May 25, 2020, Akesobio (9926.HK) announced Center for Drug Evaluation(CDE), National Medical Products Administration (NMPA) has accepted the application for anti PD-1 monoclonal antibody drug（安尼可） penpulimab (AK105) for the treatment of recurrent or refractive classic Hodgkin's Lymphoma after at least second-line chemotherapy. Such drug was developed and commercialized by Akesobio (9926.HK) and China Biopharmaceutical Co. Ltd. (1177.HK).
Professor Zhu Jun, CO principal investigator of the lead unit Beijing Cancer Hospital said, " Through bioengineering technology, penpulimab completely eliminate the binding activity of Fc receptors and avoid the ADCC effect. At the same time, compared with other drugs （已上市）on the same target, it has a slower rate of antigen binding and dissociation, which makes the biological effect stronger and improves its anti-tumor activity. I am full of expectations for such a differentiated PD-1 mono-resistance？ product developed by Akesobio.” Co-lead researcher Professor Song Yuqin, Director of lymphoma Department at Peking University Cancer Hospital, said, "In clinical trial, penpulimab was observed with gratifying therapeutic data and good safety, and as a clinician, it is hoped that penpulimab will become a high-quality, clinically proven innovative PD-1 monoclonal antibody that will bring good news to patients."
The Chairwoman and CEO of Akesobio Dr. Michelle Yu said, "Since the establishment of joint venture with Chia-Tai Tianqing (“CTTQ"), the principal subsidiary of Sino Biopharm to research and commercialize Penpulimab together, Penpulimab has continuously reached new milestone. We sincerely hope that, if approved, the monoclonal antibody drug Penpulimab will provide a meaningful and affordable treatment for Hodgkin's lymphoma patients."
About classical Hodgkin’s lymphoma
Classical Hodgkin lymphoma (cHL) is a B cell lymphoma, and is the most common malignancy among young people. The age incidence rate curve is single peak in China, and the peak incidence rate is about 40 years old. cHL is one of the few curable tumors. Chemotherapy (such as ABVD) plus radiotherapy is usually used. More than 80% of the patients can reach a 5-year survival rate. Although the first-line chemotherapy has a high clinical cure rate, a considerable number of patients are not sensitive to chemotherapy, about 5% to 10% of patients have no response to the initial treatment, 10% to 30% of patients have progress or relapse after the first-line treatment reaches complete remission, the treatment of patients after relapse is still a big problem.

Penpulimab (AK105, PD-1 antibody) is a late-stage, differentiated and potentially best-in-class humanized monoclonal antibody against PD-1. Penplulimab was engineered to eliminate FC receptor binding activity, particularly with respect to Fc γ R and effectively eliminates undesirable fragment crystallizable (Fc)-receptor-mediated effects, such elimination has been shown to improve the anti-tumor activity of PD-1 antibodies and slower antigen binding off-rate as compared with the currently marketed PD-1 antibodies. Akeso have forged partnership with Chia Tai Tianqing, the principal subsidiary of Sino Biopharm for the joint development and commercialization of Penpulimab, Penpulimab is the only PD-1 antibody that Sino Biopharm can use to develop PD-1-based monotherapy or combination therapy.
