(AXO.TO, ALXFF.OTC) announced its financial results for the fourth quarter and year ended December 31, 2002. All dollars reported are Canadian. The Company recorded a net loss of $0.8 million, or $0.02 per share, for the three months ended December 31, 2002 compared to a net loss of $10.1 million, or $0.31 per share, for the same period in 2001. For the year ended December 31, 2002, the Company recorded a net loss of $8.5 million, or $0.20 per share, compared to a net loss of $33.8 million, or $1.21 per share, for the same period in 2001. The decreased net loss for each of the 2002 periods primarily reflects the April 17, 2002 license to United Therapeutics Corporation of the Company's OvaRex(R) and certain other MAb products for North America, Japan, and other countries, United's assumption of ongoing development responsibilities and associated expenses of OvaRex(R) MAb in the licensed territory, United's hiring of certain former personnel of the Company and a resulting significant decrease in the Company's research and development and supporting general administrative expenses in the third and fourth quarters of 2002. At December 31, 2002, the Company's cash, cash equivalents and short-term investments totaled $3.6 million as compared to $9.1 million at December 31, 2001. The Company believes that its available cash and cash equivalents and interest earned thereon should be sufficient to finance its operations and capital needs into the third quarter of 2003. The Company is currently pursuing corporate alliances and financing options in order to raise the cash required to continue to fund its operations. AltaRex Corp. is focused on the research, development and commercialization of foreign antibodies that modulate the immune system for the treatment of certain cancers and other diseases where there exists an unmet medical need.
