NovaDel Announces Positive Results from Pilot Study of Zolpidem Oral Spray vs. Ambien(R) Tablets.

-Company Plans to Launch Pivotal Trial in First Quarter 2007-

FLEMINGTON, N.J. -- NovaDel Pharma Inc. (AMEX AMEX

See: American Stock Exchange
: NVD See National Vulnerability Database. ) today announced positive results from a pilot pharmacokinetic study comparing its new and improved formulation of Zolpidem zolpidem /zol·pi·dem/ (zol-pi´dem) a non-benzodiazepine sedative-hypnotic; used as the tartrate salt in the short term treatment of insomnia.  Oral Spray to Ambien([R]) tablets. Zolpidem is the active ingredient An active ingredient, also active pharmaceutical ingredient (or API), is the substance in a drug that is pharmaceutically active. Some medications may contain more than one active ingredient.  in Ambien([R]), Sanofi-Aventis' leading treatment for insomnia.

In the study, subjects received Zolpidem Oral Spray or Ambien([R]) tablets in 5mg or 10mg doses. For fasting subjects, fifteen minutes after dosing, 80% of subjects using Zolpidem Oral Spray achieved blood concentrations of greater than 20 ng/ml, compared to 33% of subjects in the 5mg Ambien([R]) tablet group and 40% of subjects in the 10mg Ambien([R]) tablet group. The difference between the oral spray groups and tablet groups was statistically significant (p=0.016). Twenty ng/ml is a level generally believed to approximate the lower limit of the therapeutic range for zolpidem. Additionally, drug concentrations were measured at five and ten minutes post-dosing. At these early time points, the oral spray groups achieved drug levels five-to-thirty times greater than subjects in the corresponding tablet groups. These differences were also statistically significant.

"The performance of Zolpidem Oral Spray in this study indicates that this formulation has the potential for faster induction of sleep when compared to Ambien([R]) tablets," said Dr. Thomas Roth, Chief of Sleep Medicine at Henry Ford Hospital Henry Ford Hospital is a hospital located in Detroit, Michigan a few blocks from Wayne State University and the New Center area, near the Fisher Building and Cadillac Place. The hospital was founded in 1915 by Henry Ford as a philanthropic project.  in Detroit, Michigan “Detroit” redirects here. For other uses, see Detroit (disambiguation).

 condition, and there is a real need for improved products to bring faster onset of sleep to these patients."

"We expect that faster achievement of therapeutic drug concentration levels will translate into more rapid onset of sleep, which is a key objective for any sleeping medication being developed," stated Jan Egberts, M.D., President and CEO (1) (Chief Executive Officer) The highest individual in command of an organization.

"This study once again demonstrates the potential of NovaDel's oral spray technology to provide considerable benefits to patients in the form of faster-acting and more convenient dosing options. Based on these results, we plan to advance Zolpidem Oral Spray into pivotal trials in the first quarter of 2007 and submit a 505(b)(2) New Drug Application with the U.S. Food & Drug Administration by the end of the second quarter of next year."

Study Design and Results

Zolpidem Oral Spray was evaluated in a pharmacokinetic/pharmacodynamic study. This was a crossover study comparing 10mg oral spray, 10mg tablet, 5mg oral spray, and 5mg tablet doses under fasting conditions. The 10mg oral spray group was also evaluated under fed conditions. Ten healthy male volunteers completed the study. The study's endpoints included maximum concentration of drug (Cmax); time to the maximum concentration (Tmax); Area-under-the-Curve (AUC AUC

); and other pharmacokinetic parameters.

The pharmacokinetic evaluations also included parameters of early drug absorption. Under fasting conditions, the oral spray groups demonstrated consistently faster drug absorption than the tablet groups, while Cmax and relative bioavailability bioavailability /bio·avail·a·bil·i·ty/ (bi?o-ah-val?ah-bil´i-te) the degree to which a drug or other substance becomes available to the target tissue after administration.

. For fasting subjects, results showed that as early as 13 minutes post-dosing, the 5mg and 10mg oral spray groups achieved statistically significant treatment differences in reduction in DSST scores when compared to the 10mg tablet group (p=0.009 and p=0.003, respectively). At 8 hours post-dosing, DSST scores for oral spray and tablet groups were comparable, suggesting similar next-day residual effect in the oral spray group and the tablet group.

About Insomnia

According to the National Institutes of Health, more than 70 million Americans experience insomnia. An estimated $14 billion is spent each year on the direct costs of insomnia, which include treatment, healthcare services and hospital and nursing home care. Indirect costs, including lost work days, property damage from accidents, and transportation to and from healthcare providers, is estimated at $28 billion annually. Insomnia sufferers experience inadequate or poor quality sleep and report one or more of the following: difficulty initiating sleep, difficulty maintaining sleep, and waking up too early. The insomnia market is approximately $3 billion, with Ambien([R]) leading the market. Analysts predict that the insomnia market will reach $4 billion by the year 2010.

Ambien([R]) is a registeredtrademark of Sanofi-Aventis.
