Who may be able to join
- The potential subject must be at least 18 years of age or older.
- The potential subject must agree to attend the weekly study visits required by the protocol.
- The potential subject must be willing and able to participate in the informed consent process.
- The potential subject must have a full-thickness pressure ulcer NPIAP stage 3 or stage 4 without exposed tendon or bone of greater than or equal to one month in duration located on the trunk (sacral, trochanteric, or ischial).
- At enrollment, the potential subject must have a target ulcer with a minimum surface area of 2 cm2 and a maximum surface area of 100 cm2 measured post-debridement with the imaging device.
- The potential subject has adequate off-loading of the ulcer.
Who cannot join

Imaging Device is not required for measurements taken during the historical run-in period (e.g., calculating surface area using length X width is acceptable).
- The surface area measurement of the potential subject's target ulcer decreases by 25% or more during the active 2-week screening phase: the 2 weeks from the initial screening visit (S1) to the TV-1 visit during which time the potential subject received SOC.
- The potential subject is a woman who is pregnant or considering becoming pregnant within the next 6 months.
- The potential subject has end stage renal disease requiring dialysis.
- The potential subject, in the opinion of the investigator, has a medical or psychological condition that may interfere with study assessments.

About this study
Official title: A Multicenter, Prospective, Randomized Controlled Modified Platform Trial Evaluating Several Cellular, Acellular, and Matrixlike Products (CAMPs) and Standard of Care Versus Matched Standard of Care Controls in the Management of Nonhealing Pressure Ulcers
The purpose of this study it to evaluate several cellular, acellular, and matrix-like products (CAMPs) and standard of care versus matched standard of care controls in the management of nonhealing pressure ulcers.
Read the detailed description
To determine the between-arm difference in the proportion of subjects achieving complete closure of nonhealing pressure ulcers with multiple CAMPs plus SOC versus matched SOC controls (mSOC) over 20 weeks using a modified platform trial design. The initial plan is to evaluate two CAMPs; however, the modified platform design permits the inclusion of additional CAMPs.
- Conditions
- Pressure Ulcer, Ulcer, Ulcer, Pressure, Pressure Injury
- Being tested
- ACApatch™, caregraFT™, Standard of Care
- Medical subject headings
- Pressure Ulcer, Ulcer
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ACApatch™Other
Participants will receive weekly applications of ACApatch™ and Standard of Care until ulcer closure, or a maximum of 20 weeks, whichever occurs first.
caregraFT™Other
Participants will receive weekly applications of caregraFT™ and Standard of Care until ulcer closure, or a maximum of 20 weeks, whichever occurs first.
Standard of CareOther
Beginning at the screening visit, participants will receive weekly treatment with standard of care (cleaning, debridement, ulcer moisture balance) until ulcer closure, or a maximum of 20 weeks, whichever occurs first.
| Study group | Role | What they receive |
|---|---|---|
| ACApatch™ + SOC | Experimental | Human amniotic membrane tissue allografts derived from human placental tissue. Receives: Other: ACApatch™ |
| caregraFT™ + SOC | Experimental | Human amniotic membrane tissue allografts derived from human placental tissue. Receives: Other: caregraFT™ |
| Standard of Care | Active comparator | Standard of care will be cleaning, debridement, and ulcer moisture balance. Receives: Other: Standard of Care |
What is being measured
The primary outcome is the main question the study is designed to answer.
Complete closure
To determine the between-arm difference in the proportion of subjects achieving complete closure of nonhealing pressure ulcers with multiple CAMPs plus SOC versus matched SOC controls (mSOC) over 20 weeks using a modified platform trial design.
Measured: 1-20 Weeks
Secondary outcomes (4)
Time to Closure
To determine the between-arm difference in the time to closure over 16 weeks for CAMP plus SOC versus mSOC.
Measured: 1-20 weeks
Percentage Area Reduction
To determine the between-arm difference in the percent area reduction (PAR) at weekly intervals the CAMP plus SOC arms versus mSOC.
Measured: 1-20 weeks
Determine Quality of Life
To determine the between-arm difference in pain for patients that present with a VAS score of greater than 4. Pain will be rated on a scale of 0 to 10, with 0 meaning no pain and 10 meaning the most pain.
Measured: 1-20 weeks
Adverse Events
To evaluate the between-arm difference in the frequency and nature of adverse events in subjects receiving CAMP plus SOC versus mSOC.
Measured: 1-20 weeks

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing ACApatch™ and caregraFT™ in people with Pressure Ulcer and Ulcer, run by Tiger Biosciences, LLC. 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 6 inclusion and 16 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: looking for participants now, as of the sponsor's last update on 23 Sep 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 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
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?
Contact Arshdeep Kaur, MS (1-888-665-5005, arshdeepk@tigerbios.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Complete closure (time frame: 1-20 Weeks). 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 23 Sep 2026.
