研究概览
简要总结
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.

入选标准
- •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 maxilla 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 upper 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;
- •Vazirani-Akinosi block;
- •mental-incisive block; or
- •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
- •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
排除标准
- •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
结局指标
主要结局
to determine if NV-101 accelerates time to normal sensation of the upper lip compared to control, as measured by standardized palpation procedure
次要结局
- to evaluate the safety and tolerability of NV-101
- to determine if NV-101 accelerates the time to normal sensation of the tongue, as measured by standardized palpation procedure
- to determine if NV-101 accelerates the time to STAR-7 score of zero, as measured by soft tissue anesthesia questionnaire
- to characterize the pharmacodynamic profile of NV-101, as measured by onset and offset of treatment effect
- to determine if NV-101 accelerates the time to normal function, as measured by a functional assessment battery
