By next June or July, Swedish firm Atrogi AB expects to have data from a first-in-human phase Ia/Ib trial of its novel beta-2 adrenergic receptor agonist, ATR-258, which is in development for type 2 diabetes. The study has completed single ascending and multiple ascending-dose arms in 52 healthy volunteers and recently started recruiting 24 patients onto the phase Ib portion.
Fibroblasts expressing the tumor suppressor p16INK4a (a marker of senescence) stimulated lung stem cells from young mice to repair damaged tissue, according to a study from the University of California, San Francisco (UCSF). The finding calls into question therapies that eliminate these senescent cells without considering their beneficial role in tissue homeostasis.
