ACOART Paclitaxel SVD:Paclitaxel Coated Coronary Balloon Catheter in Treatment of Coronary Small Vessel Diseases

Not Applicable

Recruiting

• Conditions: Coronary Disease
• Interventions: Device: test DCB; Device: RESTORE DCB

• Registration Number: NCT04626687
• Lead Sponsor: Acotec Scientific Co., Ltd

Brief Summary

The purpose of the trial is to determine whether DCB made by Acotec Scientific is not inferior to RESTORE DEB made by CARDIONOVUM GmbH in treatment of small vessel coronary disease.

Detailed Description

This is a prospective, multi-center, randomized-controlled clinical trial to verify the efficacy and safety of DCB made by Acotec Scientific versus RESTORE DEB in treatment of small vessel coronary disease. And the primary endpoint is angiographic restenosis at 9 months post-procedure.

Inclusion Criteria

• 18 to 80 years of age

• Pregnant or nursing subjects and those who plan pregnancy in the period up to 1 year following index procedure.
• Subject is currently participating in another investigational drug or device study that has not yet completed its primary endpoint.
• Subject unsuitable for study according to the investigator due to the investigator due to other reasons related to diseases.
• Angiography exclusions:Target lesion: Total occlusion lesion (TIMI 0), heavy calcified lesion that cannot be successfully dilated, bifurcation lesion (side branch ≥ 2.0 mm in diameter), restenosis lesion, thrombotic lesion, or left main disease;Non-target lesion: More than 2 non-target lesions or non-target lesion cannot be successfully treated.
