INTRODUCTIONMultidrug regimens for glaucoma treatment often result in adherence issues due to inconvenience; these issues may be improved with fixed-dose combination drugs. The ophthalmic solution of ripasudil-brimonidine fixed-dose combination (RBFC; K-232) is the first treatment combining a Rho kinase inhibitor and an α₂-adrenoceptor agonist, and has demonstrated ability to lower intraocular pressure (IOP) and have various effects on conjunctival hyperemia and corneal endothelial cell morphology. This study evaluates the pharmacologic effects of RBFC treatment versus its separate components-ripasudil or brimonidine.METHODSThis single-center, prospective, randomized, open-label, blinded endpoint study with 3 × 3 crossover design randomly assigned healthy adult men to three groups (1:1:1) to undergo consecutive 8-day administration phases (with drug-free intervals of at least 5 days). Subjects received twice-daily instillation of RBFC → ripasudil → brimonidine (group A), ripasudil → brimonidine → RBFC (group B), or brimonidine → RBFC → ripasudil (group C). Endpoints included change in IOP, severity of conjunctival hyperemia, corneal endothelial cell morphology, pupil diameter, and pharmacokinetics.RESULTSEighteen subjects were assigned in total (six to each group). RBFC significantly reduced IOP from baseline at 1 h post-instillation on days 1 and 8 (12.7 vs. 9.1 and 9.0 mmHg, respectively; both P < 0.001), and provided significantly greater IOP reductions than ripasudil or brimonidine at several time points. The most common adverse drug reaction with all three treatments was mild conjunctival hyperemia, which transiently increased in severity with RBFC or ripasudil, peaking at 15 min post-instillation. In post hoc analyses, conjunctival hyperemia scores were lower with RBFC than with ripasudil at several time points. Transient morphologic changes in corneal endothelial cells occurred for up to several hours with RBFC or ripasudil, but not with brimonidine. Pupil diameter did not change with RBFC.CONCLUSIONRBFC significantly reduced IOP compared with each agent alone. A combination of each agent's pharmacologic profile was observed in that of RBFC.TRIAL REGISTRATIONJapan Registry of Clinical Trials; Registration No. jRCT2080225220.

Ripasudil–Brimonidine Fixed-Dose Combination vs Ripasudil or Brimonidine: Two Phase 3 Randomized Clinical Trials

PURPOSETo confirm the superiority of the intraocular pressure (IOP)-lowering effect of the ripasudil-brimonidine fixed-dose combination (RBFC, K-232) to ripasudil 0.4% or brimonidine 0.1% ophthalmic solution.DESIGNTwo prospective multicenter, randomized, double- or single-masked, active-controlled, phase 3 trials.METHODSPatients with primary open-angle glaucoma or ocular hypertension whose IOP level was ≥18 mm Hg during treatment with ripasudil or brimonidine alone were randomized to 2 groups (RBFC and ripasudil) in a 1:1 ratio in the ripasudil-controlled trial and to 3 groups (RBFC, brimonidine, and ripasudil-brimonidine combination) in a 2:2:1 ratio in the brimonidine-controlled trial. The allocated study drugs were instilled twice daily for 8 weeks. The primary efficacy endpoint was the change in IOP 2 hours after instillation (11 AM) from the baseline to weeks 4, 6, and 8.RESULTSThere were 206 patients randomized in the ripasudil-controlled trial. Changes in IOP were -2.6 and -1.2 mm Hg in the RBFC and ripasudil groups, respectively, with a difference of -1.4 mm Hg (95% CI = -1.8 to -1.0 mm Hg; P < .001). There were 282 randomized patients in the brimonidine-controlled trial. Changes in IOP were -3.4 and -1.5 mm Hg in the RBFC and brimonidine groups, respectively, with a difference of -1.8 mm Hg (95% CI = -2.3 to -1.4 mm Hg; P < .001). The most frequent adverse event was conjunctival hyperemia.CONCLUSIONSThe IOP-lowering effect of RBFC was superior to that of ripasudil or brimonidine.

AIMSScreening and partial characterization of a bacteriocin produced by Pediococcus pentosaceus K23-2 isolated from Kimchi, a traditional Korean fermented vegetable.METHODS AND RESULTSA total of 1000 lactic acid bacteria were isolated from various Kimchi samples and screened for the production of bacteriocin. Pediocin K23-2, a bacteriocin produced by the Pediococcus pentosaceus K23-2 strain, showed strong inhibitory activity against Listeria monocytogenes. The bacteriocin activity remained unchanged after 15 min of heat treatment at 121 degrees C or exposure to organic solvents; however, it diminished after treatment with proteolytic enzymes. The bacteriocin was maximally produced at 37 degrees C, when the pH of the culture broth was maintained at 5.0 during the fermentation, although the optimum pH for growth was 7.0. The molecular weight of the bacteriocin was about 5 kDa according to a tricine SDS-PAGE analysis.CONCLUSIONSPediococcus pentosaceus K23-2 isolated from Kimchi produces a bacteriocin, which shares similar characteristics to the Class IIa bacteriocins. The bacteriocin is heat stable and shows wide antimicrobial activity against Gram-positive bacteria, especially L. monocytogenes.SIGNIFICANCE AND IMPACT OF THE STUDYPediocin K23-2 and pediocin K23-2-producing P. pentosaceus K23-2 could potentially be used in the food and feed industries as natural biopreservatives, and for probiotic application to humans or livestock.
