Cancer Clinical Trial

Official title: Remote Monitoring of Cancer Patients at Risk of Sepsis, a Pilot Study of Using Wearable Biosensors in Patients at High Risk of Chemotherapy Associated Neutropenic Sepsis

Status Not yet recruiting

Clinical Trial Summary

Chemotherapy is used to treat cancer in many thousands of patients per annum in the United Kingdom and millions worldwide.

Most chemotherapy suppresses bone marrow function and causes a low white cell count (neutropenia) which is a major cause of sepsis, a potentially fatal medical emergency. Best outcomes in sepsis result from early admission to hospital with the rapid start of antibiotics and supportive care. Currently, patients starting chemotherapy are told the importance of making contact with the hospital if they feel unwell or develop a high temperature. Despite this it is common for patients to delay telephoning the Cancer Centre "hot line" until after enduring many hours of symptoms and ultimately being admitted to hospital very unwell and sometimes in life threatening septic shock.

This proposal (REACT) seeks to invert the current model of care with the aim of improving patient outcomes whilst reducing costs. In this proof of concept pilot study we aim to assess the feasibility of using remote wearable biosensors to record key physiological parameters (including respiratory rate, heart rate and temperature) and transmit this data centrally to The Christie. We will also assess retrospectively whether perturbations in biosensor collected data correlate with clinical episodes of sepsis and if so develop bespoke clinical algorithms to identify patients displaying "red flags" for sepsis and guide response. Data collected by the sensors is at this stage only being reviewed retrospectively. Subsequent phases would involve recruiting larger number of patients to develop and test these algorithms with patients exhibiting 'red flags' for sepsis being contacted by the clinical team and taking appropriate action to facilitate assessment and treatment. The results of this study will determine whether working towards a randomised phase III trial comparing REACT with standard of care is an appropriate next step.

Clinical Trial Description

This is a pilot, single arm, open label feasibility study. There will be no change in patient's clinical care. Physiological data will only be analysed retrospectively.

This is a single centre trial based in a large tertiary cancer centre that treats patients across all solid tumour and haematological malignancies. Patients will be recruited from lymphoma, haematology, lung and upper gastrointestinal disease groups.

All study procedures will be performed by a researcher who is appropriately trained and who has been delegated by the PI to undertake this activity (and this is clearly documented on the delegation log). No study specific procedures will take place prior to written informed consent being provided. Study Schedule (Main Study)

The main study will consist of the following visits:

Screening Visit 1 on day one of a cycle of planned standard of care chemotherapy. This visit will include application of the wearable biosensors and training in how to use the devices including cautions and safety advice. Participants will be provided with a diary to document any issues with the device or periods where the sensors are removed. This visit will include a standard of care review by the participant's direct care team. Visit 2 on day 1 of the next cycle of chemotherapy(3 weeks after Visit 1). This visit will include a review of any device related issues by the study team and completion of the relevant event checklist (version 1.0). The study diary will be reviewed. Used sensors will be collected and replacement sensors provided. The participant will be asked to complete an interim tolerability questionnaire. This visit will include a standard of care review by the participant's direct care team. Visit 3 on day 22 of either cycle 2, 3, or 4 (3 weeks after Visit 2). This visit will include a review of any device related issues by the study team and completion of the relevant event checklist (version 1.0). The study diary will be reviewed.

Used sensors will be collected. The participant will be asked to complete an end of study tolerability questionnaire.

This visit will include a standard of care review by the participant's direct care team.

Structured interview 1-4 weeks post Visit 3 with between 10 and 20 selected participants. This visit will take place either at the Christie in a private non-clinical space or via telephone, according to the participant's preference. The IRAS Form Reference: IRAS Version 5.13 Date: 9 DRAFT interview is expected to take approximately 30 minutes. This is a semi-structured interview which will follow the interview schema (version 1.0) Sub-study: This study will consist of one visit where the participant will be shown the sensors and explained how the investigators are intending to use them. They will then be asked to complete a questionnaire about how they feel about the sensors. ;
