Omeros Corporation Awarded $6.69 Million Grant from the National Institute on Drug Abuse for its OMS527 Addiction Program
To advance NIDA’s urgent medication development priorities for substance use disorders, Omeros submitted a grant application in 2022 to assess the potential of PDE7 inhibition as a treatment for CUD. Following peer review including leaders in the field from academia and industry, grant funding was awarded on
Omeros discovered the role of PDE7 in addiction and compulsion and elucidated the associated mechanism of action of PDE7 inhibition. PDE7 directly affects dopaminergic pathways in the brain. The dopamine axis is central to all addiction and compulsive disorders, and PDE7 inhibition modulates dopamine signaling in key areas of the brain responsible for these disorders. In animal models of addiction across cocaine, opioids, nicotine and alcohol, Omeros’ PDE7 inhibitors have been shown to reduce both craving and relapse as well as demonstrating benefit in a well-established animal model of binge eating. OMS527 has successfully completed both the single-ascending- and multiple-ascending-dose components of a Phase 1 clinical trial in healthy subjects; the drug was well tolerated with no safety signal of concern.
“We are very pleased to work with our colleagues at NIDA to accelerate the development of OMS527, our PDE7 inhibitor program,” said
Cocaine use disorder is a medical condition characterized by compulsive cocaine use despite adverse consequences and the development of a dysphoric state associated with drug withdrawal, which can trigger the resumption of drug use. An estimated 1.4 million people in the

Omeros is an innovative biopharmaceutical company committed to discovering, developing and commercializing small-molecule and protein therapeutics for large-market and orphan indications targeting immunologic disorders including complement-mediated diseases, cancers, and addictive and compulsive disorders. Omeros’ lead MASP-2 inhibitor narsoplimab targets the lectin pathway of complement and is the subject of a biologics license application pending before FDA for the treatment of hematopoietic stem cell transplant-associated thrombotic microangiopathy (TA-TMA). Narsoplimab is also in multiple late-stage clinical development programs focused on other complement-mediated disorders, including IgA nephropathy, COVID-19, and atypical hemolytic uremic syndrome. Omeros’ long-acting MASP-2 inhibitor OMS1029 is currently in a Phase 1 clinical trial. OMS906, Omeros’ inhibitor of MASP-3, the key activator of the alternative pathway of complement, is advancing in clinical programs for paroxysmal nocturnal hemoglobinuria (PNH), complement 3 (C3) glomerulopathy and other related indications.
