Our concept Gene-based therapy

In this Pillar, we will design, develop and optimize a combination of existing and novel gene-based therapeutic strategies, aiming to translate these to IRD and AMD patients. The therapeutic strategies that will be developed here will be mainly applicable to IRD and AMD patients who demonstrate retinal integrity in order to ‘revive’ the cells that are still present yet not properly functioning. The enormous allelic heterogeneity of IRD can be considered a complicating factor for therapy development but also offers exciting opportunities for highly specific molecular interventions tailored to an individuals’ genetic defect, by correcting the root cause of disease. These intervention strategies lie at the DNA or RNA level, depending on the type of mutation underlying IRD. For AMD, similar innovative technologies will be employed to reduce the genetic risk of getting AMD, and to modulate the levels of genes whose expression is dysregulated in the pathologic pathways characteristic for this disease. Finally, since a precise spatiotemporal delivery of therapeutic molecules is instrumental for success, this Pillar will also be dedicated to the design and optimization of delivery strategies. Depending on the therapeutic molecules that have to be delivered, and the target cell(s) within the retina, either viral or non-viral vectors will be employed.

Our innovation

We will implement highly innovative strategies, such as antisense oligonucleotide (AON)-based allele-specific breakdown, PRIME editing, and inserting variants protective for AMD, that are entirely new for retinal diseases, while building on firmly established strategies (gene augmentation, AON-based splicing modulation). In addition, we aim to optimize the repertoire of suitable delivery vectors by comparing currently available to novel vector systems. Thus, we will be able to design and refine truly personalized, innovative and effective treatments for visually impaired individuals, precisely tailored at their genetic profile and disease characteristics.

Camiel Boon

About me

I am a clinician-scientist, working as an eye doctor and researcher. My research motto is: ‘From bedside to bench, and back’. The highlight of my career thus is without a doubt that I was able to perform some of the first-in-human gene therapy eye surgeries at Amsterdam UMC.

Your contribution to Lifelong VISION

As a doctor, the specific expertise that I bring to Lifelong VISION is a translational view, with an emphasis on novel gene therapy techniques (gene replacement, CRISPR-based techniques) in a multidisciplinary setting. In addition, my aim is to develop better insights into the most sensitive clinical endpoints to assess disease progression and treatment efficacy in patients. I am a team player, enjoying crosstalk and close collaboration between disciplines. This makes Lifelong VISION the perfect stimulating research environment for me and my research group.

I started at the Radboudumc in 2007. After my PhD (2010-2014) at Radboudumc, a post-doc at Rockefeller University (New York, USA, 2014-2016), I started my own research group ‘Blindness Genomics and Transcriptomics’ in 2016.

Contribution to Lifelong VISION

My expertise resides in the field of inherited retinal disease gene discovery. Using state of the art short and long reach sequencing approaches my team and I uncover new genetic causes underlying retinal disease.

About me

I am a PhD candidate at the Radboud UMC, driven by a deep curiosity about the human body, on both the cellular and the organ level, and by a passion to improve patients’ lives. With a bachelor’s in Biomedical Sciences at Leiden University and a master’s in Molecular Mechanisms of Disease at Radboud University, I am well-equipped to start groundbreaking research. During several internships, I have learnt a lot about immunology and infectious diseases. Now, as a PhD candidate, I am excited to enter the field of inherited retinal diseases and hopefully make a meaningful impact on health care.

Your contribution to Lifelong VISION

My project is under the supervision of prof. Rob Collin and Dr. Susanne Roosing. As a part of Pillar 1, we aim to identify and develop novel therapeutics for inherited retinal diseases, using molecular technologies at the level of nucleic acids. Potential therapies will be tested in iPSC-derived retinal organoids.
