NACDS conference discusses patent cliff, future of generics
Like a freighter in the Atlantic Ocean during hurricane season, anyone with a stake in the generic drug industry will encounter smooth and bumpy sailing alike over the next few years, according to a recent presentation by an industry expert.
IMS Health VP industry relations Doug Long appeared at the end of August at the National Association of Chain Drug Stores’ Pharmacy and Technology Conference in San Diego to talk about the current state of the drug industry and what the near future holds. Over the next decade, according to his remarks, the U.S. drug market will present opportunities as well as uncertainties.
For the generics industry, the so-called “patent cliff” is of particular concern. For the last several years, generics companies have profited handsomely from a steady supply of generic drugs losing patent protection and thus becoming open to generic competition. Under the Hatch-Waxman Act of 1984, the first company to win approval from the Food and Drug Administration for a generic version of a drug gets to compete directly with the branded version for six months, which has allowed many generics companies to grow into giants, especially Israel-based Teva Pharmaceutical Industries, which ranks as one of the largest drug makers in the world.
But that will all slow down pretty soon. A slideshow shown during Long’s presentation listed 20 drugs that will lose patent protection between 2010 and 2014, whose sales by the time of their patents’ expirations will total $107 billion; IMS estimated the expirations will dampen sales by $79 billion. These include Pfizer’s cholesterol-lowering drug Lipitor (atorvastatin calcium), currently the world’s top-selling drug, which will lose protection next year and face generic competition from Indian drug maker Ranbaxy Labs, and Purdue Pharma’s opioid painkiller OxyContin (oxycodone hydrochloride), which will lose patent protection in 2013. Eight of the drugs listed ranked on IMS’ list of the top 10 in terms of sales, while Teva will itself lose protection for one of its own branded drugs, the injectable multiple sclerosis treatment Copaxone (glatiramer acetate), in 2014. “So you have this patent cliff, which means there are going to be plenty of generic opportunities between now and 2014,” Long said.
Sales growth for the top 10 generics companies

However, 2015 is the worrisome year, the year of the patent cliff, when the number of big-name drugs losing patent protection will suddenly drop. That, Long said, could affect not just generic drug companies, but also retailers and other businesses that benefit from generics. In other words, the party won’t be over, but it’ll reach the point when a few guests remain, even though the VIP guests have left and refreshments have dwindled to flat soda and potato chips.
Despite the patent cliff, use of generics has been strong and will likely continue to remain so, and Long said that coinciding with the economic crisis, a growing trend had emerged of patients starting or continuing therapies with generics rather than branded drugs. In 2005, generics accounted for 57.7% of total prescriptions dispensed, according to IMS. By July 2010, that number came close to 75%, even as generics’ market share in terms of percentage of dollars fell from 85.4% to 80.7% during the same period. Sales for the top 10 generic drug companies have grown by 15.1% in the 12-month period ended in June, with Teva and Mylan accounting for 34.4% of generic prescriptions and Teva ranking as the eighth largest drug maker overall in terms of sales.
Among generic companies, Teva had $7.4 billion in generics sales during the 12 months ended in June as sales grew by 1.1%, and the company had a 21.3% market share. Mylan accounted for $3.6 billion in sales, while sales grew by 6.3% and the company commanded a market share of 10.3%. Other companies have grown considerably while commanding a relatively small market share. Global Pharmaceuticals, despite having 2.6% of the market and $899 million in sales, grew by nearly 277%. The U.S. subsidiary of Iceland’s Actavis had $873 million in sales and 2.5% of the market, though its sales grew by almost 75%. Only four of the companies in IMS’ top-20 list—Covidien, Dr. Reddy’s Labs, Apotex and Baxter Healthcare—had declines in sales.
On the branded side, according to the FDA and IMS, the FDA has approved fewer primary care drugs and more specialty drugs—drugs typically prescribed by specialist physicians—every year between 1998 and 2009, except for 2002. Long noted that development seemed skewed toward specialty drugs and orphan drugs, drugs used to treat rare and dangerous diseases and conditions.
Many top-selling branded drugs continue to have strong sales growth. Aside from Lipitor, which had a sales decline by 4.3%, all of the drugs that IMS listed as the top 20 in terms of sales grew during the 12 months ended in June, and sometimes quite strongly. AstraZeneca’s cholesterol-lowering drug Crestor (rosuvastatin calcium) had $3.5 billion in sales, growing by 34.7%, while the antipsychotic and antidepressant Abilify (aripiprazole), made by Bristol-Myers Squibb and Otsuka America Pharmaceutical, had $4.3 billion in sales, growing by 22.3%. Purdue’s OxyContin had sales of $3.1 billion, growing by 18.6%.
Amgen recalls certain lots of Epogen, Procrit
THOUSAND OAKS, Calif. Several lots of two drugs used to treat anemia are being recalled due to possible contamination.
Amgen said Friday that it was voluntarily recalling certain lots of Epogen and Procrit (epoetin alfa) from distributors, wholesalers, healthcare providers and pharmacies as a precaution due to the possible presence of extremely thin and barely visible glass flakes known as lamellae that result from an interaction between the drugs and the glass vials used to store them.
The drugs are used to treat anemia resulting from chemotherapy, kidney failure and HIV therapy.
