Summary

Recent reports have identified a specific oncogenic mutation L265P of the MYD88 gene in approximately 30% of the patients with the activated B-cell (ABC) type of Diffuse Large B Cell Lymphoma (DLBCL). MYD88 is an initial adapter linker protein in the signaling pathway of the Toll Like Receptors (TLRs), including the endosomal TLRs 7, 8, and 9, for which the ligands are nucleic acids. IMO-8400 is an oligonucleotide specifically designed to inhibit ligand activation of TLRs 7,8, and 9. Recent studies indicate that in the presence of L265P mutation ligand activation of those TLRs results in markedly increased signaling with subsequent increased cell activation, cell survival, and cell proliferation. The scientific rationale for assessing the use of IMO-8400 to treat patients with DLBCL and the L265P mutation is based on laboratory observations that IMO-8400 inhibits ligand-based activation of cells with the mutation and decreases the survival and proliferation of the cell populations responsible for the propagation of the disease.

Detailed description

Eligible subjects will be enrolled and assigned to one of five dose cohorts. Treatment will be administered by subcutaneous injection until progression or intolerable toxicity.
