Overview

Titan Pharmaceuticals, Inc. was incorporated as a Delaware corporation in 1992. Titan previously focused on developing therapeutics utilizing the proprietary long-term drug delivery platform, ProNeura®, for the treatment of select chronic diseases for which steady state delivery of a drug has the potential to provide an efficacy and/or safety benefit. ProNeura consists of a small, solid implant made from a mixture of ethylene-vinyl acetate (“EVA”) and a drug substance. The resulting product is a solid matrix that is designed to be administered sub-dermally in a brief, outpatient procedure and is removed in a similar manner at the end of the treatment period.

Titan’s first product based on the ProNeura technology was Probuphine® (buprenorphine implant), which is approved in the United States, Canada and the European Union (“EU”) for the maintenance treatment of opioid use disorder in clinically stable patients taking 8 mg or less a day of oral buprenorphine. While Probuphine continues to be commercialized in the EU (as Sixmo™) by another company that had acquired the rights from Titan, Titan discontinued commercialization of the product in the United States during the fourth quarter of 2020 and subsequently sold the product in September 2023.

In December 2021, Titan announced its intention to work with a financial advisor to explore strategic alternatives to enhance stockholder value, potentially including an acquisition, merger, reverse merger, other business combination, sales of assets, licensing or other transaction.
