Study summary

Constipation is a common yet underrecognized supportive care issue in cancer patients. Its consequences extend beyond physical discomfort to include impaired quality of life, reduced opioid adherence leading to inadequate analgesia, and increased risks of fecal impaction, emergency visits, and hospitalization. Current management strategies-including laxatives, stool softeners, prokinetics, and PAMORAs-remain suboptimal due to limited effects on gut dysbiosis, mucosal barrier dysfunction, and chronic inflammation, as well as issues related to polypharmacy, variable efficacy, and long-term tolerability. Hence, there is a clear need for novel, well-tolerated, long-term interventions with nutritional benefits that target the gut microbiota-mucosal barrier-motility axis.

Short-chain fatty acids (SCFAs), particularly butyrate, are key microbial metabolites that may improve constipation through multiple mechanisms: enhancing intestinal motility via enteric nervous system regulation, reinforcing mucosal barrier integrity and mitigating low-grade inflammation, and restoring gut microbial-metabolite homeostasis. Butyrate supplementation therefore holds mechanistic promise for cancer-related constipation.

The "Small Blue Can High Dietary Fiber Butyrate SCFA Yogurt" (Blueglass) is designed with a "probiotics + prebiotics + acids" synergistic fermentation platform, delivering ≥70 mg/100 g butyrate combined with high dietary fiber. Compared with conventional laxatives or single-agent butyrate, this yogurt-based formulation offers potential advantages in patient acceptability, long-term adherence, dual exogenous and endogenous SCFA support, and multi-target action on motility, microbiome, and barrier function, making it a promising candidate for supportive care in this population.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  1. Age ≥ 18 years.
  2. confirmed diagnosis of gastrointestinal .
  3. (ECOG) performance status of 0-2.
  4. Confirmed \< 3 spontaneous bowel movements (CSBM) per week during the 1-week baseline period, accompanied by constipation-related symptoms (e.g., straining, hard/lumpy stools, sensation of incomplete evacuation, etc.).
  5. Anticancer treatment regimen is expected to remain relatively stable during the study period.
  6. Willing and able to provide written and complete electronic diary entries.

Exclusion criteria

Exclusion Criteria:

  1. Mechanical intestinal obstruction, active inflammatory bowel disease, severe rectal stricture, or acute abdomen.
  2. (ANC) \< 1.0 × 10⁹/L or active infection.
  3. New initiation or major dose adjustment of prosecretory or prokinetic agents within the past 2 weeks.
  4. Allergy or to dairy products or any component of the butyrate-containing yogurt formulation.
  5. Deemed unsuitable for enrollment by the investigator (e.g., poor compliance, cognitive impairment, or other conditions that may interfere with study participation).
Terms in these criteria, in plain language(6)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Histologically or cytologically confirmed

The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Your pathology report is the document that shows this.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

ECOG performance status

A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.

0
Fully active, no restrictions.
1
Limited in strenuous activity, but walking and able to do light work, such as housework or office work.
2
Walking and able to look after yourself, but unable to work; up and about more than half of waking hours.
3
Able to look after yourself only in part; in bed or a chair more than half of waking hours.
4
Unable to look after yourself at all; in bed or a chair all day.

Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Absolute neutrophil count (ANC)

The number of neutrophils, white blood cells that help fight infection, in a given amount of blood. Too few raises the risk of infection.

It is a count, not a percentage of the white cells. Limits are written in units that mean the same: ≥ 1.5 × 10⁹/L is ≥ 1,500 per mm³ (µL). Each lab has its own reference range.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.
