Who runs the X-Linked Hypophosphatemia trials in the US, and what stage they are in
None of the 1 X-Linked Hypophosphatemia trial with a US site is in Phase 3, the last stage before a company can ask the FDA for approval. One more is an earlier Phase 1 or 2 test of safety and dosing. Companies run all of them, with none led by a university, hospital or government group. The most recently listed one first appeared on ClinicalTrials.gov on July 29, 2024.
X-Linked Hypophosphatemia trials in the US, state by state
None of the 1 X-Linked Hypophosphatemia trial with a US site lists children under 18 as eligible. A trial counts once in each state where it has an open site, and some trials accept both children and adults.
US hospitals running the most X-Linked Hypophosphatemia trials

Help getting to a X-Linked Hypophosphatemia trial far from home
Ask the study team whether the trial pays back travel, parking and hotel costs, because many sponsors do. The FDA's guidance on paying research volunteers says paying back these costs does not count as pressuring someone to join.
These nonprofits also help patients reach care, and each one sets its own rules.
- Mercy Medical Angels
- Pays for gas cards, ground rides and airline tickets anywhere in the US, and it lists clinical trials as a reason to travel. Household income at or below 300% of the federal poverty guidelines, and usually a trip of 50 miles or more each way.
- Air Charity Network
- Volunteer pilots in all 50 states fly patients for free in small private planes, and members also fly people taking part in clinical trials. You must be able to walk and sit upright for the flight, show financial need and have a backup plan if weather cancels it.
- Healthcare Hospitality Network
- Keeps a map of hospitality houses near hospitals, and most member houses charge little or nothing to patients and families. Each house sets its own rules, so check with the house near your study site.
Program details were checked on each program's website on October 24, 2026.
