Overview
Brief Summary
This is a multicenter, parallel group, randomized, double-blind, active controlled, Phase III clinical study of cetirizine injection, 10 mg/mL, compared to diphenhydramine injection, 50 mg/mL (Benadryl or generic equivalent) with acute urticaria requiring treatment.
Detailed Description
This was a multi-center, parallel group, randomized, double-blind, active controlled, Phase III clinical trial of cetirizine injection 10 mg/mL versus diphenhydramine injection 50 mg/mL (Benadryl or generic equivalent) in approximately 256 subjects who either presented to Emergency Departments, hospitals, allergy clinics or Urgent Care Centers with acute urticaria, or developed acute urticaria following allergen challenge at an Allergy Clinic. Patients signed an informed consent and were evaluated for eligibility for inclusion to treat. Eligible subjects were assessed for baseline characteristics, medical and surgical histories, concomitant medications and given a brief physical exam. Subjects were then randomized, in a 1:1 ratio, to blindly receive either cetirizine 10 mg/mL injection or diphenhydramine 50 mg/mL injection. Efficacy assessments included patient-rated severity of pruritus, physician assessments of extent of urticaria/erythema, and sedation score. Subjects remained in the treatment center for at least after the 1 hr assessment, after which they may have been discharged at the physician's discretion. Safety was monitored through the reporting of adverse events for up to 28 days following treatments and by monitoring vital signs at planned intervals from admission into the treating facility until readiness for discharge. After 24 and 48 hrs after discharge, subjects were contacted by phone for follow-up questions regarding recurrence of symptoms, new symptoms, additional medication taken, side effects from medication taken after discharge, relapse requiring a return to treatment center, and return to normal activities.
Investigators
Eligibility Criteria
Inclusion Criteria
- •Male or female patients with a diagnosis of acute urticaria who need treatment with antihistamine to alleviate their symptoms;
- •18 years of age or older;
- •Be willing and able to give informed consent;
- •Patients with a Patient rated Pruritus Severity Score ≥ 1
Exclusion Criteria
- •Receipt of an investigational drug or device, within the past 30 days;
- •Patients in whom an antihistamine may be contraindicated (e.g. narrow angle glaucoma, symptomatic prostatic hypertrophy);
- •Patients who, in the opinion of the investigator, may not tolerate an IV injection of diphenhydramine 50 mg, or cetirizine 10 mg;
- •Receipt of any antihistamine (H1 antagonist) within the past 2 hours regardless of the route of administration, e.g. diphenhydramine, cetirizine, loratadine, fexofenadine, levocetirizine, desloratadine;
- •Receipt of an H2 antagonist within the past 2 hours;
- •Receipt of doxepin within the past 2 hours; doxepin is an antidepressant, but it also has antihistamine properties;
- •Receipt of steroids by the oral, IV, IM, or inhalational routes route within the past 4 hours to manage an acute allergic reaction;
- •Receipt of epinephrine (EpiPen or any other brand) within the past 20 minutes;
- •Anaphylaxis prior to the acute anaphylactic symptoms having been treated.
- •Has known allergy to hydroxyzine, cetirizine or levocetirizine, or diphenhydramine;
Arms & Interventions
Test Drug
JDP-205 Injection, 10 mg/mL, 1 mL
Intervention: Test Drug (JDP-205)
Control
Diphenhydramine Injection, 50 mg/mL, 1 mL
Intervention: Active Control (Diphenhydramine)
Outcomes
Primary Outcomes
Change of Patient Rated Pruritus Score
Time Frame: 2 hr
Change from baseline to 2 hours in patient-rated pruritus Severity score (values at 2 hours minus Baseline) Patient Pruritus Severity Score Ask the patient "How severely are your hives itching at the moment?" 0 = none 1. = mild (minimal awareness, easily tolerated) 2. = moderate (definite awareness, quite bothersome) 3. = severe (difficult to tolerate)
Secondary Outcomes
- Time to Discharge(up to 24 hours)
- Patient Sedation Scores(2 hours)
- Number of Patients Who Needed to Return to Treatment Center(up to 24 hrs)
