This category links to companies actively involved in research and development of their potential therapeutic products, derived from biological rather than chemical synthesis.

This category is reserved for sites that demonstrate activity in research and development of potential biopharmaceutical products, for marketing by the same company. Companies specializing in one or two specific areas, should submit their site to the most appropriate specialist category instead.

Sites for companies that perform their own research, but do not include details on their site, may be found by following links in the Manufacturing category. This includes sites where the only reference to research and development is about clinical trials on existing products.
Sites for companies that perform research for other biopharmaceutical companies either holding patents, or that will manufacture the drug under a different company name may be found by following links in Outsourcing.
