研究目的:

本实验旨在通过对比低剂量美沙酮(<30????∕??)联合其他阿片类药物与单独使用其他阿片类药物治疗难治性癌痛的安全性与有效性,探究低剂量美沙酮的应用是否能有效控制中晚期难治性癌症患者的疼痛,并探索其低剂量应用是否能降低美沙酮剂量依赖性心律失常及 QT 间期延长的风险 。  

Objectives of Study:

This trial aims to evaluate the safety and efficacy of low-dose methadone (<30 mg/day) combined with other opioids versus other opioids alone in managing refractory cancer-related pain. The study will investigate whether low-dose methadone effectively controls pain in patients with advanced refractory cancer and explore whether its low-dose application mitigates the risk of dose-dependent methadone-induced arrhythmias and QT interval prolongation.

干预措施:

患者入院后采用氢吗啡酮PCIA泵滴定,按前24h阿片用量1.2倍设置氢吗啡酮PCIA参数,根据疼痛评分(NRS)、不良反应调整。第1天:加用美沙酮,维持原药物剂量。第2-7天:根据PCIA用量调整美沙酮剂量(若DOSE≤3次/天则不加量),直至疼痛稳定,滴定期间美沙酮总量上限30mg/d。

干预措施代码:

Intervention:

Upon hospitalization, patients underwent pain titration using a hydromorphone PCIA pump. The pump parameters were set based on 120% of the prior 24-hour opioid consumption and were adjusted according to the Numeric Rating Scale (NRS) scores and the occurrence of adverse reactions. Day 1: Methadone was introduced as an adjunct therapy while maintaining the original hydromorphone dosage. Days 2-7: The methadone dose was adjusted based on the PCIA usage (no increase was made if the PCIA demand doses were <= 3 times/day). This titration continued until pain was stabilized, with a maximum total methadone dose of 30 mg/day during this period.

干预措施:

患者入院后采用氢吗啡酮PCIA泵滴定,按前24h阿片用量1.2倍设置氢吗啡酮PCIA参数,根据疼痛评分(NRS)、不良反应调整。第1天起:根据您PCIA 24h用量转换为口服阿片增量,逐日滴定至疼痛稳定(24h NRS≤3分、爆发痛≤3次/天、无不可耐受不良反应),至少观察7天。

干预措施代码:

Intervention:

Upon hospitalization, pain management was initiated with a hydromorphone Patient-Controlled Intravenous Analgesia (PCIA) pump. The pump parameters were set at 1.2 times the previous 24-hour opioid usage and were adjusted based on the patient's Numeric Rating Scale (NRS) scores and adverse reactions. Starting from Day 1: The 24-hour hydromorphone consumption via PCIA was converted into an incremental dose of oral opioids. This dose was then titrated daily until pain stabilization was achieved. The stabilization criteria were defined as: a 24-hour NRS score of <= 3, occurrence of breakthrough pain ≤ 3 episodes per day, and absence of intolerable adverse reactions. This stabilized state was maintained for at least an observation period of 7 days.

Data collection and Management (A standard data collection and management system include a CRF and an electronic data capture:

Trial data collection was performed using electronic case report forms (eCRFs). Data management in this study must ensure the authenticity, integrity, and confidentiality of clinical trial data. The data management process shall comply with relevant regulations such as ICH GCP and FDA 21 CFR Part 11, and guarantee the traceability of all clinical trial data. The Case Report Form (CRF) shall be faithfully completed by the investigator or their designee with reference to the source medical records and must not be altered arbitrarily. Any necessary revisions shall be made in accordance with the CRF completion guidelines, accompanied by the signature (or initials) of the person making the change and the date of modification. The investigator at each site is responsible for verifying the accuracy and authenticity of all information in every CRF, signing and dating the form upon confirmation. Upon completion, the original CRF shall be promptly collected and transported to the Data Management Department by the clinical research associate (CRA). The investigator, CRA, and data management personnel must cross-check the collected CRFs for accuracy. Once confirmed, all parties shall sign the CRF transmittal form. Any issues identified during this process should be immediately communicated to the CRA, who will request clarification from the investigator.
