What this trial studies

This clinical study aims to evaluate the efficacy and safety of PiB-specific phages in treating patients with refractory constipation. The research will focus on three main aspects: the distribution of PIB phages in the intestines, their ability to kill PIB bacteria, and the overall therapeutic effects on patients suffering from chronic constipation. Participants will be monitored for their response to the phage treatment, with the goal of generating data to support the development of phage therapies for this condition.

Who should consider this trial

Good fit: Ideal candidates for this study are adults aged 18-70 with confirmed chronic constipation and a positive fecal bacteria test for PIB.

Not a fit: Patients with severe heart failure, hypertension, cerebrovascular diseases, or secondary constipation due to psychotropic drug abuse will not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a novel and effective option for patients suffering from chronic constipation.

How similar studies have performed: While phage therapy is a novel approach, there have been limited studies exploring its efficacy in treating gastrointestinal conditions, making this study a potentially groundbreaking effort.
