Cephalon, Inc. (Nasdaq: CEPH) today announced positive results from a 12-week, Phase 3 clinical trial of FENTORA(R) (fentanyl buccal tablet) [C-II] in patients with breakthrough pain associated with a broad range of chronic non-cancer pain conditions. The study achieved statistical significance on the primary endpoint. Results across the 12 weeks of treatment showed both statistically significant and clinically relevant outcomes for patients with breakthrough pain who were already receiving and who were tolerant to opioid therapy for their underlying persistent pain. FENTORA is approved only 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.

"We are excited to complete our Phase 3 program with this third and final controlled study. These data show similar positive outcomes as those with FENTORA in treating breakthrough pain in opioid-tolerant patients with cancer, chronic neuropathic pain, and chronic low-back pain," said Dr. Lesley Russell, Executive Vice President, Worldwide Medical and Regulatory Operations. "We plan to submit these data to the Food and Drug Administration in the fourth quarter as part of our supplemental New Drug Application."

The double-blind, placebo-controlled, variable dose Phase 3 trial included 148 patients. The primary endpoint was the Sum of Pain Intensity Differences from five to 60 minutes (SPID(60)) as assessed after 12 weeks of treatment. SPID(60) is a measure that assesses analgesic efficacy of a pain medication over the first 60 minutes after treatment. Patients treated with FENTORA showed a statistically significant improvement on the primary endpoint (p<0.0001) compared with placebo. FENTORA was generally well tolerated by the study participants with side effects consistent with those in the currently approved label. The company plans to present the data at a major medical meeting in the future.

Breakthrough pain is a component of chronic pain that is characterized by its rapid onset, moderate to severe intensity, and relatively short duration. Breakthrough pain has an average onset of three to five minutes and typically lasts 30 to 60 minutes.

FENTORA is indicated only for the management of breakthrough pain in patients with cancer who are already receiving and who are tolerant to opioid therapy, as described below in the FENTORA label, for their underlying persistent cancer pain. FENTORA incorporates a drug delivery system that generates transient changes in pH, which may optimize how well the tablet dissolves and how quickly the medicine passes across the lining of the cheek, or buccal mucosa. 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. The most common (greater than or equal to 10 percent) adverse events observed in FENTORA cancer clinical trials were nausea, dizziness, vomiting, fatigue, headache, constipation, anemia, somnolence, and peripheral edema. Most adverse events were mild to moderate in severity. No attempt was made to correct for concomitant use of around-the-clock opioids or cancer-related symptoms. In addition, application site reactions were reported in nine percent of patients, tended to occur early on treatment, and resulted in treatment discontinuation in only two percent of patients.

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 only 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 nontolerant 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 Caregivers 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(R)), to FENTORA, do not substitute FENTORA on a mcg per mcg basis. Adjust doses as appropriate. (See DOSAGE AND ADMINISTRATION.)

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.

The concomitant use of FENTORA with strong and moderate cytochrome P450 3A4 inhibitors may result in an increase in fentanyl plasma concentrations, and may cause potentially fatal respiratory depression.
