Eligibility criteria:

        Inclusion Criteria:

        Subjects eligible for enrolment in the study must meet all of the following criteria:

          -  Consent: Subject understands the procedures, agrees to participate in the study
             (including participation in the CFH Y402H pharmacogenetic research), and has signed
             and dated the informed consent form prior to the initiation of any study-related
             activities. If the subject is unable to read the consent form due to visual impairment
             then the consent must be read to the subject verbatim by the person administering the
             consent, a family member, or legally acceptable representative. (Note: Consent by
             legally acceptable representative is allowed where this is in accordance with local
             laws, regulations, and ethics committee policy.)

          -  Age-related macular degeneration: For each subject enrolled in the study, only one eye
             (study eye) will be treated, and eligibility criteria apply to the study eye. All of
             the following characteristics are required and must be confirmed by the central
             reading center:

          -  CNV caused by AMD that extends under the geometric center of the foveal avascular zone

          -  Center subfield thickness (inclusive of subretinal fluid) > 320 microns on OCT
             [SPECTRALIS® (Heidelberg)]

          -  Total lesion area ≤12 disc areas on fluorescein angiography, where the lesion complex
             includes CNV, blood, blocked florescence not from blood, and serous detachment of the
             retinal pigment epithelium

          -  CNV comprises < 50% of lesion area

          -  classic CNV comprises < 50% of the lesion area

          -  fibrosis comprises ≤ 25% of lesion area

          -  if no evidence of classic CNV, then presumed to have recent disease progression based
             on deterioration (≥ 5 letter decrease in vision or evidence of growth of a CNV lesion
             on fluorescein angiography ) within the last 3 months or evidence of hemorrhage from
             CNV

          -  Visual acuity: Best-corrected visual acuity score by electronic ETDRS in the study eye
             of between 25 and 73 letters (approximately equivalent to Snellen VA of 20/320 to
             20/32) at screening

          -  Gender and age: Subject is a male or female adult 50 years of age or older.

          -  Non-childbearing potential: Female subject is of non-childbearing potential defined as
             being physiologically incapable of becoming pregnant. This includes any female who is
             post-menopausal (12 months of spontaneous amenorrhea) or who is surgically
             post-menopausal (via documented hysterectomy or bilateral tubal ligation). In
             questionable cases of postmenopausal status, a blood sample with simultaneous follicle
             stimulating hormone (FSH) >40 MIU/mL and estradiol <40 pg/mL (<140 pmol/L) [or
             equivalent values based on local laboratory criteria] is confirmatory. Refer to the
             SPM for more information.

          -  Study Compliance: Subject is able and willing to comply with the study requirements
             and is able and willing to attend all scheduled visits.

          -  Liver function tests: Subject has liver chemistry values that are within normal limits
             or clinically insignificant as evidenced by serum aspartate aminotransferase (AST) and
             alanine aminotransferase (ALT) <2xULN; alkaline phosphatase and bilirubin <1.5xULN
             (isolated bilirubin >1.5xULN is acceptable, if bilirubin is fractionated and direct
             bilirubin is < 35%).

          -  QT interval: Subject has a QTcF value < 450 msec, or < 480 msec for subjects with
             Bundle Branch Block. [Note: subjects with paced rhythms may be considered pending
             discussion with the medical monitor.]
