“What does the patient need?”

It’s a question José Ajenjo comes back to time and again.

Not what has always been done. Not what’s easiest for the research team. But what will genuinely make clinical research more accessible, more inclusive, and more meaningful for the people it’s designed to help.

That way of thinking has shaped José’s career across clinical operations, innovation, patient recruitment, and diversity initiatives. Whether he’s exploring new technologies, reimagining patient recruitment, or advocating for greater equity in research participation, one principle remains constant: clinical research should adapt to patients—not the other way around.

It’s a philosophy rooted in curiosity, strengthened by personal experience, and driven by a simple question he still asks every day:

“Why not?”

A Journey Fueled by Curiosity

José’s path into clinical research wasn’t something he planned from the beginning.

He studied Veterinary Medicine at the University of León, where he joined the Department of Surgery and worked closely with the Health Research Foundation of León. During his doctoral research, which focused on the cardiac characterization of an animal model for preclinical research, he encountered clinical trials for the first time.

“My journey into clinical research was a natural evolution rather than a planned destination,” he says. “I was immediately fascinated by the potential they held.”

That fascination inspired him to pursue a Master’s in Clinical Trial Management and Monitoring. From there, his career evolved into one focused on improving how clinical research is designed, delivered, and experienced by patients.

Innovation Begins with Equity

Throughout his career, José has worked across clinical operations, innovation, and patient recruitment. While each role has brought different responsibilities, they’ve all been guided by the same purpose.

“What drives me most is the opportunity to contribute to the development of new therapies that genuinely help patients — and to help accelerate that process.”

He is equally passionate about positioning Spain as a leader in clinical trial innovation and development.

But what makes that mission deeply personal is where he comes from.

“I come from a part of Spain considered a demographic desert — a region with limited access to healthcare and virtually no access to clinical trials. That lived experience fuels my commitment to ensuring that every patient, regardless of their location, background, or circumstances, has a fair and equitable opportunity to participate in clinical research.”

Growing up in a community with limited access to healthcare shaped the way José views clinical development today. For him, diversity, equity, and inclusion aren’t simply initiatives—they’re essential to ensuring that every patient has the opportunity to benefit from research.

“Equity, equality, and justice in clinical development are not just professional goals for me — they are deeply personal ones.”

Starting with the Patient

Innovation is often associated with technology.

José sees it differently.

“The biggest challenge — and the greatest learning — has been learning to think outside the box. It’s not about what we do or what others do. It’s about asking: What does the patient need? Where is that patient? And what can we do to make participation as accessible and comfortable as possible for everyone?”

That perspective influences every challenge he takes on.

Rather than expecting patients to navigate complex research systems, José believes clinical research should remove the barriers that make participation difficult. Whether those barriers involve geography, race, ethnicity, religion, gender, language, or other circumstances, his goal remains the same: make research accessible to everyone who could benefit from it.

He also believes meaningful change goes far beyond introducing new tools.

“Driving this kind of change requires not only an internal cultural shift within the company, but also regulatory, professional, and societal transformation — always with the patient at the centre, and ideally, developed with the patient.”

Rethinking How Research Reaches Patients

When asked what innovation has made the biggest difference in helping patients connect with clinical trials, José doesn’t hesitate.

“Without a doubt, the decentralisation of clinical trials — dramatically accelerated during the COVID-19 pandemic — has been one of the most transformative shifts. It forced the adoption of new technologies and fundamentally challenged the traditional hospital-centric model of clinical research, bringing the trial to the patient rather than the other way around. That paradigm shift has had a lasting and profound impact on accessibility and patient engagement. “

For decades, participation often depended on patients traveling to research sites.

Decentralized clinical trials challenged that model by bringing research closer to patients, making participation possible for people who previously may have been excluded because of where they lived or the burden of travel.

For José, that shift represents much more than technological progress. It’s an important step toward making clinical research more accessible, inclusive, and patient-centered.

Looking Ahead Through Better Data

Another development that excites José is the growing potential of health data to improve clinical research across Europe.

“This one is very clear to me: the new regulatory framework around health data spaces, particularly the European Health Data Space (EHDS) and its applicability across EU member states.”

He believes initiatives like the EHDS create opportunities to use real-world data to make clinical trials faster, safer, and more efficient while bringing real-world evidence closer to clinical development.

Just as importantly, he sees the potential to reduce geographic, gender, ethnic, and racial bias in patient identification, helping future clinical trials become more representative of the communities they aim to serve.

When Research Becomes Personal

Working in clinical research means witnessing many moments of hope.

José has experienced that while supporting therapies for rare diseases, watching patient communities celebrate the possibility of new treatment options.

“There are many, especially when you work on therapies for rare diseases and witness the enthusiasm and hope of patient associations when new treatment options emerge. But the most personal moment for me was seeing members of my own family benefit from a treatment that I had contributed to developing.”

For José, that experience transformed years of work into something deeply personal.

“Being able to witness, firsthand, the real-world impact of your work on people you love — that is something that stays with you forever and reminds you exactly why this work matters.”

It’s a reminder that behind every protocol, innovation, and clinical trial is a person hoping for a better future.

Never Stop Asking “Why Not?”

José approaches challenges with the mindset of someone who believes there is always another possibility worth exploring.

When asked which fictional character best reflects his approach to clinical research, his answer comes quickly.

“Iron Man.”

Not because of the technology or the armour.

“The relentless drive to innovate, to build something that doesn’t yet exist, to constantly improve and push beyond what’s already been done. Tony Stark never settles for a final version; he’s always looking for the next iteration, the next possibility. That’s exactly how I approach clinical research: never satisfied with the status quo, always asking what more we can do.”

That same mindset is reflected in the question that continues to inspire him.

“It’s not a quote — it’s a question I ask constantly: ‘Why not?’ Why can’t we do this? Why can’t we try this?”

For José, challenging convention isn’t about change for its own sake. It’s about creating better possibilities for patients.

Beyond Research

Outside of work, José enjoys music that reflects the same energy he brings to innovation.

“Rock — and more specifically, punk rock and heavy metal. There’s something about the energy, the rebellion, and the refusal to accept limits that resonates with how I approach my work.”

He is also a proud supporter of CD Numancia, the football club from his hometown.

“It’s more than football — it’s identity, roots, and community.”

And if he could invite one fictional character to join his team?

His choice is Harvey Specter from Suits.

“His ability to face seemingly impossible problems with composure, strategic thinking, and an unshakeable belief that there is always a way forward — that’s exactly the mindset you need when navigating the complexities of clinical research. He doesn’t accept ‘it can’t be done.’ Neither do I.”

Challenging What’s Possible

As José reflects on his journey, one message rises above everything else.

“Clinical research is one of the most meaningful fields you can work in — because every decision, every innovation, every barrier we remove has a direct impact on a real person’s life.”

His advice to the clinical research community is very simple.

“Keep the patient at the centre of everything you do, dare to ask ‘why not?’, and never underestimate the power of diversity — in patients, in teams, and in ideas. Together, we can make clinical research more accessible, more equitable, and more impactful for everyone.”

It’s a philosophy that has guided José from a veterinary student discovering clinical trials for the first time to a leader helping shape innovation in clinical research today.
