Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients due to receive chemotherapies carrying a high risk of febrile neutropenia will be screened and will give informed consent before febrile neutropenia onset. Patients who consent to the study will be randomised on a 1:1 ratio to receive oral paracetamol (1g six hourly) or matching placebo during the first 42 hours of febrile neutropenia. Upon the development of febrile neutropenia patients will commence their allocated treatment after starting antibiotic therapy.

Whilst in hospital with febrile neutropenia, study participants will have daily blood tests over and above those taken for standard of care. Tests will look at markers of inflammation and the level of bacteria in participants’ blood.

Participants will also be asked to fill in a short quality of life questionnaire each day. On the third day, two more detailed quality of life questionnaires and a questionnaire about their experience of the study will need to be completed.

All participants will be inpatients in Wellington hospital. Adherence to study treatment will be monitored by reviewing the participants' medication chart, as the study treatment/placebo will be prescribed on this and individual doses will be signed for by the administering nurse or doctor. If a participant is discharged home prior to completing the course of study treatment, that participant will come off study.

Outcomes
Primary outcome [1] 289676 0
This is a feasibility study with the aim of proceeding to a multicentre study should the result of this study be positive. The study will collect information on the primary and secondary endpoints proposed for the full study. However, this feasibility study is not statistically powered to detect differences between the study groups in these endpoints.
Primary endpoint: The proportion of patients who are successfully treated by 72 hours from the time of initiation of study therapy. ‘Successful treatment’ will be defined as survival with no documented fever of greater than 38 degrees centigrade in the preceding 12 hours, with no change of initial antimicrobial therapy, with no serious medical event (defined as hypotension with systolic BP <90mmHg for >1 hour, respiratory failure requiring invasive or non-invasive ventilation, or intensive care transfer) in the preceding 72 hours, and no recurrence of fever seven days after cessation of first-line antibiotics.
Timepoint [1] 289676 0
Successful treatment will be determined by assessment at 72 hours and by review of medical notes and by follow-up telephone call 30 days after febrile neutropenia onset.
Secondary outcome [1] 302986 0
Quality of life
Timepoint [1] 302986 0
The EQ-5D-5L quality of life questionnaire will be assessed daily during the first 72 hours of febrile neutropenia. At 60 – 92 hours, quality of life will be assessed using the FACT-N questionnaire.
Secondary outcome [2] 302987 0
Bacterial load
Timepoint [2] 302987 0
Peripheral blood taken at 0, 24 and 72 hours of febrile neutropenia will be used to assess bacterial load by quantitative PCR for the conserved bacterial gene for 16S ribosomal RNA.
Secondary outcome [3] 302988 0
Duration of hospital stay
Timepoint [3] 302988 0
This will be determined by review of medical records on day 30 after febrile neutropenia onset
Secondary outcome [4] 302989 0
Overall survival
Timepoint [4] 302989 0
This will be determined by medical notes review and telephone call on day 30 after febrile neutropenia onset

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Placebo- and paracetamol-containing study packs will be prepared by Optimus Healthcare (4 Walls Road, Penrose, Auckland, PO Box 99-467, Newmarket, Auckland), and will be serially numbered according to a randomisation sequence generated by the study statistician. The packs will be produced in duplicate, and will be distinctly labelled, to allow distribution of one pack to the study participant, and a back-up pack to be held securely on the haemato-oncology ward in case the study participant presents with febrile neutropenia but without bringing their study pack. A 1:1 ratio of paracetamol to placebo will be used. There will be no stratification for this feasibility study.
Potential participants will be identified before the onset of febrile neutropenia, and offered study participation. Participants who agree to take part and sign consent will be screened to ensure they meet criteria for study entry. Participants who meet inclusion criteria and are not excluded will be given the next sealed study pack in numerical order. Staff and patients will be blinded to the treatment allocation.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A computer-generated blocked randomisation sequence using randomly-selected block sizes will be produced by the study statistician. No stratification will be used.

Statistical methods / analysis
This is a feasibility study designed to assess critical questions for the design of a subsequent phase III trial. It is not statistically powered to answer the primary or secondary endpoints of the main trial, although these endpoints will be assessed to evaluate the case report forms and study design.

This feasibility study will address four feasibility issues as follows:
1. Temperature separation: Temperature separation will be assessed by comparison of mean peak daily temperatures and mean average temperatures between the two randomised groups.
2. Acceptability of treatment: Acceptability of allocated treatment will be by measurement of the proportion of randomised participants in each group who were withdrawn from the study or received other methods of temperature control. A discontinuation form will assess reasons for exit from the study protocol to identify ways of mitigating withdrawal in a modified protocol.
3. Bacterial load: The utility of serial qPCR measurements of the gene encoding bacterial 16S rRNA will be assessed by receiver operating characteristic curves for the presence or absence of a good outcome. If the area under the curve for this outcome is greater than 0.75 then we plan to use this as a secondary outcome variable in the main study.
4. Recruitment rates: In order to complete recruitment in less than two years we need no less than 75% of the recruited participants to fully adhere to the treatment protocol based on a recruitment rate into the study of 75% so that the effective recruitment rate is greater than 56%. We anticipate that there will be 90% full adherence to the treatment protocol. The lower 95% CI for a proportion for 25/28 is 77.8%, so that if the achieved adherence rate is 90% in conjunction with a recruitment rate of 75% we are confident that the main study can complete recruitment in under two years. If adherence to our draft protocol is lower than anticipated we will need to change the protocol to improve adherence or recruit additional centres for any subsequent multicentre trial.

Summary
Brief summary
The aim of the study is to discover the impact of using paracetamol during febrile neutropenia, a common type of infection after chemotherapy.
At present, about half of patients receive paracetamol to lower their temperature during febrile neutropenia in our hospital department. Whether or not someone receives paracetamol is at the discretion of the patient’s doctor or nurse. We do not know whether paracetamol is beneficial or not. On the one hand, paracetamol can lower fevers and can make people feel more comfortable. On the other hand, fevers are part of the body’s natural response to an infection and lowering a fever with paracetamol might delay recovery from an infection.

We propose a large study to answer the question of whether paracetamol should be used in febrile neutropenia or not. However, before we can do the large study necessary to answer this question, we need to do a smaller study (this study) to ensure that the large study can be achieved. Specifically, we need to check that people receiving paracetamol have a lower temperature than those receiving placebo, that the study treatment is acceptable, that we can detect bacteria in the blood at low levels, and that we can recruit enough patients for the large study.
