One hand doesn’t know what the other is doing: Finding clinical trials designed WITH patients

This Talk Clinical Trials blog has been written by Professor Karen Woolley. Karen is a bereaved parent, clinical trial participant, caregiver, and advocate for greater involvement of patients in medical research, including trial design and publication.


If you are reading this blog, you could help improve access to clinical trials.  You could lend a hand to help patients find clinical trials designed WITH patients. This matters. One day, you or someone you know may desperately want to find these patient-focused trials.

It certainly isn’t easy to do now, but you could help make it much easier for yourself and others in the future.

What’s the problem?

There is increasing evidence1-6 that clinical trials designed WITH patients are better—better for patients, site staff, researchers, and funders:

  • Fewer participant burdens
  • Faster recruitment
  • Higher retention
  • Improved data quality
  • Lower costs
  • Faster timelines

One hand is working hard to make clinical trials easier for patients by designing them WITH patients. That’s the good news.

The bad news is that the other hand isn’t making it easier. You simply can’t find trials designed WITH patients by searching clinical trial registries.

Trust me, we tried. And tried. And tried. All to no avail.

Our family was facing yet another life-threatening cancer diagnosis and we were desperate to find clinical trials designed WITH patients.

We searched every clinical trial registry on the WHO registry network and every registry from the world’s top 10 pharmaceutical companies. Nothing. All other things being equal, why wouldn’t you want to find trials designed WITH patients? Why wouldn’t you want to enter or recommend a trial that was likely to be better for all concerned?

Our family wrote a peer-reviewed publication7 and made a podcast8 to raise awareness of this problem. Both are free to access.

What’s the solution?

We already have clinical trial registries to help people find relevant trials. Rather than creating an entirely new system, all we need is two targeted changes:

  1. Add a search filter for patient involvement
    Clinical trial registries already include numerous search filters. Adding just one more that identifies trials designed WITH patients would be a practical and achievable enhancement.
  2. Add plain language information about HOW patients were involved.

    With more pressure from funders, publishers, journal editors, and ethics committees to be transparent about patient involvement in trial design, sponsors will already have to document this information. They could readily automate the re-use and uploading of this information to clinical trial registries.

    We know clinical trial registries were designed to help patients find trials, and we know that patients are regular users of clinical trial registries. Surely it is time to help patients find trials designed WITH patients.

What do others think?

When I asked leading patient advocates around the world and their allies whether patients should be able to find clinical trials designed WITH them, they gave a resounding ‘YES!’

  • “Patients should be able to look at any clinical trial registry and immediately understand which studies were shaped by patient involvement. Making this visible is not just a matter of transparency—it’s a matter of respect and equity. When patients’ voices are part of trial design, outcomes become more meaningful, and participation becomes more accessible.” — Dr Amy Price: Patient Advocate; Editor-in-Chief (Journal of Participatory Medicine)
  • “When a clinical trial acknowledges the voices, priorities, and realities of the people it hopes to serve, everything improves, from trust to understanding and ultimately participation. A simple field or filter that highlights patient involvement in trial design would give people genuine agency in their search for options. It would also signal, in a very practical way, that their experience matters.” — Keith Berelowtiz: Ethics Committee Chair; Founder, trialport and pRxEngage
  • “From a perspective of an early phase clinical trials investigator in solid tumours, I believe there is a greater need for patient/consumer engagement and consultation in clinical trial design and protocol development… having filters to retrieve trials designed with patient involvement would be critical.” — A/Professor Jia Jenny Liu: Medical Oncologist; Clinical Trials Investigator
  • “Documenting patient involvement in the design of cancer trials enhances the process by ensuring that safety, operational efficiency, and efficacy are considered from a multi-stakeholder perspective. Public reporting of engagement practices will incentivise sponsors to adopt a more collaborative approach to trial design, reinforcing the critical role of patient partnerships in trial optimisation.” — Dr Frank Lin: Medical Oncologist; Deputy Editor (JCO Clinical Cancer Informatics)

Where to go from here?

One path forward is through existing clinical trial registry systems. The World Health Organization International Clinical Trials Registry Platform has kindly reviewed our family’s publication and may consider whether patient involvement could be included as an optional registry data field. The complexities of change in large organisations are not to be under-estimated, but there is reason here for cautious hope. Hope, coupled with advocacy, can be powerful.

Other options include piloting a patient involvement filter and a plain-language field describing how patients contributed to trial design. This could be done in an existing registry and results of the pilot study could be published. A successful case study could also expedite change.

What could you do?

As someone interested in clinical trials, I hope you can share this blog, as well as our family’s publication and podcast, with others in your network.

Raising awareness of the gap in clinical trial registries is a key first step. As word spreads, a ‘coalition of the willing’ might form to help take this patient-first initiative forward. All hands on deck, as it were!
