Tularik Reports 2004 First Quarter Financial Results
South San Francisco, Calif., April 22, 2004 – Tularik Inc. (Nasdaq: TLRK) today reported results for the first quarter ended March 31, 2004. Revenue for the quarter was $10.9 million, compared to 2003 first quarter revenue of $6.7 million. Net losses for the quarter were $23.8 million, or $0.36 per share, compared to a net loss of $24.2 million, or $0.44 per share, for the same period in 2003. At March 31, 2004, Tularik had $178.2 million in cash, cash equivalents and marketable securities, including $10.1 million from Tularik’s majority-owned subsidiary, Cumbre Inc.
On March 29, 2004, Amgen Inc. and Tularik jointly announced that they have signed a definitive merger agreement whereby Tularik will become a wholly-owned subsidiary of Amgen in a stock-for-stock transaction. Under the terms of the agreement, Amgen, in a tax-free transaction, will exchange Tularik common stock for Amgen common stock in a ratio that fixes Tularik’s value at $25 per share based on the average Amgen stock price during a set number of trading days prior to the close of the transaction. The value of the transaction as of the anticipated closing date is expected to be approximately $1.3 billion, net of estimated cash to be acquired and net of Amgen’s existing ownership of Tularik of approximately 21 percent. The transaction is expected to close in the second half of 2004.
Clinical Highlights:
| • | Tularik is conducting a pivotal trial with T67 for the first-line treatment of hepatocellular carcinoma (HCC), a primary liver cancer. T67 is an anti-cancer drug candidate with a novel chemical structure that binds to ß-tubulin, a known anti-cancer drug target. An interim analysis of data collected on the first 100 patients enrolled will be conducted this quarter by the Data Monitoring Committee. |
| • | Tularik’s second anti-cancer drug candidate, T607, is an analog of T67. Tularik is conducting Phase 2 studies with T607 for the treatment of esophageal cancer and gastric cancer. |
| • | Tularik is conducting a Phase 2 study of T487 in patients with psoriasis. T487 is an antagonist to CXCR3, a chemokine receptor implicated in autoimmune and inflammatory diseases. The Company expects to begin a Phase 2 study of T487 in patients with rheumatoid arthritis this quarter. |
| • | Tularik is conducting a Phase 2 study of T131 in patients with type 2 diabetes. T131 is a selective modulator of PPAR³ (peroxisome proliferator-activated receptor gamma), a protein involved in the body’s ability to respond to insulin. Preclinical data suggest T131 may have an improved safety profile compared to that of existing agents. |
| • | Tularik is currently enrolling volunteers in a Phase 1 study with T71 for obesity. T71 is an orally-active drug candidate that decreases food consumption and increases metabolic rate in preclinical studies. The single ascending dose study is complete and the multiple ascending dose Phase 1 study is scheduled to be completed by the fourth quarter of this year. |
Financial Results
Revenues for the first quarter of 2004 totaled $10.9 million, compared to revenues of $6.7 million for the same period in 2003. Collaborative research revenues comprised all of the first quarter 2004 revenues and were derived from research collaborations with Amgen Inc., Japan Tobacco Inc., Medarex, Inc. and Sankyo Company, Limited. Revenues for the first quarter of 2004 increased as compared to 2003 due to our collaboration with Amgen and the expansion of our collaboration with Sankyo. Additionally, we recorded $2.9 million in revenue related to the termination in May 2004 of the research portion of our metabolic disease collaboration with the pharmaceutical division of Japan Tobacco.
Total operating expenses for the three months ended March 31, 2004 increased to $34.7 million from $31.3 million for the same period in 2003. The increase in 2004 operating expenses was primarily due to increased costs associated with research and development headcount and overhead, and the progression of clinical programs.
Interest income decreased to $0.6 million for the first quarter of 2004 from $0.8 million for the first quarter last year. The decrease was due to lower yields on our investment portfolio.
Net loss for the first quarter of 2004 was $23.8 million, or $0.36 per share, compared to a net loss of $24.2 million, or $0.44 per share, for the same period in 2003.
