a seeding trial or marketing trial is a form of marketing, conducted in the name of research, designed to target product sampling towards selected consumers. in the marketing research field, seeding is the process of allocating marketing to specific customers, or groups of customers, in order to stimulate the internal dynamics of the market, and enhance the diffusion process. in medicine, seeding trials are clinical trials or research studies in which the primary objective is to introduce the concept of a particular medical intervention—such as a pharmaceutical drug or medical device—to physicians, rather than to test a scientific hypothesis.
