Outcome measures
Primary outcome
To determine a pharmacokinetic profile of testosterone for all subjects in all
treatments by measuring:
• Cmin, Cmax, and tmax for the 12 hour interval.
• AUC0-12, and Cavg.
• The relative pharmacokinetic profile of three different formulations of
intranasal testosterone will be determined using the AUC0-12h and Cmax0-12h
corrected for the endogenous serum testosterone concentrations.
Secondary outcome
Safety
• DHT levels
• Vital Signs (Blood Pressure, Body Temperature, Respiratory Rate, Heart
Rate).
• Physical and otorhinolaryngological examination.
• Complete Blood Count: white blood count, hemoglobin and hematocrit.
• Clinical chemistry profile: Na/K, glucose, urea, creatinine, calcium,
phosphate, uric acid, total bilirubin, albumin, AST, ALT, ALP, GGT and CK.
• Urinalysis.
Background summary
Trimel BioPharma has developed an intranasal testosterone gel (TBS-1/1A) as a
hormone replacement therapy for the treatment of male hypogonadism. The nasal
mucosa offers an alternative route of administration that is not subjected to
the first pass metabolism, has high permeability, with rapid absorption into
the systemic ciruclation, producing high plasma levels similar to those
observed after intravenous administration. The advantages of intranasal
testosterone gel, compared to other modes of administration, include ease of
administration, lower amounts of testosterone and no transference of
testosterone to other family members.
Study objective
The purpose of the study is to determine the PK profile of three different
intranasal testosterone formulations.
Study design
This will be an open-label, balanced, randomized, crossover, three-group,
three-treatment, three-period, pharmacokinetic study in healthy adult male
subjects
Intervention
testosterone intranasal gel
Study burden and risks
The risk to the subject by participating in this study is considered to be
minimal. Testosterone replacement therapy is indicated for the treatment of
hypogonadism and TBS-1 has been administered to over 100 men with minimal side
effects. Participants may find the nasal endscopy and numerous blood draws
unplesant.
There is no direct benefit to subjects participating in this study as they are
healthy men. Subjects will be financially compensated for their participation.
