This study compared the safety and efficacy of compounded and market brand testosterone pellets for testosterone therapy in men with testosterone deficiency. The results showed similar serum testosterone levels and adverse event rates between the two groups. Therefore, compounded testosterone pellets are a noninferior option for testosterone therapy in men with testosterone deficiency when compared to market brand pellets.
Background: Testosterone deficiency (TD) is a prevalent condition, especially in men & GE;45 years old, and testosterone therapy (TTh) can improve the quality of life in these patients.Aim: To evaluate the safety profile of compounded subcutaneous testosterone pellets and to compare the efficacy between compounded and market brand testosterone pellets for TTh: E100 (Empower Pharmacy) and Testopel (Food and Drug Administration approved), respectively.Methods: This was a prospective, phase 3, randomized, noninferiority clinical trial. We enrolled 75 men diagnosed with TD and randomized them 1:1 to a market brand group and a compounded pellet group. The patients were implanted with their respective testosterone pellets: Testopel (10 pellets of 75 mg) and E100 (8 pellets of 100 mg).Outcomes: We evaluated adverse events after implantation and followed men at 2, 4, and 6 months for morning laboratory levels (prior to 10 AM): serum testosterone, estradiol, hematocrit, and prostate-specific antigen.Results: After randomization, 33 participants were enrolled in the Testopel arm and 42 in the E100 arm. Serum testosterone levels were similar between the groups at 2, 4, and 6 months, with most men (82%) dropping to <300 ng/dL by the end of the trial. Adverse events were also similar, such as elevations in prostate-specific antigen, estradiol, and hematocrit. Most dropouts were related to persistent TD symptoms and serum testosterone <300 ng/dL, with similar rates between the groups in the study.Clinical Implications: Men treated with Testopel and E100 pellets had comparable serum testosterone levels and similar adverse event rates,Strengths and Limitations: Strengths include the prospective, randomized, single-blinded study design and adequate follow-up. LimitationsConclusion: E100 compounded testosterone pellets are a noninferior option of TTh as compared with Testopel for men presenting with TD.
