Clinical Trial Summary

Type 1 retinopathy of prematurity in zone I represents the most severe type of ROP and has the worst prognosis. It is unknown whether low-dose bevacizumab will be successful in these severe cases. Also unknown is the timing and extent of peripheral retinal vascularization after low-dose bevacizumab compared with the standard dose. The current study will evaluate whether doses of 0.063 mg and 0.25mg are effective as treatment for type 1 ROP, with ROP and retinal vessels all in zone I.

Description:

Infants with type 1 ROP and no prior treatment for ROP will be randomly assigned (1:1) to treatment with either intravitreous bevacizumab 0.063 mg or either intravitreous bevacizumab 0.25 mg. Study exams will be at 1 day, 4 days (if no improvement on day 1), 1, 2, 3, and 4 weeks, and at 2 and 4-months post-treatment (and re-treatment when indicated). Additional study exams will occur at adjusted age 6 and 12 months. Non-study examinations will be at clinician discretion and are likely to occur more often. The primary outcome will be treatment success within each dose group, defined as improvement by the day 4 exam and no recurrence of type 1 ROP or severe neovascularization requiring additional treatment within 4 weeks of injection. Important secondary outcomes include safety and efficacy. refractive outcomes, and the extent of retinal vascularization at 2 and 4 months post-injection between the two dose groups.

1. Previous treatment for ROP

2. Stage 4 or 5 ROP in either eye

3. Treatment could not be done within 2 days of diagnosis of type 1 ROP

5. Transfer to another hospital anticipated within the next 4 weeks where exams by study-certified examiners are not available. If hospital discharge is anticipated within the next 4 weeks, parents unable or unwilling to return to the PEDIG site for outpatient follow-up visits.

6. Active ocular infection or purulent nasolacrimal duct obstruction in either eye One eye will be excluded, and other eye may be eligible, if either of the following are

present:

• Premature Birth
• Retinal Diseases
• Retinopathy of Prematurity

Intervention

Drug:
• Bevacizumab
All participants will receive a single intravitreal injection of bevacizumab in one or both eyes following enrollment into the study. The injection/s should be given as soon as possible but no later than 2 days after the diagnosis of type 1 ROP meeting all of the inclusion criteria and none of the exclusion criteria. Eyes meeting eligibility criteria will receive a single dose of 0.063 mg or 0.25mg bevacizumab provided by the pharmacy at the investigator's institution.
