Arms of the Study
Arm 1
Arm Type
Experimental
Arm Label
Single-arm
Arm Description
The device will be taken before three daily main meals togteher with water. The dose will be escalated from 1g per main meal to the full dose of 3g per main meal. The device is provided in foil stick-packs packed in boxes with weekly supply. The treatment is for 12 weeks.
Outcomes
Primary Outcome Measures
Performance measured as changes in HbA1c
To measure change in long-term blood glucose levels, HbA1c, from baseline (week 1) to end- -of-treatment (week 12).
Tolerability measured as evaluation of Adverse Events
To assess safety and tolerability by evaluating the frequency and incidence of both adverse events (AEs) and device related adverse events (ADEs) during the study treatment and follow-up, from baseline (week 1) until week 14.
Secondary Outcome Measures
Performance measured as changes in LDL-C
To measure change in LDL-C blood levels from baseline (week 1) to week 6 and end-of- treatment (week 12).
Performance measured as changes in body fat %
To measure change in body fat levels (bio electric impedance, BIA) from baseline (week 1) to week 6 and end-of-treatment (week 12).

5. Study Description
Brief Summary
The primary objective of STAR01 is to evaluate the performance and safety of the medical device (class IIb) SiPore15™ after a 12-week long treatment in the target population of obese and overweight subjects with prediabetes or newly diagnosed type 2 diabetes. The expected performance and safety of the device is based on the safety and efficacy results seen in an earlier First-in-Man (FIM) study. The safety and tolerability of SiPore15™ is based on the well-established and extensive use of food grade silicon dioxide and favorable data from the FIM study. Data on side-effects will be collected for verification of device safety. The study duration is 24 weeks in total, 12 weeks from baseline on investigational medicinal device (IMD) treatment, with additional 12 weeks off treatment. The study population is planned for forty (40) subjects to be enrolled, male and females, age >18 years and fulfilling all inclusion criteria but none of the exclusion criteria.

Interventional Study Model
Single Group Assignment
Model Description
The single-arm study is designed to collect data on changes over time, i.e. comparing the pre-treatment/baseline value with the value achieved after full treatment (12 weeks). Thus, each individual act as his/her own control. The study design has been discussed with notified bodies, and deemed appropriate as there is no state-of-the-art pharmacotherapy for treatment of prediabetes to compare with.
