(071) NON-PROPRIETARY SUBCUTANEOUS TESTOSTERONE REPLACEMENT THERAPY FOR HYPOGONADAL MEN

Abstract Introduction Advancement in the treatment for male hypogonadism involves investigation into safer, less expensive, and more effective alternatives than currently available treatment modalities, with subcutaneous testosterone replacement therapy (SubQ TRT) offering an attractive solution to several patient concerns. Objective To assess the use of non-proprietary SubQ TRT as treatment for hypogonadal men and its effect on HCT, PSA, and patient satisfaction. Methods This is a retrospective chart review of 93 men, mean age 60.6 years, receiving SubQ TRT with a mean follow up length of 17.9 months (range 0-52 months). Patient data was collected prior to initiation of therapy and at subsequent visits. Serum testosterone, HCT, and PSA were determined through regular blood draws, and patient demographics, AUA Symptom Index (AUA SI), Sexual Health Inventory for Men (SHIM) Scores, and patient satisfaction were collected at patient visits or via patient communication through email and phone. Univariate analysis and paired t-tests were used to analyze study variables. Results 93 patients received SubQ TRT. Mean changes in total testosterone level (increased 125.77 ng/dL, p-value<0.001), hematocrit (increased 1.2%), PSA (increased 0.3 ng/dl), SHIM score (increased 0.9 points) and AUA symptom score (decreased 0.3 points) were calculated at the patients’ initial and follow up visits while on SubQ TRT. Sixty-eight (73%) patients had been on various combinations of TRT before switching to SubQ: IM, CC, Testopel, T-Gel, HCG, and Anastrozole. Patient satisfaction surveys were completed by 57 patients (61%), with 26 (78.9%) patients reporting satisfaction with SubQ TRT versus 28.1% with past forms of TRT. Patients reported SubQ TRT to be both easier (71.4%) and generally preferred (71.1%) over their previous form of TRT. Several patients stopped SubQ TRT including one patient with stroke. Lastly, a cost analysis using the average available GoodRx prices in the Chicagoland area showed that a 1-month supply of non-proprietary testosterone cypionate was $235.45 less than Xyosted (the only FDA-approved SubQ TRT for management of male hypogonadism). Conclusions Use of non-proprietary testosterone cypionate as TRT results in an elevation in serum testosterone with favorable side effect profiles and overall patient satisfaction.
