Condition(s) targeted: Anesthesia, Dental

Intervention: Phentolamine Mesylate (NV-101) (Drug)

Phase: Phase 3

Status: Completed

Sponsored by: Novalar Pharmaceuticals, Inc.

Official(s) and/or principal investigator(s):
Athena Papas, DMD, Principal Investigator, Affiliation: Tufts University School of Dental Medicine

Summary

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.

Clinical Details

Official title: A Phase 3, Multicenter, Randomized, Blinded, Controlled Study of NV-101 for Efficacy, Pharmacodynamics and Safety in Dental Patients Undergoing Maxillary Procedures

Study design: Allocation: Randomized, Endpoint Classification: Safety/Efficacy Study, Intervention Model: Single Group Assignment, Masking: Single Blind, Primary Purpose: Treatment

Primary outcome: to determine if NV-101 accelerates time to normal sensation of the upper lip compared to control, as measured by standardized palpation procedure

Secondary outcome:

to determine if NV-101 accelerates the time to STAR-7 score of zero, as measured by soft tissue anesthesia questionnaire

to determine if NV-101 accelerates the time to normal function, as measured by a functional assessment battery

to determine if NV-101 accelerates the time to normal sensation of the tongue, as measured by standardized palpation procedure

to characterize the pharmacodynamic profile of NV-101, as measured by onset and offset of treatment effect

to evaluate the safety and tolerability of NV-101

Eligibility

Minimum age: 12 Years. Maximum age: N/A. Gender(s): Both.

Criteria:

Inclusion Criteria:

- 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 Exclusion Criteria:

- 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
