Large Finnish and Swedish registry cohorts show clozapine is associated with lower psychiatric hospitalisation across schizophrenia-spectrum, bipolar disorder and severe depression without increased overall mortality or hospitalisation.
Three multinational phase 3 trials found no clinically meaningful cognitive benefit of the GlyT1 inhibitor iclepertin versus placebo in schizophrenia, though the drug was well tolerated. Results highlight methodological and biological chall
A living systematic review of 30 RCTs (n=1,480) finds moderate-to-large symptom reductions for MDMA in PTSD and serotonergic psychedelics in major depression and anxiety, but high risk of bias and low certainty overall; pragmatic, longer, a

In ENLIGHTEN, a biomarker-guided randomized trial, ANK3-positive patients with treatment‑resistant depression randomized to liafensine achieved larger MADRS improvements than placebo (mean difference −4.4; 95% CI −7.6 to −1.3; P = .006), wi
