Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The trial studies the efficacy of subcutaneous (SQ) testosterone compared to intramuscular (IM) testosterone therapy during the first 6 months of pubertal induction in transgender male adolescents. Describes rate of adverse effects, masculinizing effects and quality of life while receiving testosterone. Evaluates clinic utilization required for testosterone therapy.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Objectives:

1. Determine the efficacy of SQ testosterone compared to IM testosterone therapy. Hypothesis: SQ testosterone is equally efficacious to IM testosterone in achieving mid-pubertal testosterone levels and masculinizing physical changes in transgender male adolescents after 6 months.
2. Determine the rate of adverse reactions of SQ and IM testosterone during the first 6 months of treatment.

Hypothesis: SQ testosterone results in equal or fewer adverse reactions than IM testosterone.
3. Evaluate quality of life (QOL) and satisfaction of injection technique for SQ and IM testosterone.

Hypothesis: Subjects receiving SQ testosterone will report equal or superior quality of life and satisfaction with injection technique compared to IM testosterone as SQ is less painful and easier to administer at home.
4. Evaluate and compare the number of clinical visits required for testosterone injections by transgender male patients receiving SQ and IM therapy.

Hypothesis: Subjects using SQ testosterone will have fewer clinic visits than those using IM testosterone. This may impact healthcare-related costs.

Study Outline:

6 month study consisting of three study visits at baseline, 3 months and 6 months. Optional cross over of injection modality from 6-9 months. At each visit subjects complete blood work and questionnaires to determine testosterone peak and trough levels as well as biochemical adverse effects, quality of life, masculinizing effects and medication experience.
