SHANGHAI, Dec. 25, 2017 -- (Healthcare Sales & Marketing Network) -- HyLeukin is an immuno-oncology agent comprised of an optimally engineered Interleukin-7 (IL-7) molecule based on Genexine's proprietary long-acting platform technology. Genexine will establish a joint development committee with I-Mab to pursue global commercialization and new drug development of multi-target antibody-based candidates in immuno-oncology areas. Under the terms of the agreement, I-Mab will provide an upfront payment in exchange for an exclusive license for development and commercialization rights of HyLeukin in greater China in the field of oncology. In addition, there is potential for various milestone payments and tiered, low single digit royalty payments to Genexine, contingent on regulatory approvals, and accumulated net sales. Further financial details are not disclosed.

"We are very excited to have brought our partnership with Genexine to a new level. This is a highlight of many on-going projects we have been collaborating with", said Jingwu Zang, founder and CEO of I-Mab Biopharma. I-Mab plans to develop this clinical stage asset in China for cancer patients whose immune cells and functions are severely compromised. "We hope to develop this investigational medicine of the first-in-class potential in parallel with its global development. So, if proven safe and efficacious, patients in China can benefit from such a treatment in line with or even ahead of a global timeline", commented by Jingwu Zang.

About HyLeukin

HyLeukin is an immuno-oncology agent designed to reconstitute and enhance anti-tumoral Tcell immunity. It consists of an optimally engineered Interleukin-7 (IL-7) molecule biologically fused with the Genexine's proprietary long-acting platform technology, hybrid Fc (hyFc). HyLeukin is under co-development with Neo Immune Tech (NIT), a US-based spin-off company of Genexine. Genexine recently completed Phase I trial in Korea and based on the current results, HyLeukin demonstrated it was safe and well tolerated in healthy volunteers. Genexine plans to target patients with solid tumors in Korea, and NIT is preparing various US clinical trials including Glioblastoma in 2018. IL-7 is known to be a critical factor for T cell which does not only increase the number of T cells but also enhances T cell functionality. Furthermore, according to clinical results revealed in the literature, IL-7 is expected to have strong synergistic effects with other immuno-oncology drugs such as check point inhibitors.
