TNOX Tanox (MM)

Quarterly Revenue Grows 66% Year Over Year HOUSTON, May 2 /PRNewswire-FirstCall/ -- Tanox, Inc. (NASDAQ:TNOX) today reported financial results for the first quarter ended March 31, 2006. Revenues for the first quarter of 2006 were $9.8 million compared to revenues of $5.9 million for the first quarter of 2005, and $23.0 million(1) for the fourth quarter of 2005. Net royalty revenue from sales of Xolair(R) (omalizumab) was $8.8 million for the first quarter of 2006, compared to Xolair royalty revenue of $5.9 million for first quarter of 2005, and $8.5 million for the fourth quarter of 2005. In addition to royalty revenue, Tanox recorded net profit-sharing revenue of $1.0 million for the first quarter of 2006. The profit-sharing revenue represented Tanox's share of Novartis Pharma AG's net profits from U.S. sales of Xolair in the fourth quarter of 2005. Profit-sharing payments are calculated and recorded one quarter in arrears. Tanox reported a net loss of $5.2 million, or $0.12 per share, for the first quarter of 2006, compared to a net loss of $20.5 million(2), or $0.46 per share, for the first quarter of 2005, and net income of $9.8 million, or $0.23 per share, for the fourth quarter of 2005. Results for the first quarter of 2006 reflect the company's Jan. 1, 2006 adoption of Statement of Financial Accounting Standards No. 123R. The impact of expensing employee stock options is reflected in the table below: Loss Per Share Before Stock Stock Reported Compensation Compensation Loss Expense Expense Per Share First Quarter 2006 ($0.10) ($0.02) ($0.12) (1) Fourth quarter 2005 revenue of $23.0 million included a one-time net milestone payment of $12.8 million based on Xolair achieving sales of more than $300 million for the first time. (2) The net loss for the first quarter of 2005 included a one-time $13.7 million expense for in-process research related to the company's acquisition of a tissue factor antagonist program from Sunol Molecular Corporation. "We continue to be pleased with the market performance of Xolair and the impact the collaboration with Genentech and Novartis is having on our business," said Danong Chen, president and chief executive officer of Tanox. "Increasing revenue from our Xolair collaboration is providing us with financial resources to invest in our drug development programs and advance our pipeline." Research and development costs for the first quarter of 2006 were $14.0 million, compared to $11.7 million for the first quarter of 2005, and $12.7 million for the fourth quarter of 2005. The increase in research and development costs for the first quarter of this year was attributed primarily to expenses associated with manufacturing activities in preparation for planned clinical trials, increased spending for preclinical programs and employee stock compensation expense. General and administrative expenses were $2.8 million for the first quarter of 2006, compared to $1.9 million for the first quarter of 2005, and $1.9 million for the fourth quarter of 2005. The increase in general and administrative costs for the first quarter of this year was due primarily to expenses related to business development activities and employee stock compensation expense. As of March 31, 2006, Tanox had $171.9 million in cash and investments, compared to $164.5 million at Dec. 31, 2005. The increase in cash is due primarily to the one-time net milestone payment of $12.8 million received in the first quarter of 2006. Recent and First Quarter Company Highlights * Earlier today, Tanox reported positive 48-week results of the Phase 2 clinical trial of TNX-355. The results showed that TNX-355, when given in combination with an optimized background regimen (OBR) of other antiretroviral therapies, produced a statistically significant greater reduction in viral load in HIV-infected patients than did placebo in combination with OBR. The 48-week results also showed that patients who received TNX-355 plus OBR experienced a statistically significant increase in CD4+ cells compared to patients who received placebo plus OBR. An end-of-Phase 2 meeting with the Food and Drug Administration (FDA) is scheduled to take place by the end of the second quarter of this year. * The company began Good Manufacturing Practice (GMP) production of TNX-355 clinical material at its San Diego facility. * Tanox continued to advance its drug-development pipeline in the first quarter, with ongoing patient enrollment in a Phase 1/2 clinical trial of TNX-832 (acute lung injury/acute respiratory distress syndrome), and preclinical studies for TNX-650 (inflammatory disease), TNX-833 (cancer) and TNX-234 (age-related macular degeneration). In addition, the company anticipates dosing patients in a Phase 1 clinical trial of TNX-650 in Hodgkin's lymphoma in the second quarter of 2006. Financial Outlook The company reaffirms its previous guidance and continues to anticipate net cash usage in 2006 of approximately $15 million.

This news release contains forward-looking statements based on current expectations that involve a number of risks and uncertainties. We typically identify forward-looking statements by using terms such as "may," "should," "could," "expect," "plan," "anticipate," "believe," "estimate," "predict," "potential" or similar words, although we express some forward-looking statements differently. You should be aware that actual events could differ materially from those suggested in the forward-looking statements due to a number of factors, including: the continued market acceptance of Xolair(R); the results of our collaborators, Genentech and Novartis, in growing sales of Xolair; our ability to successfully recruit participants for human clinical trials; failure to achieve positive results in human clinical trials; and the strength of our patent portfolio. The absence of safety concerns after 48 weeks of treatment with TNX-355 in 82 patients does not ensure that safety issues will not be identified in larger-scale clinical trials. The therapeutic potential of TNX-355 as a treatment for HIV-1-infected patients is subject to the risks inherent in drug development. The timing of future trials can depend on regulatory review. Success in early stage clinical trials does not ensure that later-stage or larger-scale clinical trials will be successful, and the results achieved in later stage trials may not be sufficient to meet applicable regulatory standards.
