Let’s Chat About … Patient Registries and My Retina Tracker

Join the My Retina Tracker® registry and you’ll be contributing to science by driving research to help improve your quality of life and to find treatments and cures for Leber congenital amaurosis (LCA) and other rare inherited retinal diseases (IRDs). 

The free and secure online registry launched six years ago by the Foundation Fighting Blindness is being updated and your feedback is needed. The organization currently is conducting a “user-experience” survey of its membership to glean new ideas to make the registry more effective for patients and for researchers, according to the Foundation’s Todd Durham. 

Now, through at least the end of June, you can contribute by taking the survey on the registry’s website and updating your profile. If you’re not already part of the registry, click here to join. The global registry has more than 18,000 members and is open to anyone with an inherited retinal condition and/or adult caregivers of children.

As the Foundation’s Vice President of Clinical & Outcomes Research, Durham is responsible for directing the organization’s Clinical Consortium of retinal experts, developing strategies to enhance product development, partnering with industry, and providing technical input on partnered programs and investment decisions.

The Foundation is the world’s leading private funder of retinal disease research and collaborates with patients, caregivers, researchers, and biopharmaceutical companies. That funding has been a driving force behind the progress toward cures, including the identification of more than 270 genes linked to retinal disease, and the launch of 42 clinical trials for potential treatments.

Durham discussed the patient registry and survey in our May webinar episode: “Let’s Chat About … Patient Registries and My Retina Tracker®.” Sofia Sees Hope Director of Marketing and Communications Elissa Bass moderates the free monthly webinar series. You can watch the webinar here. 

Durham earned a Bachelor of Science in Public Health, a master’s in biostatistics, and a PhD in health policy and management (Decision Science and Outcomes Research) from the University of North Carolina School of Global Public Health. He has more than 25 years of drug-development experience.

Understanding Patients and Retinal Disease Through Data

A patient registry is a planned collection of data around a disease. My Retina Tracker distinguishes itself from others by focusing on inherited retinal degenerations or diseases with the purpose to understand genetics, prevalence of conditions, and impacts of IRDs on individuals’ lives. 

The registry also enables researchers to find people for clinical trials, especially challenging work in the rare disease world of LCA and other IRDs.

Registry subsections include assistive devices, driving, visual symptoms, and the recently added “My Health Today,” a series of questions developed by the National Institutes of Health (NIH) to assess physical and mental health.

To become a member, click on ‘Register Now’ and follow the prompts to establish a username and password and to answer questions to build your personalized retinal health profile. You are then guided through a series of questionnaires developed by retinal clinicians, geneticists, genetic counselors, and rare inherited retinal disease researchers.

The registry becomes your personal retinal health record, updated by you and your doctors. Your history and testing results create a critical resource in tracking the progress of your disease and becoming part of a comprehensive database. It employs state-of-the-art technology to protect privacy and adheres to the highest standards of confidentiality and ethics.

Your disease information is accessible only to you, Foundation registry staff, and researchers who meet a rigorous scientific review application process to use the data for studies and to reach individuals to participate in clinical trials, Natural History studies, or focus groups. Your personal information is never shared with researchers.

It’s important to update your profile because the data unique to those living with LCA and other IRDs gives researchers a trove of opportunities for studies. The more complete the profile, the more likely you are to be contacted about a research opportunity. 

“Many of our research collaborators may approach us with a research idea and a certain criterion they want to apply to their study, and we use as much data in the profile as we can to help find the right target for that study,” Durham said. “As your vision changes, as your life situation changes, we’d like to know the milestones along the way. That’s informative information.”

Enhancing Patient Registries through Survey Feedback

An important improvement to the registry would be the ability to highlight to its members the research emanating from the information given by registrants. Completing the survey and giving specific feedback will help accomplish this.

“The key focus right now is delivering back to the members some information that they find useful, that shows that they are contributing to science.”

The Foundation also wants to engage its registry membership more regularly with information tailored to profiles.

“Speaking with a number of individuals involved with the Foundation, they say ‘it sure would be nice if when I tell you that my gene is, let’s say, EYS that you could tell me more about people like me.’ We’re looking into some ways that we can collect that data, put it in a way that’s understandable, digestible, presentable, and make that available to our membership, the registry.”

Results from the user-experience survey will be central in making the registry more valuable.

“As much as possible we really want folks’ feedback and, in this survey, we ask about their experience not just with the registry itself, but also with our genetic testing program, which many people have been able to take advantage of.

“We’re in a rapidly evolving research field; we’ve got new therapies coming all the time. To me, it’s important to put in mechanisms where we can learn along the way, and we’ll want to get as many indicators as possible.” 

Patient Registries: Making a Difference Through Research

Every month, six or seven researchers contact the Foundation for access to the registry, Durham said. One proposed study would look at patient experience with genetic testing and counseling. 

“How did that counseling session change the way they view their life, what impact did it have on them? This is very promising and interesting research. When we saw this, we thought this is very relevant for our members and for our community in general because we believe genetic testing is hugely important. 

“From my conversations with individuals, that moment when you have the clarity of a genetic diagnosis is kind of a day that you remember. It is now the time where I can at least ask the question, ‘what is the typical progression for folks like me? Are there research opportunities for me? What are the research prospects for people like me?’

“All this research can make a big impact.”

One project using registry data produced an analysis estimating the cost of illness for an IRD – an economic burden of up to $31.7 billion in the United States.

“When you see the paper as to the estimated cost to the U.S. of the IRDs, that study result came because people participated in the My Retina Tracker registry.” 

The Foundation plans to prepare reports or peer-reviewed publications out of the registry over the coming years to show the research community how much can be learned about what life is like with an IRD.

Patient Registries Put People at the Center of Research 

The registry also is an integral part of patient-focused drug development, a national concept organized by the U.S. Food and Drug Administration to put patients at the center of research. 

“This is a unique thing that the Foundation is doing to make sure we don’t lose sight that there are humans, there are people and lives that are impacted by research.” 

In a partnership as part of this patient-focused research, Sofia Sees Hope and the Foundation conducted intensive workshops on the CRB1 and IQCB1 genes that included the voices and perspectives of patients and their families, along with dozens of leading experts.

Another example of patient-centered research is the collaboration between the Foundation and the biopharmaceutical industry to study males with X-linked retinitis pigmentosa (XLRP), an incurable genetic disease that causes blindness in men and affects about one in 15,000 people.

“We’ll be surveying people through our registry and then convening a panel of experts and inviting the FDA to attend a workshop about results of the work and also inviting affected individuals and their caregivers to tell us what life is like with XLRP,” Durham said.

Living in a Time of Hope

Retinal research has come far, with more than 40 clinical trials underway.

“This is an exciting time, and I don’t think it’s an exaggeration to say, which should be a great time of hope, because 10 years ago there were not a whole lot of treatments to talk about,” he said, “and now even as the Foundation stands, we struggle to keep up with all the latest news amongst therapy developers.”

Not all therapies work out, but researchers learn a lot in the process of product development.

Also, conditions once thought to have been impossible to treat now have multiple therapeutic approaches, with even more in the pipeline.

Durham said, for example, neuroprotection, which is the relative preservation of neuronal structure and/or function, and neuroprosthetics,* implantable medical devices that provide some degree of vision to people with blindness.

“If we can just slow down the further degeneration of the photo receptors that could be really helpful, that could add hopefully years to vision. Gene therapy has the potential in many cases to restore vision that was lost. And you have even new technologies for later-stage disease, like (visual) neuroprosthetics.

“It’s pretty amazing technology that’s coming out.”

Let’s Chat About … Genetics and Inherited Retinal Disease

You or your loved one just received a clinical diagnosis of Leber congenital amaurosis (LCA), a rare inherited retinal disorder caused by a mutated gene. The disease causes severe vision loss at birth and affects the peripheral rod cells that allow night vision and the central cone cells  responsible for fine detail and color vision. What now?

The next most important step is to get a genetic test for a confirmed genetic diagnosis to clarify the underlying genetic explanation of the disease. Finding the specific gene causing the defect is critical for moving forward with research and treatment.

Genetic counselors like Emily Place help navigate the complex world of gene mutations, genetic testing, and genetic diagnoses. She is among the more than 4,700 certified genetic counselors nationwide, and she specializes in counseling families living with inherited retinal diseases (IRDs). 

Place, a Licensed Genetic Counselor and Research Study Coordinator at Massachusetts Eye and Ear (MEE), discussed her role in the ever-evolving world of genetics in our March webinar episode: “Let’s Chat About…the ins and outs of genetic testing.” Sofia Sees Hope Director of Marketing and Communications Elissa Bass moderated the monthly series, which you can watch here. 

Place began her work at MEE’s Ocular Genomics Institute (OGI) in 2011, about the same time the first clinical trials were underway for a vision-improving gene therapy. Six years later, researchers identified, and regulators approved LUXTURNA®, the first gene therapy treatment for an inherited disease, and specifically for LCA2-RPE65, one of the more than 25 gene mutations associated with LCA.

Before OGI, Place worked as a pediatric genetic counselor at Children’s Hospital of Philadelphia, the same place researchers and Spark Therapeutics developed that RPE65 gene therapy.

She earned a Bachelor of Arts in Biology from the University of St. Thomas and her master’s degree in Human Genetics from New York’s Sarah Lawrence College, which in 1969 established the first graduate degree program in genetic counseling. With ever-expanding genetic studies, the profession dramatically increased with more than 50 programs now in the United States.

Basic Genetics

The Human Genome Project (HGP) began in 1990 as an international, collaborative quest to map and understand all the genes of human beings and their roles in health and disease. The project, completed in 2003, revealed there are probably about 20,500 human genes, referred to collectively as our genome, according to the National Human Genome Research Institute.

Scientists have since identified more than 30,000 genes in our body and more genetic causes of inherited conditions, and more research remains to be done to better understand the causes of inherited conditions and to identify more genes.

“Genes are instructions or blueprints that tell us how to grow and function,” Place said.

This genetic information is organized in our chromosomes and can be found in every cell of our body. 

More than 200 genes have been identified as playing a specific role to help retina function.

“These inherited retinal conditions can arise because of a genetic variation or change within a gene that we know is important for retinal function and, what we really mean here, is that this genetic change is changing the genetic code in some sort of way that is causing the gene not to function properly within the retinal cells.”

With a few exceptions, she said, a general eye exam will not reveal the underlying genetic explanation for retinal disease.

“That’s where genetic testing is necessary to rule in or identify which one of these 200-plus genes could be the underlying explanation and thus, more definitively rule in an inherited condition and provide a more definitive specific genetic diagnosis.”

The most common pattern for inherited retinal diseases to occur is a recessively inherited condition, the result of inheriting a genetic variation in two copies of the gene, one of those copies inherited from mom and one from dad.

“In these recessive conditions, generally, there may be no family history of anybody else in the family with similar conditions, and that’s because individuals can be carriers, and they may carry one copy of a variation and one copy of their gene, but they have another that can compensate. 

“Carriers can be asymptomatic and run through multiple generations and not even know that they’re carriers, and it isn’t until two carriers meet that there’s even a chance for both of them to pass on the genetic change.”

Specific Genetic Identification Versus No Clear Explanation

Counselors help in multiple ways as a family or patient is working toward a genetic diagnosis. Place can begin counseling families before testing, gleaning family history details, reviewing complexities of different inheritance patterns, and looking into what can and cannot be learned from testing.

“It’s also exploring with patients and families whether this is the right time for genetic testing. Is this something that the individual is ready to move forward with or is it something that maybe should be discussed or pursued a later time?”

Counselors can work with families after testing, reviewing the result, whether it be that the testing identified a specific gene or that no clear explanation was found, which happens 30 percent of the time, Place said. 

No clear explanation could mean a negative result or an inconclusive result. A negative result can mean no genetic variations were identified. An inconclusive one could be that variants were identified within one to two genes, and the lab does not currently have enough data to classify those variants as disease-causing, but they also cannot be ruled out as not disease causing, she said.

“Sometimes additional testing of other family members may be helpful in resolving the significance of those variants, or that it’s going to take some time and more genetic knowledge is needed to better classify those variants.”

Working with a counselor also helps sort out next steps to take, including the possibility of periodically checking back with your genetic counselor to see if more recent research has updated results or new testing options.

“A True Privilege” To Create Relationships

Long-term relationships can develop between counselors and families after testing. If the test identified a specific gene, they discuss the result, assess the risk of other family members having the mutation, coordinate whether they should get tested, and maintain communications going forward about potential genetic-related treatments and therapies. 

Place said it may not be the case with every counselor, but long-term relationships with families are the norm in her work.

“I think every clinic and counselor’s experience will be a bit different. I have the true pleasure of working within an IRD clinic where we’ve had long-term relations with the families, and I get to see families back over the course of their visits with us, and so it is a true privilege to be able to create these longer relationships with families.”

Her approach to testing is that a patient diagnosed with any type of IRD should undergo a full IRD panel testing so as not to miss a particular gene. 

She also said it’s important for the patients and families to have back-and-forth relationships with their ophthalmologists.

“It’s definitely a two-way relationship, continuing to stay engaged with your providers, but your provider also thinking about being on top of the different testing options that are available.”

Getting Genetically Tested

A person needs a doctor’s order to be genetically tested. Diagnostic testing is done on a patient’s blood or saliva sample at a clinically certified lab that analyzes a specific set of genes identified to be the cause of retinal condition.

Whether you are living in a rural area or a city, you can find genetic counselors and information about testing through the National Society of Genetic Counselors (NSGC) or local genetic providers through the American College of Medical Genetics and Genomics (ACMG).

ACMG is a place to locate a Medical Geneticist (MD/physician), as well as medical genetics clinics. The search ‘Find a Genetic Service’ can be used to locate a genetic professional.

Search engines in both organizations bring up regional options by entering your zip code. Counselors can meet in-person with patients or, depending on the clinic, via telehealth, by phone, video conferencing, and other virtual methods.

Testing resources also can be found through medical or clinical genetics’ departments in your hospital system.

Also, Sofia Sees Hope has donated more than $140,000 to fund free genetic testing for individuals with inherited retinal disease through the My Retina Tracker® program, launched and managed by the Foundation Fighting Blindness. The program is an open access, no-cost genetic testing program for individuals with a clinical diagnosis of an IRD.

“So much has changed in terms of access to genetic testing for inherited retinal diseases over the last several years, and it’s more available to patients than it ever has been in the past. I would say this is really a good time to work toward getting a genetic diagnosis – getting genetic testing if you haven’t had it or re-engaging with your providers if you’ve had testing years ago without a positive result and discuss updated testing options. 

“There are resources out there and available, so there are plenty of individuals like me that are available to help facilitate testing or get you in touch with the right counselor or medical geneticist to help facilitate testing for you.”

‘Give Us Hope’: Bringing Together Leber Congenital Amaurosis Researchers and Patients

Promising gene therapy research – characterized as having a good potential to restore vision – is underway to help visual impairment caused by a form of Leber congenital amaurosis (LCA) attributable to a mutation in the IQCB1 gene.

Amy Laster, PhD, Vice President of Science and Awards Programs for the Foundation Fighting Blindness, shared the research news as part of a recent LCA Research Update webinar summarizing results of an IQCB1/NPHP5-associated retinal disease Scientific Advancement Workshop conducted a week earlier.

Laura Manfre, Sofia Sees Hope Co-Founder and President, said more than 40 leading experts in ophthalmology and gene research gathered for the virtual workshop to share research and patient perspectives and identify the next steps to advance treatment for the patient community. Hope in Focus ( formally Sofia Sees Hope) and the Foundation Fighting Blindness hosted these Scientific Advancement Workshop to widen the circle of research awareness, build a framework or platform for sharing knowledge, foster collaboration among stakeholders, identify gaps, and set priorities for action. The format was based on a similar program run earlier for the RDH12 gene.

“Our objective today is to engage you and our IQCB1/NPHP5 community to seek to advance treatment for ourselves and our loved ones…” Manfre said in her introduction. 

“There are no easy answers and there are no quick or fast solutions; just wanted to set that expectation up front even as we are very excited to share the news that we have for you.”

Early-stage translational research

The reported results are from early-stage translational research, which involves moving discoveries from basic science and animal models to applying them in human clinical trials.

The news comes after a successful proof of concept or feasibility study by Dr. Gustavo D. Aguirre, VMD, PhD. He is Professor of Medical Genetics and Ophthalmology at the School of Veterinary Medicine, University of Pennsylvania, and he identifies dogs with inherited eye and retinal degeneration. 

Dr. Aguirre will be presenting results of his proof of concept gene therapy study on LCA-NPHP5 dogs in a paper soon to be published in a peer-reviewed journal. The research is detailed in bioRxiv (pronounced bio-archive), a repository for preprinting papers prior to publication. 

Laster said the study showed that photoreceptors in treated areas had structural improvements and the dogs had improved visual function. 

Researchers sent dogs through an obstacle course under dim light and under bright light. Navigating with their treated eye, the dogs had faster travel times and fewer collisions than when they navigated using their untreated eye.

She called the findings very promising, saying, “We’re excited about these results.”

Laster also cited ongoing clinical studies suggesting that the structure of the central retina or macula is preserved for many years despite having significant loss of vision.

“This, if you will, dissociation between the structure and function suggests that a gene therapy targeted at the central retina not only could work but has a good potential to restore lost vision,” she said. “So we build on this proof of concept and clinical knowledge toward translating these laboratory-based research concepts into clinical trials for patients.”

Next steps

The next steps include designing clinical trials and identifying relevant endpoints and outcomes to measure the safety and effectiveness of the gene therapy.

Webinar speaker Todd Durham, PhD, Vice President of Clinical and Outcomes Research at the Foundation, said the dog model studies began about four years ago. He said it is unknown when clinical trials would begin because more work needs to be done prior to launching them. Durham emphasized the importance of the research results, saying, “They’ve very much ticked off a major milestone in this proof of concept canine model.” 

Scientific workshop participants also learned that Dr. Aguirre and his colleague, Dr. William A. Beltran, DVM, PhD, co-founded a Philadelphia-based biotechnology company called LuxFiat Therapeutics. 

Laster said this would position the scientists to advance the gene therapy into clinical trials and said that the Foundation will continue to do all that it can to accelerate any clinical development.

The Foundation, the largest private funder of research for treatments and cures of blinding retinal diseases, has raised nearly $800 million since its inception and currently funds more than 80 research projects globally. Dr. Laster oversees the Foundation’s preclinical research portfolio consisting of research awards in funding programs that support career development, laboratory-based science research, translational research, and multi-investigator program projects.

In the question-and-answer session, Durham discussed a query from the audience as to whether it was unusual to receive an incorrect diagnosis of retinitis pigmentosa (RP) before later getting a confirmed genetic diagnosis of Leber congenital amaurosis from Spark Therapeutics. 

Durham said it was not unusual and that it was great the audience member got a genetic diagnosis.

“The clinical manifestations of what many ophthalmologists observe when they do an exam can overlap quite a bit from various conditions,” he said. “Ultimately, at the end of the day, the fact that you got a genetic diagnosis is most informative for you, and that’s our hope that there will be more access to genetic testing. Just to reassure you, I don’t think your story is very unusual at all, unfortunately, but hopefully access to genetic testing going forward is going to make that a less frequent story.”

Supporting the Leber congenital amaurosis community

Manfre, responding to a question about help specifically for those with the IQCB1/NPHP5 mutation, said Sofia Sees Hope supports the entire Leber congenital amaurosis community and suggested looking at the website’s Resources page and joining a highly active IQCB1/NPHP5 Facebook group that she joined because her daughter Sofia has the same genetic variant.

Durham also devoted the beginning of the webinar delivering preliminary information from an ongoing patient survey on perspectives of people affected by LCA or RP and their caregivers.  

He said the survey results will be available to the community after final analysis of the data. 

Here are the topics addressed in the survey developed by Sofia Sees Hope and the Foundation:

  • Diagnostic Journey
  • Current Best Corrected Visual Acuity
  • Visual Symptoms
  • Other Related Conditions
  • Worries
  • Impact on Your Family Overall
  • Participating in Clinical Trials
  • Motivations for Participating in a Clinical Trial
  • Anything Else to Share with Researchers.

Under the last topic, a participant responded: “Time is vision. Please hurry for IQCB1. Give us hope.”

“Let’s Chat About …” Webinar Provides Insight Into How the FDA Handles Rare Disease Treatments

Researchers and regulators did not miss a single step in the fast-tracked federal process of developing successful COVID-19 vaccines. And the same goes for fast-tracking gene therapies for rare disease treatments, Dr. Wiley A. Chambers II of the U.S. Food and Drug Administration said during a recent webinar hosted by Sofia Sees Hope.

As the Supervisory Physician in the FDA’s Division of Ophthalmology, Dr. Chambers discussed vaccines and processes necessary for drugs to be approved for human use in our February 16 webinar episode: “Let’s Chat About…What it takes to receive approval for a new treatment for rare disease.” Sofia Sees Hope Director of Marketing and Communications Elissa Bass moderates the free monthly webinar series. You can watch the webinar here.

Dr. Chambers joined the FDA in 1987 as a primary reviewer for ophthalmic drug products and in 1990 became a Supervisory Medical Officer for Ophthalmologic Drug Products. He has supervisory responsibility for the clinical review of ophthalmologic drug products and ophthalmic therapeutic biologic products submitted to the Center for Drug Evaluation and Research.
He has clinically reviewed more than 100 ophthalmology drugs that have received FDA approval, including the first gene therapy, LUXTURNA®, approved in December 2017. The drug – administered through subretinal injection – is a human-engineered virus containing a healthy version of the RPE65 gene that causes blindness in patients with a form of Leber congenital amaurosis (LCA) called LCA2 (RPE65).

Vaccines: “We’ve Got That Down”

Talking about the recently authorized COVID-19 vaccines, Dr. Chambers said it wasn’t a matter of starting from scratch.
“We know how to make vaccines. We’ve been making vaccines for over a hundred years. We make new vaccines every year. The flu shots that come out are a change in the vaccine every year and we put a vaccine out every year that’s specific to different strains of the flu. Every year. So, we’ve got that down.”

The process did differ in two aspects because of the urgency to quell the pandemic.

“What happened with COVID is the federal government said, ‘You companies go make the vaccines. We’re still going to go through the normal process of testing it, having the FDA go and review it, but don’t wait to see if the product works or not before you make up all those doses. Make them now. And we’re going to pay you for them whether it works or not.’

“So, the companies went and did that. We didn’t skip any steps. We know how to make vaccines. We did what we typically know. We made a series of vaccines and at the same time the companies were mass-producing, as everybody would suggest now, not enough, but made a number of doses out so that when the products got approved, they already had doses made. They didn’t have to start manufacturing doses.”

The second distinction is COVID-19 – which has killed more than 550,000 Americans and more than 2.6 million people worldwide – created a public health emergency requiring urgent mitigation.

Rather than getting FDA approval or clearance, COVID-19 vaccines received Emergency Use Authorization (EUA), one of several tools the FDA is using to help make certain medical products available quickly during the pandemic. Under an EUA, the FDA makes a product available to the public based on the best available evidence, without waiting for all the evidence that would be needed for FDA approval or clearance.

EUAs are effective until the emergency declaration ends, and they also can be revised or revoked by the FDA as it continues evaluating available data and patient needs during the public health emergency.

Developing gene therapies to improve vision also meets fast-tracking requirements because vision loss is considered serious. Fast-tracking gene therapy in ophthalmology means extra meetings and FDA communication.
“But you’re not skipping any steps at all,” Dr. Chambers said.

Improving Visual Acuity

The FDA is a gatekeeper requiring that a product be safe and efficacious for its intended population before it can be marketed for human use. Dr. Chambers regularly talks with patients and solicits comments from groups about what is important to them in the search for potential treatments or cures. The information then can be modified into endpoints, or outcomes, measured scientifically through clinical trials.

“We strive to approve products that are going to benefit patients. That’s who’s going to take them. That’s who they’re for, that’s what we’re trying to go and match.”

Dr. Chambers said his personal preference is cures.

“I like diseases to go away. My endpoint, if given the choice, would be to have something go away. But I’ve got to have a product that’s capable of doing that too, so there’s a reality that sets in that I may not get a product that cures, that does everything I would like it to go and do, but we strive for as many of those things as possible and to then try to include them in the trials.”

As an example, he cited visual acuity (clarity of vision) and the ability to drive.

“For better or worse, in the United States, if you want to be independently mobile, as far as living alone in many parts of the country, you have to be able to drive…and every state in the United States has a visual acuity value that if you’re not at the visual acuity or better, you can’t get a driver’s license…

“We think visual acuity is an important thing to be able to improve for patients. Not because they say they want it but because we know if they don’t achieve that level, they’re not going to be able to drive and they’re not going to have the mobility that we know people want.”

Whether someone can see better in some aspect is an important endpoint, even if it means vision is not completely restored.
“I frequently make the comment that my head is going to hurt just as much if I get hit by a ball that I saw or that I didn’t see. If I have a blind spot and I can now not see a ball coming to me and I get hit with that ball, it’s going to hurt. It would have been nice if I had had the full field of vision so that I could see the ball coming and avoid it. So, if I improve my field of vision, even if it’s not dead center, even if it’s not visual acuity, it’s still a benefit to me.

“You’ll see us potentially approve products on things less than fixing the whole thing, but fixing some portion, and again, we’re absolutely open to suggestions by people of things that they think benefit them that we could use as endpoints.”

Research Models

Mice and rats, cats and dogs, rabbits and monkeys – they all play important roles in developing new treatments and drugs. With inherited retinal disease, dogs take the cake.

Researchers use animal models that most resemble humans, and in the case of LCA, studies showed dogs gained improved vision, leading to the federal approval of the groundbreaking drug LUXTURNA®.

Lancelot, a Briard descended from an ancient breed of large herding dogs in France, carried the same RPE65 gene that caused his blindness.

By contrast, rats would not make for good study models in retinal research because they do not have a macula.
“Rats are more interested in going around in the dark. Their eyes are different,” Dr. Chamber said. “You want to pick an animal that has similar receptors in that species.”

Lancelot and his cousins paved the way for FDA approval of the first-ever gene therapy for inherited disease in humans.

Road to Approval through Clinical Trials

The goal of the FDA is to approve a product proven to be safe and efficacious. The product’s potential adverse events are weighed against its benefits in the balancing act of risk versus reward.

The agency regulates interstate commerce, acting as a gatekeeper for any product intended for human use. Because a biotechnology company probably wants to ship the investigational drug to clinical investigators in many states, it first must seek an exemption from that legal requirement. The exemption is granted after the company submits its research for review.
“If we say nothing, they’re allowed to proceed. If we have an objection, we tell them in 30 days.”

The company can move forward with trials after the FDA assigns an Investigational New Drug (IND) number.

Beware of phony trials, Dr. Chambers said. The website clinicaltrials.gov lists both trials that have been issued an IND number and those overseen by the FDA. It also lists trials not reviewed by the FDA.

“First thing: Ask what the IND number is,” he advised. Dr. Chambers noted that clinical trials, for better or for worse, are never conducted for the people in the trial. They are geared to inform what is going to happen in the future with the product.
Rare diseases – such as the more than 25 forms of LCA and other rare inherited retinal diseases (IRDs) – present bigger challenges in finding participants for clinical trials because the rare disease community inherently represents fewer people. The definition of a rare disease in the United States is one affecting fewer than 200,000 Americans.

If only 30 people are studied, you are likely to see adverse events that occur in 10 percent or more of individuals, he said. If you study 300, adverse events can be picked up at a rate of 1 percent or above.

“It’s all about the numbers, numbers, numbers, numbers…It’s a numbers game.”

The process wends its way through more protocols, comparisons, studies, and trials until a company submits a marketing application reviewed by experts at the agency.

The FDA may hold Advisory Committee meetings for public comment from external reviewers, special government employees, patients, consumers, and advocates. In the case of LUXTURNA®, Sofia Sees Hope Co-Founder and Board Chair Laura Manfre testified at an Advisory Committee meeting on behalf of Spark Therapeutic’s application.

FDA oversight does not end after it approves a drug and a biotechnology company begins marketing it for human use.

“We now start monitoring for adverse events that might occur with the product,” Dr. Chambers said.

The process of receiving federal approval of products for human use can be long and expensive: LUXTURNA® research, development, and approval took 12 years and $500 million. The rewards, though, can be priceless, in helping children and adults see the world in a new light.

Working to Create Rare Disease Advisory Councils in all 50 States

Fifteen states done, 35 to go.

Fifteen states have established a Rare Disease Advisory Council (RDAC) to give the rare disease community, including those living with Leber congenital amaurosis (LCA), a stronger voice in state government. Another dozen states are actively working to establish RDACs this year.

With assistance from the National Organization for Rare Disorders (NORD), patient organizations, such as Hope in Focus (formally Sofia Sees Hope), and the broader rare disease community, RDACs around the country work to help states strategically address barriers faced by people living with rare diseases. The councils give stakeholders an opportunity to make formal recommendations to state leaders on critical rare disease issues, including increased awareness, diagnostic tools, and access to affordable treatments and cures.

Sofia Sees Hope, based in Ledyard, Conn., annually gives information to legislators on the Connecticut General Assembly’s Public Health Committee, letting them know that rare disease advocates and those living with a rare disease, need state and federal support in crafting legislation to help the rare disease community. 

The last day of February each year is officially Rare Disease Day, a time to raise awareness among the public and decision makers about rare diseases and their impacts on patients’ lives. NORD sponsors Rare Disease Day in the United States, alongside its sister organization, the European Organization for Rare Disorders (EURODIS), which organizes the official international campaign.

Find out here what is happening globally in celebration of Rare Disease Day. 

7,000 Rare Diseases in the U.S.

A disease is defined as rare in the United States if it affects fewer than 200,000 Americans. LCA and other inherited retinal diseases (IRDs) are among the approximately 7,000 rare diseases that exist nationally, affecting 1 in 10 people. These diseases include more than 500 types of rare cancers and all pediatric cancers. 

Between 25-30 million Americans live with a rare disease, including about 300,000 in Connecticut. 

NORD’s Connecticut Rare Action Network, along with other such groups nationwide, will highlight RDACs as part of its virtual celebration of Rare Disease Day 2021. Connecticut’s Rare Disease Day celebration will be at 9 a.m. ET, Friday, Feb. 26. You can register to participate in this free event by clicking here. 

NORD also just released its sixth edition of its State Report Card* that analyzes the 50 states and Washington, D.C., on eight policy issues that impact the rare disease community. The organization launched its report card project to evaluate the effectiveness of states serving people with rare diseases.

Each state has its own report card that addresses Medicaid Financial Eligibility, Medicaid Nutrition, Newborn Screening, Prescription Drug Out-of-Pocket Costs, Protecting Patients in State Medicaid Programs, Protecting Patients in State-Regulated Insurance, Rare Disease Advisory Councils, and Step Therapy (trying less expensive options before “stepping up” to drugs that cost more).

RDACs advocate for patients and caregivers

State governments make decisions every day affecting the rare community. They play critical roles in ensuring access to health care providers, services, and treatments needed to thrive, along with the design of their Medicaid program benefits, and regulation of some insurance plans. The councils offer forums for discussion about these issues.

Learn which states have Rare Disease Advisory Councils

As one Connecticut legislator said at a previous celebration, having one day to recognize rare diseases is not enough. 

“It needs to be Rare Disease Day every day in the state of Connecticut,” said State Rep. Jonathan Steinberg, co-chairman of the General Assembly’s Public Health Committee.

Connecticut Volunteer State Ambassador Lesley Bennet  – along with ambassadors nationwide, doctors, researchers, advocates, caregivers, patients, legislators, and business leaders – take this time to advocate state-by-state for better resources and outcomes for people living with rare diseases.

Bennett said many of their patients have difficulty getting access to services because people don’t understand the disorders. 

Patients, caregivers, families, and providers in North Carolina created the first RDAC six years ago; 15 states have active councils with1 2 more on their way toward fruition, for a total of 27 states.

Another 23 states, including Connecticut, do not have such councils but efforts continue through NORD’s Project RDAC, launched last fall. Connecticut established a task force to study whether to create an RDAC, but the group disbanded in 2019. 

Check out this map to see if your state has an RDAC or if NORD is working on legislation to create one. To start an effort in a new state, go to RDAC@rarediseases.org. 

Council composition varies from state to state in size, duties, and accountability requirements. It also depends on the type of entity that houses the RDAC, such as a state department of health or a non-profit organization.

A council typically comprises various stakeholders, including patients, caregivers, doctors, insurers, biotechnology companies, researchers, and state officials.

Project RDAC aims to optimize the existing councils and increase the number of groups nationwide by opening collaborative opportunities among the councils, creating educational resources to guide them, and helping more states pass legislation establishing high-functioning councils.

‘Let’s Chat About …’ Webinar Offers LCA Overview and Updates on Clinical Trials

In the debut of Hope in Focus (formally Sofia Sees Hope) ‘Let’s Chat About …’ monthly webinar series, Ben Shaberman of the Foundation Fighting Blindness, provided his Zoom audience with a plethora of information about Leber congenital amaurosis (LCA), highlighting some of the more than 40 clinical trials underway to find treatments and cures for LCA and other rare inherited retinal diseases (IRDs) and giving updates on promising preclinical research. 

The recorded webinar aired 1 p.m. Wednesday, Jan. 27, 2021, and can be seen here. Elissa Bass, our marketing and communications director, moderated the session.

Shaberman, Senior Director, Scientific Outreach & Community Engagement, stumbled across a science writing position at the Foundation Fighting Blindness 16 years ago without a clue about retinas or blindness. He called his move to the Foundation serendipitous. He knew he made the right choice after hearing retinal researcher Dean Bok, PhD, tell attendees at a 2005 Foundation conference how he was drawn to the field by the seduction of the retina’s myriad complexities and inner workings.

Shaberman, too, felt pulled by the intriguing science of the retina.

As such, so are the 27 forms of LCA that cause varying kinds of visual impairment within each gene mutation and within each affected person. An estimated 8,000 people in the United States have LCA.

The path of retinal research

Shaberman took his audience from the beginnings of identifying the RPE65 gene in 1993 and learning shortly thereafter it could lead to LCA, to using mice models and later studying Briard dogs that had the same gene mutation that caused LCA in humans. A clinical trial at Children’s Hospital of Philadelphia led to the 2017 FDA approval of the breakthrough gene therapy LUXTURNA®, developed by Spark Therapeutics. The drug successfully improved the vision of many of the LCA2-RPE65 patients who received the treatment through subretinal injections.

When children receive an LCA diagnosis, their families should find a good retinal specialist, get regular exams, and ultimately get a confirmed genetic diagnosis to be on the path to more specific information and research into that form of LCA, Shaberman said.

Families also should register with the Foundation’s My Retina Tracker®, a free and secure online registry that facilitates getting a confirmed genetic diagnosis by making registrants eligible for free genetic testing.

The registry becomes your personal retinal health record, updated by you. It employs state-of-the-art database technology to protect privacy and adheres to the highest standards of confidentiality and ethics. 

It also notifies registrants of clinical trials and gives researchers access to their disease data – not their personal information – to advance research and therapy development associated with LCA and IRDs. 

Reading research publications and attending events sponsored by the Foundation and by Sofia Sees Hope also provide opportunities for families to interact and learn the latest research. Shaberman and Bass encouraged people affected by LCA and their families to contact them, respectively, through the Foundation’s website and/or the Sofia Sees Hope website for specific information on clinical trials or other questions and concerns about living with LCA. 

“Yes, it’s work,” Shaberman said. “You have to be your own advocate and your own child’s advocate, but more and more information is becoming available, and that’s the good news.”

More than 40 clinical trials underway

Shaberman also reviewed some of the more than 40 retinal clinical trials in the pipeline for LCA and other IRDs:

Reflecting on the Trajectory of IRD Research

When I joined the Foundation Fighting Blindness as a science writer in 2004, I really didn’t know what I was getting into. I knew nothing about the retina, let alone the complex and diverse world of rare inherited retinal diseases (IRDs) that includes Leber congenital amaurosis (LCA). But the research for treatments was cutting-edge and compelling, so I was excited to dive in and learn.

My early assignments were writing about laboratory studies coming out of academic labs. There were virtually no companies in the IRD space and only one or two clinical trials underway for emerging therapies. But there were a lot of studies of genetically engineered mice and rat models of IRDs for gaining a better understanding of disease pathways and testing potential treatments.

Truth be told, I often wondered if and when rodent-tested therapies were really going to make it into human studies and out to the people losing vision. But the scientists conducting the research were mind-blowingly smart and innovative, so I figured they knew what the heck they were doing. With a master’s degree in poetry, who was I to judge?

Fast forward about four years: I was in my hotel room in Fort Lauderdale – there for the annual Association for Research in Vision and Ophthalmology conference – when my manager called and told me three research groups just reported vision improvements in young adults treated with RPE65 gene therapies in Phase 1/2 clinical trials. That was the breakthrough we’d all been waiting for.

People, rather than animals, with severe vision loss were now seeing significantly better. It was the first time an IRD treatment had worked in humans. I will never forget the headline for the article I immediately wrote: “Now They See.” (Note: One of those RPE65 gene therapies later became LUXTURNA®, the first FDA-approved treatment for the eye or an inherited condition.)

After many years of painstaking work, our hope for treatments and cures had finally begun evolving into promise.

There have been several other aha! moments in the ensuing years, but I distinctly recall cathartic encounters at the 2019 American Society of Retinal Specialists in Chicago. As I perused the snack table during breaks (the accomplished snacking professional that I am), several representatives from biotechs developing IRD therapies – companies I’d never even heard of – came up to introduce themselves to me and tell me about their emerging IRD treatments. They didn’t know me or my role, nor had I previously known them; they were just eager to connect with someone from the Foundation Fighting Blindness to get on our radar screen.

I realized then I couldn’t keep track of all the companies (dozens) focused on IRDs and clinical trials (40-plus) underway for potential IRD treatments. But being overwhelmed felt incredibly good, and it meant more good news likely was on the horizon for saving and restoring vision.

While mouse studies are as critical as ever, I can’t remember the last time I wrote an article about one. That’s because most of my writing is now dedicated to reporting on advances, including encouraging vision improvements, being made in human studies.

Make no mistake: Much more work needs to be done before we eradicate the myriad IRDs affecting millions of people across the globe. And, of course, we cannot get more therapies across the finish line fast enough. But when I look at how incredibly far we’ve come since those early days of mice and rats, I have no doubt we are well on our way to breaking many more ribbons soon.

Nearly Three Years Later, LUXTURNA®™ Treatments Continue to See Success

Since its launch in March 2018, breakthrough gene therapy LUXTURNA®™ continues to be successful in helping improve vision in people with inherited retinal disease due to mutations in both copies of the RPE65 gene and viable retinal cells as determined by a healthcare professional. The therapy treats LCA2, known as LCA/RPE65, one of more than 25 forms of Leber congenital amaurosis. 

The drug – developed by Spark Therapeutics and a team of retinal research superstars that included Dr. Katherine A. High  and Dr. Jean Bennett – came to fruition after 12 years of research and millions of dollars in investment. 

Spark Therapeutics could not comment on the number of people who have received the gene therapy, but spokesman Kevin Giordano recently said the company has shipped well over 200 vials of the therapy since the U.S. Food & Drug Administration approval in December 2017. One vial of the drug treats one eye.

Trained retinal surgeons at one of the 10 eligible treatment centers in the United States deliver the gene therapy to the back of the eye by subretinal injection using a needle the size of an eyelash; about a week or so later, the patient undergoes the procedure in the other eye.

“Spark Therapeutics is thrilled patients continue to benefit from LUXTURNA (voretigene neparvovec-ryzl),” Giordano, Spark’s External and Product Communications Lead, said. “A gene therapy is a major milestone, not only for those of us at Spark, but also for the patient community and broader gene therapy field.”

The cost of the drug – $425,000 for each eye – initially caused anxiety among patient families, but Giordano had good news about insurance coverage.

“Payer coverage has exceeded expectations, and to our knowledge no treatment-eligible patient has been denied treatment due to their insurance coverage,” he said.

LUXTURNA also is being used beyond this country through license and supply agreements with Novartis, which has the rights to commercialize the drug in Europe and all other markets outside the United States. Spark manufactures and supplies the gene therapy to Novartis, according to Giordano.

Also, results from ongoing studies continue to support the drug’s safety profile and efficacy.

“In 2019, Spark presented four-year durability data from the LUXTURNA Phase 3 clinical trial,” Giordano said.

For privacy reasons, Spark Therapeutics cannot share patient results.

But we can – at least a couple of them because they came from patients and families sharing their stories with us.

For Hannah, ‘Hope Realized’

Hannah Reif, daughter of Amy and Chris Reif of Maple Glen, PA, underwent LUXTURNA gene therapy in July 2018. Dr. Albert M. Maguire, who is married to researcher Dr. Bennett, performed Hannah’s surgery at Children’s Hospital of Philadelphia (CHOP).

“We closely watched the clinical trials and the FDA approval process for seven years, starting when Hannah was diagnosed with LCA/RPE65 at just a few months of age,” Amy said. “Seven years of hope. 

“Two years out from Hannah’s surgery, I can say we feel grateful and fortunate that she was treated with LUXTURNA. No regrets. LUXTURNA was hope realized. It delivered what it promised.”

She said what that has meant for Hannah has been nothing short of life changing.

“It has given her more independence, which has been wonderful for her self-confidence. It has given her the ability to see what she couldn’t before.”

Since the surgery, Hannah’s vision in dim lighting and her visual acuity improved. She is now 9 and just finished third grade. 

Sometimes, her mom said, it’s the little things that are the most amazing.

“A year after the surgery, she was about to eat hot oatmeal and said, ‘Hey, I see steam. Hey, I can see that,’ ” Amy said.

“There are still things that pop up that she’s seen for the first time, like when she said, ‘Mom, did you know there’s a pattern on this toy?’ It’s fun to see her discovering.”

Amy said she and her family will be forever grateful to Dr. Bennett.

“There has been a lot of talk about heroes recently and Dr. Bennett is our hero. We are grateful for this groundbreaking treatment that she developed, that has been life-changing, not only for our daughter, but also for the sons and daughters and loved ones of so many others as well.”

‘His Vision Changed Everything’

Creed Pettit, one of the first recipients LUXTURNA, received the gene therapy at age 9 in March 2018. Dr. Audina M. Berracol  performed the surgery at Bascom Palmer Eye Institute in Miami, Fla.

His mom, Sarah St. Pierre Schroeder, told us that her now-11-year-old is doing amazing and only occasionally has issues with dim lights, “but nothing like before.”

Their days in Mount Dora, Fla., have changed in a major way.

“He still starts his day with his trusty smoothie and waffle, but after that, Creed wants to create new pranks (today was putting ice in the tub). He said it was nice and warm so I could soak my feet.”

Creed now loves to play board games – Trouble, Sorry, Battleship and Uno. 

“His vision has changed everything. He can manipulate small objects, he is using pointer fingers, and loves trying to roll his eyes in the mirror.”

Creed still likes to draw, and he loves riding and popping wheelies on his bike named Carlitos. He also likes to talk.

“Talking more is an understatement! Sunup to sundown, he is talking. He has also learned how fun it is to use his imagination, something he never did before. He creates awesome stories during this time.  He is so much more independent; I have to remind myself of that often.”

At first, she and her husband, Chad, could see that Creed’s vision improved some, but once he became confident about his gene replacement, they noticed him finding toys and games.

“He was suddenly enjoying things he didn’t before. He now expresses when he can’t see. Yesterday it rained all day, I kept waiting for him to tell me it was too dark inside, but he was fine. He just started doing staring contests. I love looking at his eyes during the contest.”

Sarah said she is incredibly grateful.

“Creed’s surgery is something we still thank God, St. Raphael, St. Lucy and Sister Miriam Teresa, for every night.” 

Like many kids across the country, Creed finished school at home because of the coronavirus pandemic. He graduated from fifth grade and thought because he finished school at home, he wouldn’t have to wear the graduation cap.

“But I was not going to let that slide,” his mom said. “I made one and took pictures.”

Anxiety, and a Friend to Call On

Throughout his journey, though, Creed felt anxious, something Sarah had learned that might happen when, before Creed’s surgery, she talked with Tami Morehouse, a LUXTURNA clinical trial participant at age 44.

Tami, a Sofia Sees Hope Ambassador, tries to calm fears and advises potential gene therapy patients and their parents that even though undergoing the surgery has the potential to do such good by improving vision, they should think about their expectations, especially with children.

“We are comfortable in our own zone; give us a little bit of change and it can throw us off,” Tami said.

Sarah understands. 

“He started to have a lot of anxiety. He had a hard time sleeping. I feel everything changed so fast that he was overwhelmed, but we have worked hard on getting past that.”

Sarah and her family are in a great place now. But after they were home from the hospital in Miami and settled into their routine, she said she became very emotional.

“All the tears I had held in for nine years started to come out. I felt I no longer had a purpose; I was so used to staying busy. I did not know who I was supposed to be.” 

She got some help and realized she still was needed because people need her help learning about and understanding this groundbreaking gene therapy.

“I still find myself shocked over how this has changed Creed’s life and so many other lives.”
