Design of Experiments (DOE) Software -  Enabling Quality by Design (QbD) 

DOE Software for Quality by Design (QbD) and Process Optimization

Ensure Product Robustness with Fewer Trials

When you need to ensure product robustness, define an optimal process or formula, or determine the best way to make changes or substitutions, you need a data analytics method and software tool that gives you confidence and simplifies your work. MODDE® Design of Experiments (DOE) Software is that tool.  

Design of Experiments (DOE) is a data analytics method that helps you plan, conduct, analyze and interpret controlled tests to determine which factors exert influence over your product quality, stability or other key process attributes.  Rather than experimenting with one parameter at a time, DOE speeds up the process and helps you identify important interactions by manipulating multiple factors at the same time. 

DOE supports a quality by design (QbD) approach to product development that is favored by regulatory agencies. By building experiment certainty and reproducibility into your process, you can be confident in the robustness of your formulation and quality of your final product.

DOE Supports Quality by Design (QbD)

DOE is an essential tool to ensure products and processes satisfy Quality by Design requirements imposed by regulatory agencies.  Using a QbD approach to develop your testing process can help you reduce waste, meet compliance criteria and get to market faster.  

DOE helps you create a reliable QbD process for assessing formula robustness, determining critical quality attributes and predicting shelf life by using a few months of historical data.

Why Use a Quality By Design Approach? 

Using a Quality by Design (QbD) approach to develop the testing process and to choose the critical quality attributes for a pharmaceutical product can help to:  

  • Ensure products meet defined critical quality attributes 

  • Meet regulatory compliance criteria 

  • Predict formula robustness 

  • Reduce waste in production 

  • Get to market faster 

Using DOE to Optimize Processes

When it comes to creating an optimal manufacturing process that limits variation and conserves energy or resources, or a developing a new formula that is most likely to meet customer expectations, design of experiments (DOE) is an indispensable tool. 

DOE helps you to: 

  • Minimize the number of experiments you have to do to find the ideal formula or recipe 

  • Create a robust process (one that holds up to changes in environment, humidity, ingredient variation, etc.) 

  • Adapt a recipe for changes in ingredients or packaging needs (availability, eco-compliance, regulations, consumer trends, etc.) 

What’s the Alternative? DOE vs. Alternative Approaches 

The typical alternative to using DOE to determine which processes or formulas are contenders is the classic “COST” approach.  The COST approach, which stands for “Change One Separate factor at a Time” is a logical way to approach an experimentation, but it requires a lot of time and effort, and may lead to the wrong conclusions.  

COST doesn’t let you consider the interaction between investigated factors and may give you different results depending on your starting point. DOE helps shorten that process and uses advanced data analytics to help inform your decisions about which factors need to be tested.  

Another weakness of the COST approach is that it can’t define the number of runs that will be needed to find the maximum. You can only test two factors at a time and can’t define how many runs you’ll need to be sure you’ve covered all the options. 

Why using DOE is better than using a COST approach: 

  1. DOE suggests the correct number of runs needed (often fewer than used by the COST approach) 
  2. DOE provides an unbiased model for the direction to follow that is independent of start settings 
  3. Many factors can be used (not just two) and their interactions taken into account 

Using DOE to Predict Formula Robustness

Being able to demonstrate product robustness and deliver the intended quality of the product within allowable ranges for the claimed shelf-life period is critical for pharmaceutical manufacturers. Both international and country specific regulatory agencies, such as the FDA, pay close attention to shelf-life claims. 

Predicting formulation robustness requires a careful design of experiments that holds up under statistical analysis. Using DOE for formulation robustness studies can help you select a commercial formulation that is sufficiently robust within the acceptable ranges around the label claim to meet the shelf life stability requirements.

Steps to Predict Formula Robustness

Step 1: Choose the Right Measurement Factors  

Ensure that the factors selected to study can be used to predict an acceptable formulation parameter range where all the values for the assessed quality attributes will be inside the specified limits. 

Step 2: Design a Statistically Valid Study 

Consider how the factors being investigated fit into a full factorial design. For pharma companies, for example, robustness studies must be able to prove that specific critical quality attributes stay within the acceptable ranges for the entire shelf-life period. In addition: 

  • The study must result in a regression model that is statistically significant 

  • The study must provide output parameters (quality attributes) that are within predefined limits 

Step 3. Analyze the Data Using Multiple Linear Regression 

One important way to produce a valid testing model is to use a tool that makes Design of Experiments easier. For example, MODDE® Design of Experiments Software, can help you set up multivariate formulation robustness studies that demonstrate the acceptable ranges of quality for a target composition, define the allowable edges of the composition range, and predict the stability requirements needed to reach the end of shelf life.

Finding the Optimal Design Space

Scientific investigations involve changing a number of controlled variables to direct the response in question towards a desired level. Design of Experiments (DOE) is a rational and cost-effective approach to practical experimentation that allows the effect of variables to be assessed using only the minimum of resources. DOE is the backbone for efficient QbD implementation strategies. The final specifications for a region where all specifications are fulfilled to a defined risk level is called Design Space. Determining the optimal Design Space is a key advantage of using MODDE® DOE Software.
