Omeros Reports Additional Positive Results from Phase 1 OMS824 Clinical Trial

Omeros Corporation OMER today announced positive data from the Company's Phase 1 clinical trial evaluating the pharmacokinetics of OMS824, the lead compound in Omeros' phosphodiesterase 10 (PDE10) program, further supporting that OMS824 can achieve superior target engagement with lesser side effects compared to other PDE10 inhibitors in development. With these data and the previously announced encouraging results from the OMS824 positron emission tomography (PET) clinical trial, Omeros is advancing OMS824 into Phase 2 clinical programs. OMS824 selectively inhibits PDE10, an enzyme expressed in areas of the brain linked to a wide range of diseases that affect cognition, including Huntington's disease and schizophrenia. The OMS824 Phase 1 clinical trial included single- and multiple-dose escalation studies that enrolled 100 healthy male subjects: 60 subjects received a single dose of OMS824, 24 subjects received multiple doses for seven to 10 days, and 16 subjects received placebo. The data announced today are at the highest multiple-dose level administered and, at this dose, OMS824 was well tolerated and the only apparent drug-related adverse events were mild.
