Overview

Brief Summary

The purpose of this study is to determine the pharmacokinetics and safety of a nasal spray containing the anesthetic drug Tetracaine in combination with Oxymetazoline in healthy pediatric subjects.

Detailed Description

The purpose of this study is to determine the pharmacokinetics and safety of tetracaine, para- butylaminobenzoic acid (PBBA), and oxymetazoline after intranasal administration of the recommended, weight-based Phase 3 dose of Kovacaine Mist (Tetracaine Hydrochloride with Oxymetazoline Hydrochloride) to healthy pediatric subjects. Kovacaine Mist is an anesthetic solution containing 3% tetracaine hydrochloride and 0.05% oxymetazoline hydrochloride. A single spray dose of 100 μL Kovacaine Mist contains 3 mg tetracaine HCl and 0.05 mg oxymetazoline HCl. A two-100 μL spray dose (a total of 200 μL) of Kovacaine Mist contains 6 mg tetracaine HCl and 0.1 mg oxymetazoline HCl. A two-200 μL spray dose (a total of 400 μL) of Kovacaine Mist contains 12 mg tetracaine HCl and 0.2 mg oxymetazoline HCl. Kovacaine Mist will be administered based on the weight of the subject as summarized in the table below. Subjects weighing 10 to \<20 kg will receive 1 intranasal spray of 100 μL of Kovacaine Mist at time D0. Subjects weighing 20 to \<40 kg will receive 2 intranasal sprays of 100 μL (total dose 200 μL) administered 4 minutes apart at times D0 and D4. Subjects weighing 40 kg or more will receive 2 intranasal sprays of 200 μL (total dose 400 μL) administered 4 minutes apart at times D0 and D4.

•Sufficiently healthy as determined by the investigator to receive the test medications.
•Accompanied and/or represented by a parent or guardian able to comprehend and sign the informed consent document.
•Subject able to understand and provide assent to an age-appropriate subject assent form (as defined by local practice or regulation).
•Patient or parent/guardian able to communicate with the investigator and comply with the requirements of the protocol.
•Within the 10th and 90th percentiles for weight by age.
•Can breathe through both nostrils.
•Body mass index from 14 and 30 kg/m2 inclusive.

Exclusion Criteria

•Any chronic or currently uncontrolled psychiatric, neurological, endocrine, pulmonary, cardiovascular, renal, gastrointestinal or hepatic disease or condition with manifestations that might confound interpretation of study results or make receipt of study medication a source of risk for adverse outcome.
•Inadequately controlled thyroid disease of any type.
•Has clinically significant abnormal findings on the physical examination, medical history, or clinical laboratory evaluation during screening.
•Currently experiencing seasonal or perennial allergic rhinitis, recurrent nose-bleeds or asthma, or has a significant history of these conditions, in the opinion of the Investigator.
•Current, including the last 30 days, sinusitis or other upper respiratory infections, nasal congestion or use of a "sinus medication" within the 48 hours prior to anticipated study participation.
•Nasal polyps, significant nasal or sinus surgery or other abnormality that may interfere with the dose administration.
•History of allergy to or intolerance of tetracaine, oxymetazoline, benzyl alcohol, other ester local anesthetics, or para-aminobenzoic acid (as found in PABA-containing sunscreen).
•Use of a monoamine oxidase inhibitor within the 3 weeks preceding study entry.
•Nursing, pregnant, suspected of being pregnant, or trying to become pregnant. (Females of child-bearing potential will be required to undergo urine testing at the baseline visit to rule out pregnancy.)
•Having received any investigational drug (including Kovacaine Mist) and/or participation in any clinical trial within 30 days of study participation.
