Study summary

Low testosterone is a condition that occurs when the body is unable to produce sufficient quantities of testosterone. The medical name for low testosterone is hypogonadism. Hypogonadism can be caused by many factors. Symptoms include: decrease in libido, lack of energy and mood swings. The goal of testosterone replacement therapy is to return testosterone levels to the normal range and relieve symptoms.

The purpose of this study is to evaluate the ability of TSX-002, which is testosterone provided in easy to swallow capsules, to maintain serum (blood) testosterone levels within the normal range in hypogonadal men. This will be determined by blood sampling at specified times during the study. The study is also intended to evaluate the tolerability of TSX-002, which will be taken orally twice per day for 15 days. In addition, the study is intended to determine a dosing regimen(s) that achieves testosterone levels within the normal range. Related Outcome Measures will be reported for Parts 1, 2, and 4.

A portion of the study (Part 3) to also assess the effect of a high-calorie, high-fat meal on the single dose pharmacokinetic exposure of TSX-002. Related outcome measures to be reported for Part 3.

  • Men over the age of 18 years with a (BMI) \< 39.0 kg/m2 and weighing ≥ 55 kg
  • levels at screening and baseline > 12.5 g/dL
  • Testosterone treatment not
  • No evidence of suspected reversible hypogonadism

Exclusion criteria

Exclusion Criteria:

-

Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Hemoglobin (Hb)

The protein in red blood cells that carries oxygen. A low level is anaemia, which can cause tiredness and breathlessness. Measured in g/dL or g/L (9 g/dL is 90 g/L).

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Washout period

A planned gap after a treatment, so that its effects can lessen before the study treatment or a study assessment. Ask the study team and the doctor who prescribed it before changing any medicine.
