About this study
Official title: Dose Finding Study of Pentoxifylline in Children With Cerebral Malaria
The primary objectives of this study is to identify a safe, tolerable dose of pentoxifylline in children with cerebral malaria and to establish an acceptable pentoxifylline dosage regimen for use in multi center Phase II and Phase III studies.
Read the detailed description
This is an open, prospective, dose-escalating study, designed to elucidate the pharmacokinetics, pharmacodynamics, safety, and tolerability of pentoxifylline in children of the ages greater than/equal to 9 months and less than/equal to 96 months with cerebral malaria. The study is designed to evaluate pentoxifylline as adjunct therapy in severe pediatric malaria by evaluating its toxicity and associated adverse events, and by establishing both an acceptable dose and the associated pharmacokinetic profile. The pharmacodynamic effects of four different dose levels (10, 20, 30, and 40 mg/kg/24 hours) will be accessed on the following biological, immunological, and parasitological parameters: cerebral blood flow velocity, tumor necrosis factor concentration, rosetting, coma resolution time, parasite clearance time, and fever clearance time. Due to the variability observed in the biological, immunological, and parasitological parameters under scrutiny, a control group of ten patients will be intercalated in the study (4 patients prior to enrollment of the first pentoxifylline recipient, 2 patients in-between each of the 3 dose escalations). As there is no information about the relationship of treatment duration to biological, immunological, and parasitological effects, treatment will continue for 72 hours, by which time peripheral parasitemia will have cleared in the majority of patients. The selection of the pentoxifylline dosage regimen for the larger, multi center Phase II and Phase III studies will be made on the basis of the maximum tolerated dose (based on clinical and laboratory observations) which minimizes the dose-related side-effects and adverse events (based on pharmacokinetics) while permitting maximum biological, immunological, and/or parasitological effects (pharmacodynamics).

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing Pentoxifylline in people with Plasmodium Falciparum Malaria, run by National Institute of Allergy and Infectious Diseases (NIAID) at 1 site in Kenya.
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 4 inclusion and 4 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: stopped early, as of the sponsor's last update on 27 Aug 2010. 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 Kenya. 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 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
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 was stopped early. 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.
Where can I read the original study information?
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 27 Aug 2010.
