Clinical Trial Retention Crisis: 30% Dropout Rate Costs Industry Billions and Delays Drug Development

6 years ago3 min read

Key Insights

  • Global clinical trials face a critical challenge with 30% average dropout rates, while less than 5% of eligible participants initially enroll, significantly impacting drug development timelines and costs.

  • Clinical trial complexity has increased over the past decade, with more frequent visits and data collection requirements, while rare disease focus has narrowed the eligible patient pool.

  • Removing logistical barriers and providing comprehensive patient support services could significantly improve retention rates, according to Greenphire CEO Jim Murphy.

The pharmaceutical industry is grappling with a severe clinical trial retention crisis that threatens the efficiency of drug development and impacts healthcare advancement. With clinical trial costs reaching $35,000 to $40,000 per patient, the industry faces significant challenges as approximately 85% of studies struggle to enroll or retain sufficient participants.

The Scale of the Retention Challenge

The current landscape presents a stark reality: less than 5% of eligible participants join clinical trials, and of those who do participate, roughly 30% drop out before completion. This attrition rate creates substantial delays in drug development and drives up research costs, ultimately affecting healthcare accessibility and drug pricing.
"Drug prices are high, and it's no mystery why when it's so expensive to get a treatment approved. But if we can keep patients in the trials, we can have statistically significant data more quickly," explains Jim Murphy, CEO of Greenphire, a clinical trial payment software company.

Evolving Trial Complexity

Over the past decade, two significant trends have exacerbated retention challenges:
  1. Increased data collection requirements leading to more frequent and longer site visits
  2. A shift toward rare disease treatments and targeted therapies, which has narrowed the eligible patient pool
These changes have created a situation where participants often travel greater distances to trial sites, adding to the burden of participation. "Longer, more frequent visits place a greater physical burden on the patient, and all the time more and more trials are looking for candidates who are like a needle in a haystack," Murphy notes.

Impact on Site Operations and Patient Experience

Site staff increasingly find themselves managing complex logistics rather than focusing on patient care. This administrative burden affects the quality of patient relationships, which are crucial for retention. "If a patient feels they are valued and they have a personal relationship with the site staff, their retention likelihood is much higher," Murphy emphasizes.

Solutions for Improving Retention

The industry is actively exploring solutions to address these challenges. Key approaches include:
  • Immediate reimbursement for patient expenses
  • Comprehensive travel coordination across multiple countries
  • Streamlined administrative processes
  • Enhanced support services for patients and caregivers
"We can't control protocol – protocol is what it is – but if you can take care of all those other elements of patient convenience in a way that actually reduces the burden on the investigative site, you've added connectivity and allowed more time for the site to focus on the patient," Murphy explains.

The Future of Clinical Trial Management

Digital health and medical technology innovations are opening new possibilities for improving trial efficiency. These advancements could help transform the traditionally lengthy and inefficient clinical trial process into a more streamlined experience for all stakeholders.
The industry's focus on removing logistical barriers represents a crucial step toward improving retention rates and accelerating the development of new treatments. As Murphy concludes, "There are a lot of great ideas out there, there's an incredible boom of treatment innovation and that's really exciting. It is challenging us to evolve the clinical trial process so that it is better for everyone: the site, the patient and the sponsor."
