Outcome Measures

Primary Outcomes (1)

  • Primary objective: safety short (≤3 months) and mid long-term (>3-12 months): : Descriptive analysis

    Assess number of patients with NVD-003 related (S)AEs

    Up to 12 months post-grafting surgery

Secondary Outcomes (5)

  • Long term Safety long-term (>12-24 months): Descriptive analysis

    12-24 months post grafting surgery

  • Tibial length evaluation

    3-, 6-, 12- and 24-months post-GS

  • Bone formation

    3-, 6-, 12- and 24-months post-GS

  • Bone remodeling

    3-, 6-, 12- and 24-months post-GS

  • Bone union

    3-, 6-, 12- and 24-months post-GS

Study Arms (1)

NVD-003 bone graft implant

EXPERIMENTAL

The study includes 2 important surgical procedures, the Adipose Tissue Collection (ATC) and the Grafting Surgery (GS) and 3 stages * Stage 1: A screening, adipose tissue collection \& NVD 003 manufacturing period. * Stage 2: Grafting surgery and 12-month post-GS follow-up period. * Stage 3: long-term safety follow-up period (from post-month 12 to month 24).

Biological: NVD-003, an autologous 3D scaffold free osteogenic graft

Interventions

Bone correction and grafting surgery

Eligibility Criteria

Age2 Years - 8 Years
Sexall
Healthy VolunteersNo
Age GroupsChild (0-17)

You may qualify if:

  • Diagnosed with congenital pseudarthrosis of the tibia (with or without NF1) and presenting with a non-healing Paley type 3 or 4 fracture.
  • Minimum weight of 5kg/11lbs.
  • Maximum 2 previous failed surgical orthopaedic interventions to treat the primary CPT fracture.
  • Acceptable serology and molecular test results excluding the presence of viruses
  • Satisfactory general health condition to undergo surgeries (ATC and GS) with anaesthesia as per local standards.
  • The patient's parent(s) and/or legal guardian(s) provided written informed consent and accepted the participation of the patient in the trial.

You may not qualify if:

  • Bilateral CPT.
  • Presence of CPT without a fracture of the tibia (Paley type 1 and 2).
  • More than 2 failed surgical attempt(s) to treat the primary tibial fracture.
  • Evidence of plexiform neurofibroma of any size or nodular fibroma ≥ 1.2in/3cm on the ipsilateral leg.
  • Clinically significant infection at the target grafting site or systemic infection.
  • Presence of clinically significant hematologic, renal, hepatic, and coagulation laboratory abnormalities (i.e., CBC, PT/INR, Chem-7, and LFTs, etc.).
  • Presence of any auto-immune disease, with exception of well controlled diabetes type 1 or auto-immune thyroid disorders.
  • Any history of experimental therapy with another investigational drug within 60 days prior to screening.
  • Presence of active tumour.
  • Documented metabolic bone disease or any disorder, such as but not limited to osteogenesis imperfecta and osteomalacia, that could interfere with the bone healing and bone metabolism.
  • Chronic, ongoing, or planned use of medications that might affect bone metabolism or bone quality such as bisphosphonates, steroids, methotrexate, anticoagulant therapies, immunosuppressant therapy or immunotherapy.
