What You Need to Know Before You Apply

What is the purpose of this trial?

This trial explores whether two different doses of bevacizumab, a medication injected into the eye, can effectively treat type 1 retinopathy of prematurity (ROP), a severe eye condition in premature infants. The study targets babies with type 1 ROP in zone I, the most serious form affecting the central retina. Eligible infants should weigh less than 1251 grams at birth and have been diagnosed with type 1 ROP in zone I within the past two days. As a Phase 2 trial, this research measures the treatment's effectiveness in an initial, smaller group, offering a chance to contribute to important early findings.

Will I have to stop taking my current medications?

The trial information does not specify whether participants need to stop taking their current medications.

Is there any evidence suggesting that this trial's treatments are likely to be safe?

Research has shown that using bevacizumab as an eye injection is generally safe for treating retinopathy of prematurity (ROP). One study on babies with ROP found that bevacizumab worked well and was well-tolerated, with no major safety concerns.

Compared to similar treatments, bevacizumab often required fewer follow-up treatments, indicating effective results without additional issues. Importantly, studies reviewed have reported no severe side effects, which reassures those considering this treatment.

The FDA has also approved bevacizumab for other eye conditions, supporting its overall safety. While this trial continues to collect more data, existing studies provide strong evidence that bevacizumab is a safe choice for treating ROP. ^{1 2 3 4 5}

Why are researchers excited about this trial's treatment?

Researchers are excited about bevacizumab for retinopathy of prematurity (ROP) because it offers a targeted approach by inhibiting vascular endothelial growth factor (VEGF), which is crucial in the abnormal blood vessel growth seen in ROP. Unlike the standard treatments, such as laser therapy that can damage retinal tissue, bevacizumab is administered as an intravitreal injection, potentially preserving more of the infant's vision. Additionally, with two different dosage options—0.063 mg and 0.25 mg—researchers hope to find the most effective and safest dose, offering more tailored treatment options for affected infants.

What evidence suggests that bevacizumab might be an effective treatment for retinopathy of prematurity?

Research has shown that bevacizumab effectively treats retinopathy of prematurity (ROP), a serious eye condition in premature babies. One study found that 85.13% of eyes with ROP improved after a bevacizumab injection, with the most severe cases (zone I stage 3+) showing a 100% improvement. Another study demonstrated that even a low dose of 0.03 mg effectively treated type 1 ROP in all tested eyes. In this trial, participants will receive either a 0.063 mg or 0.25 mg dose of bevacizumab, potentially offering promising treatment options for severe ROP cases. ^{4 6 7 8 9}

Published Research Related to This Trial

Intravitreal injection of bevacizumab is a safe and effective treatment for aggressive posterior retinopathy of prematurity (APROP), as demonstrated in a case involving a premature infant with significant retinal improvements after treatment.

While tissue contraction can occur as a side effect, localized tractional retinal detachment can be effectively managed with lens-sparing vitrectomy, allowing for successful retinal reattachment.

Infants with treatment-warranted retinopathy of prematurity (TW-ROP) who received intravitreal bevacizumab (IVB) injections had significantly fewer diagnoses and readmissions compared to those treated with diode laser photocoagulation (DLP), suggesting better immediate outcomes with IVB.

At an average follow-up of 20 months, there was no significant difference in neurodevelopmental delay between the two treatment groups, indicating that systemic morbidity may be similar for both IVB and DLP treatments.

Intravitreal bevacizumab (Avastin) was found to enter the systemic circulation and cause long-lasting changes in lung matrix metalloproteinases (MMPs) and their inhibitors in neonatal rats, suggesting potential systemic effects beyond its local application.

The treatment with Avastin led to increased levels of MMP-2 and MMP-9 in the lungs of rats exposed to hyperoxia and intermittent hypoxia, which may contribute to impaired lung development and conditions like bronchopulmonary dysplasia.
