eFFECTOR is a clinical stage biopharmaceutical company focused on pioneering the development of a new class of oncology drugs referred to as selective translation regulator inhibitors (STRIs). eFFECTOR’s STRI product candidates target the eIF4F complex and its activating kinase, mitogen-activated protein kinase 1/2 (MNK 1/2). The eIF4F complex is a central node where two of the most frequently mutated signaling pathways in cancer, the PI3K-AKT and RAS-MEK pathways, converge to activate the translation of select messenger RNA into proteins that are frequent culprits in key disease driving processes. Each of eFFECTOR’s product candidates is designed to act on a single protein that drives the expression of multiple functionally related proteins, including oncoproteins and immunosuppressive proteins in T cells, that together control tumor growth, survival and immune evasion. eFFECTOR’s lead product candidate, tomivosertib, is a MNK 1/2 inhibitor. KICKSTART, a randomized, double-blind, placebo controlled Phase 2b trial of tomivorsertib in NSCLC in combination with pembrolizumab is currently open for enrollment. Zotatifin, eFFECTOR’s inhibitor of eIF4A, is currently in the dose-escalation portion of a Phase 1/2 trial, with Phase 2a expansion cohorts expected to initiate in the second half of 2021. eFFECTOR has a global collaboration with Pfizer to develop inhibitors of a third target, eIF4E. eFFECTOR plans to evaluate zotatifin as a potential host-directed anti-viral therapy in patients with mild to moderate COVID in collaboration with University of California, San Francisco, under a $5 million grant sponsored by the Defense Advanced Research Projects Agency.
