  12. Questions for open discussions • Based on your opinion, S7A safety pharmacology endpoints in regulatory toxicology studies are generally appropriate for: • CNS safety pharmacology for small molecules ? • CNS safety pharmacology for large molecules ? • As a standalone study?

  13. Questions for open discussions • In your organization, has the ability to add safety pharmacology endpoints onto regulatory toxicology studies had any of the following consequences? • Allowed you to manage safety risk more effectively? • Data contributed to the halting the progression of a compound? • Data addressed a specific concern and supported the continuation of a compound?

  14. Questions for open discussions • Based on your experience, please state any disadvantages of safety pharmacology investigations in toxicology studies? • Based on your experience, please state any advantages of safety pharmacology investigations in toxicology studies?

  15. Questions for open discussions • Have you received regulatory feedback on inclusion of respiratory safety pharmacology in toxicology studies?

  16. Thank you for your time and participation! Looking forward to see you in Phoenix for the 2012 Annual SPS meeting
