About this study
Official title: A Multicenter, Randomized, Controlled, Observer-Blinded, Dose-Response Study to Evaluate the Efficacy in Tracheal Intubation and Safety of Gantacurium Chloride for Injection in Healthy Adult Patients Undergoing Surgery With General Anesthesia
This is a multicenter, randomized, controlled, observer-blinded, dose-response study to evaluate the efficacy in tracheal intubation and safety of gantacurium chloride for injection in healthy adult patients undergoing surgery with general anesthesia.
Gantacurium chloride for injection (previously referred to as AV430A) is a new, investigational non-depolarizing ultra-short acting neuromuscular blocking agent (NMB). Preliminary results in animals and healthy human subjects (Phase 1 studies in adult volunteers) suggest that gantacurium chloride for injection may provide a useful adjunct to general anesthesia by permitting rapid intubation. This Phase 2 study will provide more definitive information on the ultra-short acting profile of the compound by determining the quality of intubation in patients, at 60 seconds, as assessed by a blinded intubator. In addition, the safety of the compound will be assessed. In this study, the efficacy and safety of gantacurium chloride for injection will also be compared to a reference drug, succinylcholine, and to placebo.
The primary objective of this study is to determine the dose-response relationship of gantacurium chloride for injection on tracheal intubation conditions after a single rapid bolus intravenous (i.v.) dose as a component of a propofol/opioid induction-intubation sequence and to assess the safety profile of this compound.

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Gantacurium Chloride for Injection (AV430A) in people with Healthy, run by Avera Pharmaceuticals at 1 site in Germany.
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 9 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 21 Jul 2006. 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 Germany. 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 combined 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.
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 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?
The primary endpoint in this study is the graded intubation scores at 60 seconds after administration of single rapid i.v. bolus doses of study treatments (gantacurium chloride for injection, succinylcholine, or placebo). 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 21 Jul 2006; AzTrials last refreshed its copy on 8 Nov 2026.
