Repair and Regeneration of Articular Cartilage, and the Repair and Regeneration of Fibrocartilaginous Tissues

Brief Description

The invention provides methods for the protection, repair and regeneration of articular cartilage, and fibrocartilaginous tissues using recombinant parathyroid hormones, such the FDA approved biologic agent – teriparatide (Forteo®, Eli Lilly).

 

Problem Solved by this Technology

Currently, the only treatments for cartilage degeneration and osteoarthritis (OA) involve palliation focused on pain management and joint replacement. The longstanding inability to develop a disease-modifying therapy that can rejuvenate joint cartilage is a great unmet need considering the high prevalence of OA nationally (>25% of the US population by 2020) and globally.

 

Applications

The current invention represents the first and only disease modifying treatment to date that protects against cartilage degradation and regenerates cartilage that has been lost as a result of joint injury or OA. Using a mouse model of posttramatic OA, the inventors have demonstrated that one month of daily injections of Forteo® prevents progressive articular cartilage loss while inducing chondroregeneration. Specifically, Forteo® stimulates articular cartilage thickening via an induction of cartilage matrix production by cartilage cells. Clinical trials of Forteo® as a cartilage-regenerating therapy in humans have been planned.
