Pro-Pharmaceuticals Reports First Quarter 2009 Financial Results

Newton, MA – May 15, 2009 – Pro-Pharmaceuticals, Inc. (OTCBB: PRWP), a developer of carbohydrate-based targeted therapeutic compounds to treat cancer and fibrosis, today reported its financial results for the first quarter of fiscal 2009. These results are included in the Company’s Quarterly Report on Form 10-Q for the three-month period ended March 31, 2009, which has been filed with the SEC.

For the three months ended March 31, 2009, the Company reported a net loss of $2,859,000, or ($0.06) per share, compared with a net loss of $2,069,000 or ($0.05) per share for the same period in 2008.

During the three months ended March 31, 2009, the Company closed a Series B-1 Redeemable Convertible Preferred Stock round of financing resulting in approximately $1,500,000 of net proceeds. At March 31, 2009, the Company had approximately $861,000 of cash and cash equivalents to fund future operations. On May 13, 2009, the Company completed a closing for gross proceeds of $900,000 on its offering of Series B-2 Redeemable Convertible Preferred Stock (“Series B-2”) for a total of 450,000 shares of Series B-2 and warrants to purchase shares of common stock. This transaction brings the total raised to $2.7 million of the $6 million commitment from the 10X Fund.

Research and development expense for the first quarter of 2009 was $153,000, compared with $422,000 for the same period in 2008. The decrease was due primarily to overall lower activity in clinical and pre-clinical programs as a result of cost containment measures. The Company expects to initiate its Phase lll trial as soon as it raises additional funds.

General and Administrative expense was $1,581,000, compared with $990,000 for the same period in 2008. The increase was due primarily to a one-time charge related to an employee separation agreement.

“We have a clear pathway to submit a new drug application (NDA) to the Food and Drug Administration (FDA) to commercialize DAVANAT®,” said Theodore Zucconi, Ph.D., Chief Executive Officer, Pro-Pharmaceuticals. “Results of our pre-clinical studies and clinical trials show significant clinical and economic benefits to cancer patients by adding DAVANAT® to their chemotherapy treatment. Results include extended patient survival, improved quality of life, reduced side effects, and lower costs associated with patient care. For example, no mucositis serious adverse events (SAEs), grades 3, 4 or 5, were found in approximately 100 cancer patients that were treated with DAVANAT® and 5-FU. Typically, up to 40% of patients treated with 5-FU get mucositis. SAEs of grade levels 3, 4, or 5 can result in life threatening events, in-patient hospitalization, persistent or significant disability, and/or death. 5-FU is one of the most widely used chemotherapy drugs in the world and is used to treat various types of cancers, including colorectal, breast and gastrointestinal.

“We plan to initiate a Phase lll trial for approximately 300 late-stage colorectal cancer patients this year. As part of this trial, we expect to conduct a pharmacokinetic (PK) analysis of approximately 60 patients, which may allow the Company to file an NDA for DAVANAT® as an adjuvant when administered with 5-FU. Adjuvants are pharmacological or immunological agents that modify the effect of drugs. We also are actively engaged in discussions with potential partners, that include large pharmaceutical companies, distributors for DAVANAT® in the Mid-East and Korea and have initiated discussions with potential partners in South America,” said Zucconi.


DAVANAT®, the Company's lead product candidate, is a carbohydrate polymer composed of mannose and galactose. DAVANAT®'s mechanism of action is based on interacting with lectins on the cell surface. DAVANAT® targets specific lectin receptors (galectins) that are over-expressed on cancer cells. Current research indicates that galectins affect cell development and play important roles in cancer, including tumor cell survival, angiogenesis and tumor metastasis. DAVANAT® is a drug that is not yet approved for commercial use by the FDA.
