Comparison of Intranasal Kovacaine Mist, Tetracaine Alone, and Placebo for Anesthetizing Maxillary Teeth

Detaljert beskrivelse
The study will employ a multi-center, randomized, double-blind, placebo-controlled, parallel-groups design to assess the safety and efficacy of Kovacaine Mist delivered intranasally for inducing pulpal anesthesia of maxillary teeth numbers 4 to 13 (maxillary right second premolar to maxillary left second premolar) sufficient to allow completion of the Study Dental Procedure.
A total of 140 subjects, randomized 2:2:1 (Kovacaine Mist:Tetracaine alone:Placebo) will be enrolled to achieve 125 completed subjects; a total of 50 Kovacaine Mist subjects, 50 tetracaine alone subjects and 25 placebo subjects. Recruitment will be from diverse dental patient populations. At the two study sites, a balanced enrollment of 70 subjects each is planned to allow for a potential 10% drop-out rate.

Beskrivelse
Inclusion Criteria:
- Male or female 18 years of age or older.
- Need for an operative restorative dental procedure requiring local anesthesia for a single vital maxillary tooth (other than a maxillary first, second, or third molar) with no evidence of pulpal pathology.
- Normal lip, nose, eyelid, and cheek sensation.
- Able to understand and sign the study informed consent document, communicate with the investigators, and understand and comply with the requirements of the protocol.
- Patency of the naris ipsilateral to the tooth undergoing the Study Dental Procedure.
- Resting heart rate (HR) between 55 and 100 beats per minute (bpm), inclusive.
- Seated systolic blood pressure (SBP) between 95 and 140 mm Hg, inclusive and seated diastolic blood pressure (DBP) between 60 and 90 mm Hg, inclusive.
Exclusion Criteria:
- Inadequately controlled hypertension (blood pressure greater than 140/90 mm Hg).
- Inadequately controlled active thyroid disease of any type.
- Frequent nose bleeds (≥ 5 per month).
- Having received dental care requiring a local anesthetic within the last 24 hours.
- History of allergy to or intolerance of tetracaine, benzyl alcohol, other ester local anesthetics, or para-aminobenzoic acid (as found in PABA-containing sunscreen).
- History of allergy or hypersensitivity to articaine, oxymetazoline, epinephrine, or sulfite preservatives.
- 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 take a urine pregnancy test on the day of, but prior to, study drug administration to rule out pregnancy.)
- Having received any investigational drug and/or participation in any clinical trial within 30 days prior to study participation.
- Having used oxymetazoline or phenylephrine nasal spray, nasal irrigation, or other nasal or oral decongestant on the day of the study procedure.
- History of congenital or idiopathic methemoglobinemia
