Is this trial a fit for you?

Likely a good fit

What this trial studies

This research evaluates the effects of an oral testosterone preparation, JATENZO, in men suffering from low testosterone levels and chronic kidney disease. The study aims to determine if JATENZO can improve testosterone levels, hemoglobin, muscle strength, lean mass, and sexual function over a period of six months. Participants will attend in-person visits every 2-4 weeks for blood samples, physical exams, and questionnaires, with adjustments to the testosterone dose based on individual levels.

Why it matters

Potential benefit: If successful, this treatment could significantly improve the quality of life for men with hypogonadism and chronic kidney disease by enhancing testosterone levels and associated symptoms.

How similar studies have gone: Other studies have explored testosterone treatment in similar populations, showing promising results, but this specific approach with JATENZO is relatively novel.
