Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • The must be signed before any study specific tests or procedures are done.
  • Healthy male subject.
  • Age: 18 to 45 years (inclusive) at the screening.
  • (BMI): above/equal 18 and below/equal 29.9 kg/m2.
  • Ability to understand and follow study-related instructions.

Exclusion criteria

Exclusion Criteria:

  • Pre-existing diseases for which it can be assumed that the absorption, distribution, metabolism, elimination and effects of the study drugs will not be normal.
  • Subjects with thyroid disorders as evidenced by assessment of thyroid stimulating hormone (TSH) levels outside the normal reference range at screening.
  • Regular use of medicines.
  • Smoking more than 10 cigarettes daily.
  • Systolic blood pressure below 100 or above 145 mmHg (at screening).
  • Diastolic blood pressure below 50 or above 90 mmHg (at screening).
  • Heart rate below 50 or above 90 beats/ min (at screening).
Terms in these criteria, in plain language(2)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Aug 2017 to primary completion in Apr 2019, 20 months.

Of 77 industry-sponsored phase 1 interventional studies under Renal Insufficiency, Chronic, half reached primary completion within 7 months of starting (the median), counting those still running; a quarter within 5 and three quarters within 16. This study's 20 months is above that.

Counting every sponsor, half of 109 studies reached it within 12 months; a quarter within 5 and three quarters within 27.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 19, 2019, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
