Lucentis Efficacy in DMEThe 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
Lucentis Safety in DMEThe benefit/risk profile of Lucentis was favorable in patients with DME through 36 months in the clinical trials. Pooled safety analysis of RIDE and RISE at 24 months showed:
- The ocular safety of Lucentis in patients with DME was generally consistent with that established in patients with wet AMD and RVO (through 36 months).
- The most common ocular events occurring at a higher rate in patients receiving 0.3 mg Lucentis compared to the control groups included conjunctival hemorrhage (bleeding under the lining of the eye): 47 percent, 0.3 mg versus 32 percent, control; eye pain: 17 percent, 0.3 mg versus 13 percent, control; foreign body sensation in eyes: 10 percent, 0.3 mg versus 5 percent, control; vitreous floaters: 10 percent, 0.3 mg versus 4 percent, control; and increased eye pressure: 18 percent, 0.3 mg versus 7 percent, control.
- Rates of these events were similar among DME patients receiving 0.3 mg Lucentis and the control groups at 24 months at 5.6 percent, 0.3 mg versus 5.2 percent, control. The rate of ATE events at 36 months was 10.8 percent for patients in the 0.3 mg treatment group (control period ended at 24 months).
- The rate of stroke in DME patients at 24 months was 1.2 percent, 0.3 mg versus 1.6 percent, control. The rate of stroke at 36 months was 2.0 percent for patients in the 0.3 mg treatment group.
About DMEDME is swelling of the macula, the central part of the retina responsible for sharp, central vision. 5 DME begins with diabetes, which can cause damage to blood vessels in the eye over time. When this happens, a patient is said to have diabetic retinopathy, the most common diabetic eye disease. The damaged blood vessels can leak blood and fluid, causing swelling and blurred vision, severe vision loss and sometimes blindness. 5 Nearly 26 million Americans have diabetes, which has become the leading cause of new cases of blindness in adults aged 20-74. 1 Among Americans aged 40 years and older, more than 4.2 million have diabetic retinopathy, according to the 2005-2008 National Health and Nutrition Examination Survey (NHANES). 6 A subsequent analysis estimates that 560,500 have DME. 2 It has also been estimated that up to 10 percent of people with diabetes will get DME during their lifetime. 7 About Lucentis Lucentis is a prescription medicine for the treatment of patients with wet AMD, macular edema following RVO and DME. Lucentis is a recombinant humanized monoclonal antibody fragment (lacking an Fc region). Lucentis is the first VEGF inhibitor specifically designed for use in the eye to bind to and inhibit VEGF-A, a protein that is believed to play a critical role in the formation of new blood vessels (angiogenesis) and the hyperpermeability (leakiness) of the vessels. In wet AMD, these new blood vessels grow under the retina and leak blood and fluid, causing rapid damage to the macula. Lucentis administered monthly in wet AMD clinical trials demonstrated an improvement in vision of three lines or more on the study eye chart in up to 41 percent of patients at two years. Nearly all patients (90 percent) treated monthly with Lucentis in those trials maintained (defined as losing < 15 letters) vision.
In RVO, angiogenesis and hyperpermeability can lead to macular edema, the swelling and thickening of the macula. Lucentis administered at 0.5 mg monthly in RVO clinical trials demonstrated the following average vision gains for patients at six months: patients with branch-RVO experienced an average gain of 18.3 letters on the study eye chart (compared to 7.3 letters for the control group) and patients with central-RVO experienced an average gain of 14.9 letters on the study eye chart (compared to 0.8 letters for the control group).Lucentis has been rigorously studied in multiple retinal diseases in 27 clinical trials involving more than 10,500 patients worldwide. Outside the U.S., Lucentis has received regulatory approval for treatment of visual impairment due to DME in more than 75 countries, for treatment of wet AMD in more than 100 countries and for treatment of RVO in more than 70 countries. Lucentis was discovered by Genentech and is being developed by Genentech and Novartis for diseases or disorders of the eye. Genentech retains commercial rights in the U.S. and Novartis has exclusive commercial rights for the rest of the world. Lucentis in DME Indication Statement Lucentis 0.3 mg (0.05 mL of 6 mg/mL Lucentis solution) is recommended to be administered by intravitreal injection once a month (approximately 28 days) for treatment of diabetic macular edema (DME). Lucentis Safety Lucentis is a prescription medicine given by injection into the eye, and it has side effects. Lucentis is not for everyone. You should not use Lucentis if you have an infection in or around the eye or are allergic to Lucentis or any of its ingredients. Some Lucentis patients have serious side effects related to the injection. These include serious infections inside the eye, detached retinas, and cataracts. Other uncommon serious side effects include inflammation inside the eye and increased eye pressure. These side effects can make your vision worse. Some patients have had increased eye pressure within one hour of an injection. Your eye doctor should check your eye pressure and eye health during the week after your Lucentis injection.
Uncommonly, Lucentis patients have had serious, sometimes fatal, problems related to blood clots, such as heart attacks or strokes.If your eye becomes red, sensitive to light, or painful, or if you have a change in vision, call or visit your eye doctor right away. The most common eye-related side effects are increased redness in the white of the eye, eye pain, small specks in vision, and increased eye pressure. The most common non-eye-related side effects are nose and throat infections, headache, lung/airway infections, and nausea. Lucentis is for prescription use only.
