Eli Lilly and Pfizer announced Oct. 27 that they ceased the development of tanezumab, a pain drug the two companies had been developing for osteoarthritis.

A non-opioid painkiller developed by Pfizer Inc. and Eli Lilly and Co. succeeded in reducing chronic low back pain when used in a stronger dose, results from a late-stage study showed.

Tanezumab, a non-opioid drug developed by Pfizer and Eli Lilly, met the main goals of a late-stage study in which over half of patients reported a significant reduction in hip or knee osteoarthritis pain.

Regeneron and partner Teva said the U.S. health regulator placed a clinical hold on a mid-stage study of their experimental drug for chronic lower back pain.

Drugmaker Regeneron Pharmaceuticals Inc said on Monday its experimental drug to treat moderate-to-severe osteoarthritis pain was successful in a late-stage study.
