Study information
Scientific title
Evaluating the safety and efficacy of propranolol administration in preterm newborns suffering from a precocious phase of retinopathy of prematurity (ROP): A randomised controlled trial
Acronym
PROP-ROP
Study hypothesis
To evaluate the safety of propranolol administration in preterm newborns suffering from a precocious phase of retinopathy of prematurity (ROP) and its efficacy to reduce the disease progression, the incidence retinal detachment and of blindness, by suppressing the neovascular phase of ROP compared to a control group receiving conventional treatment.
Ethics approval
The Centre Research Ethics Board (Comitato Etico Sperimentazione dei Medicinali [CESM]) of A. Meyer University Children's Hospital, Florence and of the Institute of Pediatrics and Neonatology, Fondazione IRCCS Ospedale Maggiore Policlinico, Mangiagalli e Regina Elena, University of Milan approved on the 14th of January 2010 (ref: 277/2010).

Condition
Retinopathy of prematurity (ROP), the leading cause of blindness in children
Intervention
Parents of newborns who meet the inclusion criteria will be approached by the study investigator/nurse, informed of the study. Signed written informed consent will be obtained.
Patients will be randomised to receive:
1. Intervention: Administration of propranolol. Dosage of 0.5mg/Kg orally, every 6 hours in the treated arm. This treatment will be continued until vascularization of retina will be complete.
2. Control: Treatment as usual. Standard laser therapy.

Primary outcome measures
To evaluate the safety of propranolol administration in preterm newborns suffering from a precocious phase of ROP.
In order to evaluate the safety of this treatment, heart frequency, blood pressure, oxygen saturation, respiratory support, will be continuously monitored.
Blood samplings to check renal, liver and metabolic balance will be performed weekly for the first 4 weeks of treatment.
Secondary outcome measures
To evaluate the safety of propranolol administration in preterm newborns suffering from a precocious phase of ROP.
In order to evaluate the efficacy of this treatment, serial ophthalmologic evaluations will be planned at different intervals according to the severity of ROP. The efficacy will be evaluated comparing the different incidence of the progression of ROP to stages 3 or to retinal detachment, the different incidence of laser treatment, the different incidence of vitrectomy, between the two groups.
The follow-up planned at 1, 4 and half, 6, 12, 18 and 24 months, will allow to evaluate the functional outcome.
Visual acuity will be evaluate at 1, 4 and half, and 12 months of corrected age.

Participant inclusion criteria
The studied population consists of preterm infants delivered at less than 32 weeks gestational age admitted to the Neonatal Intensive Care Unit at the A. Meyer University Children's Hospital, Florence and at the Institute of Pediatrics and Neonatology, Fondazione IRCCS Ospedale Maggiore Policlinico, Mangiagalli e Regina Elena, University of Milan.
1. Infants who have been screened for ROP (≥32 weeks gestation) who developed zone II-III, stage 2 ROP without plus.
2. Informed Consent from a parent

Participant exclusion criteria
1. Newborns with congenital cardiovascular anomalies, renal failure, cerebral haemorrhage, which contraindicate the use of beta-blockers
2. Newborns with ROP stages more advances than zone II-III, stage 2 ROP without plus
3. Informed Consent from a parent refused. This will mean that an infant automatically will receive standard laser therapy. No data will be used from an infant without Informed Consent.
