Ustalenie biomarkerów i klinicznych punktów końcowych w dystrofii miotonicznej typu 1 (END-DM1)
Building on previous work of the Myotonic Dystrophy Clinical Research Network (DMCRN), the present study seeks to overcome insufficient data on natural history; lack of reliable biomarkers; and incomplete characterization and limited biological understanding of the phenotypic heterogeneity of Myotonic Dystrophy 1 by examining strategies to improve the reliability by making further refinements in our sample collection and analysis procedures by developing strategies for managing patient heterogeneity going forward.

Szczegółowy opis
Approximately 700 adult participants (18 to 70 years old, inclusive) with DM1 will be enrolled at 15 centers (up to 70 patients will be recruited at each site). No treatment will be administered as part of this study. Participants will receive standard of care as determined by the investigators. Study visits occur at baseline/0 months, 12 months, and 24 months. Few restrictions are placed on participation in the study because the investigators aim to capture the full spectrum of disease severity.
Muscle biopsy sub-study: Studies of splicing biomarkers in muscle biopsy samples will be conducted on a subset of 95 participants. These participants will have an additional study visit at 3 months.
Longitudinal muscle biopsy sub-study: Up to 30 individuals who have had a prior muscle biopsy as part of a DMCRN study will be asked to undergo another biopsy greater than 24 months after the prior biopsy. These participants will have an additional ad hoc biopsy visit.
COVID-19 sub-study: To evaluate severity of illness and response to COVID-19 vaccination in DM1 patients compared to corresponding data available about the general population, END-DM1 study participants will be asked to complete a one-time survey about COVID-19 experiences. A subset of those participants' blood samples will be analyzed to understand immunoglobulin response to infection and vaccination in DM1 patients.
Actigraphy sub-study: To assess daily physical activity in individuals with DM1 and evaluate physical activity changes over a 12-24 month period related to disease progression, a subset of participants will be asked to wear a small, wireless activity monitor while performing functional assessments described in the main study. Those participants will be asked to wear the activity monitor for 7 days following their research visit. Those participants will be asked to complete additional questionnaires.
Handheld Dynamometry sub-study: To evaluate additional muscle strength methods, a subset of participants will be asked to complete additional strength testing using either the MEDup or MicroFET handheld dynamometry device on the same day as their END-DM1 main study visit. Those participants will be asked to return to the clinic for a second visit within 10 days of the END-DM1 study visit to repeat the handheld dynamometry assessments and complete additional strength measures.

Badana populacja
DM1 has a prevalence rate of approximately 1 per 2,300. There are no expected gender differences. Both men and women will be selected for this study.
Children with DM1 are not included in this project because the pathophysiological basis of congenital and childhood DM1 appears to be mechanistically distinct.
Opis
Inclusion criteria:
- Age 18 to 70 (inclusive)
- Competent to provide informed consent
- Clinical diagnosis of DM1 based on research criteria1 or positive genetic test
- Comment: The clinical research criteria require myotonia, muscle weakness in a characteristic distribution, and history of similar findings in a first degree relative. Genetic testing confirmed the diagnosis of DM1 in > 99% of individuals who satisfied these criteria.2
Exclusion criteria:
- Symptomatic renal or liver disease, uncontrolled diabetes or thyroid disorder, or active malignancy other than skin cancer.
- Current alcohol or substance abuse
- Concurrent enrollment in clinical trial for DM1, or participation in trial within 6 months of entry.
- Concurrent pregnancy or planned pregnancy during the course of the study.
- Concurrent medical condition that would, in the opinion of the investigator or clinical evaluator, compromise performance on study measures.
- Note: non-ambulatory participants are not excluded, but are limited to <15% of enrollment.
Inclusion criteria for participants in the muscle biopsy sub-study:
• Of the 95 patients undergoing the tibialis anterior muscle biopsy, at least half will have at least moderate weakness of ankle dorsiflexion, defined as MRC score ≤ 4+. This is in order to obtain a muscle tissue sample in a person more severely affected with myotonic dystrophy. Approximately 10 patients at each site will undergo the muscle biopsy.
Exclusion criteria for 95 participants in the muscle biopsy sub-study:
- Known CTG repeat expansion size less than 100 repeats, unless there are clear cut signs of limb weakness and muscle wasting. This is in order to obtain a muscle tissue sample in a person more severely affected with myotonic dystrophy.
- Use of anticoagulant such as warfarin or a direct oral anticoagulant (e.g. dabigatran) due to the increased risk of bleeding.
- Use of aspirin or non-steroidal anti-inflammatory agents should be discontinued 3 days prior to the biopsy procedure, if possible.
- Platelet count <50,000 (if known) due to the increased risk of bleeding.
- History of a bleeding disorder due to the increased risk of bleeding.
- Advanced wasting of tibialis anterior (TA) muscle that precludes needle muscle biopsy in order to ensure that a sample taken would be of muscle and not just fat and fascia.
- Previous muscle biopsy of either TA in order to provide muscle tissue samples of non-biopsied muscles.
