Myopathy Clinical Trial

Official title: WiTNNess: An International Natural History Study of Autosomal Recessive TNNT1 Myopathy

Status Recruiting

Clinical Trial Summary

WiTNNess is designed to accurately document the natural course and variation of muscle disease caused by pathogenic changes of the TNNT1 gene. The primary aim of the study is to specify meaningful outcome measures for future clinical trials. WiTNNess is open to children and adults worldwide. Participants can choose to include their information once (cross-sectional cohort) or every few months (prospective cohort).

Clinical Trial Description

WiTNNess is an observational study that includes prospective and cross-sectional arms, both of which include people diagnosed with autosomal recessive TNNT1-associated muscle disease, commonly described as a form of infantile-onset (NEM5A) or childhood-onset (NEM5B) nemaline rod myopathy. The study's primary objective is to establish the nature and time course of disease outcomes under current treatment, so that these can later be compared to outcomes achieved with novel disease-modifying therapies (i.e., interventional trials).

Participants from all over the world are welcome to enroll in either arm of the WiTNNess study. Following appropriate consent, those in the prospective arm are followed long-term. Recurring assessments are performed at the participant's home, the Clinic for Special Children, or a partnering clinical site, depending on the individual's particular circumstances. Basic assessments include vital signs, a physical exam, documentation of motor milestones, growth measurements, and blood chemistry values. Participant's may also undergo non-invasive ultrasound of the heart (echocardiogram) and one or more chest radiographs.

Participants in the cross-sectional arm are contacted once after consent. Members of the WiTNNess study team partner with healthcare providers and family members to capture pertinent medical history, physical exam findings, growth metrics, and motor milestones at the time of contact. ;
