About this study

Official title: A Phase 1 Double-Blind, Placebo-Controlled, Randomized Multiple Dose Escalation Study to Evaluate the Safety, Tolerance, and Pharmacokinetics/Pharmacodynamics of a New GMP Formulation of Intravenous Artesunate if Healthy Subjects

The purpose of this study is to establish the safety, tolerability, and pharmacokinetics of a multiple dose of the antimalarial drug artesunate.

Read the detailed description

This study was a Phase 1b, randomized, double-blind, placebo-controlled trial using multiple ascending doses of intravenous artensunate (AS) to determine it's safety, tolerability, and PK in healthy subjects. Subjects were screened within 21 days of dosing. At the screening visit, subject underwent baseline assessments: vital signs were recorded; a physical examination, urinalysis, urine drug screen, and urine pregnancy test were performed; a complete blood cell count (CBC) with differential and indices, reticulocyte count, coagulation markers, and blood chemistry assessments were performed and medical and medication history was collected. Eligible subjects were scheduled for a 6-hour pre-dose electrocardiogram (ECG) and vital sign assessment with measurements taken at approx. the same times as Day 1 (dosing day). On Day 0, subjects were admitted to the clinical pharmacology unit to begin the inpatient phase of the study. Subjects had a brief physical examination and all procedures for the inpatient stay were reviewed. On Day 1, pre-dose vital signs and ECG were performed. Subjects then received study drug or placebo by IV bolus infusion. Subjects were closely monitored by evaluating hemodynamic measurements, periodic ECGs, and assessment of spontaneously reported AEs. Blood was drawn for blood count and chemistry analysis 6h and 24h after each dose. PK blood samples were drawn pre-dose and approx. 5min, 20min, 40min, 1h, 2h, 4h, 6h, and 24h after each dose. On Days 2 and 3 subjects received their second and third doses, respectively, of study drug or placebo with the same monitoring and laboratory measurements as for the first dose. Subjects were discharged 24 hours after the 3rd dose of drug or placebo and were followed as outpatients on Days 7, 10, and 15.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Participants With AEs

    The general strategy of the safety analysis was to examine the clinical tolerability and laboratory safety parameter data and determine if there were any trends amongst the dose levels concerning all AEs and drug related AEs.

    Measured: up to 21 days

  2. Number of Participants With AEs Occurring in Greater Frequency in the 2.0 mg/kg IV AS Group Then in the Placebo Group to Access Safety and Tolerability of AS

    Comparison of number of participants with AEs reported for the placebo control and those treated with the 2.0 mg/kg of IV AS to access safety and tolerability

    Measured: up to 21 days

Secondary outcomes (6)
  1. Cardiovascular Responses: Number of Participants With Changes in Blood Pressure and Heart Rate After Infusion

    Cardiovascular Responses: Number of participants with changes in blood pressure and heart rate after infusion to determine change from baseline

    Measured: screening, on Day -1, on Days 1, 2, and 3, and at each follow-up visit

  2. Range of Pharmacokinetic Parameters for Artesunic Acid After Single 2.0, 4.0 and 8.0 mg/kg Dose of Artesunate Daily for 3 Days (ng*hr/mL)

    For artesunic acid, AUC0-last was determine for each dose; as well as the total area under the curve (AUClastTOTAL), calculated as the sum of AUClast for each of the doses (ng*hr/mL)

    Measured: Pre-dose, 5, 20, 40 minutes after infusion and 1, 2, 4, 8, 24 and 72 hours after infusion

  3. Range of Pharmacokinetic Parameters for Artesunic Acid After Single 2.0, 4.0 and 8.0 mg/kg Dose of Artesunate Daily for 3 Days (ng/mL)

    For the predicted concentration at the time of dose administration (C0) was determine for each dose (ng/mL)

    Measured: Pre-dose, 5, 20, 40 minutes after infusion and 1, 2, 4, 8, 24 and 72 hours after infusion

  4. Range of Pharmacokinetic Parameters for Dihydroartemisinin (DHA) After Single 2.0, 4.0 and 8.0 mg/kg Dose of Artesunate Daily for 3 Days (ng*hr/mL)

    For DHA, AUC24, and AUClast were calculated for each dose, as well as the total area under the curve extrapolated to infinite time (AUC∞TOTAL), calculated as the sum of AUC24 for each dose +C24/λz.

    Measured: Pre-dose, 5, 20, 40 minutes after infution and 1, 2, 4, 8, 24 and 72 hours after infusion

  5. Cmax Assessment After Single 2.0, 4.0 and 8.0 mg/kg Dose of Artesunate Daily for 3 Days (ng/mL)

    Cmax was calculated after single 2.0, 4.0 and 8.0 mg/kg dose of Artesunate daily for 3 days (ng/mL)

    Measured: Pre-dose, 5, 20, 40 minutes after infution and 1, 2, 4, 8, 24 and 72 hours after infusion

  6. Tmax Assessment After Single 2.0, 4.0 and 8.0 mg/kg Dose of Artesunate Daily for 3 Days (hr)

    Tmax was calculated after single 2.0, 4.0 and 8.0 mg/kg dose of Artesunate daily for 3 days (hr)

    Measured: Pre-dose, 5, 20, 40 minutes after infution and 1, 2, 4, 8, 24 and 72 hours after infusion

Questions about this trial

What is this clinical trial studying?

A Phase 1 study testing Intravenous Artesunate in people with Malaria and Malaria, Cerebral, run by U.S. Army Medical Research and Development Command at 1 site in United States.

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 8 inclusion and 17 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 25 Oct 2018. 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 United States. 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. Some participants in this study may receive a placebo. 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 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

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

Are results available for this study?

Yes. Results are posted in the registry (first posted 25 Oct 2018). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

Number of Participants With AEs (time frame: up to 21 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

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 25 Oct 2018.
