Mytocel MSK With AMTEarly Phase 1NCT07453953
A Comparison of Clinical Efficacy of Mytocel MSK With AMT and PRP Injections in Patients With Knee Osteoarthritis
A Early Phase 1 study testing PRP in people with Mytocel MSK With AMT, run by Taichung Veterans General Hospital.
Trial summary
Osteoarthritis is the most common joint disease, frequently affecting the knee joint. As the cartilage within the joint wears down, the balance between degeneration and regeneration is gradually disrupted, causing pain during joint movement. Read more about this study

About this study
Osteoarthritis is the most common joint disease, frequently affecting the knee joint. As the cartilage within the joint wears down, the balance between degeneration and regeneration is gradually disrupted, causing pain during joint movement.
Mytocel MSK with AMT (Autologous Micrograft Technology) is an autologous micrograft technology, the first biocompatible solution that can be directly implanted into the joint using the patient's own tissue. It possesses regenerative repair and pain-relieving effects, rapidly improving joint health and alleviating pain and stiffness. It is primarily applied to the musculoskeletal system; this therapy has been proven to have tissue regeneration potential and effectiveness in multiple medical fields. This project will harvest ear cartilage tissue, mechanically separate and precisely filter it to create a Mytocel MSK with AMT cell suspension rich in cartilage precursor cells and mesenchymal stem cell markers (CD44, CD90, CD117), which will then be injected into the knee joint cavity. It is expected to help patients repair cartilage, reduce pain, and improve their quality of life.
PRP is a common treatment for knee osteoarthritis, but its effects are short-lived and require multiple injections. Mytocel MSK with AMT may achieve longer-term and more stable clinical improvement with a single application. This project will use questionnaires and MRI examinations to observe changes in pain, functional recovery, and the degree of cartilage repair before and after treatment. The data will be used to analyze and compare the differences between Mytocel MSK with AMT and PRP treatment.

What is being measured
The primary outcome is the main question the study is designed to answer.
Change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score at 52 weeks
The Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) is a validated questionnaire assessing pain, stiffness, and physical function in patients with knee osteoarthritis. The total score ranges from 0 to 96, with higher scores indicating worse symptoms. The outcome measure will be the change in total WOMAC score from baseline to 52 weeks.
Measured: 52 weeks

Questions about this trial
What is this clinical trial studying?
A Early Phase 1 study testing PRP in people with Mytocel MSK With AMT, run by Taichung Veterans General Hospital.
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 3 inclusion and 11 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: opening soon, as of the sponsor's last update on 5 Oct 2026. 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. 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?
Early Phase 1 (sometimes called Phase 0) studies give a very small amount of a treatment to a few people, mainly to see how the body handles it.
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 Chung Yuh Tzeng (886-9921375166, tcy0545@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Change from baseline in Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) total score at 52 weeks (time frame: 52 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 5 Oct 2026.
