Probuphine is a novel, subcutaneous implant formulation of buprenorphine using Titan's ProNeura technology to deliver six months of medication after a single administration.

These data will be presented during a special breakfast symposium at the meeting on Wednesday, November 19, 2008 at 7 a.m. local time: "An Implantable, Six-Month, Sustained-Release Formulation of Buprenorphine: Phase 3 Efficacy and Safety Results." The chairman of this session is Dr. Walter Ling, Professor-in-Residence of Psychiatry and Director of the Integrated Substance Abuse Programs (ISAP) at UCLA, and the co-chairman is Dr. Solomon Rataemane, Convenor of ISAM 2008 and Chairperson of the Department of Psychiatry at the University of Limpopo (Medical University of South Africa). The session will include the following presentations:

About Probuphine

Probuphine, which is currently in development for the treatment of opioid addiction, is a small solid rod made from a mixture of ethylene-vinyl acetate (EVA) and buprenorphine that is designed to provide continuous, non-fluctuating, long-term therapeutic levels of the drug buprenorphine for six months after a single administration. Buprenorphine, an approved agent for the treatment of opioid addiction, is sold mainly in the form of a sublingually delivered tablet under the brand names Suboxone(R) (buprenorphine HCl/nalaxone HCl dehydrate) and Subutex(R) (buprenorphine HCl) with worldwide sales estimated at $0.5 billion.

About Titan Pharmaceuticals

Titan Pharmaceuticals, Inc. (AMEX: TTP) is focused primarily on the late-stage development and commercialization of Probuphine, which utilizes Titan's proprietary ProNeura long term drug delivery technology, and has demonstrated positive results in Phase 3 testing for treatment of opiate addiction. Products based on ProNeura technology can provide controlled drug release on an outpatient basis over extended periods of up to 6-12 months and may be useful for other potential treatment applications in which conventional treatment is limited by variability in blood drug levels and poor patient compliance. Titan also has two other products, gallium maltolate and DITPA, in earlier stages of development. For more information, please visit the Company's website at
