Science- and Risk-Based Stability Strategies to Support Product Lifecycle Changes.

ICH Q12 asserts that science- and risk-based approaches are applicable to stability studies supporting Chemistry, Manufacturing and Controls (CMC) post-approval changes (PAC) to enable more timely implementation; however, no guidance or specific examples are provided to demonstrate how prior knowledge of the product can inform the risk assessment for the proposed change(s). Ten diverse case studies are presented in this manuscript to demonstrate how science- and risk-based stability strategies were used to support drug substance and product CMC PAC and lifecycle management activities. The accumulated stability knowledge held by original manufacturers of marketed products is substantial, and different elements of this knowledge base were used to assess the risks and impact of the proposed changes for confident change management.

Industry Perspective on Temperature Cycling Studies to Meet Regulatory Temperature Excursion Support Requirements: Survey Outcome and Recommendations.

Temperature cycling stability studies can be appropriately designed and utilized to ensure that drug product quality, efficacy, and safety are not compromised when materials are subjected to short term temperature excursions from intended storage that may occur during e.g., shipping, transport, or patient use.

Meeting Report: Vaccine Stability Considerations to Enable Rapid Development and Deployment.

The Stability Community of the American Association of Pharmaceutical Scientists (AAPS) held a virtual workshop on "Vaccine Stability Considerations to Enable Rapid Development and Deployment", on March 24-25, 2021. The workshop included distinguished speakers and panelists from across the industry, academia, regulatory agencies, as well as health care leaders. This paper presents a review of the topics covered.

Considerations for Updates to ICH Q1 and Q5C Stability Guidelines: Embracing Current Technology and Risk Assessment Strategies.

In consideration of the recent ICH Quality Discussion Group (QDG) recommended revision to the ICH series of stability guidelines, the IQ Consortium (International Consortium for Innovation and Quality in Pharmaceutical Development) Science- and Risk-based Stability Working Group conducted a comprehensive review of ICH Q1A, Q1B, Q1C, Q1D, Q1E, and Q5C to identify areas where the guidelines could be clarified, updated, and amended to reflect the potential knowledge gained from current risk-based predictive stability tools and to consider other science- and risk-based stability strategies in accordance with ICH Q8-12. The recommendations propose a holistic approach to stability understanding, utilizing historical data, prior knowledge, modeling, and a risk assessment process to expand the concept of what could be included (or would be acceptable) in the core stability data package, including type and amount of stability evidence, assignment of retest period and shelf-life for a new product, and assessment of the impact of post-approval changes.
