Brief Summary:
Tanezumab is effective in reducing the pain associated with chronic pancreatitis.

Condition or disease Intervention/treatment Phase
Chronic Pancreatitis Biological: Tanezumab Other: Placebo Phase 2

Detailed Description:
On 23 Dec 2010 the FDA imposed a clinical halt for anti-NGF compounds due to safety reasons, ie, a case of osteonecrosis which occurred in relation to an anti-NGF compound of another company. All indications with the exception of Cancer Pain are affected resulting in termination of all studies in respective indications. Recruitment of Study A4091044 was stopped effective 27 Dec 2010. Two patients recruited so far did not receive further doses and were followed up for safety until LSLV on 22 Mar 2011.
