Promiximab
Promiximab is a humanized anti-CD56 IgG1 monoclonal antibody with a Kd value of 0.78 pM against the human target. Promiximab specifically binds to CD56-positive small cell lung cancer (SCLC) cells, possesses antiproliferative activity, and induces tumor regression. Promiximab serves as the antibody component of the antibody-drug conjugates Promiximab-DUBA and Promiximab-MMAE. Promiximab can be used in studies related to small cell lung cancer.

In Vitro
Promiximab (0.02-1200 nM; 72 h) does not inhibit the viability of CD56-expressing small cell lung cancer (SCLC) cell lines NCI-H526, NCI-H524, NCI-H69, or human NK cells at concentrations up to 1200 nM[1].
Promiximab (1 μg/mL; 30 min) specifically binds to CD56-expressing small cell lung cancer (SCLC) cell lines NCI-H526, NCI-H524 and NCI-H69, but does not bind to CD56-negative SCLC cell lines NCI-H446 and NCI-H128[1].
Promiximab (1 μg/mL; 4 h) binds to both glycosylated and deglycosylated CD56 ECD, and cross-reacts with human CD56-expressing cells[1].
Promiximab (10 μg/mL; 30 min, 3 h) is efficiently internalized into CD56-expressing small cell lung cancer (SCLC) cell lines NCI-H526, NCI-H524 and NCI-H69[1].
