Detailed Description
Adult patients with haemorrhoids meeting all the eligibility criteria will be allocated in three study arms: test, placebo and benchmark.
Approximately twenty-two subjects per group will be enrolled to assure that approximately 20 subjects in each group complete the study.
The study will be conducted in Armenia.The study will last approximately 2 weeks for each subject and will consist of 3 visits.
The first subject first visit is planned for June 2021, and the study will continue until the target sample size is reached.
