Registration audit of clinical trials given a favourable opinion by UK research ethics committees.

ABSTRACT: OBJECTIVE:To determine levels of public registration for a cohort of clinical trials reviewed and given a favourable opinion by research ethics committees in the United Kingdom. STUDY DESIGN:Audit of records. SETTING:Clinical trials receiving a favourable ethics opinion between 1 January 2016 and 30 June 2016. MAIN OUTCOME MEASURES:Correlation between trials on the UK research ethics committee database and any primary registry entry on the WHO International Clinical Trials Registry Platform or clinicaltrials.gov as of 29 August 2017 (14 to 20 months after the favourable ethics committee opinion). RESULTS:Over the study period 1014 trials received a favourable ethics opinion, with 397 (39%) registered on the European Union Drug Regulating Authorities Clinical Trials database, and 18 with an agreed clinical trial registration deferral. Excluding these trials, the total number subsequently requiring registration was 599, and of these 405 (40% of total) were found to be registered. Follow-up with the 194 investigators or sponsors of trials not found to be registered produced 121 responses with a further 10 (1%) trials having already registered, 55 commitments to register and a variety of other responses. The overall registration rate was therefore 80%. CONCLUSIONS:Despite researchers and sponsors being reminded that registration of clinical trials is a condition of the research ethics committee (REC) favourable opinion, one-fifth of clinical trials either had not been registered, or their registration could not easily be found, 14 to 20 months after receiving the favourable opinion letter. The methodology trialled here proved effective, and although there are positive indications of a culture change towards greater registration, our results show that more still needs to be done to increase trial registration.

Project description:ObjectivesTo assess the completeness of reporting of sample size determinations in unpublished research protocols and to develop guidance for research ethics committees and for statisticians advising these committees.DesignReview of original research protocols.Study selectionUnpublished research protocols for phase IIb, III, and IV randomised clinical trials of investigational medicinal products submitted to research ethics committees in the United Kingdom during 1 January to 31 December 2009.Main outcome measuresCompleteness of reporting of the sample size determination, including the justification of design assumptions, and disagreement between reported and recalculated sample size.Results446 study protocols were reviewed. Of these, 190 (43%) justified the treatment effect and 213 (48%) justified the population variability or survival experience. Only 55 (12%) discussed the clinical importance of the treatment effect sought. Few protocols provided a reasoned explanation as to why the design assumptions were plausible for the planned study. Sensitivity analyses investigating how the sample size changed under different design assumptions were lacking; six (1%) protocols included a re-estimation of the sample size in the study design. Overall, 188 (42%) protocols reported all of the information to accurately recalculate the sample size; the assumed withdrawal or dropout rate was not given in 177 (40%) studies. Only 134 of the 446 (30%) sample size calculations could be accurately reproduced. Study size tended to be over-estimated rather than under-estimated. Studies with non-commercial sponsors justified the design assumptions used in the calculation more often than studies with commercial sponsors but less often reported all the components needed to reproduce the sample size calculation. Sample sizes for studies with non-commercial sponsors were less often reproduced.ConclusionsMost research protocols did not contain sufficient information to allow the sample size to be reproduced or the plausibility of the design assumptions to be assessed. Greater transparency in the reporting of the determination of the sample size and more focus on study design during the ethical review process would allow deficiencies to be resolved early, before the trial begins. Guidance for research ethics committees and statisticians advising these committees is needed.

Project description:The review of requests for a positive opinion of the ethics committees (application procedure) as a requirement to start a clinical trial in Germany has been completely redesigned with the transposition of EU Directive 2001/20/EC in the 12(th) Amendment of the German Medicines Act in August 2004. The experience of applicants (sponsors, legal representatives of sponsors in the EU and persons or organizations authorized by the sponsors to make the application, respectively) in terms of interactions with the ethics committees in Germany has been positive overall, especially with respect to ethics committee adherence to the statutory timelines applicable for review of requests. However, inconsistencies between ethics committees exist in terms of the form and content of the requirements for application documents and their evaluation. With the objective of further improving both the quality of applications and the evaluation of those applications by ethics committees, a survey among members of the German Association of Research-Based Pharmaceutical Companies (VFA) was conducted from January to April 2008. Based on reasoned opinions issued by the respective ethics committee in charge of the coordinating principal investigator (coordinating ethics committee), the type and frequency of formal and content-related objections to applications according to section sign 7 of the German Good Clinical Practice (GCP) Regulation were systematically documented, and qualitative and quantitative analyses performed. 21 out of 44 members of the VFA participated in the survey. 288 applications for Phase I-IV studies submitted between January and December 2007 to 40 ethics committees were evaluated. This survey shows that about one in six applications is incomplete and has formal and/or content objections, respectively, especially those that pertain to documents demonstrating the qualification of the investigator and/or suitability of the facilities. These objections are attributable to some extent to the differing and/or unclear requirements of the individual ethics committees on the content and comprehension of the submission documents. However, applicants also need to pay more attention to the completeness and validity of the submission documents. The majority of content-related objections apply to the patient information and consent documents and study protocols submitted. Applicants on average acted upon only 3 out of 4 objections, for various reasons: the relevant information was already given in the submitted documents, but had not been taken into consideration by the ethics committees; objections were not applicable; objections lacked a legal basis. In such cases the applicants made reference to the specific information already submitted or gave reasons for not acting on the objection. This course of action was accepted by the ethics committees, with few exceptions. The survey sheds light on the existing inconsistencies in the evaluations of applications by the various ethics committees and suggests ways in which the existing constructive dialogue between applicants and ethics committees may provide a basis to further harmonize both the requirements regarding form and content of application documents, and the criteria for evaluation of applications by ethics committees within the legal framework.

Project description:BACKGROUND:Screening for Down's syndrome forms part of routine obstetric practice. Ethical considerations relating to genetic screening form a major part of the workload of research ethics committees. This study investigated the attitudes of research ethics committee members to several conditions varying in clinical severity and prognosis, including Down's syndrome. METHODS:The members of 40 randomly chosen research ethics committees were surveyed. A simple questionnaire comprising 19 clinical scenarios based around four "clinical" conditions was designed to review conditions that were potentially embarrassing, affecting life span but not mental ability, premature death, and intellectual impairment with a risk of neonatal cardiac defects (Down's syndrome). Screening tests with different degrees of effectiveness were described and the diagnostic test descriptions ranged from having no risk to an unaffected fetus to causing spontaneous abortion of two normal fetuses for each affected fetus identified. Replies were graded on a scale of 1 to 5. RESULTS:Seventy seven replies were received from 28 different research ethics committees. Screening was supported for treatment of a life threatening condition (95% in favour) but screening for conditions of a slight increase in premature death (14% in favour) or cosmetic features (10% in favour) were considered unethical. Views were ambiguous (49% in favour) about conditions involving significant shortening of lifespan. Down's syndrome screening was considered more ethical when described as a serious condition (56% in favour) than when the clinical features were described (44% in favour). Once increased rates of spontaneous abortion on confirmatory testing were added, 79% (21% in favour) and 86% (14% in favour) stated that screening was unethical (for "serious" and "clinical features" descriptions, respectively). CONCLUSIONS:Down's syndrome screening raises ethical concerns about genetic testing in general that need to be dealt with before the introduction of any prenatal screening test.
