SOP for Preparing Preclinical Study Protocols

Standard Operating Procedure (SOP) for Preparing Preclinical Study Protocols

1) Purpose

The purpose of this Standard Operating Procedure (SOP) is to provide a standardized approach for preparing preclinical study protocols. Preclinical study protocols ensure that all aspects of the study, such as design, animal welfare, regulatory compliance, and safety standards, are addressed in a systematic and organized manner. A well-prepared protocol ensures that the study is scientifically valid, reproducible, and compliant with ethical guidelines.

2) Scope

This SOP applies to all personnel involved in the preparation, review, and approval of preclinical study protocols. This includes study directors, project managers, regulatory affairs teams, quality assurance, and animal care staff. It covers the preparation of protocols for safety, efficacy, pharmacokinetics, and toxicity studies in preclinical drug development.

3) Responsibilities

Study Directors: Responsible for overseeing the preparation of study protocols, ensuring they meet scientific and regulatory requirements.
Project Managers: Responsible for ensuring that protocols are prepared according to timelines and resource allocation is managed effectively.
Regulatory Affairs: Ensures that all study protocols comply with regulatory guidelines (e.g., FDA, ICH, EMA) and animal welfare standards.
Quality Assurance (QA): Responsible for reviewing and auditing protocols to ensure compliance with internal standards, GLP, and regulatory guidelines.
Animal Care and Laboratory Staff:

Responsible for providing feedback on animal care requirements, study design, and ensuring proper tissue collection and handling procedures.

4) Procedure

The following steps outline the procedure for preparing a preclinical study protocol:

Step 1: Study Objective and Design
1. Define the study objective, including the research question and intended outcomes (e.g., drug efficacy, safety, toxicity).
2. Identify the endpoints for the study, including primary (e.g., pharmacokinetics, therapeutic response) and secondary endpoints (e.g., biomarkers, organ function).
3. Determine the appropriate animal model based on the study’s objective, such as rodents, non-human primates, or other species.
4. Specify the study design, including the number of animals, treatment arms, dose levels, administration routes, and control groups.
Step 2: Ethical and Regulatory Review
1. Submit the study protocol for review and approval by the Institutional Animal Care and Use Committee (IACUC) or an equivalent ethics body to ensure compliance with animal welfare standards.
2. Ensure that the study complies with regulatory guidelines from relevant authorities (e.g., FDA, ICH, EMA), including safety and data reporting requirements.
3. Document all necessary approvals and amendments from ethical and regulatory bodies.
Step 3: Protocol Review and Approval
1. Circulate the protocol for internal review among relevant stakeholders, such as study directors, regulatory affairs, and animal care personnel.
2. Ensure that all feedback and suggested amendments are incorporated into the final version of the protocol before approval.
Step 4: Resource Allocation and Scheduling
1. Ensure that necessary resources, including animals, laboratory space, and equipment, are allocated according to the study protocol.
2. Schedule the study timeline, taking into account all necessary preparations, study phases, and follow-up analyses.
Step 5: Final Documentation
1. Ensure that the final version of the protocol is documented, reviewed, and signed off by authorized personnel.
2. Maintain a record of all protocol drafts, correspondence, approval documents, and revisions as part of study documentation.
