Junshi Bio intends to introduce IL-2 series of products for US$88 million.

On September 30, Regency Bio announced that it intends to enter into a licensing agreement with Anwita Biosciences, which will grant Regency Bio the sole use of the Anti-HSA-IL-2N alpha series in the licensed area.

Under the agreement, Anwita will grant Regeneron exclusive license to use the Anti-HSA-IL2N alpha products and related ANWITA technologies and intellectual property rights agreed upon in the License Agreement alone in the licensed area, or to use them in combination with Regeneron's proprietary products, including IL-2N alpha proteins, Anti-HSA-IL-2N alpha fusion proteins and derivatives, and to develop and commercialize licensed products within the licensed area.

-2 (IL-2) is a globulin that plays an important role in maintaining the normal functioning of T lymphocytes and natural killer (NK) cells.
IL-2 is mainly produced by activated T-cells, which promote the proliferation and differentiation of T-cells, maintain T-cell activity, stimulate the production, proliferation and activation of NK cells, and induce the production of cytotoxic T lymphocytes (CTL) and induce and activate lymphocyte-activated killer cells (LAK) and tumor-immersed lymphocytes.
