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 (clinicaltrials.gov) offers some good questions to consider while deciding whether to enroll in a clinical trial.
Ultragenyx Online Survey
Ultragenyx Pharmaceutical, Inc. is sponsoring a research study to better understand how XLH impacts the lives of affected children and adults. The study consists of an online survey that asks questions about your experience with XLH, including how it was diagnosed, what symptoms and complications you (or your child) have experienced, how the disease has been managed and how these events affect your daily life. Anyone interested in participating should click here to learn more about the study.
Mobility, Gait and Range-of-Motion Analysis Studies
We are seeking 40-65 year old men and women with X-linked Hypophosphatemia (XLH) to participate in a research study at Quinnipiac University (Frank H. Netter School of Medicine, North Haven, CT). The purpose of this study is to learn more about the impact of XLH on the daily life and activities of adults with XLH. Using the information we learn from this study, we expect to gain a better understanding of the day-to-day challenges facing adults with XLH and, ultimately, hope to develop strategies that lessen the burden or even help overcome these challenges.

NIH Research Study
NIH Research Study: Open-label Dose-titration Study of the Tolerability and Efficacy of Cinacalcet to Treat Fibroblast Growth Factor 23 (FGF23)-mediated Hypophosphatemia
Principal Investigator: Dr. Rachel Gafni, MD
Sponsoring Institute: Craniofacial and Skeletal Diseases Branch, NIDCR, National Institutes of Health
The purpose of this study is to see how treatment with a drug called cinacalcet affects people with low blood phosphorus (hypophosphatemia) caused by hypophosphatemic rickets or tumor-induced osteomalacia. Studies have suggested that cinacalcet may decrease phosphorus loss by the kidneys in these disorders. If the cinacalcet works, the blood level of phosphorus may be higher. This could result in patients needing less phosphorus medication. It may also help the bones become stronger.
This study will help us figure out the best dose of cinacalcet and how many times a day it should be taken. Individuals who qualify for the study will take cinacalcet in addition to vitamin D and phosphorus. All study visits will be at the NIH Clinical Center in Bethesda, Maryland. There will be up to 3 inpatient visits and several outpatient clinic and lab visits. Once cinacalcet therapy is started, there will be 3 - 5 visits with a physician every 3 weeks over a 4- to 7-month period. During the NIH visits, participants will undergo several assessments, which may include a dental evaluation, blood tests, urine tests, x-rays, and questionnaires. Patients will be paid for participation in this study. You may be eligible if you are between 18 and 70 years of age and have been diagnosed with low blood phosphorus.
