Trial summary

Malaria is fatal and increases the risk of death among children with sickle cell anemia. Chemoprophylaxis significantly improves quality of life in these children. In Uganda Chloroquine is the drug of choice for prophylaxis and yet it's effectiveness is limited due to high levels of resistance throughout the country. Read more about this study

About this study

Official title: Presumptive Treatment With Sulfadoxine- Pyrimethamine Versus Weekly Chloroquine for Malaria Prophylaxis in Children With Sickle Cell Anemia

Malaria is fatal and increases the risk of death among children with sickle cell anemia. Chemoprophylaxis significantly improves quality of life in these children. In Uganda Chloroquine is the drug of choice for prophylaxis and yet it's effectiveness is limited due to high levels of resistance throughout the country. Intermittent presumptive treatment with sulfadoxine - Pyrimethamine a new approach to malaria prevention, has shown great potential in reducing incidence of malaria and anaemia among high risk groups such as pregnant women and infants. However no studies have been done in Uganda to determine if presumptive treatment with sulfadoxine- pyrimethamine reduces the incidence of malaria in children with sickle cell anaemia.

Hypothesis : Presumptive treatment with sulfadoxine- Pyrimethamine is better than weekly chloroquine in reducing incidence of malaria in children with sickle cell anaemia.

Malaria is fatal and increases the risk of death among children with sickle cell anemia. Chemoprophylaxis significantly improves quality of life in these children. In Uganda Chloroquine is the drug of choice for prophylaxis and yet it's effectiveness is limited due to high levels of resistance throughout the country. Intermittent presumptive treatment with sulfadoxine - pyrimethamine a new approach to malaria prevention, has shown great potential in reducing incidence of malaria and anemia among high risk groups such as pregnant women and infants. However no studies have been done in Uganda to determine if presumptive treatment with sulfadoxine- pyrimethamine reduces incidence of malaria among high risk group such as children with sickle cell anaemia.

We calculated a sample size of 110 patients in each group for a power of 95% assuming that the incidence of malaria in children receiving weekly chloroquine will be 0.36 and those receiving presumptive treatment with sulfadoxine - pyrimethamine the incidence would be 0.16 according to (schellenberg et al )

Questions about this trial

What is this clinical trial studying?

A Phase 3 study testing sulfadoxine pyrimethamine in people with Sickle Cell Anemia and 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 1 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: finished, as of the sponsor's last update on 2 Jul 2009. 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?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

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?

Malaria episodes (time frame: 4 weeks). 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 NCT00399074, which also lists 3 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 2 Jul 2009.
