Immunitas Therapeutics Presents Data for Novel Anti CLEC2D-TLR9 Conjugate Program at the Society for Immunotherapy of Cancer 2023 Annual Meeting

In vitro proof-of-concept for novel myeloid and B cell modulating anti-CLEC2D-TLR9 agonist conjugate program, a compelling immunotherapeutic approach to induce T and NK cell recruitment in tumors with otherwise low immunological activity

WALTHAM, Mass., Oct. 31, 2023 /PRNewswire/ -- Immunitas Therapeutics ("Immunitas"), a clinical stage precision immunotherapy company committed to discovering and developing novel, differentiated therapeutics for patients with cancer, today announced it will present the first proof-of-concept data on its second program, a myeloid and B cell modulating anti CLEC2D-Toll-like receptor 9 (TLR9) agonist conjugate, at the Society for Immunotherapy of Cancer's 38th Annual Meeting (SITC 2023), held November 1-5.

Presentation Details for SITC 2023
Title: Anti CLEC2D-TLR9 agonist conjugate binds to and internalizes CLEC2D on myeloid cells, plasmacytoid DCs and B cells leading to robust TLR pathway activation and inflammatory cytokine production
Abstract Number: 1131
Date/Time: Friday, November 3, 2023, 9:00am – 7:00pm PDT

About CLEC2D
CLEC2D is a protein broadly expressed on a subset of immune cells which, upon internalization, acts as a vehicle to deliver histone/CpG complexes to endosomal toll-like receptor 9 (TLR9), stimulating an inflammatory response. Harnessing this biology offers a compelling immunotherapy approach that stimulates inflammatory responses that may improve recruitment of functional T and NK cells in tumors with otherwise poor T cell infiltration. Building on biology supporting its lead investigational candidate, IMT-009, Immunitas is developing a novel anti CLEC2D-TLR9 agonist immune stimulating antibody complex (ISAC) comprising a fully human anti-CLEC2D antibody conjugated to aCpG oligonucleotide. This molecule is capable of triggering TLR9 pathway activation in myeloid cells, B cells, and plasmacytoid dendritic cells enabling induction of sustained T cell immunity.
