  1. DOE Reduces Bioequivalent Generic Development Time to 4 Months

    July 2016

    A generic pharmaceutical manufacturer recently hired VerGo Pharma Research Laboratories Pvt. Ltd to develop a bioequivalent with different polymorphic forms for an anti-depressant drug that had previously been patented in crystalline form only. Bioequivalence requires that a drug be pharmaceutically equivalent and that it be delivered at the same rate and same level of bioavailability so that its efficacy and safety can be expected to be the same as the original product. By using design of experiments (DOE) to reduce the number of tests required (to determine the effects of inactive ingredients on bioavailability in both fed and fasting conditions), VerGo was able to cut the development process from several years to only four months.

    A variation of this case study was also printed in R&D magazine, July 2016, as Scientists Develop Bioequivalent Drug in Months instead of Years.

  2. How To Get More Learning With Less Experimentation

    January 2016
    Experimentation informs every part of the biologic lifecycle. But it is costly and time consuming — especially when you are using outdated methods. As you strive for more efficiency from your scientists and engineers, can you streamline your work processes to get more learning with less experimentation? Both multivariate analysis (MVA) and design of experiments (DoE) methods have numerous applications for simplifying the learning from large data sets and experimentation. However, many scientists and engineers still perceive these methods to be complex. Today’s newer, intuitive software applications make these techniques user-friendly for even non-statisticians. Early adopters are seeing decreased time to market, reduced development and production costs, and improved quality and reliability.

  3. Conquer Pilot Plant Challenges

    November 2015
    A pilot plant usually plays a key role in process development by providing essential data related to operation, safety, scale-up and other issues. The value of the pilot plant depends on the validity of the data captured. Planned experimentation is crucial to gathering meaningful data, and design of experiments (DOE) is the gold standard for finding results which are statistically significant.

  4. Design of Experiments Validates Corn Ethanol Measurement Technology

    June 2014
    An industrial equipment supplier wanted to find the best operating conditions, as well as determine what performance its product could deliver for ethanol producers, before putting the device on the market. A DOE was run to successfully identify and validate a measurement method that has enabled the supplier to accurately evaluate the performance of the new product in a large number of plants under a wide range of operating conditions.

  14. Application of Design of Experiment (DOE) Techniques to Process Validation in Medical Device Manufacture

    February 2006

    This paper provides an overview of the application of DOE techniques during key aspects of process validation and discusses two practical examples from medical device manufacturing. The attendant benefits of this type of procedural approach to the medical device sector are considered. From the results obtained, it is clear that meeting process validation requirements can be taken as an opportunity to better understand and improve manufacturing processes. As such, DOE techniques are pivotal in effectively achieving these aims in a manner that provides for regulatory compliance.
