Singapore: US-based Orexo has received US FDA approval for Zubsolv (buprenorphine/naloxone) sublingual tablet CIII. Zubsolv is indicated for use as maintenance treatment for people suffering from opioid dependence and should be used as part of a complete treatment plan to include counselling and psychosocial support.
Zubsolv is a once-daily, sublingual tablet with an advanced formulation of buprenorphine and naloxone that fully dissolves within minutes. Compared with other buprenorphine/naloxone treatments, Zubsolv has higher bioavailability, faster dissolve time, and smaller tablet size with a new menthol taste.
Opioid dependence affects nearly five million people across the United States. Although it is a treatable condition only 20 percent of Americans suffering from opioid dependence receive treatment today. Orexo provides with Zubsolv an additional treatment choice with new unique product features that may be important for attracting and retaining more patients in treatment for opioid dependence.
"Orexo has developed Zubsolv as a novel sublingual therapy meeting the needs of millions of patients that suffers from opioid dependence to offer them a new choice of treatment. Zubsolv has in previous studies showed a high acceptability compared to the leading treatment modalities in the market. We expect Zubsolv will be well received by patients and prescribers and we anticipate a peak market potential of at least $500M," said Mr Nikolaj Sørensen, president and CEO, Orexo.
He continued adding, "The approval of Zubsolv, which is based on our advanced formulation capabilities and developed using our proprietary technology, is a great tribute to the world class pharmaceutical formulation team at Orexo."
Opioid dependence greatly impacts the US economy, with about $56 billion spent on the disease per year. In addition, the average healthcare cost per patient with opioid dependence is eight times higher compared to nondependent patients. There is also a great impact on human life, with almost 17,000 deaths from opioid pain relievers in the U.S. every year.
"In addiction medicine, the recovery process can be challenging. Products designed to meet patient preferences have the potential to more successfully support their recovery," said Dr Louis E Baxter, past president of the American Society of Addiction Medicine. "The approval of Zubsolv provides a new treatment option that offers unique advantages specifically designed to meet the unmet needs expressed by patients and has the potential to improve patient adherence, thereby reducing relapse rates and improving successful patient outcomes."
Orexo's proprietary technology relating to Zubsolv is protected by patents and patent applications in the US and other markets worldwide. Projected expiry dates for this IP range from 2019-32.
