Abstract
INTRODUCTION: Intraocular pressure (IOP)-lowering has been demonstrated to slow the progression or onset of visual field loss in open-angle glaucoma (OAG) or ocular hypertension (OHT). Pharmacological lowering of IOP is the most common initial intervention in patients with OAG or OHT, however, many patients will require more than one therapy to achieve target IOP. Latanoprostene bunod is a novel nitric oxide (NO)-donating prostaglandin F2α analog for the reduction of IOP. Areas covered: Current knowledge concerning the mechanism of action of latanoprostene bunod is presented. Additionally, clinical safety and efficacy data from published Phase 1 (KRONUS), Phase 2 (VOYAGER, CONSTELLATION) and Phase 3 (APOLLO, LUNAR, JUPITER) studies are reviewed. Expert opinion: Latanoprostene bunod is a dual mechanism, dual pathway molecule, consisting of latanoprost acid, which is known to enhance uveoscleral (unconventional) outflow by upregulating matrix metalloproteinase expression and remodeling of the ciliary muscle's extracellular matrix, linked to an NO-donating moiety, which enhances trabecular meshwork/Schlemm's canal (conventional) outflow by inducing cytoskeletal relaxation via the soluble guanylyl cyclase-cyclic guanosine monophosphate (sGC-cGMP) signaling pathway. Latanoprostene bunod 0.024% solution applied topically once daily appears more effective in reducing IOP in OHT and OAG subjects than either latanoprost or timolol, with a side effect profile similar to that of latanoprost.
