Official title

A Prospective, Multicenter Clinical Trial to Evaluate the Safety and Effectiveness of the Single-Use Coronary Forward Intravascular Lithotripsy Catheter Combined With the Intravascular Lithotripsy Therapy Device for Pre-treatment of De Novo Calcified Stenotic Coronary Lesion

Overview

The FORWARD IVL trial is a Prospective, Multicenter Study conducted to assess the safety and effectiveness of the Single-Use Coronary Forward Intravascular Lithotripsy Catheter combined with the Intravascular Lithotripsy Therapy Device for the pre-treatment of calcified, stenotic de novo coronary artery lesions .

Detailed description

The approved IVL devices are based on balloon design, and the biggest limitation is the crossability, especially in the severe stenosis lesions.

Coronary Forward IVL Catheter allow the catheter to modify calcium in tight, difficult to cross lesions to increase the compliance of the vessel and allow further crossing of the device or additional treatment.

This trial consists of two parts:

Part 1 (RCT part): this part is a prospective, multicenter, randomized controlled, study in subjects with moderate-to-severe calcification.180 eligible subjects are planned to enroll .

Part 2 (Single-arm part):This part is a single-arm study in subjects with calcified lesions that are Chronic Total Occlusions (CTOs)(with minimum 30 subjects).

Interventions

  • Device Intravascular Lithotripsy
    study group will receive the investigational devices (Single-Use Coronary Forward Intravascular Lithotripsy Catheter combined with the Intravascular Lithotripsy Therapy Device) for calcified lesion pre-treatment.
  • Device Rotational Atherectomy
    control group will receive the control device (Coronary Rotational Atherectomy System)

Primary outcome measures

  • Rate of Device Success [Time frame: immediately after IVL intervention]
  • Freedom from Major Adverse Cardiovascular Events (MACE) within 30 days post-procedure [Time frame: 30-day after the procedure]
Secondary outcome measures (10)
  • Rate of Technical Success [Time frame: immediately after the procedure]
  • Rate of Angiographic Success [Time frame: Peri-procedural]
  • Rate of Procedural Success [Time frame: at discharge/up to 7 days after the procedure]
  • Incidence of serious angiographic complications [Time frame: immediately after the procedure]
  • Incidence of MACE [Time frame: during procedure, at discharge (up to 7 days after the procedure) ,180 days after the procedure]
  • Incidence of Target Lesion Failure [Time frame: during procedure, at discharge (up to 7 days after the procedure), 30 days after the procedure, 180 days after the procedure]
  • Incidence of Patient-Oriented Cardiovascular Endpoint [Time frame: during procedure, at discharge (up to 7 days after the procedure), 30 days after the procedure, 180 days after the procedure]
  • Incidence of Device Deficiencies [Time frame: immediately after the prcedure]
  • Excellent rate of device performance evaluation [Time frame: Immediately after the procedure]
  • Incidence of Adverse Events and Serious Adverse Events [Time frame: through study completion, 180 days after the procedure]
