Outcome Measures
Primary Outcomes (1)
Percentage of Subjects With a Sperm Concentration < 15 Million Per mL by Treatment Week 26
Percentage of Subjects with a Sperm Concentration \< 15 million per mL by Treatment Week 26. Sperm concentration was calculated as measure of the number sperm per milliliter of semen. Duplicate semen samples were collected. The average of the 2 samples were used as the value for that scheduled collection period.
Up to 26 weeks
Secondary Outcomes (10)
Percentage of Participants Who Entered the Observation Period and Did Not Return to Within 15% of Baseline Sperm Concentration or Above During the 52-Week Observational Period
Up to 52 weeks after the Treatment Period
Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Sperm Concentration
From Week 0 up to Treatment Period Week 26 and Observation Period Week 52
Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Sperm Motility
From Week 0 up to Treatment Period Week 26 and Observation Observation Week 52
Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Sperm Morphology
From Week 0 up to Treatment Period Week 26 and Observation Period Week 52
Change From Baseline up to Treatment Period Week 26 and Observation Period Week 52 in Semen Volume
From Week 0 to up to Treatment Period Week 26 and Observation Period Week 52

Eligibility Criteria
You may qualify if:
- Males 30 to 75 years of age
- Type 1 or 2 diabetes and receiving treatment with at least one anti-hyperglycemic medication and angiotensin-converting enzyme inhibitors (ACEi)/angiotensin receptor blockers (ARB) (renin-angiotensin system \[RAS\] inhibitor)
- Estimated Glomerular Filtration Rate (eGFR) equal to or greater than 35 mL/min/1.73 m\^2 with the Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) Formula and Urine Albumin-to-Creatinine Ratio (UACR) equal to or greater than 30 and less than 5,000 mg/g creatinine.
- Able to provide a semen specimen at the required intervals.
- Baseline sperm concentration equal to or greater than 30 million per mL.
You may not qualify if:
- Treatment with hormone suppressive agents or cancer chemotherapy within the 6 months prior to the initial screening visit or planned during the study.
- History of severe peripheral edema or facial edema unrelated to trauma or history of myxedema in the prior 4 weeks prior to screening.
- History of pulmonary hypertension, pulmonary fibrosis or any lung disease requiring oxygen therapy.
- Documented diagnosis of heart failure, previous hospitalization for heart failure or current or constellation of symptoms (dyspnea on exertion, pedal edema, orthopnea, paroxysmal nocturnal dyspnea) felt to be compatible with heart failure, that was not explained by other causes, and for which there was a change in medication or other management directed at heart failure.
- Currently receiving or has received hormone replacement therapy within 6 months prior to screening.
