|Condition or disease||Intervention/treatment||Phase|
|PreDiabetes Pre Diabetes Prediabetic State Type2 Diabetes Type2 Diabetes Mellitus Overweight Obese||Device: SiPore15™||Not Applicable|
|Study Type :||Interventional (Clinical Trial)|
|Actual Enrollment :||43 participants|
|Intervention Model:||Single Group Assignment|
|Intervention 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.|
|Masking:||None (Open Label)|
|Official Title:||Open-label, Single-arm, Multicenter Study Investigating Performance and Safety of SiPore15™ in Obese and Overweight Subjects With Prediabetes or Newly Diagnosed Type 2 Diabetes|
|Actual Study Start Date :||January 28, 2019|
|Actual Primary Completion Date :||October 2, 2019|
|Actual Study Completion Date :||October 2, 2019|
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.
SiPore15™ is a taste- and odourless white powder, consisting of precisely engineered micrometre sized synthetic amorphous silicon dioxide. The device is made of pure silicon dioxide, SiO2, which has the CAS Number: 112926-00-8 and EC List number: 601-214-2.
- Performance measured as changes in HbA1c [ Time Frame: From week 1 to week 12 ]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 [ Time Frame: From week 1 to week 14 ]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.
- Performance measured as changes in LDL-C [ Time Frame: From week 1 to week 12 ]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 % [ Time Frame: From week 1 to week 12 ]To measure change in body fat levels (bio electric impedance, BIA) from baseline (week 1) to week 6 and end-of-treatment (week 12).
- Exploratory Endpoint on Medical Device Usability [ Time Frame: From week 1 to week 12 ]
To assess Medical Device Usability by collecting data:
a. Collect information on Ease of use (Easy, neither/nor, difficult) at visit week 2, 6 and end-of -treatment.
- Explorative Endpoint on changes in Cholesterol [ Time Frame: From week 1 to week 12 ]To measure change in total Cholesterol levels from baseline to week 6 and end-of-treatment.
- Explorative Endpoint on changes in microbiome diversity (species not defined) [ Time Frame: From week 1 to week 24 ]To explore changes in microbiome by feces sampling for research at baseline and at week 24.
