Lyophilized and Micronized Particulate Human Amniotic and Umbilical Cord (TTAX03) for KL Grade 3-4 Knee OA
April 8, 2024 updated by: Tissue Tech Inc.
A Phase 2, 52-Week Trial of TTAX03 vs. Saline as a Single Intra-articular Injection in Kellgren-Lawrence Grade 3-4 Knee OA
It is hypothesized that a single Intra-articular Injection of TTAX03, 100mg in 2mL of saline, will have more benefit with respect to the proportion of responders 12 weeks post-injection than an equal volume of saline, based on the OMERACT-OARSI responder criteria.

Detailed Description
This trial is designed as a Phase 2 randomized, placebo controlled, double-blinded parallel design to be conducted at multiple sites throughout North America.
One dose level of TTAX03 (100 mg) will be tested against an equal volume of saline, which is the suspension vehicle (i.e., excipient).
Each subject will receive a single IA injection into the knee under local anesthesia, with two safety follow-up visits in the first eight days and a third at the end of two weeks post injection.
Subsequent visits will occur at the end of 6 and 12 weeks for evaluation of response, with the end of 12 weeks being the primary endpoint.
Additional visits will occur at 6, 9 and 12 months (end of weeks 26, 39, 52) to evaluate duration of benefit and overall impression of change from baseline, as well as safety.
The primary endpoint will be assessed at 12 weeks post receiving the assigned Intra-articular injection.

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
Ages Eligible for Study
35 years to 85 years (Adult, Older Adult)
Accepts Healthy Volunteers
No
Description
Inclusion Criteria:
- Able and willing to provide written informed consent
- ≥ 35 and ≤ 85 years of age (until a cap of 30 subjects < 50 years of age is reached, at which point this will convert to ≥ 50 and ≤ 85 years of age)
- Able to reliably complete the KOOS self-administered questionnaire
- Clinical diagnosis of OA of the index knee, with pain onset more than one year prior to screening according to subject recall
- KL grade 3 or 4 in the index knee
- Pain score (KOOS) over the past week ≥ 70 in the index knee at Screening (the index knee will be the more painful knee by ≥ 20 in the case of bilateral disease)
- A ≥ 3 months history of insufficient pain relief from IA hyaluronic acid or a ≥ 3 months history of insufficient pain relief from IA corticosteroids, unless they are medically contraindicated for the subject
- A ≥ 3 months history of insufficient pain relief from other currently recommended treatments, including weight loss and physical therapy
Any two of the following:
- Severe knee pain or stiffness that limits everyday activities, including walking, climbing stairs, and getting in and out of chairs. Finding it hard to walk more than a few blocks without significant pain and need to use a cane or walker
- Moderate or severe knee pain while resting, either day or night
- Chronic knee inflammation and swelling that does not improve with rest or medications
- BMI ≤ 40 kg/m2
- Adequate bone marrow function (ANC > 1000 × 109 /L, platelets ≥ 100,000 × 109 /L, Hgb ≥ 10 g/dL)
- Adequate hepatic function (AST/ALT ≤ 1.5 × ULN, total bilirubin ≤ 1.2 × ULN)
- Adequate renal function (creatinine ≤ 1.2 × ULN)
- Negative urine test for opioids (including synthetic opioids)
- If female and of child-bearing potential, willingness to use effective birth control during the study.
Exclusion Criteria:
- Cognitive impairment, mental illness, neuroses or untreated depression that would preclude understanding or reliably completing the patient reported outcome measures
- Non-ambulatory, bedridden, or with active fibromyalgia, radiculopathy, painful peripheral neuropathy, vascular insufficiency, hip OA or other joint disease severe enough to prevent assessment of knee pain or causing functional impairment
- Current use of opioid analgesics, or positive urine laboratory test for opiates during the screening period
- Hyaluronic acid, corticosteroid, platelet rich plasma or stem cells IA knee injections within the prior 3 months, oral or intramuscular corticosteroids within the prior 2 months
- Scheduled knee arthroscopy or knee surgery in either knee within 12 weeks from enrollment
- Known or suspected joint infection of either knee
- History of knee ligament surgery in the past 12 months
- Acute injury to the knee in the past 3 months resulting in difficulty walking for more than 24 hours
- History of inflammatory joint diseases, crystalline diseases such as gout or pseudogout, systemic lupus, rheumatoid arthritis, autoimmune disease or Crohn's disease
- Previous repair of a cruciate ligament, osteochondral autograft transfer, mosaicplasty, subchondral surgery (subchondroplasty) or previously diagnosed subchondral insufficiency fracture
- Comorbid conditions that include the following: known other causes of arthritis (infectious arthritis, or psoriatic arthritis), osteomyelitis, cardiopulmonary disease that limits walking more than knee pain, bone metastases or Paget's disease involving the lower extremities.
- Psoriasis or other acute or chronic inflammatory conditions or infection affecting the skin over the index knee
- Symptoms of locking, intermittent block to range of motion or loose body sensation which could indicate meniscal displacement or an intraarticular loose body in the index knee

- History of substance abuse in the past 2 years

- Severe concurrent illness which, in the view of the investigator, would interfere with this 52 week study
- Any condition which, in the opinion of the investigator, would make a patient a poor candidate for this study
- Positive blood pregnancy test or known pregnancy
