Study of NV-101 for Efficacy, Pharmacodynamics, and Safety in Dental Patients Undergoing Mandibular Procedures
The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government.
Read our disclaimer for details.
This Phase 3 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 vasodilation that results in more rapid clearance of the anesthetic is the proposed mechanism of action.

Ages Eligible for Study:
12 Years and older (Child, Adult, Senior)
Sexes Eligible for Study:
Accepts Healthy Volunteers:
Male or female greater than or equal to 12 years
Sufficiently healthy, as determined by the Investigator, to receive routine dental care
Requires a restorative procedure in the mandible such as cavity preparation, restoration/filling, or crown or a periodontal maintenance procedure, such as teeth cleaning (non-surgical scaling and/or root planing) on the same side of the lower mouth
Requires one or two cartridges of local anesthesia administered by one of the following intraoral injection techniques:
inferior alveolar nerve block;
Gow-Gates nerve block;
mental-incisive block; or
Dental procedure is completed within 60 minutes of the first administration of local anesthetic
Normal lower lip and tongue sensations at baseline prior to administration of local anesthetic
Lower 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
Negative urine pregnancy test at screening in all females of childbearing potential past menarche (includes all females except for those whose menstrual periods have not occured for greater than or equal to 1 year after menopause, who are surgically sterilized or who had a hysterectomy)
Understands and gives written informed consent
Subjects 12 to 17 years of age give written assent and parent(s) or legal guardian(s) give written informed consent
Can communicate with the Investigator and study staff, and can understand and comply with the requirements of the protocol
History or presence of any condition that contraindicates routine dental care
Requires more than two cartridges of local anesthetic (excluding supplemental injections) or use of nitrous oxide or sedatives to perform the scheduled dental procedure
Scheduled dental procedure takes greater than 60 minutes to complete
Unable to tolerate 1 liter of water over 5 hours
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
Allergy or intolerance to lidocaine, articaine, prilocaine, mepivacaine, epinephrine, levonordefrin, sulfites, phentolamine, or topical benzocaine
Has used an investigational drug and/or participated in any clinical study within 30 days of study drug administration
Has participated in this study or any previous study of phentolamine mesylate for reversal of local soft tissue anesthesia (STA)
Any condition which, in the opinion of the Investigator, increases the risk to the subject of participating in this study or decreases the likelihood of compliance with the protocol
