Purpose

The Centre de recherche Saint-Louis’ purpose is quite simple: increase the quality of living for all human beings. This same purpose drives our team of experts to conduct in-depth research in a whole array of medical fields as complex as they are diverse. To continually strive towards meeting our goals, we have been working in close partnership with the largest pharmaceutical consortia for more than 10 years now, associations that share our great desire to improve health care. The Centre de recherche Saint-Louis is the expression of a simple objective, enabled by carrying out comprehensive research.

Why participate? 

Clinical research is essential to the development of safe and effective medications. While the whole research and development process typically takes more than a decade, only the very last steps involve human participation. Without the implication of participants like you, developing new medications and improving existing ones would be nearly impossible. Participating means contributing to the progress of medical research and receiving generous financial compensation, as well as a complete health check.

Can I participate?

Our participants are volunteers from all walks of life. The recommended selection criteria for each individual study ultimately determines which candidates are chosen for any given research. We therefore invite you to consult the Ongoing studies page of our website, where you will find all the necessary information for each study..

Side effects 

During your first visit, we will explain all the possible side effects with regards to the medication you will be testing. Rest assured: our team of medical professionals will constantly be at your side to assist you in any way necessary. You can also contact us at any time after the study if you notice any side effects at all.

 

The four phases of clinical studies 

 

Phase I 

Type I clinical studies aim to evaluate the harmlessness – the absence of risk in taking a medication – and pharmacokinetics – “the branch of pharmacology concerned with the movement of drugs within the body” (Source: Oxford Dictionaries) – of experimental drugs. Type I studies typically take anywhere between a few days and several weeks to complete, and require the hospitalization of a limited number of healthy volunteers for the duration of the study.

Phase II 

Type II clinical studies aim to identify the effectiveness of an experimental drug when tested on a homogeneous sample of volunteers afflicted by a diagnosed disease. Type II studies typically take anywhere between a few months and several years to complete and are conducted on a group of a few dozen individuals. Usually randomized (subjects distributed randomly), these studies focus on the critical evaluation of the tolerance to side effects / effectiveness ratio of the product.

Phase III

Type III clinical studies typically take anywhere between a few months and several years to complete and are conducted on a larger sample of volunteers afflicted by a diagnosed disease than was used for the previous phase. A larger sample allows researchers to gather more information on the experimental medication under study to better compare it with drugs usually used, or, where appropriate, to a placebo.

Phase IV

Type IV clinical studies are carried out for observation or documentation purposes following the commercialization of a drug. These studies generally include a large number of volunteers from various countries, all of whom are afflicted by a diagnosed disease. Type IV studies allow to colligate, from a very large sample, different results susceptible of helping improve a drug (side effects, efficacy, dose, interaction, etc.).
