About this study
Official title: A Randomized, Double-Blind, Parallel Group, Placebo-Controlled Study to Evaluate the Analgesic Efficacy and Safety of VVZ-149 Injection for Post-operative Pain Following Total Hip Arthroplasty
The purpose of this phase 2 study is to evaluate the efficacy and safety of an analgesic drug candidate, VVZ-149 Injections. The study is designed as randomized, double-blind, parallel, and placebo-controlled study.
Read the detailed description
VVZ-149 is a dual antagonist of GlyT2 and 5HT2A. GlyT2 blockage increases inhibitory synaptic transmission by glycine in the spinal cord, resulting in a reduction of pain transmissions to the brain. 5HT2A blockage decreases descending serotonergic facilitatory modulation on pain transmission by the brain and reduces nociceptor activation in peripheral nerves, which are primary sources of pain in post-surgical pain. VVZ-149 has been shown to have comparable efficacy to morphine in well controlled (blind, complete randomization with a positive control) animal studies using rat models of post-operative pain and formalin-induced pain. The PK/PD study in animals indicates that therapeutic plasma concentration in human subjects will be 600-1,900 ng/ml. A clinical Phase 1 study performed in healthy subjects has shown no clinically significant adverse events up to a plasma concentration level of 3,261 ng/ml other than brief symptoms of mild nausea or dizziness, and mild somnolence when the plasma exposure level is more than 2,000 ng/ml.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing VVZ-149 injections in people with Post-Operative Pain, run by Vivozon, Inc. at 1 site in South Korea.
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 7 inclusion and 19 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.
Where is the study taking place?
The record lists 1 site in South Korea. 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 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?
Change of Pain Intensity (time frame: prior to PCA, at 0,1, 2, 4, 6, 8, 10, 24 hours post-PCA). 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.
