Comfortably "Un-Numb"... Novalar Receives FDA Approval for OraVerse

Interesting news for those who don't like that "frozen" feeling. From the company press release:

Novalar Receives FDA Approval for OraVerse

First approved dental anesthetic reversal agent

Novalar Pharmaceuticals, Inc., a dental specialty
pharmaceutical company, announced today that the United States Food and Drug
Administration (FDA) has granted marketing approval for OraVerse (phentolamine
mesylate). OraVerse is the first pharmaceutical agent indicated for the reversal of soft-
tissue anesthesia and the associated functional deficits resulting from a local dental
anesthetic. Novalar is establishing a specialty direct sales force to launch OraVerse in
late 2008.

“The approval of OraVerse is the result of the outstanding efforts of our development
team, our strong collaboration with the FDA and our focus and commitment to realizing
the vision of our founder, Dr. Eckard Weber. This first-in-class therapeutic will provide
dental professionals with a novel solution to enhance the overall experience for their
patients,” stated Donna Janson, President and Chief Executive Officer of Novalar.

Novalar plans to launch OraVerse at this year’s American Dental Association (ADA)
Annual Session being held in San Antonio, Texas from October 16-20, 2008. Novalar’s
sales force will focus on general and pediatric dentists for use in patients over six years
of age.

Over 300 million cartridges of local dental anesthetic are sold each year in the U.S.
alone. Although widely used, it frequently results in unnecessary and lingering soft
tissue anesthesia and associated functional deficits. Novalar’s market research with
both patients and dentists has indicated strong interest in a product that will reduce the
time to normal sensation and function following local dental anesthesia.

OraVerse’s approval for use in adults and children is based on data from several clinical
studies, including two Phase 3 studies in adults and adolescents age 12 and older and a
Phase 2 pediatric study. The two Phase 3 studies were conducted in 18 centers across
the United States, including leading dental schools, clinical research organizations and
private clinics. There were 484 dental patients enrolled across the two studies.

In the randomized, double-blinded, controlled Phase 3 studies, following the
administration of local anesthetics and completion of the dental procedure, patients were
administered either OraVerse or control. OraVerse reduced the median time to recovery
of normal sensation in the lower lip (as measured by standardized lip tapping
procedures) by 85 minutes compared to control. OraVerse reduced the median time to
recovery of normal sensation in the upper lip by 83 minutes. Within one hour after
administration of OraVerse, 41% of patients reported normal lower lip sensation as
compared to 7% in the control group, and 59% of patients in the OraVerse group
reported normal upper lip sensation as compared to 12% in the control group. In both
Phase 3 studies, the primary endpoint showed that OraVerse was statistically different
compared to control (p<0.0001).

The multi-center, randomized, double-blinded, controlled Phase 2 pediatric study
evaluated the safety and efficacy of OraVerse in the reversal of soft tissue anesthesia in
patients undergoing dental procedures after receiving local anesthetic. This study
enrolled 152 patients: 96 patients in the OraVerse group and 56 patients in the control
group. Of the 152 patients enrolled, 115 were trainable in the assessment method: 72
patients in the OraVerse group and 43 patients in the control group. The study
assessed OraVerse’s efficacy through the measurement of time to normal lip sensation
for those trainable in the assessment. The median time to normal sensation in patients
age 6-11 was reduced by 75 minutes for the OraVerse treated group, a 56%
acceleration of the time to normal sensation.

In all OraVerse clinical trials, there were no serious adverse events reported and the
most common adverse reaction that was greater than control was transient injection site
pain. Although tachycardia and cardiac arrhythmia may occur with the parenteral use of
alpha-adrenergic blocking agents, such events are uncommon after submucosal
administration of OraVerse.

“The Novalar team is extremely excited to bring to market a first-in-class product with
such strong interest from both patients and dentists,” added Ms. Janson. “It is seldom
that a company is able to conceive, develop and market such an innovative product that
has the ability to change the standard of care in dentistry. Novalar is committed to
making OraVerse a commercial success and believes we are well positioned to bring
additional dental pharmaceuticals to market through our unique development

About OraVerse
OraVerse (phentolamine mesylate) Injection is the only local anesthetic reversal agent
that accelerates the return to normal sensation and function following restorative and
periodontal maintenance procedures. OraVerse is indicated for the reversal of soft-tissue
anesthesia, i.e., anesthesia of the lip and tongue, and the associated functional deficits
resulting from an intraoral submucosal injection of a local anesthetic containing a
vasoconstrictor. OraVerse is not recommended for use in children less than six years of
age or weighing less than 15 kg (33 lbs).

  1. I've been injected with an anesthesia before. My Atlanta sedation dentist went for that instead of putting me to sleep because only one tooth had to be extracted. I found it uncomfortable because it felt like my lips expanded, and I wasn't able to speak normally for a few hours.

    But it's not really something I'm bothered with. It's also the same for some people here in Atlanta. Sedation dentistry recognizes local anesthesia as a great alternative. But I'm glad that they came up with that innovative product, since it's better if we feel the numbness for a shorter period of time.
