Scientists at the University of Birmingham have been developing an alternative treatment—this one in the form of an easy-to-use eye drop. After proving the drop has a similar therapeutic effect as injections do in rodents last year, the team began investigating the drug in rabbits and pigs, which have eyes that are similar to those of humans.
The team discovered that the drop can deliver an effective amount of AMD-fighting drug to the larger mammals. They reported their results in the journal Investigative Ophthalmology & Visual Science.
The eye drop contains a peptide that can penetrate cells in the retina. It is now being developed by a startup in the U.S. called Macregen, according to a statement. The company is working with the University of Birmingham team to complete proof-of-concept studies.
“From the outset, we [realized] that delivering drugs through eye drops would mean that patients can administer their treatment themselves, and this would be less costly, save time for patients and healthcare providers, and reduce the potential complications that can arise from injections,” said Felicity de Cogan, a research fellow at the University of Birmingham’s Institute of Microbiology and Infection, in the statement.
As successful as Lucentis and Eylea have been, improving on them has been challenging. The drugs work by inhibiting the protein VEGF, which subsequently plugs up the leaky blood vessels that are a hallmark of AMD. Regeneron tried combining its drug with the Bayer antibody nesvacumab, but disappointing trial results prompted the partners to scrap a planned phase 3 study last year….
