First human use of the Nanochon Chondrograft knee implant in Canada

A First in Human (FIH) Early Feasibility Study (EFS) to Evaluate the Safety and Performance of the Nanochon Chondrograft™ Implant for Re-surfacing of Cartilage Lesions

Not applicable Interventional Nanochon, Inc. · NCT07249489

This study will test if the Nanochon Chondrograft implant is a safe surgical option for adults aged 22–60 who have focal knee cartilage lesions.

What this trial studies

This is a first-in-human, single-arm surgical study implanting the Nanochon Chondrograft into focal cartilage lesions of the femoral condyles or trochlea. Eligible adults (22–60 years) must have a recent knee MRI and be able to consent and communicate in English. Participants will undergo the implant procedure at one of two British Columbia centers and be followed postoperatively for safety and clinical outcomes. Key exclusions include systemic bone or cartilage disorders, bilateral knee surgery needs, recent systemic steroids, insulin-dependent diabetes, pregnancy, active litigation or compensation claims, and significant comorbid illness limiting 12‑month survival.

Who should consider this trial

Good fit: Adults aged 22–60 with a single focal cartilage lesion of the medial or lateral femoral condyle or trochlea, able to undergo MRI and surgery, and able to read and speak English are the intended candidates.

Not a fit: Patients with systemic cartilage or bone disorders, those requiring bilateral knee surgery, insulin-dependent diabetes, recent steroid use, pregnancy, active litigation/workers' compensation or severe comorbidities are unlikely to benefit or be eligible.

Why it matters

Potential benefit: If successful, the implant could offer a new surgical option to repair focal knee cartilage defects and potentially reduce pain and improve function.

How similar studies have performed: While other cartilage repair approaches (e.g., matrix-based chondrocyte implants and osteochondral grafts) have shown variable success, this Nanochon Chondrograft represents a novel first-in-human application.

Eligibility criteria

Exclusion Criteria:

* Any known systemic cartilage and/or bone disorder, such as, but not limited to, osteoporosis, chondrodysplasia or osteogenesis imperfecta
* Requires bilateral knee surgery
* Pregnancy, planning to become pregnant or breast feeding
* Any significant illness (metastasis cancer of any type) that decreases the probability of the participant's survival to 12 months
* Known insulin dependent diabetes mellitus
* Steroid treatment (oral or IV) within the past 6 months
* Participant is:

  1. receiving workman's compensation
  2. receiving prescription narcotic medication
  3. active with litigation relating to musculoskeletal injuries or disorders
  4. a prisoner or pending incarceration
* Comorbidities that could impact study participation or results (e.g., autoimmune disorder, HIV, neuropathic pain or fibromyalgia, restless leg syndrome, active infection, or pain requiring chronic pain management), in the opinion of the investigator at the time of enrollment
* Significant psychiatric disorders (e.g., major depression, anxiety disorders, bipolar disorder, and schizophrenia)
* Substance and/or alcohol dependence and/or abuse based on clinical history, physical exam and participant presentation
* Current participation in another drug or device study that, in the opinion of the investigator at the time of enrollment, would interfere with participation in this study
* Participant has claustrophobia or implanted metallic devices (e.g., cardiac pacemakers, insulin pumps, nerve stimulators), medically implanted clips or other electronically, magnetically or mechanically activated implants that would contraindicate undergoing an MRI
* Known allergy or hypersensitivity to any investigational device materials.
