| E.1.2 | Classification code | 10015902 |
| E.1.2 | Term | Exudative senile macular degeneration of retina |

| E.2 Objective of the trial |
| E.2.1 | Main objective of the trial |
| To estimate the relative effectiveness of standard versus low dose Avastin® (bevacizumab) for intravitreal injection on visual outcome in patients with nAMD. |
|
| E.2.2 | Secondary objectives of the trial |
| 1. To estimate the effectiveness of more frequent vs. less frequent VEGF inhibition in improving or maintaining visual function, with stringent criteria for restarting treatment to prevent visual acuity loss in patients receiving less frequent treatment. 2. To describe the adverse effects of different Avastin® doses and review regimens. |
|
| E.2.3 | Trial contains a sub-study | No |
| E.3 | Principal inclusion criteria |
| •Any patient newly referred for the treatment of nAMD or reactivation of nAMD, i.e. disease stable with no treatment for nAMD to either eye for the previous 6 months, who is considered eligible for anti-VEGF treatment in the NHS. |
|
| E.4 | Principal exclusion criteria |
| • Pregnant and or lactating women • Women with child bearing potential (i.e. not sterilised or not post menopausal) who are unwilling to use contraception • Men with a spouse or partner with child bearing potential unless the participant has agreed to use condoms • Patients with known hypersensitivity to recombinant human or humanised antibodies |
|
| E.5 End points |
| E.5.1 | Primary end point(s) |
| The primary endpoint is defined by the time-to-an-event, i.e. vision deterioration as measured with distance visual acuity assessments using the logMAR scale. This allows any period of observation in the trial, however short, to contribute to answering the trial objectives. With such an outcome, there is no need to define a primary endpoint in time. |
|
| E.5.2 | Secondary end point(s) |
| (i)Frequencies of adverse effects of treatment (ii)Corrected distance visual acuity (VAlogMAR), measured as the number of letters read on a standard ETDRS chart (testing initially at 3 or 4 metres depending on the facilities at sites and then at 1 metre if <20 letters are read at 3 or 4 metres; total letters read are scored ‘as if’ viewing at 1 metre). |
|
| E.5.2.1 | Timepoint(s) of evaluation of this end point |
| Secondary endpoints will be analysed 18 months after the start of recruitment, 30 months after the start of recruitment and then annually, unless otherwise stated, using data available at the time. |

Definition of the end of the trial and justification where it is not the last
visit of the last subject undergoing the trial
|
| The trial will end for all patients once the target number of events has been reached (304 eyes in separate patients withdrawn due to vision deterioration despite ongoing treatment). This is justified as the primary outcome for this trial is "time-to-event" and once 304 events have been recorded the primary data collection will have been completed. |
