Study population

Pediatric participants presenting with diarrhea and testing positive for Cryptosporidium by QuikChek™ and microscopy.

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

  • Age 6 months to 59 months with diarrhea according to the World Health Organization (WHO) criteria (≥3 loose stools daily for at least 2 days)
  • QuikChek™ and Stool microscopy positive for Cryptosporidium at screening
  • Acute (\<7 days), prolonged (lasting 7-13 days), persistent (lasting 14-28 days) or chronic (lasting >28 days) diarrheal illness (≥3 loose stools daily, as defined by WHO) at screening
  • Normal nutritional status, mildly-to-moderately acutely malnourished, or severely acutely malnourished according to WHO definitions (number of participants with severe acute malnutrition will be capped) at screening
  • Parent or primary caregiver is willing to provide and to comply with study procedures, including provision of whole stool samples at the scheduled time points and willing to be followed up to 21 days

Exclusion criteria

Exclusion criteria:

  • Bloody diarrhea, defined as diarrhea with visible blood in stool as observed by the study team member performing the screening or reported by parent/primary caregiver
  • Other morbidity requiring emergency medical care in an intensive care setting at the time of screening
  • Coincident non-enteric infection including upper or lower respiratory infection at screening
  • Any participant whose parent or primary caregiver is unwilling or unable to cooperate with study procedures, in the investigator's opinion
  • If the parent/primary caregiver managing care of the patient has travel plans out of the study area that would preclude clinic or in-home study visits during the expected study follow-up period

Other protocol-defined inclusion/exclusion criteria may apply.

Terms in these criteria, in plain language(1)

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.

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.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 21, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
