FDA lifts partial clinical hold on NEON-2 pembrolizumab trial

Alpine Immune Sciences announced that the FDA has removed the partial clinical hold placed on its NEON-2 trial evaluating davoceticept (first-in-class conditional CD28 costimulator and dual checkpoint inhibitor) in combination with pembrolizumab in adults with advanced malignancies.   The partial clinical hold (now lifted) was implemented in March 2022 after a grade 5 serious adverse event leading to a patient’s death occurred.
