Ranibizumab, sold under the brand name Lucentis among others, is a monoclonal antibody fragment (Fab) created from the same parent mouse antibody as bevacizumab. It is an anti-angiogenic [16] that is approved to treat the "wet" type of age-related macular degeneration (AMD, also ARMD), diabetic retinopathy, and macular edema due to branch retinal vein occlusion or central retinal vein occlusion.

Contents

Ranibizumab was developed by Genentech and marketed by them in the United States, and elsewhere by Novartis, [17] under the brand name Lucentis. [14] [17] [18] Ranibizumab (Lucentis) was approved for medical use in the United States in June 2006, [18] [14] and in the European Union in January 2007.

Medical uses

In the United States, ranibizumab is indicated for the treatment of neovascular (wet) age-related macular degeneration, macular edema following retinal vein occlusion, diabetic macular edema, diabetic retinopathy, and myopic choroidal neovascularization. [14] [19]

In the European Union, ranibizumab is indicated for the treatment of neovascular (wet) age-related macular degeneration, visual impairment due to diabetic macular edema, proliferative diabetic retinopathy, visual impairment due to macular edema secondary to retinal vein occlusion, and visual impairment due to choroidal neovascularisation. [15] [2] [4]

It is used for age-related wet macular degeneration. [20] Its effectiveness is similar to that of bevacizumab [21] [22] and aflibercept. [23] A 2023 systematic review update found that while ranibizumab and bevacizumab provide similar functional outcomes in diabetic macular edema, there is low-certainty evidence suggesting that ranibizumab is more effective in reducing central retinal thickness than bevacizumab. [24]

Susvimo is a reformulation of ranibizumab suitable for injection via ocular implant. [25] Susvimo was approved for medical use in the United States in October 2021. [7] [26]

Side effects

A 2014 Cochrane review did not find a difference between bevacizumab and ranibizumab in deaths or total severe side effects when used for macular degeneration. [27] There, however, was not a lot of evidence, and thus this conclusion is not that certain. [27]

Ranibizumab does appear to result in a lower risk of stomach and intestinal problems. [27] It is also associated with a low rate of eye related side effects. [28]

Serious adverse events related to the injection procedure occurred with an incidence rate of less than 1% and included endophthalmitis, retinal detachment, and traumatic cataracts. Other serious ocular adverse events observed among ranibizumab-treated patients (incidence rate < 1%) included intraocular inflammation and blindness. [29]

Interactions

No significant interactions are known. [30]

Pharmacology

Ranibizumab is a monoclonal antibody that inhibits angiogenesis by inhibiting vascular endothelial growth factor A, a mechanism similar to that of bevacizumab. [31]

Society and culture

Biosimilars

Byooviz was approved for medical use in the European Union in August 2021. [2] [32]

Ranibizumab-nuna (Byooviz) was approved for medical use in the United States in September 2021. [1] [19]

In India, Lupin Limited received marketing approval for its biosimilar of Ranibizumab. [33]

In June 2022, the Committee for Medicinal Products for Human Use (CHMP) of the European Medicines Agency (EMA) adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Ranivisio, intended for the treatment of neovascular (wet) age-related macular degeneration, visual impairment due to macular edema or choroidal neovascularization, and proliferative diabetic retinopathy. [34] The applicant for this medicinal product is Midas Pharma GmbH. [34] Ranivisio was approved for medical use in the European Union in August 2022. [4] [35]

Ranibizumab-eqrn (Cimerli) was approved for medical use in the United States in August 2022. [3] [36]

In September 2022, the CHMP adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Ximluci, intended for the treatment of neovascular (wet) age-related macular degeneration, visual impairment due to diabetic macular edema, proliferative diabetic retinopathy, visual impairment due to macular edema secondary to retinal vein occlusion (branch RVO or central RVO), and visual impairment due to choroidal neovascularization. [37] The applicant for this medicinal product is STADA Arzneimittel AG. [37] Ximluci was approved for medical use in the European Union in November 2022. [8] [38]

In November 2023, the CHMP adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Rimmyrah, intended for the treatment of neovascular (wet) age-related macular degeneration, visual impairment due to diabetic macular edema, proliferative diabetic retinopathy, visual impairment due to macular edema secondary to retinal vein occlusion (branch RVO or central RVO), and visual impairment due to choroidal neovascularization. [39] The applicant for this medicinal product is QILU PHARMA SPAIN S.L. [39] Rimmyrah is a biosimilar medicinal product that is highly similar to the reference product Lucentis (ranibizumab), which was authorized in the EU in January 2007. [39] Rimmyrah was approved for medical use in the European Union in January 2024. [6] [40]

In January 2024, Sandoz signed an agreement to acquire ranibizumab-eqrn, the biosimilar version of ranibizumab branded as Cimerli from Coherus BioSciences, Inc. for an upfront cash purchase payment of US$170 million. [41] [42] [43]

In July 2024, the CHMP adopted a positive opinion, recommending the granting of a marketing authorization for the medicinal product Ranibizumab Midas, intended for the treatment of neovascular (wet) age-related macular degeneration, visual impairment due to diabetic macular edema, proliferative diabetic retinopathy, visual impairment due to macular edema secondary to retinal vein occlusion and visual impairment due to choroidal neovascularization. [44] The applicant for this medicinal product is Midas Pharma GmbH. [44] Ranibizumab Midas is a biosimilar medicinal product and is a duplicate of Ranivisio. [44]

Economics

Its effectiveness is similar to that of bevacizumab. [21] [45] Its rates of side effects also appear similar. [27] However, ranibizumab typically costs $2,000 a dose, while the equivalent dose of bevacizumab typically costs $50. [46] [47] [48] [49]

Genentech offered secret rebates to about 300 ophthalmologists in an apparent inducement to get them to use more ranibizumab rather than the less expensive bevacizumab. In 2008, bevacizumab cost Medicare only $20 million for about 480,000 injections, while ranibizumab cost Medicare $537 million for only 337,000 injections. [50] A small study showed no superior effect of ranibizumab versus bevacizumab in direct comparison. [51] The initial results of the larger Comparison of Age-related Macular Degeneration Treatments Trials (CATT) found that the two drugs "had equivalent effects on visual acuity when administered according to the same schedule;" however, serious adverse events were more common in the bevacizumab arm of the trial. [47]

According to a 2012 meta-analysis, the results of several subsequent head-to-head trials found that the two therapies performed equally at restoring visual acuity. [52] [53] A 2012 meta-analysis focused specifically on safety issues concluded that the rates of several adverse events were higher with bevacizumab, although the absolute rates of ocular serious adverse events were low with both therapies: ocular adverse events were about 2.8 times as frequent with bevacizumab than with ranibizumab. [45]

Retinopathy is any damage to the retina of the eyes, which may cause vision impairment. Retinopathy often refers to retinal vascular disease, or damage to the retina caused by abnormal blood flow. Age-related macular degeneration is technically included under the umbrella term retinopathy but is often discussed as a separate entity. Retinopathy, or retinal vascular disease, can be broadly categorized into proliferative and non-proliferative types. Frequently, retinopathy is an ocular manifestation of systemic disease as seen in diabetes or hypertension. Diabetes is the most common cause of retinopathy in the U.S. as of 2008. Diabetic retinopathy is the leading cause of blindness in working-aged people. It accounts for about 5% of blindness worldwide and is designated a priority eye disease by the World Health Organization.

Most of the NEI budget funds extramural research.

<span class="mw-page-title-main">Macular edema</span> Medical condition

Macular edema occurs when fluid and protein deposits collect on or under the macula of the eye and causes it to thicken and swell (edema). The swelling may distort a person's central vision, because the macula holds tightly packed cones that provide sharp, clear, central vision to enable a person to see detail, form, and color that is directly in the centre of the field of view.

<span class="mw-page-title-main">Macular degeneration</span> Vision loss due to damage to the macula of the eye

Macular degeneration, also known as age-related macular degeneration, is a medical condition which may result in blurred or no vision in the center of the visual field. Early on there are often no symptoms. Over time, however, some people experience a gradual worsening of vision that may affect one or both eyes. While it does not result in complete blindness, loss of central vision can make it hard to recognize faces, drive, read, or perform other activities of daily life. Visual hallucinations may also occur.

Bevacizumab, sold under the brand name Avastin among others, is a monoclonal antibody medication used to treat a number of types of cancers and a specific eye disease. For cancer, it is given by slow injection into a vein (intravenous) and used for colon cancer, lung cancer, ovarian cancer, glioblastoma, hepatocellular carcinoma, and renal-cell carcinoma. In many of these diseases it is used as a first-line therapy. For age-related macular degeneration it is given by injection into the eye (intravitreal).

Radiation retinopathy is damage to retina due to exposure to ionizing radiation. Radiation retinopathy has a delayed onset, typically after months or years of radiation, and is slowly progressive. In general, radiation retinopathy is seen around 18 months after treatment with external-beam radiation and with brachytherapy. The time of onset of radiation retinopathy is between 6 months to 3 years.

Joan Whitten Miller is a Canadian-American ophthalmologist and scientist who has made notable contributions to the treatment and understanding of eye disorders. She is credited for developing photodynamic therapy (PDT) with verteporfin (Visudyne), the first pharmacologic therapy for retinal disease. She also co-discovered the role of vascular endothelial growth factor (VEGF) in eye disease and demonstrated the therapeutic potential of VEGF inhibitors, forming the scientific basis of anti-VEGF therapy for age-related macular degeneration (AMD), diabetic retinopathy, and related conditions.

Anti–vascular endothelial growth factor therapy, also known as anti-VEGF therapy or medication, is the use of medications that block vascular endothelial growth factor. This is done in the treatment of certain cancers and in age-related macular degeneration. They can involve monoclonal antibodies such as bevacizumab, antibody derivatives such as ranibizumab (Lucentis), or orally-available small molecules that inhibit the tyrosine kinases stimulated by VEGF: sunitinib, sorafenib, axitinib, and pazopanib.
