Eligibility Criteria

Check the participation requirements, including inclusion and exclusion rules, age limits, and whether healthy volunteers are accepted.

Inclusion Criteria

* Patient is an ambulatory male or female from 25 to 75 years old at the Screening Visit.
* Patient has type 2 diabetes diagnosed by a physician or nurse practitioner ≥6 months before the Screening Visit, has been on ≥1 antihyperglycemic medication for ≥12 weeks preceding the Randomization Visit, and has been on a stable regimen (ie, same drug and same dose) of ≥1 antihyperglycemic medication for ≥28 days preceding the Randomization Visit. (Modification of short-acting insulin throughout the Screening Period will not affect eligibility.)
* Patient has been on a stable regimen (ie, same drug and dose) of antihypertensive medications, which must include an angiotensin-converting enzyme inhibitor (ACEi) or an angiotensin receptor blocker (ARB), for ≥28 days preceding the Randomization Visit and is expected to remain on their regimen through the Follow-up Visit.
* Patient has the following:

1. Estimated glomerular filtration rate (eGFR) 30 to 75 mL/min/1.73 m2 by the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) creatinine equation (1) at the Screening and Baseline Visits
2. Urine albumin-to-creatinine ratio (UACR) \>200 mg/g at the Screening and Baseline Visits and \<5000 mg/g at Screening and Baseline Visits
3. Serum albumin \>3.0 g/dL at the Screening and Baseline Visits
4. Hemoglobin A1c (HbA1c) ≤11% at the Screening and Baseline Visits
5. Systolic blood pressure (BP) of 110 to 160 mm Hg at the Screening and Baseline Visits
* Women of childbearing potential must have a negative pregnancy test prior to randomization and must agree to use protocol-specified contraception from the Screening Visit through 60 days after the final dose of study drug.
* Male patients must be surgically sterile by vasectomy (conducted ≥60 days before the Screening Visit or confirmed via sperm analysis) or must agree to use protocol-specified contraception from the Screening Visit through 60 days after the final dose of study drug.

Exclusion Criteria

* Patient has a history of secondary hypertension (ie, renal artery stenosis, primary aldosteronism, or pheochromocytoma).
* Patient has a body mass index (BMI) \<20 or \>45 kg/m2 at the Screening Visit.
* Patient has a history of platelet dysfunction, hemophilia, von Willebrand disease, coagulation disorder, other bleeding diathesis, or significant, nontraumatic bleeding episode(s), such as from a gastrointestinal source.
* Patient has hepatic impairment defined as Child-Pugh A, B, C.
* Patient has significant comorbidities (eg, malignancy, advanced liver disease, pulmonary hypertension, pulmonary fibrosis, lung disease requiring supplemental oxygen) or other significant conditions that, in the Investigator's opinion, would limit the patient's ability to complete or participate in this clinical study; has been hospitalized for cardiovascular, renal, or metabolic cause in the 3 months before the Screening Visit; or has a life expectancy of less than 1 year.
* Patient has had prior dialysis, renal transplant, or planned renal transplant.
* Patient has clinically active, symptomatic, or unstable coronary artery or heart disease within the 3 months before the Screening Visit, defined as 1 of the following:

1. Hospitalization for myocardial infarction (MI), unstable angina, or heart failure
2. New-onset angina with positive functional study or coronary angiogram revealing stenosis
3. Coronary revascularization procedure
* Patient has a history of clinically significant hypersensitivity or allergies to any of the inactive ingredients contained in the active or placebo drug products.
* Patient has previously received IW-1973 in a study, or received an investigational drug during the 30 days or 5 half-lives of that investigational drug (whichever is longer) before the Screening Visit, or is planning to receive another investigational drug at any time during the study.
* Patient is taking specific inhibitors of phosphodiesterase 5 (PDE5), nonspecific inhibitors of PDE5 (including dipyridamole and theophylline), any supplements for the treatment of erectile dysfunction, riociguat, or nitrates or nitric oxide (NO) donors in any form. These medications and supplements are prohibited from 7 days before Randomization through the duration of the study.
* Patient is taking strong cytochrome P450 3A (CYP3A) inhibitors (eg, ketoconazole, indinavir, nelfinavir, ritonavir, saquinavir, clarithromycin, telithromycin, itraconazole, and nefazodone). These medications are prohibited 14 days before Randomization through the duration of the trial.
