Clinical Trial Summary

Sickle cell anaemia is an inherited blood disorder which results in abnormal sickle shaped red blood cells which do not fit well through small blood vessels. These blockages prevent oxygen (in blood) from reaching different parts of the body resulting in painful crisis. This study will compare the effectiveness of two types of pain medication, one given through a vein and one squirted up the nose.

Description:

Children with sickle cell disease (SCD) frequently and unpredictably present to the emergency department (ED) with pain. The painful event is the hallmark acute clinical manifestation of SCD, characterised by sudden onset and is usually bony in origin. This study aims to establish if 1.5mcg/kg of intranasal fentanyl (INF; administered via a Mucosal Atomiser Device, MAD™) is non-inferior to intravenous morphine 0.1 mg/kg in severe SCD-associated pain.

This study is a randomised,double-blind, double-dummy active control trial of children (weighing more than 10 kg) between 1 year and 21 years of age with severe painful sickle cell crisis. Severe pain is defined as rated seven or greater on a 0 to 10 age-appropriate numeric pain scale or equivalent. The trial will be conducted in a single tertiary urban paediatric ED in Dublin, Ireland. Each patient will receive a single active agent and a single placebo via the intravenous and intranasal routes. All clinical and research staff, patients and parents will be blinded to the treatment allocation. The primary endpoint is severity of pain scored at 10 min from administration of the study medications. Secondary endpoints include pain severity measured at 0, 5, 15, 20, 30, 60 and 120 min after the administration of analgesia, proportion of patients requiring rescue analgesia and incidence of adverse events. The trial ends at 120 min after the administration of the study drugs. A clinically meaningful difference in validated pain scores has been defined as 13 mm. Setting the permitted threshold to 50% of this limit (6 mm) and assuming both treatments are on average equal, a sample size of 30 patients (15 per group) will provide at least 80% power to demonstrate that INF is non-inferior to IV morphine with a level of significance of 0.05.

This clinical trial will inform of the role of INF 1.5mcg/kg via MAD in the acute treatment of severe painful sickle cell crisis in children in the ED setting.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Pain score as measured using the Faces, Legs, Activity, Cry, Consolability (FLACC) scale and Manchester Pain Ruler.	Severity of pain as measured using a validated pain score (visual analogue scale) at 10 minutes after administration of the intervention. The the Faces, Legs, Activity, Cry, Consolability (FLACC) scale and Manchester Pain Ruler will be used as age-appropriate pain scales for pre-verbal/early verbal children and older verbal children respectively.	10 minutes
Secondary	Pain score as measured using the Faces, Legs, Activity, Cry, Consolability (FLACC) scale and Manchester Pain Ruler.	Severity of pain as measured using a validated pain score (visual analogue scale) at 0, 5, 15, 20, 30, 60 and 120 minutes after administration of the intervention. The the Faces, Legs, Activity, Cry, Consolability (FLACC) scale and Manchester Pain Ruler will be used as age-appropriate pain scales for pre-verbal/early verbal children and older verbal children respectively.	0, 5, 15, 20, 30, 60 and 120 minutes
Secondary	The proportion of participants requiring rescue opioid requirement.	The proportion of patients requiring rescue opioid analgesia.	120 minutes
