MALVERN, Pa., May 10, 2013 /PRNewswire/ -- Endo Health Solutions Inc. (Nasdaq: ENDP) announced today that the U.S. Food and Drug Administration (FDA) has denied a Citizen Petition filed by its subsidiary, Endo Pharmaceuticals Inc. Endo presented FDA data collected from an ongoing epidemiology study that indicate that per 100,000 prescriptions dispensed, the past 30-day abuse rate of crush-resistant OPANA ER was 79 percent lower than the abuse rate of generic versions of extended-release oxymorphone that were on the market in 2012. Endo, through its Citizen Petition, requested that FDA:
- Determine that the original, non-abuse deterrent formulation of OPANA ER was withdrawn from sale for reasons of safety, as is supported, in part, by the ongoing epidemiology studies
- Refuse to approve any abbreviated new drug applications that referenced the non-abuse deterrent version of OPANA ER
- Suspend the approvals of generic formulations of OPANA ER currently on the market.
The FDA decided that the original formulation of OPANA ER was not withdrawn from the market for reasons of safety or effectiveness. As a result, generic versions of the original formulation can continue to be approved and marketed. Additionally, FDA issued a complete response to Endo's supplemental new drug application requesting the addition of labeling language describing the abuse-deterrent properties of OPANA ER.
"We are extremely disappointed and disagree with today's decision, and believe that the approval of non-abuse deterrent formulations of long acting opioids will contribute to a significant increase in prescription drug abuse," said Rajiv De Silva, president and chief executive officer of Endo Health Solutions. "With the approval and expected launch of additional non-abuse deterrent generic versions of OPANA ER, we will carefully assess Endo's position in the competitive landscape and explore all options, including those intended to mitigate the effect of this decision. Endo remains committed to patient safety, including appropriate use of our products, as a top priority."
Endo's financial guidance for 2013 included an assumption that FDA would remove generic versions of OPANA ER from the market by mid-year. In isolation, Endo estimates that the denial of the Citizen's Petition and the potential launch of multiple generic formulations of non-abuse deterrent oxymorphone could reduce 2013 total net sales of OPANA ER by up to $120 million and reduce adjusted diluted EPS by up to approximately $0.55 in 2013. However, the company is actively pursuing cost-reduction actions that will reduce the earnings effect of FDA's decision. Endo will provide an update to its 2013 guidance on or before the second quarter financial results conference call in August.
About OPANA ER OPANA ER is indicated for the relief of moderate to severe pain in patients requiring continuous, around-the-clock opioid treatment for an extended period of time. WARNING: ABUSE POTENTIAL, LIFE‐THREATENING RESPIRATORY DEPRESSION, ACCIDENTAL EXPOSURE, and INTERACTION WITH ALCOHOL
Abuse Potential OPANA ER contains oxymorphone, an opioid agonist and Schedule II controlled substance with an abuse liability similar to other opioid agonists, legal or illicit. Assess each patient's risk for opioid abuse or addiction prior to prescribing OPANA ER. The risk for opioid abuse is increased in patients with a personal or family history of substance abuse (including drug or alcohol abuse or addiction) or mental illness (e.g., major depressive disorder). Routinely monitor all patients receiving OPANA ER for signs of misuse, abuse, and addiction during treatment.
Life-threatening Respiratory Depression Respiratory depression, including fatal cases, may occur with use of OPANA ER, even when the drug has been used as recommended and not misused or abused. Proper dosing and titration are essential and OPANA ER should only be prescribed by healthcare professionals who are knowledgeable in the use of potent opioids for the management of chronic pain. Monitor for respiratory depression, especially during initiation of OPANA ER or following a dose increase. Instruct patients to swallow OPANA ER tablets whole. Crushing, dissolving, or chewing OPANA ER can cause rapid release and absorption of a potentially fatal dose of oxymorphone.
Accidental Exposure Accidental ingestion of OPANA ER, especially in children, can result in a fatal overdose of oxymorphone.
Interaction with Alcohol The co‐ingestion of alcohol with OPANA ER may result in an increase of plasma levels and potentially fatal overdose of oxymorphone. Instruct patients not to consume alcoholic beverages or use prescription or non-prescription products that contain alcohol while on OPANA ER.
