About

This Phase 3 clinical study is designed as a multicenter, randomized, blinded, controlled study to evaluate the efficacy, pharmacodynamics, and safety of NV-101 administered as a submucosal injection following completion of a restorative or periodontal maintenance procedure requiring local anesthesia with an agent containing a vasoconstrictor. Local vasodilatation that results in more rapid clearance of the anesthetic is the proposed mechanism of action.

Inclusion criteria

Male or female greater than or equal to 12 years
Sufficiently healthy, as determined by the Investigator, to receive routine dental care

- supraperiosteal injection.
Dental procedure is completed within 60 minutes of the first administration of local anesthetic
Normal upper lip sensations at baseline prior to administration of local anesthetic
Upper lip on the side of the procedure is numb (no feeling) at the completion of the dental procedure
Soft tissue anesthesia recovery score of zero prior to anesthetic
Functional Assessment Battery by subject and observer rating is normal prior to anesthetic

Concurrent conditions: any incapacitating medical condition (e.g. unstable angina, uncontrolled cardiac arrhythmias, uncontrolled hypertension, uncontrolled hyperthyroidism); significant infection or inflammatory process of the oral cavity.
Concomitant medications: use of an opioid or opioid-like analgesic (e.g. codeine, tramadol, pentazocine) within 24 hours prior to administration of anesthetic
