Study summary

The objective of this study is to test a set of clinical outcome measures longitudinally in a cohort of OPMD patients to identify ones that show quantifiable change over time as the disease progresses. The investigators' goal is to delineate the natural history of OPMD.

Read the detailed description

OPMD patients will undergo a screening evaluation and testing to confirm the participants carry the OPMD mutation. Subjects fulfilling the inclusion/exclusion criteria will be enrolled and followed prospectively at regular intervals to determine the natural history of this disease. Measures of muscle function and swallowing will be made at baseline and at follow-up visits to measure natural clinical progression.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on May 27, 2022, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
