THRESHOLD PHARMACEUTICALS REPORTS FOURTH QUARTER AND YEAR END 2005

FINANCIAL RESULTS AND PROVIDES 2006 GUIDANCE

— Company to Host Conference Call at 4:30 p.m. ET Today —

REDWOOD CITY, CA – March 1, 2006 – Threshold Pharmaceuticals, Inc. (Nasdaq: THLD), today reported financial results for the fourth quarter and year ended December 31, 2005.

The net loss for 2005 was $44.4 million compared to a net loss of $23.6 million in 2004. Total research and development expenses for 2005 increased to $36.0 million from $16.3 million in 2004, as clinical trials for the Company’s product candidates progressed, and staffing increased to support clinical development activities. General and administrative expenses were $11.2 million for 2005 versus $7.6 million in 2004. This increase was primarily due to additional expenses related to being a public company and increased patent expenses. Threshold recognized revenue of $0.7 million for the year ended December 31, 2005 related to a development agreement. Non-cash stock compensation expense was $9.4 million for 2005 versus $6.0 million for 2004.

The net loss for the fourth quarter of 2005 was $15.2 million compared to $7.9 million for the fourth quarter of 2004. Research and development expenses were $13.8 million for the fourth quarter of 2005 versus $5.5 million for the fourth quarter of 2004. The increase in research and development expenses primarily reflects increased costs of advancing the Company’s product pipeline, including Phase 2 and Phase 3 multi-center clinical trials of TH-070 for the treatment of benign prostatic hyperplasia (BPH), an ongoing Phase 3 study of glufosfamide for the second-line treatment of patients with pancreatic cancer and a Phase 2 study of glufosfamide in combination with gemcitabine for first-line treatment of pancreatic cancer. General and administrative expenses were $2.7 million for the fourth quarter of 2005 versus $2.5 million for the fourth quarter of 2004. The Company recognized revenue of $0.4 million in the fourth quarter of 2005. Non-cash stock compensation expense was $3.8 million for the fourth quarter of 2005 versus $2.2 million for the fourth quarter of 2004.

As of December 31, 2005, Threshold had $99.7 million in cash and marketable securities, which included net proceeds from an initial public offering and a follow-on public offering completed in February and October 2005, respectively.

“We achieved all of our key corporate and clinical milestones for 2005 and are looking forward to achieving significant milestones in 2006,” said Barry Selick, Threshold’s chief executive officer. “Over the past year, we initiated two placebo-controlled, multi-center trials of TH-070 for BPH: a Phase 2 trial in the United States and a Phase 3 study in Europe. We also reported encouraging Phase 1 results for glufosfamide plus gemcitabine in the first-line treatment of advanced solid tumors that enabled us to move that combination regimen into Phase 2 trials in advanced pancreatic cancer patients. In addition, we raised approximately $100 million in net proceeds through our initial public offering and follow-on public offering, both of which were completed last year.”
