Two issues on clinical trials with multiple endpoints were surveyed (1) the terminology of multiple endpoints, relationship between rare events and endpoints, and differences in multiplicity adjustment between regions; and (2) the current practice on multiplicity adjustment and sample size calculation. This article provides a summary of the results of a survey on the first issue.

The survey was conducted among 63 members of the Japan Pharmaceutical Manufacturers Association from October to November 2017.

Thirty-five companies based in Japan and 12 companies based in other countries, 47 companies in total, responded to the survey. The terms co-primary endpoints, secondary endpoint, and composite endpoint were used in a variety of ways. An endpoint for a clinically most important event that is expected to occur rarely differed between regions. Although the Pharmaceuticals and Medical Devices Agency did not demand multiplicity adjustment, it was considered in clinical trials with multiple endpoints for approval in Japan.

The use of terminology differed from the definition in the Food and Drug Administration guidance and the European Medicines Agency guideline. There remain challenges on a clinically most important event that is expected to occur rarely and multiplicity adjustment in clinical trials with multiple endpoints.

The analysis of subgroups in clinical trials is essential to assess differences in treatment effects for distinct patient clusters, that is, to detect patients with greater treatment benefit or patients where the treatment seems to be ineffective.

The software application subscreen (R package) has been developed to analyze the population of clinical trials in minute detail. The aim was to efficiently calculate point estimates (eg, hazard ratios) for multiple subgroups to identify groups that potentially differ from the overall trial result. The approach intentionally avoids inferential statistics such as P values or confidence intervals but intends to encourage discussions enriched with external evidence (eg, from other studies) about the exploratory results, which can be accompanied by further statistical methods in subsequent analyses. The subscreen application was applied to 2 clinical study data sets and used in a simulation study to demonstrate its usefulness.

The visualization of numerous combinedespecially in joint interdisciplinary study teams. With the new application, an easily executed but powerful tool is provided to fill this gap.
In the process of research and development of a new treatment, clinical trials are conducted to evaluate its safety and efficacy. Key to streamlining the process is to utilize appropriate historical information on an outcome of a control treatment when designing and analyzing a clinical trial.

For the use of such historical control information, there exist a meta-analytic approach and power prior approach. In this article, we evaluate their performance with regard to the type I error (TIE) rate and power through a simulation study where we analyze the data on a binary outcome of an experimental treatment and a control treatment from a new small-scale trial, along with the corresponding data of the control treatment from multiple historical trials. The reason is that the difference in the performance between the 2 approaches has not been clear.

When historical trials were homogeneous, the power was higher in the power prior approach and the meta-analytic approach using a beta-binomial model with a less noninformative prior than the other approaches. Disufenton datasheet However, when heterogeneous historical trials were mixed, the power was lower, or the TIE rates got inflated.

To make use of historical control data, if importance is attached to control of the TIE rate, the meta-analytic approach using a normal-normal hierarchical model may be preferable to the power prior approach, whereas if attached to improvement of the power, this preference be reversed. Anyway, the best approach should be chosen by comparing the operational characteristics of the approaches.

"Patient experience data" (PED) refers to the systematic collection of meaningful data relating to the experiences, perspectives, needs, and priorities of patients. PED can augment traditional clinical trial data in the FDA's review of product applications. Section 3001 of the 2016 21st Century Cures Act requires the FDA to make a public statement about the PED considered in the approval of a drug application. Here, we present one of the first assessments of PED consideration during drug application approval, as reported by the FDA under Sec. 3001 of the Cures Act.

FDA reported use of PED in the Review Documentation of the 59 new molecular entities (NMEs) approved in 2018 were collected, indexed, and cross-referenced against information regarding FDA review and product regulatory designation. The data reported in the PED tables were quantitatively described and visualized.

Of the 59 approved NMEs in 2018, 48 include a table that summarized whether PED was or was not used during the FDA drug review. Thirty-four of those 48 approvals (70.8%) reported using PED in the drug review. Patient-reported outcomes(PROs) represented the most significant source of PED and were used in 60.4% of approved drug reviews. Additional findings, including PED use by FDA review division and by FDA regulatory designation, are described.

This assessment is a first step to better understanding how FDA considers PED in regulatory decision making. This analysis should help develop a baseline regarding FDA use of PED and may inform decisions to ensure patients' experiences are adequately heard in future drug development.

The unavailability of appropriate pediatric drug pack size is a global issue. Antibiotics are the lifesaving and most frequently prescribed therapeutic agents given to pediatrics. The objective of this study was to assess the compliance of pediatric antibiotic pack size with the standard dosage regimen.

A descriptive study design was employed. Data were collected from a community pharmacy in Bahawalpur, Pakistan, between August 1, 2017, and September 30, 2017. Five most commonly prescribed antibiotics were selected and calculations were made to check the appropriateness of packaging size by comparing the quantity of product in the available pack with the dosage regimen recommended by the British National Formulary for Children (BNFC).

Only 16 clarithromycin, 9 amoxicillin, 1 cefotaxime, and 1 metronidazole packaging sizes were sufficient to meet the dosage regimen for treatment. None of the available pack sizes for gentamicin matched the recommended duration of treatment. The study findings revealed that the available pack sizes either had leftover or a shortfall of antibiotic formulation. Highly inappropriate dosage forms (containing either excess and less quantity) of antibiotics were intravenous infusions and oral suspensions.

The study concluded that the packaging sizes of antibiotics failed to supply the recommended dosage regimen to pediatrics for common indications. This may contribute to development of antibiotic resistance among pediatric patients. Health policy makers should devise strict rules and regulations to ensure the availability of child-specific antibiotic pack sizes.

Informed consent is an important aspect of ethical medical practice. In legal terms, making an intervention without informed consent may mean negligence or malpractice and may lead to legal action, maltreatment, and even attack against the doctor. This study aims to evaluate the readability of informed consent forms (ICFs) used for elective (urology and general surgery) and emergency procedures (emergency medicine and intensive care) by comparing through readability formulas.

Elective and emergency ICFs were accessed through the web sites of national health care associations. A total of 387 consent forms were evaluated and the same forms were included only once. A total of 35 consent forms were evaluated for emergency procedures, while a total of 55 consent forms were evaluated for elective procedures. Ateşman and Bezirci-Yılmaz formulas defined for determining the readability level of Turkish texts and Gunning fog and Flesch Kincaid formulas measuring the general readability level were used for calculatile to be able to explain morbidity and mortality and improve prognosis. Education level of our country should also be considered while preparing these consent forms.
(1) A growing number of pharmaceutical and biotechnology organizations are engaging patients, their support networks, and clinical trial site staff at various touchpoints along the clinical research development spectrum to solicit feedback on how to reduce the burden of clinical trial participation and administration. (2) However, many organizations are still evaluating how to best implement such engagement initiatives in a manner that will evoke meaningful, sustainable results and change.

In an effort to support meaningful engagement in a novel way, Janssen organized a 2-day innovative workshop designed to promote collaboration and foster mutual understanding among a cross-functional group of clinical research stakeholders. Over the course of the workshop, patients, sponsor team members, and clinical trial site staff each leveraged their unique experiences to address the challenges of today's clinical trials, and collectively envision the ideal clinical trial of the future.

The workshop design created gagement option for other organizations to consider adopting.Victims of bullying are at increased risk of developing psychosocial problems. It is often claimed that it helps victims when others stand up against the bullying and when defending is typical (descriptive norm) or rewarded with popularity (popularity norm) in classrooms. However, recent work on the healthy context paradox suggests that victims - paradoxically - tend to do worse in more positive classrooms. Therefore, it is possible that defending norms are counterproductive and exacerbate victims' adjustment difficulties, possibly because social maladjustment is more apparent in classrooms where everybody else is doing well. The current study examined whether descriptive and popularity norms for defending predicted victims' classroom climate perceptions and psychosocial adjustment. Using data of 1,206 secondary school students from 45 classrooms (Mage = 13.61), multi-level analyses indicated that descriptive norms for defending increased rather than decreased negative classroom climate perceptions and maladjustment of victimized youths.
