Pain Therapeutics, Inc. (Nasdaq: PTIE) announced today it has received approval from the Ministry of Health in Israel to begin human testing of a new treatment for metastatic melanoma, a deadly form of skin cancer.

Pain Therapeutics' initial Phase I study is designed to evaluate the pharmacokinetics of a proprietary radio-labeled monoclonal antibody in patients diagnosed with metastatic melanoma. The Company expects to initiate this first-in-human Phase I study in a limited number of patients in Q2 2007 across several major academic medical centers in Israel.

"It is common knowledge that patients with this type of cancer have limited treatment options," said Nadav Friedmann, Ph.D., MD, chief operating and medical officer of Pain Therapeutics. "We hope the evaluation of this agent in the clinic replicates the promising activity we saw in preclinical studies."

Pain Therapeutics continues to expect its net cash requirements for 2007 to be approximately $10 million, inclusive of program expenses related to metastatic melanoma. At December 31, 2006 the Company's cash, cash requirements and marketable securities were $204.4 million.

About Metastatic Melanoma

Melanoma is a deadly form of skin cancer. According to the American Cancer Society, melanoma accounts for approximately 5% of all skin cancers but causes about 75% of all skin cancer-related deaths. An estimated 60,000 people will be diagnosed and nearly 8,000 people will die from melanoma in 2007 in the U.S. alone. If diagnosed and surgically removed, early-stage melanoma is potentially curable. However, for patients with metastatic melanoma, the prognosis is poor, with limited available treatments and a median survival time of 8.5 months and a 5-year survival rate of 3%. There has been little change in these results in over 25 years. The incidence of melanoma has increased more rapidly than any other cancer during the past 10 years. The last drug to treat patients with melanoma was approved by the FDA 30 years ago.
