About this study
Official title: A Phase 1 Open-Label, Single-Center Investigator Initiated Trial (IIT) of E-CEL UVEC Cells as an Adjunct Cell Therapy for the Arthroscopic Rotator Cuff Repair in Adults
This is a phase 1b investigator-initiated clinical trial that will evaluate the safety and feasibility of E-CEL UVEC® cells with the aim of improving outcomes for patients with full-thickness rotator cuff tears who undergo arthroscopic surgical repair.
Allogeneic E-CEL UVEC cells will be delivered to the tendon repair site and to the muscle adjacent to the tendon repair site.
Read the detailed description
Full-thickness rotator cuff tears present a clinical challenge, often with occurrence of re-tears after surgical repair and a slow rate of complete functional recovery, which limits daily functional tasks and has negative impacts on qualify-of-life. The frequency of failed healing and re-tear following repair is more pronounced in patients over age 60 due to age-related, intrinsic degenerative changes involving the muscle, tendon, and enthesis.
Healing of the enthesis, the site of tendon attachment to the bone, can be compromised due to microvascular and vascular niche deficiencies resulting from various causes including aging, prior injuries, and/or tissue degeneration.
There is currently no approved adjunct biologic therapy to improve surgical repairs of full rotator cuff tear, enhance post-operative recovery, and decrease the risk of re-tear. This trial will investigate the safety and feasibility of local implantation of E-CEL UVEC cells along with standard-of-care arthroscopic surgical repair of full rotator cuff tears. E-CEL UVEC cells are proprietary allogeneic human umbilical vein endothelial cells produced under cGMP and cGTP regulations.

E-CEL UVECDrug
Local implantation of E-CEL UVEC cells at the supraspinatus tendon repair site
| Study group | Role | What they receive |
|---|---|---|
| E-CEL UVEC | Experimental | Patients will receive an injection of the Cell therapy vehicle into their supraspinatus muscle and tendon at the time of rotator cuff repair.
E-CEL UVEC cells suspended in autologous plasma and combined with thrombin at the implantation site (tendon delivery).
E-CEL UVEC cells suspended in 6.0% Dextran 40 and 10.0% human serum albumin (HSA) (infusion solution) (muscle delivery). Receives: Drug: E-CEL UVEC |
What is being measured
The primary outcome is the main question the study is designed to answer.
Short-term safety
The primary study outcomes are measures of local and systemic safety and toxicity via adverse event (AE) logs (post-operative day 0 to Day 11). AE are evaluated using a 5 point severity scale to grade the AE, 1 (mild) to 5 (death/ fatal).
Measured: 0 surgery to +11 days post op
Secondary outcomes (4)
Long-term safety
The primary study outcomes are measures of local and systemic safety and toxicity via symptom reporting (post-operative day +90 to 1 year post-op). Symptom reporting will evaluate pain and swelling based on a 0 to 100mm visual analog scale range, in addition to further symptom reporting.
Measured: post-operative 90 day to 1 year following the surgical repair
MRI
Re-tear rate based on clinical and MRI evaluation for MRI assessments of muscle and tendon quality, measured as a percentage of total volume (%).
Measured: post-operative 90 day to 1 year
Strength
Shoulder strength during regular intervals post-operatively up to 1 year. BioDex system 3 will measure Peak Toque in Nm, scapular plane abduction strength 0-90 degrees.
Measured: post-operative 90 day to 1 year
PROMS
Patient-reported outcomes post-operatively up to 1 year. ASES affected vs unaffected shoulder score (each test has a maximum score of 100 points).
Measured: post-operative 90 day to 1 year

Questions about this trial
What is this clinical trial studying?
A Phase 1 study testing E-CEL UVEC in people with Rotator Cuff Tears and Muscle Atrophy or Weakness, run by Hospital for Special Surgery, New York 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 5 inclusion and 14 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 20 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?
Short-term safety (time frame: 0 surgery to +11 days post op). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT04057833, which also lists 14 linked publications.
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 20 Aug 2026.
