Study summary

Primary Objective:

To assess in overweight to obese subjects the change in sleep energy expenditure after repeated subcutaneous (SC) doses of SAR425899.

Secondary Objectives:

  • To assess the change in resting, basal and total daily energy expenditure.
  • To assess the change in respiratory quotient, fat, protein and carbohydrate oxidation.
  • To assess the change in body composition and core temperature.
  • To assess the pharmacodynamic effects on fasting plasma glucose, biomarkers of lipid metabolism and glycated hemoglobin (HbA1c).
  • To assess the pharmacokinetic parameters for SAR425899 after repeated SC doses.
  • To assess the safety and tolerability.
Read the detailed description

Study duration is approximately 7-8 weeks including a screening period, a 19-day treatment period and an end-of-study visit 7 days after last dosing.

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

  • Overweight to obese male and female subjects.
  • 28 - 40 kg/m2.
  • 18 to 50 years of age
  • Fasting plasma glucose ≤125 mg/dL.
  • Glycated hemoglobine () ≤6.5%.
  • Obesity associated mild concomitant diseases allowed (eg, mild hypertension, mild hypercholesteremia, and hyperlipidemia).
  • No concomitant medication allowed except stable treatment with statins or antihypertensive drugs (except ß-blocker).
  • Females should be either , or, if perimenopausal should have a normal regular menstrual cycle and should start or continue stable treatment with a monophasic oral .

Exclusion criteria

Exclusion criteria:

  • Elevated liver enzymes, lipase, amylase, or calcitonin at screening.
  • Current participation in an organized diet / weight reduction program or clinical trial of weight control or weight loss attempt, plans for major changes in physical activities or significant change in body weight in the 2 months prior to screening.
  • Any condition possibly affecting gastric emptying or absorption from gastro-intestinal tract (eg, gastric surgery, gastrectomy, bariatric surgery, malabsorption syndromes, gastroparesis, abdominal surgery other than appendectomy or hysterectomy.

The above information is not intended to contain all considerations relevant to a patient's potential participation in a clinical trial.

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.

HbA1c

A blood test of average blood sugar over the past two to three months, given as a percentage or in mmol/mol. 6.5% (48 mmol/mol) or more is the usual threshold for diabetes, normally confirmed by a second test.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

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 Apr 2018 to primary completion in Dec 2018, 8 months.

Of 453 industry-sponsored phase 1 interventional studies under Diabetes Mellitus, Type 2, half reached primary completion within 5 months of starting (the median), counting those still running; a quarter within 2 and three quarters within 11. This study's 8 months is above that.

Counting every sponsor, half of 515 studies reached it within 6 months; a quarter within 2 and three quarters within 14.

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 Apr 25, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
