Healthcare Industry News: Neuropathic Pain
News Release - September 25, 2006
Cephalon Receives FDA Approval of FENTORA(TM) (fentanyl buccal tablet) for the Management of Breakthrough Pain in Patients with CancerFRAZER, Pa., Sept. 25 (HSMN NewsFeed) -- Cephalon, Inc. (Nasdaq: CEPH ) announced today that it has received approval from the U.S. Food and Drug Administration (FDA) to market FENTORA(TM) (fentanyl buccal tablet) [C-II] for the management of breakthrough pain in patients with cancer who are already receiving and who are tolerant to opioid therapy for their underlying persistent cancer pain. FENTORA is the first and only buccal tablet approved for this indication and is the second new product to be marketed by Cephalon this year. Cephalon expects FENTORA to be available in the United States during the first week of October 2006.
"The approval of FENTORA not only allows us to extend our leadership position in the pain management arena, but also to provide a medication that is better designed to meet the needs of cancer patients with breakthrough pain," said Frank Baldino, Jr., Ph.D., Chairman and CEO. "Our longer-term clinical strategy is focused on developing FENTORA for patients with breakthrough pain associated with other conditions, including Neuropathic Pain and back pain."
Robert P. Roche, Jr., Executive Vice President, Worldwide Pharmaceutical Operations, added, "We are very excited to be providing clinicians and their patients with cancer with this innovative new treatment for breakthrough pain. With our recognized expertise in this area developed over many years, our dedicated pain sales force, and established relationships in the pain marketplace, we are well positioned for a successful launch of FENTORA."
Breakthrough pain is a common component of chronic pain characterized by its rapid onset, intensity, and relatively short duration. An estimated 800,000 cancer patients will experience breakthrough pain this year, based on data reported by the American Cancer Society.
"Research on breakthrough pain conducted over the past 15 years suggested that we needed to look beyond conventional short-acting opioids and evaluate new medications that could better manage the rapid onset of this often debilitating condition," said Russell Portenoy, MD, Chairman, Department of Pain Medicine and Palliative Care, Beth Israel Medical Center, in New York City, and a principal investigator in the FENTORA clinical trials. "The clinical trials of FENTORA confirm that it is safe and effective for cancer-related breakthrough pain, and may relieve pain faster than orally ingested opioids."
Conventional short-acting oral opioids, often used to treat breakthrough pain, are swallowed and absorbed in the gastrointestinal tract, which can take up to 30-45 minutes to take effect. With FENTORA's drug delivery technology, approximately half of the medicine is absorbed directly across the lining of the upper cheek, the buccal mucosa, and into the bloodstream more quickly than if it were swallowed and broken down by the liver in the gastrointestinal tract.
In placebo-controlled clinical trials, patients treated with FENTORA showed a statistically significant improvement on the primary end point, the Sum of Pain Intensity Differences (SPID30) (p<0.01) and some patients experienced clinically significant decreases in pain intensity and greater pain relief within 15 minutes, the first time point measured. In addition, pharmacokinetic data indicate that systemic exposure to fentanyl occurred earlier and was approximately 30 percent greater with FENTORA than with ACTIQ® (oral transmucosal fentanyl citrate) [C-II]. As such, FENTORA delivers the therapeutic benefit of fentanyl at a lower dose than ACTIQ.
Cephalon will manufacture FENTORA in five dosage strengths: 100, 200, 400, 600, and 800 micrograms (mcg). FENTORA will be packaged in cartons containing twenty-eight tablets (seven child-resistant blister cards with four tablets in each card).
FENTORA is the first tablet formulation of the opioid fentanyl and the first new medication approved for the management of breakthrough pain in opioid-tolerant patients with cancer since 1998. Its proprietary OraVescent® drug delivery system was developed by Cephalon subsidiary CIMA LABS. FENTORA is covered by patents until 2019.
The sugar-free FENTORA tablet is placed between the upper cheek and gum above a rear molar tooth. When it comes into contact with saliva, FENTORA's delivery system generates a reaction leading to the release of carbon dioxide. It is believed that transient pH changes accompanying this reaction may optimize how well the tablet dissolves and how quickly the medicine passes across the buccal mucosa.
In clinical trials, FENTORA was generally well tolerated. Most adverse events occurring with FENTORA are typical opioid side effects. The most serious adverse events associated with all opioids are respiratory depression (potentially leading to apnea or respiratory arrest), circulatory depression, hypotension, and shock. All patients should be followed for symptoms of respiratory depression. Opioid side effects should be expected and managed accordingly. The most common (greater than or equal to 10%) adverse events observed in clinical trials of FENTORA were nausea, vomiting, application site abnormalities, fatigue, anemia, dizziness, constipation, edema, asthenia, dehydration, and headache. Most side effects were mild to moderate in severity. No attempt was made to correct for concomitant use of around-the-clock opioids or cancer-related symptoms.
Approximately 50 million Americans suffer from chronic pain, a condition that often consists of two distinct components: persistent pain, which is pain that is continuous throughout the day, and breakthrough pain, which is a transitory flare of moderate-to-severe pain in patients with otherwise stable persistent pain. Breakthrough pain can reach peak intensity in as little as three minutes and typically lasts for 30 to 60 minutes. It may occur during a specific activity, spontaneously with no apparent cause, or when the dose of the persistent pain medicine wears off. An estimated 64 percent of all cancer patients treated for persistent pain -- and up to 74 percent of patients treated for persistent pain from other conditions such as low back pain, diabetic neuropathy, and osteoarthritis -- will experience breakthrough pain. Breakthrough pain can have a profound impact on an individual's physical and psychological well-being and is often associated with a more severe and difficult to treat pain condition. It can increase the economic burden on both patients and the healthcare system.
IMPORTANT WARNINGS AND SAFETY INFORMATION
FENTORA contains fentanyl, an opioid agonist and a Schedule II-controlled substance, with an abuse liability similar to other opioid analgesics. FENTORA can be abused in a manner similar to other opioid agonists, legal or illicit. This should be considered when prescribing or dispensing FENTORA in situations where the physician or pharmacist is concerned about an increased risk of misuse, abuse or diversion. Schedule II opioid substances which include morphine, oxycodone, hydromorphone, oxymorphone, and methadone have the highest potential for abuse and risk of fatal overdose due to respiratory depression.
FENTORA is indicated for the management of breakthrough pain in patients with cancer who are already receiving and who are tolerant to opioid therapy for their underlying persistent cancer pain. Patients considered opioid tolerant are those who are taking at least 60 mg of oral morphine/day, at least 25 mcg of transdermal fentanyl/hour, at least 30 mg of oxycodone daily, at least 8 mg of oral hydromorphone daily or an equianalgesic dose of another opioid for a week or longer.
Because life-threatening respiratory depression could occur at any dose in opioid non-tolerant patients, FENTORA is contraindicated in the management of acute or postoperative pain. This product is not indicated for use in opioid non-tolerant patients.
Patients and their caregivers must be instructed that FENTORA contains a medicine in an amount which can be fatal to a child. Patients and their caregivers must be instructed to keep all tablets out of the reach of children. (See Information for Patients and Their Caregivers contained within the prescribing information for disposal instructions.)
Due to the higher bioavailability of fentanyl in FENTORA, when converting patients from other oral fentanyl products, including oral transmucosal fentanyl citrate (OTFC and Actiq®), to FENTORA, do not substitute FENTORA on a mcg-per-mcg basis and adjust doses as appropriate. (See DOSAGE AND ADMINISTRATION contained within the prescribing information.)
FENTORA is intended to be used only in the care of opioid tolerant cancer patients and only by healthcare professionals who are knowledgeable of and skilled in the use of Schedule II opioids to treat cancer pain.
