SafetyTreatment-emergent adverse events (TEAEs) in the pooled population were mostly mild to moderate in nature and resolved without any treatment. Conjunctival hyperemia was the most frequent ocular AE that occurred in 30 (5.7%) and 19 (3.6%) patients in the OTX-101 and vehicle groups, respectively. Instillation site pain (typically described as mild stinging and/or burning after each instillation) was the most frequent administration site TEAE, reported by 114 (21.8%) and 21 (4.0%) patients in the OTX-101 and vehicle groups, respectively (Table (Table3).3). Other administration site TEAEs occurred in less than 1% of the study population and were similar between the 2 groups.
