why weresearch

Research is one of the main strategic principles at the Clínica, with special emphasis on the development of lines of translational research. Our objective is to quickly apply our results in order to improve our patient care, perfect our diagnoses, improve our treatments and help find cures. 

Our experts collaborate with the Center of Applied Medical Research (CIMA) and the Science faculties at the University of Navarra. The biggest lines of research currently being developed are in Oncology, Haematology, Hepatology, Psychiatry, Cardiology, Neurology and Ophtalmology.

The Clínic promotes and facilitates clinical research work in alll its phases though its Central Unit of Clinical Trials [SP] and Clinical Research Unit [SP].

what is aclinical trial

A clinical trial with medicines is a research project conducted on human beings with the objective of describing or verifying the effects of medications for the purpose of defining their effectiveness and safety.

In order for one to appreciate the importance of clinical trials, it is important to underscore that nearly all the treatments available at this time are the direct result of clinical research.

These studies represent opportunities for new therapeutic lines for patients who have exhausted all the standard treatments.

Phases of a trial

Phase I
The study is conducted on healthy volunteers, people in a good state of health who do not have the disease for which the medicine is being tested. The research centers on the safety of the medication in humans.

Phase II
The new medication is administered to a limited number of ill patients for a short period of time. The objective is to obtain preliminary data on its safety and benefits with respect to the disease's treatment or prevention. Unlike in Phase I, Phase II patients suffer from the disease in question.

Phase III
This is the last link in the trial process for new medicines on humans. When Phase III studies are completed and the researcher can demonstrate that the medicine is safe and effective under certain conditions, at this point the government can approve its release onto the market. During this phase the number of ill patients to whom the new medication is administered is much greater.

Phase IV
This is carried out once the medicine is already on the market. It generally measures the effects of the medicine in the long term or studies new indications.

Types of clinical trials

When everybody involved in the trial knows that the treatment is being tested.

The researchers know the treatment that is being employed, but the patients do not know who amongst them is receiving the medication being tested and who is only receiving a placebo.

Double blind
Neither the researchers nor the patients know who is actually receiving the treatment. Only the researchers can verify the medication administered to a patient, if necessary to protect his safety.

what we do


These are studies conducted on healthy volunteers.

The University of Navarre's Clinical Research Unit conducts these types of trials at specialized facilities and with a team of multidisciplinary professionals.


These are studies in which patients with the disease participate, or other clinical organizations that can contribute to the research.

At the Central Unit of Clinical Trials management of and attention to patients in trial phases II, III and IV are unified.
