6. At screening, systolic blood pressure =150 mmHg and diastolic blood pressure =100 mmHg.
7. Women of childbearing potential (WOCBP) must agree to the use of two forms of contraception.
Inclusion Criteria for Open-Label Extension Period:

4. WOCBP, beginning at menarche, must agree to the use of 1 highly reliable (ie, can achieve a failure rate of <1% per year) method of contraception from 7 days prior to the first dose of study medication until 90 days after the last dose of study medication (including open-label sparsentan). One additional barrier method must also be used during sexual activity, such as a diaphragm or diaphragm with spermicide (preferred), or male partner’s use of male condom or male condom with spermicide (preferred), from the Week 114 visit until 90 days after the last dose of study medication.
