What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Regenn® Negative Pressure Therapy SystemDevice
Also called NPWT, Negative Pressure Wound Therapy
Controlled application of negative pressure (i.e., reduced atmospheric pressure or mild vacuum) to manage the wound environment.
Prevena™ Incision Management SystemDevice
Also called NPWT, Negative Pressure Wound Therapy
Controlled application of negative pressure (i.e., reduced atmospheric pressure or mild vacuum) to manage the wound environment.
| Study group | Role | What they receive |
|---|---|---|
| Treatment Arm | Experimental | This group will receive the study device, Regenn® Negative Pressure Therapy System, a form of Negative Pressure Wound Therapy (NPWT). Regenn® Therapy manages the surgical wound by the application of reduced pressure therapy (i.e., mild vacuum). Reduced pressure therapy is controlled by a hand-sized, battery-operated pump and is delivered by an attached small, dressing that the surgeon places in the surgical wound at the end of the surgery. Reduced pressure therapy is applied while the patient recovers from surgery. Receives: Device: Regenn® Negative Pressure Therapy System |
| Control Arm | Active comparator | This group will receive the control device, also a form of Negative Pressure Wound Therapy (NPWT), which manages the surgical wound by the application of reduced pressure therapy (i.e., mild vacuum). Reduced pressure therapy is controlled by a hand-sized, battery-operated pump and is delivered by a small tube connected to a wound dressing placed over the closed surgical wound at the end of the surgery. Reduced pressure therapy is applied while the patient recovers from surgery. Receives: Device: Prevena™ Incision Management System |
What is being measured
The primary outcome is the main question the study is designed to answer.
Device-related Serious Adverse Event Rate
The device-related serious adverse event rate associated with the use of the investigational device and the comparator device. Wound complications requiring surgical intervention, such as wound dehiscence, will be the primary indicator of blood supply at the wound site, damage to the surrounding tissue, and progression of wound healing.
Measured: Post-operative follow ups at 2-8 weeks and 3-6 months.
Secondary outcomes (2)
Post-operative Pain Profile
Post-operative pain will be assessed using the Numerical Rating Scale (NRS), a validated pain measurement scoring system with a pain rating scale of 0 - 10, where zero means "No pain" and 10 means "The worst pain imaginable"
Measured: Post-operative up to the 3-6 month follow up visit.
Adverse Events Related to the Investigational Device
The number and type of adverse events associated with the use of the investigational device. Assessment will include wound complications not requiring surgical intervention, device complications, medical complications and infections complications.
Measured: Post-operative follow ups at approximately one month and three months.

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing Regenn® Negative Pressure Therapy System and Prevena™ Incision Management System in people with Surgical Wound, run by Progenerative Medical, Inc 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 34 inclusion and 0 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: under way, not looking for participants, as of the sponsor's last update on 27 Aug 2026. 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. 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?
This study is still under way. Results are not available in the source record yet.
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?
Device-related Serious Adverse Event Rate (time frame: Post-operative follow ups at 2-8 weeks and 3-6 months.). 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 27 Aug 2026.
