Cytel data scientists apply advanced statistical techniques including predictive modeling of biological processes and drug interactions to unlock the potential of big data. Our team supports biomarker discovery and diagnostic test development based on biomedical signals and images, and real world evidence analysis.

Exposure (and Dose) Response Analyses, including pharmacokinetic and pharmacodynamics analyses, guide critical decisions in drug development. Cytel’s expert Quantitative Pharmacology and Pharmacometrics group delivers high quality solutions to help our customers get those decisions right.

Cytel has a strong track record in providing CDISC solutions and we are a CDISC Registered Solutions Provider. We have converted more than 150 studies as part of NDA submissions, all of which have been accepted by the FDA. The Clinical Data Interchange Standards Consortium (CDISC) devised the SDTM and ADaM models to standardize data structures for submission of raw and analysis data from clinical trials. These standard formats are increasingly expected by regulatory authorities including the FDA.

Extensive time and energy is often spent designing feasible clinical studies. East's broad range of statistical tools and expert simulations provides an invaluable resource for the rapid construction of trial designs. Illuminating graphs and charts allow for accessible comparison, while a user-friendly interface encourages exploration and experiment.

EnForeSys is a user-friendly decision tool that leverages simulation methods to predict recruitment milestones with high accuracy. Armed with a reliable probability of success, you can rest assured that your trial will reach its targeted enrollment on time and on budget.

We believe that expert statistical input has the power to shape the future of clinical development: de-risking portfolios, accelerating timelines, and increasing the probability of success.

  • Clinical Development Challenge - Use Of RWA To Understand Natural History

    A biotechnology company without an in-house real-world evidence team did not have the adequate resources, connections, or expertise available to conduct a natural history study of the rare, oncology indication for which they were developing a new therapy. Their solution was found in a virtual real-world evidence department.

  • Bayesian Methods For Contending With Homogeneity And Heterogeneity In Real World Data

    Over the past decade, single arm trials have increasingly become an accepted way of assessing a new treatment intervention. These trials make use of synthetic control arms (SCAs) and real-world data or historical clinical trial data. Learn what situations are best suited for SCAs and how homogenous and heterogenous patient populations can impact the trial.

  • Ensuring An Unbiased Comparator Arm In Clinical Development

    Regulators in the U.S. and Europe have issued a positive response to the use of synthetic control arms (SCAs) in clinical development. The desire for faster and less expensive clinical trials, coupled with the availability of real-world data, were prominent factors. Learn how to avoid sampling bias when using real-world data in conjunction with SCAs.

  • Are You Harnessing The Power Of Your Clinical Data?

    In clinical development, we all strive to deliver therapies that improve patients’ lives. However, the clinical data we generate can profoundly impact our success in achieving this goal. However, generating high-quality clinical data is far from straightforward, especially if you don’t have the appropriate in-house expertise. In this eBook, we discuss what is involved in planning a clinical data strategy for the entire duration of a development program, as well as for Phase 1 and Phase 2 trials specifically. We also outline some best practices for planning your data strategy, including tips from Cytel experts working in our Strategic Consulting, Clinical Research Services and Data Management teams.
