TheRoadmap to a Cure

Three-Year Strategic Research Plan

If you love a child with Rett Syndrome, you want the answer to one all-consuming question: Will there be a cure? We are confident the answer is YES, and we have a solid plan to get us there. But we can’t do it alone. We will need the commitment and the support of Rett families in the US and around the world. We invite you to learn about our $33 million, three-year strategic research plan.

RSRT will not be satisfied with
subtle symptom improvement.
We want a cure.

TAKE ACTION

Cure

Funding needs $13,000,000

At the core of the plan are four cutting-edge priority approaches that are designed to cure Rett Syndrome by attacking the root cause of the disorder: MECP2. These approaches, which will be pursued in parallel, are applicable to any and all MECP2 mutations and deletions.

Gene Therapy

Gene therapy is the most advanced of our four curative approaches and is our lead program. The concept behind gene therapy is simple: delivery healthy copies of the MECP2 gene to compensate for the mutated ones. Over the past three years the results of our Gene Therapy Consortium have exceeded expectations. The magnitude of improvement in the mouse models of Rett is much greater than that of any drug in development and suggests that significant benefit may be achieved in people.

Our Roadmap goals are to begin the first ever gene therapy clinical trial in people and to support development of improved second-generation gene therapy programs.

Gene therapy consortium

A single gene therapy treatment should be a one-time fix

MECP2 Reactivation

Girls and women with Rett have a mutation in only one of their two copies of the MECP2 gene. Like all females, one of the two MECP2 copies is randomly inactivated. The mutated gene is active and making defective protein in approximately half of all cells in the body, while the healthy copy of the MECP2 gene in those cells is silenced. Reactivate the silent copy and theoretically Rett is cured.

There is a healthy copy of MECP2 in every cell, we don’t have to deliver it, it’s already there, we just have to find a way to wake it up.

RNA Editing

The possibility of editing RNA has profound therapeutic potential, but has remained largely theoretical. Focused investments by RSRT have already demonstrated the potential for correcting MECP2 mutations at the level of RNA. We are currently increasing our investment to aggressively pursue this therapeutic approach.

Goals during the next three years are to improve specificity and efficiency of editing RNA in the brain and to identify optimal delivery methods

Protein Replacement

We are collaborating with a biotech company that has developed a technology to deliver proteins to the brain. Alternative technologies are also being developed. We will monitor, evaluate and pursue worthy approaches.

Covering Every Base

Our four curative approaches intervene at all three stages of the “gene to protein” process. This multi-pronged strategy greatly increases our chances of success.

Treat

Funding needs $3,300,000

Although focused on CURE we will also monitor treatments that have the potential to improve quality of life.These approaches do not directly target the root cause of Rett, MECP2, and therefore cannot be considered cures. All current and past clinical trials for Rett fall into this category. We will monitor all treatment development programs and selectively invest in those most likely to significantly improve symptoms.

“By attracting the best scientists and clinicians, RSRT is in pole position to deliver on the pre-clinical work showing that Rett Syndrome will be a curable disorder.”

Enable

Funding needs $9,200,000

RSRT will play a vital role in creating the conditions that will enable the most impactful pharmaceutical and biotech industry investment in Rett research. Historically, approval of new drugs has been hampered by the absence of several key resources: 1) Lack of accurate, FDA-approved outcome measures for clinical trials, including devices that can accurately measure these outcomes, 2) The ability to identify the right patients for the right trials, and 3) Lack of human cells from patients to test new therapies in the lab.

The following projects will address these issues and drive industry investment in Rett research. They are designed to remove barriers of entry and lower risk, thereby shortening the timeline for drug development and facilitating the approval of novel therapeutics.

Outcome Measures &
Biomarkers Development

There are currently no FDA-approved outcome measures for use in Rett clinical trials. We have established a consortium of expert Rett physicians to develop outcome measures that are meaningful to patients and their families and that are acceptable to the FDA and other international regulatory agencies. These measures fall into two groups: regulatory-approvable outcome measures and biomarkers that predict or correlate with efficacy. Part of this effort will also include collecting information on Rett symptoms and the needs of individual patients in order to shorten clinical trial enrollment time.

Testing Therapies in Patient Cells

Because no animal model can completely duplicate the human disease it is important to verify results from animal studies using human cells. Today, technology exists to convert skin or blood cells collected from individuals with Rett into brain cells. These cells can be used to replicate results observed in animal models. Since brain cells can be generated from any individual with Rett, this technology also allows us to assess whether there are significant differences among individuals in response to a new therapy. We will build a bio-repository of these cells that can be freely accessed by academic and industry scientists.

Learn

Funding needs $4,500,000

Our strategic investments in basic science have led us to this promising new stage of research in which we can realistically pursue the curative approaches just described. We live in an exciting time: scientific advances are continuously providing insights that could open doors to new and better ways to treat your children. Therefore it is critical for RSRT to continue to LEARN by closely monitoring scientific breakthroughs and novel technologies that can be put to work to defeat Rett.

Maximizing the Impact of Your Support

Since RSRT’s founding, we’ve been committed to maintaining exceptionally low overhead expenses. This commitment will continue, with expenses for fundraising and administration less than 10% of the research plan budget. Here is how the $33 million plan will be allocated across the different paths:

The $41 million that we have strategically awarded to research to date has resulted in the knowledge, data, and partnerships that inform and guide this Roadmap to a Cure.

RSRT sets the research agenda by proactively identifying and monitoring promising therapeutic areas, seeking out scientific and industry partnerships and working closely with them to advance programs through the drug development pipeline.

The RSRT team is lean and fiercely focused on what matters most: healing our children as quickly as possible.
