 to obtain authorization for human testing. Extensive clinical testing, which is generally done in three phases, must then be undertaken at a hospital or medical center to demonstrate optimal use, safety, and efficacy of each product in humans.

Phase I

Phase 1 trials are designed to assess the safety (pharmacovigilance), tolerability, pharmacokinetics, and pharmacodynamics of a drug. These trials are often conducted in an inpatient clinic, where the subject can be observed by full-time staff. The subject who receives the drug is usually observed until several half-lives of the drug have passed. Phase I trials normally include dose-ranging, also called dose escalation, studies so that the appropriate dose for therapeutic use can be found. The tested range of doses usually are a fraction of the dose that causes harm in animal testing and involve a small group of healthy volunteers. However, there are some circumstances when real patients are used, such as patients who have end-stage disease and lack other treatment options.

Phase II

Phase II trials are designed to assess how well the drug or biologic works, as well as to continue Phase I safety assessments in a larger group of volunteers and patients. Phase II trials are performed on larger groups.

Phase III

Phase III trials are aimed at being the definitive assessment of how effective the product is in comparison with current best standard treatment and to provide an adequate basis for physician labeling. Phase III trials may also be conducted for the purposes of (i) “label expansion” (to show the product works for additional types of patients/diseases beyond the original use for which the drug was approved for marketing or (ii) to obtain additional safety data, or to support marketing claims for the product.

On occasion Phase IV (Post Approval) trials may be required by the FDA. Phase IV trials involve the safety surveillance (pharmacovigilance) and ongoing technical support of a drug after it receives permission to be sold.The safety surveillance is designed to detect any rare or long-term adverse effects over a much larger patient population and longer time period than was possible during the Phase I-III clinical trials.

All phases, must be undertaken at a hospital or medical center to demonstrate optimal use, safety, and efficacy of each product in humans. Each clinical study is conducted under the auspices of an independent Institutional Review Board (“IRB”). The IRB will consider, among other things, ethical factors, the safety of human subjects, and the possible liability of the institution. The time and expense required to perform this clinical testing can far
