About this study

Official title: A Multicenter, Open Label, Variable Dose, Two Arm Pilot Paediatric Phase 1 PK Study to Evaluate Testosterone Nasal Gel (4.5% w/w) in Hypogonadal Boys

PK study to evaluate serum levels of testosterone post nasal delivery in two cohorts of hypogonadal boys.

Read the detailed description

ARM 1 - 10 prepubertal, 12-17 years old boys with no prior exposure to TRT will receive single dose of 5.5 mg on day one and single dose of 11 mg on day 2 with repeat blood draws to assess serum levels of testosterone and metabolites.

ARM 2 - 10 Tanner Stage 3, 12-17 years old boys on TRT with bone age >= 13 years will receive single dose of 11 mg on day one, and single dose of 11 mg in the morning and a second 11 mg dose in the afternoon on day 2 with repeat blood draws to assess serum levels of testosterone and metabolites.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Maximum plasma concentration (Cmax)

    Cmax for serum testosterone, serum DHT and serum estradiol

    Measured: 48 hours (approx)

  2. Area under the curve (AUC)

    AUC for serum testosterone, serum DHT and serum estradiol

    Measured: 48 hours (approx)

  3. Minimum serum concentration (Cmin)

    Cmin for serum testosterone, serum DHT and serum estradiol

    Measured: 48 hours (approx)

  4. Time to reach maximum plasma concentration (tmax)

    tmax for serum testosterone, serum DHT and serum estradiol

    Measured: 48 hours (approx)

Secondary outcomes (2)
  1. Incidence of Treatment-Emergent Adverse Events (Safety)

    Safety assessments will include adverse events, clinical laboratory measurements of serum testosterone, DHT and estradiol levels, and vital sign measurements. A phone call will be made 3 days after the patient leaves the clinic to collect any SAEs or AEs that may occur.

    Measured: 5 days

  2. Incidence of Treatment-Emergent Adverse Events (Tolerability)

    To include a adverse events that relate to tolerability and a patient and healthcare provider questionnaire on ease of use dispenser and gel administration

    Measured: 48 hours (approx)

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Testosterone Nasal Gel [Natesto] in people with Hypogonadism, run by Acerus Biopharma Inc. at 3 sites in United Kingdom.

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 12 inclusion and 13 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: stopped early, as of the sponsor's last update on 26 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 3 sites in United Kingdom. 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?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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 was stopped early (reason given: Lack of patients and commercial reasons). Results are not available in the source record.

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?

Maximum plasma concentration (Cmax) (time frame: 48 hours (approx)). The study lists 4 primary outcomes in all. 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 26 Oct 2023.
