Abstract
Introduction
A few years after their introduction in 2002, drug-eluting stents had all but
replaced bare-metal stents in the treatment of coronary heart disease,
capturing up to 90% of the market. Physicians favored the new stents primarily
because of their ability to minimize the risk of restenosis associated with
bare-metal stents. Recently, however, new safety concerns have begun to erode
the market share of drug-eluting stents. The promise of next-generation
drug-eluting stents that are beginning to emerge-including Medtronic' s
Endeavor, expected to launch in the United States in late 2007, and Abbott' s
Xience, currently in clinical trials in the United States and Japan-is likely
to help the drug-eluting stent market rebound from its current low. However,
lingering safety concerns and the possibility of competitive pricing may keep
the market from achieving its earlier high.
Get the Answers You Need to Shape Your Strategy
- The need to effectively compete with the next generation of drug-eluting
stents has prompted the current market leaders-Johnson & Johnson and Boston
Scientifi c-to acquire companies with next-generation stents in their
pipelines. How do next-generation stents differ from currently available
drug-eluting stents? Will the recent mergers of Boston Scientifi c and Guidant
and Johnson & Johnson and Conor Medsystems help the market leaders to retain
their market dominance?
- Recent concerns that drug-eluting stents are associated with increased
risk of late stent thrombosis arise from data on just two products-Boston
Scientifi c' s Taxus stent and Cordis/Johnson & Johnson' s Cypher stent. What
competitive opportunities does the potential for late stent thrombosis offer
to manufacturers of other drug-eluting stents? How do current concerns about
the risk of late stent thrombosis affect the outlook for Medtronic' s Endeavor
stent, if it receives approval in the United States?
- To acquire Guidant, Boston Scientifi c not only took on a heavy debt load,
it also struck a deal with Abbott Laboratories that gave Abbott rights to
Guidant' s Xience V DES platform. Was the decision to acquire Guidant a good
strategic move for Boston Scientifi c? Will Boston Scientifi c' s privatelabel
Xience stent, Promus, affect the company' s overall sales of drug-eluting
stents?
- Recent safety concerns about drug-eluting stents have dampened the early
enthusiasm for this technology. How is the FDA likely to respond to the
recent safety concerns about drug-eluting stents? Is the drug-eluting stent
market likely to rebound from its recent fall?
- In March 2007, Medtronic released two-year results from the largest and
longest drug-eluting stent clinical trial program to date. What advantages
does Medtronic' s Endeavor stent offer over existing drug-eluting stents? How
is the availability of the Endeavor stent likely to affect the market share of
the Taxus and Cypher stents?
Scope
- Use of stents in coronary heart disease: the limitations of
“balloon” angioplasty; introduction of bare-metal stents; the
advantages and mechanisms of drug-eluting stents.
- Market leaders: Boston Scientifi c' s Taxus versus Cordis/Johnson &
Johnson' s Cypher; the takeover battle for Guidant.
- Recent concerns: the risk of late stent thrombosis; discontinuation
of antiplatelet therapies; the effects of drug-eluting stents on coronary
collateral functions; FDA conclusions.
- Emerging innovations: new stents from Medtronic, Abbott/Boston
Scientifi c, Conor Medsystems, and Biosensors.
- Outlook: upcoming diffi culties with regulatory approval; potential
growth of antiplatelet medications; the emergence of competitive pricing;
future competition from bioabsorbable stents.
