Guidelines for Compliance with Health Canada Stability Testing Requirements
1) Purpose
The purpose of this Standard Operating Procedure (SOP) is to provide guidelines for ensuring that stability studies comply with Health Canada’s requirements for drug substances and drug products. This SOP ensures that stability data supports the quality, safety, and efficacy of products throughout their shelf life in the Canadian market.
2) Scope
This SOP applies to all personnel involved in the design, execution, and documentation of stability studies for drug substances and drug products intended for the Canadian market.
3) Responsibilities
Stability Testing Team: Responsible for conducting stability studies and documenting results in compliance with Health Canada 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 Health Canada regulatory expectations.
4) Procedure
4.1 Preparation for Stability Testing
4.1.1 Obtain and review the latest Health Canada
guidelines for stability testing of drug substances and drug products.4.1.2 Develop a stability protocol that includes study design, testing schedule, storage conditions, and testing parameters as per Health Canada guidelines.
4.2 Selection of Batches and Samples
4.2.1 Select representative batches of the product, 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 time points and tests to be conducted.
4.3 Defining Storage Conditions and Time Points
4.3.1 Define the storage conditions according to Health Canada guidelines, typically including:
- Long-term stability: 25°C ± 2°C/60% RH ± 5% RH or 30°C ± 2°C/65% RH ± 5% RH, depending on the product type
- Accelerated stability: 40°C ± 2°C/75% RH ± 5% RH
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, monitoring temperature and humidity to ensure compliance with the set parameters.
4.4.2 At each specified time point, remove samples and conduct stability-indicating tests, including physical, chemical, microbiological, and functional tests, as applicable.
4.4.3 Record all results meticulously in stability data sheets, ensuring accuracy and traceability of data.
5) Abbreviations, if any
QA: Quality Assurance
