Indivior Inc. Receives a Paragraph IV Notice of Certification Letter (‘PIV Notice’) from Teva Pharmaceuticals USA, Inc.02.10.2016 | PDF Version
FOR IMMEDIATE RELEASE
On or about the 10th February 2016, Indivior Inc. (‘Indivior’) received a Paragraph IV notice of certification letter (‘PIV Notice’) from Teva Pharmaceuticals USA, Inc. (‘Teva’), indicating that Teva has submitted a 505(b)(2) New Drug Application (‘NDA’) to the U.S. Food & Drug Administration (‘FDA’) seeking FDA approval to engage in the commercial manufacture, use or sale of a generic 16mg/4mg formulation of Indivior’s Suboxone® sublingual film product. Teva is already amongst the six ANDA filers to serve a PIV Notice on Indivior regarding Suboxone® sublingual film; this latest notice adds a new dosage strength to the range in its previous PIV notice.
In its PIV Notice, Teva asserts that it is seeking approval of its NDA before the expiration of Indivior’s three Orange Book listed patents (U.S. Patent Nos. 8,017,150; 8,603,514; and 8,475,832) for Suboxone® sublingual film, on the basis that these patents are not valid, enforceable and/or will not be infringed by Teva’s generic products.
Indivior’s Orange Book listed patents have expiration dates of February 13, 2023; April 3, 2024; and March 26, 2030. The Company intends to assert and enforce its intellectual property against Teva and will initiate a patent infringement lawsuit against Teva within 45-days of having received the PIV Notice, which will trigger the automatic stay of FDA approval of Teva’s 505(b)(2) NDA pursuant to the Hatch Waxman statute.

SUBOXONE® (buprenorphine and naloxone) Sublingual Film (CIII) is a prescription medicine indicated for treatment of opioid dependence and should be used as part of a complete treatment plan to include counseling and psychosocial support.
Treatment should be initiated under the direction of physicians qualified under the Drug Addiction Treatment Act.
Important Safety Information
Do not take SUBOXONE Film if you are allergic to buprenorphine or naloxone as serious negative effects, including anaphylactic shock, have been reported.
SUBOXONE Film can be abused in a manner similar to other opioids, legal or illicit.
SUBOXONE Film contains buprenorphine, an opioid that can cause physical dependence with chronic use. Physical dependence is not the same as addiction. Your doctor can tell you more about the difference between physical dependence and drug addiction. Do not stop taking SUBOXONE Film suddenly without talking to your doctor. You could become sick with uncomfortable withdrawal symptoms because your body has become used to this medicine.
SUBOXONE Film can cause serious life‐threatening breathing problems, overdose and death, particularly when taken by the intravenous (IV) route in combination with benzodiazepines or other medications that act on the nervous system (ie, sedatives, tranquilizers, or alcohol). It is extremely dangerous to take nonprescribed benzodiazepines or other medications that act on the nervous system while taking SUBOXONE Film.
You should not drink alcohol while taking SUBOXONE Film, as this can lead to loss of consciousness or even death.
Death has been reported in those who are not opioid dependent. Your doctor may monitor liver function before and during treatment.
SUBOXONE Film is not recommended in patients with severe hepatic impairment and may not be appropriate for patients with moderate hepatic impairment. However, SUBOXONE Film may be used with caution for maintenance treatment in patients with moderate hepatic impairment who have initiated treatment on a buprenorphine product without naloxone.
Keep SUBOXONE Film out of the sight and reach of children. Accidental or deliberate ingestion of SUBOXONE Film by a child can cause severe breathing problems and death.
Do not take SUBOXONE Film before the effects of other opioids (eg, heroin, hydrocodone, methadone, morphine, oxycodone) have subsided as you may experience withdrawal symptoms.
Injecting SUBOXONE may cause serious withdrawal symptoms such as pain, cramps, vomiting, diarrhea, anxiety, sleep problems, and cravings.
Before taking SUBOXONE Film, tell your doctor if you are pregnant or plan to become pregnant. If you are pregnant or become pregnant while taking SUBOXONE Film, alert your doctor immediately and you should report it using the contact information provided below.*
Neonatal withdrawal has been reported following the use of buprenorphine by the mother during pregnancy.
Before taking SUBOXONE Film, talk to your doctor if you are breastfeeding or plan to breastfeed your baby. SUBOXONE can pass into your breast milk. You and your doctor should consider the development and health benefits of breastfeeding along with your clinical need for SUBOXONE Film and should also consider any potential adverse effects on the breastfed child from the drug or from the underlying maternal condition.
Do not drive, operate heavy machinery, or perform any other dangerous activities until you know how SUBOXONE Film affects you. Buprenorphine in SUBOXONE Film can cause drowsiness and slow reaction times during dose‐adjustment periods.
Common side effects of SUBOXONE Film include nausea, vomiting, drug withdrawal syndrome, headache, sweating, numb mouth, constipation, painful tongue, redness of the mouth, intoxication (feeling lightheaded or drunk), disturbance in attention, irregular heartbeat, decrease in sleep, blurred vision, back pain, fainting, dizziness, and sleepiness.
This is not a complete list of potential adverse events associated with SUBOXONE Film. Please see full Prescribing Information for a complete list.
