Effects of a novel histamine 3 receptor (H3R) on positive emotion and reward processing: methods and preliminary data in an ongoing phase 2 proof-of-concept study (ECNP 2024) - "In a phase 1 trial, ALTO-203 acutely increased positive subjective emotion measured by the Bond-Lader Visual Analogue Scale (BL-VAS) at a level comparable to modafinil, a drug known to enhance reward system dopamine release. Results from preclinical and early human studies show promising pharmacodynamic effects of ALTO-203 on reward system dopaminergic functioning and analogous subjective responses in humans. Based on these promising translational findings, ALTO-203 is presently in a Phase 2 POC study to determine its clinical and biological effects in patients with MDD and anhedonia."
