Text Extraction
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.
