Electroacupuncture for the Prevention of Chemotherapy-induced Nausea and Vomiting in Patients With Breast Cancer

Официальное название

A Study on Electroacupuncture Combined With Olanzapine-contained Four-drug Antiemetic Therapy for the Prevention of Highly Emetogenic Chemotherapy-induced Nausea and Vomiting in Patients With Breast Cancer (ECO Study)

Обзор

This randomized controlled phase III trial aims to evaluate the use of electroacupuncture in combination with olanzapine-containing standard quadruple antiemetic drugs for the treatment of nausea and vomiting induced by highly emetogenic chemotherapy (HEC) in patients with breast cancer. Furthermore, it will analyze the relationship between single nucleotide polymorphism and electroacupuncture treatment for chemotherapy-induced nausea and vomiting.

Подробное описание

This study is a parallel-group, blinded (participants, evaluators, and statisticians), randomized controlled trial exploring the effectiveness of electroacupuncture combined with standard quadruple antiemetic drugs for breast cancer patients undergoing HEC. Both groups will receive Olanzapine, Neurokinin-1 receptor antagonists (NK-1RAs), serotonin receptor antagonists \[5HT3RA\], and dexamethasone at the start of HEC on Day 1. Electroacupuncture or sham acupuncture will be randomly administered to each group. Participants will document all instances of nausea and vomiting and note the use of rescue antiemetic medications. Blood samples will be collected and analyzed to investigate whether genetic polymorphisms can predict electroacupuncture outcomes in breast cancer patients undergoing HEC. Primary and secondary outcomes as well as adverse events will be assessed.

Вмешательства

• Устройство Electroacupuncture
  The acupuncturists will insert needles into the acupoints and manipulate the needles until"de qi"sensation is achieved and reported by the participants. Electrical stimulation will be delivered for 30 minutes at alternating frequencies of 2/10Hz.
• Препарат Standard antiemetic treatment
  Olanzapine 2.5 mg per day orally on days 1 through 4 + fosaprepitant 150 mg intravenous (IV) or aprepitant injectable emulsion 130 mg IV + palonosetron 0.25 mg IV or ondansetron 8 mg IV or tropisetron 5 mg IV (the previously mentioned medication, which includes fosaprepitant or aprepitant combined with palonosetron or ondansetron or tropisetron, can also be taken orally in a fixed combination of netupitant (300 mg) and palonosetron (0.50 mg))+ dexamethasone 10 mg IV 30 minutes prior to chemother
• Устройство Sham electroacupuncture
  The sham acupuncture comprised a core standardized prescription of minimally invasive, shallow needle insertion using thin and short needles at body locations not recognized as true acupuncture points and are deemed to not belong to traditional Chinese meridians and have no therapeutic value. Participants will receive minimal acupuncture treatment without electrical stimulation at the same time as the intervention group.Care was taken to avoid "de qi" sensation.
