But now new anti-VEGF eye injections can be very effective in reducing the leakage (oedema) and keeping good sight, and nearly all patients will keep good sight.
At worse levels of initial visual acuity, aflibercept is more effective at improving vision NEJM 16.
Lucentis (Avastin would be equally effective and 10% the cost) has been approved by NICE if oedema >400Aµ: monthly injections until oedema stable, and then continuing monitoring offering injections if oedema increases again.
Each one anti-VEGF injections will have temporary effect, and monthly treatment may be needed, especially for a while. Anti-VEGF injections we are likely to get much better results than we did previously, and none smokers detected early (unless control is very poor indeed) should be expected to keep good vision. On the other hand, when lots of anti-VEGF treatment has been given and the haemorrhages etc disappear, the condition may reactivate unless the diabetic control has improved a lot.
Diabetes mellitus is a disease of elevated blood sugar damaging the blood vessels all over the body including the eyes. The earliest form of diabetic retinopathy is found when examining the inside of the eye, specifically the retina. If damage to the blood vessels worsens, the oxygen supply to the eye decreases, called ischemia. The goal of any treatment, laser, steroid injections or anti-VEGF injections is to reduce the swelling.
Usually, a fluorescein angiogram is performed to demonstrate where the normal retinal blood vessels are leaking.
Treatment can involve anywhere from a few to dozens of burns…all depending upon the number leaks. Laser treatment to the center of the macula could lead to a permanent blind spot in the vision and, therefore, is not always the best treatment for every patient.
After 4-6 months, I can usually tell if the laser treatment is effective or needs to be augmented (ie. There are a variety of treatments for diabetic macular edema.   Laser treatment is still the standard of care for treating this common condition seen with diabetic retinopathy.
Diabetic retinopathy can not be cured, but we are often successful maintaining status quo…provided regular checkups occur. After complete dilated exam, I was happy to report to him that he needed cataract surgery and, most importantly, there were no signs of diabetic macular edema nor active proliferative disease. I noted his weight was stable, hinting AB is very disciplined and, unlike me, has been able to control his weight over the years. My point is that the disease is not certain to cause blindness or even severe loss of vision and I wanted to share a good story of seeing well despite chronic disease…and a trusting friendship. Iluvien advances in the regulatory process for use in the treatment of diabetic macular edema in Europe. Alimera Sciences’s efforts for FDA approval of Iluvien in the United States were stymied in 2011 citing concerns over safety and requesting additional clinical trials. One of the more common symptoms of diabetic retinopathy is loss of vision due to swelling in the retina, more specifically, in the macula.  This is called Diabetic Macular Edema (DME). The macula gives us central vision.   When fluid accumulates within the macula, the vision worsens.
Alternative include intravitreal injections of steroid or anti-VEGF (such as Avastin or Lucentis).
Iluvien, similar to its cousin Ozurdex (already FDA approved, but for the use of retinal vascular occlusions), is an injectable sustained release device that will release steroid for up to 36 months!  Iluvien has hopes of being the first sustained release delivery system for the treatment of diabetic retinopathy.
Iluvien represents an emerging treatment for diabetic macular edema, a disease that clearly needs to be treated in a variety of ways.  Ophthalmologists are limited in our ability to treat these patients as not all patients with this sight threatening complication are candidates for laser treatment. While we may not see Iluvien available here in the US, perhaps its approval and use in another country will be enough for a company such as Alimera Sciences to sustain them as a business and allow them to continue their research and development of newer technologies.
Iluvien was to be indicated for the treatment of diabetic macular edema, a very common complication of patients with diabetic retinopathy.  Typically, patients receive laser treatment as a first line treatment, but alternative treatments have been long needed as laser can not be performed in everyone.
The sustained release device is injected into the eye and will release a steroid, fluocinolone, for up to 36 months.  Shorter acting steroid injections have demonstrated favorable results and it was anticipated that a sustained release system might offer a realistic benefit of better drug levels and little need for reinjection.
Moreover, Iluvien would have validated sustained release drug delivery systems.  Ozurdex was first and Iluvien would have been the second delivery system designed for injection into the vitreous.
A second approved product, regardless of indication, would have been a significant endorsement for injectable sustained release systems.  Sustained release devices for macular degeneration (sustained release drug delivery of anti-VEGF), post-operative medications and glaucoma seem logical.
I prefer treating and controlling the macular swelling first, before treating the neovascular disease (PDR). When possible, I’ll treat the macular edema with focal and wait several weeks, or months, to treat with scatter laser.
Avastin, however, has improved my ability to treat those patients with both macular and proliferative disease. Such safety and efficacy data were presented recently to the public at a large ophthalmic meeting in FL last month.  The company has also submitted this data to the FDA (Food and Drug Administration). In short, the company performed two large clinical trials, the so-called FAME study showed that about 33% of patients  receiving the implant noted an improvement in vision.  Of significance is that this improvement, according to the company, was present after 3 years. Last year, the FDA also asked for a review of the manufacturing process of Iluvien, but I am not aware of any specific elements that were made public.  These, too, have been addressed.
About a year ago, Alimera Sciences submitted the new drug application (NDA) for it’s proprietary intraocular drug delivery system for the treatment of diabetic macular edema (DME).
Last December, the FDA failed to approve the NDA, but, instead requested more data about the efficacy (how well a drug works) of Iluvien.  This was provided this Spring.
If you remember, Ozurdex, the first sustained release intraocular drug delivery system was approved for treatment of retinal edema caused by retinal vascular diseases. It may be that a second such device may be shortly approved for the treatment of diabetic retinopathy.  While this further endorsed the sustained release technology, it will be a breakthrough that allows significantly more people to be helped that presently have few options. Treating diabetic retinopathy with both laser and anti-VEGF injections may be the best way to treat patients with diabetic macular edema. The results of a large, multicenter, randomized clinical trial compared several permutations of laser and the anti-VEGF drug, Lucentis.


To date, standard treatment, or the standard of care, includes treating the retina with laser photocoagulation to retard the loss of vision.
This new study not only validates the use of anti-VEGF medications, but also hints that anti-VEGF may be superior to steroids.
Most importantly, however, the study describes a treatment regimen that leads to improvement, stabilization and reduction in the number of treatments! As with it’s predecessors, Macugen and Lucentis, the company must prove to the FDA that the drug is effective and safe. Regeneron has also started Phase III clinical trials for VEGF-Trap for the treatment of diabetic macular edema.
Diabetic macular edema is the leading cause of decreased vision in patients with diabetes under the age of 50. On the other hand, using VEGF-Trap for the treatment of diabetic retinopathy will be the first drug to gain FDA approval.
Diabetic macular edema (DME) is swelling in the retina caused by diabetic retinopathy.  More specifically, the swelling is located in the macula, the functional center of the retina. Diabetes can be considered a disease of blood vessels, caused in some way by high sugar levels.  For reasons that are not completely known, the blood vessels in the retina start to leak, both blood and the fluid component of blood.
Regardless, fear not, the treatment for the disease is quite successful in preventing further vision loss. The Food and Drug administration fails to approve Iluvien for the treatment of diabetic retinopathy and cites the need for more safety information in addition to concerns about the safety of the manufacturing process of Iluvien.   Alimera Sciences had hoped to gain approval by the end of December 2010, instead, it was told by the FDA that more information was needed.
There were also concerns regarding the manufacturing, packaging and sterilization of Iluvien, though no specifics were noted.
Iluvien may be the second drug approved that is based on technology to offer sustained drug delivery into the eye.  Ozurdex, a similar product, has been in use since the summer of 2009 and is used for retinal vein occlusions. Had the product been rejected, or requests for additional clinical trials, this would have been a clearer signal of failure. In the end, though disappointing, the company hopes to have a marketable product by the end of 2011. VEGF - Vascular Endothelial Growth Factor is a substance naturally liberated by the cells of the body.
In wet ARMD, liberation of VEGF causes growth of new blood vessels behind the retina, in subretinal space.
In diabetic retinopathy, the basic disease process results in blockages of the small vessels, reducing the blood supply to areas of the retina. In retinal vein occlusions too, liberation of VEGF from ischemic retina results in retinal neovascularisation and macular edema.
Ranibizumab (Lucentis) - It is an antibody binding fragment, which binds and neutralizes all active forms of the VEGF molecule. Bevacizumab (Avastin) - It is an antibody to VEGF which binds to and neutralize all the active forms of the VEGF molecule.
Pegabtanib (Macugen) - It is a molecule that acts only against one form of VEGF, and thus is not that effective. The anti VEGF injections do not cure the primary disease affecting the retina, but they help to treat the effects of the disease on the retina. In Vein occlusions, the main disease is due to occurrence of thrombus (clot) in the retinal vein. In diabetic retinopathy, the injections do not cure the diabetes, nor do they prevent the retina from getting affected, if the diabetes is uncontrolled. Anti VEGF injections are often used as combination treatment, to reduce the new vessels on retina before doing surgery (vitrectomy). The anti VEGF drugs have a short lived effect, and need to be repeated at monthly or 6 weekly intervals.
The potential complications include those from giving an intravitreal injection, such as infection or increased eye pressure. They also carry a risk of stroke in the elderly, especially if they have had a recent stroke, though this has not been proved conclusively. VEGF Trap Eye (aflibercept) is the newest anti VEGF drug, which is currently under research. Iluvien is now available in the United States!  Finally receiving FDA approval in late 2014, the injectable sustained release intravitreal implant  is on the market. Alimera Sciences states that Iluvien (sustained release of fluocinolone) will release its drug for up to 3 years. Diabetic macular edema is the most common vision threatening complication of diabetic retinopathy.  In essence, normal blood vessels of the retina become leaky due to the diabetic retinopathy. Fluid accumulation in or near the center of the macula is called diabetic macular edema (DME).  This is also known as clinically significant macular edema (CSME) if you are a doctor.
By injecting directly into the eye, as with all intravitreal injections, only small amounts of drug are needed to treat the retina. The steroid will chemically stop the retinal vessels, affected by the diabetic retinopathy, from leaking. Constant treatment for 36 months may have huge practical advantages; namely fewer offices visits and less testing. Iluvien continues to make progress outside the US for treatment of macular edema due to diabetic retinopathy. Iluvien was just approved for use in Austria several weeks ago.  This marks the first sustained release pharmaceutical in that country for the treatment of DME (diabetic macular edema).
More recently, the United Kingdom allowed marketing authorization for Iluvien, too.  This is the second EU (European Union) country to accept the drug. Iluvien is not approved for use in the United States.  Most recently, the FDA was not satisfied with the safety data presented by Alimera Sciences, Inc. Treatment of macular edema from diabetes is difficult and can be frustrating.  Intraocular injections have been a great alternative to the gold standard of laser treatment.
Laser treatment for diabetic macular edema is not appropriate for all patients and alternative treatments are needed.


An earlier post covered Iluvien’s safety and efficacy in phase 2 trials for the treatment of diabetic macular edema. New Drug Application (NDA) is usually the last step for a company, or sponsor, to be allowed to market and sell the drug.  Alimera expects NDA submission later in 2010 after completion and analysis of the phase 3 data.
Ok, maybe a bit dramatic, but another article was recently published stating that intravitreal injections were used with success to treat diabetic macular edema.   These effects lasted at least 5 years, the duration of the study. The results were that vision improved and swelling decreased in the first group.  In the second group, the vision improved and swelling decreased, but only after receiving the steroids.
Earlier this week, I wrote about a device, Iluvien ™, that will release steroid into the eye.  This drug delivery system is manufactured by Alimera Sciences. Alimera Sciences has announced that early data is showing that the drug system is safe and effective in humans.  The results are preliminary, but promising.
Phase 2 clinical drug trials are designed to show safety of a drug at different doses.  So far, after 18 of 36 months have been completed, both high and low doses of Iluvien™ appear to be safe and free from systemic side effects. If you recall, Iluvien ™ releases fluocinalone, a steroid for the treatment of diabetic retinopathy.  It is also exciting to find that both doses of Iluvien ™ may be effective at reducing macular edema and improving vision. Lastly, the advantages of sustained released systems can not be understated.  While it may sound a little aggressive to be injecting medicine directly into the eye, it is proving to be very effective in treating many eye diseases such as macular degeneration.
This is for short term use only, and is very useful for macular oedema after cataract surgery. Many patients with type 1 diabetes may benefit from an insulin pump, and these may be necessary to achieve the best results.
Such patients need to be monitored regularly, and in the UK this will usually be in the diabetic retinopathy screening program with regular photographs.
Supplemental tests such as OCT, Fluorescein angiography and ultrasound will help determine if treatment such as laser or injections of anti-VEGF drugs will heal the eye. It is important for growth of normal blood vessels, during wound healing, and to form new vessels to restore the oxygen supply, in areas where the blood supply or oxygen supply is less. These new vessels can leak fluid or cause bleeding at the macula, resulting in the symptoms of reduced or distorted vision in Neovascular ARMD. This causes liberation of VEGF, which stimulates new vessels to grow on the surface of the retina. It has been approved for use in metastatic colorectal cancer, and is not yet FDA approved for use in the eye.
Now the uses have been expanded to include diabetic macular edema, macular edema associated with retinal vein occlusions, vitreous hemorrhage, retinopathy of prematurity, and Choroidal neovascularisation due to other causes such as high myopia, choroiditis, angiod streaks or idiopathic. The anti VEGF injections do not cure the aging process, but they help control the leakage and bleeding from the new vessels, hence reducing the swelling in retina and the symptoms of distorted vision. The injection does not remove the clot, but it helps to reduce the macular edema (swelling) occurring due to the blockage by the clot, and thus improves vision. The injections however help to reduce the macular edema (swelling) that occurs due to leakage from the new vessels. It binds VEGF more effectively, and also binds more varieties of VEGF, thus it may have a longer duration of action than currently available treatments.
Avastin, Lucentis, Eylea), intravitreal steroids (Kenalog) or sustained release intravitreal implants (Ozurdex, Iluvien).
There are 3 phases of clinical trials (sometimes an additional phase 4 is required) and the NDA (New Drug Application). Food and Drug Administration) testing seems to be going as planned for the Alimera Sciences.  The Iluvien drug delivery system moves another step closer to approval (after phase 2, a phase 3 clinical trial will need to be competed). At present, NICE guidelines only recommend anti-VEGF injections if there is more than 400Aµ macular oedema, although some hospitals are able to offer Avastin treatment which is very effective.
The retinopathy is nearly stable, and unless the diabetic control is poor, is unlikely to change. Quitting smoking is extremely important as inhaling cigarette smoke leads to less oxygen in the body. As well fluid leaks from the damaged blood vessels and causes edema or swelling in the layers of the retina. In many retinal diseases such as Wet Age Related Macular Degeneration (ARMD), Diabetic Retinopathy, Retinopathy of Prematurity and Retinal Vein Occlusions, liberation of VEGF results in growth of new blood vessels and causes these vessels to leak, resulting in accumulation of fluid (swelling) and haemorrhage (blood) in the eye.
These new vessels can bleed, resulting in vitreous hemorrhage, or cause proliferation of fibrovascular tissue and lead to tractional retinal detachments. Hence it is absolutely necessary to keep the main disease under control (such as control of diabetes) even if the patient is receiving anti VEGF injections, as these do not cure the diabetes. If you are a type 1 patient and cannot achieve good control, you need to checked for other conditions such as coeliac disease (anti-TTG antibodies), addisons, and thyroid. They will reduce the proliferation without causing retinal scarring or epiretinal membrane formation.
If this occurs in the center of the macula, vision can become blurred and distorted, sometimes permanently. Eventually, I operated to remove a vitreous hemorrhage resulting from his proliferative diabetic retinopathy. Leakage of fluid from these vessels at the macula can result in diabetic macular edema (swelling).
Also, as the effect of the injections is short lived, it may be necessary to give repeated injections at 4-6 weeks interval, to have a more long lasting effect. However currently it is not yet available for clinical use, the FDA is considering it for treatment of Neovascular AMD.
