Clinical Trial Summary

This study in being conducted in men who have low testosterone and chronic kidney disease. The investigators will evaluate the effects of an oral testosterone preparation, JATENZO, on testosterone levels and hemoglobin (red blood cells).

Description:

- Purpose. The purpose of this research is to find out if JATENZO will help increase testosterone levels in men with hypogonadism and chronic kidney disease, determine if there is any improvement in testosterone levels, hemoglobin (red blood cells), muscle strength, lean mass and sexual function. - The dug will be daily for 6 months. Study Procedures. Every 2-4 weeks, the study participant will come in person for a research visit. Investigators will collect a blood sample at certain visits, do a brief physical exam, and obtain vital signs such as height, weight, blood pressure. The study also involves completing questionnaires, measuring body composition by a scan and testing muscle strength. The dose of JATENZO may be adjusted based on the testosterone levels.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Testosterone concentrations	Testosterone concentrations in serum measured multiple times during the study	6 months
Secondary	Hemoglobin	blood test	6 months
Secondary	muscle strength	Hand-grip strength will be measured by a quantitative handgrip dynamometer in the dominant arm. Mean of three consecutive measurements will be used.	6 months
Secondary	Lean mass	measured by DEXA scan	6 months
Secondary	sexual function	Psychosexual daily questionnaire for 7 consecutive days will be used. The questionnaire covers three different domains: 1) sexual desire, enjoyment, and performance; 2) sexual activity score; and 3) mood. Sexual desire (question 1) and sexual enjoyment (question 2) will be rated on a 7-point Likert-type scale from 0 to 7, with 0 indicating none and 7 indicating very high. Sexual performance will be assessed by % full erection and satisfaction with erection (questions 5 and 6). Sexual activity (question 4) will be assessed using a checklist format. The value will be recorded as 0 (none) or 1 (any) for analysis. Higher score indicates higher activity; maximum score on this item is 12. Each mood parameter (question 3) will also be assessed on the 7-point Likert scale.	6 months
