Species specifi city
Another term that is frequently bandied about in the biotech drug
world is ‘species specifi city’.This means that you can’t take your drug candidate and inject it into a rodent or nonrodent species in your
toxicology studies and assume this is going to be acceptable to the
regulatory agencies.In the 1980s when the interferons were being
developed,companies assumed they could use a small molecule drug
development programme for any new biotech drug.They injected
rodents with recombinant interferons and nothing happened,not
because they were not toxic,but because they have little or no
pharmacological activity in rodents.The receptors either don’t exist or are different enough from the human receptors to cause poor binding
of the drug to its putative receptor.To evaluate the toxicity of biologics,the drug candidate must be shown to have pharmacological activity in
the animal model chosen for preclinical studies.This has necessitated
using primate models for many biopharmaceuticals,because biotech
drug receptors are not necessarily found in lower species.
But what if the drug candidate only binds to the human or
chimpanzee receptor?These types of drugs are more challenging
to develop.Some biotech drugs have been tested in chimpanzees
but the data obtained are limited to pharmacokinetic and clinical
chemistry,because necropsies are no longer permitted.In fact,
experimentation with chimpanzees is now banned in many regions,
notably the EU.One approach for these drug programmes is to develop the
analogous molecule in a lower species.An anti-TNF mouse version of
Remicade (infl iximab) (eg,cV1q) was developed and used for repeat
dose and reproductive toxicology studies in mice.Another example is
Raptiva (efalizumab),for which a surrogate antibody that binds CD11a
in mice was developed (muM17) and used in repeat dose toxicology,reproductive toxicology,and toxicokinetic preclinical studies.The ICH (International Conference on Harmonisation) guidance
(ICH S6) for preclinical development of biopharmaceuticals states
that safety evaluation should normally include two relevant species
(ie,two species in which the drug is pharmacologically active).
However,when only one relevant species can be identifi ed (or when
the biological activity of the biopharmaceutical is well understood)
it is acceptable to do toxicity testing in only one species.5 Note that
the regulatory authorities will require studies demonstrating degree
of binding of the drug to its receptor or epitope in various species to
support the choice of species for toxicity testing.

物种特异性

世界是物种特异性的.这意味着你不能把你的候选药物和注射到你的啮齿类动物或nonrodent物种
