Hernia, Inguinal Flat Foot | Drug: Chloroprocaine 1% Injectable Solution Drug: Chloroprocaine 2% Injectable Solution | Phase 2 |
Randomized, multi-center, double-blind, two-armed, parallel active groups, prospective trial, to evaluate, in pediatric population undergoing Flat Foot surgery or Inguinal hernia repair, the efficacy and safety of chloroprocaine 1% and 2% for peripheral nerve block (PNB) based on concentration-response relationships. The present protocol is part of an extensive Pediatric Investigational Plan (PIP) which has been submitted to the Paediatric Committee (PDCO) of the European Medicine Agency (EMA)in the contest of the marketing authorization application of chloroprocaine use for perineural block. The PDCO has adopted a positive opinion on both the PIP and the present clinical protocol.
Chloroprocaine Hydrochloride 1% Sintetica is currently marketed in 9 European countries as intrathecal (spinal) anesthetic in adults where the planned surgical procedure is not expected to exceed 40 minutes. Since 2015, the Marketing Authorization in Switzerland has been extended to chloroprocaine HCl 20 mg/mL and 30 mg/mL solutions for injection, for local anesthesia by infiltration, for PNB and epidural block, respectively. Regional analgesia, and specifically PNB, is an acceptable means of providing intraoperative anesthesia and postoperative analgesia in neonates, infants, and children while decreasing the use of systemic opioids and avoiding opioid-related adverse effects. With the advent of ultrasound and improvements in equipment in the last decade, the utilization of PNB in children has increased tremendously.
Flat Foot and inguinal hernia repair have been considered the ideal surgeries for testing the clinical efficacy and safety of chloroprocaine since they are short procedures with low postoperative pain that only require a short- to intermediate-acting agent. The study consists of a treatment period of 1 day and of a single perineural injection, administered through ultrasound-guided technique in order to avoid the risk of chloroprocaine IV injection. A total of 174 (87 per treatment group, allocated to 1% or 2% arm in a ratio of 1:1) male and female paediatric patients (age range from birth to <18 years) undergoing Flat Foot surgery or Inguinal hernia repair, planned for peripheral nerve block anaesthesia and equally distributed within the two surgical procedures.

- Overall proportion of patients, in each of the two dosage level groups, not requiring rescue anesthesia during surgery. [ Time Frame: Visit 2 (Day 1; surgery/discharge) ]The primary efficacy endpoint of the study will be represented by the overall proportion of patients, in each of the two dosage level groups, not requiring rescue anesthesia during surgery.
- Proportion of patients, in both of the two dosage level groups, not requiring rescue anaesthesia (fentanyl) during the two surgical procedures separately [ Time Frame: Visit 2 (Day 1; surgery/discharge); FU phone call I( 24 hrs from Visit 2); FU phone call II (7 days from Visit 2) ]Proportion of patients, in both of the two dosage level groups, not requiring rescue anaesthesia (fentanyl) during the two surgical procedures separately; Time to onset of sensory block, defined as the time period from completion of the injection (time 0 min) to the achievement of complete sensory block, assessed by pinprick test associated with heart rate measurement, and evaluated for both surgeries; Time to regression of motor block evaluated in 'calcaneo stop' surgery only and assessed by a grade I of the standard Bromage scale (i.e. free movement of legs and feet). Pain intensity evaluated five times in the first 3 hours after patient's awakening andduring the home discharge visit (V2). The technique and appropriate scale for pain measurement are age-dependent therefore, different tools will have to be used for the evaluation: COMFORT scale for patients <2 months of age; FLACC scale for patients aged _ 2 months _ 6 years; Wong-Baker scale for patients over 6 years of age
