Zohydro ER With BeadTek(TM) to be Available in the Second Quarter of 2015
SAN DIEGO, Jan. 30, 2015 (GLOBE NEWSWIRE) -- Zogenix, Inc. (Nasdaq:ZGNX), a pharmaceutical company developing and commercializing products for the treatment of central nervous system (CNS) disorders, today announced that the U.S. Food and Drug Administration (FDA) has approved a new formulation of Zohydro® ER (hydrocodone bitartrate) Extended-Release Capsules, CII, with BeadTek™. BeadTek is a formulation technology designed to provide abuse-deterrent properties without changing the release properties of hydrocodone when Zohydro ER is used as intended. Concurrently, Zogenix has ongoing Human Abuse Liability studies, which will further characterize the abuse-deterrent properties of the new formulation. Zogenix intends to submit these data in the second half of 2015 to the FDA to support an amended product label, including abuse-deterrent claims consistent with the FDA's current draft Guidance for Industry, Abuse-Deterrent Opioids – Evaluation and Labeling.
BeadTek incorporates well-known pharmaceutical excipients that immediately form a viscous gel when crushed and dissolved in liquids or solvents. Zohydro ER is the only long-acting hydrocodone product administered every 12 hours, and the new formulation maintains the same efficacy and pharmacokinetic profile of the original formulation. Transition to Zohydro ER with BeadTek is expected to occur in the second quarter of 2015 for all prescribed strengths ranging from 10 mg to 50 mg, without disruption to patients currently on therapy.
"While we are very pleased with the outcomes from our safe use initiatives, implemented with the introduction of Zohydro ER last year, we believe moving forward with this formulation change at the earliest possible time is a responsible action for us to take," said Stephen Farr, Ph.D., president of Zogenix. "We are also committed to completing the ongoing studies to seek additional changes in the product label relating to abuse-deterrent properties by the end of the year."
Zohydro ER is indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate. Zohydro ER does not contain acetaminophen, unlike many immediate-release hydrocodone products, reducing the risk for potential liver toxicity due to overexposure of acetaminophen.
BeadTek was developed using safe, well-known excipients and proprietary manufacturing processes to create an inactive ingredient that immediately forms a viscous gel when crushed and dissolved in liquids or solvents. All of the beads within the medication capsule are indistinguishable in color, shape, density and size, and do not impact the drug release profile when taken as directed.
Zohydro® ER is an extended-release opioid agonist indicated for the management of pain severe enough to require daily, around-the-clock, long-term opioid treatment and for which alternative treatment options are inadequate.
LIMITATIONS OF USE
Because of the risks of addiction, abuse, and misuse with opioids, even at recommended doses, and because of the greater risks of overdose and death with extended-release opioid formulations, reserve Zohydro ER for use in patients for whom alternative treatment options (e.g., non-opioid analgesics or immediate-release opioids) are ineffective, not tolerated, or would be otherwise inadequate to provide sufficient management of pain.
Zohydro ER is not indicated as an as‑needed (prn) analgesic.
Please see the Zohydro ER full prescribing information for the complete boxed warning and safety information.
WARNING: ADDICTION, ABUSE, AND MISUSE; LIFE-THREATENING RESPIRATORY DEPRESSION; ACCIDENTAL INGESTION; NEONATAL OPIOID WITHDRAWAL SYNDROME; INTERACTION WITH ALCOHOL; and CYTOCHROME P450 3A4 INTERACTION
See full prescribing information for complete boxed warning.
ZOHYDRO ER exposes users to risks of addiction, abuse, and misuse, which can lead to overdose and death. Assess each patient's risk before prescribing, and monitor regularly for development of these behaviors or conditions.
Serious, life-threatening, or fatal respiratory depression may occur. Monitor closely, especially upon initiation or following a dose increase. Instruct patients to swallow ZOHYDRO ER whole to avoid exposure to a potentially fatal dose of hydrocodone.
Accidental ingestion of ZOHYDRO ER, especially in children, can result in a fatal overdose of hydrocodone.
Prolonged use of ZOHYDRO ER during pregnancy can result in neonatal opioid withdrawal syndrome, which may be life-threatening if not recognized and treated. If opioid use is required for a prolonged period in a pregnant woman, advise the patient of the risk of neonatal opioid withdrawal syndrome and ensure that appropriate treatment will be available.
Instruct patients not to consume alcohol or any products containing alcohol while taking ZOHYDRO ER because co-ingestion can result in fatal plasma hydrocodone levels.
Initiation of CYP3A4 inhibitors (or discontinuation of CYP3A4 inducers) can result in a fatal overdose of hydrocodone from ZOHYDRO ER.
IMPORTANT SAFETY INFORMATION
Zohydro ER is contraindicated in patients with significant respiratory depression, acute or severe bronchial asthma, known or suspected paralytic ileus, and hypersensitivity to hydrocodone bitartrate.
Zohydro ER has warnings for: interactions with CNS depressants; elderly, cachectic, debilitated patients, and those with chronic pulmonary disease; hypotensive effects; patients with head injury or increased intracranial pressure; and concomitant use of CYP3A4 may increase opioid effects. Please see full prescribing information for the complete warning information.
Potential serious adverse events caused by opioids include addiction, abuse, and misuse; life-threatening respiratory depression; neonatal opioid withdrawal syndrome; interactions with other CNS depressants; hypotensive effects; gastrointestinal conditions, and seizures. The most common adverse reactions associated with Zohydro ER (≥2%) include constipation, nausea, somnolence, fatigue, headache, dizziness, dry mouth, vomiting, pruritus, abdominal pain, peripheral edema, upper respiratory tract infection, muscle spasms, urinary tract infection, back pain, and tremor. With intravenous abuse, the inactive ingredients in Zohydro ER can result in death, local tissue necrosis, infection, pulmonary granulomas, and increased risk of endocarditis and valvular heart injury. Parenteral drug abuse is commonly associated with transmission of infectious diseases such as hepatitis and HIV.
