Brief Summary:
The purpose of this study is to assess the safety and efficacy of the Danubio Paclitaxel Eluting Balloon for the treatment of side branches of de novo bifurcation lesions in native coronary arteries.

Condition or disease Intervention/treatment Phase
Coronary Disease Device: Danubio paclitaxel-eluting balloon Not Applicable

Detailed Description:

The DEBSIDE clinical trial is a prospective, non-randomized, multicenter, interventional study evaluating the investigational Danubio Paclitaxel Eluting Coronary Balloon for the treatment of Side Branches (SB) of de novo bifurcation lesions with a side branch reference vessel diameter ≥2.0 mm and ≤3.0 mm. During the procedure, a dedicated drug-eluting bifurcated stent will be implanted in the main branch. The trial will allow the treatment of lesion of all Medina type except (0,0,1) in native coronary arteries with sequential predilatation of the main and side branch.

The DEBSIDE clinical trial will enroll 60 patients. All patients will receive Quantitative Coronary Angiography (QCA) before and after Drug-Eluting Balloon (DEB) inflation and at 6 months follow-up. All patients will have a clinical follow-up at 1, 6 and 12 months.

Arm Intervention/treatment
Experimental: Danubio Device: Danubio paclitaxel-eluting balloon
Inflation of the Danubio Paclitaxel Eluting Balloon in the side branch of a de novo bifurcation lesion.

Primary Outcome Measures :
  1. Late Lumen Loss (mm) in Side Branche (SB) [ Time Frame: 6 months post-procedure (up to 26 weeks) ]
    Late Lumen Loss at the ostium of the SB (within 5mm from the carina) by Quantitative Coronary Angiography (QCA).

Secondary Outcome Measures :
  1. In-stent Late Lumen Loss (mm) in Main Branch (MB) [ Time Frame: 6 months post-procedure (up to 26 weeks) ]
    In-stent Late Lumen Loss in the MB by QCA.

  2. Angiographic Binary Restenosis rate (%) [ Time Frame: 6 months post-procedure (up to 26 weeks) ]
    Angiographic binary restenosis rate (%) in the side and main branches by QCA.

  3. Major Adverse Cardiac Event (MACE) rate [ Time Frame: In-hospital, 1, 6 and 12 months post-procedure. ]
    MACE defined as death, Myocardial Infarction (MI, Q waves and non-Q waves), emergent cardiac bypass surgery, or any target lesion revascularization (repeat Percutaneous transluminal coronary angioplasty (PTCA) or Coronary artery bypass grafting (CABG)).

  4. Clinically-driven Target Lesion Revascularization (TLR) [ Time Frame: 1, 6 and 12 months post-procedure ]
  5. Target Vessel Failure (TVF) [ Time Frame: 1, 6 and 12 months post-procedure ]
  6. Target Vessel Revascularization (TVR) [ Time Frame: 1, 6 and 12 months post-procedure ]
  7. Angiographic success [ Time Frame: Day 1 ]

Ages Eligible for Study:   18 Years and older   (Adult, Older Adult)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. De novo bifurcation lesions following the Medina classification except (0,0,1).
  2. Reference diameter main branch >= 2.5 and ≤ 3.5 mm and side branch >= 2.0 and ≤ 3.0 mm.
  3. Main branch lesion length ≤ 26mm and side branch lesion ≤ 6mm.

    • For a 24mm stent in the main branch: main branch lesion length ≤ 14mm proximal and ≤ 12mm distal to the carina.
    • For a 18mm stent in the main branch: main branch lesion length ≤ 8mm proximal and ≤ 12mm distal to the carina.

    Indeed an additional stent (Amazonia PAX 8mm) can be overlapped distally with the Nile PAX if a target lesion segment ≤4mm remains uncovered after implantation of the bifurcated stent.

  4. Maximum two bifurcation lesions per patient on two different vessels with at least one lesion treated with the procedure described on the protocol (involving the Danubio).
  5. The side branch of the bifurcation involving the target lesion must be treated with the trial device (Danubio).
  6. During the index procedure, in case of:

    • Treatment of a lesion in a vessel other than the target vessel or,
    • Treatment of a lesion in the target vessel distal to the target bifurcation lesion, The treatment of the non-target lesion must be successfully performed with a Drug-Eluting Stent before the treatment of the target lesion (residual stenosis <30%; stent well deployed; no residual dissection; normal TIMI flow; no chest pain; ECG unchanged compared to pre-procedural ECG).
  7. Successful sequential main branch and side branch predilatation with a conventional balloon providing good angiographic result (i.e. absence of dissection, TIMI > III).
  8. The patient is at least 18 years of age.
  9. Non menopausal women must provide a negative pregnancy test and use a double contraception until the end of the study.
  10. The patient has clinical evidence of ischemic heart disease, stable or unstable angina with signs of ischemia, silent ischemia, or a positive functional test.
  11. The patient is an acceptable candidate for percutaneous transluminal coronary angioplasty (PTCA), stenting, and emergent coronary artery bypass graft (CABG) surgery.
  12. The patient or patient's legal representative has been informed of the nature of the trial and agrees to its provisions and has provided written informed consent as approved by the Ethics Committee (EC).
