About this study
Official title: Randomized, Double-Blind, Placebo-Controlled, Single-Dose, Dose-Escalation Safety, Pharmacodynamics, and Pharmacokinetics Study of Intravenous Imprime PGG™ Injection in Healthy Adult Subjects
The purpose of this trial is to the assess the safety, pharmacodynamics, and pharmacokinetics of escalating doses of Imprime PGG™ Injection in healthy volunteers.
Read the detailed description
The primary objective of this study is to evaluate the safety and tolerability of a single intravenous dose of Imprime PGG versus placebo when administered to healthy adult subjects by assessing the frequency, type, and severity of treatment emergent adverse events.
The secondary objectives are:
- to determine the pharmacodynamics of a single intravenous dose of Imprime PGG when administered to healthy adult subjects by assessing the number of subjects who experience a 15% or more increase from baseline in the percentage of neutrophils with primed CR3; and
- to derive the pharmacokinetic profile of a single intravenous dose of Imprime PGG when administered to healthy adult subjects by assessing the plasma concentration of Imprime PGG versus time.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Imprime PGG in people with Healthy, run by HiberCell, Inc..
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 6 inclusion and 9 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 11 Oct 2007. Status can change between updates, so confirm with the study contact before making plans.
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?
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?
Evaluate the safety and tolerability of a single intravenous dose of Imprime PGG™ Injection (Imprime PGG) versus placebo when administered to healthy adult subjects by assessing the frequency, type, and severity of adverse events. (time frame: Prospective). 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 11 Oct 2007.
