Bio-availability of Rectal Artesunate in Children With Severe Falciparum Malaria (REACH)

December 2, 2015 updated by: University of Oxford
The study aims at describing the pharmacokinetic properties of rectal artesunate in well characterized severely ill patients using intravenous artesunate as a comparator.

Study Overview

Status

Status

Indicates the current recruitment status or the expanded access status.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Individually randomized, open label, 2-arm, cross-over, clinical trial. Patients are allocated to receive rectal artesunate at admission and intravenous artesunate after 12 hours or intravenous artesunate at admission and rectal artesunate after 12 hours. All patients are treated for severe malaria with intravenous quinine. Frequent blood samples are taken at fixed intervals after the administration of the first and the second dose of study drug. The time frame is 24 hours and thereafter patients continue the standard antimalarial therapy.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • ADULT
  • OLDER_ADULT
  • CHILD

Accepts Healthy Volunteers

Genders Eligible for Study

All

Description

Inclusion Criteria:

  • Weight ≥6 kilograms and ≤ 34 kilograms
  • Severe malaria (WHO Guidelines 2013; Appendix 1)
  • P. falciparum infection confirmed by Rapid Diagnostic Test (P. falciparum monoinfection or mixed infection with P. ovale or P. malariae)
  • Parents or guardian signed Informed Consent

Exclusion Criteria:

  • Acute diarrhoea defined as > 3 liquid stools in the previous 24 hours
  • Visible anorectal malformations or a disease of the rectum
  • Known hypersensitivity to quinine or artesunate
  • A documented history of an effective dose of parenteral antimalarial in the preceding 24 hours or a single dose of rectal artesunate in the previous 12 hours or a dose of an artemisinin based combination therapy in the previous 6 hours
  • Co-morbidity which in the judgement of the investigator would interfere with the patient treatment or results of the study or place the subject at undue risk
  • Participation in another clinical trial or earlier in the same clinical trial

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
Pharmacokinetics profile of rectal artesunate
Time Frame: 24 hours
The pharmacokinetics profile of rectal artesunate (the study drug), consisting of: area under the concentration-time curve; terminal elimination half-life; elimination clearance; apparent volume of distribution will be measured and compared to the pharmacokinetic profile of intravenous artesunate (the comparator).

These dates track the progress of study record and summary results submissions to ClinicalTrials.gov. Study records and reported results are reviewed by the National Library of Medicine (NLM) to make sure they meet specific quality control standards before being posted on the public website.

Study Major Dates

Study Start

Study Start

The actual date on which the first participant was enrolled in a clinical study. The "anticipated" study start date is the date that the researchers think will be the study start date.

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.

Study Completion (Actual)

Study Completion

The date on which the last participant in a clinical study was examined or received an intervention/treatment to collect final data for the primary outcome measures, secondary outcome measures, and adverse events (that is, the last participant's last visit). The "anticipated" study completion date is the date that the researchers think will be the study completion date.
