Confidence Beyond Compliance
PharmaLex is recognized as a global leader in the application of Bayesian methodology consulting and programming in the Biopharma industry, from pre-clinical to late phase studies and in a wide range of therapeutic areas.
Bayesian thinking is at the heart of our approach. While our team is comfortable handling classical or frequentist statistics as well as advanced Bayesian statistics, our problem-solving strategy always puts new problems into a Bayesian perspective. This provides our customers with a crystal-clear understanding of the solutions proposed, its impact and the long term opportunities.
Providing both statistical training and consulting services to pharmaceutical and biopharmaceutical companies, our goal is the same as the companies we support – to efficiently and consistently develop and deliver quality medicine to patients.
PharmaLex has significant expertise in supporting discovery laboratories in pharmaceutical sciences with great emphasis on in-vitro and in-vivo animal models to ensure the studies are adequately reproducible and predictive to support decision making. PharmaLex applies a lifecycle vision and Quality by Design (QbD) approach for in-vitro and in-vivo assays that starts by the definition of the objectives and aims and ends with a control strategy. In between, best practice of Design of Experiments (DoE), advanced modeling and Bayesian statistics are applied to ensure reproducibility and predictability of results.

PharmaLex uses state-of-the-art Artificial Intelligence (AI) and its long experience in data science to solve our specific customer’s problems, as an addition to our strategical statistical services. Our team, composed of experts from various scientific fields such as mathematics, Bayesian statistics, chemistry, bioengineering, etc., is working in close collaboration with our customer to meet their needs. At PharmaLex, we believe a multi-disciplinary team is the best way to make effective data science and support effective decision making in the pharmaceutical world.
Our healthcare expertise combined with our multidisciplinary team are used to deeply understand our customer’s very questions and envisage top-notch AI solution wherever needed. For instance, it is common to apply AI and machine learning tools on big and unstructured data contained in data lakes and other LIMS.
The PharmaLex team masters most advanced programming languages that are used in statistics and Data Science such as SAS, R, STAN, JAGS, Python, Java, C++, but also modern operating environments such as Hadoop or Tensorflow (Keras).
Our key value-added deliverable has always been in delivering fit-for-purpose modeling on which solutions are build. To ensure compliance, our statistical experts are working closely with our IT and Quality departments. It allows for example the creation of AI-powered software, that is completely compliant with regulatory environment (GAMP5, 21CFR part 11). This accumulated sum of competencies makes us one of the few being able to develop solutions in full accordance with all the (Bio-)Pharmaceutical regulation (ICH-USP-EMA). In addition, the software validation ensures that the right diagnostic or answer is provided with high confidence. For validating AI solutions, specific trials are developed to ensure fair comparison with human gold standard or other algorithmic solutions. For instance, our clinical experts can evaluate the impact of modeling/prediction uncertainty directly on the outcome of the clinical study.
As most data scientists, we started applying machine learning methodologies in applied pharmaceutical development (process, assay, etc.) using classical tools such as SVM, Random Forest, Lasso, PLS, etc. We developed predictive methodologies to evaluate model quality as the classical metrics may fail at providing the right conclusion. We stay upfront of the technology by using most recent algorithms such as Boosted Trees or by handling uncertainty in Neural Network (similar to what we do in Bayesian statistics). Computational power for handling big data in short time frame is also available.
