Data Engineering for Research Unit

VHIO Biostatics unit team members

VHIO’s statistics unit implements innovative biostatistical methodologies to optimise study design, clinical-molecular data analysis and its subsequent interpretation to enhance its clinical and pre-clinical research.

The unit collaborates with the different research groups, both in clinical trials and observational studies, throughout the project life cycle: from study design and methodology to statistical analysis, graphic representation and publication of the study. Areas of work include sample size calculation, complex analyses with survival endpoints and competitive risks, multi-state models and the conduct of systematic reviews and meta-analyses.

In recent years, the Biostatistics Unit has worked on the design and subsequent publication of the results of various phase I, II and III studies led by VHIO researchers. It has also worked on the validation of new biomarkers created by the institution in clinical and pre-clinical contexts.

Some of the short-term strategic objectives include: i) facilitating the design and execution of more VHIO researcher-led studies; ii) implementing new adaptive designs in phase I/II studies; iii) maximising the value of real-world data to generate new evidence outside the context of clinical trials; and iv) validating the prognostic and predictive value of new tests and biomarkers.

The unit also collaborates on European and Spanish projects dedicated to the creation and implementation of new statistical designs. It does so with a view to enhancing new designs in dose-escalation studies aimed at maximising the likelihood of selecting the optimal dose level for the subsequent development of the drug. It also seeks to evaluate the real potential of using synthetic controls as comparative groups in single-arm trials.

Head of Unit
  • Designing phase I-II and phase II-III trials to accelerate the evaluation of the efficacy and safety of new treatments.
  • Implementing adaptive designs in dose-escalation studies aimed at maximising the likelihood of selecting the optimal dose level for the subsequent development of the drug.
  • Building prognostic and predictive models for the validation of biomarkers in oncology.
  • Conducting systematic reviews and meta-analyses in cancer research settings where questions remain unanswered.
  • Producing multi-state models, survival analyses and competitive risk assessments.
  • Enhancing the efficacy of using synthetic controls as comparative groups in single-arm trials.
  • Establishing an automated data processing, statistical analysis and results reporting structure in the different clinical and pre-clinical research projects carried out at VHIO.
