Next Generation Digital Natural History Study
Register HereWhat is a Natural History Study and Why Do they Matter?
Natural History Studies (NHS) are critical to the drug development process. Ciitizen has developed a new method to make this process easier. A next generation, digital NHS for CHD2-related disorders is expected to facilitate:
- Informing clinical researchers how a disease changes over time
- Enabling better endpoint selection to use in clinical trials
- Understanding the connection between mutation types and symptoms
- Reducing the time it takes to study new medicines in clinical trials
- Speeding up the time to get therapeutics to patients
- Using data as a placebo (instead of actual patients) in a clinical trial
How it Works
- Participation is completely digital - No clinic visits required
- Collects participant's medical records from the institutions visited
- Data from medical records is organized and summarized, free of charge to the participant
- Participants retain full control of their health records
- With your consent, clinicians, researchers and biopharma can access anonymized data to aid in research
- Available now in the US with plans for worldwide availability
- Registering with Ciitizen requires less than 10 minutes of your time
