Latanoprostene bunod (LBN) ophthalmic solution 0.024% is a novel, once-daily, nitric oxide-donating prostaglandin analogue for the lowering of intraocular pressure (IOP) in patients with open-angle glaucoma and ocular hypertension. The IOP-lowering actions of LBN are mediated by dual mechanisms of the molecule for increasing aqueous humour outflow. The prostaglandin analogue moiety (latanoprost acid) increases uveoscleral outflow, whereas nitric oxide, released by the nitric oxide-donating moiety (butanediol mononitrate), increases outflow through the trabecular meshwork and the Schlemm's canal. The clinical efficacy and safety of LBN 0.024% in patients with open-angle glaucoma or ocular hypertension were established in two similarly designed, double-masked, pivotal phase 3 studies, APOLLO and LUNAR, the pooled three-month efficacy phase of which demonstrated significantly greater IOP-lowering of once-daily LBN 0.024% over twice-daily timolol 0.5% at all time points. Additional support for the IOP-lowering effects of LBN 0.024% was provided by two phase 2 studies in patients with open-angle glaucoma or ocular hypertension (a dose ranging study versus latanoprost and a 24-hour IOP crossover study versus timolol) and a phase 1 study of healthy volunteers with IOP in the normal range. In addition, long-term efficacy and safety were demonstrated in the open-label safety-extension phases of the phase 3 pivotal studies and a phase 3 52-week open-label study of patients with open-angle glaucoma (including normal-tension glaucoma) or ocular hypertension. In conclusion, LBN 0.024% has demonstrated both short-term and long-term IOP-lowering efficacy in patients with open-angle glaucoma or ocular hypertension, including in healthy volunteers and patients with IOP in the normal range, without apparent clinically-limiting safety or tolerability concerns.
