SOUTH SAN FRANCISCO, CA--(Marketwired - Mar 3, 2014) - Titan Pharmaceuticals, Inc. (
"We are pleased that there is general agreement on the clinical study," said Dr. Kate Glassman-Beebe, executive vice president and chief development officer. "This study design provides the best opportunity for an unbiased comparison of treatment with Probuphine to the current standard of care practice, while making sure all patients will receive active treatment for the disease."
Titan and Braeburn submitted a detailed clinical study synopsis to the FDA several weeks ago, following discussions with the FDA in November 2013 regarding the Complete Response Letter issued to the Probuphine NDA. These discussions and feedback from the FDA led to the study design described above.
About Opioid Dependence
According to recent estimates, there are 2.2 million people with opioid dependence in the U.S. Approximately 20 percent of this population is addicted to illicit opioids, such as heroin, and the other 80 percent to prescription opioids, such as oxycodone, hydrocodone, methadone, hydromorphone and codeine. Before the year 2000, medication-assisted therapies for opioid dependence had been sanctioned to a limited number of facilities in the U.S. The Drug Addiction Treatment Act of 2000 (DATA 2000) allowed medical office-based treatment of opioid dependence and greatly expanded patient access to medication-assisted treatments. As a result, an estimated 1.2 million people in the U.S. sought treatment for opioid dependence in 2011.
Probuphine is an investigational subdermal implant designed to deliver continuous, around the clock blood levels of buprenorphine for six months following a single treatment, and to simplify patient compliance and retention. Buprenorphine, an approved agent for the treatment of opioid dependence, is currently available in the form of daily dosed sublingual tablets and film formulations, with reported 2012 sales of $1.5 billion in the United States.
Probuphine was developed using ProNeura™, Titan's continuous drug delivery system that consists of a small, solid implant made from a mixture of ethylene-vinyl acetate (EVA) and a drug substance. The resulting construct is a solid matrix that is placed subdermally, normally in the upper arm in a simple office procedure, and removed in a similar manner at the end of the treatment period. The drug substance is released slowly and continuously through the process of dissolution resulting in a steady rate of release.
The efficacy and safety of Probuphine has been studied in several clinical trials, including a 163-patient, placebo-controlled study over a 24-week period (published in the Journal of the American Medical Association (JAMA)), and a follow on study of 287 patients (published in the journal Addiction).
