A Study of Atrasentan on Reducing Albuminuria in Type 2 Diabetic Nephropathy Treated With Renin-Angiotensin System Inhibitors
A Phase 2a, Prospective, Randomized, Double-blind, Placebo-controlled Multicenter Study to Evaluate the Safety and Efficacy of Atrasentan on Reducing Albuminuria in Type 2 Diabetic Nephropathy Subjects Who Are Currently Being Treated With an Renin-Angiotensin System Inhibitor
The study objective is to investigate the effects of three low doses of atrasentan on urinary albumin/creatinine ratio (UACR) levels in subjects with Type 2 diabetic nephropathy.
Patients with Type 2 diabetes with nephropathy must be receiving a renin-angiotensin system inhibitor, such as an Angiotensin converting enzyme inhibitor (ACEi) or an Angiotensin II Receptor Blocker (ARB) for participation in this study. ACEi and ARB treatment are the standard of care for the management of proteinuria in Chronic Kidney Disease (CKD) patients.

Description
Inclusion Criteria:
- 1.Subject is >= 18 years old.
- 2.Subject has voluntarily signed and dated an informed consent form, approved by an Institutional Review Board (IRB)/Independent Ethics Committee (IEC), after the nature of the study has been explained and the subject has had the opportunity to ask questions. The informed consent must be signed before any study-specific procedures are performed.
- 3.Subject has Type 2 diabetes and has been treated with at least one anti-hyperglycemic medication within the 12 months prior to the Screening Phase.
- 4.Subject has been receiving a stable dose (i.e., same type and regimen) of angiotensin-converting enzyme inhibitors (ACEi) and/or angiotensin receptor blocking agents (ARB) for at least 2 months prior to the Screening Phase.
- 5.If female, subject must be not of childbearing potential, defined as postmenopausal for at least 1 year or surgically sterile (bilateral tubal ligation, bilateral oophorectomy or hysterectomy). The reason for non-childbearing potential must be specified in the subject's eCRF.
- 6.If male, subject must be surgically sterile or if sexually active and of childbearing potential, the site must document the lack of desire for future procreation and subject must agree to use a condom and a second reliable barrier of contraception from the Screening Visit through two months following completion of their participation in the study.
7.For entry into the Treatment Phase the subject must satisfy the following criteria based on Screening laboratory values:
- a.Estimated GFR > 20 mL/min/1.73 m2 by simplified MDRD formula
- b.UACR between 100 and 3000 mg/g as determined at the initial Screening visit or by the mean of the 2 morning void urine specimens obtained prior to the second Screening visit.
- c.Serum albumin > 3.0 g/dL.

- 9.Subject has a history of an allergic reaction or significant sensitivity to atrasentan or its excipients.
- 10.Subject has a history of a chronic gastrointestinal disease, which in the Investigator's opinion may cause significant GI malabsorption.
- 11.Subject has a history of secondary hypertension (i.e., renal artery stenosis, primary aldosteronism or pheochromocytoma).
- 12.Subject has poorly controlled hypertension (systolic blood pressure ≥ 160 mmHg and or diastolic blood pressure ≥ 90 mmHg) or hypotension (systolic blood pressure <= 90 mmHg).
- 13.Subject has significant comorbidities (e.g., advanced malignancy, advanced liver disease) with a life expectancy less than 1 year.
- 14.Subject is expected to receive an increased dose of current RAAS inhibitor (ACEi, ARB, renin or aldosterone inhibitor) during the course of the study. Conversions from one product to another (e.g., ACEi to ARB) must be at equivalent doses.
15.Subject has clinically significant coronary artery disease (CAD) within 3 months prior to the Screening Period, defined as one of the following:

- 20.Subject has received any investigational drug within 30 days prior to study drug administration.
- 21.For any reason, subject is considered by the Investigator to be an unsuitable candidate to receive atrasentan oral solution or is put at risk by study procedures
