If the March 25 vote from a joint FDA advisory committee meeting is anything to go by, the long and bumpy development road for Pfizer Inc.’s tanezumab, a nonopioid pain drug, may have just gotten longer and bumpier. In what was nearly a unanimous vote, the Arthritis Advisory Committee and Drug Safety and Risk Management Advisory Committee said the sponsor’s proposed risk evaluation and mitigation strategy (REMS) was not adequate to ensure the benefits of tanezumab in alleviating osteoarthritis pain outweigh its risks, which include further joint deterioration.

With the December PDUFA date already blown, Pfizer Inc. is headed into a day-and-a-half FDA advisory committee meeting this week to make the case for 2.5-mg tanezumab, a potential first-in-class treatment in the U.S., partnered with Eli Lilly and Co. Inc., for chronic pain due to moderate to severe osteoarthritis.

Anaptysbio Inc. is calling it quits for developing imsidolimab in treating moderate to severe palmoplantar pustulosis (PPP) after its phase II Poplar trial failed to hit its primary endpoint. However, the company said it would continue imsidolimab development for five other indications, including a phase III trial in treating generalized pustular psoriasis (GPP) that’s set to begin in mid-2021.
