Lidocaine 5% Plasters (Versatis® 5%) in Pediatric Neuropathic Pains and Vasoocclusive Sickle Cell Crisis Pains

Overview

Lidocaine 5% plaster (VERSATIS® 5%) showed its efficacy and safety in the post-herpetic zoster adult pains. This treatment is recommended in first intention in adult neuropathic pains with allodynia.

The purpose of this study is to assess efficacy and safety of lidocaine 5% plaster (VERSATIS® 5%) in the pediatric neuropathic pains and vasoocclusive sickle cell crises pains.

Detailed Description

Pediatric neuropathic pain are infrequent. It's difficult to estimate the prevalence. It may result from several causes : infectious (post-herpetic neuropathy), traumatic (tumor or Positional)or toxic (chemotherapy or radiotherapy). They are often associated with malignant pediatric disease.

These pains are spontaneous, continuous or intermittent, as type of burns or electric shocks or abnormal skin sensation (hyperesthesia or allodynia). Treatment is the same as in adults: antiepileptic or neuroleptics, sometimes associated with analgesic (level 2 or 3).

Lidocaine 5% plaster are used in adults as first line of treatment to reduce post-herpetic neuropathic pain, especially in cases of mechanical allodynia. These plasters are indicated for the symptomatic treatment of post-herpetic neuropathic pain.

Each plaster contains 700 mg of lidocaine. It must be applied on the painful area once daily for a maximum period of 12 hours per 24 hours.

The primary endpoint is to evaluate the efficacy of lidocaine 5% plaster (VERSATIS 5%) after 12 hours on reducing of pure or mixed neuropathic pain and on reducing of vasoocclusive sickle cell pain, localized, superficial, in child, adolescent and young adult.

The secondary endpoint are:

1. to evaluate the efficacy of lidocaine 5% plaster (VERSATIS 5%) after 6 hours on reducing of pure or mixed neuropathic pain and on reducing of vasoocclusive sickle cell pain, localized, superficial, in child, adolescent and young adult.

2. to evaluate safety of lidocaine 5% plaster (VERSATIS® 5%) in these same indications.

Interventions

Clinical Trial Outcome Measures

Primary Measures

  • Lidocaine 5% plaster efficacy between t0 and t12
    • Time Frame: 12 hours
    • Rate of patients with a decrease of at least 2 points in pain score (at least 2 of 3 consecutive days) measured by self-assessment on a visual analogue scale (VAS) graded from 0 to 10 (0 = absence pain and 10 = maximal pain ), between start of treatment(t0) and a measure carried out 12 hours later (t12).

Secondary Measures

  • Lidocaine 5% plaster efficacy between t0 and t6
    • Time Frame: 6 hours
    • Rate of patients with a decrease of at least 2 points in pain score (at least 2 of 3 consecutive days) measured by self-assessment on a visual analogue scale (VAS) graded from 0 to 10 (0 = absence pain and 10 = maximal pain ), between start of treatment(t0) and a measure carried out 6 hours later (t6).
  • Lidocaine 5% plaster safety
    • Time Frame: 72 hours
    • Rate of patients with local and/or general adverse event as graded using NCI-CTCAE V4.0
