Recent Highlights

* Patient enrollment continued in both the AVN944 Phase I clinical trial for hematological patients and the AVN944 Phase II (a) clinical trial for pancreatic patients.
* Presentation of preliminary results from the AVN944 Phase I trial in adult Acute Myelogenous Leukemia (AML) patients that showed AVN944 is well tolerated in refractory AML patients, with drug exposure increasing at higher dose levels and patients experiencing reductions in blast cell counts. These data were presented at the American Society of Hematology (ASH) Annual Meeting.
* An additional ASH presentation showed the small molecule compound family in the Company’s Beta-catenin pathway inhibitor program has potent inhibitory effects on Wnt/Beta-catenin signaling in Multiple Myeloma (MM) cells. The Beta-catenin pathway is activated in the majority of MM cells, and is known to play a critical role in Myeloma cell survival. The Company previously demonstrated that this compound family potently inhibits colorectal cancer cell growth.
* The Company’s drug discovery collaboration with Novartis progressed to the next stage which triggered an undisclosed payment to Avalon for research support. In the current phase of this collaboration, the Company is characterizing compounds identified from the completed high-throughput screen.
* The Company identified hit compounds that affect the Hsp90 pathway under its collaboration with ChemDiv.
* Dr. Philip Frost, M.D., Ph.D., was appointed to the Company’s board of directors. Dr. Frost has extensive experience in drug discovery and development over a very successful career in industry and academia, including leading positions at Imclone, Wyeth, the University of Texas M.D. Anderson Cancer Center and the University of California, Irvine.

Company Expectations for 2008

The Company is advancing numerous programs in its strategy of building a pipeline of first-in-class drugs and is driving to attain the following goals in 2008.

* Complete AVN944 Phase II(a) clinical trial (Pancreatic)
* Initiate AVN944 Phase II(b) clinical trial (Pancreatic)
* Complete AVN944 Phase I clinical trial (Hematological)
* Name Beta-catenin development candidate and begin pre-IND enabling work
* Name Aurora/Centrosome novel target
* Partner AVN944 and/or the Beta-catenin program
* Sign additional discovery partnership

Financial Results

For all of 2007, net loss was $21.7 million, compared with $17.1 million in 2006. Lower revenues and higher costs in the 2007 periods resulted in the higher losses in 2007.
