NRBO - They are going the "Hormone" route as oxyntomodulin is one of the many well known hormones involved in appetite. It is an interesting hormone to go after as one of the properties this hormone exhibits is that it "inhibits gastric acid secretion".
Hunger Hormone Primary location of production Receptors Action Satiety Oxyntomodulin Distal ileum and colon GLP-1 receptor Inhibiting gastric acid secretion, decreasing gastric emptying, and decreasing pancreatic enzyme secretion
Commons sense would tell you this would theoretically increase tolerability. It certainly is worth investigating and I would contend tolerability will ultimately decide the winners (note plural) in the obesity arena.
Other thoughts:
The hormone space is “hot”. (See #msg-173694133. ) Kallyope is in testing of other hormones and I've speculated that PFE's compound with an undisclosed MOA is likely targets one of these hormones involved in appetite besides GLP1. (see #msg-173593650)
NeuroBo's drug is being dosed SubQ in ph1 and oxyntomodulin is a peptide. It is unlikely this drug could be delivered/effective as an oral agent.
