Clinical research from the inside: science, careers, and impact on health

A hybrid field within healthcare, clinical research presents challenges for which ethics, regulation, and protocols are essential to transforming science into evidence and ensuring patient safety

Multidisciplinary team representing the different stages of clinical research

I knew I wanted to work in healthcare from an early age. I grew up in the hospital environment, with my entire family working in the sector. Even so, when I started university, I had no idea there was such a thing as clinical research

After graduating in physiotherapy, I followed the expected pathway: I began my career in private practice, focusing on traditional patient care. But in 2006, a single encounter completely changed my professional perspective.

Professor Álvaro Pacheco da Silva Filho of the Federal University of São Paulo (UNIFESP), my boss at the time, introduced me to the world of clinical research through the FAVORIT study, conducted by the National Institutes of Health (NIH), which investigated whether folic acid could reduce vascular events in kidney transplant recipients.

I felt like I had discovered a new territory within medicine itself. I realized that there was a space where science and patient care go hand in hand, and where every detail, from a clinical record to the way a participant visit is conducted, has a direct impact on knowledge production.

Since then, I often say that “clinical research chose me.”

Captivated by this new world, I decided to leave private practice and pursue specialized training in the field. I started a clinical research course in June 2006, and by the time I finished it in December of the same year, I was even more certain: this was not just a new area of work, but a new way of contributing to healthcare and society.

Data security and integrity

Clinical research is one of the most dynamic and challenging career paths in the health sector. It combines scientific rigor and ethical responsibility, and has a direct impact on people’s lives.

Working in this field—whether in academic institutions or the pharmaceutical industry—means making a key commitment: to protect participant safety and ensure the integrity of study data.

This commitment is central to evidence-based medicine, allowing new therapies to be incorporated into clinical practice safely and responsibly.

Clinical research may be one of the most “hybrid” fields in healthcare, situated at the intersection of science, patient care, regulation, and project management.

As a research manager, I would say it is a particularly appealing career path for those who value organization, rigorous quality, and multidisciplinary teamwork—in addition to the opportunity to follow a study from beginning to end.

The work in practice

My career has always been linked to clinical research centers. What motivates me the most is interacting with patients and the dynamics of working alongside teams made up of doctors, coordinators, assistants, nurses, and pharmacists.

In this environment, day-to-day activities are guided by the protocol of the current study, with one clear objective: to produce scientific evidence while maintaining safety, data integrity, and ethical and regulatory compliance.

Daily activities include:

• overseeing sponsor qualification

• negotiating contracts and budgets

• submitting proposals to research ethics committees (RECs) and the National Research Ethics Commission (CONEP)

• recruiting and screening participants according to criteria defined in the study protocol

• conducting participant visits, including the collection of clinical data, vital signs, questionnaires, and biological samples

• organizing essential documentation, maintaining medical records, completing electronic case report forms (eCRFs), and managing regulatory files

• managing adverse events and communicating with the investigator, sponsor, contract research organization (CRO), and research ethics committee

• overseeing monitoring visits and audits, demonstrating process traceability and quality

Career paths in clinical research

At clinical research centers, professional development can follow various paths depending on a person’s profile and skills, such as:

Operations: Many professionals start as clinical research assistants and progress to study coordinators, senior coordinators, and eventually, research managers. This path is closely tied to managing processes, deadlines, and data quality.
Regulation: Work in this area involves handling procedures linked to RECs, CONEP, and the Brazilian Health Regulatory Agency (ANVISA), as well as the requirements of sponsors and CROs. Roles require documentary rigor, attention to detail, and precise planning of regulatory steps.
Quality: Roles include assistants, analysts, specialists, and quality managers responsible for ensuring that studies are conducted in accordance with the Good Clinical Practice guidelines established by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use. They also safeguard data integrity according to the ALCOA+ principles: attributable, legible, contemporaneous, original, and accurate, plus complete, consistent, enduring, and available.
Management: In management, the focus is on ensuring studies are carried out properly, maintaining operational capacity of the research center, and aligning the team with the principal investigator, CROs, and supporting areas. In summary: people, deadlines, and quality.

Taking part in pivotal trials—those that lead to changes in clinical practice—is an experience that is difficult to translate into numbers or reports. Every completed study represents more than statistical results; it reflects participant confidence, clinical decisions, and the possibility of expanding treatment options.

Brazil is currently going through an important change in this field with the enactment of the Clinical Research Law (Law 14.874/24).

The new legislation establishes clearer rules on how clinical studies are approved and conducted, creating greater predictability and legal certainty.

By potentially streamlining these processes, Brazil hopes to become more internationally competitive, increasing its participation in global research and attracting investment in innovation.

This means more opportunities for research centers, more high-skilled jobs, and above all, greater access to new therapies for patients.

Learning curve

For those interested in entering the field, the learning curve is often steep. Some of the fundamental elements include:

Ethics and rigor. A solid understanding of Good Clinical Practice (GCP) is indispensable. More than a formal requirement, it guides every day-to-day decision.

Organization and traceability. Clinical research involves multiple deadlines, regulatory documents, training sessions, and biological samples. Control systems and verification routines are essential tools.

Communication and soft skills. Communicating with researchers, sponsors, and patients—often in sensitive contexts—requires clarity, empathy, and the ability to translate technical terms.

Continuous regulatory updates. Keeping up-to-date with rules set by ANVISA, CONEP, and RECs, as well as legislative changes, is a fundamental part of the job.

Ultimately, clinical research is more than just a career. It is a link between science and patient care, between data and medical decisions. Behind every study protocol is a silent commitment: to transform scientific knowledge into better outcomes for people’s health.
