NEW RESEARCH THANKS TO
THE ‘USHER ACTIE RIJNSBURG’ FRIENDS GROUP

Usher syndrome, characterized by sensorineural hearing loss and progressive Retinitis Pigmentosa (RP), presents a significant challenge for the medical community. With the most involved gene, USH2A, treatments for Retinitis Pigmentosa are becoming increasingly promising. The use of correctly chosen endpoints will prevent unnecessary failures of potentially effective treatment studies and accelerate the development of treatments.

Thanks to the years of unwavering enthusiasm and dedication of the ‘Usher Actie Rijnsburg’ group, Stichting Ushersyndroom can financially support an important study into the right biomarkers and endpoints.

Correlation between structure and function
In this study, led by Dr. Suzanne Yzer, ophthalmologist at Radboud University Medical Center in the Netherlands, researchers aim to examine the retinas of patients with Usher syndrome by combining existing ophthalmic examinations with newly developed imaging techniques. The combined information will provide a more detailed correlation between the structure and function of the retina, yielding essential data for a comprehensive analysis. This will enable the identification of the best biomarkers and endpoints for clinical trials for Usher syndrome patients. Biomarkers and endpoints that will aid in treatment trials (clinical trials), ensuring that outcomes and information are indisputable and provide evidence of treatment effectiveness.

“Correctly chosen endpoints help prevent the unnecessary failure of a potentially groundbreaking treatment study.”
Dr. Suzanne Yzer, Ophthalmologist at Radboud University Medical Center

Delay
A poorly designed study or wrongly chosen biomarker or endpoints can lead to years of delay before the therapy becomes available to patients. This is not only a significant disadvantage for the specific treatment but will also deter investors from supporting new studies.

Incorrect endpoints
The failure of a treatment study does not necessarily mean that the investigated therapeutic treatment is ineffective. Studies may fail because of inaccurately chosen inclusion criteria or endpoints. In August 2022, ProQR’s clinical trial was halted for this reason. The endpoints for another clinical trial (for LCA) were not accurately defined, resulting in them not being met. Investors withdrew, leading to insufficient funding to continue the clinical trial for USH2A exon 13.
The clinical trial has since been restarted; Laboratoires Théa (Théa) has taken over the study.

Existing and new imaging tools
With the first clinical trials on the horizon, it is crucial to select the right biomarkers and endpoints. Radboudumc has conducted a large natural history study in a large group of patients with mutations in USH2 genes, the CRUSH study, and the RUSH2a study. Results are expected in the fall of 2024. Since the start of these studies, progress has been made with existing and newly developed imaging tools, such as “Adaptive Optics” and the “High Magnification Module” lens.

Increasing opportunities
The current study focuses on identifying the most reliable biomarkers and endpoints for future therapeutic studies in Usher syndrome type 2. By identifying better endpoints, the chances of demonstrating treatment effectiveness will be increased, helping to advance the development of treatments. This will also make it more attractive to accelerate the implementation of new clinical studies, such as gene replacement therapy for Usher syndrome, including minigenes for USH2A and USH2C, and exon excision therapy.

This will ultimately benefit all patients with Usher syndrome. The goal is to achieve successful treatment and administer the drug or therapeutic treatment in the earlier stages of the disease, thus preventing severe loss of photoreceptors. The findings will be published in scientific journals and will contribute to the advancement of gene-specific therapies for retinal diseases.

Thanks to the Usher Action Rijnsburg and the co-financing from the Vaillantfonds and the Aanmoedigingsfonds van de Koninklijke Facultatieve the Stichtig Ushersyndroom can financially support this research.This project is budgeted at € 226.000,- and will last for three years.

Friends group of Liesbeth
‘Usher Actie Rijnsburg’ is a friends group that takes action for their friend Liesbeth and other people with Usher syndrome. They organize various activities and an annual event to raise as much money as possible.

‘Moon Rocket Grant’ awarded to two groundbreaking projects

At this moment, there is no treatment yet for Usher Syndrome, a disorder that globally 400.000 people suffer from. In order to find a treatment that can stop, slow down or even reverse the process of becoming both deaf and blind, more knowledge and research into Usher Syndrome are needed.

Therefore Stichting Ushersyndroom (The Dutch Usher Syndrome Foundation) presents the ‘Moon Rocket Grant’: € 200.000, – for research into Usher Syndrome with a maximum of € 100.000, – for each study.

The Moon Rocket Grant
Stichting Ushersyndroom has launched the Moon Rocket Grant: a large pot of money for pioneering research into (a treatment for) Usher Syndrome. The objective of the Moon Rocket Grant from the Stichting Ushersyndroom is to effectuate a moonshot formulated by us: ‘A treatment for Usher Syndrome in 2025!’ This moonshot includes all types and subtypes of Usher Syndrome.

The study proposals must fit in with one of the four core values of the ‘Moon Rocket Grant’: Treatment, Knowledge, Diagnostics and Impact.
Every study (fundamental, translational or clinical) must lead to a treatment option, more knowledge and understanding, better diagnostics and an increase of the impact for every type of Usher Syndrome.

The Medical Advisory Council extensively tested and assessed all submitted study proposals. After this first assessment there was a second round: an on-line presentation with a short interview, after which the final selection for the award was made.

The Moon Rocket Grant goes to …..

Stichting Ushersyndroom announces with pleasure that two projects are eligible for the Moon-Rocket Grant 2022.

Prof Mariya Moosajee (UCL Institute of Ophthalmology, London, UK), will receive € 100.000, – for the project:

Prof Mariya Moosajee

“Large Gene Augmentation with non-viral episomal vectors for Usher syndrome”

Use of non-viral plasmid vectors for Usher Syndrome
It is well-known that the AAV (adeno-viral virus) vector is used for gene therapy, but this vector has a limit to the size of the gene. Most Usher genes are way too large for being packed into an AAV vector. When applying gene therapy to the retina of patients using the AAV vector, sometimes thinning of the retina (also called atrophy) can develop. Therefore alternative ‘packaging’ vectors are to be found for future gene therapies for Usher Syndrome.

Prof Mariya Moosajee has in cooperation with Dr Richard Harbottle (DKFZ German Cancer Research Centre, Heidelberg) developed a DNA plasmid (USH2A-S/MAR-vector) which can hold the full-length USH2A-DNA.
The DNA plasmid has been tested in a zebrafish model as well as in patient cells taken from a skin biopsy.

Prof Mariya Moosajee will use the ‘Moon-Rocket Grant’ to test the system of DNA plasmid in an already existing rabbit model for USH2A.
If the application of this alternative gene replacement strategy turns out to be successful, this will have a great impact for all inherited retinal diseases. After this study, it may be possible to start a phase 1 clinical trial for patients and it also may offer solutions for other large Usher genes. Gene therapy making use of DNA plasmid may have additional advantages; application (several times) with a limited immune response. Prof Mariya Moosajee hopes this approach will be safer and can avoid some of the complications that are seen in the current viral gene therapy. This project will at least take 2 years and has been budgeted at over € 200.000. Moorfields Eye Charity and Cure Usher will also be contributing to this project. With the contribution of the ‘Moon Rocket Grant’ from the Stichting Ushersyndroom the budget has been covered and the study can start.

The second project to be financed by the Moon Rocket Grant is the study of Monte Westerfield (Neuroscience, university of Oregon) and Erwin van Wijk (Radboud University Medical Center, Nijmegen, the Netherlands) entitled:

Prof. Monte Westerfield and Dr. Jennifer Phillips

“Exon-skipping as a future treatment for USH1F associated retinal disease” 

In this collaborative study Monte Westerfield of the University of Oregon and Erwin van Wijk of the Radboud UMC will develop and evaluate a treatment for Usher syndrome type 1F-related retinal disease based on the exon skipping methodology.

About 20.000 people worldwide lose their eyesight as a consequence of PCDH15 mutations. This condition is named USH1F.
The PCDH15 gene codes for the protocadherin 15 protein (PCDH15 protein) and is essential for normal eyesight and hearing. The PCDH15 protein contains multiple predicted extracellular cadherin (EC) domains. Many USH1F patients have mutations in the region encoding the EC domains number 6 (EC6) and 7 (EC7), resulting in a non-functional or even absent PCDH15 protein.

The ultimate goal of the researchers is to develop a treatment that halts the progression of PCDH15-associated visual dysfunction. For this, they will adopt the principle of “exon skipping” and develop a “genetic patch” that will instruct the light-sensitive cells inside the eye to skip the region of the PCDH15 gene that codes for the EC6 and EC7 domains. In this way a somewhat shorter but hopefully still functional PCDH15 protein is produced, specifically lacking the EC6 and EC7 domains.

A pilot study exploring the therapeutic potential of “exon skipping” for USH1F was conducted some years ago. In this study the researchers targeted another domain in the protein, but this did not result in a restored function of the PCDH15 protein. With the knowledge gained in the past few years the researchers can now better predict whether or not the remaining protein after exon skipping will be functional. Based on these improved prediction tools they now opt for “skipping” the region encoding EC domains 6 and 7.
In previous studies of both Monte Westerfield and Erwin van Wijk it was shown that zebrafish are suitable animal models for this study. To obtain functional proof for the proposed concept of skipping the EC6-EC7 encoding region of PCDH15, the researchers aim to remove this part of the PCDH15 gene from the zebrafish genome and analyze whether these ‘treated’ zebrafish will have a better eyesight than the untreated mutant zebrafish with USH1F mutations.

This research project was budgeted at € 100.000, – for a period of 24 months.

The objective of Stichting Ushersyndroom is to finance scientific research that is to lead to a treatment that will show down, stop of even reverse the deterioration of hearing and eyesight. Apart from this, the foundation also (financially) supports the improvement of the quality of life, the growth of knowledge and information about Usher Syndrome and to enhance the contact between fellow-sufferers.

Looking back at 2022

LEES HET ARTIKEL IN HET NEDERLANDS

One year ago the Usher Syndrome Foundation announced its reaching the milestone of 1 million euro of donations. A huge and almost magical amount of money! Thanks to the many donations, actions and events we reached this amount six years after the first start of the campaigns. This has enabled us to finance a number of scientific studies.

The special milestone of 1 million gave everyone wings. And this was shown in the year 2022!


We collected almost half a million euro of donations in one year! Thanks to all contributors and thanks to you!

Thanks to the many donations and gifts, we can finance several new (inter)national research projects.
The first 2 new studies that we will fund have already been announced at the end of December 2022. We will announce the two funded studies from the Moon Rocket Grant and another new research project in early 2023.

The start in 2022
The year started with a change in the board and expansion of the board: Diede Heijkoop took over the function of secretary from Annouk van Nunen. Johan Driessen joined the board as a member and was given the fund-raising portfolio. After a short familiarisation period the board started with the development of a Strategic Plan. Where are we now and where do we want to go? And how do we expect to get there?
We have the moonshot “A treatment for Usher Syndrome in 2025!”, but we are looking further ahead. The Stichting Ushersyndroom wants a ‘moon landing’ in 2030. After a year of interviews, away days, on-line meetings and many discussions, we are now busy developing a Strategic Plan. We will present this plan early in the year 2023.

A visit to the researchers
The board received a progress report with respect to all ongoing studies (co-)financed by the foundation. Because of the renewal of the board and also in view of the major financial contribution that the foundation makes to scientific research, the board went to visit the researchers in the Radboudumc. The board was given a presentation and a tour for each study. Sometimes big steps are made in one year, but sometimes there also are setbacks to cope with.

Mini genes 2a: this study was patented. Researchers are talking about further cooperation with companies. Which company wants to take part in the pre-clinical phase in order to lift the study to the next level? Read more ….

Mini genes 2c: the sticking together of small coding ‘pieces’ of the gene to make a mini-gene-2c was disappointing at first, but after a few months delay and several attempts, the researcher succeeded in this! At the same time, another researcher was developing an innovative tool with which predictions can be made with the help of the computer whether a protein will or will not be functional. This made clear that the mini-genes-2c required minor adjustment. These adjustments are presently being made and will subsequently be tested. Read more …

CRUSH-study: Most CRUSH participants will be called for the very last time in the coming year. The study is heavy and burdensome for the participants. However, the analyses and results are of great value for the researchers and all people suffering from Usher Syndrome. The results will be of help in future treatments. In order to hearten the participants of the CRUSH study, they all received a small present from the foundation. The presents are handed out to the participants with each visit. Read more …

Sleep study: Many interview were held during the first year of this study. This showed that there is a clear difference between the control group and the group of people suffering from Usher Syndrome. These people had much more sleeping problems, especially with respect to sleeping on. What exactly is going on? For answering this question zebrafishes are used as animal models. We hope to know more next year. Read more …

USHIII: The ‘USHIII Initiative’ spent a large part of the past year on going through all procedures for an application with the FDA in order to be able to start the trial. Preparations are being made. The commitment of Dr Ronald Pennings and Dr Suzanne Yzer is mainly focused on the natural development study and based on data from the past that are already available in existing medical files.

Global Usher Awareness Day 2022
Every year on the third Saturday of September, we celebrate ‘Global Usher Awareness Day’. On this day, which falls on the same day as the autumn equinox, the sun is directly above the equator and the day and the night have the same length. Following the autumn equinox, there will be less light every day; days get shorter and nights get longer.

Usher? So what!
Especially for the Global Usher Awareness Day the Usher Syndrome Foundation published a video podcast series with Joyce de Ruiter and Femke Krijger, in which they talk about their ‘USH-life’.

Joyce is ambassador of the Usher Syndrome Foundation, author and professional speaker. She published, among others, the book ‘Niet horen, niet zien, niet zwijgen’ (not hear, not see and not keep silent).

Reggeborgh supports Stichting Ushersyndroom en Radboudumc
Reggeborgh supports the 4-year study ‘Development of Exon Excision Therapy’ by Dr. Erwin van Wijk and dr. Erik de Vrieze at Radboudumc. In this research, the aim is to permanently remove specific exons in which patients have hereditary mutations from the DNA of the photoreceptors in the retina and/or the hair cells of the inner ear using the CRISPR/Cas9 gene editing technique. The aim of this strategy is, with a single treatment, to stop the deterioration of vision (and in time hopefully also of hearing) in larger groups of patients who have mutations in these exons of the USH2A gene.
An incredibly important and hopeful research!
We would like to thank Reggeborgh for making this research possible! Read more ….

Run, cycle, walk, collect returnable bottles and crotchet oven cloths
This year was filled with wonderful actions and initiatives! For example, over 100 people joined in the Run4Usher during the Zandvoort Circuit Run. Tim Schroeder made his gigantic cycling trip to Alicante and will make a gigantic cycling trip again in 2023. Wilte Jager cycled the 11-city race in 24 hours with his tandem buddy. The first edition of NL wandelt voor Usher (The Dutch walking for Usher) turned out to be a huge success. The Run4Usher during the 7 Hills Run was a feast of unity and the gallery of the many bottle deposit actions is growing steadily. On WhyDonate we see a number of other wonderful actions that were organised for the Usher Syndrome Foundation in the past year: Billie for Usher, Crosse for Josse, Tennis tournament and clinic HOT in Nieuw and also Team Lente took up a sportive challenge.

Really great actions were organised for the foundation on the action platform Support & Donate as well: The A-team took action for the Usher Syndrome Foundation and Tim van der Avoird did his most heavy sportive challenge ever.

There also were runs during the Marathon of Rotterdam  and the Wateringse Veldloopfestijn and in Breda, the 40 kilometres of the Canal Run were run by the famous ’40 of Breda’.

Tears as a source of information?

LEES ARTIKEL IN HET NEDERLANDS

Stichting Ushersyndroom and Usher Syndrome Ireland

finance research into USH1b

Can tears provide information that may be important for improving diagnostics and monitoring in future treatments of USH1b patients? In the pilot study “Investigating the exosome content as a novel marker for Usher syndrome 1b” Dr. Irene Vázquez Domínguez, who is working at the Radboudumc (Nijmegen, the Netherlands), will investigate tears. By doing this, she wants to assess whether there is any indications on tears that can be employed as a source of information and therefore may contribute to not only increase the current knowledge of the disease but also to allow better prediction of the development of Usher Syndrome type 1b.

This study will be mainly financed by the Usher Syndrome Foundation and partially co-financed by Usher Syndrome Ireland. If this study produces any positive results, the study of tears may lead to new strategies in USH research.

Tears
Tears are human body fluids. Tears are rich of proteins, lipoproteins and exosomes. Exosomes are small bladders which contain a wide range of molecules inside like RNA molecules. Thanks to that, exosomes are important for the communication between cells. In addition, they can be isolated from tears, which allow the study of their content.
As tears can be collected in a non-invasive way (without entering the body) from patients, they allow for easy and patient-friendly isolation of exosomes.

New biomarker for research
Biomarkers are measurable indicators that may indicate that someone is ill, predict how serious the illness will be or show whether a treatment is effective or not.

By making use of tears, the researcher Dr. Irene Vázquez Domínguez wants to find out whether biomarkers can be found that may be used to improve the diagnostics and to better predict the development of Usher Syndrome type 1b. In the long term, point-of-care tests could be developed on the basis of these biomarkers. Point-of-care tests offer care professionals the possibility to start, monitor or adjust a future development.

The MYO7A geneWe know that more than 10 genes are involved in Usher Syndrome.
This new study is focused on one of these genes, being the MYO7A gene. This gene is responsible for the production of a specific protein: Myosin, which keeps the photoreceptors (the rods and cones) of the retina alive.

Some children having mutations in the MYO7A gene do not develop retinitis pigmentosa in their childhood and puberty beside their hereditary deafness. Here we speak of non-syndromic deafness 

How can this be explained and/or predicted? The answer to this question may lead to better diagnostics. Sometimes it is really difficult for the parents to cope with the uncertainty whether or not their child will develop retinitis pigmentosa (RP).

Increasing the present knowledge about the MYO7A gene is necessary for finding new biomarkers that can be used for making the diagnosis and for predicting the development. At the same time, this knowledge can also be used in monitoring after a treatment.

Isolation of exosomes
Usher Syndrome falls within the group of Retinal Dystrophy diseases (RDs). The deterioration of the eyesight is caused by the dying of retinal cells, such as the light-sensitive photoreceptors and/or the retinal pigment epithelium (RPE).
Within the retina RPE cells are responsible for the majority of the production of exosomes. Previous studies indicated that tears may be rich of RPE exosomes.

The goal of the study is to isolate exosomes from tears as well as from RPE cells. Then, the content of both will be studied. First, the control group will be compared with the material from USH1b patients. Then the information from tear derived exosomes and RPE derived exosomes will be also compared to assess if, as it was suggested before, they provide the same information. If this turns out to be successful, this study will show that exosomes can be used as a means to develop new strategies in USH research.
Finally, this study will also show whether tears can be a source for research. This would help to find an easy and patient-friendly way to isolate exosomes.

This one year study was budgeted at  € 75.000, -.
Stichting Ushersyndroom (Dutch Usher syndrome Foundation) will finance this study with co-financing from Usher Syndrome Ireland.

Ivonne Bressers has appointed a knight of the Order of Oranje-Nassau.

LEES ARTIKEL IN HET NEDERLANDS

Mayor Ahmed Marcouch and Ivonne Bressers

King Willem-Alexander has appointed Ivonne Bressers (57) a knight of the Order of Oranje-Nassau. As president of the Dutch Usher syndrome Foundation and the driving force behind it, she is of inestimable value to the Usher patient group. Mayor Marcouch presented the award during the “lintjesregen” at the City Hall in Arnhem.

Ivonne Bressers has Usher syndrome. Most people with this very rare disorder are born hearing impaired or deaf and experience progressive sight and hearing loss. There are 400,000 patients worldwide, including 1,000 in the Netherlands who suffer from Usher syndrome. There is currently no treatment to stop the process of becoming deaf and blind. Ivonne’s deepest wish is that in 2025 there will be a treatment for every Usher syndrome patient.

Ambitious volunteer
From 2009 to 2015, Ivonne volunteered tirelessly and unpaid for the interests of the deafblind patient group. She participates as a volunteer in various working groups of the Eye Association OOG & OOR and makes great strides. With her project group, she managed to ensure that the second cochlear implant (an implanted hearing prosthesis) for deafblind people is fully reimbursed by health insurers. She also initiated the establishment of a national expertise center for patients with Usher syndrome within the Radboudumc. Nowadays, these patients can come here with their specific care needs.

Usher syndrome Foundation
In 2015 Ivonne starts in the campaign team of the Dutch Usher syndrome Foundation and joins as general board member in 2016. In 2019, she is appointed president of the foundation. A task she performs with enthusiasm, dedication and vigor.

From its inception until now, Ivonne, together with the efforts of volunteers for the Foundation, has managed to raise more than 1.1 million euros. The funds received are used to finance very promising scientific research, both at home and abroad, into an effective treatment for people with Usher syndrome.

The Royal Decoration is an extra stimulus for Ivonne to keep working on fulfilling her deepest wish: “in 2025 Ushersyndrome will be treatable for everyone”.

Run4Usher Zandvoort breaks all records!

LEES ARTIKEL IN HET NEDERLANDS

On the 27th of March, the Run4Usher team joined almost 12.000 other runners at the start of the Zandvoort Circuit Run. This beautiful spring day set the scene for one of the first major running events of the year. The Ushers Syndrome Foundation was chosen by Rotary Zandvoort as the official charity for this edition of the Zandvoort Circuit Run. Not only adults appeared at the start; for the young participants there was also a special Kids Run. The large team of Run4Usher broke all records on this wonderful day and collected the fantastic amount of € 85.427,- !

Pole Position
From Pole Position, the 185 participants of Run4Usher started the 13th edition of this spectacular running event.  The program consisted of various courses: the 10 English Mile (16.1 km), 12 km and 4 km (One Lap) and for the youngest participants there was the special Kids Circuit Run and the Wheelers and Racerunner Race. Also Carol Brill and Debs Heffernan from Usher Syndrome Ireland had been specially flown in for a one-lap track over the circuit.

In the special tent of Run4Usher at the Paddock there was the opportunity to meet each other and share the solidarity. After the Kids Circuit Run, the young participants were treated to various activities led by a large group of volunteers, there was candy floss, face painting and costumes as well as go-kart races at the Paddock.

Rijsterbij
The rapper Rijsterbij (Martijn Rijsenbrij) gave a benefit concert, selling his CDs and donating the proceeds to Stichting Ushersyndroom. Martijn Rijsenbrij sings Dutch hip-hop with solid beats. “It’s getting dark, all the lights are going out, but I’m not going to wait for the day it gets dark, to that thought I say thunder”. Martijn has the eye disease Retinitis Pigmentosa, just like all people with Usher syndrome.

All records broken
The participation and presence of the Run4Usher team did not go unnoticed and generated a lot of attention for Ushersyndrome during the event and in the media.

The proceeds for the Ushersyndrome Foundation are a record: the runners and their supporters, the volunteers who collected at the event and the additional proceeds from LeChampion and Rotary Zandvoort together raised € 85.327,- !

A long haul
For the project group, the organisation has also been a challenging time. The team that organised this edition of Run4Usher consisted of ‘Ushers’ Machteld Cossee and Carin de Bruin and ‘Usher parents’ Daan Wijsbek, Esmé Ter Stege and Liesbeth Kenters. Machteld: “I remember that in mid 2019 the first contact was made with the Rotary Club and Le Champion. We were going to watch and gain experience at Stichting Hartekind, which had been chosen as the Charity for that year, but unfortunately the pandemic threw a spanner in the works.”
Despite this, the project group continued to make plans and recorded a promo with John Williams, a Dutch celebrity. Because you never know!
Unfortunately, the 2021 edition of the Zandvoort Circuit Run was also cancelled due to corona.

Until the end of 2021, event organisation Le Champion cautiously gave the go-ahead.
“We had to switch gears for a moment and suddenly we were back in business. It took a lot of Zoom meetings and group apps to get everything right,” say parents Daan and Esmé. “Various interviews, sending out newsletters and having to arrange all the practical matters at the last minute, it was simply top-class sport! according to Carin. The ever-calm Liesbeth thinks it has been a matter of long breath. “We did it, and we did it well”. Fortunately, the project group was able to count on the support and assistance of a huge group of volunteers for the practical help.

Record proceeds
Thanks to sponsorships from runners, the sale of merchandise and volunteers who collected during the event, they managed to raise a staggering € 65.427,- !
On 11 April last, the members of the project group received a cheque from the Rotary Zandvoort and event organisation Le Champion.
This brings the total record revenue of € 85.327,- !

Thanks to the financial support of “Stichting ter verbetering van het lot der Blinden” for the incurred expenses, the entire proceeds of Run4Usher Zandvoort Circuit Run can benefit scientific research into and treatment of Usher, in order to stop the process of becoming deaf and blind. In this way, the dot on the horizon for people with Usher syndrome is coming ever closer.

Here you can see all the photos of the Run4Usher edition Zandvoort Circuit. With many thanks to photographer Sanne ter Horst.

Moon-Rocket Grant

Usher Syndrome Foundation Grant Call:
The Moon-Rocket Grant

The use of the word ‘Ushers’ for people with Usher syndrome is meant with a wink and refers to the meaning of the English word ‘Ushers’. People with Usher syndrome are the messengers of an important story or message.

The ‘Ushers’ tell what they need, what kind of help they need, what they find important and how they experience their life with Usher syndrome.

Currently, there is no treatment available for 400.000 ‘Ushers’ in the world. What is needed for the ‘Ushers’ is more knowledge and research into the Usher Syndrome. That is why Stichting Ushersyndroom [Dutch Usher Syndrome Foundation] awards the Moon-Rocked Grant: € 100,000 for research into Usher Syndrome.

The Moon-Rocket Grant
The goal of the Moon-Rocket Grant of the Usher Syndrome Foundation is to realize our formulated moonshot: “a cure for Usher in 2025!”.

The Moon-Rocket Grant is intended to financially support research into Usher Syndrome (any form or subtype).
All research proposals submitted must fit into one of the four core values ​​the Usher Syndrome Foundation has defined by:

  • Treatment
  • Understanding
  • Diagnostics
  • Impact

The Moon-Rocket Grant will award a maximum of €100,000 per research. If there are several eligible projects, more projects can be funded. A maximum of € 200,000 is available for financing.

What has Stichting Ushersyndroom [Dutch Usher syndrome Foundation] done with it?

We provide an overview and a glimpse into the future.

Mini genes USH2A
In the ‘mini genes’ project, the USH2A gene is artificially made smaller by taking specific parts of the gene and sticking these together (= minigene). This suddenly makes it possible to insert these minigenes into the current vectors for use in genetic therapy.
In this project the therapeutic effect of shortened USH2A protein variants will be tested in the zebrafish model.
The Stichting Ushersyndroom finances this study in 2016.

CRUSH study
The expertise centre for Usher Syndrome in Radboudumc started in 2019 a natural development study into Usher Syndrome, de CRUSH study.
This is a very important step in the research into a treatment for Usher Syndrome, because this study may substantially shorten the running time for trials. Stichting Ushersyndroom finances this five-year study.

Mini genes USH2C

In 2019, the Usher Syndrome Foundation funded the new research into Minigenes for USH2c. USH2c is caused by mutations in the USH2c gene (ADGRV1), and these errors in the gene lead to a progressive form of hereditary deafblindness. However, this gene is very large, so researchers want to try to make an artificially shortened version of the ADGRV1 gene. These mini-genes will be small enough to fit into a ‘viral vector’, but at the same time they must also remain functional.

Knowledge portal Usher syndrome

The Usher Syndrome knowledge portal is made available by Stichting Ushersyndroom.
A portal that has been developed for and by people with Usher syndrome in which they have bundled all their knowledge and information as experience experts and ‘Usher experts’.

Sleeping research
Are patients suffering from Usher Syndrome so tired because of the huge efforts made in connection with their poor hearing and eyesight or is something else going on? Researchers in the Radboudumc try to find an answers to this question. There are indications that perhaps there is more going on, a genetic cause.
In summer of 2021, the research into ‘The recognition of sleeping problems with patients with the USH2A gene’ stared. Stichting Ushersyndroom will finance a large part of this study.

Database USHIII

This year in 2021, the North-American foundation Usher III Initiative has taken preliminary steps towards collecting the information necessary to establish the first comprehensive global USH3 patient database. This resource will be critical to the design of future clinical trials and will significantly advance knowledge of the disease and its impact on patients.
Stichting Ushersyndroom has committed to making a contribution to support this effort.

Extra large vectors on mini retinas

Stichting Ushersyndroom is funding the majority of the new research “Genetic drugs preventing blindness due to loss of USH2A function” which has recently started. The research team led by Jan Wijnholds, who works at the Leiden University Medical Center (LUMC), will test two treatment methods on ‘mini-retinas’ made from human stem cells. The researchers want to determine if the light sensitive cells in the mini-retinas can be activated by the light-sensitive cells after administration of gene therapy.

The dot om the horizon

The mission of the Stichting Ushersyndroom is: “In 2025, Usher Syndrome will be treatable!” This is the all-encompassing goal, the “moonshot”, from which everything else is derived. This is why Stichting Ushersyndroom is here.

  • At the beginning of 2022, Stichting Ushersyndroom will send out a call: The Moon Rocket Grant. Researchers worldwide can submit an application for a grant that contributes to the mission ofStichting Ushersyndroom: “Usher Syndrome will be treatable by 2025!”.
  • A patient brochure is in the works and will be released in early 2022. It will be available online and offline.
  • In 2022 we will start with the first webinar. This is accessible to everyone who is committed to the mission of the Stichting Ushersyndroom. A new webinar with a different speaker every quarter.
  • Of course we also want to send out a new call: Rocket Fuel Grant. And the desire to be able to subsidize even more research projects that can lead to a solution for all people with Usher syndrome.

We are well on our way to the dot on the horizon! However, a lot of money is still needed. Can we count on your support again in the coming years?
