Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment Group A - Heat Treatment - usual treatment to manage symptoms and heat treatment. The participant will continue to have the same treatment they would have had if they were not in the trial and will be asked to put their hands and or feet on a heat pad for 20 minutes a day (tailored according to patient tolerance to a minimum duration of 10 minutes), 4 times a week, for 4 weeks. A heat pad will be provided to the participant. A study nurse will provide education regarding heat pad use to the participant via phone or web based teleconferencing.
Treatment Group B - Massage Treatment - usual treatment to manage symptoms and massage treatment. The participant will continue to have the same treatment they would have had if they were not in the trial and will be asked to massage their hands and or feet using a massage ball for 5 minutes a day, 4 times a week, for 4 weeks. The participant will be provided with a small massage ball (approximately 10cm diameter) with raised finger-like protrusions to aid the massage. A study nurse will provide education regarding massage ball use to the participant via phone or web based teleconferencing.
Treatment Group C - Heat and Massage Treatment - usual treatment to manage symptoms, heat and massage treatment. This treatment is for 4 weeks and includes usual treatment plus both heat and massage treatment. A study nurse will provide education regarding heat pad and massage ball use to the participant via phone or web based teleconferencing.

Participants will be allocated to usual care or Treatment A for the first 4 weeks of the study.
At the end of week 4, participants will be asked to complete surveys and the response to treatment will be calculated. If the participant in the usual treatment group has not had a response to usual treatment at the end of 4 weeks, they will be re-allocated to either Treatment A or B for weeks 5 to 8. If the participant in the Treatment A group has not had a response to treatment at the end of 4 weeks, they will be re-allocated to Treatment B or C for weeks 5 to 8. If the participant has had a response to usual treatment or Treatment A in the first 4 weeks they will remain on the same treatment for weeks 5 to 8.

Fidelity of the intervention will be assessed using the framework for behavioural interventions recommended by National Institutes of Health (NIH, US).

Intervention Fidelity Strategies
Study Design procedures have been designed to ensure that the study can adequately test its hypotheses in relation to the underlying theory and clinical practices.
Training Providers: standardized provider training includes procedures to ensure that interventionists have been satisfactorily trained to deliver the intervention to study participants. This will involve:
o Provision of a study manual to all staff which includes:
o Generic study related information: standard operating procedures, study overview, reporting/documentation guidelines, communication flowchart, rationale for the study treatment, treatment side effects
o Intervener specific information: Job description, intervention protocol, related literature, quality assurance and monitoring
o Training program including didactic presentations, performance assessment and role play
o Manualised intervention protocol
Delivery of Treatment: Treatment procedures will be monitored to improve delivery of intervention and comparison of conditions, and ensure that treatment is delivered as intended, through:
o Bi monthly teleconferences
o Quality assurance monitoring – first five sessions observed by trial manager (trainer), and self and trainer assessment completed using a checklist; if performance is satisfactory at this point one session per month will be recorded and self and trainer assessment completed with feedback provided on performance.
o Omissions and/or protocol deviations with interveners reviewed on an individual basis.
o Intervention checklist completed at the end of each intervention to allow protocol deviation tracking across interveners and conditions.
o Minimising contamination between conditions by training interveners to address participant questions about randomisation and their assigned condition using non-biased explanations
Receipt of Treatment: Treatment receipt focuses on the participant and includes procedures to assure that the treatment was both received and understood. This will be achieved by:
o Ensuring participants understand the information provided in intervention, by checking through use of active questions and behavioural observations
Enactment of Treatment Skills: Enactment of treatment skills includes processes to monitor and improve participant ability to perform treatment-related behavioural skills and cognitive strategies in relevant real-life settings as intended. This will be achieved by:
o ensuring participants are able to demonstrate use of treatments through observing at least one practice session and recording observations in Intervention checklist at the end of each session
o checking in with participants a minimum of once, up to 3 times in the first week of commencing the first intervention, then weekly until the end of the trial period

Intervention Adherence - participants will be asked to complete diaries to record intervention sessions and standard care treatments.

Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation is concealed using a central randomization system accessed via computer
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Randomisation will be determined using a computer-generated sequence of numbers for each site to randomly allocate patients to a specific treatment. Randomisation schedules will be developed for each site using random number tables, generated at a central registry. Treatment for each patient will be allocated according to a block randomisation schedule held by the central registry. Block randomisation within the centre will ensure even allocation to each code in each site, and sites will not be informed of the block size due to the lack of blinding.

Efficacy
Statistical methods / analysis
Assuming the required minimum difference in proportions between the two groups is 20%, to achieve 80% power for a one-sided test and 95% level of confidence, the required minimum sample size at Stage 2 is 55 per non-responder group. As the intervention is undertaken by individuals at home, and study outcomes relate to each individual’s health behaviours, we have estimated a minimal intra-cluster correlation (ICC) of 0.01. The proportion of non-responders to the initial interventions is not known, so we estimate 70% non-response to heat therapy. Allowing 30% for attrition at 6 months, 10% for confounders, and an effect size of 1.2, working backwards from the required sample size of 55 per non-responder group at Stage 2, the estimated minimum total sample size for randomisation is 640 (320 per group).
Outcomes will be assessed on a priori hypotheses, with each endpoint being considered separately in the analysis.
Objective 1. The primary outcome variable Y is ‘response to treatment’ (yes/no) at 4 weeks. Response is defined as greater than or equal to 20% reduction from baseline as assessed by the EORTC CIPN20 sensory scale. Response indicates improvement in each variable being assessed (e.g., sensory symptoms).
Primary hypothesis, H1: The impact of the initial intervention in Stage 1 will be assessed in both an unadjusted and adjusted logistic regression analysis of the response to treatment at 4 weeks (Y), comparing Intervention A (heat therapy) and standard treatment groups, and adjusting for covariates such as adherence, time since treatment, site, and baseline variables correlated with Y. Odds ratios and 95% confidence intervals will be reported.

Secondary hypotheses, H2 and H3: Similarly, unadjusted and adjusted logistic regression analyses, adjusting for covariates will be conducted to assess the impact of the adaptive interventions at Stage 2, to determine: (1) for non-responders to initial Standard Care, the impact of the alternative interventions (A and B); and (2) for non-responders to initial Intervention A, the impact of the alternative interventions (B and C).

Additional secondary hypotheses, H4 and H5: Similar to the above analyses at Stage 1 and Stage 2, logistic regression analyses will be conducted, but the outcome variables in each analysis will be the proportion of responders with: (1) CIPN motor symptoms; and (2) autonomic symptoms; (3) high levels of depression; (4) high levels of anxiety; and (5) low quality of life.

For outcome variables other than Anxiety and Depression measures (STAI and CES-D), the overall change over time (0, 4 and 8 weeks, 3 and 6 months) between intervention groups and (time*group) interaction effects will be examined, with adjustment for covariates using GLMMs. For the outcome variables measuring Anxiety and Depression, the overall change over time (0, 4 and 8 weeks) between intervention groups and (time*group) interaction effects will be examined, with adjustment for covariates using GLMMs. If there are missing data, analyses are based on the assumption that data are missing at random. GLMMs will allow the inclusion of all available data, including those participants who do not complete all assessments.
Evaluation of the first-stage interventions requires pooling Y from the adaptive subgroups 1 to 3 and comparing the resulting average to the pooled Y from subgroups 4 to 6, This analysis over 8 weeks assesses the difference between the Stage 1 interventions (Standard care vs heat therapy), averaging over the Stage 2 intervention options. There will be no imputation for missing data.
Objective 2. To identify the best performing adaptive intervention embedded within the SMART design, we will order the embedded interventions in terms of the largest average reduction in CIPN to the smallest reduction.
Objective 3. Determinants of CIPN will be assessed using GLMMs for separate analyses of each of the subscales and the total CIPN scale and potential predictors such as time since treatment and demographic variables.
Objective 4. Economic evaluation: The primary measure for the economic evaluation for each trial arm will be the cost (healthcare provider perspective) per Quality Adjusted Life Year (QALY), derived from participants’ EQ-5D-5L assessments and estimated using an area under the curve approach. Incremental cost-effectiveness ratios (ICERs) will be used to estimate the comparative cost-effectiveness of the respective intervention approaches consistent with the trial arm comparisons outlined above. Healthcare resource utilisation will be collected for the duration of the trial using the health resource questionnaire and directly from the Australian Department of Human Services (Medicare and Pharmaceutical Benefits Schemes databases). This evaluation will include both labour and non-labour resource utilisation from each trial arm, which may include usual care, hospitalisations, community-based health services, and other healthcare-associated resource use (e.g. G.P. visits, medicines captured through MBS and PBS). Resource utilisation will be costed at market rates. Detailed pathway analysis will specify all resource consuming intervention and usual care healthcare activities for each trial arm path. The primary trial-based time-horizon for the economic evaluation will correspond with the final re-assessment. Due to the potential for uncertainty and non-normal distribution for the primary-trial based analysis, 95% confidence intervals (for costs and QALY estimates) and a 95% confidence ellipse (for incremental cost effectiveness ratio estimate) will be derived from bootstrap resampling (2000 replications of original sample size). However, if between group differences in health-related QoL remain at 6 months, QALYs will be probabilistically modelled (using discrete event simulations) under an assumption that between group differences in health-related QoL will diminish over time until a complete convergence is observed (probabilities and distributions for QALY modelling will be based on best evidence from the trial and prior longitudinal investigations of survivorship, cancer recurrence and QoL among comparable cancer populations). Cost effectiveness acceptability curves for varying threshold values of cost effectiveness will be prepared. An assessment of the sensitivity of the results obtained to variation in measured resource use, effectiveness, time-horizon, discounting, and unit costs will be undertaken where indicated using appropriate sensitivity analyses. This trial based economic evaluation with additional (and cost-efficient) modelling of QALYs will provide health service decision makers with clear probabilistic cost-effectiveness data necessary for informed resource allocation decision making. The economic evaluation will be conducted and reported according to the Consolidated Health Economic Evaluation Reporting Standards statement and supervised by CIF McPhail.
Objective 5. Genetic analyses: For each polymorphism, four genetic models (i.e., multiplicative, additive, dominant, recessive) will be tested, adjusting for differences in ethnicity, population stratification, and data-driven covariates (e.g., age). Null SNPs will be employed to assess and adjust for population stratification using principal components analysis. Logistic regression will be employed to test for differences in genotype frequency between patients with and without poorer CIPN outcomes, while adjusting for other covariates (e.g., age, diagnosis).

Summary
Brief summary
The purpose of the proposed study is to evaluate effectiveness and cost effectiveness of heat therapy and/or massage in addition to standard care in people with chemotherapy induced peripheral neuropathy.

Who is it for?
You may be eligible to join this study if you aged 18 years or over and meet study definition of chemotherapy induced peripheral neuropathy.

Study details
Patients will be assigned on a 'chance' basis, (like flipping a coin) to receive standard care or an intervention of standard care and heat therapy treatment for four weeks. If after four weeks the intervention decreases CIN nervous system symptoms then the intervention will continue for another 4 weeks. If symptoms do not improve, then the patient will be assigned on a chance basis to receive an alternative intervention of standard care and heat therapy, standard care and massage or standard care, heat therapy and massage. The second intervention will then be received for four weeks.
Chemotherapy induced peripheral neuropathy has become a significant health issue which can cause treatment delays and affect functional abilities and quality of life. There are currently no pharmacological interventions that effectively prevent or manage CIN.
