Trial Outcomes & Findings for Phase 2 Study IV QUZYTTIR™ (Cetirizine Hydrochloride Injection) vs V Diphenhydramine (NCT NCT04189588)

NCT ID: NCT04189588

Last Updated: 2023-10-06

Results Overview

Compare the number of patients experiencing any infusion reaction events, and the number and percentage of patients experiencing each symptom of infusion reactions (flushing, itching, alterations in heart rate and blood pressure, dyspnea, chest discomfort, acute back or abdominal pain, fever, shaking chills, nausea, vomiting, diarrhea, skin rashes, throat tightening, hypoxia, seizures, dizziness, or syncope) to treatment with anti-CD20 such as Rituxan® (rituximab) or Paclitaxel after premedication with intravenous (IV) QUZYTTIR™ cetirizine hydrochloride (HCl) or IV diphenhydramine during first-cycle infusion or re-treatment after 6 months or in patients with persistent infusion reactions while on maintenance with anti-CD20 such as Rituxan® (rituximab) or Paclitaxel. The infusion reactions will be evaluated following the Common Terminology Criteria for Adverse Events (CTCAE version 5.0) definitions of graded infusion reactions.

Cohort A
Cetirizine HCl 10 mg/mL: a single 1 mL injection. Diphenhydramine 50 mg/mL: Comparison of two injectable products: cetirizine HCl 10 mg/mL and diphenhydramine 50 mg/mL, both administered during a 1 to 2-minute period by IV push using a 1 mL syringe anti-CD20 such as Rituximab or Paclitaxel: Compare the incidence of infusion reactions to treatment with an anti-CD20 such as Rituxan® (Rituximab) or Taxol® (Paclitaxel) after premedication with intravenous (IV) QUZYTTIR™ cetirizine hydrochloride (HCl) or IV diphenhydramine during first-cycle infusion or re-treatment. Re-treatment is defined as re-treatment with Rituxan® (Rituximab) or Paclitaxel after 6 months in patients with persistent infusion reactions while on maintenance or re-treatment.

Timeframe: 1 hour, 2 Hours and at discharge

Population: Per Patient Analysis set (patients with a baseline sedation score = 0)

Patient sedation scores at 1 hour and 2 hours post-injection of antihistamine (IV cetirizine HCl or IV diphenhydramine) and at discharge. The patient sedation scores are assessed on a scale of 0-4, with 0=None and 4=Extremely Severe (Asleep, Cannot Self-Rate). The HCP sedation scores are assessed on a scale of 0-4, with 0=None and 4=Extremely severe.
