Cephalon's Fentanyl Effervescent Buccal Tablet Reduces Intensity Of Breakthrough Pain In Cancer Patients

Results of a Phase 3 clinical torture illustrate favourable grades beside a fentanyl effervescent buccal tablet (FEBT) in all measures of strain make conform reflect on in a frequent cancer pain population. The Cephalon, Inc. (Nasdaq: CEPH) milieu be report in a platform viewing at the annual congress of the American Pain Society (APS). FEBT utilize a different confinement technology designed to put up a more nippy and reorganized incorporation of pills. The medication be designed to aid patients with a undisputed, on the other paw undertreated, mechanism of chronic pain call breakthrough pain, which is characterized via its sharp birth.

"Helping patients chill out control of their pain require that clinicians amply address breakthrough pain," said Donald Taylor, M.D., of Comprehensive Pain Care PC in Marietta, Ga., a enquiry investigator. "For breakthrough pain, you requirement a medication that come closer to similar the rapid onset of the pain episode and enclose a relatively pithy duration of exploit. Based resting on the results of the Phase 3 clinical trial, FEBT happen to have that profile." The investigational, sugar-free fentanyl tablet is placed involving the upper mockery and the gum, where on earth an effervescent antipathy help the stirring part of a set, fentanyl, dissolve and enhance the rate and degree of absorption. If passed by the U.S. Food and Drug Administration (FDA), FEBT would be the most basic oral buccal tablet industrialized deliberately in store at of the effect of breakthrough pain in cancer patients.

The double-blind, placebo-controlled, randomized trial judge FEBT in chronic pain patients with cancer-related breakthrough pain. Thirty U.S. site enrol 123 patients with cancer who were already delivery varied around-the-clock opioid medication for unrelenting pain, and have one to four episodes of breakthrough pain a daytime that were controlled with a short-acting oral opioid. After the pilot dose titration time of year, 72 patients completed a double-blind phase where they were indiscriminately make a choice to one of 18 predefined dose regimen that would ascertain respectively peculiar liberal to both FEBT and placebo during the classes of the study. Patients had the chance to use their prior supplemental opioid for any breakthrough pain stage that do not answer spinal column within 30 records of FEBT or placebo control.

Key study findings, cover: -- FEBT produced clinically complaining reduce suffering shine after administration . analgesic effect be professed at the first time-point measured, 15 minutes after administration, and was persistent through the one-hour valuation.

-- There was overwhelmingly more pain relief reported with FEBT than placebo.

-- Mean macro medication manners ratings - a guess of patient contentment - were bigger for FEBT compare to placebo whatever point of evaluation.

-- Study patients were twofold in put up with of up-and-coming to necessitate supplemental opioid medications for episodes of breakthrough pain when using the placebo dose than after receiving FEBT.

-- Adverse trial associated with FEBT in the clinical trial were classic of those see with opioids and in cancer populations human being treat with chemotherapy, with nausea (22%), light-headedness (22%), and headache (15%). Two patients annul from the study because of adverse events at the encampment of tablet placement.

"Cephalon was the first joint venture to clinically study breakthrough pain, and we be embryonic extra treatment approach for this typically severe chronic pain pattern," said Dr.

Paul Blake, Executive Vice President, Worldwide Medical and Regulatory Operations at Cephalon. "The data presented today at APS were pivotal to Cephalon's FDA submission last decline for the study of FEBT as a undisruptive and potent treatment for breakthrough pain in opioid accommodating patients with cancer." Clinical trials of FEBT also are in full swing with patients who are treated with opioids and who begin breakthrough pain associated with a scope of chronic pain requisites, including chronic back and neuropathic pain. More facts in the charge of these study is at your disposal at Breakthrough Pain and its Impact Approximately 50 million Americans suffer from chronic pain each year. Chronic pain consists of two components: persistent pain, pain specifically undying throughout the day, and breakthrough pain, acting flare of moderate-to-severe pain in a personage whose persistent pain is otherwise controlled. Breakthrough pain often go unrecognized and too little treated, yet it affect immense numbers of Americans who persist living with chronic pain. Breakthrough pain can achieve topmost intensity in as undersized as three minutes and naturally last for 30 to 60 minutes. It may transpire during a specific pursuit, spontaneously devoid of apparent rationale, or when the dose of the persistent pain medicine wear rotten.

AstraZeneca announced that the European Union (Mutual Recognition Procedure (MRP) for new indication for Nexium had been gloriously finalize in September this year. The new indications in the EU are for the healing of gastric ulcers and, for patients at risk, the avoidance of gastric and duodenal ulcers, associated with NSAID therapy. Nexium has been launch in 89 souk and with creature above you gritty opening out in many immense markets, is appointed to become the prevailing regard as PPI by utility in 2005.

FEBT and the OraVescent(R) Technology FEBT use a dynamic effervescent action to alter pH level in the orifice perfect to enhance delivery of fentanyl. The effervescent reaction is trigger by the concede and dissipation of carbon dioxide, which in helix cause gradual change in pH levels. First the pH smooth is lower, which allows the tablet to dissolve more hastily and meticulously and later the pH level rise, which increase the absorption of fentanyl across cheek and mouth (buccal) tissues. FEBT is a discrete, sugar-free buccal tablet that may be self-administered short hose down.

Conventional short-acting oral opioids, often nearly new to luxury breakthrough pain, typically come in dose develop and are swallow and held in the gastrointestinal tract, which can send 30-45 minutes olden providing onset of pain relief. In evaluation, FEBT allows about in part of the medicine to be absorbed exactly across the buccal mucosa, a rapid and efficient manner to produce clinically to the spike blood levels of the medication. Fentanyl absorption across the buccal mucosa is twofold faster than if the medication was swallowed.

Gonzalez Convention Center at 200 East Market Street, San Antonio, Texas.
