Biodel Reports First Quarter Fiscal Year 2009 Financial Results and Clinical Update

     — Data demonstrate bioequivalence of 100IU/cc liquid formulation of VIAject™

DANBURY, Conn., February 5, 2009 — Biodel Inc. (Nasdaq: BIOD) today reported financial results for the first quarter ended December 31, 2008 and provided an update on recent clinical findings with its lead product candidate, VIAject™.

First Quarter Fiscal Year 2009 Financial Results

Biodel reported a net loss for the quarter ended December 31, 2008 of $10.0 million, or $0.42 per share, as compared to a net loss of $11.0 million, or $0.55 per share, for the comparable period in the prior year.

Research and development expenses were $8.0 million for the three months ended December 31, 2008, compared to $7.5 million for the same period in the prior year. The increase in quarterly expenses was primarily due to costs related to commercial supply inventory, personnel, consultants and other research activities. Research and development expenses for the three months ended December 31, 2008 include $0.4 million in stock-based compensation expense related to options granted to employees and consultants.

General and administrative expenses totaled $2.3 million for the three months ended December 31, 2008, compared to $4.1 million for the same period in the prior year. The decrease was primarily attributable to one-time charges that occurred in the three months ended December 31, 2007 that consisted of a severance accrual of $1.2 million for our former chief financial officer and $0.4 million in share-based compensation for two newly appointed board members. General and administrative expenses for the three months ended December 31, 2008 include $0.8 million in stock-based compensation expense related to options granted to employees.

Biodel did not recognize any revenue during the first quarter of fiscal year 2009.

At the end of December 2008, Biodel had cash, cash equivalents and marketable securities of $81.1 million and 23.7 million shares outstanding.

Clinical Update

Biodel recently completed a single-dose bioequivalence study in 40-patients which demonstrated that the pre-mixed 100 IU/cc liquid formulation of VIAject is bioequivalent to the two-part 25 IU/cc lyophilized powder formulation of VIAject™ that was used in the company’s pivotal Phase 3 clinical trials.

The trial also compared the relative levels of injection site discomfort associated with the two formulations and found the 100 IU/cc formulation to be superior to the 25 IU/cc formulation of VIAject™. Each of the 40 patients in the trial received both the 25 IU/cc and 100 IU/cc formulation and was asked to compare the pain intensity upon injection of each formulation with the pain associated with the prandial insulin they normally use.

While 20% of the study subjects reported that the pain upon injection was “moderately” or “greatly” increased when injected with the 25 IU/cc formulation, only 5% of the subjects reported “moderately” more pain and no patients reported “greatly” more pain when injected with the 100 IU/cc formulation. Thirty percent of subjects receiving the 25 IU/cc formulation and 45% of subjects receiving the 100 IU/cc formulation reported no pain upon injection. The

balance of the study subjects reported little to no difference in pain when comparing either the 25IU/cc or 100IU/cc formulation to the prandial insulin they normally use.

Based upon these findings, the pre-mixed 100 IU/cc liquid formulation of VIAject™ is now Biodel’s preferred insulin formulation for clinical development and eventual commercial sale since it is less expensive to produce and more convenient to use with currently available insulin syringes, pen injectors and pumps.
