Management Comments:

“We are excited to report the improvement in many of our key financial indicators this quarter,” stated Robert Doman, President and CEO. “The combination of strong top line PDT revenue growth, the achievement of record Kerastick margins, and reductions in our overall spending drove our non-GAAP loss to a record low point.”

“We experienced significant growth in Kerastick revenue during the third quarter. This is due in part to solid execution by the sales and marketing team and a 33% increase in BLU-U volume year-to-date. This represents the 16th consecutive quarter of year over year domestic Kerastick growth.”

“In October, we announced an important milestone in the Company’s history, having surpassed cumulative Kerastick sales of one million units. The achievement of this milestone demonstrates the relevance that PDT is gaining in the medical dermatology community,” continued Doman.

“For the remainder of the year, we will focus our efforts on further capitalizing on the significant growth potential that exists for Levulan PDT in the treatment of actinic keratoses (AKs),” concluded Doman.

Third Quarter 2009 Financial Results:

Total product revenues were $6.9 million in the third quarter of 2009, up 21% from $5.7 million in the third quarter of 2008. PDT revenues totaled $6.7 million, up $1.5 million, or 30%, from $5.2 million for the comparable 2008 period. The increase in PDT revenues was attributable to a 32% increase in Kerastick® revenues and a 7% increase in BLU-U® revenues. The Kerastick® revenue improvement was driven by a 20% increase in our domestic Kerastick® volume and an overall 10% increase in our average selling price. Kerastick® sales volumes increased to 53,622 in the third quarter of 2009 from 44,668 units sold in the third quarter of 2008. Domestic Kerastick® sales volumes increased by 7,938 units, or 20%, and were supplemented by a 1,016 unit increase in our international sales volumes. The BLU-U® revenue increase was driven by a 4% increase in sales volume. There were 59 units sold during the quarter, as compared to the prior year quarterly total of 57 units. Non-PDT revenues totaled $0.2 million versus $0.6 million for the comparable 2008 period. Non-PDT revenues were adversely impacted by the absence of Nicomide® royalty revenues in 2009. DUSA has not received the installment payments due under its exclusive Nicomide® patent license agreement with River’s Edge since June 2009. The Company is currently evaluating its options to collect the amounts due from River’s Edge.

DUSA’s net loss on a GAAP basis for the third quarter of 2009 was ($0.4) million, or ($0.02) per common share, compared to a net loss of ($2.8) million, or ($0.12) per common share, in the third quarter of 2008.

DUSA’s non-GAAP net loss for the third quarter of 2009, after adjustments for stock-based compensation expense, consideration provided to the former Sirius shareholders, and the non-cash change in fair value of warrants, was ($0.2) million, or ($0.01) per common share, compared to a net loss of ($1.6) million, or ($0.07) per common share, in the prior year period. The decrease in the Company’s net loss was primarily the result of the year over year increase in our PDT revenues and lower operating costs due to the absence of spending on our Phase IIb acne clinical trial which concluded in 2008.

Please refer to the section entitled “Use of Non-GAAP Financial Measures” and the accompanying financial table included at the end of this release for a reconciliation of GAAP to non-GAAP results for the three and nine month periods ending September 30, 2008 and 2009, respectively.

Year-to-Date 2009 Financial Results:

Total product revenues for the nine month period ended September 30, 2009 were $21.0 million, down 3% from $21.8 million in comparable prior year period. PDT revenues totaled $19.8 million, up $3.4 million, or 21% from $16.4 million for the comparable 2008 period. The increase in PDT revenues was attributable to a 20% increase in Kerastick® revenues and a 26% increase in BLU-U® revenues. The Kerastick® revenue improvement was driven by a 13% increase in our domestic Kerastick® volume and an overall 13% increase in our average selling price. Kerastick® sales volumes increased to 155,384 in 2009 from 145,256 units sold in 2008. Domestic Kerastick® sales volumes increased by 15,966 units, or 13%, and were partially offset by a 5,838 unit decrease in our international sales volumes. The BLU-U® revenue increase was driven by a 29% increase in sales volume. There were 198 units sold during in 2009, representing a 44 unit increase over the prior year total of 154 units. Non-PDT revenues totaled $1.2 million versus $5.4 million for the comparable 2008 period. Non-PDT revenues were adversely impacted by the absence of Nicomide® sales in 2009. In response to discussions with the Food and Drug Administration (FDA) regarding our marketing of certain products considered by the FDA to be marketed unapproved drugs, the Company stopped shipping Nicomide® into the wholesale channel in June of 2008.

DUSA’s net loss on a GAAP basis for the nine months ended September 30, 2009 was ($2.9) million or ($0.12) per common share, compared to a net loss of ($4.3) million or ($0.18) per common share in 2008.

DUSA’s non-GAAP net loss, after adjustments for stock-based compensation expense, a milestone payment made related to the Sirius acquisition, consideration provided to the former Sirius shareholders, and the non-cash change in fair value of warrants, for the nine months ending September 30, 2009 was ($1.9) million, or ($0.08) per common share, in 2009, compared to ($2.5) million, or ($0.10) per common share, in 2008. The decrease in our net loss was primarily the result of the year over year decrease in our operating costs due mainly to the absence of spending on our Phase IIb acne clinical trial which concluded in 2008, and a Prescription Drug User Fee Act (PDUFA) charge accrued in the prior year period.

As of September 30, 2009, total cash, cash equivalents, and marketable securities were $15.0 million, compared to $18.9 million at December 31, 2008.

Other Updates:

— Solid Organ Transplant Recipients Clinical Development.– In May 2009, the Company announced the initiation of its Phase IIclinical trial that is examining the safety and efficacy of PDT forthe treatment of broad area AKs and the prevention of squamous cellcarcinomas in high risk chronically immunosuppressed solid organtransplant recipients. All seven clinical sites have been initiatedand trial enrollment is currently underway.– In May 2008, DUSA filed an Orphan Drug Designation application withthe FDA with respect to the prevention of cancer occurrence in thesepatients. The Company received initial correspondence that theapplication was not granted on the basis that the agency believesthat the prevalence of the target population with the disease stateis greater than 200,000, which is the maximum number of patientsallowed under the Orphan Drug legislation. During the third quarterof 2009, DUSA met with the FDA to clarify and explain in more detailour rationale for the application and, based on that meeting, theagency has invited us to submit an amendment to our application forfurther evaluation. DUSA is in the process of drafting the amendmentand expects to submit it to the FDA later this month.

— BLU-U® Claims Expansion.– In May 2009, the Company filed a 510(k) application with the FDA toexpand the allowed claims on BLU-U® to include severe acne. Thefiling was based on the results of our Phase IIb clinical trial. Wereceived a response to our application from the FDA in June 2009.The agency requested additional information in order to complete itsreview of our application, including supplementary clinical data insupport of our claims. Based on the FDA’s requests and theanticipated costs of additional clinical trials, the Company hasdecided not to pursue the 510(k) application for an expansion of theBLU-U® claims at this time.

Use of Non-GAAP Financial Measures

In addition to reporting financial results in accordance with GAAP, DUSA has provided in the table below non-GAAP financial measures adjusted to exclude stock-based compensation expense, consideration provided to the former Sirius shareholders, and the non-cash change in fair value of warrants. The Company believes that this presentation is useful to help investors better understand DUSA’s financial performance, competitive position and prospects for the future. Management believes that these non-GAAP financial measures assist in providing a more complete understanding of the Company’s underlying operational results and trends, and in allowing for a more comparable presentation of results. Management uses these measures along with their corresponding GAAP financial measures to help manage the Company’s business and to help evaluate DUSA’s performance compared to the marketplace. However, the presentation of non-GAAP financial measures is not meant to be considered in isolation or as superior to or as a substitute for financial information provided in accordance with GAAP. The non-GAAP financial measures used by the Company may be calculated differently from, and, therefore, may not be comparable to, similarly titled measures used by other companies.

Investors are encouraged to review the reconciliations of these non-GAAP financial measures to the comparable GAAP results, contained in the table below.
