Important Step Forward in Osteoarthritis Research: Bioactive Collagen Peptides Stimulate the Regeneration of Cartilage Tissue
collaboration with Kiel University, researchers at the Kiel- based Collagen
Research Institute (CRI) have demonstrated the stimulating effect of special
bioactive collagen peptides (FORTIGEL(R)) in the context of cell experiments.
Last weekend the CRI presented its research findings at the congress of the
Osteoarthritis Research Society International (OARSI) in

high-purity bioactive collagen peptides. “In our investigations we showed
that – alongside the synthesis of Type II collagen – FORTIGEL(R) induces the
increased production of aggrecan, a special proteoglycan which is of central
importance to the cartilage function,” explains Dr.
of the CRI. This provides experimental proof that the application of
bioactive collagen peptides stimulates the renewed synthesis of the
extracellular cartilage matrix.

The CRI has clearly demonstrated at the cellular level that FORTIGEL(R)
brings about an increase in proteoglycan. Previously, the
clinical trial had proved the regenerative effect of FORTIGEL(R) on the
knee-joint cartilage using an objective imaging technique. These two
investigations complement each other.
The double-blinded, placebo-controlled
patients diagnosed with osteoarthritis of the knee and revealed a significant
regeneration of the cartilage tissue in the FORTIGEL(R) group. In the placebo
group cartilage degeneration progressed as before.
To analyze the structural changes in the cartilage tissue the
Following the injection of a special dye into the patient’s knee joint it is
possible to determine the proteoglycan density in the cartilage with a high
degree of accuracy. The results of this clinical trial indicate a significant
increase in proteoglycan after the application of FORTIGEL(R). This delivers
clinical confirmation for the experimental findings of the CRI.
Treatment of osteoarthritis
“The targeted manipulation of the cartilage metabolism opens up new
possibilities for the treatment and prevention of osteoarthritis,” emphasizes
Dr. Oesser. Unlike analgesic and antirheumatic drugs, which merely alleviate
the symptoms and effects, FORTIGEL(R) now offers the potential for an
alimentary, causal therapy.
Worldwide approximately 135 million people suffer from osteoarthritis.
Experts predict a rapid rise in this figure – above all in the industrialized
nations. The prevention of arthritic diseases enjoys top priority, due not
least to the high costs incurred by the healthcare systems.

established in 2003 as an independent research organization. The institute’s
activities centre on degenerative changes to the connective tissue and the
development of complementary and alternative therapies in the area of
osteoarthritis, osteoporosis and wound healing. Since its establishment CRI
has devoted special attention to investigating the effects of collagen
peptides on the extracellular matrix of the articular cartilage.
