Clinical Trial Summary

The LOLIPOP Trial is a large (n=4,300 patients) pragmatic, international, multicentre, prospective, randomised, double blind, placebo-controlled, parallel assessment, safety and effectiveness superiority study.

Description:

The Trial's purpose is to evaluate the effectiveness of lidocaine infusions commenced during surgery and extending up to 24 hours postoperatively, on the incidence of moderate or severe chronic post-surgical pain (CPSP) detected one year following surgery in female patients undergoing elective breast cancer surgery. The trial has 90% power to detect a clinically meaningful (25%) reduction in the incidence of the primary outcome. Secondary outcomes include safety events, analgesic efficacy (pain scores and opioid consumption), neuropathic characteristics of CPSP, and psychological and quality of life outcomes.

Intervention

Drug:
• lidocaine 2% and 10%
Lidocaine infusion: Commencing with an intravenous bolus after induction of anaesthesia, 0.125 ml/kg of lean body weight (LBW) of 2% lidocaine (2.5 mg/kg).* Followed by a 2% lidocaine intravenous infusion for the duration of surgery, 0.1665 ml/kg/h of LBW (3.33 mg/kg/hr).* A post-operative subcutaneous 0.0222 ml/kg/hr of LBW 10% lidocaine infusion for up to 24 hours thereafter (2.22 mg/kg/hr). Dosage will be capped at a maximum lean body weight of 68kg. *Day-case surgery receives intraoperative bolus and intraoperative infusion only
• Placebo
Placebo infusion: Commencing with an intravenous bolus after induction of anaesthesia, 0.125 ml/kg of lean body weight (LBW) of 0.9% Saline solution.* Followed by a 0.9% Saline solution intravenous infusion for the duration of surgery, 0.1665 ml/kg/h of LBW (3.33 mg/kg/hr).* A post-operative subcutaneous 0.0222 ml/kg/hr of LBW 0.9% Saline solution infusion for up to 24 hours thereafter (2.22 mg/kg/hr). Dosage will be capped at a maximum lean body weight of 68kg. *Day-case surgery receives intraoperative bolus and intraoperative infusion only
