 prior to marketing and sale of drugs and drug delivery products. In addition, they require adherence to best practices as defined by the International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use, as well as national guidelines. The process for pharmaceutical development and approval are subject to inherent risks, described in "Risk Factors."

The principal steps generally required for approval of drug and drug delivery products in the United States, Canada and Europe are described below.

Preclinical Toxicology Studies

Preclinical studies are conducted in vitro and in animals to evaluate toxicokinetics and pharmacokinetics to provide evidence of the safety and bioavailability of the product prior to its administration to humans in clinical studies and throughout development. Such studies compliant with FDA guidelines have been completed.

Human Testing

The process of conducting clinical trials with a new drug product generally cannot begin until a company has submitted to the appropriate regulatory authorities an application to do so and the required number of days have lapsed without objection from the applicable regulatory authority. (In certain jurisdictions, a no objection letter or approval may be required before the clinical trial can proceed). In the United States, this application is called an investigational new drug study, or "IND", and in Canada and most European countries, a clinical trial application, or "CTA."

For the United States, the sponsor of the study must submit the results of the non-clinical tests, manufacturing information, analytical data and available clinical data or literature, within the IND, to the FDA. Some information may be omitted from the IND in instances where prior FDA findings of safety or efficacy of a drug product are being relied upon. Even once the IND is submitted, non-clinical testing may continue to occur. An IND becomes effective automatically 30 days after receipt of the document by the FDA, unless within that time the FDA raises concerns or questions, in which case a clinical hold may be put in place until the concerns are adequately addressed by the study sponsor with the FDA.

Two key factors influencing the rate of progression of clinical trials are the rate at which patients can be enrolled to participate in the research program and whether effective treatments are currently available for the disease that the drug is intended to treat. Patient enrollment is largely dependent upon the incidence and severity of the disease, the treatments available and the potential side effects of the drug to be tested and any restrictions for enrolment that may be imposed by regulatory agencies. For further information see "Risk Factors."
