Use Cases

Decentralised Clinical Trials (DCT)

A shared infrastructure for optimising clinical trials. Public health researchers are choosing to switch from standard face-to-face data collection methods to remote data collection in support of continued research.


Collecting trusted, verifiable data directly from patients: authenticated, traceable, audit proof, based on consent. Re-use of data improves effectiveness of clinical trials programs.

Data management challenges

Decentralized clinical trials (DCTs) are designed to address several challenges and limitations associated with traditional, site-based clinical trials. These trials enhance patient recruitment and retention by leveraging technology to enable remote participation, eliminating geographical constraints and frequent in-person visits.

Today’s web2.0 infrastructure is not fit-for-the-purpose, lacking the necessary security, privacy, and hence efficiency for regulated digital interactions.


Web3.0 is the decentralised internet that enables a new portable ‘verifiable persona’ of humans and ‘things’ to digitally interoperate freely and without discrimination.

Verifiable credentials are issued to the respective patients’ or customers’ digital wallet. Authenticity can now be confirmed without need to contact issuer.

Privacy-enhancing technologies bring value to the entire clinical trial process. They improve onboarding, authentication, consent, and the collection of verified clinical data. The KATLAS health wallet gives individuals control over their digital experiences in health, work, and life.

By connecting these experiences on a secure network that doesn’t rely on ‘trusted’ third parties and respects privacy and ownership rights, clinicians can gain valuable insights about people, places, and things to offer more personalized solutions.


  1. DCTs improve geographic accessibility, particularly for patients in rural or underserved areas, by allowing them to participate from their homes, expanding the potential participant pool and promoting diversity in trials.
  2. They excel in real-world data integration, collecting data in natural environments to complement controlled trial data.
  3. DCTs address patient diversity issues by reaching a broader, more representative group of participants. Additionally, they enhance data quality and accuracy through digital tools and electronic health records, reducing errors.
  4. Cost efficiency is another advantage, as DCTs eliminate physical trial sites, reduce monitoring visits, and streamline data collection, potentially lowering overall trial costs.
  5. DCTs often execute trials more efficiently, expediting trial completion while prioritizing the patient experience, offering flexibility, and maintaining scientific rigor.
  6. Furthermore, they incorporate safety and adherence monitoring tools, ensuring real-time tracking for patient safety and protocol adherence, ultimately enhancing data quality and patient safety in these innovative trials.

Functional Features of the Health Wallet System

KATLAS Web3.0 as-a-service represents a shared digital infrastructure. our Health Wallet System offers a customer-centric solution that empowers SMEs to transition from managed services to personalized, direct relationships with their customers.

Privacy by Design: Quantum resistant standards allow for secure data handling, sensitive data does not leave jurisdictions without consent, and data may be deleted at the discretion of the owner.

Universal Interoperability: A platform agnostic design ensures compatibility with existing infrastructure with standard interfaces facilitate seamless integration.

Genuine Scalability: Local or cloud computation power may be employed that is fit for purpose in coordinating billions of nodes with efficient allocation of data availability in the network.

Incremental Extensibility: A data agnostic approach conforms with the diversity of data in health: from meta data to multi-omics like genomes. Further capabilities may be added leveraging agility.

Stakeholder Empowerment under appropriate Regulation: Role-to-role protocols model the relations of stakeholders among another, twinning their real-world relationships. Ecosystem twinning allows users to act on their interests.
