Blockchain in Clinical Trials: A Game-Changer for Medical Research

Clinical trials are crucial for discovering new treatments for diseases and developing new drugs, therapies, and vaccines. Clinical trials ensure that treatments are safe, effective, and beneficial before reaching patients. However, the current clinical trial process faces significant barriers, such as a lack of trust in the security of sensitive medical information, poor interoperability in digital health records, difficulties in data aggregation, limited incentives for patients to share their medical information, and more. These issues result in serious consequences.

According to the National Institute of Health, 90% of clinical trial development fails due to four major possible reasons – lack of clinical efficacy (40%–50%), unmanageable toxicity (30%), poor drug-like properties (10%–15%), and lack of commercial needs and poor strategic planning (10%).

One such promising yet disruptive technology that has the potential to solve these issues is blockchain. Blockchain healthcare solutions enable the pharmaceutical industry to overcome long-standing clinical trial inefficiencies, reduce costs, and accelerate drug development, ultimately improving global healthcare outcomes. In this blog, we will delve into how blockchain healthcare solutions can radically enhance clinical trials and revolutionize the way information is transacted, stored, and shared.

Understanding Clinical Trials: Phases & Challenges

What Are Clinical Trials?

Clinical trials are structured research studies designed to evaluate new treatments, drugs, and medical devices before public use. Several regulatory bodies across the globe, such as the U.S. Food and Drug Administration (FDA), the European Medicines Agency (EMA), and the Central Drugs Standard Control Organization (CDSCO) in India, oversee these trials to ensure safety and efficacy.

These trials involve multiple stakeholders, including:

• Pharmaceutical companies: Develop and test new drugs.

• Regulatory agencies: Oversee compliance and safety standards.

• Researchers: Conduct and monitor trials.

• Healthcare professionals: Administer drugs and track patient responses.
• Patients: Participate in studies to test treatments.

According to WHO, there are 4 phases of biomedical clinical trials:

Phase 1: Test new drug for the first time on a small group of healthy volunteers to determine a safe dosage range and assess potential side effects.

Phase 2: Testing that has been found to be safe in phase 1 is now tested on a large group of humans to evaluate drug effectiveness and side effects.

Phase 3: Trials are conducted on larger populations in different regions and countries to confirm efficacy, monitor adverse reactions, and compare results with existing treatments.

Phase 4: The study takes place after regulatory approval with the aim to gather long-term safety and efficacy data from a diverse patient population over an extended period. 

Key Challenges in Clinical Trials

1. Complexities in Preclinical Research

Issues like data fabrication, incomplete documentation, and poor reproducibility affect preclinical studies and research integrity. Researchers sometimes manipulate data to achieve desired outcomes which leads to misleading results and wasted resources. Such inefficiencies undermine the credibility of scientific findings and slow down drug development. Implementing a secure, immutable record-keeping system is vital to prevent such issues and strengthen the foundation of clinical trials. 

2. Stringent Regulatory Approval Process for Human Trials

Before starting clinical trials, companies need to file an Investigational New Drug (IND) application with regulatory bodies like the FDA or EMA. This process is time-consuming as it requires extensive documentation, which not only makes the process complex but also increases the cost of drug development. Furthermore, there is a risk of falsified or incomplete data submissions that are done to expedite approvals. There is an urgent need for a solution that can streamline this regulatory approval process in a more secure and ethical way. 

3. Challenges in Patient Recruitment & Consent

Patient recruitment is one of the most challenging and expensive aspects of clinical trials. Many studies fail to meet enrollment targets, which results in delays or even cancellations. Identifying suitable participants while ensuring diversity and compliance adds to the complexity. Although patients sign consent forms, there have been cases of unethical data handling in which patient information is altered or misused. Such challenges in patient recruitment raise serious ethical and regulatory issues.

4. Inefficiencies in Trial Execution & Data Collection 

During the trial, researchers collect and analyze vast amounts of patient data to assess a drug’s effectiveness and side effects. However, centralized data storage systems are vulnerable to hacking, fraud, and unauthorized modifications that compromise the integrity of trial outcomes and potentially impact regulatory approvals and patient safety. Secure data management is crucial to maintaining the integrity of clinical research. Implementing decentralized storage solutions, such as blockchain for clinical trials, can build trust and accelerate the development of safe, effective medical treatments.

5. Data Integrity & Regulatory Submission Issues

Some pharmaceutical companies engage in selective reporting—hiding negative trial results to improve the chances of regulatory approval. This practice compromises patient safety and can lead to the release of ineffective or unsafe drugs. The lack of transparency in clinical trials enables healthcare providers and regulators to make decisions based on incomplete or misleading data that puts public health at risk. Ensuring accountability in clinical trials and implementing strict disclosure policies are vital to maintaining trust in medical research and safeguarding patients from unsafe medications.

6. Limitations in Post-Market Monitoring

Even after a drug receives regulatory approval, monitoring its long-term effects is crucial. However, fragmented data-sharing among researchers, regulators, and healthcare providers creates inefficiencies in identifying and addressing adverse reactions. This lack of coordination can delay critical safety updates. There is a need for a unified, transparent system for real-time data exchange to strengthen pharmacovigilance efforts and enhance overall drug safety in the long run.

Blockchain as a Solution for Clinical Trials

Here’s how blockchain healthcare solutions address the key challenges of clinical trials:
