We’re for Sustained Disease Control of DME
DME
EYLEA 8mg is indicated in adults for the treatment of visual impairment due to diabetic macular oedema (DME).
PHOTON (DME): a robust randomised trial of EYLEA 8mg
vs. EYLEA 2mg
Lasting vision gains maintained with extended intervals
- ~9/10 patients randomised to the q16 arm had a last assigned treatment interval of ≥q16 through Week 96
- ½ of DME patients had a last assigned treatment interval of q20 or more
Fluid control maintained through Week 96
We’re for those who want to maximise vision gains and minimise burden
Lasting BCVA gains from baseline were maintained from Week 48 to Week 96, with as few as 8 injections over 2 years
- In Year 2, interval extensions were allowed for patients on 8q12 or 8q16
LS mean change in BCVA from baseline to Week 96

We’re for those who want to confidently extend intervals for more patients
An unprecedented ~9 out of 10 patients randomised to the q16 arm achieved a last assigned dosing interval of ≥q16 at Week 96
~1 in 2 DME patients achieved intervals of ≥q20 while maintaining vision gains, within 2 years in PHOTON

- g1-sided test for non-inferiority at 4-letter margin (based on adjusted means derived using MMRM analysis). LS mean change from baseline at Week 48 was +8.1 letters for 8q12, +7.2 letters for 8q16 and +8.7 letters for 2q8. Differences in LS means vs. 2q8 were -0.6 (95% CI: -2.3, 1.1; p<0.0001) for 8q12 and -1.4 (95% CI: -3.3, 0.4; p=0.0031) for 8q16.2²
