Aim To compare efficacy (intraocular pressure (IOP) reduction) and safety of preservative-free latanoprost (T2345) to benzalkonium chloride (BAK)-preserved latanoprost (BPL; Xalatan) in ocular hypertension (OHT) or primary open angle glaucoma (POAG) patients.

Methods Prospective, international, multicentre, randomised, investigator-masked, parallel–group trial. After a wash-out period, POAG or OHT patients, previously managed by BPL monotherapy, randomly received T2345 or BPL (one drop into the affected eye(s)) once daily from D0 to D84. Change in IOP was measured at 09:00 (±1 h) from D0 to D84 in the worse eye.

Results Mean IOP reduction (D0–D84) was −8.6±2.6 mm Hg (−36%) on T2345 and −9.0±2.4 mm Hg (−38%) on BPL, confirming non-inferiority of T2345 to BPL. Non-inferiority of T2345 was observed from D15. The most frequent ocular adverse event, drug intolerance, was reported in 1 (0.5%) patient on T2345 versus 4 (2.1%) patients on BPL. Moderate to severe conjunctival hyperaemia was less frequent on T2345 than on BPL at D42 (20.2% vs 30.6%; p=0.003) and D84 (21.4% vs 29.1%; p=0.02). Upon instillation, the global subjective ocular symptom score was significantly lower on T2345 than BPL on D42 (0.15 vs 0.41; p=0.001) and D84 (0.18 vs 0.46; p=0.001).

Conclusions Preservative-free latanoprost has the same efficacy as BPL, with improved local tolerance.
