The Muscular Dystrophy Association’s neuroMuscular ObserVational Research Data Hub (MOVR): Design, Methods, and Initial Observations

Study population

Fig. 1

The MOVR Data Hub uses a multi-system approach for data collection, processing, and analysis. (Step 1) MDA Care Centers complete a Site Feasibility Questionnaire. Once approved by the MDA MOVR team, a Site Participation Agreement is negotiated and signed. The MDA MOVR team then provides ongoing support to MOVR Sites, including assisting with the IRB submission process, training sites how to enter data into the eCRFs, and providing answers to questions and concerns. Once training is complete, the MOVR Site begins enrolling and entering data for participants. (Step 2) Data entered in the eCRFs are extracted and transformed into a specified data format (raw vs CDISC). Data is then de-identified and stored as a limited dataset. IQVIA provides a secure PHI data environment and is responsible for data processing and quality control, standardization, and exporting. (Step 3) Researchers submit requests to access MOVR Data. Once approved, the limited dataset is customized to include only the requested data (i.e., only the indication(s) requested). The dataset is then delivered to the researcher and an active collaboration is established between the researcher and MDA MOVR team. For participating MOVR Sites, a custom visualization and reporting platform created in partnership with DNAnexus is provided for principal investigator and study staff to access and analyze data acquired by the site. Researchers may also request access to the VRP to view the aggregate dataset.

Seven indications under the MDA disease umbrella were selected to participate in the initial launch of MOVR – ALS, BMD, DMD, SMA, limb girdle muscular dystrophies (LGMDs), facioscapulohumeral muscular dystrophy (FSHD), and Pompe disease. These indications were selected by considering the availability of (1) approved therapies or multiple experimental therapies in development, (2) recommended standards of care and/or extensive input from researchers and clinicians within the MDA network, and (3) existing identification and standardization of data important for clinical trials. Individuals clinically diagnosed with one of the included indications who receive care at a participating Care Center (designated as a MOVR Site) are eligible to participate in MOVR. There are no exclusion criteria nor is a confirmed genetic diagnosis required. Individuals and/or their legal guardians sign an IRB-approved written informed consent and/or assent as appropriate. It should be noted that MOVR Sites are not required to enroll participants in all seven indications. Data from the USNDR were also migrated into MOVR and USNDR participants were invited to continue contributing data in MOVR under a new consent.

MOVR site selection & training

MOVR Sites represent a subset of MDA Care Centers who have elected to activate the MOVR Study Protocol. MDA Care Centers are specialized, multidisciplinary neuromuscular clinics funded by MDA to conduct patient visits on a regular basis (i.e., weekly, monthly).

The MDA MOVR team works collaboratively with the director of interested centers to evaluate the feasibility of participating in the MOVR Study Protocol. The MDA MOVR team then works with the center to negotiate a site contract and to receive IRB approval (from either their institutional or a central IRB) for the MOVR Study Protocol. Site onboarding by the MDA MOVR team includes training on the goals of MOVR, the International Conference on Harmonization and Good Clinical Practice regulations for observational studies, and the consent, data collection and data entry processes. Training calls are provided to new clinical research staff as needed while quarterly calls are held with each site to address questions and concerns about data entry and other MOVR-related activities. A MOVR-specific email address is monitored daily by the MDA MOVR team as a communication platform between quarterly calls.

Data Elements and Structure

There are four electronic case report forms (eCRFs) used to input data into MOVR: diagnosis, demographics, encounter, and discontinuation. The demographics and discontinuation forms are the same for each disease indication while the diagnosis and encounter forms are unique to each indication in order to capture the disease-specific diagnostic journey and progression. Each eCRF was developed by MDA’s scientific team and a registry-focused working group made up of experts in each disease area to ensure they aligned with site capabilities and current standards of care, while also reflecting research priorities. Continued review and improvement of these eCRFs is led by the current MOVR Research Advisory Committee (RAC).

The core data elements that are captured across all seven disease indications are listed in Table 1. The demographics eCRF captures disease type, enrollment date, gender, DOB, race and ethnicity, insurance, education, and employment. The diagnosis eCRF captures the date and age at diagnosis, symptom onset, genetic testing results, family history, first symptoms of disease, and clinical sub-diagnosis (i.e., LGMD2i, FSHD1, SMA Type I, etc.). The encounter eCRF captures longitudinal data on disease progression, including the encounter date, height and weight, clinical trial participation, surgical history, hospitalizations, functional measures, pulmonary and assistive devices, and multidisciplinary care referrals. Finally, the discontinuation eCRF captures the cause and date for discontinuation, and if the cause was due to the participant becoming deceased, additional details including cause and date of death are captured. In addition to these core data elements, there are additional data elements that are specific to certain indications (Table 2). For example, muscle biopsy information is captured for DMD, BMD, and LGMD but not for the other indications, while method of diagnosis (i.e., newborn screening, clinical presentation of symptoms, etc.) are captured for Pompe disease and SMA but not for the other indications. Each eCRF contains specific data fields that are marked as required and must be filled out for the form to be completed.

Data collection

The eCRFs are housed on a web-based portal hosted by IQVIA’s Registry Platform (IRP). Before beginning the study, the PI at a MOVR Site completes a Delegation of Authority log, which documents which individuals are responsible for data entry. Typically, data entry is completed by a research coordinator and/or a research nurse. Clinic study staff at a MOVR Site complete the eCRFs using data available from the participant’s electronic health record (EHR). MOVR Sites also have the capability of using EHR integration and/or batch data entry to auto-populate the eCRFs, but at time of publication, no sites have elected to use this method. The diagnosis, demographics and encounter eCRFs are completed at the initial study enrollment visit. Additional encounter eCRFs are completed at each subsequent visit. The discontinuation eCRF is only completed if the participant withdraws from the study, is lost to follow-up for two consecutive years, or becomes deceased.

Data quality control and processing

MOVR leverages IRP’s data quality control systems to ensure data completeness and accuracy across all MOVR Sites. Specifically, the eCRFs harbor several types of in-line data validations to reduce the entry of erroneous or implausible values. Three different levels of validation alerts indicate the severity of the problem and the action that is required to resolve the problem. For some data fields, previously entered values are highlighted to alert clinic study staff to potential errors. Extensive site training and quarterly calls are performed to discuss data entry, the quality of data being entered, and data completeness.

Data security and privacy

In accordance with applicable federal and state laws, MOVR (through the IRP) uses industry technology standards to implement administrative, physical, and technical safeguards to protect the accessibility, confidentiality, and integrity of protected health information (PHI) and any other confidential data. Specifically, MOVR is compliant with the Health Insurance Portability and Accountability Act (HIPAA) of 1996 and its implementation requirements for PHI as well as the FDA 21 Code of Federal Regulations Part 11 standards, which governs the proper use of electronic records and electronic signatures. The IRP undergoes annual independent HIPAA risk assessments [11] and an International Organization for Standardization 27001 certification process [12].

Participant privacy is ensured by user access controls that are actively monitored on a quarterly basis. Only authorized personnel at a MOVR Site have access to the fully identified data collected from participants at their site. Personnel from one site are not able to view identifiable data from participants enrolled at another site. A limited aggregate dataset for MDA and its third party service providers is de-identified following the guidelines defined in the Privacy Regulations issued under the HIPAA Privacy Rule [13]. For external data requesters, including academic and non-academic researchers and clinicians, a de-identification solution was identified in partnership with Privacy Analytics, an IQVIA Company, through the use of a HIPAA Expert Determination analysis [14], ensuring the highest utility of data while protecting the privacy of participants.

Data availability and governance

The overarching purpose of MOVR is to provide clinic-entered data to researchers and clinicians. A Data Governance Policy defines (1) MDA’s roles and responsibilities, (2) authorized and non-authorized use of data, (3) prohibited use of data, (4) data ownership, (5) publication guidelines, and (5) applicable fees. The Data Governance Policy must be read and agreed to before requesting access to MOVR Data and the Data Access, Use and Distribution Agreement must be signed prior to MOVR Data being delivered.

MOVR Data may be requested by any person located in the United States or abroad for an authorized use as described in the Data Governance Policy, including representatives from MOVR Sites, academia, industry, government, or nonprofit organizations. Data requests follow a formal review process to ensure that requested data is available within MOVR and that the proposed project design and analyses will produce meaningful scientific findings. Researchers must ensure that MOVR Data is stored securely using software that is compliant with current laws and regulations and is kept up-to-date. MOVR Sites and other selected researchers can also conduct analyses and visualize MOVR Data in a custom Visualization and Reporting Platform (VRP) hosted by DNAnexus. A description of the MOVR VRP is provided below (see “MOVR Visualization and Reporting Platform”). Finally, MOVR Data can be transformed into the Clinical Data Interchange Standards Consortium (CDISC) standard format [15] if requested. The MOVR RAC reviews any requests that fall outside of authorized and non-authorized uses and is responsible for making the final decision as to whether access to data will be granted.

MOVR visualization and reporting platform

The MOVR VRP enables MOVR Sites to visualize, organize, analyze, and report on their site-specific data and, if requested using the steps described above, the de-identified aggregate data. Approved researchers may also access MOVR Data via the VRP. Researchers can easily filter the MOVR dataset by any data field and save these filtered datasets as cohorts, which can be shared within research groups. Researchers are able to perform additional analyses by creating JupyterLab environments backed by Spark clusters to directly query MOVR Data and create data frames within a Python or R environment. Custom workflows and apps can also be created to perform routine analytics as MOVR Data is updated. To ensure the successful use of the MOVR VRP, new users can enroll in virtual live demos and have access to the MDA Community Project Portal, which includes newsletters, training guides and videos, FAQs, and a direct support link to DNAnexus, who hosts and manages the VRP.

Initial data analysis

MOVR Data were aggregated in May 2022 for preparation of this manuscript. Custom scripts using Python 3.10.0 and the NumPy 1.21.4 [16] and Pandas 1.3.4 [17, 18] libraries were written to generate the datasets used to perform the below analyses. The Matplotlib [19] and Seaborn [20] libraries were used to generate the graphical representations derived from these datasets.

Participant enrollment was determined by counting those participants who had a demographics, diagnosis, and at least one encounter eCRF. An index was created for these participants and used in all analyses so that only those participants who met this criterion were included. Two sub-indices were created to distinguish those participants who are enrolled in MOVR versus those whose data were migrated from USNDR (also referred to as ‘Legacy’).

The genetic confirmation data field is completed by selecting one of five categories with the exception of ALS, which has an additional ‘Other’ category. For this analysis, the number of participants within each category was counted and totaled for each indication.

For the sex assigned at birth and the ethnicity analyses, the number of participants in each category for the respective data field was counted and totaled for each indication. For the race and insurance type data fields, multiple categories can be selected. For participants with multiple categories selected, a new category (either ‘Multi-Racial’ or ‘Mixed Sources’ category, respectively) was assigned and then each category was counted and totaled for each indication. For all analyses, missing data fields and data fields containing ‘Not Reported’ or ‘Unknown’ were combined into a single category entitled ‘Unknown’.

The age at diagnosis data field was used to calculate the mean, median, the lower quartile (Q1), and the upper quartile (Q3). The interquartile range (IQR) was then calculated and used to identify outliers. Boxplots were created to visualize these data for each indication.

Longitudinal data availability was determined using three different measures: (1) the total number of encounters for each participant, (2) the time between a participant’s first encounter and their most recent encounter, and (3) the time between consecutive encounters. For the first measure, the number of encounters per participant was calculated and then assigned to one of five bins. The total number of participants assigned to a bin was then counted and totaled for each indication. For the second measure, the number of months between a participant’s first and most recent encounter was calculated and then assigned to one of six bins. The number of participants assigned to a bin was then counted and totaled for each indication. Finally, for the third measure, the number of months between each consecutive encounter for a participant was calculated and then assigned to one of six bins. The number of encounters within each bin was then counted and totaled for each indication. The average number of months between the first and most recent encounter as well as the average number of months between consecutive encounters were also calculated for each indication. Note, for the second and third measure of longitudinal data availability, participants who only had one encounter were not included in these two analyses.

Form completeness was introduced when MOVR was launched and did not exist in the USNDR dataset. Therefore, only those forms submitted for participants enrolled in the MOVR Study Protocol were used to assess form completeness. The number of eCRFs marked as ‘Complete’ or as ‘Incomplete’ were counted and totaled for each of the four eCRFs across the seven indications.

MOVR sites have actively enrolled participants across 7 NMDs

Most rare disease registries are powered by patients and their families who provide patient reported outcomes (PROs). Conversely, MOVR leverages the MDA Care Center network which is comprised of over 150 care centers and 300 NMDs across the United States to gather clinic-entered data. MOVR has onboarded 50 sites across 31 states (Fig. 2A). These sites were classified as adult only (n = 9), pediatric only (n = 16), ALS only (n = 4), adult and pediatric (n = 11), and adult and ALS (n = 10) Care Centers. Thirty-four MOVR Sites use the central IRB while 16 sites use their local/institutional IRB. The combined USNDR and MOVR data hub has 3,880 participants living with: ALS (n = 1,787), DMD (n = 1,107), SMA (n = 544), BMD (n = 237), LGMD (n = 109), FSHD (n = 80), and Pompe (n = 16) (Fig. 2B). Of these participants, 1,957 were enrolled directly into MOVR since 2019, while data from 1,923 participants were migrated from the USNDR (Fig. 2B). A total of 209 participants are no longer actively participating in MOVR (Fig. 2C) due to a combination of death (n = 187; 89%), withdrawal of consent (n = 6; 3%) or lost to follow-up (n = 16; 8%). The majority of participants who are no longer contributing data were those with ALS (n = 181; 87%) who became deceased (Fig. 2B). Taken together, the MOVR data hub has the capacity to collect and analyze data from numerous care centers and thousands of enrolled participants.

The total number of participants for ALS, DMD, SMA, BMD, LGMD, FSHD, and Pompe is 1,787, 1,107, 544, 237, 109, 80, and 16 respectively. Note that LGMD, FSHD, and Pompe were not collected in the USNDR dataset. (B) Participants who were no longer contributing data due to death, lost to follow up, or withdrawing consent. The number of participants no longer contributing data into MOVR was 209 (n = 194 ALS, n = 6 DMD, n = 2 SMA, n = 2 BMD, n = 3 LGMD, n = 1 FSHD, and n = 1 Pompe).

Rigorous eCRF requirements have resulted in a greater than 90% completion rate for MOVR only data

USNDR data entry protocols did not include in-line validations nor form completion guidelines. To improve data quality, MOVR implemented over 250 required fields across the eCRFs that must be completed, meaning over 75% of the main questions (excludes dependencies and sub-questions) must be answered. For MOVR only data demographic eCRFs were found to be 96% completed (Fig. 3A), diagnosis eCRF were 95% completed (Fig. 3B), and encounter eCRF were 87% completed, with the majority of the incomplete forms for ALS participants (Fig. 3C). Finally, 100% of the discontinuation eCRFs were completed (Fig. 3D). Combined, this means that 91% of all MOVR eCRFs were marked complete. The implementation of required fields has created a core dataset for each participant in MOVR, allowing a complete understanding of participant demographics, diagnostic journey, and disease progression across all MOVR sites.

The majority of MOVR participants have a confirmed laboratory genetic diagnosis

Neuromuscular diseases are difficult to genetically diagnose. Participation in MOVR does not require a genetically confirmed diagnosis nor does the MOVR Study Protocol implement a standardized set of diagnostic criteria that must be met. Rather, a participant’s diagnosis is dependent upon the expertise of the clinicians at the participating care centers. Excluding participants with ALS, 88% of MOVR participants have a confirmed laboratory diagnosis (Fig. 4).

Fig. 4

The majority of MOVR participants have a confirmed laboratory genetic diagnosis. Six of the 7 indications in MOVR are caused by a genetic mutation with the exception of ALS. Ninety percent of participants with DMD or SMA had a laboratory confirmed genetic diagnosis while 81% of participants with BMD, 71% with FSHD, 86% with LGMD, and 94% of those with Pompe disease have a laboratory confirmed genetic diagnosis. These percentages increase when including those participants who have an affected family member. For ALS, only 3% of participants of a confirmed laboratory diagnosis.

MOVR is comprised of participants of varying sexes and insurance backgrounds but does not fully reflect the racial and ethnic diversity of the United States Population

Demographic analyses performed on MOVR participants identified a nearly equal distribution of persons assigned male or female at birth with ALS (n = 1,030 M, n = 757 F), SMA (n = 262 M, n = 282 F), LGMD (n = 57 M, n = 52 F), FSHD (n = 40 M, n = 40 F), and Pompe (n = 8 M, n = 8 F) (Fig. 5A). Most participants with DMD and BMD were male (n = 1,097 and n = 236, respectively) while 7 participants with DMD were female and 3 were unknown (Fig. 5A). For BMD, only 1 participant was marked as unknown (Fig. 5A). The type of insurance for participants is variable across the seven indications. For DMD, SMA, and BMD, Medicaid is the most common insurance type with 41, 35, and 34% of participants, respectively, having Medicaid as their only insurance (Fig. 5B). For participants with ALS and Pompe, Medicare is the most common insurance type with 44 and 38% of participants, respectively, having Medicare as their only insurance (Fig. 5B). Medicare and Medicaid together comprise most of the insurances with 44% of all MOVR participants having either Medicare or Medicaid. Only 23% of MOVR participants have private insurance while 1% of participants have no insurance/self-pay (Fig. 5B). Both race (Fig. 5C) and ethnicity (Fig. 5D) were analyzed for each indication. The majority of participants identify as White (77% Fig. 5C). Race was unknown for 11% of participants (Fig. 5C). Ethnically, participants identify as Non-Hispanic or Latino (71%) or Hispanic or Latino (13%; Fig. 5D). Ethnicity was unknown for 15% of participants (Fig. 5D).

The age at diagnosis of MOVR participants is variable within each of the 7 indications

As shown in Fig. 6, age at diagnosis is variable across participants for each indication with several indications having multiple outliers. The mean age±standard deviation at diagnosis was 61.8±11.6 years for ALS (Fig. 6B), 5.0±3.1 years for DMD (Fig. 6C), 3.8±8.0 years for SMA (Fig. 6D), 10.3±10.2 years for BMD (Fig. 6E), 30.9±21.0 years for LGMD (Fig. 6F), 35.6±21.6 years for FSHD (Fig. 6G), and 36.7±25.4 years for Pompe (Fig. 6H). For those indications with multiple subclinical diagnoses/classifications, variability for age at diagnosis was reduced (data not shown).

MOVR has the capacity for longitudinal data collection across disease progression through clinical encounters

Longitudinal data availability was assessed using three different metrics. The first metric assessed was the number of encounters per MOVR participant (Fig. 7). Fifty-seven percent of participants had 1 to 2 encounters captured in MOVR while 23 percent had 3 to 4 encounters. Twenty percent of participants had 5 or more encounters. The mean number of encounters per participant was 3.2 for ALS, 3.3 for DMD, 2.9 for SMA, 2.7 for BMD, 1.9 for LGMD, 1.7 for FSHD, and 1.8 for Pompe. The average number of months between the first and most recent encounter ranges from 13.7 months to 26.5 months. Some participants (27%) had data collected across 26 or more months (Table 3). The average number of months between consecutive encounters ranges from 3.9 months to 9.1 months (Table 3), and 50% of these encounters took place within 5 or less months of each other. Taken together, these data provide MOVR with the capacity for capturing disease progression at routine clinical visits at multi-disciplinary NMD clinics.

Quantity

Since its inception in 2019 through the cut-off date for this publication, the MOVR Data Hub has collected data from 1,957 participants across seven indications from 50 sites, for a total of 3,880 participants when combined with legacy USNDR data. MDA’s goal is to extend MOVR to the majority of its 150 Care Centers, which collectively see over 60,000 individuals annually for regular care and participation in trials, and to add additional indications. This growth to date and potential for scale places MOVR in a prime position to the meet the data needs of investigators and drug developers. Even though the COVID-19 pandemic has disrupted clinical visits, MOVR continued to see growth as a direct result of enhancements such as the ability to consent participants remotely.

To increase the number of participants and the longitudinal data available in MOVR, the MDA MOVR team is working with sites to develop strategies that ease the burden of manual data entry on site staff. Currently, EHR integration is an available resource offered to participating MOVR Sites, but it requires collaboration between each site’s Information Technology department and IQVIA. Feedback received from sites so far suggests that manual data entry is preferred due to limited resources and conflicting priorities, although a few newer sites are now attempting to implement EHR integration. Many of the data elements captured in MOVR are not standardized fields in the health record and are found in clinical notes, which is a major barrier to successful EHR integration.

Completeness

The completeness of data in MOVR is generally very high with around 90% of eCRFs having all required fields completed. This being said, the MDA MOVR team continues to work closely with site personnel to enhance the completeness of data, including fields that are not listed as “required.” For example, the COVID-19 pandemic prevented some required functional tests such as pulmonary measurements from being performed during encounter visits, resulting in the inability to enter these data. The MDA MOVR team is also evaluating whether some data are systematically more likely to be missing due to inconsistencies in how data are reported in the EHR verses the wording of the question in the eCRFs.

Quality

Data quality is defined by the MDA MOVR team as data that is accurate and serves the purpose of advancing NMD research. Although MOVR has several processes in place to ensure that data entered into MOVR reflects the medical record, a systematic source document verification audit of MOVR Data and medical records will be completed to truly evaluate the accuracy of these data. Source document verification is planned for 2022 and a more detailed exploration of data quality will be published separately.

The MDA MOVR team also assessed how compliant MOVR is according to the recently published draft FDA guidance on assessing registries to support regulatory-decision making for drug and biological products [31]. Seven key topics were discussed in the document, including data dictionary, rules for data validations, data quality assessments and auditing, procedures for data collection, curation, management and storage, data access, data protection and security, version control, and updating eCRFs to reflect changing clinical information. MOVR meets 24 out of 31 guidelines (77%) discussed in the draft document and is currently implementing and/or working on strategies to address those guidelines that were not satisfied.

Representativeness

Patient registries often struggle achieving a representative and inclusive population, which limits the ability to accelerate research and clinical trials [32]. Datasets that do not represent a patient population as a whole are recognized as problematic in recent regulatory guidance from both the FDA and the EMA, which require that sources of bias be identified and documented if registry data are to be used as the basis of regulatory decisions [31, 33]. Our analysis of MOVR Data indicates that the MOVR participant population is not representative of the racially and ethnically diverse population of the United States, despite the indications captured by MOVR having no known ethnic biases in their incidence. Specifically, according to census data from 2021, the United States population is 59.3% White, 18.9% Hispanic, 13.6% Black and 6.1% Asian [34]. MOVR participants are 77% White, 7% Black or African American, and 2% Asian and 13% identify as Hispanic or Latino. It is not yet clear if the bias towards White, non-Hispanic participants reflects the (1) patient population at MOVR Sites, (2) the selection of patients offered participation in MOVR, and/or (3) inequalities in access to healthcare. The MDA MOVR team is developing a plan to better understand the representativeness of MOVR Data as this is a high priority for MDA and its goal of using MOVR Data to support regulatory submissions. Additionally, while data collection is currently limited to multidisciplinary care centers across the United States, expanding the MOVR Study Protocol to care centers around the world could be extremely beneficial in increasing the representativeness of the data as well as provide an opportunity to understand diagnostic journeys and disease progression at a global level. Global expansion is something that may be considered in the future after further build-out in the United States.

To add dimensionality to the data, MOVR plans to integrate patient-reported outcomes (PROs) with the existing clinic-entered dataset. PROs offer unique insights into natural history, disease progression, quality of life, and experience from the perspective of the participant [35]. When possible, PROs for individual indications will be integrated through collaborations with existing third-party registries, and where this is not possible MOVR will develop PROs de novo. MOVR is also launching a Community Advisory Committee, which will serve as a platform for MOVR participants to provide feedback on the relevance of data collected to the lived experience of NMDs, on MOVR priorities for new features and indications, and develop mechanisms that measure the success of MOVR from the participant and family perspectives. Finally, MOVR will gradually expand the number of indications to further support research in the NMD field.

Conclusion

In a fast-paced environment where the needs of drug developers and care providers are changing quickly, access to high quality clinical and patient data is essential. MOVR is a versatile and rigorous data platform designed to ensure that data from every clinic visit at participating MDA Care Centers are captured in a format that can be used for a variety of purposes. Ultimately, the existence of such a neuromuscular disease registry that is national in scope may help forestall the development of proprietary industry databases and siloing of data in the rare disease space.
