Clinical Research Toolkit Clinical Research Toolkit Through collaboration with multiple research disciplines, the documents below were created to assist investigators and research teams at various timepoints throughout a clinical research study. They are geared towards investigator-initiated or investigator-sponsor research studies where the investigator has more responsibilities, and represent the local vision for the conduct of clinical research at the UW-Madison. The templates and tools are to be used as guidance; research teams are not required to follow the documents exactly. Some of the documents or tools are not applicable to all studies. Also, the nature of some research may warrant the development or use of additional tools related to specific research specialties or subject populations. Additionally, some sponsors, CROs, or federal agencies may require that investigators keep additional documents that are not specifically referenced in this guidance. If you have questions regarding the tools, or other compliance related questions in general, email compliance lists.

The National Scientific Committees were administered by Bellberry Limited, a private not-for-profit organisation providing scientific and ethical review of human research projects across Australia. A report from the pilot is available below - see 'download' section. The pilot found that the use of a panel of experts to provide a scientific opinion on research proposals was considered valuable by researchers, sponsors and HRECs.

The pilot found that demand was greatest for early phase clinical trial proposals, with trials involving medical devices benefiting to a lesser extent from the National Scientific Committees.

There was little demand for reviews of complex genetic research proposals. Given that demand was concentrated on early phase clinical trials, and as a number of jurisdictions and groups have since developed their own initiatives to improve the scientific review of early phase clinical trials including through the better identification of individuals and bodies with appropriate expertise , NHMRC is not proposing to continue with the National Scientific Committees. Information on the NSW early phase clinical trials initiative can be found here.

In California , the state has prioritized the individuals who can serve as the legally authorized representative. The International Conference of Harmonisation Guidelines for Good Clinical Practice is a set of standards used internationally for the conduct of clinical trials.

The guidelines aim to ensure the "rights, safety and well being of trial subjects are protected". The notion of informed consent of participating human subjects exists in many countries all over the world, but its precise definition may still vary.

Informed consent is clearly a 'necessary' condition for ethical conduct but does not 'ensure' ethical conduct.

In compassionate use trials the latter becomes a particularly difficult problem. The final objective is to serve the community of patients or future patients in a best-possible and most responsible way. See also Expanded access. However, it may be hard to turn this objective into a well-defined, quantified, objective function. In some cases this can be done, however, for instance, for questions of when to stop sequential treatments see Odds algorithm , and then quantified methods may play an important role.

Additional ethical concerns are present when conducting clinical trials on children pediatrics , and in emergency or epidemic situations. Similarly, competition for tenured academic positions, government grants and prestige create conflicts of interest among academic scientists.

They strengthened editorial restrictions to counter the effect. Researchers may be restricted from contributing to the trial design, accessing the raw data, and interpreting the results. For safety reasons, many clinical trials of drugs [65] are designed to exclude women of childbearing age, pregnant women, or women who become pregnant during the study.

In some cases, the male partners of these women are also excluded or required to take birth control measures. Sponsor[ edit ] Throughout the clinical trial, the sponsor is responsible for accurately informing the local site investigators of the true historical safety record of the drug, device or other medical treatments to be tested, and of any potential interactions of the study treatment s with already approved treatments.

This allows the local investigators to make an informed judgment on whether to participate in the study or not. The sponsor is also responsible for monitoring the results of the study as they come in from the various sites as the trial proceeds. In larger clinical trials, a sponsor will use the services of a data monitoring committee DMC, known in the US as a data safety monitoring board.

This independent group of clinicians and statisticians meets periodically to review the unblinded data the sponsor has received so far. The DMC has the power to recommend termination of the study based on their review, for example if the study treatment is causing more deaths than the standard treatment, or seems to be causing unexpected and study-related serious adverse events.

The sponsor is responsible for collecting adverse event reports from all site investigators in the study, and for informing all the investigators of the sponsor's judgment as to whether these adverse events were related or not related to the study treatment.

The sponsor and the local site investigators are jointly responsible for writing a site-specific informed consent that accurately informs the potential subjects of the true risks and potential benefits of participating in the study, while at the same time presenting the material as briefly as possible and in ordinary language.

FDA regulations state that participating in clinical trials is voluntary, with the subject having the right not to participate or to end participation at any time. November Learn how and when to remove this template message The ethical principle of primum non nocere "first, do no harm" guides the trial, and if an investigator believes the study treatment may be harming subjects in the study, the investigator can stop participating at any time.

On the other hand, investigators often have a financial interest in recruiting subjects, and could act unethically to obtain and maintain their participation.

The local investigators are responsible for conducting the study according to the study protocol, and supervising the study staff throughout the duration of the study. In other words, they or their legally authorized representatives must give truly informed consent.

Local investigators are responsible for reviewing all adverse event reports sent by the sponsor. These adverse event reports contain the opinion of both the investigator at the site where the adverse event occurred, and the sponsor, regarding the relationship of the adverse event to the study treatments. Local investigators also are responsible for making an independent judgment of these reports, and promptly informing the local IRB of all serious and study treatment-related adverse events.

When a local investigator is the sponsor, there may not be formal adverse event reports, but study staff at all locations are responsible for informing the coordinating investigator of anything unexpected. The local investigator is responsible for being truthful to the local IRB in all communications relating to the study. In commercial clinical trials, the study protocol is not approved by an IRB before the sponsor recruits sites to conduct the trial.

However, the study protocol and procedures have been tailored to fit generic IRB submission requirements.

In this case, and where there is no independent sponsor, each local site investigator submits the study protocol, the consent s , the data collection forms, and supporting documentation to the local IRB.

Universities and most hospitals have in-house IRBs. Other researchers such as in walk-in clinics use independent IRBs. The IRB scrutinizes the study for both medical safety and protection of the patients involved in the study, before it allows the researcher to begin the study.

It may require changes in study procedures or in the explanations given to the patient. A required yearly "continuing review" report from the investigator updates the IRB on the progress of the study and any new safety information related to the study. Regulatory agencies[ edit ] In the US, the FDA can audit the files of local site investigators after they have finished participating in a study, to see if they were correctly following study procedures.

This audit may be random, or for cause because the investigator is suspected of fraudulent data. Avoiding an audit is an incentive for investigators to follow study procedures. A 'covered clinical study' refers to a trial submitted to the FDA as part of a marketing application for example, as part of an NDA or k , about which the FDA may require disclosure of financial interest of the clinical investigator in the outcome of the study.

For example, the applicant must disclose whether an investigator owns equity in the sponsor, or owns proprietary interest in the product under investigation. The FDA defines a covered study as " Benefits of conducting trials abroad include lower costs in some countries and the ability to run larger trials in shorter timeframes, whereas a potential disadvantage exists in lower-quality trial management.

At the same time, coordination between Europe, Japan and the United States led to a joint regulatory-industry initiative on international harmonization named after as the International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use ICH [70] Currently, most clinical trial programs follow ICH guidelines, aimed at "ensuring that good quality, safe and effective medicines are developed and registered in the most efficient and cost-effective manner.

All the potential serious DDIs were intimated to the treating physicians and their responses in the prescriptions were noted. The same patients were followed up to evaluate the occurrence of any clinically significant DDIs.

A total of drugs with discrete types were prescribed in patients with an average of 4. One hundred and eight minor, significant, and 24 serious potential DDIs were identified. There was a disparity between the potential and clinically relevant DDIs. Hence, clinical prudency is required before changing prescription due to potential DDIs reported by different software. This study aimed to evaluate the doctors' perspectives in using tools for diagnosis, prescribing medications, and devices for the treatment of asthma in Algeria.

Data were collected from randomly selected physicians, pediatricians, allergists, and pulmonologists through a questionnaire-based survey in 12 cities and 60 rural locations across Algeria.

The use of diagnostic tools in asthma was found to be adequate among the doctors in Algeria. Most of the doctors managed asthma in accordance with the global initiative for asthma guidelines. Spacers were found to be less prescribed in regular treatment, despite having good awareness about its better outcomes. Research in medicine has an impact on prevention, diagnosis, and newer treatment for the medical ailments.

It has brought reforms in policies for health-care programs. Involvement of undergraduates in research was less, so this study was planned to determine the factors and their perception toward the same. The objective of the study was to evaluate knowledge, attitude, experience, and the barriers of research among medical undergraduates. A cross-sectional questionnaire-based study was conducted after the protocol was approved by the Institutional Ethics Committee and obtaining written informed consent from participants.

The predesigned validated questionnaire containing 34 questions was used. Filled questionnaires were received from the medical undergraduates of different phases of MBBS from our institute. Data were analyzed using descriptive statistics.

Most of the participants had knowledge regarding research and expressed positive attitude toward involvement in research activity. Some of barriers were lack of awareness, time, funds, and difficulty in patient follow-up. In this retrospective cross-sectional study, we sought to evaluate if the published randomized controlled trials RCTs reported in the year among the Indian medical journals IMJs complied with the Consolidated Standards of Reporting Trials CONSORT guidelines and identify domains where reporting could be improved.

In the archives of the identified journals, the number of published RCTs was identified and the full text was obtained. We selected articles that stated RCT in abstract and title and that evaluated the safety and efficacy of all therapeutic and preventive interventions.

The mean compliance score of all the RCTs was Most RCTs had serious reporting deficiencies in the methodology and result sections. There is an urgent need to impart training to the medical community of our country in clinical research methods and reporting of RCTs.
