Study type
Description of intervention(s) / exposure
Photobiomodulation (PBM) involves non-ionising, low power, laser light which has anti-inflammatory and regenerative effects. Laser PBM is the study intervention in this trial. Patients receive laser PBM twice per week for 6 consecutive weeks, a total of 12 sessions. During the intervention the laser is applied to the interdigital spaces of the hands and feet and the C6-T1 and L5-S1 nerve roots bilaterally.
Duration of the treatment will be approximately 30 minutes, twice a week for 6 weeks. Each point will receive a starting dose of 1 Joule for the first session, then escalated to 2 Joules per point for subsequent sessions as tolerated. The intervention will be administered by a medical professional accredited in laser safety. Each treatment, including any adverse effects, will be recorded on a case report form.
Laser treatment will be given to patients at least 3 months following completion of their systemic chemotherapy. Patients who have not completed chemotherapy are not eligible to participate.

Control group

Primary outcome [1] 322019 0
CIPN response is defined as the proportion of patients in each arm who experience either:
• resolution of symptoms from any score to zero on FACT/GOG-Ntx 13 subscale
• reduction in FACT/GOG-Ntx 13 subscale by 4 points (the minimally important difference)

Statistical methods / analysis
The total sample size will be 45 patients allowing for 10% attrition. This calculation is based on Simon's two-stage design (Simon, 1989). The null hypothesis that the true response rate is 5% will be tested against a one-sided alternative. In the first stage, 13 participants will be accrued to the intervention arm. If there are no responses in these 13 patients, the study will be stopped. Otherwise, 14 additional participants will be accrued for a total of 27 in the intervention arm. The null hypothesis will be rejected if 4 or more responses are observed in 27 patients. This design yields a type I error rate of 5% and power of 80% when the rate of response on treatment is 20%. Control participants will be recruited in a 2:1 (intervention: control) ratio until the target of 27 active participants is achieved. The estimated number of participants recruited to the control arm is 15.

Brief summary
The study aims to assess whether laser treatment (also called photobiomodulation) can help with neurotoxicity from chemotherapy. Photobiomodulation is the use of a low-power laser to improve the nerve damage.

Who is it for?
You may be eligible for this study if you are male or female, aged 18 years or older with chemotherapy-induced peripheral neuropathy symptoms. There must be at least 3 months following last exposure to neurotoxic chemotherapy, including taxane and platinum classes.

Study details
All participants in the study will be randomly allocated (50/50) chance to one of the following treatments:
1. Laser treatment to the hands, feet and back for 6 weeks.
2. The control treatment, which is the same (including laser treatment), however the laser source is covered up. This means people in the control group do not know which treatment they are getting. During the study, the participants wear black goggles to prevent them from identifying their treatment. While on the study, participants will be asked about their symptoms, their day-to-day function and have a physical exam focused on nerves.

It is hoped this laser treatment will improve nerve symptoms in the patient population and help inform a larger study with more patients.
