Condition(s) targeted: Retinopathy of Prematurity

Intervention: Propranolol eye drops (Drug)

Phase: Phase 2

Status: Completed

Summary

The aim of the present study is to evaluate the safety and efficacy of propranolol eye drops in preterm newborns with a precocious stage of retinopathy of prematurity (ROP). Preterm newborns (gestational age 23-32 weeks) with a stage 2 ROP (zone II without plus) will receive propranolol eye drops treatment until retinal vascularization will be completed. Propranolol concentrations will be measured on dried blood spots during the first 3 days of treatment and at the steady state. Cardiovascular and respiratory parameters will be continuously monitored. Blood samplings checking metabolic, renal and liver functions will be performed periodically, as well as cardiac function, in order to verify the treatment safety. Serial ophthalmological evaluations will be planned to monitor the efficacy of the treatment, the ROP progression and the possible complications.

Clinical Details

Official title: Safety and Efficacy of Propranolol Eye Drops in Newborns With Retinopathy of Premature (DROP-PROP)

Study design: Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Open Label, Primary Purpose: Treatment

Primary outcome:

Incidence rate of progression from stage 2 ROP to more severe stage ROP (stage 2 or 3 with plus, stage 4 and stage 5)

Number of newborns who progress to Stage 4 or 5 ROP with total or partial retinal detachment

Number of newborns who need laser treatment

Number of newborns who need rescue treatment with bevacizumab

Number of newborns who need vitrectomy

Collection of adverse events due to eye drop propranolol treatment
