简要总结
The goal of this clinical trial is to evaluate the analgesic activity of PF614 (an oral oxycodone prodrug extended-release analgesic) for control of postsurgical pain in subjects scheduled for abdominoplasty surgery. The main question to be answered is:
• To assess the analgesic efficacy of PF614 compared to placebo in subjects with moderate to severe pain following abdominoplasty.
Participants will be asked to take oral blinded doses of study medication at about one hour before surgery starts, and then every 12 hours after surgery for up to 4 days.
Participants will be asked to:
- Rate their pain on a 0-10 numerical rating scale (NRS) at various timepoints up to 5 days following surgery;
- Tell us about the need for rescue medication if they continue to have moderate-to-severe pain;
- Tell us about any side effects or adverse effects that they may experience to help us understand the safety and tolerability of the test medications;
- Provide periodic blood samples to help us understand how much study drug is in their system.
Participants will stay in a clinic setting and be monitored for safety for 5 days following surgery. We anticipate that participants will be discharged on Day 5, pending medical review, and then keep a diary to record study-related pain and adverse effects for an additional 2-4 days after discharge.
详细描述
This will be a Phase 3, multicenter, randomized, double-blind, placebo-controlled study to evaluate the efficacy and safety of PF614 in the treatment of moderate to severe acute postoperative pain following abdominoplasty. The study will be conducted in 4 phases: Screening, Treatment, Outpatient and Follow-up.
Screening Phase Prospective participants will complete a standard medical screening within 28 days of the abdominoplasty procedure. At Screening, participants will provide written informed consent to participate in the study before any protocol-specified procedures or assessments are conducted.
Treatment Phase The Treatment Phase will begin on the day of the abdominoplasty procedure (Day 1) and will end on postoperative Day 5. Participants will be admitted to the study center on the morning of the scheduled procedure and will be confined throughout the Treatment Phase (5 days, 4 nights).
Days 1-4 (0-72 hours): Randomized Treatment Period Following admission to the study center, presurgical procedures will include participant training on pain intensity assessments, which will be administered as 11-point numerical rating scales (NRS). Participants who continue to meet all study entry criteria will be randomized prior to the abdominoplasty procedure in a 1:1:1:1 ratio to 1 of 4 treatment groups.
Treatment groups will include the following doses: PF614 25 mg, PF614 37.5 mg, PF614 50 mg, and Placebo.

- •Participant must have physical status rated as I-II on the American Society of Anesthesiologists rating scale.
- •Participant must have a body mass index (BMI) within 18.0 to 32.0 kg/m2, inclusive (minimum weight of at least 50.0 kg).
- •If female, participant must be either not of childbearing potential (defined as postmenopausal for at least 1 year and confirmed with follicle stimulating hormone [FSH] >40 mIU/mL as deemed necessary by the investigator, or surgically sterile [bilateral tubal ligation, bilateral oophorectomy, or hysterectomy]) or participant must use a medically acceptable method of birth control (oral or transdermal hormonal contraceptives; vaginal ring; contraceptive implant or injection; intrauterine contraceptive system [with or without hormone]; condom and spermicidal foam; heterosexual abstinence; or sterilization of partner) from 30 days prior to Screening through 90 days after the last study drug administration. Heterosexual abstinence is considered to be a highly effective method only if the participant agrees to refrain from heterosexual intercourse during the entire period from 30 days prior to Screening to 90 days after the last study drug administration.
- •If male, participant must agree to use medically acceptable methods of contraception (diaphragm/sponge/condom with spermicide, vasectomy); female sexual partners of childbearing potential must be using and willing to continue using medically acceptable contraception (i.e., oral or transdermal hormonal contraceptives, vaginal ring, contraceptive implant or injection intrauterine contraceptive system [with or without hormone]) from Screening and for at least 90 days after the last study drug administration.
- •Must be able to speak, read, and understand English or Spanish sufficiently to allow completion of all study assessments.
- •Participant must be willing and able to follow study instructions and be likely to complete all study requirements.
