Survival data for study mice at 18 days further supports the efficacy synergy of IL12-FHAB co-injected with anti-PD1 by improving the survival rate: (i) for anti-PD1 administration, only one mouse survived out of a total of nine, and (ii) for anti-PD1 + IL12-FHAB administration, seven mice survived out of a total of nine. Additionally, the mice cohorts used in the preclinical efficacy study did not show any weight loss during the study in either the single agent or combination dosing arms.
“We are excited to have demonstrated these important data in an immunologically distinct animal model when IL12-FHAB was dosed in combination with an anti-PD1 antibody,” said John Cini, Ph.D., Sonnet’s Chief Scientific Officer. “Further, this study evaluated the sequence of test article administration, whereby co-injection of IL12-FHAB and anti-PD1 antibody was optimal when compared to administration of either anti-PD1 or IL12-FHAB first. Targeting the tumor by linking IL-12 to an albumin-binding domain extends the cytokine half-life in the body, and we believe that is the key to inducing a successful local immune response in the tumor microenvironment.”
