General Dosing Information

For intravitreal injection. VABYSMO must be administered by a qualified physician. Each vial should only be used for the treatment of a single eye.

Neovascular (wet) Age-Related Macular Degeneration (nAMD)

The recommended dose for VABYSMO is 6 mg (0.05 mL of 120 mg/mL solution) administered by intravitreal injection every 4 weeks (approximately every 28 ± 7 days, monthly) for the first 4 doses, followed by optical coherence tomography and visual acuity evaluations 8 and 12 weeks later to inform whether to give a 6 mg dose via intravitreal injection on one of the following three regimens: 1) Weeks 28 and 44; 2) Weeks 24, 36 and 48; or 3) Weeks 20, 28, 36 and 44. Although additional efficacy was not demonstrated in most patients when VABYSMO was dosed every 4 weeks compared to every 8 weeks, some patients may need every 4 week (monthly) dosing after the first 4 doses. Patients should be assessed regularly.

Diabetic Macular Edema (DME)

‚ÄčVABYSMO is recommended to be dosed by following one of these two dose regimens: 1) 6 mg (0.05 mL of 120 mg/mL solution) administered by intravitreal injection every 4 weeks (approximately every 28 days ± 7 days, monthly) for at least 4 doses. If after at least 4 doses, resolution of edema based on the central subfield thickness (CST) of the macula as measured by optical coherence tomography is achieved, then the interval of dosing may be modified by extensions of up to 4 week interval increments or reductions of up to 8 week interval increments based on CST and visual acuity evaluations; or 2) 6 mg dose of VABYSMO can be administered every 4 weeks for the first 6 doses, followed by 6 mg dose via intravitreal injection at intervals of every 8 weeks (2 months). Although additional efficacy was not demonstrated in most patients when VABYSMO was dosed every 4 weeks compared to every 8 weeks, some patients may need every 4 week (monthly) dosing after the first 4 doses. Patients should be assessed regularly.

Preparation for Administration

1.
Before you start:
  • Read all the instructions carefully before using VABYSMO.
  • The VABYSMO kit includes a glass vial and transfer filter needle. The glass vial is for a single dose only. The filter needle is for single use only.
  • VABYSMO should be stored refrigerated at temperatures between 2ºC to 8ºC (36ºF to 46ºF). Do not freeze. Do not shake.
  • Allow VABYSMO to reach room temperature, 20°C to 25°C (68°F to 77°F) before proceeding with the administration. The VABYSMO vial may be kept at room temperature for up to 24 hours. Keep the vial in the original carton to protect from light.
  • VABYSMO should be inspected visually for particulate matter and discoloration prior to administration. VABYSMO is a clear to opalescent and colorless to brownish-yellow liquid solution.
    Do not use if particulates, cloudiness, or discoloration are visible.
    Do not use if the packaging, vial and/or transfer filter needle are expired, damaged, or have been tampered with (see Figure A).
  • Use aseptic technique to carry out the preparation of the intravitreal injection.

2.
Gather the following supplies:
  • One VABYSMO vial (included)
  • One sterile 5-micron blunt transfer filter needle 18-gauge × 1½ inch (included)
  • One sterile 1 mL Luer lock syringe with a 0.05 mL dose mark (not included)
  • One sterile injection needle 30-gauge × ½ inch (not included)
    Note that a 30-gauge injection needle is recommended to avoid increased injection forces that could be experienced with smaller diameter needles.
  • Alcohol swab (not included).
3.
To ensure all liquid settles at the bottom of the vial, place the vial upright on a flat surface (for about 1 minute) after removal from packaging (see Figure B). Gently tap the vial with your finger (see Figure C), as liquid may stick to the top of the vial.

Remove the flip-off cap from the vial (see Figure D) and wipe the vial septum with an alcohol swab (see Figure E).

Aseptically and firmly attach the included 18-gauge × 1½ inch transfer filter needle onto a 1 mL Luer lock syringe (see Figure F).

6.
Using aseptic technique, push the transfer filter needle into the center of the vial septum (see Figure G), push it all the way in, then tilt the vial slightly so that the needle touches the bottom edge of the vial (see Figure H).

7.
Hold the vial slightly inclined and slowly withdraw all the liquid from the vial (see Figure I). Keep the bevel of the transfer filter needle submerged in the liquid, to avoid introduction of air.

8.
Ensure that the plunger rod is drawn sufficiently back when emptying the vial, in order to completely empty the transfer filter needle (see Figure I).
9.
Disconnect the transfer filter needle from the syringe and dispose of it in accordance with local regulations.
Do not use the transfer filter needle for the intravitreal injection.
10.
Aseptically and firmly attach a 30-gauge × ½ inch injection needle onto the Luer lock syringe (see Figure J).

11.
Carefully remove the plastic needle shield from the needle by pulling it straight off.
12.
To check for air bubbles, hold the syringe with the needle pointing up. If there are any air bubbles, gently tap the syringe with your finger until the bubbles rise to the top (see Figure K).

Carefully expel the air from the syringe and needle, and slowly depress the plunger to align the rubber stopper tip to the 0.05 mL dose mark. The syringe is ready for the injection (see Figure L). Ensure that the injection is given immediately after preparation of the dose.

Injection Procedure

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 microbicide 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.

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

Immediately following the intravitreal injection, patients should be monitored for elevation in intraocular pressure. 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., vision loss, eye pain, redness of the eye, photophobia, blurring of vision) without delay [see Patient Counseling Information (17)]. Each syringe should only be used for the treatment of a single eye. If the contralateral eye requires treatment, a new syringe should be used and the sterile field, syringe, gloves, drapes, eyelid speculum, filter, and injection needles should be changed before VABYSMO is administered to the other eye.
