Workshop Outline

Introductions Overview of topic and technology Case example: Asthma study Case example: Diabetes study Potential for use in adverse event safety monitoring Checklist development: interactive process

Workshop Purpose

Clinical trial endpoints involve patient collection of physiologic and patient-reported outcome (PRO) data

Technology enables remote collection and transmission Address the opportunities and challenges of parallel

biometric-PRO data collection Empirical evidence of product value through clinical studies

conducted pre and post-launch and Ways to leverage real-time data access

Historical approach to physiologic data capture Asthma and diabetes patients monitor their conditions

regularly using peak flow meters and glucometers. Until recently, these data were collected from patients

separately from PRO data during clinical trials Increasing respondent burden Increasing risk of error associated with patients or sites

transposing and manually entering data.

Issues with manual entry of patient data Peak Flow meters:

Errors or falsification P. Verschelden et al, Eur Respir J,9,1996 A W A Kamps et al., Peak flow diaries in childhood asthma are unreliable.

Impact of electronic H. Reddel, et al., Analysis of adherence to peak flow monitoring when

recording of data is electronic. BMJ 2002;324:146-147 ( 19 January )

Manual entry problematic

Regardless of whether physiologic data are entered in paper logs or diaries or in electronic diaries prone to errors: Overreporting Underreporting Alteration of values

Unless the data are captured and transferred electronically (simultaneously), difficult to retrospectively link the data points for statistical analysis Times are off Different time settings No session to connect data

Convergence in technology

Development of biometric devices Use of electronic PRO administration (ePRO) via

PDA/handheld devices Development of integrated devices Evolution of data transmission technology Greater technologic sophistication of consumers

Result: ability to simultaneously capture and transmit physiologic and PRO parameters in clinical studies

Technology for self-management?

Wilson et al. (BMJ, 2005): “The evidence backing the use of disease-specific self-management programmes like diabetes is strong. The challenge is how to move to a programme that can support the many millions of patients who might benefit.”

Focus on mobile phone:

Equality of care – 90% of UK population owns a mobile phone

Real-time feedback, with two-way information flow

Communication with remote carer based on shared data

Economic model based on reduction in unplanned hospital admissions makes mobile phone solution a financially viable proposition

The Solution

t+ Medical Nursing Team

Prioritisation of patients• Clinical management tool• Red alert responses• Compliance monitoring• Education delivery• Medicines optimisation• Admissions avoidance programmes

Mobile health tool• Regular support from t+ telehealth nurse (based on real-time data)• Interactive to promote self management• Carer Alerts• Colour coded feedback

Healthcare practitioner

Blood Glucose Measurements

Using a glucometer to test blood sugar levels, the readings can then be downloaded wirelessly over Bluetooth to the mobile phone and submitted with the diary information to the main server.

Example patient selection

All adult or transitional (juvenile to adult services) patients with an HbA1c > 7.4%, who meet one of the following criteria:

Type 1 diabetes

Type 2 diabetes on insulin

Type 2 diabetes on oral hypoglycaemic agents, testing at least twice a week

Data Summary

Asthma Trials

Peak Flow Meter

Recording PEF ValuesCompliance with and accuracy of daily self-assessment of peak expiratory flows (PEF) in asthmatic

subjects over a three month period.

Verschelden P, Cartier A, L'Archevêque J, Trudeau C, Malo JL.Eur Respir J. 1996 May;9(5):880-5

We conclude that: 1) compliance with daily peak expiratory flow assessments is generally poor (…) and 2) a substantial percentage of values (22%) is invented.

Conclusions- Peak flow diaries kept by asthmatic children are unreliable. Electronic peak flow meters should be used if peak flow monitoring is required in children with asthma.

Peak flow diaries in childhood asthma are unreliable.Kamps AW, Roorda RJ, Brand PL.

Thorax. 2001 Mar;56(3):180-2.

eSense Case Study: Global Asthma Trial Study details

International trial with > 500 subjects in 15 countries using portable electronic PEF meter

Subjects take morning and evening PEF values using an eSense PiKo meter by Ferraris Respiratory

Data is available in real-time for review by site coordinators and sponsors

PEF Values Alerts

The following specifications should generate a patient diary alert:Peak Flow measurement less than 50% of Subject’s personal best

Explanation: The LP will update and store the Subject’s personal best Peak Flow (morning or evening) on an on-going basis, then compare every new entry to this stored value. If the new Peak Flow measurement is less than to 50% of this stored value, the LP will alert.

Alert: “You have indicated a large drop in Peak Flow. Please contact your Study Coordinator.”

Example Day 5: Subject enters 300 (LP stores personal best)Day 50: Subject enters 325 (LP updates personal best)Day 149: Subject enters 155 – LP alerts

Diary Alerts

Case Study: Disease Management

Challenge: Reduce hospitalizations and deaths due to COPD exacerbations; improve patient lung function and quality of life.

Methods: Subjects use the LogPad daily to answer questions, which are scored in real time; if the score crosses certain thresholds, patients are instructed to contact the hospital’s pulmonary call center for instruction.

Report for Patient Monitoring

Clinician Reaction

“This technology, which could easily be used with other diseases, has a truly great impact on patients’ quality of life and the disease cost and burden on society,”Dr. Wissam Chatila Temple Lung Center

Patient Reaction

"With the (LogPad) you have a daily routine, seven days a week, so you can't miss it. You can't go wrong … This here keeps me out of the hospital as much as possible. That's what I love about it."
