IZERVAY is a complement inhibitor indicated for the treatment of geographic atrophy (GA) secondary to age-related macular degeneration (AMD) (1).

2 DOSAGE AND ADMINISTRATION

The recommended dose for IZERVAY is 2 mg (0.1 mL of 20 mg/mL solution) administered by intravitreal injection to each affected eye once monthly (approximately 28 ± 7 days) for up to 12 months (2.2).

2.1 General Dosing Information

IZERVAY must be administered by a qualified physician.

2.2 Recommended Dosage

The recommended dose for IZERVAY is 2 mg (0.1 mL of 20 mg/mL solution) administered by intravitreal injection to each affected eye once monthly (approximately every 28 ± 7 days) for up to 12 months.

2.3 Preparation for Administration

Important information you should know before you begin:

  • Read all the instructions carefully before using IZERVAY.
  • The IZERVAY kit includes a glass vial, filter needle, and an empty syringe. The glass vial, filter needle, and empty syringe are for single use only.
  • Store IZERVAY in the refrigerator at temperatures between 2ºC to 8ºC (36ºF to 46ºF). Do not freeze. Do not shake.
  • Prior to use, allow IZERVAY to reach room temperature, 20⁰C to 25⁰C (68⁰F to 77⁰F). The IZERVAY vial may be kept at room temperature for up to 24 hours. Keep the vial in the original carton to protect from light.
  • Use aseptic technique to carry out the preparation of the intravitreal injection.
  • Each vial should only be used for the treatment of a single eye.

Step 1: Gather Supplies

 

Gather the following supplies (see Figure A ):

  • a.One IZERVAY vial (included)
  • b.One sterile 5-micron filter needle 19-gauge x 1½ inch (included)
  • c.One sterile 1 mL Luer lock syringe with a 0.1 mL dose mark (included)
  • d.One sterile injection needle 30‑gauge x ½ inch (not included)

    NOTE: a 30-gauge injection needle is recommended to avoid increased injection forces that could be experienced with smaller diameter needles.

  • e.Alcohol swab (not included)

2.4 Injection Procedure

Only 0.1 mL (2 mg) should be administered to deliver a single dose. Any excess volume should be disposed.

Prior to the intravitreal injection, patients should be monitored for elevated intraocular pressure (IOP) using tonometry [see Warnings and Precautions (5.3)]. If necessary, ocular hypotensive medication can be given to lower the IOP.

The intravitreal injection procedure must be carried out under controlled aseptic conditions, which includes the use of surgical hand disinfection, sterile gloves, a sterile drape, and a sterile eyelid speculum (or equivalent). Adequate anesthesia and a broad-spectrum topical microbicide should be given prior to the injection.

Inject slowly until the rubber stopper reaches the end of the syringe to deliver the volume of 0.1 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.

Following intravitreal injection, patients should be instructed to report any symptoms suggestive of endophthalmitis (e.g., eye pain, redness of the eye, photophobia, blurring of vision) without delay [see Patient Counseling Information (17)].

Each vial and syringe should only be used for the treatment of a single eye. If the contralateral eye requires treatment, a new vial and syringe should be used and the sterile field, syringe, gloves, drapes, eyelid speculum, filter needle, and injection needle should be changed before IZERVAY is administered to the other eye. Repeat the same procedure steps as above.

Any unused medicinal product or waste material should be disposed of in accordance with local regulations.

3 DOSAGE FORMS AND STRENGTHS

Intravitreal solution: 20 mg/mL clear to slightly opalescent, colorless to slightly yellow solution in a single-dose vial.

Intravitreal solution: 20 mg/mL in a single-dose vial (3).

4 CONTRAINDICATIONS

  • Ocular or periocular infections (4.1).
  • Active intraocular inflammation (4.2).

4.1 Ocular or Periocular Infections

IZERVAY is contraindicated in patients with ocular or periocular infections.

4.2 Active Intraocular Inflammation

IZERVAY is contraindicated in patients with active intraocular inflammation.

5 WARNINGS AND PRECAUTIONS

  • Endophthalmitis and Retinal Detachments (5.1).
  • Neovascular AMD (5.2)
  • Increase in Intraocular Pressure (IOP) (5.3).

5.1 Endophthalmitis and Retinal Detachments

Intravitreal injections may be associated with endophthalmitis and retinal detachments [see Adverse Reactions (6.1)]. Proper aseptic injection techniques must always be used when administering IZERVAY in order to minimize the risk of endophthalmitis [see Dosage and Administration (2.4)]. Patients should be instructed to report any symptoms suggestive of endophthalmitis or retinal detachment without delay, to permit prompt and appropriate management [see Patient Counseling Information (17)].

5.2 Neovascular AMD

In clinical trials, use of IZERVAY was associated with increased rates of neovascular (wet) AMD or choroidal neovascularization (7% when administered monthly and 4% in the sham group) by Month 12. Patients receiving IZERVAY should be monitored for signs of neovascular AMD.

5.3 Increase in Intraocular Pressure

Transient increases in intraocular pressure (IOP) have been observed after an intravitreal injection, including with IZERVAY [see Adverse Reactions (6.1)]. Perfusion of the optic nerve head should be monitored following the injection and managed as needed [see Dosage and Administration (2.4)].

6 ADVERSE REACTIONS

The following potentially serious adverse reactions are described elsewhere in the labeling:

The most common adverse reactions were conjunctival hemorrhage (13%), increased IOP (9%), blurred vision (8%) and neovascular age-related macular degeneration (7%) (6.1).

6.1 Clinical Trials Experience

Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical trials of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.

The safety of avacincaptad pegol was evaluated in 733 patients with AMD in two sham-controlled studies (GATHER1 and GATHER2). Of these patients, 292 were treated with intravitreal IZERVAY 2 mg (0.1 mL of 20 mg/mL solution) [see Clinical Studies (14)]. Three hundred thirty-two (332) patients were assigned to sham.

Adverse reactions reported in ≥2% of patients who received treatment with IZERVAY pooled across GATHER1 and GATHER2, are listed below in Table 1.

8 USE IN SPECIFIC POPULATIONS

8.1 Pregnancy

Risk Summary

There are no adequate and well-controlled studies of IZERVAY administration in pregnant women. The use of IZERVAY may be considered following an assessment of the risks and benefits.

Administration of avacincaptad pegol to pregnant rats and rabbits throughout the period of organogenesis resulted in no evidence of adverse effects to the fetus or pregnant female at intravenous (IV) doses 5.1 times and 3.2 times the human exposure (based on AUC) at the maximum recommended human dose (MRHD) of 2 mg once monthly, respectively (see Data).

In the U.S. general population, the estimated background risks of major birth defects and miscarriage in clinically recognized pregnancies is 2-4% and 15%-20%, respectively.

Data

Animal Data

An embryo fetal developmental toxicity study was conducted with pregnant rats. Pregnant rats received daily intravenous (IV) injections of avacincaptad pegol from day 6 to day 17 of gestation at 0.1, 0.4, 1.2 mg/kg/day. No maternal or embryofetal adverse effects were observed at any dose evaluated. An increase in the incidence of a non-adverse skeletal variation, described as short thoracolumbar (ossification site without distal cartilage) supernumerary ribs, was observed at all doses evaluated. The clinical relevance of this finding is unknown. Plasma exposures at the high dose were 5.1 times the MRHD, based on Area Under the Curve (AUC).

An embryo fetal developmental toxicity study was conducted with pregnant rabbits. Pregnant rabbits received daily IV injections of avacincaptad pegol from day 7 to day 19 of gestation at 0.12, 0.4, 1.2 mg/kg/day. No maternal or embryofetal adverse effects were observed at any dose evaluated. Plasma exposure in pregnant rabbits at the highest dose of 1.2 mg/kg/day was 3.2 times the human exposure at the MRHD, based on AUC.

8.2 Lactation

Risk Summary

There is no information regarding the presence of avacincaptad pegol in human milk, the effects of the drug on the breastfed infant, or the effects of avacincaptad pegol on milk production. Many drugs are transferred in human milk with the potential for absorption and adverse reactions in the breastfed child.

The developmental and health benefits of breastfeeding should be considered along with the mother’s clinical need for IZERVAY, and any potential adverse effects on the breastfed infant from IZERVAY.

8.4 Pediatric Use

Safety and effectiveness of IZERVAY in pediatric patients have not been established.

8.5 Geriatric Use

Of the total number of patients who received IZERVAY in the two clinical trials, 90% (263/292) were ≥65 years and 61% (178/292) were ≥75 years of age. No significant differences in efficacy or safety of avacincaptad pegol were seen with increasing age in these studies. No dose adjustment is required in patients 65 years and above.

11 DESCRIPTION

IZERVAY contains avacincaptad pegol sodium, a complement C5 inhibitor. Avacincaptad pegol is a ribonucleic acid (RNA) aptamer, covalently bound to an approximately 43-kiloDalton (kDa) branched polyethylene glycol (PEG) molecule.

The molecular formula of avacincaptad pegol (free acid form) is C395H492N142O262P39F21((CH2)2O)n where n~970 and the molecular weight is approximately 56 kDa. The structure of avacincaptad pegol sodium is presented below.

Futibatinib Str

IZERVAY (avacincaptad pegol intravitreal solution) is a sterile, clear to slightly opalescent, colorless to slightly yellowish solution in a single-dose glass vial for intravitreal administration. Each single-dose vial is designed to deliver 0.1 mL of solution containing 2 mg avacincaptad pegol (oligonucleotide basis), 0.198 mg dibasic sodium phosphate heptahydrate, 0.0256 mg monobasic sodium phosphate monohydrate, and 0.83 mg sodium chloride. IZERVAY is formulated in Water for Injection, with a target pH of 7.3. IZERVAY does not contain an anti-microbial preservative.

12 CLINICAL PHARMACOLOGY

12.1 Mechanism of Action

Avacincaptad pegol is an RNA aptamer, a PEGylated oligonucleotide that binds to and inhibits complement protein C5. By inhibiting C5, avacincaptad pegol may prevent its cleavage to C5a and C5b thus decreasing membrane attack complex (MAC) formation.

12.2 Pharmacodynamics

Increased GA area growth is reflective of loss of photoreceptors and AMD disease progression. Reductions in the rate GA growth were observed from baseline through the first year of treatment across avacincaptad pegol treatment groups in studies GATHER1 and GATHER2.

12.3 Pharmacokinetics

Absorption/Distribution

Following a single dose of avacincaptad pegol, maximum avacincaptad pegol plasma concentrations (Cmax) are estimated to occur approximately 7 days post-dose and mean (CV%) free avacincaptad pegol plasma Cmax is estimated to be 68.4 ng/mL (57.8%) in neovascular AMD (nAMD) patients. The AUC0-28 days following a single 2 mg dose is 1064 day∙ng/mL. Based on a population pharmacokinetic analysis of patients with nAMD, predicted steady state avacincaptad pegol Cmax is 83.9 ng/mL after monthly intravitreal administration of avacincaptad pegol 2 mg.

In humans, avacincaptad pegol plasma concentrations are predicted to be approximately 7,000-fold lower than vitreal concentrations.

Metabolism/Elimination

Metabolism and elimination of avacincaptad pegol has not been fully characterized. Avacincaptad pegol is expected to be catabolized by endonucleases and exonucleases to oligonucleotides of shorter lengths which may be excreted renally, in similar manner to the elimination of endogenous RNA. The estimated apparent systemic half-life of avacincaptad pegol is approximately 12 days.

Specific Populations

Following repeat monthly intravitreal dose administration of 2 mg avacincaptad pegol, no differences in the systemic pharmacokinetics of avacincaptad pegol were observed based on age, gender, and body weight. No special dosage modification is required for any of the populations that have been studied (e.g., age, gender, and body weight). The effect of severe renal impairment or any degree of hepatic impairment on the pharmacokinetics of avacincaptad pegol is unknown. As significant increases in plasma avacincaptad pegol exposures are not expected with intravitreal route of administration, no dosage adjustment is needed based on renal or hepatic impairment status.

13 NONCLINICAL TOXICOLOGY

13.1 Carcinogenesis, Mutagenesis, and Impairment of Fertility

Carcinogenesis

No studies have been conducted on the carcinogenic potential of avacincaptad pegol.

Mutagenesis

Avacincaptad pegol was negative in in vitro (bacterial reverse mutation assay, chromosomal aberration in mammalian cells) and in vivo (mouse bone marrow micronucleus) assays.

Impairment of Fertility

Studies to evaluate the effect of avacincaptad pegol on male or female fertility in animals have not been performed.

14 CLINICAL STUDIES

The safety and efficacy of IZERVAY were demonstrated in two randomized, multi-center, double-masked, sham-controlled, 18- and 12-month studies (GATHER1-NCT02686658 and GATHER2-NCT04435366, respectively) in patients with GA due to AMD. Patient ages ranged from 51 to 97 years with a mean of 77 years. In total, 292 patients were treated with avacincaptad pegol 2 mg, and 332 patients received sham.

In GATHER1 and GATHER2, the mean rate of GA growth (slope) from baseline to Month 12, measured by Fundus Autofluorescence (FAF) was evaluated at 3 time points: baseline, Month 6, and Month 12. Data are available through month 18 for GATHER1 and month 12 for GATHER2. At any time during the GATHER2 study, patients that developed choroidal neovascularization were concomitantly treated with anti-VEGF therapy.

In each study, over a 12-month period, there was a statistically significant reduction of the rate of GA growth (0.10 mm/year; p<0.01 in GATHER1 and 0.05 mm/year; p<0.01 in GATHER2 with square root transformed data) in patients treated with IZERVAY compared to sham. The observed results are shown in Table 2, Figure 1, and Figure 2 below.
