We are working tirelessly to bring transformative therapies to patients.
Why Participate in a Clinical Trial?
By participating in a clinical trial, patients receive access to the newest treatments available while contributing to a better understanding of specific diseases and how best to treat them. Clinical trials are primarily conducted to help future patients by providing valuable information about the risks and benefits of investigational drug candidates. If you would like to learn more about the clinical trial process, you can access this information through the U.S. Food Administration website.
If you are considering participating in a clinical trial, you should speak with your doctor. If you are interested in learning more about our trials, diseases that we are pursuing, patient resources or gaining access to our product candidates, please visit our clinical studies overview page.
