Penpulimab 是一种 IgG1 抗PD-1单克隆抗体，具有抗肿瘤活性。
| 生物活性 | Penpulimab is anIgG1backbone anti-PD-1monoclonal antibody with antitumor activities[1]. |
体外研究
(In Vitro) | Penpulimab demonstrates better stability and a lower level of host-cell protein residue compared with IgG4 backbone anti-PD-1 antibodies[1].
Penpulimab does not mediate complement-dependent cytotoxicity (CDC) or antibody-dependent cell-mediated cytotoxicity (ADCC) and induces no remarkable IL-6 and IL-8 release by activated macrophages[1].
Penpulimab exhibits slower binding off-rate for human PD-1 than Nivolumab (HY-P9903) and Pembrolizumab (HY-P9902)[1].
Penpulimab potentiates T cell activation via PD-1/PD-L1 blockade[1].

体内研究
(In Vivo) | Penpulimab (5 mg/kg; i.p.; twice a week, 3weeks) inhibits tumor growth in mice[2].
| Animal Model: | MC38-hPD-L1 tumor-bearing B-hPD-1 humanized mouse model[2] | | Dosage: | 5 mg/kg | | Administration: | IP, twice a week, 3weeks | | Result: | Showed moderate inhibition of tumor growth (tumor volume: 58.4% of control group). Treatment combined with anlotinib (1 mg/kg, every day, p.o) significantly decreased tumor volume to 36.5% of control group. |
