E.3 | Principal inclusion criteria |
Prior to run-in period 1. Subject has provided written informed consent 2. Male or female subject, aged ≥18 and ≤80 years at time of enrollment 3. Subject is taking 2-5 antihypertensive medications (labeled for hypertension) at time of enrollment, and is willing to adhere to a stable (no change) medication regimen during the 4-week run-in period and 3 months post-procedure. Antihypertensive medications must be as follows: • Two of the antihypertensive medications must be at least at 50% of their maximally labelled dose prior to the planned procedure • In subjects on 2 medications, one should be an ACE inhibitor or ARB, except where subjects have documented intolerance to each of these drug classes. • All subjects must currently be taking, or have documentation that they failed or cannot tolerate, a diuretic • In the case of the thiazide agents hydrochlorothiazide and chlorthalidone, doses should be 25 mg daily, reflecting the usual maximum doses in contemporary medical practice when these diuretic agents are used in combination treatment.In countries where thiazide like agents are used in line with current local prescribing practice, these agents should also be administered at the usual maximum dose in contemporary medical practice when used in combination treatment. • For subjects on 2 non-diuretic antihypertensive medications, because they either failed or have been unable to tolerate a diuretic, the 2 medications should consist of any of the classes of antihypertensive agents listed below, with the preferred choice of an ACE inhibitor or ARB and a CCB. In the latter case, if both ACE inhibitor/ARB and CCB are contraindicated or not tolerated, such reasons must be documented. Note: The following classes of antihypertensive agents that would count towards the minimum number of agents are: ACE inhibitors, ARBs, CCBs, thiazide diuretics, loop diuretics, aldosterone antagonists, beta-blockers, centrally active agents, alpha receptor blockers, direct vasodilators, direct renin inhibitors and hydralazine. 4. Subject meets blood pressure criteria at time of enrollment and prior to the 4-week run-in period: has 3 office blood pressure measurements with a mean office SBP of ≥150 mmHg and ≤180 mmHg, AND a mean office DBP ≥90 mmHg. 5. Investigator judges that the subject can be managed safely during the 4-week run-in period and 3 months post-procedure period without any changes to their current antihypertensive medication regimen 6. Female subjects of childbearing potential must agree to use acceptable methods of contraception, from the time of informed consent through to the last follow-up visit 7. Subject agrees to have all study procedures performed and is able and willing to comply with all study follow-up visits and protocol requirements
End of run-in period 8. Subject has maintained the same antihypertensive medication regimen for at least 4 weeks (28 days) prior to the procedure 9. Subject meets blood pressure criteria: • Has 3 office blood pressure measurements with a mean office SBP of ≥150 mmHg and ≤180 mmHg AND mean office DBP ≥90 mmHg AND • Has a mean 24-hour ambulatory SBP of ≥135 mmHg and ≤170 mmHg with ≥70% valid readings (as determined by ABPM measurement device) |

Subject has a known hypersensitivity to the neurolytic agent 18. Subject has a known history of substance (drug) use or alcohol dependence, or lacks the ability to comprehend or follow instructions, or for any reason, in the opinion of the investigator, would be unlikely or unable to comply with study protocol requirements 19. Subject is being treated chronically (e.g. daily use) with NSAIDs, immunosuppressive medications, or immunosuppressive doses of steroids 20. Subject has a history of myocardial infarction, unstable angina pectoris, or stroke/transient ischemic attack (TIA) within 6 months prior to the planned procedure. 21. If female, subject is pregnant or lactating at the time of enrollment or planning to become pregnant during the trial time period. 22. Subject has any other acute or chronic condition that the investigator believes will adversely affect the ability to interpret the data or will prevent the subject from completing the trial procedures, or has a life expectancy of <12 months. 23. Subject is participating or has participated in another clinical study involving an investigational drug or investigational device within 30 days prior to enrollment or is scheduled to participate in another clinical study involving an investigational drug or investigational device during the course of this study 24.
