A Permissioned Blockchain-Based Clinical Trial Service Platform to Improve Trial Data Transparency

Area of Science:

• Clinical research informatics
• Blockchain technology applications
• Data security and privacy

Background:

• Clinical research faces challenges including patient enrollment, data privacy, regulatory compliance, and high costs.
• Current systems often lack transparency and struggle to maintain data integrity throughout the trial lifecycle.
• Public trust in clinical trial outcomes can be undermined by concerns about data manipulation and security.

Purpose of the Study:

• To propose a permissioned blockchain platform for enhancing transparency and security in clinical trials.
• To explore and demonstrate the core functionalities of blockchain technology applied to clinical trial operations.
• To provide a secure and automated solution for managing clinical trial data and processes.

Main Methods:

• Development of a permissioned blockchain platform utilizing smart contracts for automated clinical trial operations.
• Implementation of a web-based user interface for data visualization and network interaction.
• Proof-of-concept demonstration using Hyperledger Fabric for clinical trial management in a multi-trial case study.

Main Results:

• The proposed platform ensures clinical data immutability and transparency, enhancing stakeholder trust.
• Smart contracts automate trial operations, ensuring traceability and preventing data tampering.
• Experimental results validated the efficiency and usability of the blockchain-based platform for clinical trial management.

Conclusions:

• Blockchain technology offers a robust solution to address critical challenges in clinical research.
• The developed platform demonstrates significant potential for improving the security, transparency, and efficiency of clinical trials.
• This approach can foster greater public confidence in the integrity of clinical research processes.
