STAR Study Investigating Performance and Safety of the Medical Device SiPore15™

November 4, 2019 updated by: Sigrid Therapeutics AB

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

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.
