Meaning as Regards Beovu Safety Issues by a Comparison of Major Changes Made: "Revised: 2/2022" vs. "Revised: 6/2020"
(Posted by Tom Lamb at Drug Injury Watch)
Beovu (brolucizumab) was approved by the FDA in 2019 as a treatment for neovascular (wet) age-related macular degeneration (AMD). Since then, there have been reported cases of Beovu eye-related side effects such as retinal vasculitis, retinal vascular occlusion, or retinal artery occlusion leading to vision loss. We have followed these Beovu safety issues for the past two years here on Drug Injury Watch, with our first article dating back to February 2020 (see: "Beovu Side Effects Include Retinal Vasculitis, Eye Inflammation: Safety Issues For Macular Degeneration Drug").
Most recently we have been watching for a forecasted Beovu label change which would, presumably, add new and updated warnings about Beovu eye-related side effects. Now, in February 2022, there is finally a revised Beovu drug label here in the US.
We use the word "finally" because it was back in May 2021, when Novartis stopped three Beovu clinical trials for safety reasons, that Novartis first said it would update the Beovu drug label (see: "Beovu Vision Loss Side Effects Continue to Plague Novartis, Ending 3 Key Clinical Trials in May 2021"). Further, over in Europe, Novartis sent out a November 2021 “Dear Doctor” Letter about Beovu, which was followed by an MHRA January 2022 Drug Safety Update item for Beovu that stated:
New information on [the Beovu adverse events retinal vasculitis and retinal vascular occlusion], including risk factors and possible mechanism, was considered in a recent European safety review and ophthalmologists were informed of the new recommendations in a letter in November 2021. The product information of [Beovu (brolucizumab)] will also be updated to reflect this information.
You can learn more about this first Beovu drug label change made after what Novartis did and said back in May 2021 by taking a look at this recent Drug Injury Watch article, "Beovu Drug Label Change in December 2021 Adds More Information About Vision Loss Side Effects".

So that people can draw their own conclusions about what this February 2022 Beovu label change means as regards the lingering Beovu safety issues mentioned at the outset, we will present a comparison of the Beovu Prescribing Information "Revised: 2/2022" document (PDF) with the earlier "Revised: 6/2020" version, limited to those three parts identified in the "Recent Major Changes" section of the new 2022 Beovu drug label.
CHANGE (February 2022) -- 5.2 Retinal Vasculitis and/or Retinal Vascular Occlusion
Retinal vasculitis and/or retinal vascular occlusion, typically in the presence of intraocular inflammation, have been reported with the use of BEOVU. These immune mediated adverse events may occur following the first intravitreal injection. Discontinue treatment with BEOVU in patients who develop these events. Patients treated with BEOVU who experience intraocular inflammation may be at risk of developing retinal vasculitis and/or retinal vascular occlusion and should be closely monitored [see Contraindications (4.2) and Adverse Reactions (6.1, 6.2)]. Patients should be instructed to report any change in vision without delay.
COMPARE (June 2020) -- 5.2 Retinal Vasculitis and/or Retinal Vascular Occlusion
Retinal vasculitis and/or retinal vascular occlusion, typically in the presence of intraocular inflammation, have been reported with the use of BEOVU [see Contraindications (4.2) and Adverse Reactions (6.1)]. Patients should be instructed to report any change in vision without delay.
ADDED (February 2022) -- 6.1 Clinical Trials Experience (as a final paragraph, below Table 1)
In a clinical study (MERLIN), patients with nAMD who received BEOVU every 4-week maintenance dosing experienced a higher incidence of intraocular inflammation (including retinal vasculitis) and retinal vascular occlusion than patients who received BEOVU every 8 or 12-week maintenance dosing in the clinical studies (HAWK and HARRIER). The interval between two BEOVU doses during maintenance treatment should not be less than 8 weeks.
CHANGE (February 2022) -- 6.2 Immunogenicity (final two paragraphs)
Anti-brolucizumab antibodies were detected in the pre-treatment sample of 36% to 52% of treatment naive patients. After initiation of dosing, anti-brolucizumab antibodies were detected in at least one serum sample in 53% to 67% of patients treated with BEOVU. Intraocular inflammation was observed in 6% of patients with anti-brolucizumab antibodies detected during dosing with BEOVU. Retinal vasculitis and/or retinal vascular occlusion, typically in the presence of intraocular inflammation, are immune mediated adverse events related to exposure to BEOVU. This treatment emergent antibody response may develop following the first intravitreal injection.
Anti-brolucizumab antibodies were not associated with an impact on clinical efficacy.
COMPARE (June 2020) -- 6.2 Immunogenicity (final two paragraphs)
Anti-brolucizumab antibodies were detected in the pre-treatment sample of 36% to 52% of treatment naive patients. After initiation of dosing, anti-brolucizumab antibodies were detected in at least one serum sample in 53% to 67% of patients treated with BEOVU. Intraocular inflammation was observed in 6% of patients with anti-brolucizumab antibodies detected during dosing with BEOVU.
The significance of anti-brolucizumab antibodies on the clinical effectiveness and safety of BEOVU is not known.
We will continue to monitor the drug safety regulatory sector for further developments concerning Beovu eye-related side effects such as retinal vasculitis, retinal vascular occlusion, and retinal artery occlusion.
As we have reported previously, starting in January 2021, Beovu lawsuits have been filed for patients alleging that Novartis failed to warn doctors and patients about these Beovu vision loss side effects in a timely manner.
We continue to investigate Beovu drug injury lawsuits against Novartis where there has been vision loss due to retinal vasculitis, retinal vascular occlusion, or retinal artery occlusion after patients received their Beovu injections.
