Lion Biotechnologies Obtains Exclusive License From NIH for Next-Generation TIL Technology

LOS ANGELES, Feb. 11, 2015 (GLOBE NEWSWIRE) -- Lion Biotechnologies, Inc. (OTCQB:LBIO), a biotechnology company that is developing novel cancer immunotherapies based on tumor-infiltrating lymphocytes (TIL), today announced that it has obtained an exclusive, worldwide license from the National Institutes of Health (NIH) to intellectual property related for a next-generation TIL technology for the treatment of metastatic melanoma. This announcement follows a separate exclusive licensing agreement with the NIH for other TIL technologies, which was announced earlier this week.

The novel technology supports more potent and efficient TIL production from melanoma tumors by selecting for T-cell populations that express various inhibitory receptors, including 4-1BB (also known as CD137), PD-1, TIM-3 and/or LAG-3. TIL that express these proteins are associated higher tumor reactivity than other TIL populations, so fewer of the enriched cells are needed to be therapeutically effective.

In addition, the technology has potential to substantially reduce the time and cost of manufacturing. The licensed technology is currently being tested at the National Cancer Institute in a Phase 2 clinical trial in metastatic melanoma.

"This exclusive license from the NIH represents an expansion of our intellectual property portfolio, as well as an important step in the development of next-generation TIL therapies," said Elma Hawkins, PhD, Lion's president and CEO. "The licensed technology is expected to meaningfully enhance the quality and efficiency of TIL production for melanoma treatment. We look forward to continuing to work with the NIH to develop and commercialize new treatments based on this innovative platform."
