Primary Outcome Measures:
  • Cohort 1: The proportion of subjects receiving Kovacaine Mist who do not require rescue anesthesia during the operative dental procedure performed on a tooth in the range of 4 to 13. [ Time Frame: at 15 minutes, with +10 minute window ] [ Designated as safety issue: No ]
  • Cohort 1: The proportion of subjects receiving Kovacaine Mist who do not require rescue anesthesia during the operative dental procedure performed on tooth 3 or 14. [ Time Frame: 15 minutes, with +10 minute window ] [ Designated as safety issue: No ]
  • Cohort 2&3: The proportion of subjects receiving Kovacaine Mist who do not require rescue anesthesia during the operative dental procedure performed on a tooth in the range of 4 to 13. [ Time Frame: at 10 minutes, with +5 minute window ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • The incidence of subjects receiving Kovacaine Mist with changes in systolic and diastolic blood pressure exceeding +/- 25% of preoperative measurements values. [ Time Frame: 60 minutes ] [ Designated as safety issue: Yes ]
  • The incidence of subjects receiving Kovacaine Mist with adverse changes in the naris airway. [ Time Frame: 60 minutes ] [ Designated as safety issue: Yes ]
  • The incidence of minor expected drug reactions after administration of Kovacaine Mist. [ Time Frame: 60 minutes ] [ Designated as safety issue: Yes ]
  • The proportion of subjects giving a positive response to evaluation question for subjective numbness assessment (SNA) after the procedure is completed. [ Time Frame: 60 minutes ] [ Designated as safety issue: No ]

Arms Assigned Interventions
Experimental: Kovacaine Mist, 4 sprays unilateral Drug: Tetracaine HCl 3% and oxymetazoline HCl 0.05%
Nasal spray with 0.1 mL per spray. Dose = 4 sprays of study drug per subject delivered at 4-minute intervals.
Experimental: Kovacaine Mist, 2 sprays unilateral Drug: Tetracaine HCl 3% and oxymetazoline HCl 0.05%
Nasal spray with 0.2 mL per spray. Dose = 2 sprays of study drug per subject delivered at 4-minute intervals.
Experimental: Kovacaine Mist, 1 spray unilateral Drug: Tetracaine HCl 3% and oxymetazoline HCl 0.05%
Nasal spray with 0.2 mL per spray. Dose = 1 spray of study drug per subject.

Detailed Description:

This is a Phase II single-center, open-label clinical trial with three dosing regimens, designed to determine the efficacy and optimal dose of the Kovacaine Mist intranasal delivery system for inducing pulpal anesthesia of maxillary teeth numbers 4-13 (maxillary right second premolar to maxillary left second premolar). Kovacaine will be administered intranasally on the same side of the midline as the tooth on which the procedure will be performed in three dosing cohorts [four 100 μL, two 200 μL, or one 200 μL spray(s)] of 10 subjects each. The first cohort receiving 4 sprays will be completed before initiating study of the remaining two cohorts, which will be treated using a randomized, parallel-group design. Administration: Subjects in the 4- and 2-spray cohorts will be administered the same total dose of 12 mg tetracaine HCl/0.2 mg oxymetazoline HCl. The 4-spray cohort will be treated with a sequence of four 100-μL sprays at intervals of 4 minutes. The 2-spray cohort will be treated with a sequence of two 200 μL sprays 4 minutes apart. The 1-spray cohort will be administered one 200 μL spray, a total dose of 6 mg tetracaine HCl/0.1 mg oxymetazoline HCl, which is half the dose of the 2-spray cohort. Rescue: If the study drug does not provide sufficient anesthesia to allow for completion of the dental procedure, a rescue injection of articaine will be administered.
