Before they may receive approval for use, medicine and vaccine candidates undergo rigorous and systematic testing in volunteers. This process is designed to evaluate whether a new product should be approved for use in the broader population.
Each clinical trial is designed to answer certain research questions. They follow strict, predefined protocols to ensure safe and accurate results. Each phase has a different purpose in the development of a medicine or vaccine:
At Merck, our clinical trials are designed, conducted and monitored in adherence to the same standards, whether they take place in Canada or elsewhere around the world. In conducting clinical trials, we also adhere to the guidelines of The International Conference on Harmonisation of Technical Requirements for Registration of Pharmaceuticals for Human Use.
Merck-sponsored clinical trials in patients are registered on ClinicalTrials.gov, a service of the U.S. National Institutes of Health. Information about ongoing clinical trials is also available online through the International Federation of Pharmaceutical Manufacturers & Associations (IFPMA).
Note: Merck and Schering-Plough have combined our global operations under the name
Merck & Co., Inc. We are working to update our entries in these two online registries to reflect
this change. In the meantime, you can search for information about our ongoing clinical trials by
using both "Merck" and "Schering-Plough" as search terms.
We are committed to the timely registration of clinical trials in patients and disclosure of those clinical trial results regardless of their outcome. We seek to provide balanced and accurate information about our studies, and have strict guidelines in place to guide publication. We also disclose medically important safety data from other studies. In addition to publishing our clinical trial results in peer-reviewed medical journals, we post study results of our marketed products on ClinicalTrials.gov
