Safety and Efficacy of Methoxyflurane for Treatment of Incident Pain

January 27, 2010 updated by: Medical Developments International Limited

A Phase IV, Randomized, Double Blind, Single Centre, Placebo Controlled Study to Assess the Safety and Efficacy of Methoxyflurane [Penthrox] for the Treatment of Incident Pain in Participants Undergoing a Bone Marrow Biopsy Procedure

This study aims to provide further supportive evidence that Methoxyflurane, a potent analgesic, administered using the Penthrox Inhaler is safe and efficacious in adult participants, specifically those who experience incident pain associated with a planned bone marrow biopsy.

  • Anticipated life expectancy of at least 1 month

Pre-Exclusion Criteria:

  • Subjects with a clinical condition that may, in the opinion of the investigator, impact on the subject's ability to participate in the study, or on the study results
  • Participants who have had IV sedation/opioid on previous BMB and who wish to receive IV sedation/opioid on this occasion or who in the opinion of the BMB operator would be advised to receive IV sedation/opioid on this occasion

  • Concomitant use of nephrotoxic agents such as gentamicin
  • Uncontrolled INR (>4)
  • Personal or familial hypersensitivity to fluorinated anaesthetics
  • Personal or familial malignant hyperthermia
  • Respiratory rate of less than 10 per minute
  • Has previously received methoxyflurane
  • Known pre-existing renal or hepatic impairment
  • Compromised Renal Function (creatinine ≥ 1.5 x ULNR)
  • Compromised Liver Function (bilirubin ≥ 2.5 x ULNR)

Exclusion Criteria:

  • Premedication with anxiolytic (e.g. midazolam, diazepam)
  • Dosed with breakthrough dose of analgesic that may contribute to control of pain during the planned procedure
