protocol. A clinical trial protocol is a document describing how a <a href=\"https:\/\/www.kolabtree.com\/find-an-expert\/subject\/clinical-trials?utm_source=Blog&amp;utm_medium=Post&amp;utm_campaign=ClinicalTrialProtocol\">clinical trial<\/a> will be conducted, including the objective(s), design, methodology, statistical considerations, and organization of the trial to guarantee the safety of the participants and the integrity of the collected data. The protocol also provides the background and rationale for conducting the study and the <a href=\"https:\/\/www.kolabtree.com\/blog\/ensuring-reproducibility-in-ai-driven-research-how-freelance-experts-can-help-in-biotech-and-healthcare\/\">research<\/a> questions that it addresses, as well as considerations on ethical issues.

The synopsis is a short document listing the primary and secondary objectives of the clinical study and providing an overview of the study design and details about treatment(s). You can find an example of protocol synopsis from the World Health Organization in this<\/span><a href=\"https:\/\/www.who.int\/immunization\/research\/implementation\/infant_schedule_synopsis_rct.pdf?ua=1\"> <span style=\"font-weight: 400;\">link<\/span><\/a><span style=\"font-weight: 400;\">.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">The protocol synopsis and the complete protocol document should be prepared following ICH E6 compliant templates to ensure consistency and the inclusion of all key elements. The protocol synopsis includes the following information: study title, product, clinical phase, protocol number, disease indication, trial identification number, information about sponsor and investigator, and information about clinical sites. Moreover, the synopsis describes the objectives, study design, study population, sample size, eligibility criteria (for inclusion and exclusion), treatment, and type and timing of assessment based on objectives (with a clear schedule or flowchart). A precise definition of the objectives and the study design increases the efficiency of writing and avoids inconsistencies. Sample size calculation should be based on the primary objective, with additional objectives categorized as secondary.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">After preparing the protocol synopsis, the whole protocol can be developed. The complete protocol includes additional elements (listed below), such as the introduction (including clinical and non-clinical data), the rationale, a more detailed description of the assessments, the description of statistical methods, prior or concomitant treatments, and the conditions under which the study needs to be suspended or cancelled.<\/span><\/p>\n<h2><span class=\"ez-toc-section\" id=\"Topics_included_in_a_clinical_trial_protocol\"><\/span><b>Topics included in a clinical trial protocol<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">The<\/span><a href=\"https:\/\/ichgcp.net\/6-clinical-trial-protocol-and-protocol-amendments\/\"> <span style=\"font-weight: 400;\">ICH website<\/span><\/a><span style=\"font-weight: 400;\"> reports the full list of topics that should be included in the protocol.

A well-written and detailed protocol increases the likelihood of obtaining high-fidelity data, minimizes the need for protocol amendments, and facilitates the preparation of other documents such as research protocols, <a href=\"https:\/\/www.kolabtree.com\/find-an-expert\/subject\/manuscript-and-journal-article-writing\">manuscript writing<\/a>, presentations, etc. <\/span><\/p>\n<p><span style=\"font-weight: 400;\">Some relevant<\/span><a href=\"https:\/\/orra.rutgers.edu\/sites\/orra.rutgers.edu\/files\/HSPP\/HealthSci\/10_Kinetiq_WP_BestPracticesinClinicalResearchProtocolWriting-EighttipsfromanIRBmember_020416%281%29.pdf\"> <span style=\"font-weight: 400;\">tips<\/span><\/a><span style=\"font-weight: 400;\"> for clinical trial protocol writing include:<\/span><\/p>\n<ul>\n<li><span style=\"font-weight: 400;\">Always follow protocol content guidelines and address all items included in the guideline.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">The background of the protocol should mention all relevant preclinical and clinical data, including published and unpublished data.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">All research-related activities should be detailed in the protocol and the consent form. It is important to ensure the consistency of both documents. Moreover, research-related activities must be linked to a research aim.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Describe in detail all study activities that participants will undergo.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Getting an independent review of the protocol from colleagues that are not directly involved in the research plan can be very useful. It can help to identify potentially &#8216;unclear&#8217; aspects, where regulatory agencies and the IRB may have difficulties as well.<\/span><\/li>\n<li><span style=\"font-weight: 400;\">Consider the perspectives of the regulatory agencies (mainly focused on the &#8216;public good&#8217;) and the IRB (concerned with the rights and welfare of the individual subjects). Both perspectives are complementary but distinct. Invasive procedures or treatments should be minimized. The minimization of risks is particularly important in children and other vulnerable populations. In some cases, you may need to seek advice from an IRB regulatory consultant.<\/span><\/li>\n<\/ul>\n<h2><span class=\"ez-toc-section\" id=\"The_importance_of_public_availability_of_clinical_trial_protocols\"><\/span><b>The importance of public availability of clinical trial protocols<\/b><span class=\"ez-toc-section-end\"><\/span><\/h2>\n<p><span style=\"font-weight: 400;\">Protocol sharing can facilitate the critical appraisal of clinical trials (both the internal and external validity) and help to identify and prevent a selective reporting of outcomes and analyses. Making protocols publicly available increases the transparency of research while enabling scientists and prospective participants to learn about ongoing clinical trials. However, protocol sharing remains relatively rare (you can read more about the challenges<\/span><a href=\"https:\/\/trialsjournal.biomedcentral.com\/articles\/10.1186\/s13063-018-2510-1\"> <span style=\"font-weight: 400;\">here<\/span><\/a><span style=\"font-weight: 400;\">). Several open-access journals encourage the submission and publication of protocols, such as <\/span><i><span style=\"font-weight: 400;\">Trials <\/span><\/i><span style=\"font-weight: 400;\">(where more than half of publicly available trial protocols have been published. <\/span><i><span style=\"font-weight: 400;\">Trials<\/span><\/i><span style=\"font-weight: 400;\"> also promotes the use of a<\/span><a href=\"https:\/\/trialsjournal.biomedcentral.com\/submission-guidelines\/preparing-your-manuscript\/study-protocol\/structured-study-protocol-template\"> <span style=\"font-weight: 400;\">structured protocol template<\/span><\/a><span style=\"font-weight: 400;\"> for randomized trials), <\/span><i><span style=\"font-weight: 400;\">BMJ Open<\/span><\/i><span style=\"font-weight: 400;\">, and <\/span><i><span style=\"font-weight: 400;\">JMIR Research Protocols<\/span><\/i><span style=\"font-weight: 400;\">. Take into account that several medical journals -such as <\/span><i><span style=\"font-weight: 400;\">The Lancet<\/span><\/i><span style=\"font-weight: 400;\"> and <\/span><i><span style=\"font-weight: 400;\">PLOS Medicine<\/span><\/i><span style=\"font-weight: 400;\">&#8211; require the inclusion of clinical trial protocols when submitting a clinical research article.<\/span><\/p>\n<p><span style=\"font-weight: 400;\">Accurately writing your clinical trial protocol and making it publicly available will greatly benefit patients and other users of evidence from clinical trials.<\/span><\/p>\n<blockquote><p><strong>Need to hire a <a href=\"https:\/\/www.kolabtree.com\/find-an-expert\/subject\/clinical-trial-protocol-writing\">freelance clinical trial protocol writer<\/a>?
