Our phosphodiesterase 7, or PDE7, program is based on our discoveries of previously unknown links between PDE7 and any addiction or compulsive disorder and between PDE7 and any movement disorders, such as Parkinson’s disease. PDE7 appears to modulate the dopaminergic system, which plays a significant role in regulating both addiction and movement. We believe that PDE7 inhibitors could be effective therapeutics for the treatment of addiction and compulsive disorders as well as for movement disorders. Data generated in preclinical studies support the use of PDE7 inhibitors in both of these therapeutic areas.
In our PDE7 program, we are developing proprietary compounds to treat addiction and compulsive disorders as well as movement disorders. A Phase 1 single-ascending- and multiple-ascending-dose clinical trial is underway and designed to assess safety and pharmacokinetics in healthy subjects. Following Phase 1 completion, if successful, we plan to conduct our initial OMS527 Phase 2 clinical trial in patients with nicotine addiction.
As of February 16, 2018, we owned two issued patents and one pending patent applications in the U.S., and 22 issued patents and 10 pending patent applications in foreign markets directed to our discoveries linking PDE7 to movement disorders, as well as one issued patent and two pending patent applications in the U.S., and eight issued patents and 23 pending patent applications in foreign markets directed to the link between PDE7 and addiction and compulsive disorders. Additionally, we exclusively control rights to three issued U.S. patents and 58 issued and four pending patent applications in foreign markets that are directed to proprietary PDE7 inhibitors.
