian cancer from the perspective of the Belgian health insurance and financing system.
Design: An economic evaluation was integrated in an intergroup randomised controlled trial (EORTC 55931) in which patients were randomised to receive the new treatment of paclitaxel and cisplatin or the standard therapy of cyclophosphamide and cisplatin. Data on the use of medical resources were collected prospectively for the 231 European Organization for Research and Treatment of Cancer (EORTC) patients in the trial and costs were valued by using unit prices.
