5 Pharmacology and Biochemistry
5.1 Mechanism of Action

MN-305 is a potent and highly-selective full agonist at the serotonin 5-HT1A receptor under development by MediciNova both for the treatment of insomnia, as well as for anxiety disorders such as Generalized Anxiety Disorder (GAD). MN-305 has been evaluated in an extensive preclinical toxicology program which showed no evidence of inducing genetic mutations, immune response or cancer. MN-305 has also proved to be consistently well-tolerated in clinical safety, efficacy and pharmacokinetic studies in over 1,200 subjects.
