Beovu (brolucizumab) is an injectable medication that treats various eye conditions, including age-related macular degeneration.
Unfortunately, Beovu may cause significant health concerns. Side effects include retinal vasculitis, retinal artery occlusion, blurred vision and eye pain. Novartis, the drug’s manufacturer, initially failed to disclose some of these issues, leading many patients to file lawsuits.
If you’ve experienced Beovu side effects, monitor your symptoms, contact your ophthalmologist and keep records of your treatments.
What Is Beovu, and What Does It Treat?
Beovu is a drug that treats wet age-related macular degeneration (AMD). Health care providers administer the drug via injection. The U.S. Food & Drug Administration (FDA) approved Beovu in 2019.
AMD is a condition that results in central vision loss. Vascular endothelial growth factor (VEGF) is a key component of AMD. VEGF is a protein that promotes irregular blood vessel growth underneath the area of your retina responsible for your central vision.
Beovu is a VEGF inhibitor. By limiting VEGF, Beovu prevents abnormal vessel growth, making it less likely for fluid to leak into your retina.
Beovu vs. Other AMD Treatments
When compared to other AMD drugs like Eylea (aflibercept) and Lucentis (ranibizumab), the benefits and downsides of Beovu vary based on the patient.
Clinical trials showed that people who received Beovu had slightly less improvement in the ability to read letters in a vision exam than those who received Eylea. However, one-third of the Beovu patients had improvements in their ability to see details from a distance compared to one-fourth of Eylea users.
Lucentis differs from Beovu because doctors can administer it via a refillable, surgically implantable device called a port delivery system. Studies also showed Lucentis improved users’ sight by several lines on the eye chart after multiple injections, but the gains reversed over time.
Vision Loss Risks and Inflammatory Side Effects of Beovu
Shortly after Novartis released Beovu, evidence began to surface showing side effects like temporary or permanent vision loss, inflammatory issues and more.
Research in EyeNet Magazine indicated that 10.5% of Beovu patients experienced intraocular inflammation (inflamed tissue in the eye). 81% of these issues happened during the first three months of treatment.
The most common Beovu side effects reported to the U.S. Food and Drug Administration (FDA) were vitreous floaters, impaired vision, blurred vision, eye inflammation and reduced visual acuity.
- Eye floaters: 17.2%
- Visual impairment: 16.1%
- Blurred vision: 14.9%
- Eye inflammation: 13.9%
- Reduced visual acuity: 13.3%
It’s important to tell your doctor immediately if you notice any changes in your vision or experience eye pain. Using drugs like Beovu may also put you at risk for blood clots.
| FDA Adverse Events Reporting System (FAERS) Data for Beovu Side Effects | |
|---|---|
| Total cases reported | 2,758 |
| Severe cases (including deaths) | 2,035 |
| Deaths | 198 |
Retinal Vasculitis
Retinal vasculitis is a condition in which inflammatory changes occur in your retinal arteries or veins. It can cause complications that threaten your vision. Common symptoms include blurred vision, blind spots, flashes, floaters, visual distortions and changes in how you see color.
The condition gets progressively worse. It starts with inflammation and can lead to complications like hemorrhages and retinal detachment if not treated.
Experts have linked Beovu to retinal vasculitis. In 2020, the American Society of Retina Specialists revealed it had received reports of 14 cases of vasculitis among Beovu patients.
Retinal Artery Occlusion
Retinal artery occlusion occurs when cholesterol buildup or a blood clot blocks blood flow to one or more of your retina’s arteries. It is typically painless, but it could cause you to completely lose your vision. You may also experience blind spots, distorted vision or peripheral vision loss.
Evidence suggests that Beovu use may contribute to the development of this condition.
Blurred Vision or Vision Loss
Blurred vision was one of the most common side effects reported by patients who received Beovu injections. The drug’s manufacturer, Novartis, reported that 10% of patients experienced blurred vision.
Novartis also revealed that 1% of patients reported vision loss.
Eye Pain, Redness and Inflammation
Eye pain, redness and inflammation are common after receiving a Beovu injection. Novartis reported that 5% of Beovu patients experienced eye pain.
The manufacturer also suggests that Beovu users report any eye pain or redness to their doctors immediately. These symptoms can indicate retinal detachment or inflammation caused by infection.
Studies into the effectiveness of Beovu found that side effects of the medication included increased eye inflammation. One study determined that inflammation quickly resolved when doctors treated patients with a steroid medication.
Permanent Blindness
Many of the potential Beovu side effects, including retinal vasculitis and retinal artery occlusion, can result in severe and permanent blindness.
A study published in the American Journal of Ophthalmology revealed that retinal vasculitis leading to severe vision loss had occurred after multiple Beovu injections. Researchers concluded that “it is not always possible to guarantee safety, even if the patient has tolerated previous brolucizumab treatments without incidents.”
Timeline of Beovu Safety Warnings and Updates
The FDA originally approved the use of Beovu to treat wet AMD, but quickly followed that decision with some key safety warnings and updates.
-
October 2019:
The FDA authorized Beovu injections to treat patients with wet AMD. The agency granted approval based on evidence from two clinical trials that included 1,459 patients between the ages of 50 and 97 who had received wet AMD diagnoses.
-
Early 2020:
Patients began experiencing adverse side effects. Concerns mounted about a potential link between Beovu use and the development of irreversible retinal vascular occlusion or retinal vasculitis, potentially leading to vision loss. An American Journal of Ophthalmology editorial urged doctors to stop prescribing the medication until researchers determine the causes of Beovu’s adverse events.
-
April 2020:
Novartis responded to the complaints of vasculitis and occlusion by funding a separate safety review. In response to the safety study revealing new potential risk factors, Novartis indicated it would update prescribing information to include warnings about an increased risk of “retinal vasculitis and/or retinal vascular occlusion that may result in severe vision loss.”
-
June 2020:
Novartis announced that the FDA had approved an updated safety label warning detailing the risk of adverse events.
The safety label warning update came too late for many patients. Some patients are pursuing Beovu lawsuits to hold Novartis responsible for releasing a dangerous product and failing to alert patients about the medication’s risks.
Who May Be at Greater Risk for Complications?
Some patients face a greater risk of complications from Beovu use than others. This includes patients with:
- A history of anti-VEGF injections
- A history of intraocular inflammation
- Hypersensitivity to Beovu or any of its ingredients
- Infections in or around the eyes
- More fragile retinal blood vessels due to age
- Underlying autoimmune or vascular conditions
Novartis recommends that patients who are pregnant or breastfeeding exercise caution when using Beovu. The manufacturer also cites potential reproductive risks and mentions that it has not studied Beovu for pediatric use.
What To Do if You’ve Experienced Beovu Side Effects
If you have experienced side effects associated with Beovu, there are a few key steps to take.
- Monitor your symptoms: Common symptoms of Beovu complications include blurred vision, eye pain and sudden vision loss. Monitor yourself for any of these concerns.
- Call an ophthalmologist immediately if symptoms arise: Alert your ophthalmologist to any symptoms you experience to ensure that you receive proper treatment.
- Ask for imaging to detect inflammation: Tests like optical coherence tomography (OCT) or fluorescein angiography can help detect and document potential complications in your retina.
- Report adverse events to the FDA (MedWatch): It's important that the FDA has accurate information about medication side effects to issue warnings to others and make decisions on regulatory actions.
- Save all treatment records and follow-up documentation: If you want to pursue a claim against Novartis for Beovu side effects, hold onto documentation showing that you developed complications and received treatment.
Consider contacting an attorney to see if you can take legal action for your Boveau side effects. Attorneys have filed many lawsuits against Novartis for injuries the medication caused and for the company’s failure to provide adequate warnings about its risks.
