Exhibit 99.1
ADVENTRX Announces Positive Efficacy and Safety Results from CoFactor Phase II Clinical Trial
Increased Clinical Benefit with Low Toxicity Reported in Patients
Results presented at 2006 Gastrointestinal Cancers Symposium in San Francisco
SAN
DIEGO January 30, 2006 ADVENTRX Pharmaceuticals, Inc. (Amex: ANX) today announced that it
presented positive efficacy and safety data from its Phase II multi-center CoFactorä clinical
trial at the 2006 Gastrointestinal Cancers Symposium in San Francisco. Objective results from an
independent radiology organization concluded there was an overall clinical benefit of 85%. The
Company also reported longer than expected time to tumor progression (TTP), with no drug-related
grade 3 or grade 4 gastrointestinal or hematological toxicities. These and other findings from a
blinded, expert assessment of radiographical tumor stabilization and regression data were included
in the presentation. The Company contracted the independent radiology organization to ensure the
objectivity and integrity of the Phase II clinical trial response data.
We are very encouraged by the findings of the independent reviewers. The high level of activity
and low toxicity of CoFactor plus 5-fluorouracil (5-FU) suggests that this combination may prove
useful as an initial treatment for metastatic colorectal cancer, especially among patients who
would benefit from minimizing toxicity, said Evan M. Levine, president and CEO for ADVENTRX.
These results give us added confidence as we proceed to our Phase III pivotal study.
Objective, third-party-confirmed tumor response results from Phase II CoFactor plus 5-FU trial
| Third-party radiological assessments established a clinical benefit of 85% following treatment with CoFactor and 5-FU, a higher outcome than the Company reported previously. The Company previously reported a clinical benefit of 65% as assessed by the clinical site investigators. Clinical benefit is defined as the percentage of patients on study drug whose tumors shrunk or stabilized. |
| The primary endpoint for the study, objective response, as determined by blinded third-party radiology assessment, exceeded the 25% target originally established for the trial. The reviewers determined that 35% of patients achieved an objective response and 9% of patients exhibited a minor response with CoFactor and 5-FU. Objective response is defined as those patients having complete or partial tumor responses and minor response is defined as a tumor reduction of less than 50% of total tumor size. A complete response is a complete disappearance of the tumor and a partial response is at least a 50% reduction in total tumor size. These measurements were confirmed by a repeat MRI or CT scan performed no less than four weeks after the criteria for response are first met, as defined by World Health Organization (WHO) criteria. |
| Forty-one percent of patients exhibited stable disease and 15% exhibited progressive disease. Stable disease is no evidence of response (CR, PR, or MR) or progression; and progressive disease is at least a 25% increase in tumor size at the end of the treatment cycle, as measured by CT or MRI scans. |
The audit of our primary efficacy endpoint by a team of independent experts, operating under a
pre-defined and quality-assured procedure to ensure the integrity of the data, has corroborated the
findings of the clinical investigators, suggesting that CoFactor with 5-FU may be a highly
effective therapy for patients with metastatic colorectal cancer, commented James Merritt, MD,
chief medical advisor for ADVENTRX. By historical comparison, the published response rates for IV
bolus leucovorin plus 5-FU administered in a multi-institutional setting have averaged only about
10-20%, compared to 35% which was observed in this CoFactor Phase II study.
Time to tumor progression and safety results from the Phase II CoFactor plus 5-FU trial
| Time to tumor progression (TTP), a secondary endpoint of the study, was reported to have reached 163 days, or greater than 5.4 months, surpassing the Companys expectations. TTP is defined as the time from the start of treatment until objective tumor progression. The determination for TTP is given as a median value based on Kaplan-Meier estimates. |
| Median survival, another secondary endpoint of the study, could not be reported at this time since more than 50% of the patients on the study are still alive. |
Importantly, the response rate and time to tumor progression numbers have surpassed previous
published values from multiple institutional studies using leucovorin and 5-FU, including the
registration trials for irinotecan and capecitabine, for which the CoFactor Phase II time to tumor
progression was approximately 25% longer, added Dr. Merritt.
CoFactor plus 5-FU regimen well tolerated
| No grade 3 or 4 drug-related hematological toxicities were recorded for patients during the trial and there were no grade 3 or 4 gastrointestinal toxicity events related to the CoFactor/5-FU treatment regimen, demonstrating that the treatment was well tolerated. Toxicity grades were determined in accordance with the National Cancer Institutes Common Terminology Criteria for Adverse Events grading system. |
CoFactor plus 5-FU helped stabilize the overwhelming majority of these patients and did so
with a minimum of serious hematological or gastrointestinal toxicity, commented Joan M. Robbins,
Ph.D. chief scientific officer and executive vice president for ADVENTRX. These findings further
support the development of CoFactor in chemotherapy regimens that utilize 5-FU. While we have not
reached a median survival value, we currently plan to announce that value and related data after
they become determinable.
The abstract 5,10-methylenetetrahydrofolic acid with 5-fluorouracil as first line treatment in
metastatic colorectal cancer: a phase II study was presented by Tony Reid, M.D., Ph.D., Associate
Professor, Director Gastrointestinal Malignancy Program, Department of Hematology/Oncology at the
University of California San Diego (UCSD) and principal investigator for the Phase II CoFactor
trial.
About the Phase II CoFactor trial
The Phase II clinical trial is an open label, single arm Simon two-stage study design to assess the safety and efficacy of CoFactor plus 5-FU as a first line treatment of metastatic colorectal cancer. Patients enrolled in the trial had performance status ECOG 0-2 and measurable metastatic colorectal cancer, with or without prior adjuvant chemotherapy including 5-FU/leucovorin but no prior chemotherapy for metastatic disease. Patients may receive more than two cycles each consisting of CoFactor 60 mg/m2 and 5-FU 450 mg/m2 (weekly IV bolus) for six consecutive weeks, followed by a 14 day rest period, which is defined as a cycle. The trial is being conducted in the U.S. and Europe under a U.S. investigational new drug application.

About CoFactor
CoFactor (ANX-510) is a folate-based biomodulator drug being developed to enhance the activity and reduce associated toxicity of the widely used cancer chemotherapeutic 5-fluorouracil (5-FU). In comparison to leucovorin, CoFactor creates more stable binding of the active form of 5-FU to the target enzyme, thymidylate synthase (TS). CoFactor bypasses the chemical pathway required by leucovorin to deliver the active form of folate, allowing 5-FU to work more effectively. This improves 5-FU performance and lowers toxicity. A Phase IIb randomized controlled clinical trial is ongoing to evaluate CoFactor with 5-FU as a first line treatment of metastatic colorectal cancer. The Company has received clearance under a special protocol assessment from the US Food and Drug Administration (FDA) to begin a CoFactor Phase III pivotal clinical trial for metastatic colorectal cancer, which is currently planned to begin patient dosing in Q1 2006.
