SEN-OA – Targeting senescent cells in osteoarthritis: an innovative therapeutic approach

We propose a multifaceted approach combining innovative biomedical senescence models, ageing animal studies, human sample analyses and screening for senescence-targeting compounds for clinical application to (i) decipher the role of ageing-associated senescence mechanisms in the appearance of OA and (ii) develop innovative treatments for OA patients. If successful, the project could lead to a first- in-man clinical trial.

• WP1. A movie dedicated to the presentation of the SEN-OA project has been made. A round table on the role of patients in research projects has been organized with one of the patient expert and Fondation Arthritis at the 1st French Congress on Regenerative Medicine and Biotherapies in Montpellier (October 2020)
• WP2. Several senescence markers have been validated by immunohistology on different articular samples from murine models and human with OA. A bio-collection of human OA tissues has been implemented.
• WP3. Direct modulation of p16INK4A was shown to partially protect mice from developing OA and a model of senescence in zebrafish was generated to investigate the impact of senolytics. Mesenchymal stromal cells and their derived extracellular vesicles can protect from senescence induction in OA chondrocytes
• WP4. A preliminary screening was performed with a repurposing library to identify Senolytics and Pro-autophagy modulators in human chondrocytes. Validation of several candidates is ongoing.

We have discussed the proposal with a patient group in Paris, they thought the idea novel and worthwhile. We gained their input to the lay summary. We will have two patient representatives to support the writing of our patient information sheets and to help communicate the findings of the project. They will participate to the scientific advisory board. There are no obvious risks of the project to the patients. Technical risk is minimal as the assays involved are already carried out in our laboratories.
