Clinical Trial With MBK-01, Intestinal Microbiota Capsules, for the Treatment of Patients With Recurrent Diverticulitis
Recruiting now · Phase 2
Conditions studied: Diverticulitis, Diverticulitis of Sigmoid
In brief
Patients with diverticulitis experience a prolonged course of the disease and report a variety of physical, psychological and social symptoms, which highly impacts in their quality of life. Although antibiotic therapy has been the preferred treatment option for acute diverticulitis, it does not control the disease in 40 percent of the patients with complicated diverticulitis and 13 to 23 percent of the patients with non-complicated diverticulitis, which results in chronic and recurrent episodes of diverticulitis. As the episodes repeat, the outpatient conservative treatment has worse success rates and the incidence of complicated diverticulitis with abscess increases up to five times. Therefore, it is of great importance to establish new treatments in order to avoid the recurrences of the disease. As of today, there is not enough evidence of the efficacy of current treatment options to prevent recurrences in patients with diverticulitis, but recent approaches suggest the modification of intestinal microbiota as a preventive strategy. Microbial imbalance (dysbiosis) has been proposed as a mechanism involved in the transition from diverticulosis to diverticulitis, inflammation and some of the symptoms of the disease. In this way, fecal microbiota transplantation (FMT) could have an important role in the prevention of new episodes, as it can modify the composition of the intestinal microbiota in a less invasive and more physiological way. Until now the efficacy of FMT in patients with recurrent diverticulitis has not been assessed; however, its benefits and safety have been demonstrated in studies for inflammatory bowel disease (IBD), a pathology with similarities to diverticulitis in its symptoms and underlying inflammation. The objective of the present clinical trial is to assess the efficacy of MBK-01 (heterologous lyophilized intestinal microbiota oral capsules) in reducing the frequency of episodes in recurrent diverticulitis, its safety and tolerability and to determine the optimal dosing regimen.

Who can join
Age: 18 and older, up to 70. Sex: any. Healthy volunteers: not accepted.
You may qualify if…
- Patients of both sexes aged 18-70 (both included).

- Not having had any symptomatic episode of acute diverticulitis in the 30 days prior to signing the informed consent.
- In the case of women and men of reproductive age, for safety, those who agree to follow the required contraceptive measure from the signing of the informed consent until the penultimate visit of the follow-up period.
- Patients who have signed the informed consent, either autonomously or through a legal representative.
You may not qualify if…
- Patients for who the information on episodes of acute diverticulitis required for inclusion in the study cannot be fully verified.
- Patients with acute diverticulitis in the ascending colon, transverse colon or other locations other than the descending or sigmoid colon.
- Previous colonic resection of any segment of the colon.
- Medical history of colorectal cancer.
- Having taken a mechanical colonic preparation in the 3 months prior to signing the informed consent.
- History of abdominal surgery.
- Allergy or intolerance to any component of the investigational medicinal product or ancillary medicinal products (amoxicillin, clavulanic acid, fosfomycin or metronidazole) used in the trial.
- Prior administration of fecal microbiota transplantation (FMT).
- Systemic antibiotic treatment in the 30 days prior to signing the informed consent.
- Taking a marketed probiotic/prebiotic/symbiotic in the 30 days prior to signing the informed consent.
- Treatment with rifaximin or mesalazine in the 30 days prior to signing the informed consent.
- Presence of hereditary or acquired immunodeficiency.
- Chronic infectious diseases such as hepatitis B virus (HBV), hepatitis C virus (HCV) or human immunodeficiency virus (HIV).
- Pregnancy or lactation.
- Any other condition that, in the opinion of the investigator, could prevent or hinder compliance with the study.
