入选标准

  • 1) Individual is >=18 years of age at time of enrollment (consent)
  • 2) Individual is diagnosed with hypertension and has an average baseline office
  • systolic blood pressure >=140 mmHg (measured per Appendix B)
  • 3) >=7 days of valid pre-procedure HBP measurements within 30 days prior to the
  • procedure; consecutive days are preferred but not required (measured per
  • Section 9.5) Not applicable for the Continuation Cohort
  • 4) Individual agrees to have all study procedures performed and is competent
  • and willing to provide documented informed consent to participate in this
  • clinical study. Continuation Cohort must again meet this criterion at time of
  • SPYRAL AFFIRM Consent
  • 5) Individual was initially randomized to the treatment arm and successfully
  • underwent the RDN procedure, in either the SPYRAL-PIVOTAL- SPYRAL -HTN-OFF MED
  • or SPYRAL HTN-ON MED study. Continuation Cohort only
  • 6) Individual has completed their 36- month visit and been exited from the
  • SPYRAL-PIVOTAL- SPYRAL-HTN OFF MED or SPYRAL HTN-ON MED study. Continuation
  • Cohort only
  • 7) Individual has a baseline office diastolic blood pressure >=90 mmHg (measured
  • per Appendix B)
  • 8) Individual has an average systolic baseline home blood pressure >=135 mmHg
  • (calculated using home blood pressure readings from the first 7 valid days
  • post-baseline).

排除标准

  • 1) Individual has renal artery anatomy that is ineligible for treatment
  • a) At least one main renal artery with a diameter of less than 3 mm or greater
  • b) Lacks a main renal arterial vessel that does not allow 4 simultaneous
  • quadrantic (4SQ) radio frequency ablations in the main renal artery or
  • equivalent (defined as 4SQ ablations in all branch vessels between 3mm and 8mm)
  • 2) Individual has >50% stenosis in any treatable vessels.
  • 3) Individual has a treatment area within 5mm of a segment in the renal artery
  • which contains any of the following:
  • a) Atheroma
  • b) Calcification, or
  • c) Renal artery stent
  • 4) Individual has a renal artery stent placed <3 months prior to procedure
  • 5) Individual has undergone prior renal denervation
  • 6) Presence of fibromuscular dysplasia (FMD) (defined as visible beading of the
  • artery on angiography)
  • 7) Individual has untreated secondary cause of hypertension (either known or
  • suspected). Secondary cause does not include obstructive sleep apnea
  • 8) Individual has a documented condition that would prohibit or interfere with
  • ability to obtain an accurate blood pressure measurement using the
  • protocol-specified blood pressure monitors (e.g., upper arm circumference
  • outside cuff size ranges or arrhythmia that interferes with monitor*s pulse
  • sensing or prohibits an accurate measurement) Continuation Cohort must not meet
  • this criterion again at time of SPYRAL AFFIRM Consent.
  • 9) Individual has a documented confounding medical condition, which in the
  • opinion of the investigator, may adversely affect the safety of the participant
  • (e.g., individuals with clinically significant peripheral vascular disease, or
  • aortic aneurysm)
  • 10) Individual requires chronic oxygen support or mechanical ventilation other
  • than nocturnal respiratory support for sleep apnea (e.g. CPAP, BiPAP)
  • 11) Individual has an estimated glomerular filtration rate (eGFR) of <45
  • mL/min/1.73m2, using the 4 variable MDRD calculation (in mL/min per 1.73m2 =
  • 175 x SerumCr -1.154 x Age -0.203 x 1.212 (if subject is of African descent) x
  • 0.742 (if subject is female).
  • 12) Individual has had >= 1 episode(s) of orthostatic hypotension not related to
  • medication changes within the past year or has a reduction of SBP of >= 20 mmHg
  • or DBP of >=10 mmHg within 3 minutes of standing coupled with symptoms during
  • the screening process
  • 13) Individual is pregnant, nursing or planning to become pregnant during the
  • study. (Note: Pre-menopausal participants must have a negative serum or urine
  • human chorionic gonadotropin (hCG) pregnancy test prior to angiography)
  • Continuation Cohort must not meet this criterion again at time of SPYRAL AFFIRM
  • 14) Individual has polycystic kidney disease, unilateral kidney, atrophic
  • kidney, or history of renal transplant
  • 15) Individual has a history of narcotic drug abuse or is currently on
  • Methadone, and would be unlikely or unable, in the opinion of the investigator,
  • to comply with study follow-up requirements
  • 16) Individual has a history of bleeding diathesis (bleeding disorders such as
  • thrombocytopenia, hemophilia, significant anemia, or evidence of autonomic
  • dysfunction where imbalance of sympathetic and parasympathetic tone may alter
  • disease process in an unpredictable manner) or coagulopathy or will refuse
