Singapore's biotech hub, centered around hubs like Biopolis, is at the forefront of global medical innovation. Powering this groundbreaking research is high-quality clinical data, often collected directly from trial participants through surveys and Patient-Reported Outcome (PRO) instruments.

But this data is the most sensitive personal information imaginable, and its collection is governed by a multi-layered framework of legal and ethical regulations. For Clinical Research Organizations (CROs), biotech startups, and academic researchers, navigating this landscape is a paramount responsibility.

This guide provides a framework for designing and conducting digital clinical trial surveys, ensuring you meet Singapore's rigorous compliance standards while leveraging the efficiency of modern data collection tools.

The Three Pillars of Compliance for Health Research Data in Singapore

Your data collection strategy must be built on three foundational pillars:

1. The Personal Data Protection Act (PDPA): This is the baseline privacy law.1 All participant data is personal data, and health information is classified as sensitive, requiring a higher standard of protection. Key obligations include consent, security (Protection Obligation), and strict rules on cross-border data transfers (Transfer Limitation Obligation).2

2. The Human Biomedical Research Act (HBRA): This act provides a specific legal framework for the conduct of human biomedical research in Singapore. It establishes the mandatory requirement for obtaining informed consent from research participants and requires that most research is overseen by an Institutional Review Board.

3. Institutional Review Board (IRB) Approval: No clinical research can begin without the approval of a certified IRB (also known as a Research Ethics Committee). The IRB will meticulously scrutinize your entire research protocol, including your data collection methods, consent forms, participant privacy protections, and data security measures.

A Checklist for Your IRB-Ready Clinical Trial Survey

✓ 1. Design for True "Informed Consent"

This is more than just a simple checkbox. Informed consent is a process.

• The Rule: Under the HBRA, participants must be given comprehensive information about the study's purpose, procedures, potential risks and benefits, and their right to withdraw at any time, all in a way they can understand.

• The Action: Your digital form must facilitate this. Use a multi-page Walla Form to break down the complex Patient Information Sheet and Consent Form (PICF). Use clear headings, simple language, and include mandatory, unchecked checkboxes for each key consent statement (e.g., I consent to my data being used for this study, I understand I can withdraw at any time).

✓ 2. Architect for Data Minimization and Pseudonymization

To minimize risk, you should separate a participant's direct personal identifiers (name, NRIC number, contact info) from their clinical data wherever possible.

• The Action: Design your data collection workflow to assign a unique, non-identifiable Participant ID to each respondent upon consent. Use this ID as the primary key for your research dataset. Walla Form can be used to securely collect the initial identifiable data for consent and then link it to a separate, pseudonymized form for the actual clinical survey data.

✓ 3. Implement "Fortress-Grade" Security

The PDPA's Protection Obligation is amplified for sensitive health data. Your platform's security must be uncompromising.

• The Action: Your data collection platform must provide:

  • End-to-end encryption for all data, always.

  • Granular, role-based access controls (RBAC) to ensure only authorized research personnel can access specific datasets (e.g., a data analyst should only see pseudonymized data).

  • Detailed, immutable audit trails to track every single interaction with the data, which is essential for accountability and IRB review.

✓ 4. Guarantee Data Integrity and Residency

The integrity of your research data is paramount, as is its protection under Singapore law.

• The Rule: The PDPA's Transfer Limitation Obligation creates significant hurdles for storing data outside of Singapore. For sensitive clinical trial data, IRBs and institutions will strongly prefer, if not mandate, that the data remains within Singapore's robust legal jurisdiction.

• The Action (The Walla Solution): The most defensible and trustworthy strategy is to guarantee the data never leaves Singapore. Walla Form’s Singapore data region provides this assurance. It's a simple, powerful way to assure your IRB, your institution, and your participants that their most sensitive data is protected by Singapore's strong legal framework.
