The document outlines the key elements of a successful clinical trial protocol. A protocol is a document that provides guidelines for a clinical trial, including its objectives, design, methodology, and organization. It aims to obtain appropriate data on a drug's clinical properties within the shortest timeline and at minimal cost, while ensuring patient safety and adherence to regulatory standards. The document discusses 10 essential elements for an effective protocol: medical expertise, prior experience, hypothesis, endpoints, safety measures, credibility, rationality, structure, simplicity, and legitimacy. It emphasizes the importance of a protocol in providing clear guidelines to ensure a clinical trial's objectives are achieved efficiently and ethically.

CLINICAL TRIAL PROTOCOL
• A document that describes the objective(s), design,
methodology, statistical considerations, and
organization of a trial.
ICH GCP, GOST Р 52379-2005 «Good Clinical Practice»
• A document that defines objectives, organization and
methodology of a clinical study, statistical methods
of results analysis and measures to assure safety of
clinical trial subjects.
Russian Federal Law dated April 12, 2010 N 61-ФЗ «On circulation of
medicinal products»

THE ESSENCE OF A CLINICAL TRIAL
PROTOCOL
• Form: Clear structured guideline for all parties involved in a
clinical trial
• Objective: To obtain appropriate data on clinical properties of
a drug within the shortest timeline and at minimal cost with
due consideration of the following:
• Medical and scientific relevance and justification
• Treatment and/or safety assurance of patients
• Regulatory requirements and GCP guidelines
• Outcome: Data sufficient to make a decision of drug
registration, shift over to the next phase, additional research
or ending of the clinical program
