Pivotal, Adaptive Phase III Randomized Controlled Trial to Evaluate the Efficacy of a Neocartilage Implant in the Management of ICRS Grade 3 to 4 Articular Cartilage Lesions of the Knee


ISTO Technologies, Inc. is proposing a Phase III clinical study with 225 subjects, to
establish the safety and efficacy of the Neocartilage Implant for the treatment of ICRS
Grade 3 and 4 articular cartilage lesions of the knee compared to microfracture treatment.


In the United States alone, more than 500,000 cartilage lesions per year require some
treatment to reduce pain, restore joint mobility, and prevent further damage caused by the
progression of osteoarthritis. The lack of effective cartilage repair approaches or
products for restoration of defective articular cartilage to its native, hyaline morphology
only continues to exacerbate the incidence of osteoarthritis as these initial defects
enlarge and degrade over a 10 to 20 year period. The repair of cartilage, especially in the
knee, remains a formidable clinical challenge. Regenerative medicine approaches to cartilage
repair have only begun to be explored as possible options and there is a clear trend toward
biological solutions for the repair and regeneration of damaged or diseased articular
cartilage. The study was designed to compare how well the Neocartilage Implant works
against the microfracture therapy, a widely used and accepted cartilage repair therapy. Data
to be collected include Pain and Function in Daily Living scores, symptoms, Function in
Sports and Recreation, and Knee Related Quality of Life. Additionally, MRI and X-rays will
be collected to evaluate the cartilage repair progress. These assessments will be used
through the five years of post-operative follow-up.

Inclusion Criteria:

Generally, the following inclusion criteria must be met, however, this is not a complete
list.

- Male or Female between the ages of 18 and 60

- (1) or (2) articular cartilage lesions of the distal femur ranging in no more than 5
cm2 each

- Ipsilateral knee compartment has intact menisci (or meniscectomized remnant with >
5mm wide rim) and stable ligaments in the affected knee

- 3 months out from initiation of conservative non-surgical management (e.g.hyaluronic
acid injection, activity modification) or previous minimal surgical intervention
(e.g., arthroscopic lavage, debridement) or 12 months out from marrow stimulation for
this condition

Exclusion Criteria:

Generally, if a potential participant meets any of the following criterions, they will not
be eligible for this study. Additionally, more criteria will be evaluated to confirm
eligibility as this list is not a complete list of criteria.

- Osteoarthritis

- Rheumatoid arthritis

- History of septic or reactive arthritis

- Gout or a history of gout or pseudogout in the affected knee

- Osteochondritis dissecans or osteochondral lesions of the knee with bone loss > 6mm
deep

- Bipolar articular cartilage involvement (or kissing lesions) of the ipsilateral
compartment (i.e., > than ICRS Grade 2 on the opposing articular surface)

- Associated damage to the underlying subchondral bone requiring an osteochondral graft

- Is pregnant or breast-feeding

- Has a BMI > 35 (kg/m2)

- Has prior total meniscectomy of either knee

- Has received, within the past three months, intra-articular hyaluronic acid therapy,
or steroid therapy

- Has more than two clinically relevant chondral lesion(s) on the index knee
