About this study
Official title: A Single Ascending Dose Escalation Clinical Trial to Investigate Safety and Pharmacokinetics of VVZ-149 Injection in Healthy Older Male Volunteers
The objective of this study is to investigate the safety, tolerability and pharmacokinetics (PK) of VVZ-149 injection after a single dose or loading/maintenance dose in healthy older male volunteers.
Read the detailed description
VVZ-149 injection, an investigational product (IP) in this clinical study, is a multi-target analgesic drug candidate against glycine transporter type II (GlyT2) and serotonin receptor 2A (5HT2A). The target receptors have been known to play important roles in the induction and transmission of pain signals in the pain-related neural system. There have been efforts to develop new drugs that selectively antagonize the GlyT2 or 5HT2A, but it was unsuccessful due to limitations of single-target drugs. VVZ-149 showed morphine-comparable analgesic and gabapentin-comparable anti-allodynic effects in various rat models of pain.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing VVZ-149 injection in people with Healthy, run by Vivozon, 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 5 inclusion and 20 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 13 Mar 2019. 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?
Dose-limiting toxicity and maximum tolerated dose (time frame: 8 day). 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 13 Mar 2019; AzTrials last refreshed its copy on 8 Nov 2026.
