Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The study intervention consists of electroacupuncture (EA) administered once a week over ten weeks, with a total of 10 treatments for each participant. The participants will receive EA at the following locations: upper limb - LI4, TE6, Baxie (M-UE-22) and lower limb - ST36, LR3, bafeng (M-LE-8). The needles in the webs of the toes and fingers will be inserted to the depth of between 5 to 10mm at (Baxie and Bafeng acupoints) and 10 – 13mm at the remaining acupoints. Single-use disposable stainless steel Dongbang needles (0.20 x 15mm) will be used. Leads from the EA machine (ITO Co Ltd, 143609 Acuneeds Australia Pty LtD – stimulator, electrical, acupuncture) will be placed on the points Baxie and Bafeng. The electrostimulation will be delivered at a low frequency (2 Hz), on a disperse continuous setting, with moderate intensity. Duration of each treatment will be 45 minutes where the intervention will be administered by a registered acupuncturist with oncology experience. The timing of intervention administration will be timed +/- 2 days pre-infusion (weekly), this will usually be the same day as routine blood test prior to infusion. Adherence to the intervention will be monitored with a session attendance checklist, which will also be checked weekly.
Intervention code [1] 322496 0
Treatment: Devices
Comparator / control treatment
The frequency and duration of the intervention will be the same as the active EA group. The participants will receive sham-EA at the same acupoints as the active group. The sham-acupuncture will be a non-penetrative method where a specialised device called a ‘Streitberger needle’ will be used to elicit a similar sensation only on the surface of the skin. Leads from the EA device will be attached to the sham device at prescribed acupoints with no electrostimulation administered. To allow the treatment to appear realistic the machine will be turned on, the machine will sound a beeping noise while switched on, however the leads will be connected to a terminal without stimulation. The sham-EA will be applied over true acupoints without manual or electrical stimulation.

Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation sequence and participant assignment to the intervention will be completed by the biostatistician. Allocation concealment will be achieved via opaque sealed envelopes.

Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Eligible participants will be assigned to either EA or sham-EA group with a 1:1 allocation rate as per computer-generated randomisation scheduled using random permuted block sizes. The study participants will be blinded to group allocation until the end of the study after the final assessments.

Sample size estimation:
As this is a phase II pilot study, the sample size calculation was based on the detection of an effect size of 0.8 (“large effect size”) in any of the continuous measures. The results obtained from this study will inform targeted sample size calculations in a future prospective trial. Using a two-sample t-test and assuming equal numbers in EA and sham-EA groups, and equal variances in the groups, a total of 40 participants (20 per treatment arm) will provide 80% power at a two-sided significance level of 5%, allowing 20% drop-out rate, to detect a “large” change in a continuous outcome measure.

Statistical analysis plan:
• The statistical analysis will be performed by a qualified biostatistician who will be blinded to the group allocation. Subjects will be analysed according to the intention to treat principle.
• Demographic characteristics and baseline scores summarised as mean (SD) for continuous variables or medians (quartiles) if the distribution is skewed. Counts with percentages will be presented for categorical variables.
• The primary endpoints will be summarised as counts (percentages) (i.e., recruitment rate, adherence rate, successful blinding of participants, compliance with follow up) or means (standard deviations) (i.e., patient overall satisfaction of intervention and practitioner overall satisfaction), by treatment group.
• Secondary outcomes will be summarised as mean (SD) by treatment group at each time point of interest. Generalised estimating equations (GEE) will be used to assess the effect of treatment over time.
• The main CIPN assessment will be the change in EORTC QLQ-CIPN20 score from baseline to end of treatment (t10). The mean change in each treatment group will be summarised as mean (SD) and compared using a nonparametric test (Mann-Whitney). Covariables of interest will include age, gender and BMI. Results will be presented with 95% confidence intervals and p-value. No interim analysis will be carried out for this study.
• The primary analysis will be on a complete case basis. If there are missing data values, multiple imputation will be used to provide a sensitivity analysis.
