    NEWTON, Mass.--(BUSINESS WIRE)--March 10,
2006--Pro-Pharmaceuticals, Inc. (AMEX:PRW), a developer of novel
carbohydrate-based therapeutic compounds, today reported its unaudited
fourth quarter and full year 2005 financial results, ended December
31, 2005.
    For the fourth quarter of 2005, the Company reported a net loss of
$1,749,000, or $0.07 per share, compared with a net loss of
$2,158,000, or $0.07 per share, for the same period in 2004. For the
full year 2005, the Company reported a net loss of $6,544,000, or
$0.24 per share, compared with a net loss of $7,180,000, or $0.28 per
share, for the 2004 fiscal year.
    At December 31, 2005, the Company had cash and cash equivalents of
approximately $4.5 million. On February 14, 2006, the Company
completed a private placement of convertible debentures and warrants
with institutional investors and raised net proceeds of approximately
$9.3 million. With the addition of these funds, the Company believes
it has adequate cash to fund its operations through at least June
2007.
    "We continue to make progress towards our goal to develop and
commercialize our proprietary carbohydrate-based therapeutic
compounds," said David Platt, Ph.D., Chief Executive Officer,
Pro-Pharmaceuticals. "We successfully completed a Phase I trial of our
lead compound, DAVANAT(R), alone and in combination with 5-FU, a
widely used, FDA-approved chemotherapy agent. We have an ongoing Phase
II trial in the U.S. for third- and fourth-line treatment of patients
with colorectal cancer. We initiated a Phase II trial for first-line
treatment of patients with cholangiocarcinoma (bile duct cancer) and
we initiated a European-based Phase III trial for second-line
treatment of patients with colorectal cancer. We continue to develop
and expand our product pipeline. We believe our expertise in
carbohydrates offers opportunities to provide advanced treatment of
cancer, liver, microbial, cardiovascular, and inflammatory diseases,
as well as viral infections."
    Research and development expense for the full year 2005 was
$3,040,000, compared with $3,042,000 for 2004. R&D expense shifted
from pre-clinical activities to clinical trials. General and
Administrative expense for the full year 2005 was $3,615,000, or a 15%
decrease, compared with $4,262,000 incurred during 2004. The decrease
was due principally to a reduction in legal expense.

    Annual Shareholders Meeting

    The Company's Annual Meeting of Shareholders is scheduled to be
held on May 25th at 10 a.m. EDT at the Sheraton-Needham Hotel in
Needham, Massachusetts.
