Dry Macular Degeneration Clinical Trials

Dry macular degeneration clinical trials are becoming more available as new treatments and earlier intervention is being researched. From nanosecond laser therapy of macular drusen to eye injections, these clinical trials treat patients that have intermediate to advanced dry AMD. There are several things you will want to know when considering a clinical trial.

1.  Where is the Study Being Conducted

The clinical trials that are listed at www.clinicaltrials.gov include studies that are offered in the United States as well as abroad. So it is important to look at the location of the study.   Often the study will have several study locations. 

2.  What Phase Is the Study In

dry macular degeneration clinical trials

There are four phases of clinical trials. Phase 1 is the first stage that focuses on safety and recruits the smallest number of participants,  while a Phase 2 is looking more at the effectiveness of the therapy.

A Phase 3 will recruit a larger population and will continue to look at safety and effectiveness and may also evaluate different therapeutic dosages.

Here is a sampling of some current dry macular degeneration clinical trials:

Safety and Tolerability of RPESC-derived RPE Transplantation in Patients With Dry Age-related Macular Degeneration (AMD)

Grown from human eyes donated to eye banks, the Luxa cells are different because they are derived from adult stem cells that are normally present in the adult human eye.   

The RPESC-RPE-4W cells used in the Luxa trial are obtained from donated eyes deposited in eye banks. Cells obtained within 36 hours of the donors’ passing are used to make cell banks that are expanded and frozen for subsequent transplantation.

“If we can successfully repair the RPE layers by cell transplantation, we can potentially provide meaningful improvement in vision and in the lives of patients suffering from dry AMD, which is our goal.”

Jeff Stern, MD, PhD, scientific co-founder of Luxa and the Neural Stem Cell Institute

Mitochondria and Macular Degeneration

"Mitochondrial dysfunction is believed to be a significant contributor to the progression of dry AMD, making the mitochondrial network an attractive target to improve retinal function and mitigate disease burdens in this patient population."

ReCLAIM-2 is a phase 2, randomized, double-masked, placebo-controlled clinical study to evaluate the safety, efficacy and pharmacokinetics of subcutaneous injections of elamipretide in subjects with dry AMD with geographic atrophy.

The study just completed enrollment with 176 patients. "The primary endpoint of the 48-week study will measure the low-luminance best-corrected visual acuity, which assesses visual function under low light conditions meant to represent dusk or indoor (artificial) lighting. Secondary functional endpoints are change in low-luminance reading acuity, best-corrected visual acuity (BCVA).  Secondary imaging endpoints assessing the rate of progression of the disease include GA area as measured by fundus autofluorescence and optical coherence tomography."

First in Human Study to Evaluate the Safety and Efficacy of GT005

An ophthalmology company that's developing gene therapies in the UK called Gyroscope Therapeutics has launched a Phase I/II clinical trial to slow the progression of central vision loss in patients with late stage dry AMD.  The basis of their research involves the cascading effects of what is called the Complement System - complement system proteins, complement activators and complement regulatory proteins. These molecules stimulate and trigger inflammation and the progression of macular degeneration.

Recent genetic studies have identified and shown that there are gene variants that trigger an overactive complement system which is associated with the degeneration of the macula and progression of AMD.

On September 22, 2020 Gyroscopes Therapeutics Limited announced that the U.S. Food and Drug Administration (FDA) has granted Fast Track designation to GT005 for the treatment of geographic atrophy (GA). "Dry AMD is a life-altering diagnosis and there are currently no FDA-approved medicines available. Research suggests people with dry AMD who have certain CFI mutations that correlate with low CFI levels in the blood have a higher risk of developing AMD,1" said Nadia Waheed, M.D., MPH, Chief Medical Officer. "We are pleased to receive Fast Track designation for our investigational gene therapy for this high-risk group. We look forward to working with the FDA as we advance our clinical program evaluating the safety and effectiveness of GT005."

The multi-center study in the United Kingdom and Boston, Massachusetts will "evaluate the safety, the dose response and efficacy (anatomical and functional visual outcomes) of two doses of GT005 administered as a single subretinal injection in genetically defined subjects with Macular Atrophy due to Age-related Macular Degeneration (AMD)."

GT005 is also being evaluated in a Phase II clinical trial called EXPLORE.

APL-2 Therapy in Patients with Geographic Atrophy 

Robin Guymer, ophthalmologist, retina specialist and deputy director of the Centre for Eye Research Australia is also the principal investigator of the Study of APL-2 Therapy in Patients with Geographic Atrophy (FILLY).  

With 40 testing sites in the United States and Australia, 246 patients were recruited to receive either monthly or every other month eye injections of a new compound APL-2 for 12 months. 

Eligible patients had a diagnosis of geographic atrophy, (GA) due to macular degeneration. 

Phase 2 clinical trial results report, "Patients were given injections either monthly or every other month for 12 months, resulting in a reduction in GA lesion growth of 29 per cent and 20 per cent respectively, compared to control patients.

Additionally, in a , a greater effect was observed during the second six months of the study: a reduction in GA lesion growth rate of 47 per cent with monthly administration, and a reduction of 33 per cent with every other month administration. Based on these positive results, Apellis plans to proceed with Phase 3 studies as soon as possible."

Antibiotic to Treat Advanced Dry AMD

The National Eye Institute is looking to see if a common antibiotic, minocycline, will help those with geographic atrophy. (GA).

Dry macular degeneration has a slower progression of central vision loss due to the degeneration and loss of the retinal pigment epithelial (RPE) cells and photoreceptors in the macula.

According to the description from ClinicalTrials.gov, "While the etiology of GA is not completely understood, inflammatory processes involving the activation of resident immune cells of the retina called microglia is likely to contribute. Minocycline inhibits the activation of microglia which produce inflammatory factors implicated in GA development. The objective of this study is to investigate the safety and possible efficacy of oral minocycline in patients with GA."

Forty participants who have GA in one or both eyes will be enrolled in the study. A 100 mg dose of minocycline will be taken twice daily for 36 months.   To find out more about this study visit:

Non-Damaging Photothermal Therapy for Dry AMD

The sponsor and collaborator of this dry macular degeneration clinical trial are Stanford University and Bascom Palmer Eye Institute.  Eligible participants must be at least 60 years old and have dry macular degeneration and "large high-risk drusen."  The goals of the study as stated by ClinicalTrial.gov are:

1.  To determine if this treatment will reduce macular drusen volume 

2.   Whether treatment will improve visual acuity

3.    If treatment will reduce the risk of conversion to advanced age-related macular degeneration defined as development of choroidal neovascularization (wet macular degeneration)  or geographic atrophy.

Here is a short video explaining how the non-damaging laser unit called Pascal Laser Endpoint Management System can be used in retinal diseases without tissue damage.

This macular degeneration study is a double blind placebo controlled study meaning that  participants will be randomized to receive the photo thermal therapy and others a "sham" laser treatment.
