Making sense of phase appropriate analytical methods
Meeting regulatory requirements with accuracy and precision across the full lifecycle
Each phase of clinical trials has specific analytical requirements, with the level of data and details increasing as an API progresses into further stages of the lifecycle. In order to meet regulatory requirements and avoid cost overruns and delays, it is important to tailor the analytical approach to each respective phase. Coupling deep analytical chemistry expertise with a global regulatory perspective is critical for generating high quality results.

Analytical methods and the importance of a phase specific approach
Given that only a small proportion of products that enter clinical trials reach commercialisation, organisations want to avoid overspending on analytical work in the earliest phases of their project. However, they must also reach the core analytical validation criteria required at each stage, as well as generate quality results for their own benefit. Having a stringent focus on the necessary quality and regulatory requirements at each phase can allow organisations to progress through clinical trials as eciently as possible while ensuring regulatory compliance.
How should you tailor your analytical approach at each phase?
To enhance efficiency, contain costs, and ensure regulatory success, a tailored approach to analytical method development is critical. Let’s take a closer look at each phase of the pharmaceutical lifecycle and the analytical standards that should be applied at each.

Before clinical trials begin, there are no formalised data requirements from a regulatory standpoint. At this stage, it is important to achieve reliable results using scientifically sound analytical methods.
During Phase I, official regulatory requirements begin, as the target molecule is given to small groups of healthy individuals. Analytical protocols and reports are formulated in a memo style and reviewed from more of a technical standpoint than a quality one. Methods should be scientifically sound and fit for purpose.

Testing in Phase II is similar to Phase I, but becomes a more formal exercise. Specific analytical methods are defined in advance, and the protocols and reports go through a full quality assurance review. Testing during Phases I and II cover the core method validation characteristics, with more characteristics evaluated during Phase III and commercial level validations.

In Phase III, the level of formality increases further, and organisations expect to reach commercialisation at this point. While only proof that methods can be validated is required, many organisations choose to perform full analytical validation at this phase to avoid repeating upon commercialisation. This phase involves a more formalised validation approach, including demonstrating method performance across an expanded range of validation characteristics

Full analytical validation is necessary once a product reaches commercialisation. Robustness testing is included to stress test the method by systematically altering method parameters to ensure the method performs under a broad range of operating and environmental conditions. Testing is performed by multiple analysts and multiple instruments to ensure accurate, reliable results can be achieved repeatedly as product reaches the market.
