About this study

Official title: Investigating the Efficacy of Subcutaneous Testosterone Compared to Intramuscular Testosterone in Gender Affirming Care of Transgender Male Adolescents

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.

Read the detailed description

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.

Being tested
Testosterone injection, PedsQL questionnarie, Masculinizing effects questionnaire, Medication experience questionnaire
Keywords
Gender affirming care

Questions about this trial

What is this clinical trial studying?

A Early Phase 1 study testing Testosterone injection, PedsQL questionnarie and Masculinizing effects questionnaire in people with Health Services for Transgender Persons and Transgender Persons, run by Oregon Health and Science University at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 3 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 3 Apr 2024. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Serum testosterone level (time frame: Two lab draws, before and after testosterone injection, drawn at 3 month and 6 month follow up). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Apr 2024.
