| TAXUS II.
In 2002, we released our six-month data from TAXUS II, which tested
the effects of both the slow- and moderate-release platforms. The
results were very promising. TAXUS II is a 536-patient, 15-country,
randomized, double-blind, controlled study of the safety and efficacy
of a TAXUS paclitaxel-eluting coronary stent, in which two sequential
cohorts of patients with standard risk, de novo coronary
artery lesions were treated. The slow-release formulation cohort
reported an in-stent binary restenosis rate of 2.3 percent and an
in-segment binary restenosis rate of 5.5 percent. The moderate-release
formulation cohort reported an in-stent binary restenosis rate of
4.7 percent and an in-segment binary restenosis rate of 8.6 percent.
The rates for the control group were 19 percent for in-stent binary
restenosis and 22 percent for in-segment binary restenosis. In-segment
includes the stent length plus 5mm on either end of the stent. The
six-month MACE rates for TAXUS II were 19.8 percent for the control
versus 8.5 percent for the slow-release formulation cohort and 7.8
percent for the moderate-release formulation cohort.
In comparing TAXUS I and II, we saw notable consistency
between our clinical endpoints, our IVUS endpoints, and our Quantitative
Coronary Angiography endpoints. This consistency is more important
than any single trial on its own merits because the combination
of preclinical work and early clinical consistency indicates a high
degree of probability that subsequent clinical trials will perform
similarly.
