As many of you know, the pharmaceutical industry has been trending downward for the past year or so. Weak pipelines, uncontrolled corporate expansion and soaring drug prices have been offered to explain the recent down turn. However, the real back story to the downturn is the loss of future revenues that is expected to occur starting in 2010 when many current blockbuster pharmaceutical products, e.g., Lipitor (Pfizer), Plavix (Sanofi Aventis), Avandia (GlaxoSmithKline), Zyprexa (Lilly), and others lose patent protection.
The loss of patent protection of branded blockbuster products is almost always accompanied by the development and subsequent, regulatory approval of lower cost, generic versions of the drugs. The Hatch Waxman Act permits generic manufacturers to begin to develop generic versions of branded products five years prior to patent expiry. This allows generic manufacturers to develop and gain regulatory approval of their products well in advance of a patent expiry date. Further, generic manufacturers usually launch their products (and flood the market) with generic versions of a branded product on the same day that its patent lapses. To induce and hasten generic development, Hatch Waxman grants market exclusivity for 180-days (6 month) to the first company that gains US regulatory approval for a generic version of a branded product that has lost patent protection.
Revenue generation and a company’s market share of branded drug products generally fall precipitously following introduction of less costly, generic versions of the drugs. From a financial standpoint, this is not surprising—why would anybody chose to pay more for a branded product when there is a cheaper and therapeutically efficacious generic alternative available? In the past, most pharmaceutical companies chose to neglect (and ultimately abandon) blockbuster products after generic versions were introduced. Many companies chose this strategy because, in the past, there was always another blockbuster in the pipeline that would replace the lost revenues caused by generic competition.
Unfortunately, as we all know, the days of the billon-dollar-a year blockbuster drug are long gone! This realization has caused many pharmaceutical companies to rethink their business strategies when a blockbuster drugs lose patent expiry. Many pharmaceutical companies are experimenting with a relatively new kind of product called an authorized generic–a copycat version of a company’s branded drug that is sold through a licensing agreement between the innovator company and a generic-drug manufacturer. This type of arrangement allows the innovator company to hold on to a larger share of a revenue stream from the drug once it loses patent protection and it falls prey to generic manufacturers.
Authorized generics have always made sense to me–who knows how to manufacture, market and distribute a drug better than the company that originally created it? Further, why would a company choose to give up on a revenue stream simply because a product can no longer generate billions each year due to generic encroachment– wouldn’t hundreds or even tens of millions suffice? Much to my surprise, late last week, Merck & Co announced that it had inked a deal for an authorized generic form of its blockbuster osteoporosis drug Fosamax after the US patent expires on February 6. Merck did not disclose the terms of the deal or the identity of it generic manufacturing partner.
Industry analysts have suggested that cheaper generics will not only batter sales of Merck’s Fosomax but could also hurt rival Actonel (Proctor & Gamble Co/Sanofi-Aventis) and Boniva (Roche/GalxoSmithKline). Generic manufacturers. Barr Laboratories and TEVA are expected to launch their own generic versions on February 6 and share the 180-day market exclusivity for their respective products.
Merck, once a champion of the old pharma blockbuster model, is slowing emerging as an industry innovator. The company’s recent decision to authorize a generic version of one of its former blockbuster drugs may be a harbinger of things to come in the pharmaceutical industry. That said, I don’t understand why big biotechnology companies like Amgen, Biogen/IDEC and Genentech are unwilling to consider the authorized generic model to stave off generic competition for blockbuster biotechnology products like EPO, Avonex and Rituxan. Whether these companies like it or not, I believe that biogenerics aka follow-on biologics will be a reality in the US in the next five years. Maybe Amgen can bolster is rapidly falling stock price by inking an authorized generic deal for EPO—rather than spending hundreds of millions on patent litigation—“whadda ya think?”
Until next time…
