1 TAXUS II: Moderate Release Formula An International, Randomized, Multicenter, Blinded Trial of TAXUSTM NIRxTM MR Stent Presented at TCT 2002

2 TAXUS II: Study Overview
Randomized 1:1 Triple-blind 536 Patients TAXUSTM NIRxTM SR (n=267) TAXUSTM NIRxTM MR (n=269) 30 day, 6 month, 1-5 year F/U Primary endpoint: % in-stent net volume obstruction (IVUS) at 6 months Inclusion Criteria Standard risk de novo lesions Length <12 mm RVD >3.0 mm & <3.5 mm Antiplatelet Regimen ASA >75 mg (loading dose and maintained indefinitely) Clopidogrel (loading dose 300mg and 75 mg q.d. for 6 months) TCT 2002

3 TAXUS II: Two Consecutive Cohorts, Slow and Moderate Release
Slow Release (SR) Moderate Release (MR) Cohort I SR = 267 DMC Cohort II MR = 269 TAXUS n = 131 Control n = 136 TAXUS n = 135 Control n = 134 30 Day Follow-up SR Follow-up Clinical: >99% Angiographic: >98% IVUS: >90% MR Follow-up Clinical: >96% Angiographic: >95% IVUS: >87% 6 Month Follow-up Annually 1-5 Years TCT 2002

4 TAXUS II: Patient Demographics
TAXUS MR (%) Control (%) p-value (n=135) (n=134) Male Mean Age (years) Prior MI Prior Intervention Diabetes Unstable Angina Hypertension Smoker Lecture Notes The dosing of the thrombolytic agent TNK is shown here. After giving informed consent, patients were randomly assigned, through a central computerized telephone system, to a body weight-adjusted single bolus of tenecteplase with either enoxaparin or with abciximab plus low-dose unfractionated heparin or with unfractionated heparin. Each patient was given a unique study number that corresponded with the number of a treatment kit. Study treatments were given on an open-label basis. Tenecteplase (TNK) was administered over 5 seconds according to body weight: patients allocated to enoxaparin or unfractionated heparin were given 30 mg if body weight was 60 kg, 35 mg if body weight was 60 to 70 kg; 40 mg if body weight was 70 to 80 kg; 45 mg if body weight was 80 to <90 kg and 50 mg if body weight was 90 kg. In patients allocated to combination treatment with abciximab, half-dose tenecteplase was given with doses ranging from 15 mg to 25 mg according to the same weight categories as with full dose. TNK-tPA is available as a lyophilized powder and should be reconstituted with Sterile Water for Injection, USP. The simple weight-based dosing regimen is designed to balance efficacy with safety. The dosing categories are about 22 lb wide (10 kg = 22 lb) which minimizes the possibility of dosing errors. The dosing schedule is as shown below: < 60 kg  6 mL kg  7 mL kg  8 mL kg  9 mL > 90 kg  10 mL References ASSENT 2 Investigators. Lancet. 1999;354: 1. The ASSENT 3 Investigators.
