 mechanism-of-action as an anti-neoplastic agent is not fully understood, but it is believed to be related to its ability to cause caspase-dependent apoptosis (Wu et. al. 2014).

Regulatory Environment

The production and manufacture of the Products and their research and development activities for use in the United States are subject to regulation for safety, efficacy and ethics by various governmental authorities in the United States. Although the present plan is to focus research and development in the United States, we might in the future expand into Canada and the European Union, in which case our activities will also be governed by regulatory authorities in these jurisdictions. These authorities, in the United States, Canada and the rest of the world, regulate research, development, testing, manufacturing, packaging, storage, recordkeeping, labeling, advertising, promotion, distribution, marketing and import/export of pharmaceutical products, among other things. In the United States drugs and biological products are subject to regulation by the FDA and in the European Union activities are regulated by the applicable competent authority within each individual country and by the European Medicines Agency. In Canada, these activities are primarily regulated by the Food and Drug Act and the rules and regulations thereunder, which are enforced by the Therapeutic Products Directorate of Health Canada.

Drug approval laws in the United States, Canada and Europe generally require licensing of manufacturing facilities, carefully controlled research and testing of products, government review and approval of results 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
