ITEM 8.01 - OTHER EVENTS.

DUSA Pharmaceuticals, Inc. (the "Company") issued a press release on February 1,
2006, attached to and made a part of this report as Exhibit 99, reporting the
results from its multi-center Phase II clinical study of photodynamic therapy
(PDT) using DUSA's Levulan(R) (aminolevulinic acid HCl, ALA) Kerastick(R) in
combination with the Company's BLU-U(R) (Blue Light Photodynamic Therapy
Illuminator), versus BLU-U with vehicle, for the treatment of moderate to severe
acne vulgaris of the face.

Except for historical information, this report, including the attached news
release, 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 the
Company's beliefs regarding the statistical significance of certain results, the
usefulness for design of future trials, and confirmation of use of the BLU-U.
Furthermore, the factors that may cause differing results include the
uncertainties of conducting new clinical trials, the regulatory approval
process, the marketplace acceptance of the Company's products, sufficient
funding to conduct new trials, product development risks, maintenance of the
Company's patent portfolio, reliance on third party manufacturers, and other
risks identified in DUSA's SEC filings from time to time.
