The clinical hold includes both the suspension of recruitment of new patients and the dosing of existing patients in the osteoarthritis program, as well as patients with osteoarthritis in other studies. The FDA as asked that, later this week, the company present its assessment of the potential implications of the adverse events in the osteoarthritis program for the other tanezumab clinical programs involving non-osteoporosis patients, which include patients with cancer pain, interstitial cystitis, chronic low back pain and painful diabetic peripheral neuropathy. The company is actively working with the FDA, to determine the appropriate course of action, which will serve the best interest of patients.
