Clinical Trial Summary

Sickle cell disease (SCD) is characterized by an abnormal hemoglobin, the main protein in the red blood cell. From the first months of life, acute obstruction of the vessels of the microcirculation manifests as intense and unpredictable recurrent episodes of severe pain. In the Emergency Department (ED), patients presenting with a vaso-occlusive crisis (VOC) required a rapid evaluation and administration of pain relief therapies and hydration. this strategy is based on an intranasal (IN) administration of Sufentanil at the initial management of children with VOC, followed by morphine intravenous (IV) relay as soon as possible, compared to the usual care procedure with IV morphine as soon as possible. The hypothesis is that the use of this IN opioid at the beginning of the management of children with VOC can reduce the time before being pain relieved. Indeed, the IN administration make it easier and faster to administer.

Clinical Trial Description

Sufentanil is a powerful opioid analgesic used intravenously by emergency physicians for the sedation of intensive care, intubated and ventilated patients. It is therefore already present in the pharmacopoeia of emergencies. As the duration of action of inztranasal Sufentanil is too short to completely replace the IV morphine, a very promising approach would be to use it during the initial phase of the management of severe pain in children with painful sickle cell crisis while waiting for a venous access. The INVOPE trial is a phase III trial evaluating the intranasal sufentanil in sickle cell disease children with severe VOC. The INVOPE trial is a randomized controlled, multicenter, double blind, two parallel-group in a 1:1 ratio, placebo-controlled superiority trial comparing the analgesic efficacy of the sufentanil IN + standard care IV morphine / versus placebo IN + IV morphine as soon as possible. Children will be randomized in two groups: - Experimental group: IN Sufentanil procedure with IV administration of morphine as soon as possible - Control group : IN placebo IN procedure with IV administration of morphine as soon as possible The objective of this trial is to compare a procedure consisting in IN Sufentanil followed by IV morphine, when compared to IN placebo followed by IV morphine alone, in children with severe vaso-occlusive crisis. ;
