Today, on International Clinical Trials Day, we recognize the people, partnerships, and innovations that continue to shape the future of medicine and improve patients’ lives around the world.
Observed every year on 20 May, International Clinical Trials Day commemorates the day in 1747 when James Lind conducted what is widely considered one of the first controlled clinical trials aboard a Royal Navy ship. This landmark moment helped lay the foundations for modern clinical research. Nearly three centuries later, clinical trials remain central to medical progress, supporting the development of new therapies, advancing scientific understanding, and bringing hope to patients and families globally.
This year, the occasion offers an important opportunity to reflect on one of the most essential principles in clinical research: keeping patients at the center of every decision.
To mark International Clinical Trials Day, we spoke with Natalia Grassis about the evolving clinical research landscape, the growing importance of patient-centricity, leadership in a fast-changing industry, and the experiences that have shaped her professional journey. Throughout the conversation, Natalia shared perspectives on her early career, the lessons that influenced her leadership approach, the future of clinical development, and why patient-focused thinking must remain at the heart of clinical research.

From First Steps to Leadership
Behind every experienced leader is a journey shaped by learning, challenges, and defining moments. Natalia reflected on what first attracted her to clinical research, the experiences that shaped her perspective, and the motivation that continues to drive her work today.
Do you remember what first attracted you to the world of clinical research? What initially attracted me was the opportunity to combine science with real human impact. Clinical research is a unique field where innovation directly connects to improving patients’ lives. Early in my career, I realized that behind every study and every milestone, there are people waiting for better treatment options, more time, or simply hope. That sense of purpose stayed with me throughout my journey.
Looking back at the beginning of your career, what lessons shaped you the most? Team work, quality and every patient matters! Very early on, I learned that success is never achieved individually — it is always the result of teams working together toward a shared purpose. We carry a big responsibility in this industry. We are part of a continue changing and evolving environment, So adaptability and resilience becomes part of our ongoing journey.
Clinical research is a fast-moving and demanding industry. What kept you motivated throughout your journey? The impact on patients has always been the greatest motivation for me. Even during the most challenging projects, it is important to remember why we do this work. Knowing that our efforts contribute to therapies that may improve or save lives gives real meaning to everything we do. I am also continuously inspired by the people in this industry — passionate experts who genuinely care about making a difference.
Was there a particular moment in your career when you truly realized the impact clinical trials can have on patients’ lives? There have been several moments. I personally have friends being patients in clinical trials and caregivers of patients. Caregivers are usually neglected, and they play a critical role in this journey. Hearing directly from patients and physicians about how access to innovative therapies changed someone’s quality of life is priceless. Those conversations remind you that clinical trials are not just about data or timelines — they are about people, families, and futures. That perspective changes how you approach every decision.
The Meaning Behind International Clinical Trials Day
International Clinical Trials Day is more than a celebration of scientific advancement. It is also a recognition of the patients, researchers, healthcare professionals, sponsors, sites, regulators, and partners who make clinical progress possible.
What does patient-centricity genuinely mean to you? Patient-centricity means making decisions with the patient perspective in mind at every stage of the process. It goes beyond strategy or terminology — it is about listening, understanding real patient and caregivers needs, and creating experiences that are respectful, accessible, and meaningful. Patients are not simply participants in research; they are the reason research exists in the first place.
How can organizations ensure patient-centricity becomes part of everyday decision-making rather than just a strategic message? It starts with culture and leadership. Patient-centricity cannot be limited to presentations or initiatives — it has to be reflected in everyday choices, from protocol design to communication and operational planning. It about being active in the community, connecting with patients advocacy groups, to ensure their voices are heard. Organizations need to actively listen to patients, involve them earlier in development processes, and encourage teams to think beyond processes and timelines toward real patient impact.
As a leader, what values do you try to bring to your teams every day? I believe in transparency, collaboration, empathy, and accountability. Strong teams are built on trust and open communication. I also think it is important to create an environment where people feel empowered to contribute ideas, challenge perspectives, and continue growing professionally.
What advice would you give to someone starting a career in clinical research today? Stay curious and never lose sight of the bigger purpose behind the work. Clinical research can be challenging, but it is also incredibly rewarding. Build strong relationships, remain adaptable, and remember that even the smallest contribution can ultimately impact patients’ lives in meaningful ways.
