ABSTRACT Biotechnology has changed the pharmacopeia. It is expected that in the next five years, 50% of biological products will originate from biotechnology. Yet, treatments based on effective, costly biopharmaceuticals for prolonged use hamper the goals of ensuring universal therapeutic coverage and access to the best treatments. This conflict surfaced 30 years ago with synthetic drugs, and the solution was to create generics once the developers’ patents expired. Biosimilars are not generics, strictly speaking, as it is impossible to guarantee that they are molecularly identical to the original product; nor are they completely new products, as they rely on a great deal of prior work done by other scientists. National strategies are needed to ensure the broadest possible coverage in the best interests of the population. The key to a strategy to ensure access to the best treatment available lies in the concept of “totality of evidence,” which includes all information about a given molecular structure and its mechanism of action; safety and efficacy information from the first clinical trials; and monitoring data from products’ use in medical practice. A strategy of broad biological and molecular categorization plus intense pharmacovigilance would reduce development costs, the main barrier to widespread access.
