What Vitalograph Offer

A cough study’s success depends on swift, accurate, high-quality data. The VitaloJAK® Cough Monitor provides the only fully validated system for objective measurement of cough with median sensitivity >99% and excellent integrity.

Our compact, mobile monitoring system allows home-based ambulatory recording over 24 hours, allowing subjects to continue their normal daily activity while participating in your trial. Cough recordings undergo centralised, semi-automated analysis to provide quantified data. The VitaloJAK algorithm removes non-cough data from cough recordings, reducing the file size to allow efficient analysis by trained cough analysts.

VitaloJAK is a validated, 510k cleared and CE marked medical device system.

Our experienced teams include cough, project and data management experts. They coordinate and manage all the project essentials for the Vitalograph aspect of the study including project planning, risk assessment, budget control, tracking information, creating customisable reports, reviewing data, status updates and change control. Their aim is to ensure that your trial runs smoothly, on time, to scope and on budget.

Our Experience

Highly experienced cough experts, innovative devices, our unrivalled experience is at your disposal.

The VitaloJAK® Cough Monitor has proven suitable for quantifying 24 hour cough sessions in large Phase 2 and 3 studies where other methods of cough data collection and analysis are too costly, time consuming or inconsistent. 

The system has been used for research since 2005 and in phase 2 and 3 studies globally since 2014. It has been fully validated by the specialist cough research unit at the Manchester University NHS Foundation Trust UK, through multiple phase 1 and academic research studies.

Measurement Objectives & Endpoints

The objective frequency of cough is the preferred assessment of cough in clinical trials.

We offer a robust, customisable system for the measurement and analysis of cough study data in Phase I – IV trials. The study reports can be tailored to your needs so that the primary, secondary and/or exploratory endpoints can be reviewed on a regular basis, giving you live overview of your study.

CriteriaExample Endpoints
Cough counts
  • Cough count over the 24-hour recording
  • Cough count per hourly segments
  • Including screening, baseline and treatment counts.
  • Change from baseline in awake cough frequency
  • Sleep / wake events
  • Quality events
