**Collagen Solutions plc** (LON:COS), the developer and manufacturer of medical 
grade collagen components for use in regenerative medicine, medical devices and 
in-vitro diagnostics, announced today that the final patient has been assessed in
the eight-year extension clinical study of 15 patients who received a ChondroMimetic
® implant as an osteochondral scaffold for the repair of cartilage defects in the
knee.

**Study Highlights:**

· Clinical trial enrolled 17 patients in 2009-2010; six-month results demonstrated
safety and improved clinical outcomes

· Original six-month MRI data analysed retrospectively in 2017 using quantitative
MRI techniques indicated early improved structural defect repair

· 15 patients enrolled between June and September 2017 for prospective eight-year
extension study

· Full clinical and quantitative MRI data analysis ongoing

The 15 patients were part of the original six-month safety and early clinical outcomes
study of 17 patients in 2009-2010, which showed filling of the original defect and
early signs of integration with healthy cartilage. The current extension phase of
the study with these same patients uses enhanced MRI imaging techniques to permit
longitudinal assessment of durability of cartilage repair and the integration of
the ChondroMimetic implant, as well as clinical outcomes.

A retrospective analysis of the original MRI images was recently performed using
T2 mapping, an imaging technique that is used to quantify the differences between
native and implanted cartilage tissue. The analysis indicated that the ChondroMimetic
scaffold was virtually indistinguishable from surrounding cartilage at six months
following surgery. This technique and other MRI analyses will be replicated for 
the long-term study to assess the [sustainability](https://www.directorstalkinterviews.com/sustainability-green-stocks-news)
and completeness of bone and cartilage defect filling, as well as cartilage quality.

The “Last Patient Out” milestone has now been completed and the data is being compiled
and audited, in line with the Company’s previously announced timelines. Following
the completion of the Clinical Study Report, Collagen Solutions will submit it as
part of a package to the regulatory authorities for approval and the re-establishment
of the CE mark targeting commercialisation outside the US in mid-2018.

The Company has made a presentation available regarding this study update on its

Jamal Rushdy, CEO of Collagen Solutions said: “We are pleased with the progress 
of the long-term ChondroMimetic study and are enthusiastic about the potential for
this product to enable surgeons to treat patients affected by early arthritis and
cartilage defects with a simple, proven, and cost-effective treatment. To our knowledge,
ChondroMimetic will be the only arthroscopically applied cartilage scaffold backed
by long-term evidence, significantly differentiating it from competing therapies.
This study extension is a fundamental step forward in our programme for developing
ChondroMimetic as a product which has the potential to address 450,000 annual cartilage
procedures and provide access to a potential US $500M-$1B market opportunity.”
