Customer Review

Based on 1 Customer Validation

Anzurstobart (CC-95251; BMS-986351) is a CD47/SIRPα inhibitor with human SIRPα K_d of 0.0541 nM and human SIRPα IC₅₀ of 100 nM. Anzurstobart binds SIRPα at a CD47-overlapping site, blocks CD47-SIRPα interactions, inhibits CD47-SIRPα axis signaling, and binds across 6 prevalent human SIRPα haplotypes. Anzurstobart binds SIRPγ and inhibits CD47-SIRPγ interactions. Anzurstobart can be used for the research of non-Hodgkin's lymphoma, colorectal cancer, squamous cell carcinoma of the head and neck, diffuse large B-cell lymphoma, and advanced solid and hematologic malignancies.

For research use only. We do not sell to patients.

In Vitro

Anzurstobart (CC-95251) potently blocks CD47-SIRPα binding in a dose-dependent manner, with near-complete inhibition at 100 nM^[1].
Anzurstobart (50 nM; 180 seconds) demonstrates strong binding coverage across the six most prevalent human SIRPα haplotypes^[1].
Anzurstobart (20 nmol/L; 10 minutes preincubation, 3-hour coculture) alone dose-dependently increases macrophage-mediated phagocytosis of GP2d, GP5d, and SW480 colorectal cancer cells^[1].
Anzurstobart (20 nmol/L; 10 minutes preincubation, 3-hour coculture) in combination with Rituximab (HY-P9913) dose-dependently enhances macrophage-mediated phagocytosis of OCI-Ly3, RIVA, Pfeiffer, and Karpas 422 DLBCL cells, while Anzurstobart alone has limited phagocytic activity^[1].

In Vivo

Anzurstobart (CC-95251) (10-100 mg/kg; i.v.; single dose, repeat dose) results in dose-dependent peak serum concentrations, a half-life of 163-227 hours, and no hematologic cell depletion over 28 days in Macaca fascicularis^[1].
Anzurstobart (10-100 mg/kg; i.v.) is well-tolerated in healthy cynomolgus monkeys with no hematologic depletion observed^[2].

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
