A Prospective, Post-marketing Registry on the Use of ChondroMimetic for the Repair of Osteochondral Defects (OMCM)

This study has been terminated.
(Slow recruitment rate)
Information provided by (Responsible Party):
TiGenix n.v. Identifier:
First received: August 6, 2010
Last updated: September 19, 2011
Last verified: September 2011

The objective of this post-marketing study is to confirm the clinical efficacy and safety outcome of treatment with ChondroMimetic in a patient population within the proposed indication (osteochondral cartilage defects), over a 36 months post-implantation follow-up period.

The primary objective is to collect post-marketing safety data in a real life setting by means of (S)ADR reporting.

The secondary objectives are:

  • Clinical outcome as assessed by patient reported EuroQoL-5D
  • Structural repair as assessed by MRI
  • The number of treatment failures and the time to treatment failure
  • The ease of use of ChondroMimetic as reported by the surgeon

Condition Intervention
Osteochondral Defects Device: Chondromimetic

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: A Prospective, Open Label, Multi-centre, Post-marketing Registry on the Use of ChondroMimetic for the Repair of Osteochondral Defects

Further study details as provided by TiGenix n.v.:

Primary Outcome Measures:
  • Safety data [ Time Frame: on ongoing basis up to 3 years ]
    Safety data as measured by adverse device reactions

Secondary Outcome Measures:
  • EuroQoL-5D [ Time Frame: baseline, 6, 12, 24, 36 months ]
    The EQ-5D is a descriptive system of health-related quality of life states consisting of five dimensions (mobility, self-care, usual activities, pain/discomfort, anxiety/depression) each of which can take one of three responses. The responses record three levels of severity (no problems/some or moderate problems/extreme problems) within a particular EQ-5D dimension

  • MRI [ Time Frame: baseline, 12, 24, 36 months ]
    Structural repair will be assessed by MRI. The available MRIs will be collected and scored by an independent radiologist, using the published MOCART score , and one additional item, level of the subchondral bone plate.

  • Failure rate [ Time Frame: 3 years ]
    Treatment failure is defined as "a re-intervention on the index lesion, prompted by persistence or recurrence of symptoms related to the index knee". The date of failure is the actual date of re-intervention.

Enrollment: 8
Study Start Date: September 2010
Estimated Study Completion Date: April 2016
Estimated Primary Completion Date: September 2015 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Osteochondral lesions
Patients with osteochondral lesions in the knee, the ankle, or other joint
Device: Chondromimetic

The Chondromimetic implant is intended to serve as a scaffold for cellular and tissue ingrowth in osteochrondral defect repair such as bone and/or cartilage.

The plug consists of a chondral layer with collagen and GAG and an osseus layer with collagen, GAG, and calcium phosphate.

Other Names:
  • Osteochondral repair plug
  • CM
