Fast-Acting Insulin Aspart and Insulin Pump Settings
February 12, 2021 updated by: Kirsten Nørgaard
Fast-Acting Insulin Aspart and Insulin Pump Settings: THE FAST PUMP SETTING STUDY
To clarify the role of fast-acting insulin aspart (Fiasp) in insulin pump-treated type 1 diabetes more research is needed.
The aim of this study is twofold:
- to compare the effects of Fiasp and Iasp in adults with type 1 diabetes who are using insulin pump and CGM and who are attending a diabetes out-patient clinic with extensive expertise in insulin pump and CGM therapy.
- to determine differences in insulin pump settings when insulin pumps are optimally adjusted to each of the two insulin types.
