Brief Summary:
The purpose of the study is to determine the clinical efficacy and safety of Maxigesic IV, acetaminophen IV, Ibuprofen IV versus placebo IV for the treatment of acute postoperative pain after bunionectomy

Condition or disease Intervention/treatment Phase
Post Operative Pain Drug: Maxigesic IV Drug: IV Acetaminophen Drug: IV Ibuprofen Drug: Placebo IV Phase 3

Detailed Description:

AFT Pharmaceuticals Ltd. has been developing a fixed-dose combination of acetaminophen 1000mg and ibuprofen 300mg/100mL solution for infusion (Maxigesic IV) for the temporary relief of postoperative pain, when administration by intravenous route is clinically justified by an urgent need to treat pain or hyperthermia and/or when other routes of administration not possible.

A phase 3 efficacy study (AFT-MXIV-07) is proposed to determine the analgesic effects of the fixed dose combination product Maxigesic IV versus its individual components (acetaminophen IV and ibuprofen IV) and placebo in participants with acute post-operative pain after bunionectomy.

The primary efficacy objective is to determine the efficacy of Maxigesic IV, acetaminophen IV, Ibuprofen IV versus placebo IV as measured by the summed pain intensity difference (SPID) (calculated as a time-weighted average) over 0-48 hours (SPID-48) after time 0.

Other secondary efficacy endpoints are:

VAS Pain intensity difference (PID) at each scheduled assessment time point after Time 0 VAS Pain intensity score at each scheduled assessment time point VAS SPID over 0 to 6 hours (SPID-6), over 0 to 12 hours (SPID-12), and over 0 to 24 hours (SPID-24) after Time 0

Summed pain relief (TOTPAR) (calculated as a time-weighted average) over 0 to 6 hours (TOTPAR-6), over 0 to 12 hours (TOTPAR-12), over 0 to 24 hours (TOTPAR-24) after Time 0, and over 0 to 48 hours (TOTPAR-48) after Time 0

Time to onset of analgesia (measured as time to perceptible pain relief confirmed by meaningful pain relief) using the two-stopwatch method Pain relief score on a 5-point categorical scale at each scheduled time point after Time 0

Peak pain relief

Time to peak pain relief

Time to first perceptible pain relief

    Hormonal methods such as oral, implantable, injectable, or transdermal contraceptives for a minimum of 1 full cycle (based on the subject's usual menstrual cycle period) before study drug administration.

    Total abstinence from sexual intercourse since the last menses before study drug administration through completion of final study visit.

  10. Is willing and able to comply with study requirements (including diet, alcohol, and smoking restrictions), complete the pain evaluations, remain at the study site for approximately 72 hours, and return for follow-up 7 ± 2 days after surgery.

Exclusion Criteria:

  1. Has a known history of allergic reaction or clinically significant intolerance to acetaminophen, aspirin, opioids, or any nonsteroidal anti-inflammatory drugs (NSAIDs, including ibuprofen); history of NSAID-induced bronchospasm (subjects with the triad of asthma, nasal polyps, and chronic rhinitis are at greater risk for bronchospasm and should be considered carefully); or hypersensitivity, allergy, or significant reaction to sulfa (including sulfonamide) medicines, ingredients of the study drug, or any other drugs used in the study including anesthetics and antibiotics that may be required on the day of surgery.
  2. Has experienced any surgical complications or other issues that, in the opinion of the investigator, could compromise the safety of the subject if he or she continues into randomized treatment period or could confound the results of the study.
  3. Has known or suspected history of alcoholism or drug abuse or misuse within 2 years of screening or evidence of tolerance or physical dependence before dosing with study drug.
  4. Has any clinically significant unstable cardiac, respiratory, neurological, immunological, hematological, or renal disease or any other condition that, in the opinion of the investigator, could compromise the subject's welfare, ability to communicate with the study staff, or otherwise contraindicate study participation.

  6. Has a history or current diagnosis of a significant psychiatric disorder that, in the opinion of the investigator, would affect the subject's ability to comply with the study requirements.
  7. Has tested positive either on the urine drug screen or on the alcohol breathalyzer test. Subjects who test positive at Screening only and can produce a prescription for the medication from their physician may be considered for study enrolment at the discretion of the investigator.

  10. Is considered by the investigator, for any reason (including, but not limited to, the risks described as precautions, warnings, and contraindications in the current version of the Investigator's Brochure for IV Maxigesic®), to be an unsuitable candidate to receive the study drug.
  11. Is receiving systemic chemotherapy, has an active malignancy of any type, or has been diagnosed with cancer within 5 years before Screening (excluding treated squamous or basal cell carcinoma of the skin).
  12. Is currently receiving anticoagulants (eg, heparin or warfarin).

Aspirin at a daily dose of ≤ 325 mg is allowed for cardiovascular prophylaxis if the subject has been on a stable dose regimen for ≥ 30 days before Screening and has not experienced any relevant medical problem.
  16. Has been treated with agents that could affect the analgesic response (such as central alpha agents [clonidine and tizanidine], neuroleptic agents, and other antipsychotic agents) within 2 weeks before dosing with study drug.
  17. Has a significant renal or hepatic disease, as indicated by clinical laboratory assessment (results ≥ 3 times the upper limit of normal [ULN] for any liver function test, including aspartate aminotransferase [AST], alanine aminotransferase [ALT], and lactate dehydrogenase, or creatinine ≥ 1.5 times the ULN).
  18. Has any clinically significant laboratory finding at Screening that, in the opinion of the investigator, contraindicates study participation.
