An observational study in Neuromyelitis Optica, Neuromyelitis Optica Spectrum Disorder and Transverse Myelitis, sponsored by University of Texas Southwestern Medical Center. Active, not recruiting at 1 site in United States. Open to participants aged 6 Years and older, including healthy volunteers. Per ClinicalTrials.gov, last updated 2026-01-06.
Sponsored by University of Texas Southwestern Medical Center · Observational
This study seeks to determine the biologic causes of inflammation in patients with Transverse Myelitis (TM) Neuromyelitis Optica Spectrum Disorder (NMOSD) and related conditions. While patients will be treated according to decisions with their treating physician, this study will collect data and samples from patients prospectively to gain a better understanding of the disease. We are seeking to understand why some patients respond to medications, while others do not. We also seek to understand what happens biologically, preceding relapses. Gathering these data and samples will allow researchers to identify new ways of diagnosing and treating these diseases. Data and samples will be shared with researchers around the world to support collaborative efforts to treat these conditions.
This study seeks to determine the biologic causes of inflammation in patients with Neuromyelitis Optica (NMO), Transverse Myelitis (TM), optic neuritis (ON), related conditions and healthy controls.

Patients will agree to share medical records, complete questionnaires and donate samples on a timed basis.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
