RS1-related retinoschisis gene therapy for vision improvement
This Phase 3 trial tests a gene therapy (ATSN-201) to improve or preserve vision in people with RS1-associated X-linked retinoschisis (XLRS), a genetic eye condition. You may qualify if you have a certain level of vision and specific eye “schisis” changes seen on a scan.

Lentiviral gene therapy for childhood cerebral X-ALD
This trial studies an experimental gene therapy given through infusion (IV) and into the spinal fluid (injection) for people with X-ALD affecting the brain. It aims to improve or slow down damage in the nervous system, and you must be able to do MRI scans and meet specific health and infection requirements.
Shenzhen, GuangdongAges 1–60 - NCT04064307Recruiting
Register people with myotubular or centronuclear myopathy
This study sets up a patient registry for people diagnosed with myotubular myopathy or centronuclear myopathy. Your information can help researchers better understand these conditions and plan future studies or treatments.
Newcastle upon Tyne, Tyne and WearAges Any age - NCT04980638RecruitingPhase 2
Check ER004 given in the womb for a genetic tooth-skin disorder
This Phase 2 study tests ER004 put into the amniotic fluid during pregnancy to treat male babies with X-linked hypohidrotic ectodermal dysplasia (XLHED). It also looks at effects in affected male relatives with the same gene change.
Los Angeles, CaliforniaAges 18 years+ - NCT05814952Recruiting
LX103 eye treatment for X-linked retinoschisis
This trial studies whether LX103 can improve vision and is safe for people with X-linked retinoschisis (XLRS) caused by RS1 gene changes. It focuses on a specific level of vision in the study eye and checks for medical conditions that could affect eye testing or safety.
ShanghaiAges 6 years+ - NCT05939232Recruiting
Registry for X-linked adrenal and brain fat disease
This study collects health information and test results from people with X-linked adrenoleukodystrophy (X-ALD) and some genetic carriers. It helps researchers better understand the condition and how it varies, which can guide future care and studies.

Common questions
- Are there clinical trials for x-linked?
- Yes. Clin2 currently lists 52 recruiting x-linked studies from the U.S. registry, each rewritten for real people, not researchers, so you can see what it’s testing and who it’s for.
- How do I know if I qualify for a x-linked trial?
- Each study lists its eligibility criteria — rules about age, diagnosis, and prior treatments. On every Clin2 trial page we explain these in words written for real people and offer a short, optional pre-screen for a fit read. The study team makes the final decision.
- Does it cost anything to join a x-linked trial?
- Using Clin2 is always free. Many trials cover the cost of the study treatment and related visits; some reimburse travel. The study team explains exactly what’s covered before you decide.
