`
`DOSAGE AND ADMINISTRATION
`
`
`2.1
`General Dosing Information
`For ophthalmic intravitreal injection. BEOVU must be administered by a qualified physician.
`
`Neovascular (Wet) Age-Related Macular Degeneration (AMD)
`2.2
`The recommended dose for BEOVU is 6 mg (0.05 mL of 120 mg/mL solution) administered by intravitreal injection
`monthly (approximately every 25-31 days) for the first three doses, followed by 6 mg (0.05 mL) by intravitreal injection
`once every 8-12 weeks.
`
`2.3
`
`Preparation for Administration
`
`Store BEOVU in the refrigerator between 2 to 8°C (36 to 46°F); do not
`freeze. Keep the vial in the outer carton to protect from light.
`
`Prior to use, the unopened glass vial of BEOVU may be kept at room
`temperature, 20 to 25°C (68 to 77°F) for up to 24 hours. After opening
`the glass vial, proceed under aseptic conditions.
`
`BEOVU is a clear to slightly opalescent and colorless to slightly
`brownish-yellow solution.
`
`BEOVU should be inspected visually upon removal from the refrigerator
`and prior to administration. If particulates, cloudiness, or discoloration
`are visible, the glass vial must not be used.
`
`The BEOVU kit includes the sterile glass vial and filter needle which are
`for single use only. Do not use if the packaging, vial and/or filter needle

`
`Injection Procedure
`2.4
`Ensure that the injection is given immediately after preparation of the dose.
`The intravitreal injection procedure must be carried out under aseptic conditions, which includes the use of surgical hand
`disinfection, sterile gloves, a sterile drape and a sterile eyelid speculum (or equivalent), and the availability of sterile
`paracentesis equipment (if required). Adequate anesthesia and a broad-spectrum topical microbicide to disinfect the
`periocular skin, eyelid, and ocular surface should be administered prior to the injection.
`Inject slowly until the rubber stopper reaches the end of the syringe to deliver the volume of 0.05 mL. Confirm delivery of
`the full dose by checking that the rubber stopper has reached the end of the syringe barrel.
`Immediately following the intravitreal injection, patients should be monitored for elevation in intraocular pressure (IOP).
`Appropriate monitoring may consist of a check for perfusion of the optic nerve head or tonometry. If required, a sterile
`paracentesis needle should be available.
`Following intravitreal injection, patients should be instructed to report any symptoms suggestive of endophthalmitis or
`retinal detachment (e.g., eye pain, redness of the eye, photophobia, blurring of vision) without delay [see Patient
`Counseling Information (17)].
`Each vial should only be used for the treatment of a single eye. If the contralateral eye requires treatment, a new vial
`should be used and the sterile field, syringe, gloves, drapes, eyelid speculum, filter, and injection needles should be
`changed before BEOVU is administered to the other eye.
`Any unused medicinal product or waste material should be disposed of in accordance with local regulations.

`
`CONTRAINDICATIONS
`
`Ocular or Periocular Infections
`4.1
`BEOVU is contraindicated in patients with ocular or periocular infections.
`
`Active Intraocular Inflammation
`4.2
`BEOVU is contraindicated in patients with active intraocular inflammation.
`
`Hypersensitivity
`4.3
`BEOVU is contraindicated in patients with known hypersensitivity to brolucizumab or any of the excipients in BEOVU.
`Hypersensitivity reactions may manifest as rash, pruritus, urticaria, erythema, or severe intraocular inflammation.
`
`5
`
`WARNINGS AND PRECAUTIONS
`
`Endophthalmitis and Retinal Detachments
`5.1
`Intravitreal injections, including those with BEOVU, have been associated with endophthalmitis and retinal detachments
`[see Adverse Reactions (6.1)]. Proper aseptic injection techniques must always be used when administering BEOVU.
`Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay
`and should be managed appropriately [see Dosage and Administration (2.4) and Patient Counseling Information (17)].
`
`Increase in Intraocular Pressure
`5.2
`Acute increases in intraocular pressure (IOP) have been seen within 30 minutes of intravitreal injection including with
`BEOVU [see Adverse Reactions (6.1)]. Sustained IOP increases have also been reported. Both IOP and perfusion of the
`
`optic nerve head must be monitored and managed appropriately [see Dosage and Administration (2.4)].
`
`Thromboembolic Events
`5.3
`Although there was a low rate of arterial thromboembolic events (ATEs) observed in the BEOVU clinical trials, there is a
`potential risk of ATEs following intravitreal use of VEGF inhibitors. Arterial thromboembolic events are defined as
`nonfatal stroke, nonfatal myocardial infarction, or vascular death (including deaths of unknown cause).
`The ATE rate in the two controlled 96-week neovascular AMD studies (HAWK and HARRIER) during the first 96-weeks
`was 4.5% (33 of 730) in the pooled brolucizumab arms compared with 4.7% (34 of 729) in the pooled aflibercept arms
`[see Clinical Studies (14.1)].
`
`ADVERSE REACTIONS
`6
`The following potentially serious adverse reactions are described elsewhere in the labeling:
` Hypersensitivity [see Contraindications (4.3)]
` Endophthalmitis and Retinal Detachments [see Warnings and Precautions (5.1)]
`Increase in intraocular pressure [see Warnings and Precautions (5.2)]
`
` Thromboembolic Events [see Warnings and Precautions (5.3)]
`
`Clinical Trials Experience
`6.1
`Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in one clinical trial
`of a drug cannot be directly compared with rates in the clinical trials of the same or another drug and may not reflect the
`rates observed in practice.

`
`Immunogenicity
`6.2
`As with all therapeutic proteins, there is a potential for an immune response in patients treated with BEOVU. The
`immunogenicity of BEOVU was evaluated in serum samples. The immunogenicity data reflect the percentage of patients
`whose test results were considered positive for antibodies to BEOVU in immunoassays. The detection of an immune
`response is highly dependent on the sensitivity and specificity of the assays used, sample handling, timing of sample

`
`collection, concomitant medications, and underlying disease. For these reasons, comparison of the incidence of antibodies
`to BEOVU with the incidence of antibodies to other products may be misleading.
`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.

`
`USE IN SPECIFIC POPULATIONS
`
`Pregnancy
`8.1
`Risk Summary
`
`There are no adequate and well-controlled studies of BEOVU administration in pregnant women.
`
`Based on the anti-VEGF mechanism of action for brolucizumab [see Clinical Pharmacology (12.1)], treatment with
`BEOVU may pose a risk to human embryo-fetal development. BEOVU should be used during pregnancy only if the
`potential benefit outweighs the potential risk to the fetus.
`All pregnancies have a background risk of birth defect, loss, and other adverse outcomes. The background risk of major
`birth defects and miscarriage for the indicated population is unknown. In the U.S. general population, the estimated
`background risk of major birth defects is 2%-4% and of miscarriage is 15%-20% of clinically recognized pregnancies.
`Data
`Animal Data
`VEGF inhibition has been shown to cause malformations, embryo-fetal resorption, and decreased fetal weight. VEGF
`
`inhibition has also been shown to affect follicular development, corpus luteum function, and fertility.
`
`Lactation
`8.2
`Risk Summary
`There is no information regarding the presence of brolucizumab in human milk, the effects of the drug on the breastfed
`infant, or the effects of the drug on milk production/excretion. Because many drugs are transferred in human milk and
`because of the potential for absorption and adverse reactions in the breastfed child, breastfeeding is not recommended
`during treatment and for at least one month after the last dose when stopping treatment with BEOVU.
`
`Females and Males of Reproductive Potential
`8.3
`Contraception
`Females
`Females of reproductive potential should use highly effective contraception (methods that result in less than 1% pregnancy
`
`rates) during treatment with BEOVU and for at least one month after the last dose when stopping treatment with BEOVU.
`Infertility
`No studies on the effects of brolucizumab on fertility have been conducted and it is not known whether brolucizumab can
`affect reproductive capacity. Based on its anti-VEGF mechanism of action, treatment with BEOVU may pose a risk to
`reproductive capacity.
`
`Pediatric Use
`8.4
`The safety and efficacy of BEOVU in pediatric patients has not been established.

`
`Geriatric Use
`8.5
`In the two Phase 3 clinical studies, approximately 90% (978/1089) of patients randomized to treatment with BEOVU were
`
`≥ 65 years of age and approximately 60% (648/1089) were ≥ 75 years of age. No significant differences in efficacy or
`safety were seen with increasing age in these studies. No dosage regimen adjustment is required in patients 65 years and
`above.
`
`DESCRIPTION
`11
`Brolucizumab-dbll is a recombinant human vascular endothelial growth factor inhibitor. Brolucizumab-dbll is a
`humanized monoclonal single-chain Fv (scFv) antibody fragment. Brolucizumab-dbll has a molecular weight of ~26
`kilodaltons and is produced in Escherichia coli cells by recombinant DNA technology.
`BEOVU (brolucizumab-dbll) injection is a sterile, preservative-free, clear to slightly opalescent, colorless to slightly
`brownish-yellow solution in a single-dose vial for intravitreal administration. Each vial is designed to deliver 0.05 mL of
`solution containing 6 mg brolucizumab-dbll, polysorbate 80 (0.02%), sodium citrate (10 mM), sucrose (5.8%), and Water
`for Injection, USP and with a pH of approximately 7.2.
`
`12
`
`CLINICAL PHARMACOLOGY
`
`12.1 Mechanism of Action
`Brolucizumab is a human VEGF inhibitor. Brolucizumab binds to the three major isoforms of VEGF-A (e.g., VEGF110,
`VEGF121, and VEGF165), thereby preventing interaction with receptors VEGFR-1 and VEGFR-2. By inhibiting VEGF-A,
`brolucizumab suppresses endothelial cell proliferation, neovascularization, and vascular permeability.
`
`Pharmacodynamics
`12.2
`Leakage of blood and fluid from choroidal neovascularization (CNV) may cause retinal thickening or edema. Reductions
`in central retinal subfield thickness (CST) were observed across all treatment arms.
`
`Pharmacokinetics
`12.3
`Following a single intravitreal dose of 6 mg BEOVU to 25 AMD patients, the mean (range) serum Cmax of free
`brolucizumab (unbound to VEGF-A) was 49 ng/mL (9 to 548 ng/mL) and was attained at 24 hours post-dose.
`Brolucizumab concentrations were near or less than 0.5 ng/mL (lower limit of assay quantitation) at approximately 4
`weeks after repeat dose administration and no accumulation in serum was observed in most patients.
`Elimination
`The estimated mean (± standard deviation) systemic half-life of brolucizumab is 4.4 days (± 2.0 days) after a single
`intravitreal dose.
`Metabolism
`Metabolism of brolucizumab has not been fully characterized. However, free brolucizumab is expected to undergo
`metabolism via proteolysis.
`Excretion
`The excretion of brolucizumab has not been fully characterized. However, free brolucizumab is expected to undergo
`target-mediated disposition and/or passive renal excretion.
`Specific Populations
`Following repeat intravitreal dose administration of 6 mg BEOVU, no differences in the systemic pharmacokinetics of
`brolucizumab were observed based on age (50 years and above), sex, or mild to moderate renal impairment (glomerular
`filtration rate (GFR) = 30 to 70 mL/min, estimated using the Modification of Diet in Renal Disease (MDRD) equation).
`The effect of severe renal impairment or any degree of hepatic impairment on the pharmacokinetics of BEOVU is
`unknown. As significant increases in serum brolucizumab exposures are not expected with intravitreal route of
`administration, no dosage adjustment is needed based on renal or hepatic impairment status.

`
`Drug Interaction Studies
`
`No studies evaluating the drug interaction potential of BEOVU have been conducted.
`
`

`
`NONCLINICAL TOXICOLOGY
`
`13.1 Carcinogenesis, Mutagenesis, Impairment of Fertility
`No studies have been conducted on the carcinogenic or mutagenic potential of BEOVU. Based on the anti-VEGF
`mechanism of action, treatment with BEOVU may pose a risk to reproductive capacity [see Use in Specific Populations
`(8.3)].
`
`14
`
`CLINICAL STUDIES
`
`14.1 Neovascular (Wet) Age-Related Macular Degeneration (AMD)
`
`The safety and efficacy of BEOVU were assessed in two randomized, multi-center, double-masked, active-controlled
`studies (HAWK - NCT02307682 and HARRIER - NCT02434328) in patients with neovascular AMD. A total of 1817
`patients were treated in these studies for two years (1088 on brolucizumab and 729 on control). Patient ages ranged from
`50 to 97 years with a mean of 76 years.
`In HAWK, patients were randomized in a 1:1:1 ratio to the following dosing regimens:
`1) brolucizumab 3 mg administered every 8 or 12 weeks after the first 3 monthly doses,
`2) brolucizumab 6 mg administered every 8 or 12 weeks after the first 3 monthly doses,
`3) aflibercept 2 mg administered every 8 weeks after the first 3 monthly doses.
`In HARRIER, patients were randomized in a 1:1 ratio to the following dosing regimens:
`1) brolucizumab 6 mg administered every 8 or 12 weeks after the first 3 monthly doses,
`2) aflibercept 2 mg administered every 8 weeks after the first 3 monthly doses.
`In both studies, after three initial monthly doses (Week 0, 4, and 8), treating physicians decided whether to treat each
`individual patient on an every 8 week or 12 week dosing interval guided by visual and anatomical measures of disease
`activity, although the utility of these measures has not been established. Patients on 12 week dosing intervals could be
`changed based on the same measures to an 8 week schedule after subsequent treatment visits. Any patient placed on an 8
`week schedule, remained on the 8 week dosing interval until the end of the study. Protocol-specified visits in the initial
`three months occurred every 28 ± 3 days followed by every 28 ± 7 days for the remainder of the studies. Baseline
`anatomical measures may have contributed to the regimen selection because the majority of patients on the 12-week
`dosing schedule at the end of the trial had less baseline macular edema and/or smaller baseline lesions.
`
`Both studies demonstrated efficacy in the primary endpoint defined as the change from baseline in Best Corrected Visual
`Acuity (BCVA) at Week 48, measured by the Early Treatment Diabetic Retinopathy Study (ETDRS) Letter Score. In both
`studies, BEOVU treated patients had a similar mean change from baseline in BCVA as the patients treated with
`aflibercept 2 mg (fixed every 8 weeks). Detailed results of both studies are shown in the Table 2 and Figures 5 and 6
`below.

`Figure 6: Mean Change in Visual Acuity From Baseline to Week 96 in HARRIER
`
`Through Week 48, 56% (HAWK) and 51% (HARRIER) of patients remained on BEOVU every 12 weeks. The proportion
`of patients who were maintained on every 12 week dosing through Week 96 was 45% and 39% in HAWK and
`HARRIER, respectively. The probability of remaining on every 12 week dosing from Week 20 to Week 48 was 85% and
`82%, and from Week 48 to Week 96 was 82% and 75% in HAWK and HARRIER, respectively.
`Treatment effects in evaluable subgroups (e.g., age, gender, race, baseline visual acuity) in each study were generally
`consistent with the results in the overall populations.

`
`HOW SUPPLIED/STORAGE AND HANDLING
`
`16.1 How Supplied
`BEOVU (brolucizumab-dbll) injection is supplied as a clear to slightly opalescent and colorless to slightly brownish-
`yellow 6 mg/0.05 mL solution in a single-dose vial. Each BEOVU carton (NDC 0078-0827-61) contains one BEOVU vial
`and one sterile 5 µm blunt filter needle (18-gauge x 1½ inch, 1.2 mm x 40 mm).
`
`Storage and Handling
`16.2
`Refrigerate BEOVU between 2 to 8°C (36 to 46°F). Do not freeze. Store the vial in the outer carton to protect from light.
`Prior to use, the unopened glass vial of BEOVU may be kept at room temperature, 20 to 25°C (68 to 77°F) for up to 24
`hours.
`
`PATIENT COUNSELING INFORMATION
`17
`Endophthalmitis and Retinal Detachments
`Advise patients that in the days following BEOVU administration, patients are at risk of developing endophthalmitis. If
`the eye becomes red, sensitive to light, painful, or develops a change in vision, advise the patient to seek immediate care
`from an ophthalmologist [see Warnings and Precautions (5.1)].
`Patients may experience temporary visual disturbances after an intravitreal injection with BEOVU and the associated eye
`examination [see Adverse Reactions (6.1)]. Advise patients not to drive or use machinery until visual function has
`recovered sufficiently.
