Phase II/III Randomized Trial of UC-MSC Secretome vs Sodium Hyaluronate in Knee Osteoarthritis (SECRET-OA)

May 7, 2026 updated by: Universitas Sriwijaya

A Phase II/III Randomized Double-Blind Multicenter Study Comparing UC-MSC-Derived Secretome and Sodium Hyaluronate on Pain and Function in Patients With Kellgren-Lawrence Grade 2-3 Knee Osteoarthritis

This study is a randomized, double-blind, multicenter Phase II/III clinical trial designed to evaluate the effectiveness and safety of umbilical cord-derived mesenchymal stem cell (UC-MSC) secretome compared with sodium hyaluronate in patients with knee osteoarthritis. Knee osteoarthritis is a common degenerative joint disease that causes chronic pain and functional limitation. Participants will be randomly assigned to receive intra-articular injections of either UC-MSC-derived secretome or sodium hyaluronate. The study aims to assess improvements in knee pain, physical function, and overall clinical outcomes, as well as to evaluate the safety of the interventions over the study period.

Detailed Description

This multicenter, randomized, double-blind Phase II/III clinical study aims to compare the efficacy and safety of intra-articular UC-MSC-derived secretome with sodium hyaluronate in patients with Kellgren-Lawrence grade 2-3 knee osteoarthritis. Eligible participants will be randomly allocated to one of two treatment arms. Clinical outcomes will be evaluated using validated pain and functional assessment tools at predefined time points. Safety assessments will include monitoring of adverse events throughout the study period. The results of this study are expected to provide evidence regarding the potential role of UC-MSC-derived secretome as an alternative therapeutic option for knee osteoarthritis.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Description

Inclusion Criteria:

  1. Diagnosed with primary OA in one or both knees based on American College of Rheumatology (Clinical and Rheumatology criteria). If both knees have OA, the knee with the OA grade that falls within the inclusion criteria (grade 2-3) will be selected. If both knees meet the inclusion criteria, the knee with the highest grade and the one that is most uncomfortable will be chosen.
  2. Males or females in the age range 40-70 years
  3. Symptomatic knee OA (defined by pain at the affected joint for at least 3 months before inclusion and visual analog scale 40 - 70 mm on a 100 mm Visual Analog Scale (VAS).

  7. Ability to provide written informed consent and willing to participate the study

Exclusion Criteria:

  1. Participants who, based on physical examination and clinical history (anamnesis), are in the active or acute phase of cardiac, pulmonary, hematological, hepatic, renal, systemic autoimmune, immunodeficiency, or coagulation disorders that may interfere with the administration of the study drug (Secretome or Sodium Hyaluronate) will be excluded,
  2. Diagnosed with a meniscal rupture based on clinical history (anamnesis) and physical examination. If the anamnesis and physical examination show symptoms and signs of a meniscal rupture, further evaluation will be performed using ultrasound (USG),

  4. Participants with other pathological lesions on knee X-rays from the screening examination will also be excluded,
  5. History of any form of secondary arthritis in the knee due to trauma,
  6. History of surgery or major trauma to the knee joint
  7. Has knee effusion,
  8. Has any other inflammatory disorder of the knee joint
  9. Diagnosed with active malignancy.
  10. History of stem cell or secretome therapy.
  11. Intra-articular injection of corticosteroid and/or prior treatment with Sodium Hyaluronate and/or platelet rich plasma (PRP) in past 3 months.
  12. Use of NSAIDs and/or chondroprotective supplements, such as glucosamine and chondroitin sulfate, within 7 days before the trial, whether used orally, topically, or via injection,
  13. Undergoing immunosuppressive therapy, or anticoagulant therapy, or corticosteroid therapy.
  14. For women of child-bearing potential: positive pregnancy test or lactating (females who were planning pregnancy within the next year were excluded).
