Conducting Clinical Trials

Merck conducts clinical trials worldwide to evaluate the safety and effectiveness of our products. These trials are fundamental to the development of innovative medicines and vaccines that treat and prevent illness.

In 2004 alone, Merck invested more than $4 billion globally in research and development of innovative medicines and vaccines that address unmet medical needs. This is four times what the Company spent on R&D just fifteen years ago.

Our clinical trials are consistently designed, conducted and monitored, whether they take place in the United States or elsewhere around the world. More than half our clinical trials are conducted outside the United States, in more than 50 countries.

Clinical trials are conducted with extensive input from local clinical investigators, external consultants and, in some cases, patient advocacy groups. All protocols are reviewed and approved by external, independent Institutional Review Boards (IRBs) or Ethical Review Committees (ERCs).

The Merck Code of Conduct for Clinical Trials is attached to every Merck protocol. By signing the protocol documentation, a clinical investigator pledges to adhere to the principles in the Code, which addresses patient welfare, the voluntary nature of participation in a research study, informed consent and payment of investigators (or their institutions) and patients. The Code also addresses the Company's commitment to publish the results of hypothesis-testing studies, regardless of the outcome.

Informed Consent

It is Merck policy that all investigational studies be carried out consistent with legal statues and regulations for the protection of patients, including protection of patient privacy. Merck requires that all patients involved in clinical trials or their legal representatives understand the procedures, use and disclosure of personal information, uses of biological samples and the risks and benefits involved in a study.

Merck also requires assurances that a person's participation in a study is voluntary. Consent must be obtained before any screening procedures begin; in addition, trial participants must be made aware of any significant new information that may affect their willingness to continue to participate in the trial.

Merck clinical studies are consistent with standards established by the Declaration of Helsinki and comply with all applicable laws, rules and regulations.
