The ongoing challenge of clinical trial recruitment: What sponsors must change

Clinical Trial Recruitment

The Sponsor’s Dilemma

Every sponsor has lived through this moment: the trial is funded, sites are activated, protocols approved. On paper, everything is ready to roll. But then the calls start coming in. Enrollment is not moving. Weeks drag on, recruitment targets slip, and suddenly your timelines are at risk.

It is not just frustrating. It is expensive. Industry numbers show that 80–90% of trials miss enrollment timelines, and each day of delay can burn anywhere from $600,000 to $8 million in lost opportunity, depending on the therapy area. According to the Tufts Center for the Study of Drug Development, recruitment delays remain one of the costliest problems sponsors face.

So why is recruitment still stuck, even in 2025 when we have more digital tools and patient data than ever before?

Why Recruitment Remains a Challenge

Protocols That Work Against You

Inclusion and exclusion criteria keep getting tighter. Protocols demand more data points. That means fewer people qualify, and the ones who do may not stay once they see how heavy the commitment is. The FDA’s guidance on eligibility criteria highlights this ongoing challenge.

Sites Cannot Do It Alone

Sites remain the backbone of recruitment, but they are stretched thin. Coordinators balance protocol compliance, data entry, and participant care. Recruitment is often just one more responsibility. Without digital support, their reach is limited to who walks through the clinic door.

Patients Still Struggle to Find Trials

Think about how patients actually discover trials. They bounce between registries, advocacy sites, and sponsor pages. The process is confusing, overwhelming, and in many cases discouraging. If patients cannot easily understand where they fit, they will not enroll. The largest public resource, ClinicalTrials.gov, is comprehensive but difficult for most patients to navigate, which is why platforms like our Find Clinical Trials Near Me tool exist.

The Burden Is Too High

For participants, long questionnaires, frequent visits, and rigid schedules feel like signing up for a second job. Meanwhile, their everyday healthcare has shifted to apps, telehealth, and home delivery. If trials do not match that level of convenience, people walk away. 

Sponsors React Instead of Plan

Most recruitment plans get serious only once a trial is live. By then, you are already on the back foot. It becomes a reactive scramble, not a strategy, and the delay is built in from the start.

What Sponsors Can Do Differently

Recruitment does not have to feel like quicksand. The sponsors who are getting ahead are reframing it: not as a one-time hurdle but as a continuous engagement strategy.

1. Put the Patient Lens First

Ask a different question: not “How do we fill this trial?” but “What would make someone want to join and stay?” That shift drives simpler entry points, clearer consent, and stronger trust.

2. Use Digital Pre-Screening

Pre-screening tools can filter thousands of potential participants in days, not months. They cut site workload and prevent wasted time on ineligible candidates.

3. Go Beyond Geography

Hybrid and decentralized approaches mean patients do not have to live near a site to take part. Remote pre-screening, e-consent, and virtual follow-ups remove barriers and broaden your pool. 

4. Close the Gap With Real-Time Matching

Matching algorithms can connect participants to active trials instantly, not weeks later. That shortens the window where interest fades and dropout risk climbs. Explore our Trial Matching feature.

5. Lean on Advocacy and Community Groups

Patients trust advocacy organizations more than sponsor ads. Partnering with these groups builds credibility and expands reach, especially with underserved or diverse populations.

6. Cut the Friction

Mobile-friendly forms, flexible scheduling, and remote data collection are no longer optional. They are what participants expect. Make it easy, and retention improves.

From Recruitment to Engagement

Here is the bigger point: recruitment is not just about hitting enrollment numbers. It is about building relationships. Participants are not data points. They are people making a commitment to advance science.

Sponsors who treat recruitment as engagement win on three fronts:

  • Participants feel informed and respected.
  • Sites are not stuck chasing leads that go nowhere.
  • Sponsors save both time and money.

That is a strategy built for the future.

The DecenTrialz Approach

At DecenTrialz, we have built our platform around this exact idea. Our focus is on making recruitment faster, smarter, and more participant-friendly.

With HIPAA-compliant pre-screening, real-time matching, and a referral process that respects both patients and sites, sponsors get:

  • Quicker turnaround from interest to enrollment.
  • Trust built in at every step.
