Frequently Asked Questions

These questions and answers are submitted by anonymous patients, and have not been verified by our internal team.

What aims does this clinical trial strive to accomplish?

"This trial's primary evaluation metric over the blood analysis timeline of baseline to 72 hours will be changes in serum retinol concentrations. Secondary measurements include alpha-amylase and alpha-glucosidase inhibition activities, measured using ELISA enzyme activity assays and expressed as IC50 values; additionally, alterations in serum insulin concentration from day 8 to 11 of each arm shall also be monitored."
