Who runs the Common Variable Immunodeficiency trials in the US, and what stage they are in
None of the 8 Common Variable Immunodeficiency trials with a US site is in Phase 3, the last stage before a company can ask the FDA for approval. Earlier Phase 1 or 2 tests of safety and dosing make up 5 of them. One is a Phase 4 study of an already approved treatment. The remaining 2 have no drug phase, such as studies that follow people over time or test a device or a way of giving care. Universities, hospitals, foundations and government groups run all of them, with no company leading one. National Cancer Institute (NCI) runs the most, with 2. The most recently listed one first appeared on ClinicalTrials.gov on December 16, 2025.

Help getting to a Common Variable Immunodeficiency 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.
- Ronald McDonald House
- Gives families a room near the hospital while a child gets care, through 394 House programs around the world. Families of a sick child, with rules set by each local chapter.
- 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.
