ITEM 8.01 - OTHER EVENTS.

DUSA Pharmaceuticals, Inc. ("DUSA") issued a press release on the morning of
October 28, 2005, attached to and made a part of this report as Exhibit 99.1,
announcing the presentation of an independent investigator study in which
complete clearance of facial acne was observed in fourteen out of fourteen
patients treated with the combination of Levulan(R) (aminolevulinic acid HCl,
ALA) and Photodynamic Therapy with long pulse dye laser for recalcitrant
inflammatory acne vulgaris of the face. DUSA issued a second press release on
the afternoon of October 28, 2005, attached to and made a part of this report as
Exhibit 99.2, correcting and further clarifying certain information contained in
the earlier release, including, but not limited to, the quotation of Dr. Macrene
Alexiades-Armenakas provided therein.

Except for historical information, each 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 potential of the
therapy as safe and effective and as an alternative to isotretinoin, belief that
the therapy deserves a full development program, the publication of the study
results and the timing thereof, and the use of the product as first line
therapy. Furthermore, the factors that may cause differing results include the
publication by third-parties of the author's study results, the regulatory
process, the funding of clinical studies necessary to seek regulatory approval,
maintenance of patents and other risks identified in DUSA's SEC filings from
time to time.
