Q1 Scientific Webinars

Following feedback from customers we have created the Q1 Scientific webinar series. This series is designed for those working in the pharmaceutical, medical device, food and cosmetics sectors with responsibility for designing and managing stability studies.

If you missed our live webinars then the good news is that we recorded them all for you. You can now catch-up online using the links below.

All our webinars aim to provide an insight into stability study design and what it means for you. During the webinars Dr. Mark Powell shares his experience and addresses key questions.

Stability Studies throughout the Product Life Cycle

Join Dr. Mark Powell as he looks at the various stability studies conducted from the start of pharmaceutical development to the manufacture of marketed product. Dr. Mark Powell also explains the purpose of each study and highlights some of the potential pitfalls.

Topics covered include:
• Aims of stability evaluation
• The effect of environmental factors and the primary pack
• API stability
• Excipient compatibility
• Prototype stability (including accelerated stability using the ASAP model and stress stability studies)
• Bulk hold studies
• In-use stability
• Registration stability
• Shipping excursion studies

Designing a Registration Stability Study from Scratch

Register now to view our recent webinar where Dr. Mark Powell discussed designing a registration stability study from scratch.

The aim of this webinar was to provide guidance on the design of long-term stability studies in support of a MAA or NDA.  As well as describing the general requirements for different dosage forms, differences in expectations between EU and US regulators were highlighted.  Depending on the dosage form and pack type, certain risks require mitigation prior to registration batch manufacture and stability set-down: these were also discussed.  Confidence in test methods and a plan for low-level impurity data reporting are also important elements.  Finally, study designs were discussed, including different product configurations and requirements for registration in Climatic Zones III and IV.

Topics covered included:

  • Regulatory expectations for different dosage forms
  • Product knowledge
  • Test method and data reporting considerations
  • Study design
  • Different strengths/primary pack configurations
  • Considerations for global registration

Trending Stability Data

Pharmaceutical regulators have made it clear that the same investigation approach should be adopted for out-of-trend (OOT) results as for out-of-specification (OOS) results. However, regulators offer little guidance on identifying OOT data.  For OOT results to be identified promptly during stability studies, data must be continuously trended in some way.  The problem is that trends are often not obvious during the early phases of a stability study.  This webinar offers some practical approaches for the continuous trending of stability data and covers:

  • Regulatory expectations for OOT results
  • When is a result OOT?
  • Identifying OOT results
    • Regression control chart
    • By-time-point method
    • Slope control chart method

Shelf Life Evaluation and Extrapolation

This webinar explains how to set a retest period for a drug substance or shelf life for the drug product.  It also describes how extrapolation can be applied to propose a retest period or shelf life for a drug product that extends beyond the period covered by real-time stability data.  It covers regulatory guidance, poolability of stability data and appropriate statistical models for shelf-life evaluation. Topics covered include:

  • Overview of ICH Q1E – Evaluation for Stability Data
  • Shelf-life extrapolation
  • Statistical background to ICH Q1E
  • Evaluating poolability of stability data – analysis of covariance
  • Examples – potency and impurity trends

Temperature Excursion and Cycling Studies

Temperature excursions during shipment can cause the recall of drug product lots, leading to delays in supply and loss of revenue.  Data from a well-conducted temperature excursion and/or cycling study can be used to justify such excursions.  There is currently no harmonised guidance dealing with the impact of temperature excursions during distribution or the effect of freeze/thaw cycles on liquids and semi-solids.  This webinar reviews best practice in these areas. Topics covered include:

  • Overview of regulatory guidance
  • Temperature excursion risks to physical and chemical product stability
  • Evaluating possible excursions using supply chain knowledge
  • Temperature excursion studies
  • Thermal cycling studies
  • Transportation control strategy

Biopharmaceutical Stability Studies

Stability is a particular problem for biopharmaceutical products because the physical and chemical stability of peptides and proteins are often very sensitive to storage and transportation conditions. The purpose of this webinar is to explain the typical approach for the design of a stability study for biologics.  The webinar also covers the specific challenges of these product types as well as typical degradation mechanisms. Topics covered include:

  • Overview of ICH Q5C – Stability testing of biotechnological/biological products
  • Specific stability challenges for biologics
  • Protein and peptide degradation pathways
  • Evaluating stability – typical tests
  • In-use stability
  • Stability after reconstitution

Stability Study Design – Bracketing and Matrixing

Stability programmes are a costly undertaking, especially for products that have multiple strengths and packaging configurations, where a full study design will require every configuration to be evaluated for three registration batches at each time point.  The use of reduced study designs such as bracketing and matrixing can reduce the cost of formal stability studies.  This webinar describes when the use of such approaches is allowable, together with their associated benefits and risks. Topics covered include:

  • Overview of ICH Q1D – Bracketing and Matrixing Designs
  • Bracketing study designs
  • Bracketing study risks
  • Matrix study designs
  • Matrix study risks
  • Combined bracketing and matrix study designs
  • Summary of risks and benefits
