The moment

Brazil is on the clinical research map.

12th

Brazil's position in the global ranking of clinical trials.

Law 14.874/2024 and Decree 12.651/2025 shortened the regulatory path. Brazil rose to 12th place in the global ranking of clinical trials. Approval is no longer the problem.

The risk

Now the problem isn't approval, it's delivery.

  1. 11%

    of activated sites

    recruit no participants.

  2. 48%

    fall short

    of the enrollment target.

  3. 20%

    of selected sites

    in Latin America are never activated.

Site selection has become the highest-risk decision in a study.

Who we are

We started out with 25 years of experience behind us.

GIYUS Research Center was built on an already operating site, led by a principal investigator with years of experience in clinical and academic research and with participants in follow-up for more than six years. A new brand with an auditable track record from day one.

Who operates

Your study has a dedicated team, not a shared schedule.

The operations manager and the five senior coordinators of GIYUS Research Center

Five senior coordinators, backed by dedicated operations and quality management — not shared with routine patient care.

Inside the site

A complete facility for your research.

Clinical area

Every step of the visit has its own room.

Site rooms: reception, exam rooms, collection and infusion rooms, pantry, corridors and workstations

Pharmacy and chain of custody

Your investigational product has its own door — and an electronic witness.

Site pharmacy: door with facial recognition, −80 °C and −20 °C freezers, refrigerators and cold room

• Pharmacy access via electronic lock and facial recognition• Freezer −80 °C and freezer −20 °C• Digital thermometers monitored in real time 24/7• Refrigerator and cold room 2 °C to 8 °C

The monitor experience

Your monitor has privacy, security and immediate support.

Site monitoring space: closed workstations with glass, and the coordination team alongside

The monitoring space is exclusive, individual and private: a closed workstation and a locker with a key, where each monitor locks away their study documents, with coordination always nearby. There is a dedicated archive and an auditorium available when the sponsor needs to gather investigators or train the team on site. Monitors arrive to a ready workstation, with source documents and system access in place, without competing for space with patient care.

The manifesto

We mobilize.

Science never advances alone. It depends on people, trust, organization, speed and ethics. On those who turn knowledge into reality. That is why we exist: we mobilize researchers and sites, technology and talent, and everything science needs to move forward.
