Study Details

Study Description

Brief Summary

The objective of this single arm interventional study is to determine if renal denervation performed in the distal main and first order branch renal arteries is as effective in reducing blood pressure as the procedural approach used in the SPYRAL HTN-OFF MED clinical study.

Arms and Interventions

Arm Intervention/Treatment
Experimental: Renal Denervation

Renal angiography and Renal Denervation (Symplicity Spyral™ multi-electrode renal denervation system)

  • Outcome Measures

    Primary Outcome Measures

    1. Change in systolic blood pressure (SBP) from baseline as measured by 24-hour Ambulatory Blood Pressure Monitoring (ABPM) [From baseline to 3 months post-procedure]

    Secondary Outcome Measures

    1. Change in systolic blood pressure (SBP) from baseline as measured by 24-hour Ambulatory Blood Pressure Monitoring (ABPM) [From baseline to 12 months post-procedure]

    2. Change in office systolic blood pressure [From baseline to 12 months post-procedure]

    3. Change in office diastolic blood pressure [From baseline to 12 months post-procedure]

    4. Change in office diastolic blood pressure baseline as measured by 24-hour ABPM [From baseline to 12 months post-procedure]

    5. Incidence of achieving target office BP [From baseline to 12 months post-procedure]

    6. Comparison of BP reduction pattern over 24 hours of ABPM [From baseline to 12 months post-procedure]

    7. Procedural characteristics (e.g. Procedure time, contrast media usage, etc.) [Baseline]

    8. Acute and chronic safety by evaluating incidence of Major Adverse Events [From baseline to 12 months post-procedure]

    9. Incidence of Myocardial Infarction [From baseline to 12 months post-procedure]

    11. Incidence of Renal artery re-intervention [From baseline to 12 months post-procedure]

    12. Incidence of Major bleeding according to TIMI definition [From baseline to 12 months post-procedure]

    13. Incidence of Increase in serum creatinine >50% [From baseline to 12 months post-procedure]
