SELUTION4BTK Trial

April 27, 2026 updated by: M.A. Med Alliance S.A.

SELUTION SLR™ 014 BTK: A Prospective Randomized Multicenter Single Blinded Study to Assess the Safety and Effectiveness of the SELUTION SLR™ 014 Drug Eluting Balloon in the Treatment of Below-the-Knee (BTK) Atherosclerotic Disease in Patients With Chronic Limb Threatening Ischemia (CLTI)

This study aims to demonstrate superior efficacy and equivalent safety of the SELUTION SLR™ DEB 014 compared to plain (uncoated) balloon angioplasty in the treatment of peripheral arterial disease (PAD) in the BTK arteries in CLTI patients.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Ages Eligible for Study

14 years and older (Adult, Older Adult)

Accepts Healthy Volunteers

No

Description

Clinical Inclusion Criteria:

  1. Subject age is ≥ 18 years or older depending on local regulations.
  2. Subject life expectancy is ≥ 1 year.
  3. Subject has documented chronic limb-threatening ischemia in the target limb with Rutherford classification category 4 or 5 and symptoms of > 2 weeks duration.
  4. Subject is willing and able to provide written informed consent and comply with study procedures and required follow-up evaluations.
  5. Female subjects of childbearing potential must be non-breastfeeding and have a negative pregnancy test ≤ 7 days before the procedure.

Angiographic Inclusion Criteria:

Subjects must meet all the following criteria to be enrolled in the trial:

  1. Target lesion(s) must be de novo or non-stented restenotic lesion(s) located within the BTK arteries distal to the tibial plateau and above the tibiotalar joint line. BTK arteries include the P3 segment of the popliteal artery, the tibio-peroneal trunk, peroneal artery, anterior tibial artery, and posterior tibial artery.
  2. BTK Target lesions cannot be contiguous with inflow lesions and at least 3 cm of normal artery should extend beyond the tibial plateau to ensure there is no overlap.
  3. Target lesions must have a diameter stenosis of ≥ 70% (including total occlusions) by visual estimate and must be indicated for PTA treatment.
  4. Target vessel reference diameter(s) are ≥ 2mm and ≤ 4mm. Note: the SELUTION SLR 014 DEB and the control PTA balloon size cannot exceed 4.0 mm.
  5. Target lesions must be confined to a single target vessel. NOTE: Subjects with other non-target BTK lesions in separate non-target vessels may be enrolled, provided that the non-target lesions have been successfully treated (residual stenosis ≤ 30% with no distal embolization or flow limiting ≥ Grade C dissection). NOTE: Any adjunctive therapies are permitted for the treatment of non-target BTK lesions, but no DEB or DES may be used.
  6. Any target lesion must be ≥ 30 mm in length and the total combined length of all target lesions must be ≤ 140 mm (total treatment length ≤ 150 mm allowing for 5 mm proximal and distal shoulder treatment). Note: All target lesions and all inflow lesions must be treatable by one or more SELUTION SLR 014/018 DEB(s) such that the total planned per-subject drug dose (calculated by summing the drug dose of all individual planned balloon sizes) would be ≤ 7069 μg. Note: A total treated segment length of ≤ 150 mm for BTK and ≤ 200 mm for inflow segment is acceptable irrespective of DEB balloon diameter.
  7. The tibial and pedal runoff distal to the target lesions must be patent OR the target vessel(s) must reconstitute above the ankle or display normal terminal branching as follows:

    1. If the target vessel is the P3 segment, any 1 of the 3 distal arteries must show a patent (≤ 50% stenosis by visual estimate) outflow.
    2. If the target vessel is the peroneal artery, the artery must demonstrate normal terminal branching.
    3. If the target vessel is the anterior tibial (AT) or posterior tibial (PT) artery, the artery must reconstitute ≥ 1 cm above the tibiotalar joint to provide an intact runoff vessel (AT: dorsalis pedis; PT: plantar artery).
    4. If the target vessel is the tibio-peroneal trunk, outflow for either the peroneal OR the posterior tibial artery must be patent (≤ 50% stenosis by visual estimate).
  8. Subjects is free of significant inflow vessel disease or any inflow disease has been successfully treated (see angiographic inclusion # 9). Significant inflow disease is defined as ≥ 50% stenosis by visual estimate. Inflow vessels include the ipsilateral common iliac, external iliac, common femoral, profunda femoris, superficial femoral or popliteal artery proximal (≥ 3 cm) to the tibial plateau. Note: If access site doesn't permit angiographic imaging of the common iliac and common femoral artery (CFA), then non-invasive imaging (CTA or MRA) must be provided to exclude presence of significant inflow disease. If non-invasive imaging is not possible, a DUS of the CFA with a multiphasic wave form excluding significant disease AND a palpable ipsilateral femoral pulse must be documented.
  9. Subjects with significant inflow disease (≥ 50% stenosis by visual estimate) must have documented successful treatment before randomizing the subject. Successful treatment of inflow disease is defined as ≤ 30% final residual stenosis and no distal embolization or flow-limiting > Grade C dissection. Note: Treatment of the common femoral and profunda femoris is not permitted. Inflow vessel treatment can be performed with any commercially available non-DCB or non-DES device; if DCB treatment is required, SELUTION SLR 018 must be used.
  10. The BTK target lesion preparation must be documented to be successful by angiography (≤ 30% residual stenosis and no distal embolization or flow-limiting ≥ Grade C dissection) before randomization. Note: Lesion preparation can include atherectomy (rotational, orbital, directional or laser), cutting, scoring, contoured balloons or intravascular lithotripsy and PTA only.

1, 6, 12, 24, and 36 months
Quality of Life (QOL) measures
Time Frame: 1, 6, 12, 24, and 36 months
A secondary efficacy endpoint defined as change in Quality of Life (QOL) measures from baseline (EQ-5D and VascuQol instruments).
1, 6, 12, 24, and 36 months
MALE
Time Frame: 1, 6, 12, 24, and 36 months
A secondary safety endpoint defined as the composite of major (above-the-ankle) amputation or major reintervention (new bypass graft, jump/ interposition graft revision, thrombectomy/thrombolysis) of the index limb.
1, 6, 12, 24, and 36 months
Major cardiovascular events
Time Frame: 1, 6, 12, 24, and 36 months

A secondary safety endpoint defined as the composite of cardiovascular death, myocardial infarction (MI), and stroke.

• All-cause mortality [evaluated at discharge, 1, 6, and 12 months and 2-5 years]

1, 6, 12, 24, and 36 months
All-cause mortality
Time Frame: 1, 6, 12, 24, and 36 months
1, 6, 12, 24, and 36 months
Device success
Time Frame: Post-procedure
A secondary performance endpoint defined as successful delivery, balloon inflation, deflation and retrieval of the intact investigational device.
Post-procedure
Procedural (technical) success
Time Frame: Post-procedure
A secondary performance endpoint defined as device success and residual diameter stenosis ≤ 30% on completion angiography by core lab assessment.
Post-procedure
Clinical success
Time Frame: Evaluated at discharge defined as immediately prior to hospital discharge from the index procedure or within 7 days, whichever occurs first
A secondary performance endpoint defined as procedural success without procedural complications (death, above-ankle target limb amputation, thrombosis of the target lesion or TLR) prior to discharge.
Evaluated at discharge defined as immediately prior to hospital discharge from the index procedure or within 7 days, whichever occurs first
Secondary Angiographic Imaging Measures
Time Frame: 6 months
  • Subsegmental analysis: proportion of segments with binary restenosis (DS > 50%)
  • Subsegmental analysis: Mean LLL of all segments; mean %DS of all segments.
  • TVAL%
6 months
Wound healing
Time Frame: 1, 6, 12, 24, and 36 months

A secondary wound measure defined as investigator reported status of each index wound in comparison to baseline.

Descriptive categories to be captured on case report forms (CRFs): 1) Improved 2) Unchanged 3) Worse 4) Healed/Complete Closure. Note: New wounds (appearing at any time after index procedure) are identified and tracked in similar fashion as index wounds, adopting the initial evaluation & images as "baseline" for future comparisons.

1, 6, 12, 24, and 36 months
Wound Ischemia, foot infection (WifI) Classification
Time Frame: 1, 6, 12, 24, and 36 months
A secondary wound measure defined as investigator-reported granular descriptors of Wound, Ischemia, and Foot Infection.
1, 6, 12, 24, and 36 months
