AGENT IDE Clinical Trial

AGENT Investigational Device Exemption (IDE) is a prospective, multicenter, randomized controlled trial in the United States to evaluate the safety and effectiveness of the AGENT™ Drug-Coated Balloon compared to balloon angioplasty in patients with ISR.¹ 

AGENT IDE Study Design
 

Primary Endpoints at 1 year, 2 years & 3 years

Primary Endpoints at 1 year, 2 years & 3 years
 

Primary Endpoint Met at 1-Year²

AGENT DCB showed statistically superior outcomes compared to balloon angioplasty for TLF at 1-year. (17.9% versus 28.7%, P=0.0063). 
 
TLF relative risk reduction for TLF

2-Year Data Highlights³

Statistically lower rates of TLF in patients that received AGENT DCB versus Balloon Angioplasty: 27% reduction in the rate of TLF (P=0.04)

These differences were driven by:

  • 37% reduction in the rate of first TLR after treatment with AGENT versus BA (P=0.009)
  • 69% reduction in the rate of subsequent TLRs (P=0.002)

No definite/probable thromboses in the AGENT DCB arm versus BA (0% vs. 3%, P=0.0004)

Recurrent TLR Through 2-Years
 

3-Year Data Highlights⁴

  • AGENT IDE is the first RCT conducted in the US examining the efficacy and safety of DCB in patients with coronary ISR
  • AGENT DCB was superior to conventional balloon angioplasty for the primary endpoint of TLF at 1-year
  • Consistent results were observed through 3 years of follow-up after treatment with AGENT DCB compared with BA:
    • 28% reduction in TLF, with 35% reduction in first TLR and 42% reduction in first TV-MI
    • Recurrent TLR analysis: More repeat events per patient with BA, including multiple TLRs
    • One definite/probable ST with AGENT vs 7 in the BA arm (0.3% vs. 3.8%; P=0.001)
  • These data support the use of AGENT DCB for the treatment of coronary ISR
     
The patient population was complex, with 51% diabetics and 43% having multiple layers of stent.
AGENT DCB delivers a targeted therapeutic dose of paclitaxel to minimize restenosis without introducing an extra layer of metal.
These findings support the continued use of AGENT DCB for the treatment of coronary ISR.
 

Antiplatelet Therapy

DAPT with aspirin and a P2Y12 inhibitor was required for at least 1-month post-procedure. Antiplatelet monotherapy was continued thereafter for the entire duration of the study.
