Clinical Trials

The XLH Network, Inc. does not endorse or critique specific clinical trials, and does not counsel individual patients either for or against participation in any specific clinical trial. Prospective volunteers should always carefully review the clinical trial's informed consent documentation and protocol, and discuss the pros and cons of their participation with trusted advisers, including their health care providers and family members. The NIH website ( offers some good questions to consider while deciding whether to enroll in a clinical trial.
