- Brief Summary
The goal of this prospective, interventional, single-center study is to assess whether the early detection of Influenza with smart wearable device algorithms and alerting, rapid testing, and subsequent Baloxavir treatment demonstrate better post-infection outcomes versus publicly available- and Centers for Disease Control (CDC)-derived national statistics for equivalent household populations as well as pediatric kidney, heart, liver, lung transplant recipients and waitlisted patients.
- Detailed Description
Influenza infections are a significant concern for the clinical management of transplant recipients, a highly vulnerable immunocompromised patient group. Early Influenza detection has major benefits for the successful treatment in that crucial early infection time window and allows for more timely mitigation measures to be employed. Xofluza® (Baloxavir Marboxil), FDA approved in 2018 for the treatment of acute Influenza, has been shown to have improved outcome characteristics versus Tamiflu® (Oseltamivir), as well as compliance (a single pill given once, versus 10 pills taken over 5 days for Oseltamivir). The timing of the influenza diagnoses and intervention greatly impacts the outcomes in both antiviral medications though. Smart wearable devices have demonstrated clear utility to detect early infection using physiological signatures such as sub-symptomatic increases in heart rate (HR) and body temperature. Detection of Influenza and severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) have been shown to be robustly detectable several days prior to clinical symptoms onset in large well-powered smartwatch studies.
This is a sub-study of the existing Institutional Review Board (IRB) # 20-017872 protocol: "Early Detection of SARS-CoV-2 \& other Infections using Wearable Devices in Pediatric Transplant Patients and Household Members". This is a prospective, interventional, single-center study at The Children's Hospital of Philadelphia comprising kidney, heart, liver and lung transplant recipients, waitlisted patients, and their household members. Subjects will wear smart wearable devices to monitor biometrics including HR, HR variation (HRV) and proxies of body temperature. A smart wearable device alert generated from a validated early infection detection algorithm and alerting platform, precipitates subjects to use an at-home collection kit for SARS-CoV-2, Influenza A/B and respiratory syncytial virus (RSV) A/B which is then sent to a central clinical lab for polymerase chain reaction (PCR)-based diagnoses. If the transplant recipient is positive for Influenza A/B the local clinical care team will be informed to determine if Baloxavir and/or any other medication is warranted. Genentech will make the Baloxavir medication available via the CHOP transplant pharmacist through the recipients' regular pharmacy. If the non-transplanted household members are positive for Influenza or exposed to Influenza positive infected subject(s) their treatment will be determined by their own primary-care. All CHOP transplant recipients will have their medical records reviewed for relevant covariates and confounders after Baloxavir treatment. Study subjects will complete short daily REDCap symptom forms for the pre-, peri- and post-infection periods.

Group Intervention Description Population 1: Transplant Recipients Baloxavir Marboxil Participants who are a CHOP kidney, heart, liver or lung single or multiple transplant recipients aged 5 years or older will receive a single dose of Baloxavir. Population 2: Waitlisted Patients for Transplant Baloxavir Marboxil Participants who are waitlisted CHOP kidney, heart, liver or lung single or multiple transplant recipients aged 5 years or older will receive a single dose of Baloxavir marboxil. Population 3: Household Members (Non-Transplant) Baloxavir Marboxil Non-Transplanted Household Members aged 5 years or older will receive a single dose of Baloxavir marboxil.
- Primary Outcome Measures
Name Time Method Time-to-Clinical-Response 30 days post-Baloxavir treatment For subjects infected with Influenza investigators will assess Time-to-Clinical-Response in a time frame up to 30 days post Baloxavir treatment in this study vs comparable data available from national control groups. Time to Clinical Response is based on: (a) temperature ranges as measured by (standard of care and/or smartwatch biometric data), oxygen saturation, respiratory status, HR, and hospitalization status; (b) return to healthy baseline data including from biometric data derived from the subjects' smartwatch; (c) time to symptom resolution in a time frame up to 30 days post Baloxavir treatment as assessed from a return to healthy baseline on the daily questionnaires).
Incidence of complicated hospital stay(s) 30 days post-Baloxavir treatment Incidence of complicated hospital stay(s) for a time frame up to 30 days post Baloxavir treatment in this study versus comparable data available from the previously described national control groups. A complicated hospital stay is defined as a hospital admission that was either prolonged (greater than 7 days), requiring ICU level of care or death at day 30 as a result of influenza infection.
- Secondary Outcome Measures
Name Time Method Incidence of Respiratory Tract Infection Progression Following Treatment 30 days post-Baloxavir treatment Progression to lower respiratory tract infections in a time frame up to 30 days post Baloxavir treatment in this study versus comparable data available from national control groups.
Oxygen requirement Following Treatment 30 days post-Baloxavir treatment Oxygen requirement in a time frame up to 30 days post Baloxavir treatment in this study versus comparable data available from national control groups.
Rate of Respiratory Failure Following Treatment 30 days post-Baloxavir treatment Rate of respiratory failure in a time frame up to 30 days post Baloxavir treatment in this study versus comparable data available from national control groups.
Length of hospital Stay Following Treatment 30 days post-Baloxavir treatment Length of hospital stay in a time frame up to 30 days post Baloxavir treatment in our study versus comparable data available from national control groups.
30-day Mortality Rate Following Treatment 30 days post-Baloxavir treatment 30-day mortality for post Baloxavir treatment in this study versus comparable data available from national control groups.
