Pelgifatamab
Based on 1 Customer Validation
Peligifatamab is a PSMA-targeted α-radioimmunoconjugate with an EC50 of 1.2 nM against human targets. Peligifatamab induces DNA damage, DNA double-strand breaks, cell cycle arrest and apoptosis (Apoptosis) in PSMA-positive prostate cancer cells. Peligifatamab reduces cell viability in a manner dependent on cellular PSMA expression levels. Peligifatamab inhibits tumor growth and tumor-induced abnormal bone growth in prostate cancer bone metastasis models. Peligifatamab exhibits antitumor efficacy in subcutaneous prostate cancer models and xenograft models. Peligifatamab can be used for the research of metastatic castration-resistant prostate cancer.

Peligifatamab (100-500 kBq/kg; i.v.; single dose) exhibits potent antitumor efficacy in androgen-independent and castration-resistant subcutaneous prostate cancer xenografts, with a T/C ratio as low as 0.09 at a single dose of 500 kBq/kg in MDA-PCa-2b xenografts[1].
Peligifatamab (75-500 kBq/kg; 4×75 kBq/kg; 4×125 kBq/kg; 2×150 kBq/kg; 2×250 kBq/kg; i.v.; single dose; weekly; biweekly) induces potent antitumor efficacy in xenografts of prostate cancer, with a T/C ratio as low as 0.01 in ST1273 xenografts when a single dose of 500 kBq/kg is administered[1].
Peligifatamab (100-200 kBq/kg; i.v.; single dose) potently inhibits tumor growth and tumor-induced bone tissue changes in an intratibial prostate cancer bone metastasis model, with a single dose of 100 kBq/kg resulting in a T/C ratio of 0.03[1].
Peligifatamab (500 kBq/kg; total antibody 0.14-5 mg/kg; i.v.; single dose) maintains potent antitumor efficacy in the 22Rv1 xenograft model when the total antibody dose ranges from 0.14 to 1.5 mg/kg, whereas the efficacy decreases at a total antibody dose of 5 mg/kg[1].
