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.
