Trial summary

Cerebral malaria is the most lethal complication of P.falciparum infection with a mortality rate between 5 and 40%. Intravenous quinine remains the recommended treatment for cerebral malaria. However its administration is often not feasible due to lack of simple equipment or trained staff. Read more about this study

About this study

Official title: Efficacy of Intrarectal Versus Intravenous Quinine for the Treatment of Childhood Cerebral Malaria: a Randomized Clinical Trial

Cerebral malaria is the most lethal complication of P.falciparum infection with a mortality rate between 5 and 40%. Intravenous quinine remains the recommended treatment for cerebral malaria. However its administration is often not feasible due to lack of simple equipment or trained staff. When referral is not possible, a viable alternative is needed. The intrarectal route is of interest in children since it is painless and simple. Studies of the efficacy of intrarectal quinine in the treatment of cerebral malaria are limited. The study aims to establish the efficacy of intrarectal quinine in the treatment of childhood cerebral malaria.

Cerebral malaria is the most lethal complication of P.falciparum infection with a mortality rate between 5 and 40%. Intravenous quinine remains the recommended treatment for cerebral malaria. However its administration is often not feasible due to lack of simple equipment or trained staff. When referral is not possible, a viable alternative is needed. The intrarectal route is of interest in children since it is painless and simple. A few studies in Francophone Africa have reported clinical efficacy and tolerance of intrarectal quinine. Although the studies were randomized trials, they were not blinded and did not use the WHO definition of cerebral malaria as selection criteria.

The current study aims to establish whether intrarectal quinine is as effective and as safe as intravenous quinine in the treatment of childhood cerebral malaria.

To address the shortcomings of the Francophone African studies, the investigators have designed a randomized, double blind placebo controlled clinical trial to include patients who meet the WHO definition of cerebral malaria.

Hypothesis:

Intrarectal quinine (15mg/kg every 8 hours) given to children with cerebral malaria, will lead to a shorter parasite clearance time (39.9 hours) than intravenous quinine (55.0 hours).

The investigators calculated a sample size of 54 patients in each group for 90% power and 95% confidence. In the calculation, the researchers assumed that the children receiving intrarectal quinine would have a mean parasite clearance time of 39.9 (SD 24.3) hours and those receiving intravenous quinine would have a mean parasite clearance time of 55.0(SD 24.3) hours (27.5% effect size), according to a study by Aceng, Byarugaba and Tumwine in the same hospital.

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing Intrarectal quinine in people with Cerebral Malaria, run by Makerere University at 1 site in Uganda.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 4 Aug 2005. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Uganda. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Parasite clearance time. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT00124267, which also lists 6 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 4 Aug 2005.
