POINT RICHMOND, Calif., Nov. 26, 2012 /PRNewswire/ -- Transcept Pharmaceuticals, Inc. (Nasdaq: TSPT) announced today that Purdue Pharmaceutical Products, L.P. (Purdue), the Transcept U.S. commercialization partner for Intermezzo® (zolpidem tartrate) sublingual tablet C-IV, is launching a national direct-to-consumer (DTC) promotional campaign, including digital, print and television advertising to support Intermezzo commercialization. Intermezzo digital and print DTC campaigns began in November 2012 and television promotion is expected to begin in February 2013. Elements of the online DTC campaign will be available at www.myintermezzo.com later in December 2012.
Purdue has committed $19 million to this consumer advertising campaign, and Transcept plans to provide an additional $10 million. This $29 million program will be primarily executed during the first six months of 2013.
To reinforce the DTC promotional campaign, Purdue plans to utilize for the first time its established analgesic sales force, which consists of approximately 525 sales representatives, to promote Intermezzo to primary care prescribers and certain medical specialists. Purdue will continue to market Intermezzo to psychiatrists and other specialty prescribers with a specialty sales force of approximately 90 sales representatives who are exclusively devoted to Intermezzo.
Intermezzo is the first and only prescription sleep aid approved for use as needed for the treatment of insomnia when a middle-of-the-night awakening is followed by difficulty returning to sleep. Intermezzo is not indicated for the treatment of middle-of-the-night insomnia when the patient has fewer than four hours of bedtime remaining before the planned time of waking. Intermezzo was developed by Transcept and is the Company's first FDA approved product. Intermezzo is being marketed in the United States under the terms of a collaboration agreement between Transcept and Purdue.
"We are very excited to be working with our partner Purdue to launch the next phase of the Intermezzo commercialization plan," stated Glenn A. Oclassen, President and CEO of Transcept. "We expect that the DTC campaign will help educate consumers about Intermezzo's unique indication within the insomnia therapeutic category."
"The new Intermezzo consumer advertising campaign supports our commitment to enhanced prescriber and patient education," commented John H. Stewart, President and CEO of Purdue. "We believe that Intermezzo addresses a significant medical need, and we remain committed to increasing awareness of Intermezzo and making the product available to those insomnia patients for whom it is appropriate."
Important Safety Information
Intermezzo is contraindicated in patients with known hypersensitivity to zolpidem. Observed reactions with zolpidem include anaphylaxis and angioedema.
Co-administration with Intermezzo and other CNS depressants increases the risk of CNS depression. Intermezzo should not be taken with alcohol. The use of Intermezzo with other sedative-hypnotics (including other zolpidem products) at bedtime or the middle of the night is not recommended.
The risk of next-day driving impairment (and psychomotor impairment) is increased if Intermezzo is taken with less than four hours of bedtime remaining; if a higher than recommended dose is taken; if co-administered with other CNS depressants; or co-administered with other drugs that increase the blood levels of zolpidem. A small negative effect on SDLP (standard deviation of lateral position, a measure of driving impairment) may remain in some patients four hours after the 1.75 mg dose in women, and after the 3.5 mg dose in men, such that a potential negative effect on driving cannot be completely excluded.
Additional Important Safety Information is presented below.
Intermezzo is the first and only prescription sleep aid approved for use as needed for the treatment of insomnia when a middle-of-the-night awakening is followed by difficulty returning to sleep. Intermezzo is not indicated for the treatment of middle-of-the-night insomnia when the patient has fewer than four hours of bedtime remaining before the planned time of waking. Intermezzo is contraindicated in patients with known hypersensitivity to zolpidem. Observed reactions with zolpidem include anaphylaxis and angioedema.
The safety and efficacy of Intermezzo was evaluated in two randomized, double-blind, placebo-controlled studies in patients with insomnia characterized by difficulty returning to sleep after a middle-of-the-night awakening. Patients met the diagnosis for primary insomnia as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV-TR) and had at least 3 prolonged middle-of-the-night awakenings per week of at least 30 minutes in duration.
In a four-week outpatient study in 295 adult patients aged 18 to 64 years (201 females, 94 males), Intermezzo 3.5 mg or placebo was taken on an as-needed basis following spontaneous awakenings when patients had difficulty returning to sleep after waking in the middle of the night, provided they had at least four hours remaining in bed. Subjective time to fall back to sleep after a middle-of-the-night awakening was significantly shorter for Intermezzo 3.5 mg (38 minutes) compared to placebo (56 minutes). The most commonly observed adverse reactions ( > 1% ) were headache (Intermezzo 3%, placebo 1%), nausea (1% for both patient groups), and fatigue (Intermezzo 1%, placebo 0%).
In a sleep laboratory study, 82 adult patients aged 19 to 64 years (58 females, 24 males) were evaluated in a 3-period, 2-consecutive-night treatment period cross-over design. Patients were awakened four hours after bedtime, administered Intermezzo 3.5 mg, 1.75 mg, or placebo, and were kept awake for 30 minutes before lights-out. As compared to placebo, Intermezzo significantly decreased objective mean time to fall back asleep after a middle-of-the-night awakening (women taking 1.75 mg: 16 min vs. placebo: 28 min; men taking 3.5 mg: 13 min vs. placebo: 29 min).
How to Take Intermezzo
The recommended and maximum dose of Intermezzo for male adults is 3.5 mg and for female adults is 1.75 mg, administered as a sublingual tablet only once per night as needed if a middle-of-the-night awakening is followed by difficulty returning to sleep. The recommended doses for men and women are different because women clear zolpidem from the body at a lower rate than men.
The recommended dose for elderly men and women over 65 years old or patients with hepatic impairment is 1.75 mg. The recommended dose for men and women who are taking concomitant CNS depressants is 1.75 mg. Dose adjustment of concomitant CNS depressants may be necessary when co-administered with Intermezzo because of potentially additive effects. The use of Intermezzo with other sedative-hypnotics (including other zolpidem products) at bedtime or the middle of the night is not recommended.
Intermezzo is to be taken in bed when a patient wakes in the middle of the night and has difficulty returning to sleep. Intermezzo should only be taken if the patient has at least four hours of bedtime remaining before the planned time of waking.
Intermezzo should be placed under the tongue and allowed to disintegrate completely before swallowing. The tablet should not be swallowed whole. For optimal effect, Intermezzo should not be administered with or immediately after a meal. The blister should be removed from the pouch just prior to dosing.
Each sublingual tablet is individually packaged in a foil blister inside a unit-dose pouch. Before going to bed, a single pouch should be placed by the bedside with a clock or watch nearby. All other unopened Intermezzo pouches should be stored with other medicines away from the bedside. Patients should open the Intermezzo pouch only when they are ready to use it.
Patients can either use the Dosing Time Chart or the Dosing Time Tool that comes with Intermezzo to find the latest time during the night they can take Intermezzo.
Dosing Time Tool: Patients turn a wheel to find the earliest time they must be awake, which corresponds with instructions to take Intermezzo before a specified time.
Dosing Time Chart: The chart helps patients locate the earliest time they need to be awake and match it to the latest time they can take Intermezzo.
When patients wake in the morning, they should make sure that at least four hours have passed since they took Intermezzo and they feel fully awake before driving or engaging in other activities requiring full mental alertness. Patients should not do dangerous activities until they know how Intermezzo affects them.
Additional Important Safety Information
The failure of insomnia to remit after 7 to 10 days of treatment may indicate the presence of a primary psychiatric and/or medical illness that should be evaluated.
Cases of angioedema involving the tongue, glottis, or larynx have been reported in patients after taking the first or subsequent doses of zolpidem. Some patients have had additional symptoms such as dyspnea, throat closing, or nausea and vomiting that suggest anaphylaxis. Some patients have required medical therapy in the emergency department. Angioedema and additional symptoms suggesting anaphylaxis may be fatal. Patients who develop angioedema or anaphylaxis should not be re-challenged.
Abnormal thinking and behavior changes have been reported in patients treated with a sedative-hypnotic, including zolpidem. Complex behaviors, including driving or eating while not fully awake, with amnesia for the event, as well as visual and auditory hallucinations and abnormal behaviors such as decreased inhibition, bizarre behavior, agitation, and depersonalization may occur. Although behaviors such as "sleep-driving" have occurred with zolpidem alone at therapeutic doses, the co-administration of zolpidem with alcohol and other CNS depressants increases the risk of such behaviors, as does the use of zolpidem at doses exceeding the maximum recommended dose. Discontinuation of Intermezzo should be strongly considered for patients reporting a "sleep-driving" episode.
In primarily depressed patients, worsening of depression, including suicidal thoughts and actions (including completed suicides) have been reported with the use of sedative-hypnotics. Intentional overdosage is more common in this group of patients; therefore, protective measures may be required. Prescribe the least amount of Intermezzo that is feasible in these patients.
Because persons with a history of addiction to or abuse of drugs or alcohol are at increased risk for misuse, abuse, and addiction of zolpidem, they should be monitored carefully when receiving Intermezzo. Zolpidem tartrate is a Schedule IV controlled substance. Post-marketing reports of abuse, dependence, and withdrawal resulting from use of oral zolpidem tartrate have been received. Zolpidem has produced withdrawal signs and symptoms following a rapid dose decrease or abrupt discontinuation.
