AVEO Reports First Quarter 2010 Financial Results

Significant Progress in Development of Lead Product Candidate Tivozanib; 2010 Financial Guidance Provided

CAMBRIDGE, Mass., Apr 29, 2010 (BUSINESS WIRE) --AVEO Pharmaceuticals, Inc. (NASDAQ: AVEO), a biopharmaceutical company focused on discovering, developing and commercializing cancer therapeutics, today announced financial results for the quarter ended March 31, 2010, provided an update on progress towards achievement of 2010 goals as well as 2010 financial guidance.

"We believe that we have made important progress with our lead product candidate tivozanib this quarter, including conducting an updated analysis of new data from our successful Phase 2 clinical trial in patients with renal cell carcinoma (RCC) which was presented at the 2010 Genitourinary Cancers Symposium in March of this year. The data from this trial showed a median progression-free survival of 14.8 months in patients with clear cell RCC who had undergone nephrectomy. The same patient population is currently being studied in TIVO-1, our global Phase 3 clinical trial of tivozanib in advanced RCC evaluating the efficacy of tivozanib compared to sorafenib," stated Tuan Ha-Ngoc, president and chief executive officer of AVEO. "In addition, we initiated patient enrollment at multiple sites around the world in TIVO-1, which is the first ever Phase 3 study in RCC designed to evaluate superiority in a head-to-head comparison against a widely prescribed anti-angiogenesis therapy in first-line RCC." The trial began enrolling patients in February 2010 and AVEO expects to enroll 500 patients at more than 90 sites in 16 countries.

Financial Highlights

Net loss for the quarter ended March 31, 2010 was $14.4 million, or $2.27 per common share, compared with $9.4 million, or $5.92 per common share, for the quarter ended March 31, 2009.

Total revenues for the quarter ended March 31, 2010 were $10.9 million compared with $3.7 million for the first quarter of 2009. Revenue during the first quarter of 2010 primarily reflected license fees, research and development funding and milestones earned under the company's strategic partnerships with Biogen Idec, Merck (formerly Schering-Plough), and OSI Pharmaceuticals. Included in revenue for the first quarter is a $5 million development milestone from Biogen Idec related to the AV-203 collaboration, AVEO's ErbB3 inhibitor antibody.

Research and development expenses for the quarter ended March 31, 2010 totaled $22.6 million compared with $9.7 million for the same period of 2009. The expense for the first quarter includes a $10 million payment to Kyowa Hakko Kirin in connection with the TIVO-1 study.

General and administrative expense was $2.8 million for the first quarter of 2010 compared with $2.6 million for the first quarter of 2009.

As of March 31, 2010, AVEO had cash, cash equivalents and marketable securities of $96.1 million compared with $51.3 million on December 31, 2009.

On March 17, 2010, the company completed its initial public offering of 9 million shares of common stock. On March 31, 2010, the underwriters for the initial public offering exercised their option to purchase an additional 968,000 shares of common stock to cover over-allotments. The closing of the sale of the additional shares occurred on April 6, 2010 and, therefore, are not included in the first quarter 2010 financial results. As a result of these two transactions, AVEO received net proceeds of approximately $80 million.

Approximately 29.9 million shares of common stock were outstanding at March 31, 2010.

About Tivozanib

Tivozanib, an investigational new drug, is a highly potent and selective inhibitor of VEGF receptors 1, 2 and 3, exhibiting picomolar inhibitory activity against all three receptors. Due to its potency and specificity, AVEO believes tivozanib may enable optimal inhibition of the VEGF pathway, while minimizing side effects associated with off-target activity. Such a profile may enable tivozanib to be more readily combined with standard chemotherapy as well as other targeted therapies, potentially increasing the breadth of its clinical utility.

Following the successful completion of Phase 1 and Phase 2 clinical trials, AVEO has launched a comprehensive clinical development program in support of tivozanib. In addition to the TIVO-1 trial, AVEO is currently conducting multiple Phase 1b clinical trials of tivozanib in various combinations and dosing regimens in RCC and additional solid tumor indications, including breast cancer and colorectal cancer.

About AVEO

AVEO Pharmaceuticals (NASDAQ: AVEO) integrates a proprietary cancer biology platform with drug development and commercial expertise in its efforts to discover and develop targeted cancer therapeutics. The company's lead product, tivozanib, is an oral, triple VEGF receptor inhibitor with potential for a best-in-class profile. Tivozanib is currently being investigated in a global, randomized Phase 3 clinical trial called TIVO-1 comparing tivozanib to sorafenib in advanced kidney cancer, as well as additional clinical studies in other solid tumor types. AVEO's proprietary, integrated cancer biology platform offers the company a unique advantage in oncology drug development that both increases the probability of clinical success and provides a discovery engine for high-value targets.
