Title:
1438 IKS03, a Novel CD19-Targeted Antibody Drug Conjugate, Induces Target Dependent In Vivo Cell Killing of B-Cell Lymphoma Xenografts By DNA Crosslinking
Excerpt:In vivo efficacy was evaluated in CD19-expressing preclinical human xenograft models representing different subtypes of B-NHL. IKS03 was highly active against Farage and OCI-LY10 DLBCL xenografts as well as Granta-519 MCL xenografts in SCID mice with durable tumor regressions observed following treatment with a single dose of 0.1 to 0.3 mg/kg.

Title:
IKS03, a Next Generation CD19-Targeted Antibody Drug Conjugate, Shows Potent Activity in Preclinical Models of Aggressive B-Cell Lymphomas
Excerpt:In vivo efficacy was evaluated in CD19-expressing preclinical human xenograft models representing different subtypes of B-NHL….In vivo efficacy was evaluated in CD19-expressing preclinical human xenograft models representing different subtypes of B-NHL. Granta-519 cells contain the CCND1 t(11;14) translocation often present in mantle cell lymphoma (MCL). IKS03 was highly active against Granta-519 xenografts in SCID mice with complete tumor regressions observed with a single dose of 0.1 mg/kg. Efficacy was further evaluated in CD19-positive, low passage DLBCL patient-derived xenograft (PDX) models of known genomic profiles. IKS03 was highly active yielding complete tumor regressions...
