Tarlatamab
Based on 4 publication(s) in Google Scholar
Tarlatamab (AMG-757) is a bispecific T-cell engager (BiTE) antibody targeting delta-like ligand 3 (DLL3). DLL3 is a target that is selectively expressed in small-cell lung cancer (SCLC) tumors, but with minimal normal tissue expression. Tarlatamab has the KDs of 0.64 nM and 0.50 nM for human and nonhuman primate (NHP) DLL3, respectively. Tarlatamab has the KDs of 14.9 nM and 12 nM for human and NHP CD3, respectively. Tarlatamab is a first-in-class HLE BiTE immuno-oncology therapy targeting DLL3 and has the potential for SCLC research.

体外実験
Tarlatamab (AMG-757; 0-10 nM; 48 hours) has potent, specific cytotoxic activity against DLL3-expressing SCLC cell lines in vitro[1].
Tarlatamab (0-10 nM; 4-72 h) increased granzyme B levels and cytotoxicity over time, with maximal signal observed at 48 hours. Markers of T-cell activation or inflammation, CD69, CD71, PD-1, and PD-L1 (37-39) were upregulated[1].

Cell Line:SCLC cell lines (DMS 79, NCI-H2171, NCI-H889, SHP-77, NCI-H211,COR-L279)
-
Concentration:0-10 nM
-
Incubation Time:48 hours
-
Result:AMG 757 effectively engaged human T cells to kill SCLC cell lines, including those with very low DLL3 expression levels.
体内実験
Tarlatamab (IP; 12 μg/kg; single dose) has a mean half-life of 234 hours (9.8 days), a mean clearance of 0.487 mL/hour/kg and a steady-state volume of distribution of 146 mL/kg in nonhuman primates (NHPs)[1].

Animal Model:Female NOD.Cg-PrkdcscidIl2rgtm1Sug/JicTac (NOG) mice with patient-derived SCLC tumor fragments (LXFS 1129 and LXFS 538)[1]
-
Dosage:3 mg/kg
-
Administration:IP; once weekly for 3 weeks
-
Result:Led to 83% tumor regression and an overall significant reduction in tumor volume compared with that in mice which received a control HLE BiTE molecule in the LXFS 1129 model.
Induced 98% tumor regression in the LXFS 538 model.

RNA extraction experimental
By lysing cells, releasing RNA, and removing impurities such as proteins and DNA, high-purity RNA products are finally obtained. The commonly used traditional method is the guanidine isothiocyanate/phenol/chloroform method (Trizol), which is suitable for a variety of animal materials including animal tissues, microorganisms, cultured cells, etc., and most plant materials.
