About this study
Acute, double-blinded, randomized, cross-over cafestol intervention study with sixteen participants with T2D participating in two OGTTs.
Read the detailed description
The study is an acute, double-blinded, randomized, cross-over intervention study with sixteen participants with T2D. Initially, a blood sample is obtained (t=-15 min) and at time point 0, the participants will ingest a tablet containing either 12 mg cafestol or placebo. Immediately hereafter an OGTT commences with ingestion of a 75 g glucose solution. In the following 3 hours blood samples are collected at time points 0, 15, 30, 60, 90, 120 and 180 min. The samples will be used for determination of plasma glucose, insulin and cafestol, as well as GLP-1 and GIP. After a one-week washout period, the subject will undergo the same set-up again, however now with the opposite intervention / placebo.

Where is the study taking place?
The record lists 1 site in Denmark. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Area under the curve for glucose (time frame: -15 to 180 minutes from ingestion of intervention/placebo capsule and 75 g. glucose solution). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
