Trial results

Effect of Liraglutide on Microbiome in Obesity

NCT04046822 on ClinicalTrials.gov · last registry update 2019-08-20

70 participants. Its estimated completion date, 9 January 2020, has passed with no update to the record. A lapsed estimate is not a result and not a failure — sponsors are slow to refile — but ClinicalTrials.gov marks it nowhere on the record, so it is noted here. liraglutide is already approved in the US for obesity, so this is asking a further question rather than establishing the drug works at all.
