Novartis gains new indication for Lucentis® in EU for vision loss due to Diabetic Macular Edema, a leading cause of blindness
The European Commission has granted Novartis a new indication for Lucentis® (ranibizumab) to treat patients with visual impairment due to diabetic macular edema (DME), a leading cause of blindness in the working-age population in most developed countries.
- (1888PressRelease) January 08, 2011 - Laser therapy, the current standard of care, has provided stabilization of vision in many patients, but generally does not improve vision. Lucentis is the first licensed therapy to significantly improve both vision and vision-related quality of life in patients with visual impairment due to DME.

Pivotal data showed Lucentis provides rapid, superior and sustained vision gains compared to laser therapy, the current standard of care
About half of Lucentis-treated patients gained 10 letters or more in visual acuity in two clinical trials; Such improved vision can restore independence and function

"Similarly to wet age related macular degeneration, diabetic macular edema can cause disabling vision loss. While vision loss as a consequence of diabetes affects only a very small proportion of people with the disease, it is one of the most feared complications," said Don Curran, Chair, AMD Alliance International. "Visual impairment impacts everything from managing social interactions to the ability to work - thus, for most people it means a loss of independence."
The approval of Lucentis was based on data from two Novartis-sponsored clinical trials, RESTORE and RESOLVE, which showed that Lucentis was superior in providing rapid and sustained visual acuity gain versus sham (dummy) therapy or laser therapy, the current standard of care.
"In the clinical trials, Lucentis-treated patients began to recover their vision as early as eight days after the first injection on average, and vision improvement was maintained at one year," said Gabriele E. Lang, Professor, University Eye Hospital, University of Ulm, Germany. "The vision improvement for many of these patients was clinically significant, meaning that they regained the ability to carry out day-to-day activities such as driving."
The RESTORE study showed patients treated with Lucentis alone or with Lucentis plus laser therapy gained an average of 6.8 letters and 6.4 letters, respectively, in visual acuity at 12 months compared to baseline, while laser-treated patients gained an average of 0.9 letters as measured on a standard ETDRS eye chart.
The RESOLVE study showed that Lucentis-treated patients gained an average of 10.3 letters in visual acuity at 12 months compared to baseline while sham-treated patients, some of whom also received laser treatment, lost an average of 1.4 letters.
"Since its first launch in the EU in 2007, Lucentis has become the gold standard treatment of wet AMD and its use has stimulated research into other ocular conditions," said David Epstein, Division Head of Novartis Pharmaceuticals. "Our continued investment in the clinical development of Lucentis means that another group of patients who are at risk of losing their eyesight will have the option of a licensed therapy that could help save their vision."
The pivotal data from RESTORE and RESOLVE studies are further supported by results of an independent US study examining Lucentis for the treatment of DME compared to standard of care. Conducted by the Diabetic Retinopathy Clinical Research Network (DRCR.net), this study showed that at 12 months patients treated with Lucentis plus laser gained an average of nine letters in visual acuity compared to baseline while patients treated with laser therapy alone gained an average of three to four letters. In addition, the study demonstrated superior gains in visual acuity among Lucentis-treated patients up to two years, with a reduced number of Lucentis injections required the second year compared to the first. Specifically, there was a median of only two to three injections required in the second year of treatment compared to a median of eight to nine injections required in the first year.
Diabetic macular edema (DME) is a consequence of diabetic retinopathy, the most common diabetic eye complication. DME is characterized by changes in the blood vessels of the retina, which is the light-sensitive layer at the back of the eye. In patients with DME, leakage from these abnormal blood vessels occurs in the central portion of the retina, called the macula. Because this part of the eye is responsible for sharp central vision, DME can lead to significant visual impairment. Visual impairment due to DME affects approximately 1-3% of patients with diabetes, and DME is a leading cause of blindness in the working-age population in most developed countries.
Lucentis offers an entirely new pharmacological approach to treatment for visual impairment due to DME compared to the current standard of care, which involves the use of laser burns to stop capillary leakage and reduce swelling. Lucentis is an antibody fragment that is injected into the eye and neutralizes vascular endothelial growth factor (VEGF), a protein that is known to increase vascular permeability, resulting in capillary leakage and macular edema in patients with diabetes.
Lucentis was generally well tolerated in DME clinical studies, either when given as monotherapy or when combined with laser treatment. Its safety profile was consistent with the well established profile in patients with wet age-related macular degeneration (wet AMD). There was an incidence of arterial thromboembolic events (
