Vion Pharmaceuticals Reports 2007 Third Quarter and Nine-Month Results

NEW HAVEN, Conn., Nov. 7 /PRNewswire-FirstCall/ -- VION PHARMACEUTICALS, INC. today announced results for the three-month and nine-month periods ended September 30, 2007.

The Company reported a net loss of $9.0 million, or $0.13 per share, for the three-month period ended September 30, 2007, compared to a net loss of $6.3 million, or $0.10 per share, for the same period in 2006. Weighted- average common shares outstanding for the three months ended September 30, 2007 and 2006 were 67.7 million and 66.2 million, respectively.

For the nine-month period ended September 30, 2007, the net loss was $25.8 million, or $0.39 per share, compared to a net loss of $19.2 million, or $0.29 per share, for the same period in 2006. Weighted-average common shares outstanding for the nine months ended September 30, 2007 and 2006 were 66.8 million and 66.2 million, respectively.

Total operating expenses were $8.6 million and $6.8 million for the three months ended September 30, 2007 and 2006, respectively, and $25.1 million and $20.8 million for the nine months ended September 30, 2007 and 2006, respectively.

In the quarter, the increase in operating expenses was due to higher total research and development expenses resulting from: (i) late-stage clinical development of Cloretazine(R) (VNP40101M), including additional personnel, drug production costs and other costs in support of a potential registration filing and (ii) stock-based compensation expense. In addition, marketing, general and administrative expenses were higher than the prior year quarter, primarily due to increased medical advisory board meetings and stock-based compensation expense.

In the nine-month period, the increase in operating expenses was due to higher total research and development expenses resulting from: (i) late-stage clinical development of Cloretazine(R) (VNP40101M), including additional personnel, drug production costs and other costs in support of a potential registration filing; (ii) stock-based compensation expense; and (iii) a gift to support research projects at a Yale University laboratory, partially offset by lower spending on preclinical drug production. In addition, marketing, general and administrative expenses were higher than the prior year period, primarily due to increased stock-based compensation expense, medical advisory board meetings and patent fees.

The Company reported $1.2 million and $3.4 million of stock-based compensation expense in the three-month and nine-month periods ended September 30, 2007, respectively, as compared to $413,000 and $1.4 million for the comparable 2006 periods.

The Company reported $3.7 million in interest expense for the nine months ended September 30, 2007 related to its private placement in February 2007 of convertible debt and warrants. There was no interest expense in 2006. Interest income increased from $1.6 million for the nine-month period ended September 30, 2006 to $2.6 million for the comparable 2007 period based on higher invested balances and higher interest rates in 2007.

The Company reported ending the quarter with $68.0 million in cash and cash equivalents. Based on its current operating plan, the Company reported that it had funds to operate the Company into the third quarter of 2009 excluding any expenses for commercialization of Cloretazine(R) (VNP40101M) in the United States. If the Company does commercialize Cloretazine(R) (VNP40101M) in the United States on its own, it would have to raise additional capital.

In August, the Company announced that it had completed the initial target accrual of 85 patients for its pivotal Phase II trial of Cloretazine(R) (VNP40101M) as a single agent in elderly de novo poor-risk acute myelogenous leukemia (AML). Recent FDA/ICH guidance recommends that an electrocardiograph evaluation (QT/QTc) study be included in the clinical development of all new drugs. Therefore, the trial continues to accrue patients at a few sites in the United States in a cardiac sub-study.

Alan Kessman, Chief Executive Officer, commented, “We will be presenting preliminary information from our pivotal Phase II trial of Cloretazine(R) (VNP40101M) as a single agent in elderly de novo poor-risk AML at the American Society of Hematology Meeting in December.” He concluded, “Our objective remains to file a New Drug Application (NDA) for Cloretazine(R) (VNP40101M) with the FDA in 2008 based on this trial. We are already working on preparing the appropriate documentation for the NDA.”

With regard to the pivotal Phase III trial in relapsed AML of Cloretazine(R) (VNP40101M) in combination with cytarabine which is on clinical hold, the Company announced that discussions with the data safety monitoring board (DSMB) related to the findings of a medical and safety review of the trial had been completed. The next step of the process is to discuss the conclusions with the regulatory authorities. There can be no assurance that these discussions will result in a continuation of the Phase III trial or what the timing of any such continuation might be.

Cloretazine(R) (VNP40101M), a unique alkylating agent, is being evaluated in a Phase II pivotal trial as a single agent in elderly patients with previously untreated de novo poor-risk acute myelogenous leukemia. Clinical trials of Cloretazine(R) (VNP40101M) as a single agent in small cell lung cancer, with temozolomide in brain tumors, and with stem cell transplant in advanced hematologic malignancies, are also being conducted.
