Brief summary

Study to evaluate the overall performance of the Zalviso System™ (sufentanil sublingual tablet system) 15 mcg

Detailed description

320 adult postoperative in-patients, who met all study entry requirements, and were expected to require opioid analgesia for at least 24 hours, and up to 72 hours, after surgery were enrolled. Patients used the Zalviso™ (sufentanil sublingual tablet system) 15 mcg to self-administer a tablet of study drug as needed for pain. The System was evaluated for usability and functionality for up to 72 hours.

Interventions

DRUGZalviso™ 15 mcg

Zalviso™ (sufentanil sublingual tablet system) 15 mcg. Tablets to be self-administered by the patient as needed for pain, no more than every 20 minutes, for 24 hours and up to 72 hours

Inclusion criteria

1. Male or female patients who were 18 years of age or older. 2. Patients who were scheduled to undergo surgery under general or spinal anesthesia that does not include intrathecal opioids during the operation. 3. Patients classified as American Society of Anesthesiologists (ASA) class I - III (Appendix I). 4.

Acceptable methods of birth control included oral or transdermal contraceptives, condom, spermicidal foam, intrauterine device (IUD), progestin implant or injection, abstinence, vaginal ring, or sterilization of partner. The reason for non-child bearing potential, such as bilateral tubal ligation, bilateral oophorectomy, hysterectomy, or postmenopausal for \> 1 year, was specified. Patients using hormonal forms of contraception were also willing to use a barrier method of contraception from screening through 30 days following the study period. 5. Post-surgical patients who had been admitted to the PACU, and were expected to have acute pain requiring opioids for 24 - 72 hours after surgery.

Exclusion criteria

1. Patients who had taken an opioid for more than 30 consecutive days, at a daily dose of 15 mg or more of morphine (or equivalent), within the past 3 months prior to surgery (e.g. more than 3 doses per day of Vicodin®, Norco®, Lortab® with 5 mg hydrocodone per tablet). 2. Patients who were currently taking monoamine oxidase inhibitors (MAOIs) or had taken MAOIs within 14 days of the first dose of study drug. 3. Patients with current sleep apnea that had been documented by a sleep laboratory study or were on home continuous positive airway pressure (CPAP). 4. Patients with an allergy or hypersensitivity to opioids. 5. Patients who were currently taking monoamine oxidase inhibitors (MAOIs) or had taken MAOIs within 14 days of the first dose of study drug. 6.

The time-weighted SPID48 is the time-weighted summed PID over the 48-hour study period. A negative score indicates an increase in pain intensity and a higher score indicates a greater decrease in pain intensity.The scores ranged from -144 to 408.
Time-weighted Summed Pain Intensity Difference (SPID) Over the 72-hour Study Period (SPID-72) Study PeriodUp to 72 hoursThe pain intensity difference (PID) at each evaluation time point after the dose of study drug is the difference in pain intensity at the specific evaluation time point and baseline pain intensity \[PID(evaluation time after the first dose) = PI(baseline) - PI(evaluation time after the first dose)\].

Total Amount of Supplemental Morphine (mg) UtilizedUp to 72 hoursSupplemental opioid medication (2 mg IV morphine) was allowed in the first 30 minutes after the first on-demand dose of study drug had been administered, if necessary, to keep a patient comfortable. Otherwise, supplemental opioid medication (2 mg IV morphine, no more frequently than hourly) was allowed for pain due to ambulation or with the initiation of passive range of motion therapy throughout the remainder of the study.

Time-weighted Summed Pain Intensity Difference (SPID) Over the 24-hour Study Period (SPID24)

The pain intensity difference (PID) at each evaluation time point after the dose of study drug is the difference in pain intensity at the specific evaluation time point and baseline pain intensity \[PID(evaluation time after the first dose) = PI(baseline) - PI(evaluation time after the first dose)\]. A pain intensity score ranging from 0 (no pain) to 10 (worst possible pain) is obtained at baseline and at protocol-specified time points throughout the 24 hour period. The time-weighted SPID24 is the time-weighted summed PID over the 24-hour study period. A negative score indicates an increase in pain intensity and a higher score indicates a greater decrease in pain intensity.The scores ranged from - 72 to 204.
