入选标准

  • 1. Male and female patients 18 to 65 years of age included, with a diagnosis of
  • hypertension and with abdominal obesity (elevated waist circumference, = 102 cm in men and = 88 cm in women)
  • 2. Systolic and diastolic blood pressure and pulse rate will be assessed after the patient has rested for at least five (5) minutes. Vital signs should be within the following ranges:
  • Patients with history of treated hypertension: msSBP/msDBP < 160/100 mmHg and = 135/85 mmHg at baseline
  • Patients who are newly diagnodes (untreated): msSBP/msDBP =135/85 mmHg and a msSBP/msDBP< 160/100 mmHg at screening, predose, and baseline.
  • All blood pressure measurements at other time-points should be assessed with the patient being in sitting position, unless stated otherwise in the protocol design, and utilizing the same arm for each determination.
  • 3. Female patients of child-bearing potential must use highly effective contraception.
  • Total abstinence at the discretion of the investigator in cases where the age,
  • career, lifestyle, or sexual orientation of the patient ensures compliance. Periodic
  • abstinence (e.g., calendar, ovulation, symptothermal, post-ovulation methods),
  • withdrawal and double-barrier methods are not acceptable methods of
  • contraception. Reliable contraception should be maintained throughout the study: the premenopausal femal subjects must be instructed not to change oral contraceptive brand or dose and the investigator must try to have the biomarker samples drawn at the same 1 to 3 days in their contraceptive package.
  • Postmenopausal women must have no regular menstrual bleeding for at least 1
  • year prior to inclusion. Postmenopausal women using hormonal replacement therapy are not allowed to take part in the study. Surgical sterilization procedures or hysterectomy must be
  • supported with clinical documentation made available to the sponsor noted in the
  • Relevant Medical History / Current Medical Conditions section of the CRF.
  • 4. Body mass index (BMI) must be between 30 and 36. For instructions and tables
  • see Appendix 3.
  • 5. Able to communicate well with the investigator, to understand and comply with the
  • requirements of the study. Understand and sign the written informed consent.
  • 6. Patient information and consent forms generated by the investigator must be
  • approved by the sponsor prior to submission to the Ethics Committee
  • (EC)/Institutional Review Board (IRB). A copy of the patient information and
  • consent forms approved by the EC/IRB must be forwarded to the sponsor prior to
  • study initiation.
  • 7. The INR (international normalized ratio) must be between the local laboratory
  • normal ranges.
  • Are the trial subjects under 18? no
  • Number of subjects for this age range:
  • F.1.2 Adults (18-64 years) yes
  • F.1.2.1 Number of subjects for this age range
  • F.1.3 Elderly (>=65 years) no
  • F.1.3.1 Number of subjects for this age range
