Study summary

Open labelled, non randomized study to evaluate the effects of Artemisinin based Combined Therapies(ACTs) on schistosomiasis since Praziquantel (PZQ) which is presently the drug of choice for treating Schistosomiasis (STS), is ineffective on immature stages and there is known parasite resistance. ACTs when combined with PZQ, targeting different stages of the life cycle has shown some effectivity.

Read the detailed description

Study population included all subjects in study area who signed a written Informed Consent Form diagnosed with Malaria- STS co-infection. Those excluded were treated with PZQ prior 6 weeks, have drug intolerance or pregnant. At Inclusion, Basic Demographic data was recorded and urine samples analysed. During the follow up visits, urine samples were collected on D28 and D42 (6 weeks post treatment). Post treatment assessment was done on urine samples collected on at least two consecutive days and at the end of follow up, all subjects were treated with a single dose pf PZQ (40 mg/kg) as recommended by WHO.

  • Urinary schistosomiasis diagnosed by presence of Schistosoma haematobium eggs in the urine before malaria treatment
  • Written

Exclusion criteria

Exclusion Criteria:

  • Patients treated with PZQ during the previous 6 weeks
  • Known intolerance /allergy to any study drug
  • Pregnancy
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 Feb 11, 2020, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
