Advanced Therapy Medicinal Products - ATMPs -

1. Advanced Therapy Medicinal Products- ATMPs - A case study in health economics: ChondroCelect ATMP - D.Dubois

2. A representative sample of the slides that will be presented and discussed during the course is displayed hereafter.

3. ATMP’s • ATMPs include: • Gene therapy medicinal products • Somatic cell therapy medicinal products • Tissue-engineered products • Centralised procedure registration • Principles of existing legislation on medicines apply: • Marketing authorisation • Demonstration of Quality, Safety and Efficacy • Post-authorisation vigilance ATMP - D.Dubois

4. Unique features in the ATMP regulation • Risk-based approach to determine level of data • Post-authorisation follow-up of safety and efficacy • Incentives and fee reductions ATMP - D.Dubois

5. ChondroCelect First cell-based medicinal product authorized under the European ATMP framework (Regulation 1394/2007) ATMP - D.Dubois

6. ChondroCelect as medicinal product: Autologous cell-based medicinal product (EU/1/09/563/001) Characterised autologous cartilage cells expanded ex vivo expressing specific marker proteins Repair of single symptomatic cartilage defects of the femoral condyle of the knee (ICRS grade III or IV) in adults. Product Active substance Indication Biopsy Implantation Controlled manufacturing Quality control ATMP - D.Dubois

11. Model structure – from model entry to OA onset after 15 years During the 3 years following the knee intervention (microfracture [MFX] or autologous chondrocytes implantation [ACI] using ChondroCelect [CC]), the symptoms can be reduced (‘Success’) or not; in case of continued symptoms, the patient can experience re-operation (‘Re-op’) or not within 5 years; in case of reoperation, the symptoms can be reduced (‘Re-op success’) or not; regardless of symptom reduction, patients will experience OA (‘long-term [LT] problem’) or not, which is evaluated 15 years after the initial intervention in the model.

12. Cost-utility analysis of ChondroCelect (CC) vs microfracture (MFX),base-case and additional scenarios (healthcare payer perspective) ATMP - D.Dubois

13. Acceptability curve of CC vs. MFX, from probabilistic sensitivity analysis The curve shows the proportion of cost-effective strategies depending on the willingness-to-pay level. CC is cost-effective in 80% of Monte-Carlo simulations if the payer has a willingness-to-pay of 22,000 EUR/QALY. ATMP - D.Dubois
