Enforesys
Enrollment forecasting and trial operations optimization for clinical trial implementation.
Overview
Enforesys is a purpose-built clinical trial implementation software developed by Cytel, designed to help pharmaceutical and life sciences teams forecast enrollment reliably and optimize trial operations. By leveraging Monte Carlo Simulation, Enforesys delivers accurate enrollment probability forecasts, automates simulation tasks, and presents results in an easily interpretable format — empowering clinical trial teams to anticipate recruitment challenges and execute trials on time.
The software is widely adopted across the pharmaceutical industry and addresses the full range of enrollment forecasting challenges, including uncertain recruitment rates, variability in patient populations, site performance issues, protocol amendments, competing trials, and regulatory delays. Enforesys provides realistic expectations and enables proactive risk-mitigation planning throughout the trial lifecycle.
Core Forecasting Capabilities
- Monte Carlo Simulation engine: Generates accurate enrollment probability forecasts by running large-scale simulations that account for the inherent variability and uncertainty in clinical trial recruitment.
- Data-driven predictions: Utilizes historical site-level data and other elements proven to affect enrollment to produce reliable predictions of enrollment milestones.
- Single- and multi-cohort trial support: Capable of forecasting enrollment across both single-cohort and multi-cohort trial designs, accommodating a wide range of study structures.
- Automated simulation tasks: Reduces manual effort by automating the simulation workflow, allowing teams to focus on interpreting results and making informed decisions.
Strategic and Operational Benefits
- Enhanced strategic insights: Enables teams to evaluate and select the best strategy for available resources, flag potential enrollment challenges early, and chart a clear path to a successful trial.
- Risk-mitigation planning: Provides the foresight needed to develop and implement proactive risk-mitigation plans before enrollment challenges escalate.
- Informed decision-making: Delivers realistic enrollment expectations that support evidence-based decisions at every stage of trial implementation.
- Operational efficiency: Streamlines trial implementation by integrating enrollment forecasting into broader trial management workflows, helping ensure timely trial execution.
