DUSA Pharmaceuticals, Inc. ("DUSA") has been informed that Actavis Totowa, LLC received a warning letter from the U.S. Food and Drug Administration ("FDA") regarding certain regulatory observations. Actavis Totowa, formerly known as Amide Pharmaceuticals, Inc., is the contract manufacturer of Nicomide(R). The primary observations noted in the warning letter were not related to Nicomide(R). However, with respect to Nicomide(R) and certain other products manufactured by Actavis Totowa, the FDA has requested that the manufacturer provide a copy of the labeling and information providing the basis for an exemption from the drug approval requirements. The FDA regulates such products under the compliance policy guide entitled, "Marketed New Drugs without Approved NDAs or ANDAs." DUSA is working with the manufacturer in order to respond appropriately to the FDA. Nicomide(R) is one of the key products DUSA acquired from Sirius Laboratories, Inc. in connection with our merger completed in March, 2006. Nicomide(R) is an oral prescription vitamin supplement. In addition, as DUSA has previously stated, certain of the Sirius products acquired in connection with the merger must meet certain minimum manufacturing and labeling standards established by the FDA and applicable to products marketed without approved marketing applications. FDA regulates such products under its marketed unapproved drugs compliance policy mentioned above. Under this policy, FDA recognizes that certain unapproved products, based on the introduction date of their active ingredients and the lack of safety concerns, have been marketed for many years and, at this time, will not be the subject of any enforcement action. We believe that so long as we comply with applicable manufacturing and labeling standards we will be consistent with FDA's current enforcement policy. There can be no assurance that the FDA will continue this policy or not take a contrary position with any individual products. If the FDA were to do so, we may be required to seek FDA approval for these products, market these products as over-the-counter products or as dietary supplements under applicable legislation, or withdraw such products from the market. Except for historical information this report contains certain forward-looking statements that involve known and unknown risk and uncertainties, which may cause actual results to differ materially from any future results, performance or achievements expressed or implied by the statements made. These forward-looking statements relate to our beliefs regarding the applicability of FDA's guidance to our products and potential ramifications thereof. Furthermore, the factors that may cause differing results include the regulatory process and environment, actions or inactions of third-parties, sources of funding, maintenance of its patent portfolio and other risks identified in DUSA's SEC filings from time to time. SIGNATURES Pursuant to the requirements of the Securities Exchange Act of 1934, the Registrant has duly caused this report to be signed on its behalf by the undersigned hereunto duly authorized.
