About Clinical Studies for Rare Diseases
The development of an investigational treatment is divided into steps called ‘phases’. The investigational treatment generally passes through each phase successfully before it can continue on to the next.
|PHASE 1||PHASE 1/2 OR 2||PHASE 3|
|3-50 people||10-60 people||12-150 people|
|Usually healthy volunteers but can be people with the disease||People with the disease||People with the disease|
|Safety and how the body breaks down the study treatment||
Safety and effectiveness (the ability of a study treatment to produce a beneficial change)
|Long-term safety and effectiveness compared to current standard of care or a placebo (a sugar pill)|
Once the studies are complete, the study information along with other information on the drug is submitted to and reviewed by a government agency (e.g., the United States Food and Drug Administration, or FDA). If the data shows the study treatment is safe and effective, it may be approved for use by prescription.
Ultragenyx is evaluating investigational treatments in clinical studies in a number of rare diseases.
Rare Disease Organizations
Ultragenyx partners with several organizations across all rare diseases. These groups represent individual rare disease advocacy organizations to government. They contribute to research and fundraising efforts.
