Keywords
Orally, IV PCA with continuous + bolus dose, IV PCA with bolus-only dose
Brief summary
Based on the previous HMORCT09-2, the results show that IV PCA for analgesia maintenance improvements control of severe cancer pain after successful titration. Therefore, a study is planned to further explore the difference of efficacy and safety between PCA with continuous + bolus dose versus bolus-only.
Interventions
Intravenous PCA with hydromorphone after successful titration of 24 hours.the PCA setting: 1) continuous dose (dose/hours) = the total dosage of hydromorphone in the previous 24 hours/24; 2) bolus dose = 10-20% of the total dosage of hydromorphone in the previous 24 hours; 3) lockout time = 10 minutes; 4)Evaluate every 24 hours and PCA parameters were adjusted according to the dose of the previous day.
Swift to sustained-release morphine orally as background dose with immediate release morphine orally for breakthrough pain after successful titration of 24 hours. Administration of morphine orally 1) Sustained-release morphine orally (dose/12 hours) = the total equianalgesic of the previous 24 hours/2×75% for day 1; 2)the total equianalgesic of the previous 24 hours/2 for day 2 ; 3)Evaluate every 24 hours and the dose for the next day is adjusted according to the dose of the previous day;4) Immediate release morphine orally = 10-20% of the total equianalgesic of the previous 24 hours;

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| 3DNRS (3-day average Numeric Rating Scale) | up to 4 days | The Numerical Rating Scale (NRS, a score of 0 means no pain and 10 means the most severe) is used to assess the severity of pain. NRS of 24 hours is assessed every day. 3DNRS is a sum of average NRS of Day 1 (D 1) to Day 3 divided by 3 (the day of titration is defined as D0, the first day after titration is defined as D1, the second day after titration is defined as D2, and so on). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Number of patients with an average NRS pain score > 6 | up to 7 days | The Numerical Rating Scale (NRS, a score of 0 means no pain and 10 means the most severe) is used to assess the severity of pain. |
| Number of patients with an average NRS pain score >3 | up to 7 days | The Numerical Rating Scale (NRS, a score of 0 means no pain and 10 means the most severe) is used to assess the severity of pain. |
| Maximum NRS (Days 1 to 6) | up to 7 days | Maximum NRS score (Days 1 to 6) |
| Daily frequency and duration of breakthrough cancer pain | up to 7 days | Daily frequency and duration of breakthrough cancer pain (defined as transient pain exacerbation \[NRS ≥4\]) |
| Daily equivalent morphine consumption | up to 7 days | Daily equivalent morphine consumption |
| Adverse events | up to 8 days | assessed by NCI-CTCAE v5.0 |
| Improvement in physical symptoms and overall well-being | up to 7 days | assessed by Chinese version of the Edmonton Symptom Assessment System. |
| Patient Satisfaction Score | up to 7 days | The satisfaction score of the patients to analgesia was evaluated by 10-point scale: 0 points for dissatisfaction, 10 points for very satisfied, the higher the score, the higher the satisfaction. |
| Daily avNRS score of days 1 to 6 | up to 7 days | Daily average NRS pain score of days 1 to 6 |
