AstraZeneca appears set to follow Merck into the market for “bio-similars.” (See AstraZeneca may join generic rush.)
Congress and the media tend to portray biosimilars are analogous to
generic chemistry-based pharmaceuticals, and therefore believe that
they will lead to much lower prices as a result of the commoditization
of these products. If all goes according to plan, that should cut the
price of biologics by 50 to 95 percent as has been the case for generic
versions of traditional pharmaceuticals.
Pharma and biotech companies aren’t seeing it this way and neither
am I. Although they won’t say so, pharma companies are starting to
realize that biosimilars –which unlike traditional generics cannot be
subsituted by a pharmacist for a branded product– are really like
me-too products within a class of drugs. That’s exactly the model
that’s enabled multiple blockbusters within a given class in the
mainstream pharma business, and led to higher spending overall.
Biosimilars are unlikely to be a lot cheaper than the products they
copy, and they will have all the sales and marketing costs associated
with a branded product, plus some of the development costs. Don’t be
surprised if some biosimilars are actually priced higher than
the original products, based on some real or perceived improvement in
efficacy or safety. That’s what happened when me-too drugs like Lipitor
entered the statin market. (See Generic biologics — or Me Too Drugs 2.0? for more details.)
