About

This study is a single-dose, open-label, 2-cycle crossover design, comparing the pharmacokinetic parameters and safety of Inhaled Fentanyl Aerosol and intravenous fentanyl injection.

Full description

Consenting patients who met inclusion and exclusion criteria were allowed to enter the study. The subjects will be randomly assigned (1:1) to receive an intravenous bolus (5 seconds) of 25μg fentanyl injection in the first cycle, and after a 2-week washout period, to receive a single dose of 25μg inhaled fentanyl aerosol through the Staccato delivery system in the second cycle; or to receive the same treatment in the opposite order.

Enrollment: 100 estimated patients

Sex: All

Ages: 18 to 55 years old

Volunteers: No Healthy Volunteers

Inclusion criteria

1. Volunteer to participate, understand and sign the informed consent form before conducting the evaluation project;

2. Male or female subjects, aged between 18 and 55, including 18 and 55 years old;

3. plan to receive radiotherapy and / or systemic chemotherapy within 14 days before the first administration or during the study period (except for patients who receive immune checkpoint inhibitors or targeted drug maintenance therapy that is not a CYP3A4 inhibitor / inducer and whose condition is stable);
4. within 14 days before the first administration, the patient had received any monoamine oxidase (MAO) inhibitors (such as phenelzine, isocarbazine, chlorogiline, toloxadone, moclobemide, selegiline, rasagiline, etc.); Or have used CYP3A4 inhibitors (such as indinavir, nelfinavir, ritonavir, clarithromycin, itraconazole, nefazodone, ketoconazole, telithromycin, arepitan, erythromycin, fluconazole, grapefruit, verapamil, diltiazem, cimetidine, etc.) or CYP3A4 inducers (such as phenobarbital, carbamazepine, efavirenz, glucocorticoids, modafinil, nevirapine, oxcarbazepine, phenytoin, pioglitazone, rifabutin, rifampicin);
5. have participated in other clinical studies or received surgical treatment within 30 days before the screening period, or have surgery plans during the study period;
