VitalTraq for the Detection of CRS

Digital Multi-Vital Sign Monitoring for Early Detection of Cytokine Release Syndrome From Bispecific T-Cell Engagers and Chimeric Antigen Receptor Therapy

The purpose of this study is to evaluate two vital sign monitoring devices, TempTraq and VitalTraq, in patients with hematologic malignancies undergoing therapy with Chimeric antigen receptor T-cell therapy (CAR-T) or Bispecific T-cell engagers (BiTE) products. TempTraq is an axillary patch that is worn on the skin and continuously monitors a patient's body temperature. VitalTraq is a smartphone application that utilizes remote photoplethysmography technology via a 30-second facial scan to estimate the patient's blood pressure (BP), heart rate (HR), heart rate variability (HRV), and respiratory rate. These remote vital sign monitoring devices have the potential to promote earlier detection and intervention of treatment-related toxicities, including cytokine release syndrome (CRS) and febrile neutropenia.

Intervention / Treatment

Experimental: Patients with hematologic malignancies; Patients who are scheduled to receive CAR-T or BiTE through the Duke Adult Blood and Bone Marrow Transplant (ABMT) and Hematologic Malignancies Program.

Device: TempTraq; TempTraq (Blue Spark Technologies, Westlake, OH) is an FDA 510K cleared wearable, wireless temperature monitoring patch designed to continuously monitor and track body temperature.; Device: VitalTraq; VitalTraq (Blue Spark Technologies, Westlake, OH) is an experimental and novel multi-vital sign monitoring platform that allows for interval measurements of heart rate, heart rate variability, and blood pressure.

What is the study measuring?

Primary Outcome Measures

Outcome Measure	Measure Description	Time Frame
TempTraq's Ability to Measure Axillary Temperature in the Intended Use Population	Body temperature (degrees Celsius) data will be measured as a continuous variable via the TempTraq device and via standard-of-care oral thermometers. Reported as the difference between the two measurements (TempTraq - SOC thermometers).	Day 14

Secondary Outcome Measures

Outcome Measure	Measure Description	Time Frame
Lead Time by Which Fevers Can be Detected Using TempTraq Compared to SOC Interval Oral Thermometer Measurements	The times to first detection of fever, if applicable, will be measured for each patient using temperature data derived from the TempTraq device and standard-of-care oral thermometers. The mean time to first fever (i.e., temperature > 38 degrees Celsius), will be calculated and described for both the TempTraq device and standard-of-care oral thermometers. Reported as the difference between the two measurements (TempTraq - SOC thermometers).	Day 14
VitalTraq's Ability to Measure Blood Pressure in the Intended Use Population.	Determined by use of an equivalence test to test the hypothesis that there is no difference in the systolic and diastolic measurements using VitalTraq compared to SOC interval vitals measurements. The smallest tolerable differences in systolic and diastolic blood pressure are set to be 20 mmHg and 10 mmHg, respectively. Reported as the difference between the two measurements (TempTraq - SOC).	Day 14
VitalTraq's Ability to Measure Heart Rate in the Intended Use Population.	Determined by use of an equivalence test to test the hypothesis that there is no difference in the heart rate measurements using VitalTraq compared to SOC interval oral thermometer measurements. The smallest tolerable difference is set to be 10 beats per minute. Reported as the difference between the two measurements (TempTraq - SOC).	Day 14
Patient's Perspective on the Burden of Using TempTraq and VitalTraq	Individual questions in a post-intervention survey feature 7-point Likert scale responses, where 1=strongly agree and 7=strongly disagree. The mean score is reported, giving a score range of 1 to 7, where a lower score indicates lower burden.	Day 28
Lead Time by Which TempTraq and VitalTraq Can Detect Grade 2 or Higher Cytokine Release Syndrome (CRS) as Compared to the Standard of Care.	The times to first detection of grade 2 or higher CRS, if applicable, will be measured for each patient using vitals data derived from the TempTraq and VitalTraq devices, as well as via standard-of-care vitals measurements. The mean time to first detection of grade 2 or higher CRS will be calculated and described for both the investigational devices and standard-of-care monitoring. Reported as the difference between the two measurements (TempTraq - SOC).	Day 14
