• Registration Number: NCT06769061
• Lead Sponsor: Karen Kar Loen CHAN

Brief Summary

Objectives:

To explore the feasibility and effectiveness of acupuncture on reducing Chemotherapy Induced Peripheral Neuropathy (CIPN) in gynaecological cancer patients who have received carboplatin and paclitaxel chemotherapy combination. Results of this pilot trial will provide preliminary information for a potential a larger scale multicentre study.

Hypothesis:

Acupuncture can significantly reduce CIPN in gynaecological cancer patients treated with chemotherapy

Design and subjects:

This is a pilot, prospective randomised controlled trial. This is an exploratory trial to evaluate the feasibility and effectiveness of acupuncture in reducing CIPN in gynaecological cancer patients. Eligible patients will be 1:1:1 randomised to three groups: electroacupuncture group, sham acupuncture group and waiting-list (usual care) control group. For electroacupuncture and sham acupuncture groups, the assessors and the patients will be blinded to the treatment given.

1. Electroacupuncture group - patients will receive 6 weeks of electroacupuncture, 2 sessions per week, by a qualified Traditional Chinese Medicine practitioner from the School of Chinese Medicine.

2. Sham acupuncture group - patients will receive 6 weeks of sham acupuncture similar to the above.

3. Waiting-list (usual care) control group - patients will not receive any treatment.

Main outcomes:

Acupuncture effects will be assessed at baseline and 3, 6,12 weeks post intervention by:

1. Patient reported outcome measures: FACT/GOG-Ntx questionnaire for assessing CIPN symptoms and EORTC-QLQ-C30 and CIPN20 questionnaires for assessing quality of life symptom

2. Clinician reported outcome measures: NCI-CTCAE grading for CIPN by clinicians and Semmes-Weinstein monofilament test as an objective measurement of CIPN.

Data analysis:

Intention to treat analysis will be carried out. Baseline demographics will be compared between the 3 groups. Change from baseline total score will be calculated and analysed using 2-sample t-test. 95% CI will be reported for treatment differences. Score for different subcategories will be analysed in a similar manner. Data collected at week 6 will be used for outcome analysis. P\<0.05 will be considered as statistically significant. Acupuncture efficacy, effectiveness and placebo effect will be indicated by comparison of acupuncture vs. sham acupuncture, acupuncture vs. waiting-list, and sham acupuncture vs. waiting-list, respectively.

Expected results: Patients in the acupuncture arm will have reduced numbness and peripheral neuropathy and improved quality of life without any adverse event.

Detailed Description

Subjects will be recruited by research assistant at the gynaecological oncology clinics at Queen Mary Hospital. All potential subjects will be required to fill in a screening questionnaire to assess the degree of neuropathy. Screening blood test (Complete blood picture) will be taken within 1 month of starting acupuncture. Eligible subjects will be enrolled into the study according to the inclusion and exclusion criteria. Any type of acupuncture or message in daily Traditional Chinese Medicine clinic will be prohibited during the trial once the subject is enrolled.

Subjects will be allocated to the 3 groups through computer generated randomization: acupuncture, sham acupuncture or the waiting-list (usual care) control group on a 1:1:1 ratio. Allocations will be kept within sealed opaque envelopes. Once a patient has been enrolled, an envelope is opened and the patient is then offered the allocated treatment regimen. Both the subjects (acupuncture and sham acupuncture group) and the gynaecological clinical research team responsible for the clinical care and neuropathy assessments will be blinded to the results.

Patients who are randomised to sham acupuncture or waiting-list control group will be offered the option of receiving 12 acupuncture treatments when they finish all study procedures.

Primary Outcome Measures

Name	Time	Method
Chemotherapy Induced Peripheral Neuropathy associated quality of life measured by Functional Assessment of Cancer Therapy / Gynecologic Oncology Group - Neurotoxicity subscale (FACT/GOG-NTX) total score	From enrollment to 6 weeks after end of treatment including: baseline at enrollment, after 3 weeks of treatment/enrollment, after 6 weeks of treatment (end of treatment)/ enrollment, and 6 weeks after end of treatment /12 weeks after enrollment	This questionnaire provides a targeted assessment of peripheral neuropathy symptoms. It consists of a total of 38 items on physical, social, emotional and functioning well-being with 11 questions focusing on neurotoxicity. This instrument is validated and has been used in Phase 3 clinical trials. The higher the score, the better the quality of life.

Secondary Outcome Measures

Name	Time	Method
The changes in quality of life assessed by European Organisation For Research And Treatment Of Cancer-Quality of Life-C30 (EORTC-QLQ-C30) questionnaires	From enrollment to 6 weeks after end of treatment including: baseline at enrollment, after 3 weeks of treatment/enrollment, after 6 weeks of treatment (end of treatment)/ enrollment, and 6 weeks after end of treatment /12 weeks after enrollment	Quality of life will be assessed by patient reported EORTC-QLQ-C30 questionnaires): C30 is a well validated instrument to assess quality of life in cancer patients. It consists of 30 items encompassing physical, emotional, social and functional aspects. Higher scores indicate better quality of life
The changes in quality of life assessed by European Organisation For Research And Treatment Of Cancer-Quality of Life-Chemotherapy Induced Peripheral Neuropathy 20 (EORTC-QLQ-CIPN20) questionnaires	From enrollment to 6 weeks after end of treatment including: baseline at enrollment, after 3 weeks of treatment/enrollment, after 6 weeks of treatment (end of treatment)/ enrollment, and 6 weeks after end of treatment /12 weeks after enrollment	Quality of life will be assessed by patient reported EORTC-QLQ-CIPN20 questionnaires: CIPN20 is a 20 items additional module to EORTC-QLQ-C30 focusing on Chemotherapy Induced Peripheral Neuropathy symptoms. Higher scores indicate better quality of life
assess the changes in light touch sensation by Semmes-Weinstein filaments test	From enrollment to 6 weeks after end of treatment including: baseline at enrollment, after 3 weeks of treatment/enrollment, after 6 weeks of treatment (end of treatment)/ enrollment, and 6 weeks after end of treatment /12 weeks after enrollment	For assessment the light touch sensation, the research assistant will perform Semmes-Weinstein filaments (SWM) test at the same time points as the patient's questionnaires (Baseline, Week 3, 6, 12). Each monofilament will be used for three consecutive times on the same point, and the participants are asked to provide information about their sense of touch with their eyes closed. The testing session starts using the thinnest monofilament, moving to a thicker one if the participant does not feel a monofilament.
assess the safety by National Cancer Institute-Common Terminology Criteria for Adverse Events (NCI-CTCAE) grading	From enrollment to 6 weeks after end of treatment including: baseline at enrollment, after 3 weeks of treatment/enrollment, after 6 weeks of treatment (end of treatment)/ enrollment, and 6 weeks after end of treatment /12 weeks after enrollment	Any adverse effects and their severity during treatment procedures including dizziness, nausea, vomiting, pain, discomfort, sweating, palpitations, bleeding and bruising will be assessed by CTCAE. The intervention will be discontinued if patients suffer from any serious adverse events (AEs). AE will be managed according to standard of care procedures.
assess the chemotherapy induced peripheral pain in numeric rating scale	From enrollment to 6 weeks after end of treatment including: baseline at enrollment, after 3 weeks of treatment/enrollment, after 6 weeks of treatment (end of treatment)/ enrollment, and 6 weeks after end of treatment /12 weeks after enrollment	Numeric rating scale represents a key element for measuring pain intensity and symptomatology. It ranges from 0 to 10. 0 means no pain and 10 means maximum pain.
Explore the acupuncture expectancy by Acupuncture expectancy scale (for acupuncture and sham acupuncture group)	At baseline and week 3 (after receiving treatment for 3 weeks)	In order to control the bias from placebo effect of acupuncture, acupuncture expectance scale will be used to measure the patients' expectations of positive outcomes from the treatment. It is a validated measurement with four items, with score ranging from 4 to 20
Explore the acupuncture credibility by Acupuncture credibility questionnaire (for acupuncture and sham acupuncture group)	At week 3 (after receiving treatment for 3 weeks)	Acupuncture credibility questionnaire is a questionnaire to control the bias from different patients' credibility of acupuncture practitioners. It is a validated assessment including 4 questions with score ranging from 0 to 6. 0 means minimum and 6 means maximum agreement of the item
Changes in inflammatory biomarkers	From enrollment to end of treatment including: baseline at enrollment, after 6 weeks of treatment (end of treatment)/ enrollment	Changes in inflammatory biomarkers after acupuncture will be explored. The BD cytometric Bead Array system (CBA) will be used to quantify the level of inflammation panel (IL10, IL12-p70, IL1β, IL6), Th1/Th2 panel (IL2, IL4, IL5, TNF, IFNγ), B cell activation panel (CD79b, BLNK, Btk, Syk, PLCγ), T cell activation panel (TCRz, SLP-76, ZAP70, Pyk2, Itk), and the Complements panel (C4a, C3a, C5a). The plasma level of CRP will be determined by ELISA assay. Fecal samples will be sent for fecal sequencing and profiling to explore the potential mechanisms of acupuncture effects.
