Terms in these criteria, in plain language(9)

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.

GFR and eGFR (kidney filtering)

GFR (glomerular filtration rate) is how much blood the kidneys filter each minute. It is usually estimated from a blood test — eGFR, by formulas such as CKD-EPI or MDRD — and some studies ask for it to be measured directly instead. Usually given in mL/min/1.73 m².

Check the method, the units and the minimum the study states. A value of 90 or above is in the normal-or-high range, but kidney damage can show in other tests too.

ALT and AST (liver enzymes)

Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.

Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.

ULN (upper limit of normal)

The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.

“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.

NYHA class (heart failure)

The New York Heart Association’s four classes of how much heart failure limits physical activity.

I
No limits: ordinary activity causes no undue tiredness or breathlessness.
II
Slight limits: comfortable at rest, ordinary activity causes symptoms.
III
Marked limits: comfortable at rest, less than ordinary activity causes symptoms.
IV
Symptoms even at rest; any activity makes them worse.

Studies set their own limit — many outside heart failure leave out class III–IV, while heart failure studies may ask for a particular class. Check the class this study names.

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).

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

What researchers measure

Primary outcomes

  1. Acute Insulin secretion

    Acute (first phase) insulin response (AIRg) to glucose will be calculated as the mean incremental responses above baseline (average of -20 and -10 and 0 minutes) to the samples drawn at 2, 4, 6, 8 and 10 minutes of the hyperglycemic clamp.

    Time frame: At baseline and after 4 weeks of study drug treatment

Secondary outcomes

  1. Second phase insulin secretion

    The mean incremental insulin levels between 60 to 90 minutes of hyperglycemic clamp

    Time frame: At baseline and after 4 weeks of study drug treatment

  2. Beta cell glucose sensitivity

    Beta cell glucose sensitivity will be calculated as increment of insulin secretion in 60-90 minutes of the clamp minus basal insulin divided by glucose change in the same period

    Time frame: At baseline and after 4 weeks of study drug treatment

  3. Glucagon-like peptide -1 (GLP-1)

    GLP-1 secretion Area under the curve (0-270 minute during hyperglyemic- OGTT clamp study)

    Time frame: At baseline and after 4 weeks of study drug treatment

  4. Glucagon

    Glucagon area under the curve (0-270 minute) during hyperglyemic- OGTT clamp

    Time frame: At baseline and after 4 weeks of study drug treatment

  5. Incretin effect

    Difference between the post prandial (100-270min) and preprandial (60-90min) C peptide response

    Time frame: At baseline and after 4 weeks of study drug treatment
