- Patients need to be treated with an ACEI and/or ARB, for at least 3 months prior to ACTH treatment and have adequately controlled blood pressure (BP <130/75 mm Hg in >75% of the readings). Patients with documented evidence of >3 months treatment with maximal Ang II blockade, target BP (BP <130/75 mm Hg in >75% of the readings) and who remain with proteinuria >4.0g/24h may enter the ACTH phase of the study without the need to have the run-in/conservative phase of the study.
