The primary endpoint of the diabetes trial, explained

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Glucose attaches non-enzymatically to haemoglobin in proportion to its concentration, and red cells live about 120 days, so the fraction of glycated haemoglobin reflects average glucose over roughly the preceding three months. It is the standard primary measure in glycaemic trials. It does not capture day-to-day variability or hypoglycaemia, which are measured by other means.

The chemistry

Glucose reacts with the N-terminal valine of the haemoglobin beta chain to form a stable adduct. The reaction is slow and non-enzymatic, so the amount of adduct in a red cell reflects the glucose it has been exposed to over its lifetime. Measuring the glycated fraction in a blood sample therefore integrates glucose over the red-cell lifespan.

The result is reported as a percentage or in standardised units, and assays are calibrated internationally.

Why it is the primary endpoint

It is stable, requires no fasting, is unaffected by a single meal, and correlates with long-term complications in large epidemiological studies. Those properties make it the measure regulators accept for glycaemic efficacy, and it was the primary endpoint in the Lancet 2023 retatrutide trial.

The trial reported dose-dependent reductions at 24 and 36 weeks, exceeding the active comparator in the higher groups.

What it misses

Variability — the same average can arise from stable or widely swinging glucose. Hypoglycaemic episodes, which are counted separately. And it is affected by conditions that alter red-cell lifespan. Trials report fasting glucose and hypoglycaemia alongside it for these reasons.

Retatrutide is supplied by REVIVE LAB UAE as an investigational research material for laboratory use only, with identity by mass spectrometry and purity by HPLC for the batch. It is not approved for any use anywhere, and no dosing, administration or protocol guidance is provided.
