Clinical Trial Summary

This study is to evaluate the efficacy and safety of a titration method by selects 10 mg control-released (CR) oxycodone tablet as background drug in combined with immediate-released (IR) oxycodone, compared to conventional titration method with immediate-released (IR) oxycodone in patients with moderate to severe cancer pain in Taiwan.

Description:

This is an interventional, open label, randomized controlled study carrying in multi-centers. Eighty opioid-naive patients with moderate to severe cancer pain (≥ 4) in outpatient department (OPD), who agreed and signed informed consent will be randomly assigned in a 1:1 ratio to receive CR + IR oxycodone or conventional IR oxycodone groups. The study is to compare the titration efficacy and safety of CR with IR oxycodone (experimental group) comparing IR oxycodone (control group) in cancer patients suffered with moderate to severe pain. The study last 14 days. Patients begin the study by the first day visit of the clinic and received the study medication (Baseline). Following visits on cycle 1 (day 3 or 4 depends on the available clinics), cycle 2 (day 7±1), cycle 3 (day 10±1), and cycle 4 (day 14±1). In the experimental group, 10 mg CR oxycodone tablet will be selected as background dose of titration, and patients will be administered once every 12 hrs. Meanwhile, the titration with IR oxycodone will be added according to the pain intensity, e.g. if patient receiving 6 tablets of 10 mg CR oxycodone (giving in Q12H frequency for 3 days), 12 capsules of 5mg IR oxycodone will be dispensed for managing acute pain (rescue use) for the first cycle. In the control group, the conventional titration with IR oxycodone will be conducted according to pain intensity, using 5 mg as initial dose, e.g. 12 capsules of 5mg IR oxycodone (giving in Q6H frequency for 3 days), 12 capsules of 5mg IR oxycodone will be dispensed for rescue use upon to the first cycle. Patient will record their pain score (4 times in Q6H frequency and before taking the drug), 24hr total dose (total tablets/capsule number), number of breakthrough pain and PRN time and dosage used onto the patient diary. The background dose of each patient will be titrated after cycle 1 by investigators. Titration cycles will be recorded and evaluated pain assessments on cycle 2 (day 7±1), cycle 3 (Day 10±1), cycle 4 (day 14±1). During study, the study nurse will follow patient's daily records, drug use condition every second day by telephone or other contact methods to keep close monitor of patient's condition. The telephone contact for cycle 1 and cycle 3 is acceptable for this study. If the telephone contact is conducted for patient, the 1-week quantities of oxycodone should be dispensed to patient.

The safety for individual patient will be followed during study up to end of treatment (EOT) or early termination (ET). All adverse events (AE(s)) and serious adverse events (SAE(s)) occurred during the study period will be followed until resolution or the event is considered stable.

Eligibility

Inclusion Criteria:

3. ECOG = 2

4. Opioid-naive patients who are not administrated any strong opioid for at least one month prior to the index treatments, who currently with poor pain control and intended to be treated for pain relief with strong opioids. The FDA identifies opioid-naive as who not receiving the following treatment for a week or longer of strong opioids:

1) = 60 mg of morphine daily 2) =25 mcg transdermalfentanyl/hour 3) = 8 mg of oral hydromorphone daily or 4) an equianalgesic dose of another opioid

5) Patients who will not be treated with radiotherapy within 7 days prior to randomization and during study

6) Patients who need chemotherapy, long term administration of hormone, targeted therapy, or bisphosphonates therapy should undergo a stable anti-tumor therapy prior to randomization.

7) Patients or his/her caregivers who are able to fill out the diary and questionnaire forms

Exclusion Criteria:

1. Patients diagnosed with non-cancer pain or unexplained pain

2. Patients suffered with post-op pain

3. Patients who cannot be applicable for oral administration

4. Patients who have severe constipation defined by CTCAE grade 3 and above

5. Patients with any disease that may easily lead to respiratory depression

6. Monoamine oxidase inhibitor (MAOI) was administrated one week before randomization

7. There are abnormal lab results, with obvious clinical significance, such as the creatinine = 2 fold of upper limit of normal value, or ALT or AST = 2.5 fold of upper limit of normal value (= 5 fold, to the patients with liver metastasis or primary liver cancer), or liver function of Child C grade

8. Patients who have potential risk for surgical operation, which may lead to gastrointestinal stenosis, blind loop or gastrointestinal obstruction; or patient is unable to effectively absorb oral medication through gastrointestinal tract

9. Patients who are drug or alcohol abuse

10. Patients with moderate to severe psychiatric problems

11. Patients who have hypersensitivity to oxycodone

12. Patients who are pregnant or lactating

13. Patients who are clinically unstable or have a life expectancy of less than three months making completion of the trial unlikely
