BALTIMORE, May 7 /PRNewswire/ -- A post-hoc analysis of a Phase 3 safety study demonstrated that NUCYNTA® (tapentadol) tablets were associated with a lower incidence of nausea, vomiting and constipation when compared to oxycodone immediate release (IR) tablets in elderly patients with moderate to severe low-back or osteoarthritis pain. These data will be presented during a poster session today at the 29th Annual Scientific Meeting of the American Pain Society (APS), and are supported by PriCara®, Division of Ortho-McNeil-Janssen Pharmaceuticals, Inc., and its research affiliates, Ortho-McNeil-Janssen Scientific Affairs, L.L.C. (OMJSA) and Johnson & Johnson Pharmaceutical Research & Development, L.L.C. (J&JPRD), as well as Grunenthal GmbH.
This post-hoc analysis of the original Phase 3 study evaluated the safety profile of tapentadol IR (n=158, either 50 or 100 mg dosed every four to six hours as needed) over a 90-day period among elderly patients (greater than or equal to 65 years of age). The study also evaluated an oxycodone IR active comparator group (n=45, either 10 or 15 mg dosed every four to six hours as needed).
The analysis demonstrated that tapentadol IR was associated with lower incidences of specific gastrointestinal side effects versus oxycodone IR (46.8% vs. 68.9%, respectively) as well as lower incidences of study discontinuation due to gastrointestinal side effects versus oxycodone IR (15.8% vs. 24.4%, respectively). No significant between-age group differences in efficacy were observed for patients in the tapentadol IR group (P = 0.521 for patients less than 65 vs. patients greater than or equal to 65 years of age) or the oxycodone IR group (P = 0.987 for patients less than 65 vs. patients greater than or equal to 65 years of age).
Information regarding the original double-blind, randomized, active-control, flexible-dose, 90-day, Phase 3 study in patients greater than or equal to 18 years of age with moderate to severe low back pain or osteoarthritis pain was presented at the American Pain Society Annual Meeting in May 2008.

"Low back and osteoarthritis pain are common among patients 60 years and older," said Gary Vorsanger, M.D., Ortho-McNeil Janssen Scientific Affairs, L.L.C. "These data help illustrate that NUCYNTA® may be an important treatment option to consider for older patients with moderate to severe acute low back or osteoarthritis pain."
In the post-hoc analysis, the most common adverse events (greater than or equal to 10%) among elderly patients in either treatment group were nausea, constipation, vomiting, dizziness, somnolence, and pruritus (itching). Incidences of constipation (19.0% vs. 35.6%, respectively) and the composite of nausea and/or vomiting (30.4% vs. 51.1%, respectively) were statistically significantly lower with tapentadol IR (nominal P less than 0.05 for both comparisons) among elderly patients receiving tapentadol IR versus oxycodone IR.
The NUCYNTA® (tapentadol) immediate release tablet formulation was approved by the U.S. Food and Drug Administration (FDA) on November 20, 2008, and is available by prescription only for the relief of moderate to severe acute pain in patients 18 years of age or older. The tapentadol molecule is classified as Schedule II of the Controlled Substances Act.
NUCYNTA® binds to mu-opioid receptors and inhibits norepinephrine re-uptake. Although the exact mechanism of action is not known, these two mechanisms, which affect established pain pathways, are thought to be responsible for pain relief with NUCYNTA®.
J&JPRD announced on December 1, 2009 that it submitted a New Drug Application (NDA) to the FDA for tapentadol extended release (ER) tablets for the management of moderate to severe chronic pain in patients 18 years of age or older. The NDA is currently under review. PriCara®, Division of Ortho-McNeil-Janssen Pharmaceuticals, Inc. will market tapentadol extended release tablets in the United States when the product is approved by the FDA. The NDA filing is part of the ongoing commitment of J&JPRD and PriCara® to bring new and innovative products to patients and physicians for the treatment and management of pain.

IMPORTANT SAFETY INFORMATION FOR NUCYNTA® (tapentadol)
Like other drugs with mu-opioid agonist activity, NUCYNTA® is contraindicated in patients with significant respiratory depression, acute or severe bronchial asthma or hypercapnia (excessive carbon dioxide in the blood) in unmonitored settings or in the absence of resuscitative equipment. NUCYNTA® is contraindicated in patients who have or are suspected to have paralytic ileus. NUCYNTA® is also contraindicated in patients currently using or within 14 days of using monoamine oxidase inhibitors (MAOIs) due to potential additive effects on norepinephrine levels, which may result in adverse cardiovascular events.
Respiratory depression is the primary risk of mu-opioid agonists. Respiratory depression occurs more frequently in elderly or debilitated patients and in those suffering from conditions accompanied by hypoxia, hypercapnia, or upper airway obstruction, in whom even moderate therapeutic doses may significantly decrease pulmonary ventilation. NUCYNTA® should be administered with caution to the elderly, debilitated patients, and patients with conditions accompanied by hypoxia, hypercapnia or decreased respiratory reserve such as: asthma, chronic obstructive pulmonary disease or cor pulmonale, severe obesity, sleep apnea syndrome, myxedema, kyphoscoliosis, CNS depression, or coma. In such patients, even usual therapeutic doses of NUCYNTA® may increase airway resistance and decrease respiratory drive to the point of apnea. Alternative non-mu-opioid agonist analgesics should be considered and NUCYNTA® should be employed only under careful medical supervision at the lowest effective dose in such patients. If respiratory depression occurs, it should be treated as any mu-opioid agonist-induced respiratory depression.
Patients receiving other mu-opioid agonist analgesics, general anesthetics, phenothiazines, other tranquilizers, sedatives, hypnotics, or other CNS depressants (including alcohol) concomitantly with NUCYNTA® may exhibit additive CNS depression. Interactive effects resulting in respiratory depression, hypotension, profound sedation, coma or death may result if these drugs are taken in combination with NUCYNTA®. When such combined therapy is contemplated, a dose reduction of one or both agents should be considered.
Opioid analgesics can raise cerebrospinal fluid pressure as a result of respiratory depression with carbon dioxide retention. Therefore, NUCYNTA® should not be used in patients susceptible to the effects of raised cerebrospinal fluid pressure such as those with head injury and increased intracranial pressure. Opioid analgesics may obscure the clinical course of patients with head injury due to effects on pupillary response and consciousness. NUCYNTA® should be used with caution in patients with head injury, intracranial lesions, or other sources of preexisting increased intracranial pressure.
NUCYNTA® is a mu-opioid agonist and is a Schedule II controlled substance. Such drugs are sought by drug abusers and people with addiction disorders. Diversion of Schedule II products is an act subject to criminal penalty. NUCYNTA® can be abused in a manner similar to other mu-opioid agonists, legal or illicit. This should be considered when prescribing or dispensing NUCYNTA® in situations where the physician or pharmacist is concerned about an increased risk of misuse and abuse. All patients treated with mu-opioid agonists require careful monitoring for signs of abuse and addiction. NUCYNTA® may be abused by crushing, chewing, snorting or injecting the product. These practices pose a significant risk to the abuser that could result in overdose and death.
Experience with NUCYNTA® overdose is very limited. Management of overdose should be focused on treating symptoms of mu-opioid agonism. Primary attention should be given to reestablishment of a patent airway and institution of assisted or controlled ventilation when overdose of NUCYNTA® is suspected. Supportive measures (including oxygen and vasopressors) should be employed in the management of circulatory shock and pulmonary edema accompanying overdose as indicated. Cardiac arrest or arrhythmias may require cardiac massage or defibrillation.
Patients should be cautioned that NUCYNTA® may impair the mental and/or physical abilities required for the performance of potentially hazardous tasks such as driving a car or operating machinery. This is to be expected especially at the beginning of treatment, at any change of dosage as well as in combination with alcohol or tranquilizers.
NUCYNTA® has not been systematically evaluated in patients with a seizure disorder, and such patients were excluded from clinical studies. NUCYNTA® should be prescribed with care in patients with a history of a seizure disorder or any condition that would put the patient at risk of seizures.
The development of a potentially life-threatening serotonin syndrome may occur with use of SNRI products, including NUCYNTA®, particularly with concomitant use of serotonergic drugs such as SSRIs, SNRIs, TCAs, MAOIs and triptans, and with drugs which impair metabolism of serotonin (including MAOIs). Serotonin syndrome may include mental-status changes (e.g., agitation, hallucinations, coma), autonomic instability (e.g., tachycardia, labile blood pressure, hyperthermia), neuromuscular aberrations (e.g., hyperreflexia, incoordination) and/or gastrointestinal symptoms (e.g., nausea, vomiting, diarrhea).
Withdrawal symptoms may occur if NUCYNTA® is discontinued abruptly. These symptoms may include: anxiety, sweating, insomnia, rigors, pain, nausea, tremors, diarrhea, upper respiratory symptoms, piloerection, and rarely, hallucinations. Withdrawal symptoms may be reduced by tapering NUCYNTA®.
Pregnancy Category C. There are no adequate and well-controlled studies of NUCYNTA® in pregnant women. NUCYNTA® should be used during pregnancy ONLY if the potential benefit justifies the potential risk to the fetus. NUCYNTA® is not recommended for use in women during and immediately prior to labor and delivery. Neonates whose mothers have been taking NUCYNTA® should be monitored for respiratory depression. NUCYNTA® should not be used during breastfeeding.
NUCYNTA® is not recommended in patients with severe renal or hepatic impairment. NUCYNTA® should be used with caution in patients with moderate hepatic impairment. Like other drugs with mu-opioid agonist activity, NUCYNTA® may cause spasm of the sphincter of Oddi and should be used with caution in patients with biliary tract disease, including acute pancreatitis.
The most common adverse events are nausea, dizziness, vomiting, somnolence and headache.
