Introduction IMC-001 is a fully human IgG1 monoclonal antibody that binds to human PD-L1 (programmed death-ligand 1). This study evaluated the safety, pharmacokinetics, and pharmacodynamics of IMC-001 in patients with advanced solid tumors. Materials and Methods This open-labeled phase I study used a standard 3 + 3 dose-escalation design, with doses ranging from 2 to 20 mg/kg. IMC-001 was administered intravenously every 2 weeks until disease progression or unacceptable toxicity. The dose-limiting toxicity window was defined as 21 days from the first dose. see more Results Fifteen subjects were included in 5 dose-escalation cohorts. No dose-limiting toxicity was observed, and the maximum tolerated dose was not reached. The most common adverse events (AEs) were general weakness, decreased appetite, fever, and cough. No grade 4 or 5 treatment emergent AEs were reported during the study. One subject in the 2 mg/kg cohort showed grade 2 immune-induced thyroiditis and diabetes mellitus suspected to be related to IMC-001. Over the dose range of 2-20 mg/kg IMC-001, the AUC0-14d, AUC0-∞, and Cmax generally increased in a dose-proportional manner for each step of dose escalation. Of the 15 enrolled patients, 1 subject with rectal cancer showed a partial response, and the disease control rate was 33.3%. Conclusions IMC-001 demonstrated a favorable safety profile up to 20 mg/kg administered intravenously every 2 weeks and showed preliminary efficacy in patients with advanced solid tumors. Based on pharmacokinetic and pharmacodynamic data, 20 mg/kg was selected as the recommended phase II dose. Clinical trial identification NCT03644056 (date of registration August 23, 2018).In the last two decades, simultaneous global development of novel drugs become more common by conducting multiregional clinical trials. However, regulatory authorities of different regions often make different decisions on the approvals of the same new drugs. We would like to discuss the appropriateness of Japanese regulatory approach through a case study of quizartinib, a novel anti-leukemia drug developed in Japan. The pivotal clinical trial "QuANTUM-R" conducted in 19 countries showed a modest increase in median overall survival with quizartinib than the conventional chemotherapy. However, because several critical defects in this trial were pointed out by the United States Food and Drug Administration (US FDA) and the European Medicines Agency (EMA), quizartinib has not been approved in the US and Europe to date. On the contrary, the regulatory authority of Japan gave a notice of approval to quizartinib as a "standard of care", and the country becomes the sole country that granted market authorization. In our paper, we provide more detailed discussion about the methodology for scientific evaluation of the new drug.
Patients with atopic dermatitis (AD) experience burdensome symptoms and impaired quality of life (QoL). The objective of this study was to investigate the effects of topical AD therapies on disease control, physician and patient treatment satisfaction, and QoL in a real-world setting.
This was a retrospective, point-in-time study of physician-completed medical records and patient surveys drawn from two Adelphi AD Disease Specific Programmes™ (1. adults ≥ 18years old; 2. pediatrics ≤ 17years old) in the USA. Eligible physicians completed patient record forms and provided disease control assessments. Physicians and matched patients were surveyed regarding their satisfaction with current treatment. Patient-reported outcomes included the Dermatology Life Quality Index (DLQI), Children's DLQI (CDLQI), Patient-Oriented Eczema Measure (POEM), and the Work Productivity and Activity Impairment (WPAI) questionnaire.
A total of 394 adult (topicals only, n = 284; topical plus systemic, n = 110) and 144 adolescent (and reported decreased overall functioning and lower QoL. An unmet need for topical AD treatments that improve disease control and patient outcomes exists.
Patients receiving topical AD therapies experienced uncontrolled disease and reported decreased overall functioning and lower QoL. An unmet need for topical AD treatments that improve disease control and patient outcomes exists.
Due to the complex nature and high heterogeneity of motivational interviewing (MI) trials, available data on the effectiveness of these interventions on weight management in the early years of life is not yet conclusive. This study aimed to (1) evaluate the effectiveness of MI-based interventions on modifying obesity-related behaviors and consequently controlling weight in adolescents, and (2) determine characteristics of participants and interventions through sub-group analysis.
Electronic databases, i.e., Medline, Elsevier, ISI, Cochrane Central Register of Controlled Trials (Clinical Trials), PsycINFO, and subject-related key journals were searched for randomized controlled trials that investigated the effect of MI-based interventions on weight management in overweight/obese adolescents. Primary outcomes were BMI, BMI Z-score, waist circumference, and fat percentage. Secondary outcomes were related behaviors (dietary intake and physical activity) and cognitive abilities (self-efficacy, self-regulation, are the age of participants, MI fidelity assessment, parental involvement, duration of interventions, and type of the control groups.
The infertility experience is often surrounded by frustration and discouragement associated with the thwarted goal to have a child. Though research has identified commonly used strategies to cope with infertility, this study is the first to examine how different goal attributes and processes associated with the experience of infertility relate to coping strategy use and psychological distress.
Women (N = 353) recruited from online support forums reported on the nature of their goal to have a child, their psychological distress, and their use of strategies to cope with the failure to achieve that goal.
Women reported high striving toward a goal high in importance and commitment, coupled with high goal-related stress and feeling that achievement is blocked. Consistent with the notion that coping strategy use is specific to the features of the experience, no single goal attribute nor combination of attributes consistently accounted for coping strategy use, suggesting that the latter may be specific to the cognitions and processes of pursuit of the goal to have a child.
