Overview

AVI-5126 is a phosphorodiamidate morpholino oligomer (PMO) antisense drug developed by AVI BioPharma as part of its NeuGene platform. Its primary mechanism of action is the inhibition of DNA expression, specifically targeting and suppressing the proto-oncogene c-myc, which plays a key role in transplant rejection and vascular proliferative disorders. The drug was investigated for use in preventing coronary artery restenosis—re-narrowing of blood vessels after interventions such as angioplasty or coronary artery bypass graft (CABG) surgery—and was also studied preclinically for delaying corneal allograft rejection by inhibiting c-myc expression. Clinical development reached Phase II trials for coronary artery restenosis but was discontinued[2][4][7]. Preclinical studies demonstrated that AVI-5126 could delay graft rejection in corneal transplantation models without significant toxicity[3][5][6].
