Faricimab Improves Results for Most Patients on Prior Therapy for nAMD

Switching medications may decrease treatment burden and macular fluid

Intravitreal anti-vascular endothelial growth factor (anti-VEGF) injections, including aflibercept, bevacizumab and ranibizumab, have significantly improved outcomes for patients with neovascular age-related macular degeneration (nAMD). However, some disease is resistant to anti-VEGF therapy, causing patients to have residual macular fluid or need frequent treatment.

Approved by the U.S. Food and Drug Administration in 2022, faricimab is the latest agent to be added to the anti-VEGF class. The clinical trials for faricimab in age-related macular degeneration (AMD) were solely in treatment-naive patients, making it difficult to generalize and apply the data to real-world patients, says Sumit Sharma, MD, a retina and uveitis specialist at Cleveland Clinic Cole Eye Institute.

“We wanted to see how our treatment-resistant patients did when they were switched to faricimab after being treated with other agents,” he says.

The resulting study was published in Ophthalmology Retina.

Study methods

The retrospective study assessed Cole Eye Institute patients with nAMD who had been treated with anti-VEGF injections and switched to intravitreal faricimab. A total of 126 eyes of 106 patients were included, with 87% switching from aflibercept.

“Aflibercept has been our top agent for patients with nAMD who are resistant to treatment with bevacizumab,” says Dr. Sharma.

Central subfield thickness (CST), maximum pigment epithelial detachment (PED) height, and the presence of subretinal fluid (SRF) or intraretinal fluid (IRF) were evaluated on the first day of faricimab injection as well as after each treatment.


Increasing treatment interval by up to two weeks

“The most important finding was that patients who were treatment-resistant on aflibercept — having persistent fluid or requiring treatment every four to six weeks — did a little better with faricimab,” says Dr. Sharma.

For most patients, faricimab increased the time between injections by one to two weeks. It also resulted in less macular fluid, as evidenced by a reduction in maximum PED height and mean CST, as well as an increase in patients without SRF or IRF after three injections. Visual acuity remained stable during treatment.

Although adding a week or two between injections may not seem like much, for patients needing injections every four weeks, the number of injections per year would decrease from 13 to eight or nine.

“That’s a significant reduction in treatment burden from the patient perspective,” says Dr. Sharma.

If the study had analyzed treatment-naive patients, a sizable portion may have been able to go 12 or 16 weeks between treatments, he notes.

Complications with faricimab

“Anytime you switch medications, there’s a risk, and there were a few patients in our group who had inflammation after switching to faricimab,” adds Dr. Sharma. “Luckily, they were mild cases, and all of those patients did fine switching back.”


However, most of the 8.7% of patients who changed back to aflibercept did so because of worsening SRF or IRF.

For clinicians who switch their patients to faricimab, expect about 1 in 10 to go back to their original anti-VEGF agent, he says.

Setting patients’ expectations

Dr. Sharma considers faricimab another tool in the armamentarium for treating nAMD.

“I think it’s worthwhile to consider faricimab in our patients if they’re treatment-resistant on aflibercept,” he says.

When counseling patients who are thinking of switching to faricimab, physicians should tell them to expect to see either less fluid or a slightly longer interval between treatments, advises Dr. Sharma. “But they shouldn’t expect to get out to 16 weeks if they’re currently on an every-four-week interval.”
