Gene Therapy Consortium

Gene therapy is a promising line of investigation for rare diseases. However, gene therapy also requires significant financial investment, long timelines, and deep expertise across a variety of domains which makes it daunting to pursue for many diseases. Because gene therapy may be a viable path for creatine deficiency treatments, the ACD is pursuing how to best engage and speed up research in this area.

In the winter of 2019, our parent community raised an initial fund of $50,000 to be used towards gene therapy research efforts. With this support in mind, the ACD established the CCDS Gene Therapy Consortium in 2020 to foster concentrated efforts into gene therapy for creatine deficiencies.

As a first step, we brought together a group of outstanding researchers with deep expertise in gene therapy and/or creatine deficiencies to form the Gene Therapy Consortium. They include Dr. Jagdeep Valia, Dr. Andreas Schulze, Dr. Nicola Longo, Dr. Laura Baroncelli, Dr. Matt Stockler, Dr. Gerry Lipshutz, Dr. Olivier Braissant and Dr. Steven Grey. Several of these researchers have been engaged in gene therapy research in either CTD or GAMT and are sharing their expertise and knowledge with the entire consortium.

The mission of the consortium is to facilitate the timely sharing of information and development tools among labs that are pursuing gene therapies for creatine deficiencies. We believe that by building a collaborative environment and supporting shareable tools through grants we can shorten the timeline and effort required to find gene therapy solutions for creatine deficiencies. The consortium meets on a quarterly basis as a group to discuss the latest research and provide peer expertise. Sangeetha Iyer, ACD Scientific Advisor, and Laura Trutoiu, ACD Director of Research facilitate the scientific meetings and follow-up conversations while ensuring that the parent voice is represented.

July 2020 Update:

In February 2020, ACD held the first gene therapy consortium meeting to discuss progress on gene therapy approaches for CCDS and the outstanding problems faced by the field.

The first meeting shared information on the vector types, i.e. the viral delivery methods that are being developed to generate the gene therapies and the pros and cons of each method. This fostered a discussion around the outstanding questions in the field-

  1. What are the levels of creatine that need to be achieved in the brain and elsewhere for global correction? 
  2. How do cells and tissues regulate the intracellular concentrations of creatine?
  3. What approaches could be utilized to answer these questions?

Understanding these factors will aid in the development of a safe gene therapy for CTD. Given the shared metabolic pathway for creatine and GAMT, such findings could also be extended to GAMT gene therapy approaches. 

It was noteworthy that all researchers in the gene therapy consortium were discussing insights and data that were unpublished thus far. All members agreed that the goal of the consortium would be to share such data and insights to aid in the collective development of gene therapy for the field of CCDS. It would also serve as a forum to advance collaborative efforts between consortium members. At the end of the meeting, ACD discussed with each researcher the possibility of funding research efforts through the money raised from patient advocates and CCDS families. 

With the information learned through these conversations, ACD has created the Gene Therapy Advancement (GTA) Award. Each grant will be up to a limit of $10,000 and is proposed to be used towards capacity building, resource/tool creation, or fulfillment of experiment.  To apply for the GTA award, each researcher can submit a short proposal where the goals of the proposal and impact of the results will be outlined. Each proposal will be evaluated by the ACD board of directors with guidance from scientific researchers. 

 

Q2 GTA Award

In June, ACD made the decision to award the first GTA grant to Dr. Laura Baroncelli, Italy, to facilitate capacity building efforts for her lab, specifically focused on the incorporation of intrathecal viral delivery techniques in mice. Intrathecal administration is a route of administration for drugs via an injection into the spinal canal so that it reaches the cerebrospinal fluid (CSF) and is useful for drugs that need to reach the brain. With this award, Dr. Baroncelli’s lab will be able to test new viral vectors for expression and subsequent correction of defects in the brain. It’s worth noting that learning this technique will require skills from another consortium member, Dr. Steven Grey, who generously volunteered to share his expertise.
