Overview

Clinical Research, a leading clinical research organization operating across multiple regions, faced serious risks caused by duplicate and professional subjects entering multiple studies under different identities. This led to compromised data integrity, regulatory concerns, and delays in study timelines. They also needed reliable Study/Protocol-wise visit tracking and a controlled process ensuring that only trained and certified site users could enter participant data.

To address these challenges, Prime Horizon Technologies delivered two integrated, high-security solutions.

Prime Horizon Technologies engineered CTSdatabase to serve as a centralized clinical trial subject registry. They designed it specifically to detect and prevent duplicate subjects without exposing private or identifiable information.

  • Anonymity by Design: Prime Horizon Technologies ensured the system maintains complete subject anonymity while identifying attempts by professional subjects to alter their presentation.
  • Investigative Insights: They provided investigators with a full history of a subject’s past study participation. They delivered actionable match insights that enable confident enrollment decisions.
  • Access Control: Prime Horizon Technologies enforced site-user training and certification requirements before any subject data can be entered.
Alongside this, Prime Horizon Technologies developed the Clinical Research Data Quality Program. They strengthened oversight of Study/Protocol-wise visit data and automated quality-control workflows. They significantly improved data accuracy and overall operational reliability across sites. Together, these platforms transformed the client’s clinical operations.

Challenges & Solutions

Challenges Faced by the Client

  1. High risk of duplicate and professional subjects enrolling across different clinical trial sites, threatening study integrity.
  2. Need a secure, privacy-preserving identity verification mechanism without collecting or exposing personal information.
  3. Complex multi-step workflows for rater surveillance, quality monitoring, and Study/Protocol-wise visit management.
  4. Lack of real-time insights, making it difficult for site users, sponsors, and analysts to track operational KPIs.
  5. Inconsistent or outdated data across systems, leading to reporting gaps and compliance risks.
  6. Scalability limitations as the number of studies, sponsors, and trial sites continued to grow.
  7. Need to ensure site-user training and certification compliance before allowing any study data entry.

User-friendly Power Apps web interface for site-level and sponsor-level operations

Scalable Azure DataBricks ETL pipelines for scientific, statistical, and operational data processing

Advanced analytical dashboards for real-time decision making and study oversight

Module: Sponsor Portal Dashboard

1. Protocol Violation Monitoring

This visualization offers sponsors immediate insight into why subjects are flagged or disqualified within a selected study. It aggregates specific rule violations to highlight common eligibility breaches, such as washout failures or active enrollment in other trials.
  • Visualizes total flag counts categorized by violation type (e.g., Age/BMI, Active in Another Study).
  • Includes interactive tooltips that display the specific flag name, count, and severity level.
  • Updates the dataset automatically whenever a different study is selected from the dashboard.

2. Cross-Therapeutic Indication Analysis

This visualization provides a breakdown of medical indications associated with matched subjects to track cross-study participation history. It helps sponsors identify if professional subjects are attempting to enroll across conflicting therapeutic areas, such as switching between Schizophrenia and Depression studies.
  • Visualizes the percentage distribution of matched indications (e.g., Schizophrenia, Depression, Migraine).
  • Labels each chart segment clearly with the specific indication name and its calculated percentage.
  • Updates the dataset automatically whenever a different study is selected from the dashboard.

Development Timeline

Prime Horizon Technologies initiated the development of this comprehensive clinical trial ecosystem in June 2023. The project is currently an ongoing engagement, characterized by continuous platform enhancements and the scaling of advanced features through a long-term strategic partnership.

Future Prospects

  • Planned integration with Azure ML: They are building predictive models to identify professional subject behavior.
  • Predictive Analytics: They are developing modules for predictive data quality scoring.
  • Cloud Optimization: They provide ongoing maintenance and cloud cost optimization.
  • Long-term Collaboration: They provide continued enhancements to the platform through an ongoing strategic partnership.
