A Randomized Controlled Comparison Between One Versus More Than Six Months of Dual Antiplatelet Therapy After Biolimus A9-eluting Stent Implantation

March 2, 2020 updated by: Yonsei University
DES are preferred over BMS for most patients, however prolonged dual antiplatelet therapy is required for patients treated with DES for prevention of late or very late stent thrombosis. which increases a risk of major bleeding. BioFreedom is a Biolimus A9-coated stent that consists of a stainless steel stent platform with a textured abluminal surface without use of any polymer in the coating. Biolimus A9 rapid release and polymer-free property may give BioFreedom the advantages of both DES and BMS that may require less duration of DAPT. BioMatrix Flex, Biolimus-eluting stent with biodegradable polymer, also demonstrated safety and efficacy. We will compare these two difference types of Biolimus A9-eluting stents with different duration of DAPT. With proven adequate and safe duration, we will compare between one versus more than six months of dual antiplatelet therapy after Biolimus A9-eluting stents implantation using different properties of BioFreedom and BioMatrix Flex.

  • Interventional Model: Parallel Assignment
  • Masking: None (Open Label)

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Short-term DAPT after Biofreedom
Device: BioFreedom with 1 month DAPT
The cath lab will follow site standard operating procedures for PTCA and stenting. Information will be collected and recorded on the treated study vessel including angiographic parameters. Dual antiplatelet therapy after PCI will be continued for 1 month.
Active Comparator: Long-term DAPT after BioMatrix or Ultimaster
Device: BioMatrix or Ultimaster with 6 to 12 months DAPT
The cath lab will follow site standard operating procedures for PTCA and stenting. Information will be collected and recorded on the treated study vessel including angiographic parameters. Dual antiplatelet therapy after PCI will be the duration of dual antiplatelet therapy will be 6 to 12 months at the discretion of the interventionist.
