Byooviz

Byooviz is a solution for injection into the vitreous humour, the jelly-like fluid in the eye. It can only be obtained with a prescription and must be given by a qualified eye doctor who is experienced in giving injections into the eye.

Treatment is started with one injection of 0.5 mg every month, with regular checks of the patient’s vision and examination of the back of the eye, until maximum vision is achieved and/or there are no signs of disease activity. The interval between two injections of Byooviz into the same eye must be at least four weeks. Treatment with Byooviz should be stopped if the patient is not benefitting from it.

For more information about using Byooviz, see the package leaflet or contact your doctor or pharmacist.

Laboratory studies comparing Byooviz with Lucentis have shown that the active substance in Byooviz is highly similar to that in Lucentis in terms of structure, purity and biological activity. Studies have also shown that giving Byooviz produces similar levels of the active substance in the body to giving Lucentis.

In addition, a study involving 705 patients with age-related macular degeneration found that Byooviz produced comparable improvements in the condition to those seen with Lucentis. In this study, the swelling of the macular area after 4 weeks was reduced on average by 108 micrometres in people given Byooviz and 100 micrometres in those given Lucentis. The number of letters patients could recognise on a standard eye test improved by about 10 in both groups after a year of treatment.

Because Byooviz is a biosimilar medicine, the studies on effectiveness and safety of ranibizumab carried out with Lucentis do not all need to be repeated for Byooviz.

The safety of Byooviz has been evaluated, and on the basis of all the studies carried out the side effects of the medicine are considered to be comparable to those of the reference medicine Lucentis.

The most common side effects with ranibizumab (which may affect more than 1 in 10 people) are increased intraocular pressure (pressure within the eye), headache, vitritis (inflammation in the eye), vitreous detachment (separation of the vitreous from the back of the eye), retinal haemorrhage (bleeding at the back of the eye), visual disturbance, eye pain, vitreous floaters (spots in the vision), conjunctival haemorrhage (bleeding at the front of the eye), eye irritation, sensation of a foreign body in the eye, increased lacrimation (watery eyes), blepharitis (inflammation of the eyelids), dry eye, ocular hyperaemia (increased blood supply to the eye, leading to redness of the eye), eye pruritis (itching), arthralgia (joint pain) and nasopharyngitis (inflammation of the nose and throat). Rarely, endophthalmitis (an infection inside the eye), blindness, serious damage to the retina and cataract (clouding of the lens) can occur. 

Byooviz must not be used in patients who may have an infection of the eye or of the area around the eye, or who have severe inflammation within the eye. For the full list of side effects and restrictions of Byooviz, see the package leaflet.

The European Medicines Agency decided that, in accordance with EU requirements for biosimilar medicines, Byooviz has a highly similar structure, purity and biological activity to Lucentis and is distributed in the body in the same way. In addition, studies in patients with age-related macular degeneration have shown that the safety and effectiveness of Byooviz is equivalent to that of Lucentis in this indication.

All these data were considered sufficient to conclude that Byooviz will behave in the same way as Lucentis in terms of effectiveness and safety in its authorised uses. Therefore, the Agency’s view was that, as for Lucentis, the benefits of Byooviz outweigh the identified risks and it can be authorised for use in the EU.

The company that markets Byooviz will provide information packs to patients to help them prepare for treatment, recognise serious side effects and know when to seek urgent attention from their doctor.

Recommendations and precautions to be followed by healthcare professionals and patients for the safe and effective use of Byooviz have also been included in the summary of product characteristics and the package leaflet.

As for all medicines, data on the use of Byooviz are continuously monitored. Suspected side effects reported with Byooviz are carefully evaluated and any necessary action taken to protect patients.

Byooviz received a marketing authorisation valid throughout the EU on 18 August 2021.
