RECRUITING

A Study of Herbal Supplements in Cancer Survivors With Constipation

Study Overview

This clinical trial focuses on testing the efficacy of different digital interventions to promote re-engagement in cancer-related long-term follow-up care for adolescent and young adult (AYA) survivors of childhood cancer.

Description

The purpose of this study is to find out whether MZRW is an effective treatment for constipation in cancer survivors. The researchers will compare MZRW with placebo, a pill that looks like MZRW and is given in the same way, but contains no medication. The researchers will also study the effect MZRW has on the gut microbiome. The gut microbiome is a diverse community of microorganisms living in the digestive system, essential for digestion and immune function.
