WASHINGTON, D.C.—Use of the MOXY paclitaxel-eluting balloon to treat stenosis of the femoropopliteal arteries beats the use of standard percutaneous transluminal angioplasty (PTA), proving a reduction in clinical events and a shorter duration of antiplatelet therapy, according to Dierk Scheinert, MD, of Herzzentrum Leipzig, in Leipzig, Germany, who presented results of the LEVANT I trial today at the 2010 Transcatheter Cardiovascular Therapeutics (TCT) annual meeting.

7. LEVANT I CONCLUSIONS
*ACHIEVED PRIMARY
1. Strong biologic effect demonstrated on ENDPOINT OF IMPROVED
the inhibition of neointimal hyperplasia. LATE LUMEN LOSS
2. Data suggests the Moxy DCB is safe with a marked decrease
in clinical events compared to PTA
3. Shorter duration anti-platelet therapy appears feasible in the
peripheral vasculature.
4. Large pivotal trial is warranted to further confirm the benefit
of treating SFA-popliteal lesions with a drug-coated balloon.
8. LEVANT II TRIAL: STUDY SUMMARY
DESIGN Prospective, Randomized, Multicenter, Single Blind
Assess the safety and efficacy of the Moxy Catheter for
OBJECTIVE treatment of stenosis of the femoropopliteal arteries by
direct comparison to standard PTA
Safety: Composite of freedom from all-cause
PRIMARY perioperative and 1 year index limb amputation, index
ENDPOINT limb re-intervention, and index-limb-related death.
Efficacy: Primary Patency of the target lesion at 1 year.
FOLLOW-UP To 5 years
