Previous research has demonstrated that patients treated with the second-generation antipsychotic olanzapine (OLA) have metabolic dysfunctions and insulin resistance. Researchers from Instituto de Investigaciones Biomedicas “Alberto Sols” and collaborators investigated the impact of intraperitoneal (i.p.) OLA treatment on peripheral insulin sensitivity as well as potential effects of inhibiting the protein tyrosine phosphatase 1B (PTP1B), a negative regulator of insulin signaling.

Incretin therapies based on GLP-1 receptor agonism aid in the loss of weight in obesity, but a relevant part of this loss (25%-40%) is attributed to loss of lean muscle mass, which raises the risk of sarcopenia. Keros Therapeutics Inc. has presented data on RKER-065, a novel modified ActRII-Fc ligand trap that inhibits myostatin and activins and promotes muscle formation.

Recent findings have proposed the combination of two agonist mechanisms – glucagon-like peptide 1 (GLP-1) and fibroblast growth factor 21 (FGF21) – to have a synergistic effect for the treatment of obesity and its associated comorbidities, including metabolic dysfunction-associated steatohepatitis (MASH) and severe hypertriglyceridemia.

Omass Therapeutics Ltd. has identified compounds acting as melanocortin MC2 receptor antagonists reported to be useful for the treatment of congenital adrenal hyperplasia, Cushing syndrome, depression, ectopic ACTH syndrome, polycystic ovary syndrome and septic shock.
