The R&D pipeline involves various phases that can broadly be grouped in 4 stages: discovery, pre-clinical, clinical trials and marketing (or post-approval). Pharmaceutical companies usually have a number of compounds in their pipelines at any given time. The drug pipeline is an important indicator of the value and future prospects of a company ...
Drug development is the process of bringing a new pharmaceutical drug to the market once a lead compound has been identified through the process of drug discovery.It includes preclinical research on microorganisms and animals, filing for regulatory status, such as via the United States Food and Drug Administration for an investigational new drug to initiate clinical trials on humans, and may ...
In drug development, preclinical development (also termed preclinical studies or nonclinical studies) is a stage of research that begins before clinical trials (testing in humans) and during which important feasibility, iterative testing and drug safety data are collected, typically in laboratory animals.

The trials are typically conducted in three phases: [5] Phase 1: The drug is tested in 20 to 100 healthy volunteers to determine its safety at low doses. About 70% of candidate drugs advance to Phase 2. Phase 2: The drug is tested for both efficacy and safety in up to several hundred people with the targeted disease.
In 2010, the research and development cost of each new molecular entity was about US$1.8 billion. [7] In the 21st century, basic discovery research is funded primarily by governments and by philanthropic organizations, while late-stage development is funded primarily by pharmaceutical companies or venture capitalists.
