In this Cell & Gene Therapy TIN interview as part of the Early Career Innovators series, recognising the amazing translational work being done by postdoc and non-tenured researchers within the UCL Therapeutic Innovation Networks (TINs), Dr Marion Mercier highlights her Cell & Gene Therapy TIN Pilot Data Fund awarded project, involving the validation of novel gene therapies for epilepsy.

What is the title of your project and what does it involve?

Human brain tissue is routinely excised during epilepsy surgery, and can, given the right conditions, be maintained alive in slice culture for extended periods of time. My project, entitled “Validating novel AAV gene therapies for epilepsy in human organotypic slices”, involves firstly to optimise human tissue slicing and culture protocols for the successful maintenance of this tissue, and secondly to establish efficient viral transfection methods in these human organotypic slices. The specific virus used encodes for a protein that suppresses neuronal excitability and as such is being developed as a gene therapy strategy for epilepsy. Thus, the project aims to establish a human tissue model in which to validate and screen this, and future, gene therapies for epilepsy developed within the DCEE.

What is the motivation behind your project/therapeutic?

Epilepsy affects 1% of the global population, and 30% of patients are pharmaco-resistant, with significant associated morbidity. Several novel gene therapies for epilepsy have recently been identified and developed within the DCEE, and offer real hope for these patients. However, while results from animal models have been promising, understanding how these genetic manipulations, and the adeno-associated viral vectors (AAVs) used to deliver them, will behave in the human brain still poses a significant challenge. Furthermore, the irreversible nature of gene therapy makes transitioning from animal models to human patients particularly risky. By establishing human organotypic slices to extend the viability of excised human brain tissue, and thereby enabling transfection with AAVs (which take 2-3 weeks to express), I aim to develop a human neuronal tissue model in which to screen and validate these novel gene therapies for epilepsy and thereby help to bridge this important translational gap.

Can you highlight any challenges have you experienced as an early career researcher in the cell and gene therapy/translational research space?

Obtaining funding for your own independent ideas and research is particularly challenging as an early career researcher, and is often impossible without considerable preliminary data. This makes getting started on new projects, and gaining the independence necessary to progress on to more senior, permanent positions, especially difficult. Furthermore, as an early career researcher working at the intersect between clinical and more basic science, I have found the complex translational research pathway quite challenging to navigate.

What do you hope to achieve in the 6 months duration of your project?

I have two main objectives for the 6 months duration of the project. The first is to establish good quality human organotypic slices that are viable for up to 3 weeks, and the second is to develop effective viral transfection methods in these slices. I will be transfecting the tissue with AAV-hCaMKII-EKC-GFP, a virus that aims to increase expression of an enhanced K+ channel (EKC) in human excitatory neurons, and which has shown promise as a gene therapy strategy in animal models of epilepsy. Thus, while optimising protocols for viral transfection of human organotypic slices, I hope to also start to collect clinically-relevant data pertaining to the safety of the viral transfection and the selectivity of the expression. I am currently in the first phase of the project and have already improved the human tissue slicing protocol and started to optimise the slice culture methods.

Why did you want to apply to the Cell & Gene Therapy TIN Pilot Data Fund?

In order to start this project, all I required was two specialised pieces of equipment and a little extra funding for consumables. The Cell and Gene Therapy TIN Pilot Data Fund is ideally suited for this, and therefore provides the perfect stepping stone for getting started and obtaining quality preliminary data with which to then apply for further funding. Furthermore, it has enabled me to progress my research in a more translational direction, and to learn more about the translational pathway and all of the steps involved in getting a therapy from the lab to the clinic. This will not only be an invaluable help in establishing and advancing this current project, but also in informing my future research plans.

We are currently in the process of determining our funding availability for the Cell & Gene Therapy TIN for 2021. Please join the Cell & Gene Therapy TIN and sign up to the TIN newsletter to keep updated. 

How did you find the process for the TIN Pilot Data Fund? What did you learn?

The application process was rewarding and a great learning experience. I attended the ACCELERATE coaching session on pitching projects, through which I learnt a great deal about how to communicate my ideas effectively, concisely and convincingly. Receiving this training prior to the interview made the final pitching exercise exciting rather than daunting and made it an overall positive experience through which I received a lot of constructive feedback. This has given me more confidence in my ideas and capabilities and pushed me to be more competitive and ambitious in driving my research forward.

About Dr Marion Mercier

Dr Marion Mercier a postdoctoral researcher in Prof. Dimitri Kullmann’s laboratory within the UCL Institute of Neurology’s Department of Clinical and Experimental Epilepsy (DCEE). After an undergraduate degree in Psychology at Reading University and a year as a technician working on drug discovery for epilepsy, Marion moved to Bristol to do her PhD in the laboratory of Prof. Graham Collingridge where she studied glutamate transmission and synaptic plasticity in the hippocampus.

Recently, she has begun to study human cortical function in resected human brain tissue, and is interested in establishing human neuronal models from this tissue in order to validate the gene therapy strategies for epilepsy currently being developed within the DCEE.

In this Cell & Gene Therapy TIN interview as part of the Early Career Innovators series, recognising the amazing translational work being done by postdoc and non-tenured researchers within the UCL Therapeutic Innovation Networks (TINs), Dr Ellie Crompton highlights her Cell & Gene Therapy TIN Pilot Data Fund awarded project, involving new therapies for rare disease Maple Syrup Urine Disease (MSUD). 

What is the title of your project and what does it involve?

My project is entitled “Development of novel therapies for Maple Syrup Urine Disease (MSUD)”. MSUD is a rare, paediatric, metabolic disease caused by mutations in three genes. When mutated, the body cannot produce a functional enzyme complex that is used to break down branched chain amino acids (BCAAs) in the liver. This leads to a build-up of these BCAAs and metabolic decompensation of the patient. In this project, we are attempting to treat the underlying disease pathology using a bioengineered novel therapy, developed at UCL, with the aim that this will lead to improved BCAA metabolism, provide neuroprotection and prolong survival.

What is the motivation behind your project/therapeutic?

Currently, MSUD patients are commonly treated with strict dietary management, or in some cases patients are offered a liver transplant to correct the underlying disease. Both of these approaches have major pitfalls. The low-protein diet needed to avoid build-up of BCAAs is often said to not be palatable and this leads to compliance issues in infants and children prescribed this diet. A lack of available donors also severely limits the possibility of liver transplant. By restoring metabolic function in MSUD patient cells, we have the potential to allow the body to produce the enzymes necessary to break down BCAAs and alleviate the need for sub-optimal diet management and transplant strategies. Furthermore, our therapy is unique because it will be relevant to all MSUD patients regardless of their specific genotype or phenotype. If successful and translated to the clinic, this has the potential to fulfil an unmet medical need.

Can you highlight any challenges have you experienced as an early career researcher in the cell and gene therapy/translational research space?

As a Research Fellow in my first post-doctoral position, I am beginning to navigate my way around the field in which I work. Before I started this post, I was unaware of the need to start generating ideas that could lead to fellowship applications at the very beginning of your post. The need to bring in funding of your own whilst only just starting your career can be daunting, especially when a majority of grant applications require you to have certain level of seniority to be eligible. There is some pressure that ECRs need to secure grant funding to progress their career, but this can be difficult when fresh out of a PhD, with one publication and no previous track record of successful grants.

Why did you want to apply to the Cell & Gene Therapy TIN Pilot Data Fund? How has it helped you?

The work proposed in this project is really exciting and is definitely worth exploring. I think there are some great advantages to the novel therapy approach we are researching, and without the TIN grant, this work may not have been possible. The TIN pilot fund has given me the opportunity to generate invaluable preliminary data that can support future, larger grants. There is the age-old dilemma of needing good preliminary data for large grant applications, but having no money to generate it. The TIN funding has allowed me to begin this process. I wanted to apply for this funding to kickstart my career in the cell and gene therapy field, allowing me to build my portfolio of work only a few months after finishing my PhD.

The Cell & Gene Therapy Therapeutic Innovation Network (TIN) are offering the opportunity to appear in a resource to showcase and promote the diversity/depth and breadth of expertise within the Cell & Gene Therapy space across UCL. Appearing here will raise your profile and visibility in the field of Cell & Gene Therapy, not only across UCL but with also with external academic and industrial partners leading to rewarding collaboration and funding opportunities.

How did you find the process for the TIN Pilot Data Fund? What did you learn?

Applying for the TIN Pilot Data Fund was a simple process with an application form consisting of only a couple of pages, rather than a large grant application with tens of pages. This made it feel far less intimidating. After being told I was shortlisted, the offer of a coaching session from ACCELERATE to improve the three-minute, 2-slide presentation that was requested was incredibly helpful. I learnt which elements of the project and application I should highlight, and which to prepare answers to questions, but not immediately bring up. The coach was very helpful and really useful experience for my career.

What do you hope to achieve in the 6 months duration of your project?

Within the 6-month duration of this project I hope to generate preliminary data that can elucidate whether a broadly applicable pan-genotype approach is more beneficial, and whether novel therapy is better than other therapies currently under development. The progress of my project has been slowed considerably due to Covid-19 and the challenges this has produced, but I am hopeful that we can generate a good package of data at the end, even if it is not entirely the same as that which was proposed.

In the next Small Molecules TIN interview as part of the Early Career Innovators series, acknowledging the amazing translational work being done by early career researchers within the UCL Therapeutic Innovation Networks (TINs), Benedikt Hölbling highlights his Small Molecules TIN Pilot Data Fund awarded project, “Enhancing Stathmin-2 protein levels in familial and sporadic ALS/FTD”.

What is the title of your project and what does it involve?

The title of my project is “Enhancing Stathmin-2 protein levels in familial and sporadic ALS/FTD”: Cellular loss of the protein Stathmin-2 is a common hallmark of Amyotrophic Lateral Sclerosis (ALS) and Frontotemporal Dementia (FTD), two devastating neurodegenerative diseases. We aim to identify ways to modulate Stathmin-2 protein levels in cells to improve neuronal health. For this aim, we developed a high throughput screen to identify small molecules that could be used as novel therapeutics for ALS/FTD treatment.

What is the motivation behind your project/therapeutic?

ALS and FTD are fatal neurodegenerative diseases with no effective treatment available yet.
ALS, also commonly known as motor neuron disease, occurs when specialized motor neurons in the brain and spinal cord perish. Every year approximately 1700 people in the UK are newly diagnosed with this disease, with a mortality rate of 50% within the first 2 years.

Approximately 16,000 patients in the UK live with FTD. This rare form of dementia causes symptoms such as changes to personality and/or difficulties with language.

The majority of therapeutics under development would require regular, invasive lumbar punctures to administer or focus on specific disease-causing genes. However, most ALS cases are sporadic (90%) without familial history of the disease. Further, the genetic causes are very diverse. A common characteristic that is shared among most familial and sporadic cases is the loss of cellular Stathmin-2 protein levels. It was shown that overexpression of Stathmin-2 improves neuronal health in cell cultures (Klim et al., 2019 and Melamed et al., 2019). Therefore, finding modulators of Stathmin-2 expression may enable treatment of a large number of patients with various ALS and FTD disease backgrounds rather than targeting specific disease-causing genes. In addition, an oral delivery of small molecules is non-invasive and easy to administer.

Why did you want to apply to the Small Molecules TIN Pilot Data Fund?

We have developed a high-throughput screen in close collaboration with the Alzheimer´s Research UK Drug Discovery Institute at UCL. The Small Molecules TIN Pilot Data Fund will now enable us to perform two pilot screens with this model. Thereby, we will further increase the accuracy and reliability of our assay for large-scale screens in the future.

Furthermore, I applied for my personal development: There are very limited opportunities to apply for funding as an Early Career Researcher. Therefore, I was highly excited to be able to apply for the Small Molecules TIN Pilot Data Fund. From the start of this project, I could improve many of my skills in the lab and outside.

How did you find the process for the TIN Pilot Data Fund? What did you learn?

It was very exciting! I was never involved in a grant application before, so everything was very new to me. During the process, I attended two ACCELERATE training workshops. In the first one, I learned how to write more precise whilst not too scientific for my written application. Especially as a non-native speaker, this also will be a great help for future applications. However, the pitch was the most exciting part of the process. Explaining the innovation and importance of your project in only 2 minutes is very challenging and the ACCELERATE workshop was extremely helpful to set the right focus.

What do you hope to achieve in the 6 months duration of your project?

In the next months, we will perform two pilot screens with different small molecule libraries. Thereby, we will hopefully identify helpful tool compounds. Further, this helps us to optimize and validate our assay before utilizing larger small-molecule libraries in the future.

What are your next steps from now?

The next step is to perform two pilot screens together with the ARUK Drug Discovery Institute at UCL. Once we identify promising molecules with the screen, we will closely characterize them to determine which one of them is the most promising candidate for a novel ALS/FTD therapy.
