Guidelines for Stability Testing of Radiopharmaceuticals as per ICH Guidelines
1) Purpose
The purpose of this Standard Operating Procedure (SOP) is to provide guidelines for conducting stability testing of radiopharmaceuticals in accordance with the ICH guidelines. This SOP ensures that stability data supports the quality, safety, and efficacy of radiopharmaceutical products throughout their shelf life.
2) Scope
This SOP applies to all personnel involved in the design, execution, and documentation of stability studies for radiopharmaceuticals intended for global markets.
3) Responsibilities
Stability Testing Team: Responsible for conducting stability studies and documenting results in compliance with ICH guidelines.
Quality Assurance (QA) Team: Responsible for reviewing and approving stability study protocols and reports.
Regulatory Affairs Team: Responsible for ensuring that stability studies meet the regulatory expectations of target markets.
4) Procedure
4.1 Preparation for Stability Testing
4.1.1 Obtain and review the latest ICH guidelines for stability testing of radiopharmaceuticals.
4.1.2 Develop a stability
4.2 Selection of Batches and Samples
4.2.1 Select representative batches of the radiopharmaceutical, typically three primary batches manufactured using the proposed production process.
4.2.2 Prepare sufficient samples to cover the entire study duration, considering the number of
4.3 Defining Storage Conditions and Time Points
4.3.1 Define the storage conditions according to ICH guidelines, considering specific requirements such as radiation safety, temperature, and light exposure.
4.3.2 Establish the time points for sampling, such as 0, 3, 6, 9, 12, 18, and 24 months for long-term studies, and additional time points for accelerated studies.
4.4 Conducting Stability Tests
4.4.1 Store samples under the defined conditions, ensuring compliance with radiation safety protocols and monitoring temperature and light exposure as required.
4.4.2 At each specified time point, remove samples and conduct stability-indicating tests, including radiochemical purity, sterility, and potency tests, as applicable.
4.4.3 Record all results meticulously in stability data sheets, ensuring accuracy and traceability of data.
