Design outcomes

Primary

MeasureTime frame
Phase 1: The primary objective is safety, measured by blood parameters and questionnaires. Phase 2: The primary efficacy parameter of the study is lipid peroxidation, as assessed by urinary concentration of F2-isoprostanes.

Secondary

MeasureTime frame
Phase 2: Secondary endpoints entail the evaluation of effects of daily administration of PD01 on lipid peroxidation (blood measurements), low-grade inflammation (blood and fecal measurements), platelet aggregation (blood measurements), glucose / insulin metabolism (blood measurements), lipid profile (blood measurements), blood pressure & heart rate, body composition, microbiota composition and functioning (fecal measurements), gut barrier function (blood and fecal measurements, urine collection), bioavailability (blood measurements) and tolerance and digestive (dys)comfort.
