Glucagon: the component that distinguishes a triple agonist from a dual one

Published 24 October 2026 · REVIVE LAB UAE Research Desk · 5 min read
Glucagon raises hepatic glucose output, which is why adding its activity to an anti-diabetic agent looks paradoxical. It also increases energy expenditure and reduces hepatic fat, which is why the discovery paper included it — on the premise that the incretin components would offset the glucose effect while the energy and liver effects remained.

What glucagon does

Secreted by the pancreatic alpha cell when glucose is low, glucagon acts on the liver to release glucose. It also increases energy expenditure, promotes lipid oxidation and reduces hepatic fat, effects documented in physiology long before any agonist was designed around them.

The glucose-raising effect is the one that made glucagon receptor agonism seem contrary to the goal of a metabolic drug.

The counterintuitive design

The 2022 paper's rationale is that incretin activity would counterbalance glucagon's effect on glucose, leaving its effect on energy expenditure and the liver. In diet-induced obese mice the glucagon component was associated with increased energy expenditure, and the phase 2 trials recorded glycaemic improvement rather than deterioration.

That is the empirical answer to the paradox: in this molecule at these receptor ratios, the net effect on glucose was favourable.

What the glucagon component is credited with

The magnitude of hepatic fat reduction in the Nature Medicine substudy is discussed in relation to glucagon receptor activity, with the authors clear that the design cannot separate it from the effect of weight loss. The same attribution limit applies to energy expenditure in people, which the phase 2 trials did not directly measure.

Mechanistic attribution in humans is therefore inferred from animal work and from the compound's design, not demonstrated in the trials.
