The Candidates

INBRX-101 is a recombinant human AAT-Fc fusion protein therapeutic candidate currently being evaluated for the treatment of AATD. Early clinical data has demonstrated a promising pharmacokinetic profile that we believe supports a dosing schedule of every three to four weeks to achieve continuous normal AAT serum concentrations, a significant improvement from patients’ current regimen.

INBRX-109 is a precisely engineered tetravalent sdAb-based therapeutic candidate that agonizes DR5 to induce tumor selective programmed cell death.

INBRX-106 is a hexavalent sdAb-based therapeutic candidate targeting OX40 currently being evaluated in patients with locally advanced or metastatic solid tumors. Signaling through OX40 provides co-stimulation that promotes T-cell expansion, enhanced effector function and memory cell formation, and prevents activation-induced cell death.

INBRX-105 is a tetravalent sdAb-based therapeutic candidate currently being evaluated in patients with programmed death ligand 1 (PD-L1) expressing tumors, including those refractory to, or relapsed from, approved checkpoint inhibitor therapies. INBRX-105 is designed to agonize 4-1BB selectively in the presence of PD-L1.
