Lucentis Efficacy in DME
The approval of Lucentis in DME was based on Genentech’s Phase III trials, RIDE and RISE, two identically-designed, parallel, double-masked, three-year clinical trials, which were sham-treatment controlled for 24 months. A total of 759 patients were randomized into three groups to receive monthly treatment with 0.3 mg Lucentis (n=250), 0.5 mg Lucentis (n=252) or sham injection (control group, n=257). Primary outcomes were evaluated at 24 months and have been published in Ophthalmology. 4
In the studies, treatment with Lucentis demonstrated improved clinical outcomes including substantial visual gain for many DME patients. Results showed patients who received 0.3 mg Lucentis experienced significant, early (Day 7) and sustained (24 months) improvements in vision:
- More patients who received Lucentis were able to read at least three additional lines (15 letters) on the eye chart at 24 months: RIDE: 34 percent in the 0.3 mg group versus 12 percent in the control group; RISE: 45 percent, 0.3 mg versus 18 percent, control (primary endpoint)
- Patients who received Lucentis had average vision gains exceeding two lines (10 letters) on the eye chart at 24 months: RIDE: 10.9 letters, 0.3 mg versus 2.3 letters, control; RISE: 12.5 letters, 0.3 mg versus 2.6 letters, control
- Significant gains in average vision were observed 7 days after the first treatment
- Patients who received Lucentis were significantly more likely to maintain their vision (lose < 15 letters on the eye chart) at 24 months: RIDE: 98 percent, 0.3 mg versus 92 percent, control; RISE: 98 percent, 0.3 mg versus 90 percent, control
For all time points comparing 0.3 mg Lucentis to control through Month 24 p < 0.01.Vision improvements observed in patients treated with Lucentis at 24 months were maintained with continued treatment through 36 months.
