Leading the Fight to treatand cure Tay-Sachs, Canavan and related diseases
Developing a cure or treatment is a long, complicated and expensive process. This page will give you a basic understanding of the process. The NTSAD Scientific Advisory Committee closely monitors the scientific field and alerts NTSAD Families of important breakthroughs and developments.
Before scientists can attempt to treat disease they must understand the exact cause of the disease. How are cells damaged by the missing
enzyme? What are the biochemical pathways leading to disease? Basic research is often called â€œthe how does that work?â€ stage.
The next step is to take the basic understanding of the disease and try to intervene to slow, stop or reverse the symptoms. Often these studies start in a culture dish but eventually almost always result in animal model studies. Sandhoff mice are the most commonly used Tay-Sachs and Sandhoff animal model. Both mouse and rat models are commonly used to study Canavan disease. Affected mice are given potential treatments and closely monitored for improvements. If the mice show positive results, studies in larger animals such as cats and sheep are done because their brains are closer in size to humans.
After a potential therapy has been thoroughly demonstrated to alleviate disease in the animal models the regulatory phase of preclinical developments begins. Clinical trials must be reviewed and allowed to proceed by the Food and Drug Administration (FDA). This can be a lengthy and complicated process in itself. The steps in FDA clinical trial approval include:
In addition to FDA review of the clinical trial IND, the researchers must also receive approval from the Institutional Review Board (IRB) of all clinical trials sites.Â Also review and public discussion of the clinical trial protocol by the NIH Recombinant DNA Advisory Committee (RAC) may be necessary.
Clinical trials are typically done in three phases. However, when looking at treatments for very rare diseases like Tay-Sachs and other related diseases, the phases are often modified and blended together. Phase I typically looks at safety, Phase II looks at efficacy and safety, and Phase III verifies the treatment is safe and effective in a larger number of clinical trial subjects.Â Comprehensive natural history studies and clear biomarkers are vital to clinical trials to measure the efficacy of the treatment. The FDA approval of the productÂ is necessary before the therapy is commercially available.
