WornWell Bio
Biostatistics for wearable motion & heart-rate data in clinical trials.
We help you turn wearable motion and heart-rate data into clinical-grade endpoints that hold up under review, from data cleaning and compliance through analysis and reporting.
What we do
From messy, high-volume sensor data to endpoints that hold up
Most teams now have the wearable data. Fewer have the capacity to clean it, understand compliance, and make it count. We close that gap directly, or build it into your team.
- Statistical Analysis Plans for wearable and digital endpoints
- Data cleaning, QC, and validation programming
- Wear-time compliance and data-yield reporting
- Statistical modeling and analysis
- Clinical anchoring to scales and patient-reported outcomes
- Reporting, manuscripts, and clinical interpretation
- Training and enablement for in-house teams
Who we work with
Built for clinical and research teams
Pharma & biotech
Wearable and digital endpoints, from endpoint definition and SAP through primary analysis and submission support.
CROs
Specialist capacity for wearable endpoints without adding headcount. Hand us the sensor-data work, or bring us in to build the capability in-house.
Academic medical centers
Rigorous, reproducible analysis and publication support for investigator-initiated and grant-funded research.
Hands-on experience with APDM Opal, Garmin, Fitrockr, and research actigraphy, and ready to adapt to whatever device your trial runs on. Explore platforms →
About
Built on nearly a decade of wearable trials and biostatistics
WornWell Bio is led by founding biostatistician Daniel Muzyka, M.Sc. Daniel currently serves as lead statistician for the wearable sub-study of a large, multi-site cardiovascular clinical trial, directing Garmin-based digital biomarker analysis and the sponsor's broader wearables research agenda. Before that he spent several years on the statistical analysis of APDM Opal precision motion data across CNS diseases, in collaboration with the balance and gait group led by Dr. Fay Horak at OHSU.
Daniel leads and reviews every engagement personally, drawing on vetted specialist subcontractors when scope requires, all under the same SOPs, NDAs, and QC standards. We work in SAS and R and align deliverables with FDA digital health technology guidance and ICH E9(R1) estimands.
