Dose Adjustments

Although Not as Effective, the Following Dosing Regimens May Be Used in Patients with Neovascular (Wet) AMD:

• Administer 3 monthly doses followed by less frequent dosing with regular assessment. In the 9 months after 3 initial monthly doses, less frequent dosing with 4 to 5 doses on average is expected to maintain visual acuity while monthly dosing may be expected to result in an additional average 1 to 2 letter gain.

• Administer 1 dose every 3 months after 4 monthly doses with regular assessment. Compared with continued monthly dosing, dosing every 3 months over the next 9 months will lead to an approximate 5-letter (1-line) loss of visual acuity benefit on average.

Precautions

Safety and efficacy have not been established in patients younger than 18 years.
