Abstract

Experimental fibroblast growth factor 21 (FGF21) analogs can improve lipid profiles in patients with metabolic diseases. However, their effects on markers of insulin sensitivity appear to be minimal, potentially because of insufficient exposure. Systemic drug levels vary from sub-pharmacological to demonstrating pharmacodynamic effects but with dose-limiting adverse events. Here we report results from a phase 1 multiple ascending dose study of AKR-001, an Fc-FGF21 fusion protein engineered for sustained systemic pharmacologic exposure, in individuals with type 2 diabetes. With a half-life of 3-3.5 days, the peak-to-trough ratio under steady-state conditions is approximately 2 following QW dosing. AKR-001 appears to demonstrate pharmacodynamic effects on serum markers of insulin sensitivity and acceptable tolerability up to and including 70 mg QW. Positive trends in lipoprotein profile, including triglycerides, non-high-density lipoprotein (non-HDL) cholesterol, HDL-C, and apolipoproteins B and C3 are consistent with other FGF21 analogs. AKR-001's clinical profile supports further evaluation as a treatment for metabolic diseases.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • All FGF21 analogues consistently have a pronounced ability to decrease plasma triglyceride levels, in many cases by as much as ~70%.

    “all analogues consistently have a pronounced ability to decrease plasma triglyceride levels, in many cases by as much as ~70% (refs. 81,87–91).”

    From Metabolic messengers: FGF21 (2021) · cites this paper as [88]

  • Effects of different FGF21 compounds on glucose homeostasis and insulin sensitivity vary: some do not significantly affect insulin sensitivity, while others significantly increase it in people with type 2 diabetes.

    “some compounds do not significantly affect insulin sensitivity81, while others significantly increase insulin sensitivity in people with type 2 diabetes87,88.”

    From Metabolic messengers: FGF21 (2021) · cites this paper as [88]

  • The magnitude of glucose-lowering effects of FGF21 analogues is clearly lower in humans than rodents.

    “the magnitude of the glucose-lowering effects of FGF21 analogues is clearly lower in humans than rodents81,87–91, perhaps because of differences in brown adipose tissue metabolism between species65.”

    From Metabolic messengers: FGF21 (2021) · cites this paper as [88]

  • Two other FGF21 analogues AKR-001 and pegbelfermin have not been found to significantly decrease body weight in people with obesity or type 2 diabetes.

    “two other FGF21 analogues, AKR-001 (also known as efruxifermin)88 and pegbelfermin89,90, have not been found to significantly decrease body weight in people with obesity or type 2 diabetes.”

    From Metabolic messengers: FGF21 (2021) · cites this paper as [88]

  • FGF21's triglyceride-lowering effects are mediated by altered adipose and liver metabolism: accelerated lipoprotein catabolism, suppression of postprandial lipolysis, decreased hepatic ER and oxidative stress, and increased beta-oxidation of lipids in the liver.

    “Pharmacological administration of FGF21 or FGF21 analogues exerts lipid-lowering effects through accelerated lipoprotein catabolism108, suppression of postprandial lipolysis in adipose tissues88, decreased hepatic endoplasmic reticulum and oxidative stress109,110, and increased beta-oxidation of lipids in the liver62”

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
