Titan Receives Approval For Second Year Of NIDA Grant Funding For Development Of A Nalmefene Implant
Changes in Grant Terms Result in Additional $2 Million Available to Titan for Nalmefene Project Expenses
SOUTH SAN FRANCISCO, Calif., Sept. 18, 2019 /PRNewswire/ -- National Institutes of Health's National Institute on Drug Abuse (NIDA) has approved approximately $6.1 million in second-year funding for Titan's non-clinical development of a ProNeura™ based six-month implantable formulation of Nalmefene, an opioid antagonist, intended for the prevention of relapse to opioid addiction, following opioid detoxification.
NIDA awarded Titan a two-year grant in the amount of $6.7 million in September 2018 for the project, subject to satisfactory project progress, fund availability and certain other conditions. The award for the first year, which ended August 31, 2019, was approximately $2.7 million. As a result of a change in the grant award terms regarding company matching funds, the second-year award covers both the Federal and company match amounts of the original year two award, thereby increasing the aggregate potential expense reimbursement to approximately $8.7 million.
"We believe our ProNeura technology is well-suited to this approach to treating opioid addiction, so we are grateful for NIDA's ongoing support," said Titan's President and CEO, Sunil Bhonsle. "As we continue to execute on the program's development milestones, we are encouraged by the potential for additional NIDA grant funding for clinical development activities beyond the current grant's end date of September 2020."
This second-year grant award provides funds for the completion of implant formulation development, cGMP manufacturing and non-clinical studies which, if successful, are expected to support the Company's submission of a Nalmefene six-month implant Investigational New Drug Application to the U.S. Food and Drug Administration. Titan retains full commercial rights to the Nalmefene implant product.
About Titan Pharmaceuticals
Titan Pharmaceuticals, Inc. (NASDAQ: TTNP), based in South San Francisco, CA, is a commercial stage company developing proprietary therapeutics with its ProNeura™ long-term, continuous drug delivery technology. The company's lead product is Probuphine® (buprenorphine) implant, a novel and long-acting formulation of buprenorphine for the long-term maintenance treatment of opioid dependence. Approved by the U.S. Food and Drug Administration in May 2016, Probuphine is the first and only commercialized treatment of opioid dependence to provide continuous, around-the-clock blood levels of buprenorphine for six months following a single procedure. The ProNeura technology also has the potential to be used in developing products for treating other chronic conditions such as Parkinson's disease and hypothyroidism, where maintaining consistent, around-the-clock blood levels of medication may benefit the patient and improve medical outcomes. For more information about Titan, please visit www.titanpharm.com.
Probuphine is the only subdermal implant designed to deliver buprenorphine continuously for six months following insertion.
Probuphine was developed using ProNeura™, the continuous drug delivery system developed by Titan that consists of a small, solid implant made from a mixture of ethylene-vinyl acetate and a drug substance. The resulting construct is a solid matrix that is placed subdermally, normally in the upper arm, in an outpatient office procedure and removed in a similar manner at the end of the treatment period. The U.S. Food and Drug Administration ("FDA") approved Probuphine in May 2016, and it is the first and only buprenorphine implant available for the maintenance treatment of opioid addiction in eligible patients.
