Accentia Biopharmaceuticals in Discussions with Pharmaceutical Companies on SinuNase Partnership.

SinuNase is Fast-Tracked and the First and Only Phase 3 Product for Chronic Sinusits

TAMPA, Fla. -- Accentia Biopharmaceuticals (NASDAQ: ABPI) has entered into mutual confidentiality agreements with several pharmaceutical companies that have established respiratory care franchises. These companies have approached Accentia regarding SinuNase[TM], a unique formulation of low-dose intranasal amphotericin B, in development for the treatment of chronic sinusitis. Accentia believes that potential relationships with appropriate pharmaceutical partners could provide upfront and milestone payments as well as enhance the commercial opportunity for SinuNase, especially within the primary care market in the U.S. and in international markets.

Interest from pharmaceutical companies to partner has been stimulated by the fact that Accentia has commenced a Phase 3 clinical trial for SinuNase in patients with severe chronic sinusitis that are refractory to sinus surgery. SinuNase is the first and only product in a Phase 3 clinical trial for chronic sinusitis. Moreover, SinuNase has been granted Fast-Track status by the Food and Drug Administration (FDA). There is currently no approved pharmaceutical available for chronic sinusitis, a condition that affects 31 million patients, and represents a market almost twice the size of the asthma market, which is the next largest among respiratory diseases. To date, 43 clinical trial sites have been initiated and 29 have been cleared to enroll patients.

Upon the anticipated approval of SinuNase by the FDA, Accentia plans to focus its commercial efforts using its respiratory sales force on the approximately 15,000 U.S. ear nose & throat (ENT) and allergist specialists who treat patients with the most severe cases of chronic sinusitis. These specialists are considered opinion leaders in the diagnosis and management of chronic sinusitis. Relationships with these specialists have been facilitated by Accentia's ongoing marketing of MD Turbo[TM], an FDA-cleared medical device that optimizes the use of metered dose inhalers (MDIs) for asthma patients, a condition that is found in at least 60% of chronic sinusitis patients, and CRSFungal Profile[TM] test, the only lab test available for the diagnosis of chronic sinusitis. Additionally, all of the physician investigators in the current Phase 3 trial are ENTs or allergists.
